## Background
TECHNICAL FIELD
The present disclosure relates generally to systems and methods for vehicle-to-pedestrian (V2P) communications, and, more particularly, to systems and methods enabling efficient communications between vehicles and pedestrian communication devices, and select activities at the vehicles and pedestrian devices, such as controlling the vehicle or providing vehicle-occupant or pedestrian notifications.
BACKGROUND
This section provides background information related to the present disclosure which is not necessarily prior art.
While vehicles often move near pedestrians, especially in city environments, pedestrians sometimes do not notice vehicles moving nearby. As an example, a pedestrian may not notice that a vehicle is passing quickly on a far side of a truck stopping adjacent the pedestrian, the passing vehicle being blocked substantially from view by the truck.
Vehicle drivers likewise do not see every nearby pedestrian. A driver may not notice, for instance, a pedestrian moving quickly toward the road from behind a visual impediment, such as a wall, building, bus-stop sign, building, or even other pedestrians.
And while autonomous-driving capabilities are developing at a high pace, the vehicles will inevitably, like human drivers, not be able to determine presence or dynamics of every nearby pedestrian.
SUMMARY
Vehicle and pedestrian presence information is very important. Benefits are largely in the area of safety, for vehicle passengers, the pedestrian, and other pedestrians or people nearby, alike. As an example, if a vehicle is driving or being driven relatively fast, on a rural road, main arterial, or other, and the autonomous driving system or driver is not expecting a pedestrian, a notification to the autonomous or human driver that a pedestrian is present is very valuable. Similarly, a pedestrian not expecting a car would benefit from the information that a car is about to pass by.
A path-prediction algorithm, implemented in the vehicle and/or a pedestrian-mobile device, determines when to alert a pedestrian or driver, autonomous or human, about paths potentially crossing or coming near to each other.
In one aspect, the present technology relates to an autonomous-driving vehicle system, for implementation at an autonomous-driving vehicle. The autonomous-driving vehicle system includes a hardware-based processing unit. and a non-transitory computer-readable storage device comprising and input module and an activity module. The input module, when executed by the hardware-based processing unit, obtains input data indicating presence of a pedestrian communication device near the autonomous-driving vehicle. The activity module, when executed by the hardware-based processing unit: (i) determines, based on the input data, in a pedestrian-presence determination, that the pedestrian communication device is or will soon be near the autonomous-driving vehicle, and (ii) determines, based on the pedestrian-presence determination, an autonomous-driving action to be implemented by the autonomous-driving vehicle.

DETAILED DESCRIPTION
As required, detailed embodiments of the present disclosure are disclosed herein. The disclosed embodiments are merely examples that may be embodied in various and alternative forms, and combinations thereof. As used herein, for example, exemplary, and similar terms, refer expansively to embodiments that serve as an illustration, specimen, model or pattern.
In some instances, well-known components, systems, materials or processes have not been described in detail in order to avoid obscuring the present disclosure. Specific structural and functional details disclosed herein are therefore not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present disclosure.
I. Technology Introduction
The present disclosure describes, by various embodiments, vehicle systems configured to detect presence of local pedestrian communication devices, and take one or more responsive actions.
Responsive actions include communicating with the pedestrian mobile devices, for instance, such as to provide messages to the pedestrian devices about vehicle location and trajectory. The messages can be used at the pedestrian devices to provide notifications to the respective device-holding or device-wearing pedestrians, for instance.
Other example responsive vehicle-system actions include affecting vehicle functions, such as changing vehicle light illumination (e.g., flashing high beams), or changing autonomous driving settings in real time (e.g., decelerate, switch lanes, etc.) based on at least a position of the pedestrian communication devices relative to the vehicle or vehicle trajectory.
Vehicle-system actions in some embodiments include communicating notifications to a driver or passenger(s), collectively occupants, of the vehicle based on the pedestrian communication devices sensed.
In various embodiments, aspects of the technology are implemented at the pedestrian devices, and activities include notifying the pedestrian of circumstances involving the vehicle, such as need to stop walking toward the street because the vehicle is moving on an icy road toward the intersection.
Example pedestrian-device activities also include communicating characteristics about the pedestrian to the vehicle(s) for use in vehicle activities. Pedestrian information may include, for instance, information indicating a handicap about the user, such as partial blindness, being in a wheelchair, or a handicap that affects how they walk.
The vehicle can in turn advise the driver or vehicle occupant of the same if relevant, such as if the person is crossing or apparently about to enter the road. In some implementations, the vehicle has autonomous capabilities, and uses the information about the pedestrian in controlling automated-driving features, such as vehicle speed and direction.
Other example implementations of the technology are described below.
While select examples of the present technology describe transportation vehicles or modes of travel, and particularly automobiles, the technology is not limited by the focus. The concepts can be extended to a wide variety of systems and devices, such as other transportation or moving vehicles including aircraft, watercraft, trucks, busses, trolleys, trains, manufacturing equipment (for example, forklift), construction machines, and agricultural machinery, or of warehouse equipment, the like, and other.
While select examples of the present technology describe autonomous vehicles, the technology is not limited to use in autonomous vehicles (fully or partially autonomous), or to times in which an autonomous-capable vehicle is being driven autonomously.
II. Vehicle Systems—FIG. 1
Turning now to the figures and more particularly the first figure, FIG. 1 shows an example host structure or apparatus 10 in the form of a vehicle.
The vehicle 10 includes a hardware-based controller or controller system 20. The hardware-based controller system 20 includes a communication sub-system 30 for communicating with pedestrian communication devices 32 and external networks 40.
By the external networks 40, such as the Internet, a local-area, cellular, or satellite network, vehicle-to-vehicle, pedestrian-to-vehicle, road-side infrastructure networks, the like or other, the vehicle 10 can reach pedestrian communication devices 32 or remote systems 50, such as remote servers.
Example pedestrian communication devices include a user smartphone 321, shown on a first pedestrian 331, a first example user wearable device 322 in the form of smart eye glasses, worn by a second pedestrian 332, and a second example user wearable device 323 in the form of a smart watch also worn by a second pedestrian 332.

