Abstract
When a vacuum booster fails, an pressure amplifying mechanism increases a wheel brake pressure. After that, even when it is detected that the vehicle is brought into a stopped state, the state in which an increased brake fluid pressure is applied to wheel cylinders is held. If a condition for terminating control to maintain a stationary state of the vehicle is satisfied, that is, if a predetermined time period has elapsed since when the vehicle stops, the operation of the pressure amplifying mechanism is stopped to reduce the wheel cylinder pressure.
