Vehicle control device

1 . A vehicle control device mounted in a vehicle, the vehicle control device comprising:

a first processor configured to:

determine whether a steering angle of a steering wheel and a turning angle of a steered wheel are in a synchronous state; and

determine whether the vehicle is in a travelable state;

a second processor configured to:

transmit, to the first processor, a multiplex communication signal indicating that the vehicle is in a non-travelable condition until a start-up requesting signal is received from the first processor; and

transmit, to the first processor, a multiplex communication signal indicating that the vehicle is in the travelable state in response to receiving the start request signal from the first processor and completing a predetermined process for traveling;

a power supply unit; and

an ignition relay provided between the power supply unit and the second processor,

wherein the first processor is configured to stop a power supply from the power supply unit to the second processor by shutting off the ignition relay in a case where the first processor determines that the steering angle and the turning angle are not in the synchronous state and determines that the vehicle is in the travelable state.

2 . The vehicle control device according to claim 1 , wherein in a case where the first processor determines that the steering angle and the turning angle are not in the synchronous state and determines that the travelable state of the vehicle continues for a predetermined time, the first processor shuts off the ignition relay.

3 . The vehicle control device according to claim 1 , wherein the first processor is configured to determine that the steering angle and the turning angle are in the synchronous state by receiving a synchronization completion signal from both a second device that controls the steering wheel and a third device that controls the steered wheel.
