Abstract

In a brake-by-wire vehicle brake system that uses a solenoid shut-off valve (), the electric power supplied to the solenoid () of the solenoid shut-off valve is controlled so as to decelerate a movement of a plunger () of the valve as the plunger reaches a point immediately adjacent to a terminal point thereof. Thereby, a highly responsive property can be achieved while the noises that are generated by the plunger striking a stopper () or a valve seat () can be minimized. When actuating the plunger in the valve closing direction, the solenoid may receive electric power at a first level, a second level lower than the first level and a third level intermediate between the first and second levels in that order.
