ACCELEROMETER AND VOLTAGE BASED KEY-ON AND KEY-OFF DETECTION

摘要

A device may receive a first type of measurement associated with a vehicle and receive a second type of measurement associated with a power source connected to the vehicle. The second type of measurement may be different than the first type of measurement. The device may determine a key-on or a key-off status of the vehicle based on the first type of measurement and the second type of measurement without communicating with a vehicle diagnostic system associated with the vehicle. The key-off status may correspond to an engine of the vehicle being powered off and the key-on status may correspond to the engine of the vehicle being powered on. The device may initiate communications with the vehicle diagnostic system based on determining the key-on status.

主权项

1. A method comprising:
receiving, by a device, accelerometer measurements associated with a vehicle; receiving, by the device, voltage measurements associated with a power source connected to the vehicle; determining, by the device, a key-on status or a key-off status of the vehicle based on the accelerometer measurements or the voltage measurements without communicating with a vehicle diagnostic system associated with the vehicle,
the key-off status corresponding to an engine of the vehicle being powered off, and the key-on status corresponding to the engine of the vehicle being powered on; and initiating, by the device, communications with the vehicle diagnostic system based on determining the key-on status.
