## Background
RELATED APPLICATIONS
This application is a continuation-in-part of U.S. patent application Ser. No. 12/536,205 entitled “Mobile Communication Device Linked to In-Vehicle System” filed on Aug. 5, 2009, the content of which is incorporated by reference herein in its entirety.


BACKGROUND
1. Field of the Invention
The present teachings relate to methods, in-vehicle systems, and mobile communication devices in which an in-vehicle system receives information from and sends information to a mobile communication device linked to the in-vehicle system via a short-range communication connection.
2. Discussion of the Related Art
Currently, for hands-free communication within an automobile, a handheld wireless mobile phone in a passenger compartment of an automobile may wirelessly link to an in-vehicle system. Typically, the mobile phone and the in-vehicle system connect to one another using a short-range wireless communication technology, such as Bluetooth® (Bluetooth is a registered trademark of Bluetooth Sig, Inc., a Delaware corporation, with an office in Bellevue, Wash.). Generally, the in-vehicle system is limited to providing only basic phone operations to the wirelessly linked mobile phone, such as phone calls, address book searching, and basic text messaging features.
Today, a user's mobile phone is his/her communication center. For example, a user may use a mobile phone for online banking, phone calls, text messaging, viewing and sending e-mails, instant messaging, Internet searching, as well as other uses. However, existing in-vehicle systems are unable to easily access a mobile phone to communicate messages to a user, such as a driver. One possible solution to this problem is to install a phone module in the automobile and have the in-vehicle system use the phone module to communicate with a user's mobile phone via a standard phone call. However, such a solution may be more expensive and may have future compatibility issues if large changes are made to cellular communication infrastructure.
SUMMARY
This Summary is provided to introduce a selection of concepts in a simplified form that is further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.
An in-vehicle system may detect an occurrence of a triggering event. A triggering event can be a single event, a plurality of events or a plurality of events that occur in a particular order. Examples of triggering events may include: vehicle ignition switch on; vehicle ignition switch off; vehicle located at a particular type of location, opening or closing a door, inserting or removing a key from the ignition, as well as other events. In addition, other example events can include any number of events in combination or in a particular order. Upon detection of a triggering event, the in-vehicle system may communicate with a wireless mobile communication device via a short-range communication link. As an example, when a vehicle ignition switch off triggering event is detected, the in-vehicle system may send information to the wireless mobile communication device, where the information may be stored.
A user may modify at least some of the information stored on the wireless mobile communication device when the user is away from the vehicle. Upon returning to the vehicle, the in-vehicle system may detect a vehicle ignition switch on triggering event. The in-vehicle system may notify the wireless mobile communication device of the detected triggering event, which may cause the wireless mobile communication device to send the stored information to the in-vehicle system via a short-range communication connection.
Some embodiments of the wireless mobile communication device may forward at least some information received from the in-vehicle system to a remote processing device for further processing. Some embodiments of the wireless mobile communication device may also include an application that may be downloaded and installed to a wireless mobile communication device. When executed by the wireless mobile communication device, the application may send information stored on the wireless mobile communication device to an in-vehicle system and/or may receive information from the in-vehicle system for storage on the wireless mobile communication device via a short-range communication link.
In one embodiment, destination information is shared between the in-vehicle system and the wireless mobile communication device. The in-vehicle system detects an occurrence of a trigger event (e.g., vehicle ignition shut off) while the in-vehicle system is providing navigation guidance to a desired destination. Responsive to detecting the occurrence of the trigger event, the in-vehicle system determines whether to send the destination data to a mobile communication device. Responsive to determining not to send the destination information to the mobile communication device, the in-vehicle system performs a background information transfer from the in-vehicle system to the mobile communication device. Responsive to determining to send the destination data to the mobile communication device, the in-vehicle system performs an information transfer of the destination data to the mobile communication device.
The mobile communication device receives the destination data corresponding to the desired destination. The mobile communication device displays a prompt requesting a user to select whether or not to continue to the desired destination and receives a response to the prompt from the user. Responsive to the user indicating that the user does not want to continue to the desired destination, the mobile communication device stores the destination data. Responsive to the user indicating that the user wants to continue to the desired destination, the mobile communication device provides navigation instructions to the desired destination using the destination data.

