摘要： A brake control device includes: a braking-effort-sensing device for sensing braking efforts of vehicle wheels; an actuator for applying braking efforts to the vehicle wheels; and a control device for controlling the braking efforts of the vehicle wheels by controlling the actuator, wherein the control device: computes desired braking efforts of the vehicle wheels; and when the desired braking efforts of left and right wheels of the vehicle wheels are equal to each other. The brake control device performs a braking effort correction of allowing the braking effort of one of the left and right wheels to approach the braking effort of the other of the left and right wheels.

摘要： A brake control apparatus of an automotive vehicle employs a pump incorporated in a hydraulic actuator, a separate pressure control valve disposed between the pump and each individual wheel-brake cylinder and having an orifice having a predetermined orifice-constriction flow passage area, and vehicle sensors including at least wheel cylinder pressure sensors. Also provided is a controller configured to be connected to the vehicle sensors and the hydraulic actuator, for calculating, based on a driver's manipulated variable, target wheel cylinder pressures, and for controlling the hydraulic actuator responsively to the target wheel cylinder pressures. The controller is further configured for calculating a fluid-pressure deviation between the target wheel cylinder pressure and the actual wheel cylinder pressure, and for stopping working-fluid supply from the pump to the abnormal wheel-brake cylinder having an abnormality in the fluid-pressure deviation exceeding a predetermined threshold value.

摘要： In a brake control system for a vehicle employing a brake-by-wire (BBW) hydraulic control unit, a master cylinder serves as a first fluid pressure source and a pump serves as a second fluid pressure source operated during a BBW system normal brake operating mode. Also provided is a manual-brake hydraulic circuit capable of supplying hydraulic pressure from the master cylinder to the wheel-brake cylinder during a fail-safe operating mode. A back-flow prevention device is disposed in a pump outlet passage, intercommunicating the manual-brake hydraulic circuit and the pump outlet, for permitting free flow in one direction from the pump to the wheel cylinder. A normally-open inflow valve is disposed in the pump outlet passage downstream of the back-flow prevention device. A normally-open shutoff valve is disposed in the manual-brake hydraulic circuit upstream of the normally-open inflow valve, and unactuated and opened during the fail-safe operating mode.
