Accelerometer and voltage based key-on and key-off detection
First Claim
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;
initiating, by the device, communications with the vehicle diagnostic system to obtain first vehicle data based on determining the key-on status;
receiving the first vehicle data based on initiating the communications with the vehicle diagnostic system;
validating the key-on status if the first vehicle data received from the vehicle diagnostic system indicates the engine of the vehicle is powered on; and
receiving second vehicle data, different than the first vehicle data, from the vehicle diagnostic system based on validating the key-on status.

Abstract
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.

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; initiating, by the device, communications with the vehicle diagnostic system to obtain first vehicle data based on determining the key-on status; receiving the first vehicle data based on initiating the communications with the vehicle diagnostic system; validating the key-on status if the first vehicle data received from the vehicle diagnostic system indicates the engine of the vehicle is powered on; and receiving second vehicle data, different than the first vehicle data, from the vehicle diagnostic system based on validating the key-on status. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12)

13. A device comprising:
one or more processors to; receive accelerometer measurements associated with a vehicle; receive voltage measurements associated with a power source connected to the vehicle; determine 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; initiate communications with the vehicle diagnostic system to obtain first vehicle information based on determining the key-on status; receive the first vehicle information based on initiating the communications with the vehicle diagnostic system; validate the key-on status if the first vehicle information received from the vehicle diagnostic system indicates the engine of the vehicle is powered on; and receive second vehicle information, different than the first vehicle information, from the vehicle diagnostic system based on validating the key-on status. - View Dependent Claims (14, 15, 16, 17)

18. A non-transitory computer-readable medium for storing instructions, the instructions comprising:
a plurality of instructions which, when executed by one or more processors associated with a device, cause the one or more processors to; receive accelerometer measurements associated with a vehicle; receive voltage measurements associated with a power source connected to the vehicle; determine a key-on status or a key-off status of the vehicle based on the accelerometer measurements or the voltage measurements independent of 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; initiate communications with the vehicle diagnostic system to obtain first vehicle information based on determining the key-on status; receive the first vehicle information based on initiating the communications with the vehicle diagnostic system; validate the key-on status if the first vehicle information received from the vehicle diagnostic system indicates the engine of the vehicle is powered on; and receive second vehicle information, different than the first vehicle information, from the vehicle diagnostic system based on validating the key-on status.
