Control system for vehicle, has electronic control unit comprising diagnosing device to diagnose whether self-diagnosis device is abnormal by causing input device to input signal into self-diagnosis device

摘要

The system has a brake-negative pressure sensor (46) for detecting a predetermined physical parameter and comprising an electronic control unit (40). The control unit processes an output from the sensor and controls an operation of a vehicle based on the output from the pressure sensor. The control unit comprises a diagnosing device to diagnose whether a self-diagnosis device is abnormal by causing the input device to input a signal into the self-diagnosis device. The pressure sensor comprises a detection unit to detect pressure collected in a brake force multiplication device.
