Abstract
An electronic device for use in a vehicle and method for controlling the same are provided. The device includes a battery sensor configured to detect a battery voltage when connected to a vehicle's battery, and a processor in communication with the battery sensor. The processor is configured to monitor the battery voltage of a vehicle's battery using the battery sensor and identify at least one transition in the battery voltage. The processor is also configured to determine an operational state of the vehicle based on the transition and the battery voltage, and control the electronic device in accordance with the operational state of the vehicle.
Claims18
A method for controlling an electronic device for use in a vehicle, the method comprising:
- monitoring a battery voltage of a vehicle's battery using a battery sensor connected thereto;
- identifying at least one transition in the battery voltage using a processor in communication with the battery sensor;
- determining, using the processor, an operational state of the vehicle based on the transition and the battery voltage by:
- controlling a load circuit using the processor to apply a load to the vehicle's battery;
- and
- determining the operational state of the vehicle based on a change in the battery voltage due to the load;
- and
- controlling, using the processor, an electronic device coupled to the vehicle's battery in accordance with the operational state of the vehicle.