DETAILED DESCRIPTION
Overview
An in-vehicle system, within a vehicle, may detect an occurrence of a triggering event. A triggering event can be a single event, a plurality of events or a plurality of events that occur in a particular order. Examples of triggering events may include: vehicle ignition switch on; vehicle ignition switch off; vehicle located at a particular type of location, opening or closing a door, inserting or removing a key from the ignition, as well as other single events, or other events in combination or in a particular order. In some embodiments, the in-vehicle system may include a navigation unit and the triggering event may include: (a) detecting the vehicle being located at a particular type of location such as, for example, a point of interest, including a fueling station, a restaurant, a movie theater, or other type of location; (b) detecting the vehicle being located at a fueling station and a refueling door of the vehicle being sensed to be in an open position; and (c) detecting the vehicle being located near a restaurant, to which the navigation unit provided guidance for the vehicle to reach; as well as other triggering events.
Upon detecting the occurrence of a triggering event, the in-vehicle system may determine whether a connection exists between the in-vehicle system and a wireless mobile communication device such as, for example, a mobile phone or other communication device. If the connection exists, the in-vehicle system may send information to the wireless mobile communication device. The in-vehicle system and the wireless mobile communication device may communicate with each other using short-range communication technology such as, a wireless short-range communication technology, for example, Bluetooth® or other short-range communication technology, for example, Universal Serial Bus (USB). The wireless mobile communication device may receive the information and present the information on a display of the wireless mobile communication device.
In some embodiments, the information sent to the wireless mobile communication device may be in the form of a prompt to provide information to the user of the wireless communication device. In some embodiments, the prompt may be presented in a pop-up style window on the display. In other embodiments, the prompt may also request information from a user of the wireless mobile communication device. A user may provide the requested information via the wireless mobile communication device, which may then send the requested information to the in-vehicle system using the short-range communication technology.
In some embodiments, regardless of whether an in-vehicle system does or does not include a navigation system, the in-vehicle system may detect an occurrence of a triggering event and may perform an action involving one or more short-range communications with a wireless mobile communication device.
For example, the in-vehicle system may detect an occurrence of a first type of triggering event and, as a result, may send a prompt to the wireless mobile communication device via a short-range communication connection. The wireless mobile communication device may display the prompt requesting information and a user may provide the requested information via the wireless mobile communication device. The wireless mobile communication device may then send the requested information to the in-vehicle system.
When the in-vehicle system detects an occurrence of a second type of triggering event, the in-vehicle system may send, via the short-range communication connection, second information to the wireless mobile communication device, which may then receive and store the second information and/or may send the second information to a remote processor, such as, for example, a server. In some embodiments, the second type of triggering event may include turning a vehicle ignition switch off, or other triggering event, and the second information may include vehicle status information, or other information.
When the in-vehicle system detects an occurrence of a third type of triggering event, the in-vehicle system may send to the wireless mobile communication device, via the short-range communication connection, an indication of the occurrence of the third type of triggering event. In response to receiving the indication, the wireless mobile communication device may send stored second information to the in-vehicle system via the short-range communication connection. In some embodiments, the third type of triggering event may include turning a vehicle ignition switch on, or other triggering event.
Examples of how embodiments may be used may include, but not be limited to: (a) detecting a vehicle being located at a fueling station, detecting an existing connection between an in-vehicle system and a wireless mobile communication device, sending a prompt to the wireless mobile communication device requesting information regarding a price of fuel per unit and a number of units purchased, and receiving a response, from the wireless mobile communication device, including the requested information from the user; (b) detecting the vehicle being located near a restaurant, to which the in-vehicle system provided the vehicle with navigation guidance, detecting an existing connection between an in-vehicle system and a wireless mobile communication device, sending a prompt to the wireless mobile communication device requesting the user to provide information regarding a dining experience at the restaurant, and receiving a response, including the information, from the wireless mobile communication device; and (c) detecting the vehicle being located near a movie theater, to which the in-vehicle system provided navigation guidance, detecting an existing connection between an in-vehicle system and a wireless mobile communication device, sending a prompt to the wireless mobile communication device requesting the user to provide information regarding a movie viewing experience at the movie theater, and receiving a response, including the information, from the wireless mobile communication device.