Because the example pedestrian communication devices are indicated by reference numeral 32x (321, 322, etc.), pedestrian communication devices are accordingly referred to at times herein generically by the base reference numeral 32.
The vehicle controller system 20, which in contemplated embodiments includes one or more microcontrollers, can communicate with on-board devices (OBDs) via a controller area network (CAN). The CAN message-based protocol is typically designed for multiplex electrical wiring with automobiles, and CAN infrastructure may include a CAN bus. The OBD can also be referred to as vehicle CAN interface (VCI) components or products, and the signals transferred by the CAN may be referred to as CAN signals. Communications between the OBD(s) and the primary controller or microcontroller 20 are in other embodiments executed via similar or other message-based protocol.
The vehicle 10 also has various mounting structures 35. The mounting structures 35 include a central console, a dashboard, and an instrument panel.

Example sensors include a camera 601 positioned in a rear-view mirror of the vehicle 10, a dome or ceiling camera 602 positioned in a header of the vehicle 10, a world-facing camera 603 (facing away from vehicle 10), and a world-facing range sensor 604. Intra-vehicle-focused sensors 601, 602, such as cameras, and microphones, are configured to sense presence of people, activities or people, or other cabin activity or characteristics. The sensors can also be used for authentication purposes, in a registration or re-registration routine. This subset of sensors are described more below.
World-facing sensors 603, 604 sense characteristics about an environment 11 comprising, for instance, billboards, buildings, other vehicles, traffic signs, traffic lights, pedestrians, etc.
In various embodiments, the vehicle 10 is configured to use one or more pedestrian communication devices 32 (for instance, user phone, user wearable, or user plug-in device) effectively as sensors 60 of the vehicle, such as by using information sensed by a pedestrian device 32 and sent to the vehicle 10. The vehicle system can use data from a pedestrian smartphone, for instance, indicating user-physiological data or phone-movement data sensed by a biometric sensor or accelerometer sensor of the phone.
The vehicle 10 also includes cabin output components 70, such as audio speakers 701, and an instruments panel or display 702. The output components may also include a dash or center-stack display screen 703, a rear-view-mirror screen 704 (for displaying imaging from a vehicle aft/backup camera), and any vehicle visual display device 37.

Example structure includes any or all structures like those described in connection with the vehicle computing device 20. A remote device 50 includes, for instance, a processing unit, a storage medium comprising modules, a communication bus, and an input/output communication structure. These features are considered shown for the remote device 50 by FIG. 1 and the cross-reference provided by this paragraph.
While pedestrian communication devices 32 are shown within the vehicle 10 in FIGS. 1 and 2, any of them may be external to the vehicle and in communication with the vehicle.
Example remote systems 50 include a remote server (for example, application server), or a remote data, customer-service, and/or control center.
In a contemplated embodiment, at least one pedestrian communication device 32, such as a smartphone, nearby the vehicle 10 is in indirect communication with the sub-system 30 by way of nearby infrastructure (for instance, beacon, or hotspot), or longer-range communications, such as via a cellular network and the Internet or other communication network 40.

The cabin sensors (601, 602, etc.), of the vehicle sensors 60, may include one or more temperature-sensitive cameras (for instance, visual-light-based (3D, RGB, RGB-D), infra-red or thermographic) or sensors. In various embodiments, cameras are positioned preferably at a high position in the vehicle 10. Example positions include on a rear-view mirror and in a ceiling compartment.
A higher positioning reduces interference from lateral obstacles, such as front-row seat backs blocking second- or third-row passengers, or blocking more of those passengers. A higher positioned camera (light-based (for instance, RGB, RGB-D, 3D, or thermal or infra-red) or other sensor will likely be able to sense temperature of more of each passenger's body—for example, torso, legs, feet.

