摘要： In a brake control system, a power supply portion supplies a voltage to a plurality of actuators. When a first actuator is supplied with a voltage equal to or higher than a first minimum operating voltage from the power supply portion, the first actuator operates to perform a first function. When a second actuator is supplied with a voltage equal to or higher than a second minimum operating voltage from the power supply portion, the second actuator performs a second function. The first minimum operating voltage and the second minimum operating voltage are set to be different from each other by a predetermined value so that the first actuator and the second actuator stop operating in a predetermined sequence with a decrease in the supplied voltage.

摘要： A holding valve (61) is provided on an individual flow passage (51) connecting a main flow passage (52) and a wheel cylinder (42) to each other. The holding valve (61) permits communication between an upstream side and a downstream side in an open state to transmit the hydraulic pressure from an accumulator (32) to the wheel cylinder (42), and shuts off the communication between the upstream side and the downstream side in a closed state. Moreover, a pressure reducing valve (62) for realizing communication or shutoff between a reservoir (22) and a main flow passage (52) and between the reservoir (22) and the wheel cylinder (42) is provided on a pressure reducing individual flow passage (56) for connecting a reservoir flow passage (57) and the individual flow passage (51) to each other. Then, when a driver carries out a return operation on a brake pedal (10) during antiskid control, a brake ECU (100) inhibits the holding valve (61) in the closed state from shifting to the open state, maintains the holding valve (61) in the open state, and controls the pressure reducing valve (62) corresponding to this holding valve (61) to shift to the open state. As a result, a hydraulic pressure in the main flow passage (52) is decreased via the holding valve (61) and the pressure reducing valve (62) in the open state.

摘要： In a braking control apparatus, a plurality of pumps are driven by a common first motor. A brake supplies operating fluid to pipelines by operating the first motor, and controls opening/closing of a fluid pressure regulating valve so as to make the wheel cylinder pressure in the right front wheel approach the right front wheel target pressure, and controls opening closing of a fluid pressure regulating valve so as to make the wheel cylinder pressure in the left rear wheel approach the left rear wheel target pressure. In the case where the right front wheel target pressure is zero when the fluid pressure regulating valve is to be opened so as to make the wheel cylinder pressure in the left rear wheel approach the left rear wheel target pressure, the brake turns off the first motor.

摘要： A brake control system includes a wheel cylinder, a brake pedal, a master cylinder in which communication between it and an external master cylinder reservoir is cut off when the operating amount of the brake pedal is equal to or greater than a predetermined value, an internal reservoir, and a pump which selectively discharges hydraulic fluid in two directions, one being a direction that increases the hydraulic pressure in the wheel cylinder by drawing up hydraulic fluid from the internal reservoir, and the other being a direction that stores hydraulic fluid in the internal reservoir. The pump is driven to discharge hydraulic fluid in the direction that stores hydraulic fluid when communication is open between the master cylinder and the master cylinder reservoir, and driven to discharge hydraulic fluid in the direction that increases the hydraulic pressure when communication is cut off between the master cylinder and the master cylinder reservoir. A further invention is directed to a brake control method.

摘要： An apparatus that generates brake pedal reaction force is provided. The apparatus includes a variable throttle mechanism that varies a fluid passage area between the variable throttle mechanism and a stroke simulator when the flow rate of an operating fluid supplied from a master cylinder exceeds a predetermined flow rate. The variable throttle mechanism includes a movable member, in which a through passage for the operating fluid is formed, and a throttle portion that is formed in the middle of the through passage. The movable member is slidably provided in the inside of a case body and the movable member changes the fluid passage area by closing a portion of a communicating port formed in the case body.