In some embodiments, an application may be downloaded and installed to a wireless mobile communication device. When executed by the wireless mobile communication device, the application may send information stored on the wireless mobile communication device to an in-vehicle system and/or may receive information from the in-vehicle system for storage on the wireless mobile communication device via a short-range communication link. As new types of communications may be developed for communicating between an in-vehicle system and a wireless mobile communication device, an updated application may be downloaded and installed to the wireless mobile communication device. In addition, when a user replaces a wireless mobile communication device with an updated wireless mobile communication device, an updated application may be downloaded and installed to the updated wireless mobile communication device, such that types of messages communicated between the in-vehicle system and a previous wireless mobile communication device, may continue to be communicated between the in-vehicle system and the updated wireless mobile communication device, as well as supporting new types of messages.

Exemplary Process
FIG. 5 is a flowchart illustrating exemplary processing in an embodiment. The process may begin with in-vehicle system 102 determining whether a triggering event has occurred (act 502). If no triggering event has occurred, then in-vehicle system 102 may continue to wait for an occurrence of a triggering event.
If a triggering event has occurred, then in-vehicle system 102 may call process 600 (act 504), call process 800 (act 505), call process 900 (act 506), or call process 1000 (act 508), depending upon a type of triggering event detected.
FIG. 6 illustrates exemplary processing with respect to process 600. The process may begin with in-vehicle system 102 determining whether a connection exists with wireless mobile communication device 104 (act 604).
FIG. 7 is a flowchart illustrating act 604. The process may begin with in-vehicle system 102 determining whether a pairing relationship exists between the in-vehicle system 102 and wireless mobile communication device 104 (act 702). The pairing relationship may use Bluetooth® technology in some embodiments. If the pairing relationship is determined to exist, then an indication may be returned indicating that a connection exists (act 704). Otherwise, an indication may be returned indicating that a connection does not exist (act 706).
Returning to FIG. 6, if no connection is determined to exist with wireless mobile communication device 104, then in-vehicle system 102 may determine whether a maximum waiting time has passed (act 606). The maximum waiting time may be 60 seconds or another suitable time period. If the maximum waiting time has passed, then in-vehicle system 102 may wait a pre-determined amount of time, such as, for example, 10 seconds, or another suitable time period before performing act 604 again.
If, during act 606, in-vehicle system 102 determines that the maximum waiting time has passed, then in-vehicle system 102 may simply cause control to be returned to a calling program and processing with respect to the triggering event may be discarded.
If, during act 604, in-vehicle system 102 determines that a connection exists with wireless mobile communications device 104, then in-vehicle system 102 may wirelessly send a prompt, via short-range communication module 306, to wireless communication device 104 requesting information from a user (act 610). Wireless mobile communication device 104 may receive the prompt and may present the prompt on a display of wireless communication device 104 (act 612). In some embodiments, the prompt may be presented in a pop-up style on the display. The displayed prompt may include one or more areas for the user to provide requested information. Wireless mobile communication device 104 may receive the requested information from the user and may send the requested information to in-vehicle system 102 via short-range communication link 106 (act 614).
In-vehicle system 102 may receive the response from wireless mobile communication device 104 via short-range communication link 106 (act 616). Next, in-vehicle system 102 may provide information for obtaining additional information to wireless mobile communication device 104 (act 620). The additional information may be in the form of a business review, an advertisement and/or an electronic coupon. Wireless mobile communication device 104 may then obtain the additional information (act 622). In some embodiments, wireless mobile communication device 104 may obtain the additional information from server 110. In other embodiments, wireless mobile communication device 104 may obtain the additional information from other sources.
Wireless mobile communication device 104 may store the additional information, such that the additional information may not be altered by the user. Eventually, act 502 may again be performed to detect, or wait for, an occurrence of a next triggering event.
