  • Failure check apparatus for control apparatus of vehicle
    Patent number: 7306296
    Abstract: A failure check apparatus for a control apparatus of a vehicle such as ABS. When the failure check apparatus performs initial check for the ABS, it successively activates each of solenoid valves and a motor provided in the ABS, one at a time, for a predetermined time so as to determine whether a failure has occurred in the ABS. At that time, activation of the motor is started when a certain delay time elapses after the end of activation of the last solenoid valve. The delay time is a time which the vibration generated in the control apparatus upon activation of the last solenoid valve converges. Thus, interference between a vibration wave (sound wave) generated upon actuation of the solenoid valves and a vibration wave (sound wave) generated upon actuation of the motor, which differ in nature of vibration, is prevented.
