## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a Utility patent application based on a previously filed U.S. Provisional Patent Application U.S. Ser. No. 62/206,560 filed on Aug. 18, 2015, the benefit of the filing date of which is hereby claimed under 35 U.S.C. §119(e) and which is further incorporated by reference in its entirety.


TECHNICAL FIELD
The present invention relates generally to vehicle monitoring, and more particularly, but not exclusively, to diagnosing issues identified by monitoring vehicle activity using a plurality of sensors.
BACKGROUND
Currently, multiple systems exist that directly monitor diagnostic information for vehicle through one or more diagnostic ports that may use one or more diagnostic reporting protocols, such as, On Board Diagnostic-II (OBD2). This information, while available, may be limited in that the diagnostics ports only provide data from sensors that are mounted in the vehicle, and may not provide accelerometer information real-time, at sufficiently high reporting rates, nor do vehicles currently have real-time accelerometers at the steering wheel. Further, studies have also shown that as vehicles age or if there are mechanical issues with alignment, wheel balancing, engine mounts, tire inflation, vehicle suspension, engine tuning, or the like, the noise and vibrations in the vehicle tend to change and increase. Various vibrations, steering wheel positions, or the like, may generally point to issues with the vehicle that could impact fuel efficiency, comfort, and the safety of the vehicle's occupants. In some cases, it is difficult for sensors currently installed in vehicles to update the standard diagnostic systems (e.g., OBD2 compliant systems) with sufficient vibration/motion related signals to identify unique vibrations and to correlate them with potential issues. Thus, it is with respect to these considerations and others that the present invention has been made.

Connected Bluetooth Low Energy Vehicle Activity Monitor Description
One embodiment of the Connected Bluetooth Low Energy Vehicle Activity Monitor may be found in FIG. 1. In this embodiment, the automotive activity monitor platform leverages a plurality of sensors (3) coupled with a Bluetooth Low Energy (BTLE) radio System in Package or SiP (1) to monitor the status and activity of a vehicle without requiring a physical connection to an OBD2 port.
The BTLE SiP (1) may manage a plurality of interface including but not limited to a Button and Input Interface (2), Sensor Circuit (3) containing a plurality of sensors such as a 9-axis accelerometer, ambient noise sensor, and temperature sensor. Furthermore, this system may support a Display (4), and Audio Transducer (5).
The BTLE SiP (1) may receive stable power directly from a replaceable battery, or from a Recharging Circuit (6) that may use as its power source a rechargeable battery. Furthermore, the Recharging Circuit (6) may receive power from one or more external sources such as solar power, 5 v power via the USB port in the vehicle, 12 v power from the vehicle's wiring or a cigarette lighter, or inertial power through energy harvesting.
This Recharging Circuit (6) may also provide the current vehicle battery information to the chip via a Battery Level Detector (8). The BLE SiP (1) may contain an internal or external balun, or may be connected to the Antenna (7) via an external RF matching circuit that matches the digital radio's output to the Antenna (7) thus providing an optimized RF connection.
By mounting the Vehicle Activity Monitor hardware in an ideal location inside the vehicle as shown in FIG. 2 such as directly on the steering wheel (11, 12, 13), or on the steering column (17), the sensor may be used to directly measure the angle of the steering wheel in real-time, as well as vibrations that translate exclusively through the steering column and may be felt by the user under different driving conditions.
Furthermore, as shown in FIG. 2, placement directly on the steering wheel (11, 12, 13, 17) or on the dashboard (14, 16) also offers an ideal location from which to provide a plurality of controls that may be used to access or manage apps that are running on mobile devices today such as mobile phones or tablets.
Unlike the Connected Bluetooth Low Energy Vehicle Activity Monitor, OBD systems must be mounted inside the OBD2 port, which is hidden behind a flap under the dashboard of most vehicles (15). Furthermore, the OBD2 connector may be suspended on wires and thus not provide direct translation of vibrations to the plug-mounted device sensors.
As a result of its convenient mounting locations (11, 13, 14, 16, 17), the Connected Bluetooth Low Energy Vehicle Activity Monitor may support an LED or e-Paper Display, or the like.
In at least one of the various embodiments, Connected Bluetooth Low Energy Vehicle Activity Monitor may be considered to be sensor computers as described below in FIG. 19.