Returning to FIG. 5, if the detected triggering event is of a second type, then in-vehicle system 102 may call process 800. In some embodiments, the second type of triggering event includes a vehicle ignition switch on event.
FIG. 8 is a flowchart illustrating exemplary processing with respect to a detected occurrence of the second type of triggering event. The process may begin with in-vehicle system 102 determining whether a connection exists between in vehicle system 102 and wireless mobile communication device 104 (act 802). In various embodiments, processing with respect to act 802 may be identical to the exemplary processing illustrated in FIG. 7.
If in-vehicle system 102 determines that a connection with a wireless mobile communication device 104 exists, via short-range communication link 106, then in-vehicle system 102 may send second information to wireless mobile communication device 104 via short-range communication link 106 (act 804). In some embodiments, second information may include vehicle status information. Vehicle status information may include a current odometer reading, a trip odometer reading, average miles per gallon, average speed, estimated distance until refueling, estimated oil life, last maintenance date, last maintenance odometer reading, tire pressure, next maintenance odometer reading, dealer information, interior lighting settings, and/or door lock settings, as well as other vehicle status information. The above-listed examples of vehicle status information are only exemplary. In other embodiments, actual vehicle status information may vary from the above.
Wireless mobile communication device 104 may receive the second information and may store the second information (act 806) and/or may send the second information to a remote processor, such as, for example, server 110 or another remote processor (act 808).
If, during act 802, in-vehicle system 102 determines that a short-range connection between in-vehicle system 102 and wireless mobile communication device 104 does not exist, then in-vehicle system 102 may determine whether a maximum amount of time has passed, such as, for example, 60 seconds, or another suitable time period (act 810). If the maximum amount of time has passed, then in-vehicle system 102 may cause control to return to a calling program. Otherwise, in-vehicle system 102 may wait a predetermined amount of time, such as, for example, 10 seconds, or another suitable time period (act 812) before again performing act 802.
Returning to FIG. 5, when a third type of triggering event is detected, in-vehicle system 102 may call process 900 (act 506).
FIG. 9 illustrates is a flowchart illustrating exemplary processing with respect to a detected occurrence of a third type of triggering event. The process may begin with in-vehicle system 102 determining whether a short-range communication connection exists between in vehicle system 102 and wireless mobile communication device 104 (act 902). In various embodiments, processing with respect to act 902 may be identical to the exemplary processing illustrated in FIG. 7.
If, during act 902, in-vehicle system 102 determines that a short-range communication connection between in-vehicle system 102 and wireless mobile communication device 104 exists, then in-vehicle system 102 may send an indication of an occurrence of a third triggering event to a wireless mobile communication device 104 via the short-range communication connection (act 904). Wireless mobile communication device 104 may receive the indication via the short-range communication connection (act 906) and may send information to in-vehicle system 102 (act 908).
In one embodiment, the third type of triggering event may be a vehicle ignition switch on event and in-vehicle system 102 may inform wireless mobile communication device 104 of an occurrence of the vehicle ignition switch on event. Upon being notified of the occurrence of the vehicle ignition switch on event, wireless mobile communication device 104 may send information to in vehicle system 102, such as, for example, vehicle status information, or another type of information.
Returning to a FIG. 5, when a fourth type of triggering event is detected, in-vehicle system 102 may call process 1000 (act 508).
FIG. 10 is a flowchart illustrating exemplary processing with respect to a detected occurrence of a fourth type of triggering event. The process may begin with in-vehicle system 102 determining whether a short-range communication connection exists between in-vehicle system 102 and wireless mobile communication device 104 (act 1002). In various embodiments, processing with respect to act 1002 may be identical to the exemplary processing illustrated in FIG. 7.
If, during act 1002, in-vehicle system 102 determines that a short-range communication connection between in-vehicle system 102 and wireless mobile communication device 104 exists, then in-vehicle system 102 may send a notification to wireless mobile communication device 104 (act 1004). The notification may include information such as, “vehicle lights left on”, or another notification. Wireless mobile communication device 104 may then display the notification on a display screen.
The above-described processes are only exemplary. For example, the above exemplary processes discuss four types of triggering events. However, in other embodiments, fewer than four types of triggering events, or more than four types of triggering events may be defined.
