Abstract: Methods and apparatus to adjust an advertising rate of a device to reduce battery usage are described herein. An example method includes determining a distance of a device from a vehicle based on a signal, determining a state of motion of the device, and adjusting an advertising rate of the signal based on the distance and state of motion.

Abstract: A memory stores telemetry data for a vehicle. A processor is programmed to send an authorization confirmation request to the vehicle responsive to pattern matching on the telemetry data indicating a potential change in authorization of the vehicle, and send a deauthorization request to an authorization server to deauthorize tokens for the vehicle responsive to a lack of an affirmative response to the authorization confirmation request being received within a predefined time period.

Abstract: Methods and apparatus are disclosed for authentication of mobile devices for vehicle communication. An example mobile device for vehicle communication authentication a communication module to receive a signal from a vehicle, memory including an application for accessing digital keys, and key accessor. The example key accessor is to activate, in response to determining the application is inactive, the application utilizing the signal. The example key accessor also is to access a key via the application and send, via the communication module, the key to the vehicle.

Abstract: Method and apparatus are disclosed for priming vehicle access based on wireless key velocity. An example vehicle includes a communication module to receive a signal from a wireless key of a user that includes velocity data of the wireless key and determine a distance to the wireless key. The example vehicle also includes a vehicle primer to determine an arrival time of the user based on the velocity data and the distance and prime the vehicle for access before the arrival time.

Abstract: A system includes a processor configured to access a map, including pre-designated destinations, each destination having a clue associated therewith. The processor is also configured to provide the clue associated with a first destination. The processor is further configured to track the progress of a user towards the first destination using GPS coordinates. Also, the processor is configured to provide a clue associated with a next destination, once the user has reached the first destination. Further, the processor is configured to repeat map access, clue provision, and tracking until the user has reached a pre-designated final destination.