With location data, the orientation data, and map, navigation, or other database information about the environment that the phone is located in, the user-pedestrian communication device 32 can determine what the device 32 is facing, such as a particular road, building, lake, etc. These features are important to augmented reality applications, for instance, in which the reality captured by a device camera, for example, is augmented with database information (from the device, a vehicle, a remote server or other source) based on the location and orientation of the device.
With the orientation data, the device 32 can also determine how the pedestrian is holding the device, as well as how the user is moving the device, such as to determine gestures or desired device adjustments, such as rotating a view displayed on a device screen.
Other sensors 334 include at least one biometric sensor 328, such as a heart-rate (HR) sensor, a microphone for voice analysis, a salinity sensor, a breath-quality sensors (for instance, breathalyzer), a driver-temperature sensor, an Electrocardiogram (ECG) sensor, Electrodermal Activity (EDA) or Galvanic Skin Response (GSR) sensors, a Blood Volume Pulse (BVP) sensor, an electroencephalogram (EEG) sensor, an Electromyography (EMG), the like, or other sensor(s) for measuring biometric or physiological characteristics of the driver.
The sensor group 360 can include one or more of a wide variety of other sensors 334 for performing the functions described herein, including those which may indicate driver impairment.
Any sensor can include or be in communication with a supporting program, which can be considered illustrated by the sensor icon, or by data structures such as one of the applications 302N. The user-pedestrian communication device 32 can include any available sub-systems for processing input from sensors. Regarding the cameras 328 and microphone 330, for instance, the user-pedestrian communication device 32 can process camera and microphone data to perform functions such as voice or facial recognition, retina scanning technology for identification, voice-to-text processing, the like, or other. Similar relationships, between a sensor and a supporting program, component, or structure can exist regarding any of the sensors or programs described herein, including with respect to other systems, such as the vehicle 10, and other devices, such as other pedestrian communication devices 32.

The modules, sub-modules, and their functions are described more below.
VI. Vehicle Algorithms and Processes—FIG. 5
VI.A. Introduction to the Vehicle Processes
FIG. 5 shows an example algorithm, process, or routine represented schematically by a flow 500, according to embodiments of the present technology. The flow is at times referred to as a process or method herein for simplicity.
Though a single process 500 is shown for simplicity, any of the functions or operations can be performed in one or more processes, routines, or sub-routines of one or more algorithms, by one or more devices or systems.
It should be understood that steps, operations, or functions of the processes are not necessarily presented in any particular order and that performance of some or all the operations in an alternative order is possible and is contemplated. The processes can also be combined or overlap, such as one or more operations of one of the processes being performed in the other process.
The operations have been presented in the demonstrated order for ease of description and illustration. Operations can be added, omitted and/or performed simultaneously without departing from the scope of the appended claims. It should also be understood that the illustrated processes can be ended at any time.
In certain embodiments, some or all operations of the processes and/or substantially equivalent operations are performed by a computer processor, such as the hardware-based processing unit 106 of the vehicle 10 executing computer-executable instructions stored on a non-transitory computer-readable storage device 104 of the vehicle system 20.
VI.B. System Components and Functions
FIG. 5 shows the components of FIG. 4 interacting according to various exemplary algorithms and process flows of the present technology.
Though connections between every sub-module is not shown expressly, sub-modules of the input module interact with each other in various ways to accomplish the functions of the present technology.
As shown in FIGS. 4 and 5, the input module 410 includes the pedestrian-device inputs sub-module 412, the vehicle-inputs sub-module 414, the external-apparatus inputs sub-module 416, and the profiles sub-module 418.
The pedestrian-device inputs sub-module 412, executed by the vehicle processing unit 106, receives data indicating presence of at least one nearby pedestrian communication device 32. The data can be received from the pedestrian communication devices 32, such as from a customized application operating at each pedestrian communication device 32.
This communication exchange can result from the vehicle system 20 regularly sending a signal or communication to be received, and returned, by devices 32 having the application. The pedestrian-device application and the program or application of the vehicle system 20 can then perform a handshake or similar process allowing them to better recognize each other or at least to establish a real-time communication channel.
The data in some embodiments indicates one or more characteristics about each pedestrian communication device 32. Characteristics can include information indicating presence of the pedestrian communication device 32. Other example characteristics including identification information about the pedestrian communication device 32, information about the pedestrian using the pedestrian communication device 32, and dynamics information indicating location, position, impending position, and movement of the pedestrian communication devices 32, for instance.
Regarding presence of the pedestrian communication devices 32, in various embodiments the vehicle system 20 determines that one or more of the pedestrian communication devices 32 is present without assistance of other apparatus, such as roadside infrastructure, or cellular or other communication networks. In other embodiments, the vehicle 10 uses such assistance.
The vehicle 10 is configured in various embodiments to receive communications directly from pedestrian communication devices 32, thereby indicating at least presence of the pedestrian communication devices 32.
Communications can be transmitted using any suitable protocol, including and not limited to BLUETOOTH®, infrared, infrared data association (IRDA), near field communications (NFC), WI-FI®, the like, improvements thereof, or other. Though usually for vehicle-to-vehicle (V2V) communications, the protocol for subject vehicle-to-pedestrian device (V2P/P2V) communications can utilize Dedicated Short-Range Communications (DSRC).
In various embodiments, the vehicle system 20—the pedestrian-device inputs sub-module 412 or the pedestrian-communications sub-module 422, for instance—determines which pedestrian communication devices 32 are nearby by sending a broadcast, communication, or signal configured to determine if there are any pedestrian devices 32 nearby. The communication or signal is in some cases configured to be responded to only by mobile communication devices having an application configured to process and respond to the communication or signal.
In a contemplated embodiment, at least some information about the pedestrian communication device 32, or the pedestrian 33 using the device 32, is received from a database other than databases of the vehicle 10 and the pedestrian communication device 32.
The information can be received from a remove server 50, for instance. In various implementations, the vehicle system 20 receives information identifying the pedestrian communication device 32 or the pedestrian 33, such as by a unique alpha, numeric, or alpha-numeric code. With the code, the vehicle system 20 can pull or otherwise obtain information about the device or pedestrian, such as information about pedestrian handicaps, from a customized, remote server 50 configured for supporting operations at the vehicle 10 and/or pedestrian communication device 32 according to the present technology.
Communications from and to the pedestrian communication devices 32 can be made via an application at the respective pedestrian communication devices 32 configured for purposes including performing the functions described herein. The communications are also made via an application at the vehicle system 20 configured for performing the functions described herein.
Characteristics about each of the pedestrian communication devices 32 in various embodiments include, and are not limited to, any of:

