Abstract
The purpose of the present invention is to provide a system in which the reliability of an automatic driving system can be excellently complemented by a different control system while the automatic driving system is effectively used. The vehicle control device outputs to a drive device one of a first control signal generated on the basis of automatic driving control information, and a second control signal generated on the basis of the relative information between a vehicle and a surrounding object. If an abnormality is detected in the automatic driving control information, the second control signal is output to the drive device in place of the first control signal.
Claims12
A vehicle control device comprising:
- at least a first electronic control unit, the first electronic control units includes
- a processor, an input/output device, a timer, a ROM and a RAM each communicatively coupled;
- at least one actuator;
- and
- a plurality of sensors, the plurality of sensors are communicatively coupled to the first electronic control units and the at least one actuator via a gateway that connects multiple network links,
- wherein the processor receives, via the input/output device, an input of a first control signal generated based on automatic driving control information from the plurality of sensors,
- wherein the processor outputs a second control signal generated based on relative information between a host vehicle and a surrounding object from the plurality of sensors,
- wherein the processor analyzes the first control signal and determines if there is a malfunction within the vehicle control device based on the automatic driving control information, and in a case where the malfunction is detected outputs the second control signal to the actuator instead of outputting the first control signal.
