摘要： When an electrical fluid pressure generator fails and a wheel cylinder is operated by brake fluid pressure generated by a master cylinder, if a first fluid pressure system leading to a rear fluid chamber of the electrical fluid pressure generator fails and is opened to the atmosphere, braking is performed by brake fluid pressure of a second fluid pressure system transmitted from the master cylinder through a front fluid chamber of the electrical fluid pressure generator to a wheel cylinder. At this time, a front supply port, which communicates through a front second cup seal, does not communicate with the master cylinder but with a reservoir. Such configuration prevents leakage of the brake fluid pressure generated by the master cylinder through the front supply port, the front second cup seal and the rear fluid chamber, thereby ensuring braking by the second fluid pressure system.

摘要： A VSA device (24), which controls vehicle behavior by individually controlling the pressure of brake fluid supplied from a slave cylinder (23) to a wheel cylinder (16, 17; 20, 23), is provided with: an accumulator (62) which can be connected to the wheel cylinder and the slave cylinder (23); an out-valve (60, 61) disposed on a fluid path between the wheel cylinder and the accumulator (62); a check valve (63) that allows only flow of brake fluid from the accumulator (62) to the slave cylinder (23); and a regulator valve (54) disposed on a fluid path between the wheel cylinder and a path between the check valve (63) and the slave cylinder (23). Brake fluid is discharged from the accumulator (62) to the slave cylinder (23) by reducing the driving force of an electric motor (32) of the slave cylinder (23), thereby rendering a special pump unnecessary and making it possible to reduce the weight, cost, and component count.

摘要： When brake fluid of a first wheel cylinder (39a) of a slave cylinder (23) is increased by supplying the brake fluid to a first wheel cylinder (16, 17) by a first pump (64A), a second piston (38B), which is a free piston, of the slave cylinder (23) moves toward the first fluid pressure chamber (39A) side, the volume of a second fluid pressure chamber (39B) thereby expands, and the brake fluid pressure of a second wheel cylinder (20, 21) can be reduced, whereas when brake fluid pressure of the second fluid pressure chamber (39B) is increased by supplying the brake fluid to the second wheel cylinder (20, 21) by a second pump (64B), the second piston (38B) moves toward the second fluid pressure chamber (39B) side, the volume of the first fluid pressure chamber (39A) thereby expands, and the brake fluid pressure of the first wheel cylinder (16, 17) can be reduced, thus enabling a difference in brake fluid pressure to be freely generated between the first and second wheel cylinders (16, 17).

摘要： During normal operation of a braking force generating device, the wheels are braked by braking force generating device when a depressing force cut-off valve is closed by energizing its solenoid to cut off communication between a master cylinder and wheel cylinders. When an abnormality occurs, a master cylinder generates a brake fluid pressure upon a driver's braking operation, and supplies it to the wheel cylinders when the depressing force cut-off valve is opened by de-energizing its solenoid. When the depressing force cut-off valve is closed, such as during normal operation, since the depressing force cut-off valve functions as a one-way valve that is urged in a valve-closing direction due to a brake fluid pressure generated by the master cylinder, an electromagnetic force generated by the solenoid is smaller, thereby reducing the power consumption of the solenoid.

摘要： Systems and methods to prevent dragging of a fluid pressure type disk brake system are described herein. Brake fluid pressure generated by a master cylinder during a braking operation is transmitted to a wheel cylinder via a VSA system. The VSA system includes a low pressure accumulator and an out-valve disposed between the wheel cylinder and the low pressure accumulator. Temporarily opening the out-valve during a braking operation allows part of the brake fluid that would otherwise be supplied to the wheel cylinder to be supplied to the low pressure accumulator. After the braking operation by the driver is completed, brake fluid supplied to the wheel cylinder is returned to the master cylinder. Thus, a piston of the wheel cylinder is withdrawn by an extra amount corresponding to the amount of brake fluid supplied to the low pressure accumulator, thus reliably prevents disk pad dragging in the disk brake system.

摘要： A brake system includes a master cylinder which generates brake fluid pressure by a braking operation of a driver, an electric motor driven slave cylinder that generates brake fluid pressure according to an electrical signal based on the braking operation of the driver, a vehicle wheel cylinder for braking a wheel by the brake fluid pressure generated in the master cylinder or the slave cylinder, a brake light that informs a following vehicle of the operation of the wheel cylinder, and a first sensor and a second sensor that detect stroke positions of the brake pedal. During normal operation of the brake system the brake fluid pressure generated in the slave cylinder is transferred to the wheel cylinder. During abnormal operation of the brake system, the brake fluid pressure generated in the master cylinder is transferred to the wheel cylinder. Further, the first sensor activates the brake light when the slave cylinder operates normally, and the second sensor activates the brake light when the slave cylinder does not operate normally.

摘要： A BBW type brake system which operates fluid pressure generators having electric motors as drive sources based on an electrical signal to brake a wheel, field weakening control of the electric motors is performed in the initial stage of operation of the fluid pressure generators to increase the rotational speed of the electric motors. Therefore, it is possible to reduce a time lag before the braking force actually generates after the electrical signal for operating the fluid pressure generators is outputted, thereby improving operational responsiveness. After the braking force actually generates, the field weakening control is cancelled to secure a required braking force with a sufficient torque.