    
    
        identification information (e.g., device identification code or other identifying information) for the pedestrian communication device 32;
        location or position of the pedestrian communication device 32;
        movement vector indicating direction of movement of the pedestrian communication device 32;
        speed of the pedestrian communication device 32;
        velocity of the pedestrian communication device 32;
        expected further position or location of the pedestrian communication device 32, such as in the expected pedestrian-device location or position that the pedestrian communication device 32 will be at in half a second, or 1 second, etc., as computed at the device 32;
        type of pedestrian communication device 32; and
        weather or other environmental conditions that the pedestrian holding or wearing the device is dealing with, or may have to deal with, such as a snow bank, a puddle, ice, snow, generally, etc.
    
    


In a contemplated embodiment, information indicating presence of one or more pedestrian communication devices 32 is received from an intermediate communication system, such as a server 50, a cellular-network apparatus, or other local communication-network infrastructure.
As an example arrangement, the server 50 includes components to serve needs of at least one of the vehicles 10 and the pedestrian communication devices 32 described herein.
Pedestrian-communication-device location can be provided regularly by the device 32 to the intermediate system, such as to the server 50 every 10 seconds. Vehicle location can be provided in a similar manner from the vehicle 10.
When the server 50 determines that a pedestrian communication device 32 is, based on vehicle and pedestrian device positions, in a predetermined vehicle area, the server 50 can notify either or both of the vehicle 10 and the pedestrian communication device 32 that the other is in its vicinity. In some implementations the server 50 provides location data, advising the vehicle 10 or the pedestrian device 50 of the location of the other.
Characteristics about the pedestrians 33 using the pedestrian communication devices 32, in various embodiments, include any of a wide variety of types of information, any of which can be pedestrian-profile information. Example characteristics, represented in communications transmitted, include information indicating:

    
    
        a handicap, such as being partially or fully blind, in a wheel chair, on crutches, unable to walk fast, unable to walk at a normal pace, etc.;
        age, such as whether the pedestrian is a child or elderly; and
        drowsiness, or alert level;
        whether they are using their device 32—e.g., texting, emailing, watching a video, on a phone call, etc.
        movements of a pedestrian, such as data indicating that they are standing up, walking, etc.; and
        preferences of the pedestrian, such as types of communications or notifications they prefer, such as text, screen alerts, audible alerts, haptic alerts, high beam light conformation from approaching vehicles in the dark, etc.
    
    


Information, such as pedestrian handicap, age, etc. may be determined in any suitable manner, such as by user input, user profile, physiological sensors, pedestrian-device app output, etc.
Data sent to the vehicle 10 from the pedestrian communication device 32 is in various embodiments generated at, received by, or otherwise obtained by the pedestrian communication device 32.
Pedestrian-device data can be obtained from pedestrian-device sensors, for instance. In a contemplated embodiment, the pedestrian-device data includes information input by the pedestrian, such as physiological information, such as information indicating that the pedestrian's foot or leg hurts or that they for are having trouble walking or moving at a normal rate. Such information may be determined in any suitable manner, such as by user input, user profile, physiological sensors, or a sensor measuring a pedestrian walking gate and comparing it to a baseline.
The vehicle-inputs sub-module 414, when executed by the hardware based processing unit, generates, receives, or otherwise obtains information indicating characteristics about the vehicle 10 or vehicle environment, for processing at the activity module 420.
Characteristics about the vehicle 10 in various embodiments include, and are not limited to, any of:

