摘要： A highly reliable vehicle brake system including an electric brake is provided.
A vehicle brake system (1) includes electric brakes (16a to 16d) provided with motors (80 to 85), drivers (60 to 65) that drive the motors (80 to 85), and a control device that controls the drivers (60 to 65). The electric brake (16a) includes two motors (80 and 81), and the control device includes separate drivers (60 and 61) respectively corresponding to the two motors (80 and 81). The control device includes a first master controller (30) and a first sub-controller (40). The first master controller (30) controls the driver (61) corresponding to the motor (81), and the first sub-controller (40) controls the driver (60) corresponding to the motor 80.-

摘要： In an electric parking brake device configured in such a way that a parking brake state resulting from pulling of a brake cable is released by loosening the brake cable, the brake cable is formed by twisting together a plurality of wires in such a way as to generate a twisting force in a fixed direction when pulled, and the direction in which the twisting force generated by the brake cable in a pulled state acts on a screw shaft is set to be the same direction as the direction in which a nut is rotated to loosen the brake cable. This makes it possible to reduce an operating sound and to reduce wear of members constituting a rotation restricting device.

摘要： In an electric parking brake device in which a parking brake state is released by loosening a brake cable: a nut is screwed onto a screw shaft in such a way as to be capable of moving in an axial direction; a movement restricting portion which is caused to abut the screw shaft or a linked member that moves in the axial direction together with the screw shaft, thereby restricting an axial direction movement end of the screw shaft to the side loosening the brake cable, is disposed in a fixed position inside an actuator case; and a resilient member which is compressed in response to axial direction movement of the nut after movement restriction has been effected by the movement restricting portion when the screw shaft moves in the axial direction toward the side loosening the brake cable is interposed between the nut and an insertion member.

摘要： A brake fluid pressure control device for a vehicle includes a wheel speed acquisition device that acquires a wheel speed, an estimated vehicle body speed calculation device that calculates an estimated vehicle body speed on the basis of the wheel speed, and a bad road determination device that determines whether a road surface of travel is a bad road. The brake fluid pressure control device for a vehicle can provide hydraulic control of a brake fluid that is used in wheel brakes, and the bad road determination device determines whether the road surface of travel is a bad road on the basis of the deviation between the estimated vehicle body speed and the wheel speed. The present invention can detect phenomena particular to bad roads, and can more accurately perform bad road determination, and allows for the improvement of control such as ABS control.