Connected BLE Vehicle Activity Monitor User Interface
One embodiment of the Connected BLE Vehicle Activity Monitor's user interface is shown in FIG. 3. In this embodiment, a Main Button (17b) and LED (18) interface are used to interact with the user. The Main Button (17b) may serve as a trigger to launch one or more features of the associated app on a mobile device (20) via the BLE connection (19). It may also be used to trigger a plurality of 3rd party apps (21) that reside on the mobile device either my sending messages to the cloud, which then trigger and launch the 3rd party app (21), directly via APIs, or through other means based-on the available mobile phone's OS features. Further, in some embodiments, Connected BLE Vehicle Activity Monitors (e.g., sensor computers) may include button 17c, as well as, light ring 17d. In some embodiments, button 17c may be arranged to enable a user to press to provide user input directly on the Connected BLE Vehicle Activity Monitor. Likewise, in some embodiments, light ring 17d may be a LED based ring that may be arranged to provide visual cues to a user.
In another embodiment of the Connected BLE Vehicle Activity Monitor shown in FIG. 4, the Connected BLE Vehicle Activity Monitor may support a rich display (24). In this embodiment, the Connected BLE Vehicle Activity Monitor may also be equipped with a rotating bezel, dial, or detented rotating switch system (23). In some embodiment, there may be an external bezel rings, such as, bezel ring 23b, and an indicator point, such as, indicator point 23c. In this embodiment, the switch may be turned to various positions as indicated by the positional indicator (22) and indicator point 23c. When turned, the bezel (23) may show the logo (24b) for a plurality features or 3rd party apps on the display (24). The system may also transmit information to the app (26) via the BLE link (25) which may then change the selector in the Connected BLE Vehicle Activity Monitor app (26) on the mobile phone to point to a specific app (27).
Because of how BLE devices are handled on the mobile phones today, the apps that are being launched need not be actively running on the mobile device at the time where the button is pressed. Instead, due to the Over the Top (OTT) nature of the Connected BLE Vehicle Activity Monitor app (20, 26), and because of its Bluetooth Low Energy connection.
Data Aggregation
One app that may be launched by the Connected Bluetooth Low Energy Vehicle Activity Monitor is a parking application that resides on the mobile phone. In this manner, as a user approaches the proximity of his or her destination, the user may press the Connected Bluetooth Low Energy Vehicle Activity Monitor's button (17b). The Connected Bluetooth Low Energy Vehicle Activity Monitor may then trigger a command to the phone, which is then interpreted by the Vehicle Activity Monitor App (20, 26)) on the Mobile Phone. In one implementation, the Vehicle Activity Monitor App (20, 26) may then in turn enable the GPS of the Mobile Phone and send the GPS coordinates to a Cloud Server. The Cloud Server may then interpret the GPS coordinates along with the user's profile information, and return the best app for finding parking to the user's Vehicle Activity Monitor App (20, 26). The Vehicle Activity Monitor App (20, 26) may then trigger the proposed parking app (21, 27) or a different app from the available list of apps on the mobile phone.
Thus the Vehicle Activity Monitor App (20, 26)) may trigger a parking app (21, 27), making it active and initiating a parking spot search. The parking app may then in-turn initiate turn-by-turn instructions to lead the user to the parking space without the user having to pull out their phone and physically launch the app.
In one embodiment of the invention, the Connected BLE Vehicle Activity Monitor may use a plurality of color, image, light, and blinking patterns to show the status of the Connected BLE Vehicle Activity Monitor under different operating conditions (28, 29, 30, 31, 32, 33, 34, 35) as shown in FIG. 5. In this embodiment, device states such as CONNECTING (30) may be interpreted as a blinking pattern or open link icon (35). Furthermore, alerts (31) and other notifications may be displayed to the user via changes in the color, icon (35), light, and blinking pattern. These patterns may be assigned to different app or device notifications.
The system may support a plurality of sensors (3), including but not limited to an accelerometer, gyroscope, temperature sensor, an ambient noise sensor, or other environmental sensors such as a particle or gas sensors. These sensors (3) may be connected to a microprocessor (1) that, in-turn may be connected to, or serve as Bluetooth Low Energy radio antenna (7) and therefore may directly feed the app (20,26) with data that can be shared via the cloud with other 3rd party apps or cloud-based services via an in-app API or cloud-based API. Furthermore, the Bluetooth Low Energy radio may use BLE mesh networking and beaconing protocols to broadcast to other devices in the area.
In another embodiment of the system, an LTE-M or other radio may be used to transmit sensor data directly to the cloud, thus enabling data to be interpreted directly by the network computer without the need for a tablet or client computer.