    
    
        information from vehicle sensors 60, such as any sensor data used in effecting autonomous driving;
        location or position of the vehicle 10;
        movement vector indicating direction of movement of the vehicle 10;
        speed of the vehicle 10;
        velocity of the vehicle 10;
        expected future position or location of the vehicle 10, such as the location or position that the vehicle 10 will have in half a second, one second, etc., as computed at the vehicle 10; and
        weather conditions, whether sensed at the vehicle 10, such as icy road, slick road, potholes, fog or other limited vision status (driver or vehicle vision), or vision-affecting condition, etc.
    
    


Characteristics related to the vehicle 10 can also relate to a driver or passenger (collectively, occupants) of the vehicle 10. These personnel-related characteristics, in various embodiments, include and are not limited to:

    
    
        preferences of the vehicle user, such as the type(s) of communications or notifications they prefer, such as text, screen alerts, audible alerts, haptic alerts, etc.;
        a handicap of the user, such as limited sight; and
        age, such as whether the driver is elderly.
    
    


These personnel-related characteristics can also be referred to as vehicle-passenger profile information, vehicle-user profile information, the like, or other.
If a driver has limited sight, for instance, the vehicle system 20 may determine that the driver is less lightly to see the pedestrian 33, and so alert the pedestrian 33 about the vehicle 10 approaching, and possibly about the driver sight disability, and/or alert the driver 20 to ensure they are aware of the presence and location of the pedestrian 33.
The external-apparatus inputs sub-module 416, when executed by the hardware based processing unit, receives data from apparatus or systems external to the vehicle 10, other than the pedestrian communication devices 32. External apparatus can include the remote server 50, roadside infrastructure (communication-capable traffic lights, road-side beacons, etc.), as a few examples.
The external-apparatus inputs sub-module 416 can obtain various types of useful data. The data may include weather or environmental conditions at, adjacent, or near the vehicle 10. The data may be received at the external-apparatus inputs sub-module 416 from a server 50, such as a server providing weather information, a server providing traffic information 50, or the mentioned customized server 50, configured for the purpose of supporting operations of the present technology.
In contemplated embodiments, the information received at the external-apparatus inputs sub-module 416 includes any of the information described above in connection with the pedestrian-device inputs sub-module 412.
The profiles sub-module 418, when executed by the hardware based processing unit, generates or receives profile information about the vehicle 10 or vehicle occupants—driver(s), passenger(s), etc. The profiles sub-module 418 can include any of a wide variety of information, such as default or user-set preferences, user-identifying data, and driver- or passenger-history data, such as past driver or passenger selections and the related circumstance data. Profile data can relate to vehicle 10 users and/or users of the pedestrian communication devices 32.
Example profile data includes information indicating physical characteristics of the user, such as a handicap, such as being partially or fully blind, a drowsiness level, an age or age group (e.g., whether elderly), a weight, a height, heartrate, etc.
Example preferences include types of communications or notifications the corresponding user prefers, such as text, screen alerts, audible alerts, haptic alerts, blinking lights—internal or external vehicle lights, etc.
Input sources to the profiles sub-module 418 include vehicle sensors 60 and local or remote devices 32, 50, via the vehicle communication sub-system 30. Inputs also include a vehicle database, via the database sub-module 414.
The profiles sub-module 418, in various embodiments, stores data received, generated, pre-collected, pre-generated, or otherwise obtained, regarding the driver(s), passenger(s), or pedestrians. The data can be stored in corresponding profiles—e.g., driver profile, passenger-1 profile, passenger-2 profile, pedestrian-1 profile, pedestrian-2 profile, etc. The profile can be part of, or accessible by, one or more relevant applications 302.
Regarding the input module 410, generally, any information obtained by the module 410 can be obtained from the data storage device 104. Information generated, received or otherwise obtained at the input module 410 can be stored at the data storage device 104 until needed.
Input-module data is passed on to the activity module 420.
The pedestrian-communications sub-module 422 of the activity module 420, when executed by the hardware based processing unit, determines, based on the data received from the input module 410, communications to send to one or more nearby pedestrian communication devices 32.
In various embodiments, the pedestrian-communications sub-module 422 determines which pedestrian communication devices 32 are nearby based on data from the input module 410, or receives from the input module 410 data already indicating nearby pedestrian communication devices 32. In the latter case, the pedestrian communication devices 32 can be identified by the input module 410 (e.g., by the pedestrian-device inputs sub-module 412), or by another device such as a server 50 determining that the pedestrian communication devices 32 are nearby.
Determining that the pedestrian communication devices 32 are nearby can include, for instance, determining a relative proximity or separation between the vehicle 10 and subject pedestrian communication devices 32 being within a threshold separation or distance.
Or determining that the pedestrian communication devices 32 are nearby can include determining that the pedestrian devices 32 are within a threshold distance of the vehicle 10 or vehicle path, such as within a circular geo-fence, or vehicle-direction defined parabolic or hyperbolic geo-fence, or other shaped fence having a predetermined-size.
The pedestrian-communications sub-module 422 determines, based on input data from the input module, such as regarding any of vehicle position information, pedestrian-device position information, weather or road conditions, etc., a communication to send to one or more of the pedestrian communication devices 32.
The communications to the pedestrian communication device 32 can include any of a wide variety of types of information, instructions, signals, etc. Communications to the pedestrian communication device 32 can include, for instance, a notification configured to cause the device 32 to notify the pedestrian of a present or impending circumstance definitely, likely, or possibly involving the vehicle 10 and the pedestrian communication device 32.
As an example, while the first pedestrian 331 may be preparing to cross an intersection, while a street-side ‘walk’ signal at the corner indicates they can safely walk across, the vehicle pedestrians-communications sub-module 422 may determine based on positions and movements of the vehicle 10 and of the first pedestrian communication device 321, and on an icy road condition, that the vehicle 10 will surely or likely not be able to stop safely before the cross-walk area, and so further determine to send a notification to the first pedestrian communication device 321 for notifying the first pedestrian 331 to not enter the cross walk.