Further, in an embodiment in which wireless mobile communication device 104 receives and stores an electronic coupon, the electronic coupon may be redeemed in a number of different ways. For example, the electronic coupon may be displayed on the display of wireless mobile communication device 104 and presented to a merchant. The merchant may honor the electronic coupon and may enter a specific code on wireless mobile communication device 104 to either delete the electronic coupon or indicate redemption of the electronic coupon. In another embodiment, the electronic coupon may be sent to a merchant's device, either via infrared light transmissions, via a physical connection with the merchant device, or via another transmission means. Upon completion of sending of electronic coupon to the merchant's device, wireless mobile communication device 104 may delete the electronic coupon.
Destination Information Sharing
In one embodiment, the in-vehicle system 102 includes a navigation system that provides navigation features such as maps, turn-by-turn directions, points-of-interest (POIs), and other conventional navigation features. A problem with conventional navigation systems is that they are only useful up until the point when the user parks and exits the vehicle. However, the user's final destination is often still a substantial distance from the parking spot. A conventional vehicle navigation system cannot provide further assistance to the user in navigating from the parked vehicle to the final destination. Instead, once on foot, the user would have to resort to other techniques, such as, for example, performing a visual search, utilizing an information center or kiosk, viewing printed information or using a separate navigation application executing on a mobile device.
One embodiment of the in-vehicle system 102 solves the problem mentioned above by automatically sharing destination information with the mobile communication device 104. When a user parks the vehicle while navigating to a destination, the vehicle senses a trigger event, such as, for example, vehicle ignition shut off. This event triggers the transfer of destination information from the in-vehicle system 102 to the mobile communication device 104 via the short-range communication link 106. The mobile communication device 104 then provides remaining navigation instructions to guide the user the rest of the way to the destination by foot.
FIG. 11 is a flowchart illustrating processes performed by the in-vehicle system 102 and the mobile communication device 104 for destination sharing. While navigating to a desired destination, the in-vehicle system 102 detects 1102 a trigger event indicating that the vehicle is parked. For example, the trigger event may comprise turning off the vehicle ignition, closing or locking the driver side door, or a combination of events. Assuming that the current location is still at least a minimum distance from the desired destination, the in-vehicle system 102 alerts 1104 the user that the destination has not yet been reached (e.g., via a visual and/or audible alert). The vehicle system 102 then determines 1106 whether or not to transfer the destination information to the mobile communication device 104. In one embodiment, for example, the in-vehicle system 102 prompts the user on the in-vehicle display as to whether or not the user would like the destination information transferred. In another embodiment, a default setting may be used. For example, in one embodiment, the decision 1106 is omitted and the in-vehicle system always performs 1110 the information transfer. In yet another embodiment, the decision 1106 depends on various factors such as, for example, the distance from where the vehicle is parked to the final destination. Thus, in one embodiment, the in-vehicle system determines a distance between the in-vehicle system and the desired destination, and determines to send the destination data to the mobile communication device 104 if the distance is greater than a lower threshold difference. In another embodiment, the in-vehicle instead determines to send the destination data to the mobile communication device 104 only if the distance is less than a upper threshold difference. In yet another embodiment, both a lower and upper threshold is used, and the information is sent only when the distance falls between the thresholds.
If the in-vehicle system 102 determines 1106 to transfer the destination information to the mobile communication device 104, the destination data is transferred 1110 from the in-vehicle system 102 to the mobile communication device 104. In a first embodiment, the transferred data includes complete navigation and destination information. For example, the destination data may include one or more of graphical map data, POI (Point-of-interest) information for the nearby area, a turn-by-turn direction list to the destination, and both the current vehicle location and the desired destination location. This embodiment is particularly advantageous for use with lower cost mobile communication devices 104 that do not have navigation capabilities. Furthermore, the embodiment is particularly advantageous when the mobile communication device 104 is not connected to a cellular network (e.g., when the mobile communication device 104 is out of range) and is therefore unable to load web-based navigation or mapping information.