Beaconing, Location, and Parking
While the systems may or may not itself support an onboard GPS, the system may leverage the GPS in the mobile phone or other precise location data to establish the current position of the vehicle. This information may be useful in several applications, including but not limited to parking applications.
In one embodiment, the user may pre-register with a parking authority. As part of the registration, the parking authority may assign a specific user code to the user that may be communicated via the app to the Connected BLE Vehicle Activity Monitor. The Connected BLE Vehicle Activity Monitor may thus be used in conjunction with the mobile phone as a virtual parking meter.
In this embodiment, the Connected BLE Vehicle Activity Monitor may detect if the vehicle has come to a complete stop and that the user has exited the vehicle. In this embodiment, the Connected BLE Vehicle Activity Monitor may always request the current location of the vehicle when the vehicle comes to a complete stop for a period of time that exceeds a threshold, when the driver stops moving the steering wheel, or when the engine gets turned off which it may detect through the change in vibration that occurs when stopping the engine.
Furthermore, this location may be used by the app to register the parking location with a parking authority via the app, and the Connected BLE Vehicle Activity Monitor may switch modes to begin beaconing the current location of the vehicle, together with a secret code representing that the user has a valid parking account and that the vehicle has been registered for parking.
Should the vehicle be parked next to a meter equipped with a Bluetooth Low Energy system, then the parking meter may also confirm that the user is parked in a valid spot, and the parking system may start tallying the time that the vehicle was parked in front of the meter. Furthermore, the system may change the status of the parking meter from a color indicating that there is nobody parked at the meter (e.g. RED) to a color indicating that the vehicle at the meter is parked legally (e.g. GREEN).
Parking enforcement officers may get equipped with an app that also monitors the presence or absence of vehicles equipped with the Connected BLE Vehicle Activity Monitor-based parking system. Thus they may quickly scan for the presence of such vehicles as they drive by, pausing only to ticket vehicles that are not equipped with the system.
External Data Sources
The system may also collect data from external sources via the Vehicle Activity Monitor app (20, 26). Data may include but not be limited to data from other apps, cloud-based services, or third party hardware devices such as OBD2 monitors. Data may include weather, traffic conditions, road conditions, police activity, and other information that may affect the user's commute, or may include detailed vehicle or diagnostic information as may be obtained via 3rd party OBD2 devices.
Data may also be drawn from multiple sources including commercial street map applications, government street/traffic information publicly on the web, or the like, using public or private APIs.
Ultimately, the available data may be used in conjunction with the data created by the Connected BLE Vehicle Activity Monitor to create a picture of the user's specific vehicle environment, vehicular usage model, the condition of the vehicle, in-car schedule, and in-car behavior.
The data may then be used to evaluate and propose behavioral changes that reduce the time spent in the vehicle with the engine running, and thus a reduction in fuel consumption and operating cost.
This predictive modeling may also in turn propose other improvements in daily habits that positively impact the user's commute by anticipating traffic patterns. For example a user may be notified to leave 10 minutes earlier on Mondays due to the increase in traffic that occurs at 9:35 am vs. 9:25 am. This may result in a 10 minute reduction out of an otherwise 40 minute commute (e.g. a 25% saving in commuting time) by bypassing the worst traffic conditions and times.
Other similar models may be derived using a learning engine in the cloud or in the mobile phone app (20, 26). One example of such a flow is shown in FIG. 6 where the User Actions in Vehicle Context are described as a flow diagram. In this example, the user is initially driving (36) and arrives in the proximity of his destination (37). Normally, the user would need to pull out his or her phone at this point in order to trigger a parking app or an equivalent app. When using the Connected BLE Vehicle Activity Monitor, however, the user may simply tap a button thus triggering a sequence of events (38) that ultimately lead to the optimal parking spot being identified. The user may then follow the voice prompts (39) to his or her desired parking place.
As can appreciated by somebody skilled in the art, a similar approach may be used with other apps and software services that can save the user time and money, or make the user more productive while driving without distracting the user from the road ahead.
Connected Bluetooth Low Energy Vehicle Activity Monitor Operation
The Connected Bluetooth Low Energy Vehicle Activity Monitor's (e.g., sensor computer) may be used to manage the user interfaces, send and receive data via the Bluetooth Low Energy wireless link, and manage inter-chip communication. The firmware that controls the circuit, user interfaces, Bluetooth Low Energy wireless link, etc. may also be modular and may include firmware build switches (used by compilers to turn on-and-off firmware modules, features, and function) and thus compile only those sections of firmware that are required to work with the specific device implementation in question.