The notification can also include a reason that an action is being taken or recommended—e.g. “APPROACHING VEHICLE UNABLE TO STOP” OR “VEHICLE APPROACHING ON ICE” or “ . . . ON SLICK ROAD SURFACE”). The application of the pedestrian communication device 32, or related profile or preference, is configured or set to, in some implementations providing a notification for user consumption, limit or not include an explanation in order to focus user attention on the notification, such as “DO NOT ENTER CROSSWALK!”
As another example communication, the vehicle communication to the pedestrian communication device 32 can indicate that the vehicle 10 is approaching the pedestrian 33. The communication in some implementations includes related dynamics information, such as the locations of the vehicle 10 and pedestrian device 32, or relative locations, positioning or spacing of the vehicle 10 and pedestrian device 32.
Communications regarding vehicle 10 location, or relative position, spacing, or movement are in some embodiments configured to allow the pedestrian communication device 32 to use data in the communication to show the position, spacing, etc. on a map at a display of the pedestrian communication device 32. Such communications can be sent directly to detected devices, and in some cases is broadcast for any pedestrian device to receive, directly or indirectly via local infrastructure, other mobile devices, or other vehicles, for instance.
In some implementations, some of the communications are provided by the vehicle 10 to the pedestrian communication device 32 to advise the pedestrian communication device 32, and not necessarily to notify the pedestrian 33, of present circumstances. The communication can advise of the dynamics information, such as the location or relative location of the vehicle 10 and/or pedestrian-vehicle separation distance, for instance, and not lead to the pedestrian communication device 32 notifying the pedestrian 33. The dynamics information may not indicate an impending emergency situation that the pedestrian 33 should be notified of, for example.
The vehicle-communications sub-module 424, determines, based on input from the input module 410, any communications to be communicated to an occupant of the vehicle 10. In the event of a driver-driven vehicle 10, the communication can advise the driver of the presence, location, and movement of one or more nearby pedestrian communication devices 32, and thereby of the one or more nearby pedestrians 33 using the devices 32.
Relative position and movement is in some embodiments shown on a map at the vehicle 10, for instance, at the visual display 37.
Notification to the driver of the vehicle 10 can include an alert advising expressly that the driver should alter driving, such as by slowing, accelerating, and/or turning the vehicle 10, based on input data from the input module 420. The alert, as with all communications described herein, can be made by way of any one or more communication types or modes, such as by text, tone, audible words, haptic output, lights or icons, the like, or other.
In a contemplated embodiment in which the vehicle has fully or partially autonomous driving features, the vehicle 10 may determine to takeover some or all control, from manual control, to avoid an incident involving the pedestrian 33. The takeover can be effected with communication to the driver via the vehicle-communication sub-module 424. The vehicle maneuver can be arranged via the vehicle-controls sub-module 426, described more below.
As another example vehicle communication, the vehicle-communication sub-module 424 in some embodiments provides a communication to passengers, of a vehicle being driven autonomously, advising that the vehicle is making or about to make a new maneuver, and perhaps an explanation therefor—e.g., because of a nearby pedestrian 33 and a slick road condition. Again, relative position and movement is in some embodiments shown on a map at the vehicle 10, for instance, at the visual display 37.
The vehicle-controls sub-module 426, executed by the processing unit 106, determines one or more automated vehicle maneuvers to take based on input data from the inputs module 410.
Continuing with prior examples, the vehicle sub-module 426 may determine, considering, for instance, vehicle dynamics (location, velocity, etc.), pedestrian-device dynamics, and road conditions, such as a snowy or otherwise slick road, that earlier or harsher (than previously planned) braking is necessary in order to ensure or better ensure that the vehicle 10 will not come near a pedestrian 33.
In various embodiments, planned vehicle and/or pedestrian(s) paths could be enhanced using vehicle and pedestrian presence information. In any embodiment, navigation information may be incorporated, such as in evaluating or planning a path based on vehicle and pedestrian(s) presence and location information. Relevant information in some embodiments includes past dynamic path for the vehicle or pedestrian(s). As an example, if the vehicle is being driven or autonomous driving toward a user home, and is about to turn left, and a pedestrian is shortly ahead on the left, the driver (human or autonomous) and/or the pedestrian would be notified. A pedestrian on the right of the vehicle need not to be notified, and the vehicle may not advise the driver of the pedestrian on the right because the risk of problem is very low. These aspects can be implemented accordingly via pedestrian mobile devices, such as via a standard or walking-mode of a navigation system they are using, whether the pedestrian walking, has been standing without moving for some time, etc.
The external-communications sub-module 428, when executed by the processing unit 106, provides communications to destination systems or apparatus external to the vehicle 10, other than the pedestrian devices 32 as the destinations. The other systems may include, for instance, roadside infrastructure, such as a smart-traffic light, roadside beacon, or remote server 50. A communication to a traffic light may instruct the light to change a pedestrian signal to “DON'T WALK”, or keep it at “DON'T WALK” based on vehicle dynamics, pedestrian device dynamics, and road conditions.
Communications to external systems can also indicate anything about present conditions, such as vehicle dynamics and identity, dynamics and identity of nearby pedestrian communication devices 32, decisions made by the vehicle system 20, accordingly, and supporting reasons for the decisions.
In various embodiments, decisions are made together about vehicle and pedestrian path based on their presences and any other relevant information, such as other nearby pedestrians, traffic, obstacles for the vehicle or passengers, etc. The decisions can be made by one or both of the vehicle system and the pedestrian mobile device. In some embodiments, the vehicle and/or pedestrian device includes a negotiation sub-module. The negation sub-module can include or be a part of any of the sub-modules of the activity module 420, and is considered illustrated generally by the activity module in FIG. 4. The negotiation can be part of the vehicle-controls sub-module 426 and the pedestrian-communications sub-module 422, for instance—determining vehicle dynamics via the first 426, and how to instruct or agree with the pedestrian or pedestrian mobile device vis the latter 422. The operations can also include interaction between or more vehicle sub-modules, such as the vehicle-controls sub-module 426 communication and negotiating with an analogous, or algorithmic counterpart, pedestrian-controls sub-module of the pedestrian mobile device.