In a second embodiment, the vehicle system transfers only partial destination information and relies on the mobile communication device 104 for determining the rest of the data. This embodiment is useful when the mobile communication device 104 is equipped with an internal mapping and navigation system and the in-vehicle system can therefore reduce the amount of data transferred. For example, in one embodiment, the partial destination information may include only the desired destination location, because the mobile communication device 104 can determine the current location, POIs, turn-by-turn directions, etc. using its own internal navigation application. In another embodiment, the partial destination data may include only the current vehicle location, the desired destination location, and any relevant POIs located nearby. Additional information and guidance would be the responsibility of the mobile communication device 104 and its service connection. In one embodiment, the destination information may include a flag that indicates that the mobile device 104 should automatically display the navigation instructions upon receipt of the information. In yet another embodiment, the destination information can be determined based on a user setting in which the user may custom define what elements to include in the destination information transfer. Furthermore, in one embodiment, the information may be dependent on other factors such as, for example, the user's distance to the desired destination.
In another embodiment, the destination information may include other relevant information related to the desired destination or nearby POIs. For example, in one embodiment, the destination information may include coupons usable at the desired location or a nearby POI.
If the in-vehicle system 102 instead determines 1106 not to transfer the destination information to the mobile communication device 104, the in-vehicle system 102 performs 1108 a background information transfer. In one embodiment, the background information includes different information than the full destination data. For example, the background information could comprise only a subset of the transferred elements discussed above. For example, in one embodiment, the background transfer could include just the vehicle location. In another embodiment, the background transfer may transfer the same information as in the destination data transfer, but changes a flag so that the mobile device 104 does not automatically display the navigation instructions. This would allow, for example, the user to later manually launch the application at a later time and still receive navigation instructions. In yet another embodiment, the background information can be determined based on a user setting in which the user may custom define what elements to include in the background transfer or the information may be dependent on other factors such as, for example, the user's distance to the desired location.
The mobile communication device 104 receives 1112 the destination data transferred from the in-vehicle system 102. The mobile communication device 104 prompts 1114 the user as to whether or not the user would like to continue to the destination (e.g., a visual or audible prompt) and receives 1116 the user's decision. If the user selects not to continue the destination, the destination data is cached 1118 and may be used later should the user later decide to utilize it. Thus, for example, if the user later requests the navigation instructions, the mobile communication device retrieves the stored destination data and displays the navigation instructions. If the user selects to continue to the destination, the mobile communication device 104 provides 1120 destination information. In one embodiment, where complete destination data is transferred, the mobile communication device 104 is responsible only for displaying the received information, and optionally, the current location. No external data needs to be pulled from external sources. In another embodiment, where partial destination data is transferred, the mobile communication device 104 opens its navigation or mapping application and inputs the coordinates of the desired destination. The mobile communication device 104 then provides navigation guidance to the destination including, for example, a map, turn-by-turn walking (or public transportation) directions, and points-of-interest in the vicinity. In yet other embodiment, the information may include a menu that allows the user to select options to navigate to the destination or access coupons usable at the desired destination or POIs. In one embodiment, destination information such as navigation instructions, coupons, or other information may be automatically displayed only when the user gets within a certain distance of the desired destination.
CONCLUSION
Although the subject matter has been described in language specific to structural features and/or methodological acts, it is to be understood that the subject matter in the appended claims is not necessarily limited to the specific features or acts described above. Rather, the specific features and acts described above are disclosed as example forms for implementing the claims.
Although the above descriptions may contain specific details, they are not to be construed as limiting the claims in any way. Other configurations of the described embodiments are part of the scope of this disclosure. In addition, acts illustrated by the flowcharts of FIGS. 5-10 may be performed in a different order in other embodiments, and may include additional or fewer acts. For example, in some embodiments, instead of detecting a triggering event and then determining that a short-range communication connection with a wireless mobile communication device exists before communicating with the wireless mobile communication device, an in-vehicle system, instead, may detect an occurrence of a triggering event only when the short-range connection is determined to exist. Further, in other embodiments, other devices or components may perform portions of the acts described above. Accordingly, the appended claims and their legal equivalents define the invention, rather than any specific examples given.
