Abstract
The present disclosure includes device controllers that output control signals to in-vehicle devices based on a target motion set by a target motion setter based on input from the sensors, and a device failure diagnostic unit provided between the device controllers and the in-vehicle devices in a communication path of an arithmetic unit, in which the device failure diagnostic unit has a device diagnostic table in which the in-vehicle devices associated with each function are specified for each function of the vehicle, and diagnoses a failure of the in-vehicle devices based on output of the in-vehicle devices and the device diagnostic table.
Claims8
A vehicle failure diagnostic device comprising:
- an arithmetic unit configured to perform a calculation for controlling in-vehicle devices mounted in a vehicle;
- a plurality of sensors configured to input vehicle information including an exterior environment of the vehicle to the arithmetic unit;
- a target motion setter provided in the arithmetic unit and configured to set a target motion of the vehicle based on the information input by the plurality of the sensors;
- a device controller provided in the arithmetic unit and configured to output a control signal to each of the in-vehicle devices based on the target motion set by the target motion setter;
- and
- a device failure diagnostic unit provided between the device controller and the in-vehicle devices in a communication path of the arithmetic unit and configured to diagnose a failure of each of the in-vehicle devices,
- the device failure diagnostic unit having a device diagnostic table in which the in-vehicle devices associated with each function are specified for each function of the vehicle, and diagnosing the failure of the in-vehicle devices based on output of the in-vehicle devices and the device diagnostic table.
