Abstract
When it has been determined that a termination condition of brake TRC control has been fulfilled, SM valves 50FL and 50FR and a motor 80 are continuously placed in an ON state, and along with this, SR valves 70FL and 70FR are switched off, and furthermore holding valves 46FL and 46FR and pressure-reducing valves 48FL and 48FR of driving wheels are changed from an on-off switching state to an ON state, and termination control is initiated. Because of this, high-pressure brake fluid on the wheel-cylinder 2FL and 2FR side is expelled via the pressure-reducing valves 48FL and 48FR by drive of the motor 80. Consequently, high-pressure brake fluid can rapidly be expelled immediately after brake TRC control, and along with this, oil-shock noise can be alleviated.
