Abstract: If the temperature (Tig) of a switching element (25) in a source power supply circuit (24) of an electric motor (2) increases to be equal to or greater than a first predetermined value (?) while an electric vehicle (1) is in a stall state, a torque command for the electric motor (2) is reduced while a braking force command for a brake unit (10) is increased, and if the temperature (Tig) of the switching element (25) subsequently decreases to be equal to or less than a second predetermined value (?(<?)), the braking force command for the brake unit (10) is decreased while the torque command for the electric motor (2) is increased. The increment rate of the torque command for the electric motor (2) is varied in accordance with the degree of road gradient.

Abstract: In a brake-by-wire vehicle brake system using a feedback control unit (12a, 12b, 31, 36, 45) for producing a brake fluid pressure according to a brake input, a response restricting unit (26, 39, 48) restricts a response property of the feedback control unit when an extraneous brake fluid control operation is detected. Thereby, the control unit is prevented from excessively reacting to changes in the brake fluid pressure caused by the extraneous brake fluid control operation, and the vehicle brake system can provide a highly responsive property and a resistance to changes in the brake fluid pressure at the same time.

Abstract: Upon occurrence of a change in the load versus fluid loss property, the braking force for the given brake pedal operation amount is changed so that the vehicle operator is enabled to perceive the change in the load versus fluid loss property. In a vehicle brake system comprising a motor actuated cylinder, wheel cylinders, a stroke sensor for detecting a brake pedal operation amount, a target value setting circuit for setting a target stoke of the motor actuated cylinder, and a fluid pressure compensating circuit for correcting the target stoke upon detection of a deviation between a brake fluid pressure reference value corresponding to the brake pedal operation amount and an actual brake fluid pressure in a direction to reduce the deviation, a stroke limiting circuit restricts a compensation value produced by the fluid pressure compensation circuit according to the brake pedal operation amount.

Abstract: In a brake-by-wire vehicle brake system that uses a solenoid shut-off valve (24a, 24b), the electric power supplied to the solenoid (33) of the solenoid shut-off valve is controlled so as to decelerate a movement of a plunger (31, 32) 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 (36) or a valve seat (34) 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.