on top of the notification module. The negotiation sub-module in various embodiments includes one or more algorithms configured to make decisions about vehicle and/or pedestrian path. The vehicle and pedestrian device systems communicate with each other in real time to determine a best routing or movement for the vehicle and/or pedestrian under the circumstances. The interaction can be analogous to human-to-human, you-first or me-first scenario, wherein people agree mutually on dynamics of them by a spoken or unspoken negotiation. As an example implementation, rather than simply notifying or warning a pedestrian via the pedestrian device of an upcoming vehicle, the vehicle could send consecutive messages that it has detected the pedestrian and is therefore planning to change lanes, thereby advising the pedestrian that they need not, for instance, back up or change their course. Or in the same case, if a pedestrian profile in the pedestrian mobile device indicates that the pedestrian moves very slowly, such as due to age or handicap, the pedestrian device may reply with a message, before the vehicle changes lane, advising the vehicle that it need not change lane because there is not a risk of interaction—i.e., the vehicle will be long past by the time the pedestrian reaches the curb.
Systems-update sub-module 429 initiates update of the vehicle data storage unit 104. Update information can indicate, for instance, a user-profile preference update determined by the systems-update sub-module 429 or another module or sub-module based on user feedback, input or activity.
If in response to the vehicle 10 notifying the vehicle driver by two modes, haptic and audio, for instance, the driver may respond to the vehicle 10 indicating that audio alone is preferred, or that haptic is not preferred. The update, if permissible—the user cannot change a preference so that no alert is provided in emergency situations, for instance—is made in the appropriate storage 104 location, such as in an appropriate user profile.
In contemplated embodiments, some of the output of the activity module 420 is provided to the input module 410, for use in processing at input module 410. This feedback is indicated schematically by arrow 411.
Output of the activity module 420 is in various embodiments provided to sub-modules of the output module 430.
The sub-modules of the output module 430 format, convert, or otherwise process output of the activity module 420 as may be needed prior to delivering output or initiating an actuation, communication, or other action.
As shown, example system output components include vehicle speakers, screens, or other vehicle outputs 70.
Example system output components can also include vehicle occupant communication devices 32, such as smartphones, wearables, and headphones.
Example system output components can also include remote systems 50 such as remote servers and driver computer systems—for instance, home computer. The output can be received and processed at these systems, such as to update a driver profile with a determined preference, activity taken regarding the driver, the like, or other.
The occupant-notification sub-module 432 initiates provision of communications to the driver and/or passengers of the vehicle 10, as determined by the activity module 420, such as by the vehicle-communications sub-module 424 of the activity module 420.
The communications are provided via any output communication device of the vehicle output devices 70.
The pedestrian-communications sub-module 432 initiates provision of communications to pedestrian communication devices 32, whether for delivery to the corresponding pedestrian(s), as determined by the activity module 420, such as by the pedestrian-communications sub-module 422 of the activity module 420. The communications are delivered from the vehicle 10 by any vehicle communication device 30 and any suitable communication protocol—BLUETOOTH, DSRC, etc.
The vehicle control output sub-module 434 initiates vehicle functions. Example vehicle functions include and are limited to fully or partially autonomous driving functions, based on output from at least the vehicle-controls sub-module 426 of the activity module 420. Vehicle functions in various embodiments include maneuvers required to avoid or limit risk of coming near a nearby pedestrian 33, or blinking of high-beam lamps, as a few more examples.
In various embodiments, information obtained from the pedestrian mobile device is used in a vehicle navigation system, whether the use relates to the pedestrian. The information can be output by vehicle control output sub-module 434, for instance, and/or the vehicle-controls sub-module 426, as examples. The information can be used to enhance, or supplement, a machine-vision sub-system of the vehicle, for instance. As pedestrian-safety example, if an obscured pedestrian (not visible to the vehicle or driver) is detected by wireless communication with the pedestrian's mobile device, information from the pedestrian device or indicating pedestrian-device presence can be added as an input for processing at the vehicle navigation system, whether as if from the machine-vision sub-system. Similarly, if a vision-based vehicle sub-system is “unsure” of the presence of a pedestrian—has determined that there may be a pedestrian nearby, but not with high likelihood or heavily-corroborating sensor data, information from or about the pedestrian device can be used to corroborate whether the pedestrian is presence, where they are located, how they are moving or planning to move, etc.
The external-communications sub-module 436 initiates, based on output of the activity module 420—from at least the external-communications sub-module 428—sending of communications to devices, systems, or apparatus external to the vehicle 10 other than the pedestrian communication devices 32. The communications are delivered from the vehicle 10 by any vehicle communication device 30 and any suitable communication protocol—WI-FI, BLUETOOTH, cellular, satellite, etc.
In various embodiments, the external-communications sub-module 436 determines communications to provide to systems external to the vehicle 10, such as to other vehicles, a user computer, and a customer service center such as the OnStar® center, which can be configured to in turn take any of a variety of actions, such as notify vehicle occupants, users, or owners, vehicle fleet managers, the like, or other.
The output module 430 can also include a sub-module, which can be any of the output sub-modules shown, or another, configured to update the vehicle storage device 104 with data indicative of determinations or output of the output module 430, or to update vehicle user profiles or ancillary data 112. Output of the output module 430 can also be provided to the input module 410 and used in input module 410 processing described herein. The feedback referenced above in this paragraph is indicated schematically by arrow 431.
The process 500 can end or any one or more operations of the process can be performed again.

