Abstract
A vehicle brake device A is provided with a master cylinder, a reservoir tank, solenoid valvesandfor adjustably draining brake oil from outlet portsof the master cylinderto the reservoir tank, a collision detection sensorfor detecting a collision of the vehicle, a fluid pressure meterfor detecting the master cylinder pressure, and an ECU. The ECUdetects the pushing-up of the brake pedalbased on the occurrence of a collision and the master cylinder pressure, and upon detection of the pushing-up, controls the solenoid valvesandto adjust the draining of the brake oil so that the brake pedalis withdrawn. Thus, a time point when the brake pedalbegins to be pushed up by the cause of the vehicle collision can be detected accurately and reliably, and the brake pedalcan be withdrawn accurately in dependence on the pushing-up. This reliably secures an anchorage upon which the driver keeps his body balance and reliably prevents an excess load from being exerted on the driver.