This Connected Bluetooth Low Energy Vehicle Activity Monitor may therefore be used to drive an audio output such as a Piezo transducer or other speaker through a pulse-width modulated output provided by the Bluetooth Low Energy Radio in the SiP (1) to generate noise whenever a traffic alert or other notification is received. The tone of the alert may vary based-on the type or severity of the notification and thus provide contextual feedback to the user.
The Connected Bluetooth Low Energy Vehicle Activity Monitor's button may be used to trigger multiple actions based-on context. For example, if no alert or notification is present, the button may be used to trigger an action. Alternatively, the button may be used to clear the current notification.
A protocol based on the Connected Device Protocol may be used in order to minimize the amount of Bluetooth communication needed to convey the most valuable information from the Connected Bluetooth Low Energy Vehicle Activity Monitor to the mobile phone.
For example, instead of conveying raw X, Y, and Z acceleration information from the accelerometer via the Bluetooth Low Energy link to the mobile phone, the Connected Bluetooth Low Energy Vehicle Activity Monitor may interpret the information and convert it into valuable metrics such as time spent driving, time spent breaking, time spent accelerating, time spent turning left, time spent turning right, and ride smoothness.
In at least one of the various embodiments, raw data may be sent to a user's mobile phone. In some embodiments, the data may be associated with metadata that may be used to identify the precise context of the captured data. In some embodiments, the metadata may include various contextual information, such as, a plurality of locations, date and time information, steering wheel positions, or the like, that may be related to when the data was captured by the Connected Bluetooth Low Energy Vehicle Activity Monitor.
In at least one of the various embodiments, if the metadata may be captured while the Connected Bluetooth Low Energy Vehicle Activity Monitor (e.g., sensor computer) may be connected with the mobile phone it may be communicated to the mobile phone immediately. Otherwise, in some embodiments, if the metadata may be captured while the Connected Bluetooth Low Energy Vehicle Activity Monitor may be disconnected from the mobile phone, it may be stored in a local memory of the Connected Bluetooth Low Energy Vehicle Activity Monitor. Accordingly, in at least one of the various embodiments, if communication connections are restored, the stored metadata may be provided to another computer, such as, the mobile phone, a network computer, or the like. It is well established that the amplitude of both engine noise and vibration are closely related to the engine RPM as illustrated in FIG. 7 (Engine Noise vs. RPM Example). Furthermore, there is plenty of data that supports that the most economic RPM zone is between idle (usually between 500-800 RPM) and 2500 RPM for most internal combustion engines as shown in FIG. 8 (RPM and Fuel Consumption).
Similarly, there may be a high correlation between the frequency of engine noise and the frequency of vibrations in the vehicle while operating. For example, in some embodiments, the vibration of the vehicle may be correlated to the engine vibrations as shown in FIG. 9.
In this instance, we can see that at 3600 RPM, the engine vibration is approximately 60.1 Hz (43) while the acoustic tone the engine makes is at approximately 59 Hz (44). Thus, by correlating engine noise frequency via the ambient noise sensor (3) and the frequency of the vibration via the accelerometer (3) of the Connected Bluetooth Low Energy Vehicle Activity Monitor of FIG. 1, the firmware can estimate the engine RPM and thus the manner in which the car is being driven.
The Connected Bluetooth Low Energy Vehicle Activity Monitor metrics may be transmitted to and aggregated by the mobile phone app, and may then be related back to CO2 emissions and refined based-on profile information about the vehicle, the driver's behavior, and contextual information provided via cloud-based services and third party data sources such as traffic information, weather information, road conditions, etc.
In one such embodiment, the vehicle's make (e.g. Volkswagen), model (e.g. Jetta), model year (e.g. 2014), fuel type (e.g. Diesel), engine (e.g. 2.0 liter, 4 cylinder TDI) drivetrain (e.g. front wheel drive) may discovered using automated background searches to obtain detailed vehicle information, tire and wheel size information, vehicle history information, fuel consumption statistics from one or more publically available knowledge bases. These statistics may be combined with information about the driver's habits obtained via the accelerometer such as acceleration/deceleration, driving speed at any given time, engine RPM, direction of motion, frequency and speed of directional changes, etc., along with road conditions as measured via the vehicular vibrations while driving to estimate the overall fuel consumption and thus emissions.
