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 order to achieve a good brake feeling, a brake control system includes a master cylinder which discharges pressurized operating fluid according to an operating amount of a brake operating member by a driver, a stroke simulator which is connected to the master cylinder and creates a reaction force with respect to that operation according to the operating amount of the brake operating member, and a control portion which calculates a target deceleration using hydraulic pressure in the stroke simulator. The brake control system is also provided with a master cylinder pressure sensor that measures the hydraulic pressure in the master cylinder. The control portion may also calculate the target deceleration using an estimated value of the hydraulic pressure in the stroke simulator calculated based on the measured value from the master cylinder pressure sensor.
