Vehicle control device and vehicle control system

Abstract

Achieved is a vehicle control device capable of performing seamless automatic driving control even when an operation abnormality occurs in an operation processing unit in a vehicle control device, and improving safety. When operation processing of an actuator control command is performed by two microcomputers of microcomputersandin synchronization, and a monitoring circuitdetects an abnormality of the microcomputer, a communication circuitthat communicates the actuator control command of the microcomputerto a brake control unitor the like is latched in a disabled state, and the actuator control command from an iconis transmitted to the brake control unitor the like via the communication circuit. The disabled state of the communication circuitis maintained until an IGNSW or an automatic driving SW of the vehicle toggles, and until that time, the actuator control command from the microcomputeris transmitted to the brake control unitor the like. The control moves from the microcomputerto the microcomputerto the microcomputer, so that it is possible to suppress the occurrence of the control gap at every control transition of multiple times, and it is possible to maintain the seamless automatic driving control.