These data, once collected, may be uploaded to the cloud to be analyzed or analyzed directly by the mobile phone app. The analysis may provide useful feedback to the user, such as:
a. How much time do I spend in the car with the engine running?
b. How much time do I spend with the engine running where the car is not moving?
c. How long is my typical commute?
d. At which times of the day is the commute the worst?
e. What would be the best time of the day to commute?
This data may be further analyzed, along with traffic data to assess whether there may be timely issues that would affect a user's impending commute. Thus, the mobile phone app may issue alerts or notifications to the user that warn of potential issues that could negatively affect the commute and thus increase the time spent driving.
Connected Device Mesh Networking
As a mobile device may not always be available, and as there are experiences that may benefit from the sharing of information via peer-to-peer intra-vehicular links, a Mesh Networking Protocol has been devised. This protocol maintains the privacy of the user by constantly modifying the vehicle's Bluetooth Low Energy address while simultaneously broadcasting encrypted data to devices in the area that are cloud-connected. Therefore, even if the user is not present, the user may enable his or her mobile device to act as a relay to the cloud, and thus deliver important information to a cloud-based server that may then be used to analyze the data, and inform the vehicle's owner of any anomalies.
Calibrating the Steering Wheel Position
The camera in the mobile phone that is associated with the Connected Bluetooth Low Energy Vehicle Activity Monitor app provides a useful method for calibrating the zero position of the Connected Bluetooth Low Energy Vehicle Activity Monitor (e.g., sensor computer). The method shown in FIG. 10 may be used to calibrate the steering wheel angle.
This basic premise, is that when driving on an even level surface (such as in a parking lot or on a highway) if the vehicle's wheels are well aligned, the steering wheel should remain in a neutral position even if the driver lets go of the wheel. Therefore, if the Connected Bluetooth Low Energy Vehicle Activity Monitor is mounted on the steering wheel (11, 12, 13, 17), then its orientation may be detected and processed using digital image processing techniques.
The user first affixes the Connected Bluetooth Low Energy Vehicle Activity Monitor to the steering wheel of the car and starts driving slowly in a straight line on a level parking lot while removing his or her hands from the wheel.
If the wheels have reached their neutral position, the user stops the car and takes a picture of the front of the car. By using the outline of the dashboard against the contrast of the window, and by using the outlines of the interior features of the car, an artificial horizon may be identified in the image. This horizon may then be used, in conjunction with the position of the steering wheel, to determine the position and angle of the Connected Bluetooth Low Energy Vehicle Activity Monitor. This angle may then be transmitted back to the Connected Bluetooth Low Energy Vehicle Activity Monitor via the Bluetooth Low Energy link, and may be used by the Connected Bluetooth Low Energy Vehicle Activity Monitor as a corrective factor when setting the offset angle of the Connected Bluetooth Low Energy Vehicle Activity Monitor.

FIG. 21 illustrates an overview flowchart of process 2100 for automotive activity monitoring in accordance with at least one of the various embodiments. After a start block, at block 2102, in at least one of the various embodiments, one or one more sensor signal baselines may be established. In at least one of the various embodiments, each vehicle with a sensor computer installed, may be arranged to gather three datasets on day zero; these may be collected during steady state driving at various defined speeds, such as, 25 mph, 45 mph, or 70 mph (or 10 m/s, 20 m/s, or 30 m/s). In some embodiments, this data may serve as operational baselines for a monitored vehicle. After the baselines are collected, data collected from each vehicle trip may be compared to the baseline data.
At block 2104, in at least one of the various embodiments, sensor signals may be monitored. As described above, a sensor computer may include various sensors, such as, accelerometers and/or gyroscopes for detecting one or more signals, such as, vibrations, shock, rotation, tilt, yaw, speed, acceleration, internal sound/noise, external sound/noise, or the like, or combination thereof.

For example, in some embodiments, the system may be configured to collect 10 samples for one or more speeds, such as, 25 mph, 45 mph, 70 mph, and so on. The sampling may occur at an exponentially decaying rate through the length of the trip. For example, in a given trip, data may be collected the first time a car hits a steady state at 25 mph. The next time that speed occurs, data may be collected if more than one minute has elapsed since the first collection or if a recognized event (e.g. road shock) has occurred. The time gap may then be increased geometrically. For example, the time gap may increase from one to two, four, eight etc. If a road shock exceeds a predefined threshold, the timer may be reset.
In at least one of the various embodiments, during a given trip, the first dataset collected may be always be saved. After that, each set collected may be compared to baseline and may be saved only if the difference from baseline exceeds a defined threshold.
