VEHICLE CONTROL APPARATUS AND VEHICLE CONTROL SYSTEM

WIPO Patent Application WO/2018/225352

A1

The present invention achieves a vehicle control apparatus capable of seamless autonomous driving control and improved safety even in the event of an operational anomaly in a calculation processing unit of the vehicle control apparatus. Two microcomputers 11b and 12b synchronously execute a process to calculate an actuator control command. A monitoring circuit 11m, on detecting an anomaly in the microcomputer 11b, latches to the disabled state a communication circuit 11c for communicating the actuator control command from the microcomputer 11b to a brake control unit 13 or the like, and transmits to the brake control unit 13 or the like via a communication circuit 12c the actuator control command from the microcomputer 12b. The disabled state of the communication circuit 11c is maintained until the ignition switch or autonomous driving switch of the vehicle is toggled, and until then, the actuator control command from the microcomputer 12b is transmitted to the brake control unit 13 or the like. Control shifts from the microcomputer 11b to the microcomputer 12b and then to the microcomputer 11b, the emergence of a gap in control can be controlled against during each of the multiple transitions of control, enabling seamless automatic operation control to be maintained.