Vehicle-to-pedestrian (V2P) in various embodiments include features for interacting with pedestrians 33, their devices 32, and vehicle occupants 10, and/or the vehicle 32, in relatively higher-risk situations. One aim of V2P system and methods is to alert a pedestrian 33 of a vehicle 10 that might harm them, and to alert the vehicle 10 of presence the pedestrian 33. The notice to the pedestrian device 32 can indicate certain conditions, such as vehicle dynamics, that put the pedestrian in danger under the circumstances. Particularly vulnerable pedestrians or situations include, for example:

    
    
        A child on a scooter or running;
        a blind person;
        a vehicle approaching from behind a curve or behind another vehicle;

Vehicle-to-pedestrian (V2P) in various embodiments include features for interacting with pedestrians 33, their devices 32, and vehicle occupants 10, and/or the vehicle 32, in relatively lighter-risk situations. As provided, aims of V2P system and methods include alerting a pedestrian 33 of a vehicle 10 that might harm them, and to alert the vehicle 10 of presence the pedestrian 33.

    
    
        The main aim of the V2P system and methods is to maintain a bi directional communication between the pedestrian and the vehicle systems. For example:
        The vehicle alerts the pedestrian in order to avoid a hazard—flood, splash of water on road, etc.
        Bus/taxi notification to pedestrians waiting for services, such as:
        
            An elderly person who might not be attentive, and included in his profile they prefer to take bus line 27. When line 27 approaches his station, a notification is sent to his pedestrian communication device 32.
            For gaming—a pedestrian might get an additional score in a computer game when his behavior in or near roads is cautious or when the pedestrian performed a pre-communicated mission in the game, such as performing a task to confirm, via their pedestrian communication device 32, that the pedestrian recognizes a particular vehicle on the road, such as by directing a device 32 camera to the vehicle or inputting information about the vehicle 10.
