摘要： A hydraulic brake system includes: a hydraulic pressure source provided for a vehicle, and including a hydraulic-pressure generating device and a reservoir; a plurality of hydraulic brakes provided for respective wheels of the vehicle, and configured to restrain rotations of the respective wheels; and a control valve device including at least one hydraulic-pressure control valve group disposed between the hydraulic-pressure generating device and at least one of brake cylinders of the hydraulic brakes and/or between the reservoir and the at least one of the brake cylinders. Each of the at least one hydraulic-pressure control valve group includes (a) at least one ON/OFF control valve and (b) at least one linear control valve that are disposed in parallel with each other.

摘要： A vehicle electric brake device configured such that, when no braking force request is made, a piston of an actuator of the electric brake device is retracted to a set backward position so as to allow a clearance to exist between a friction member and a rotary body of the device, wherein a controller of the device is configured to execute, for the actuator, a clearance removing control in which the piston is advanced at a first speed and subsequently advanced such that a piston advancing speed is reduced from the first speed to a second speed, so as to remove the clearance, the clearance removing control being executed when the braking force request is generated, and a braking-force-request-dependent control in which a braking force in accordance with a degree of the braking force request is generated, the braking-force-request-dependent control being executed after execution of the clearance removing control.

摘要： A vehicle brake system, wherein an electric brake device is configured such that a clearance exists between a friction member and a rotary body when no braking force request is made, and wherein a controller is configured to: execute, for a hydraulic brake device, from a time point of generation of the request, a braking-force-request-dependent control for generating a hydraulic braking force in accordance with a degree of the request; and execute, for the electric brake device, (a) a clearance removing control for removing the clearance, which is executed from the time point of generation of the request till a time point when the degree increases up to a threshold degree, and (b) a braking-force-request-dependent control for generating an electric braking force in accordance with the degree of the request, the control being executed after the time point when the degree becomes equal to the threshold degree.

摘要： An electric brake device includes: an electric brake being configured such that a shaft is moved forward by diving of an electric motor, and the forward movement of the shaft brings the electric brake into an acting state in which brake friction members are pushed against a brake rotary body so as to suppress rotation of a wheel; and a motor controller being configured to control the electric motor, wherein through a rotation speed control on the electric motor, after the shaft reaches a set position before the electric brake comes into the acting state, the motor controller controls a forward speed of the shaft to be smaller than that before the shaft reaches the set position.

摘要： A method for detecting fluid leakage from a pressure-decrease valve in a hydraulic brake system having an ABS device including: a shutoff valve for shutting off supply of a working fluid from a fluid-pressure supply source to a brake device provided for a wheel; the pressure-decrease valve for discharging the working fluid from the brake device; a reservoir for storing the working fluid discharged from the pressure-decrease valve; and a return pump for returning the working fluid stored in the reservoir to a portion between the shutoff valve and the fluid-pressure supply source, the method including the steps of: activating the return pump in a state in which the hydraulic brake system is not in ABS operation, and detecting the fluid leakage from the pressure-decrease valve based on a variation in a pressure of the working fluid in the fluid-pressure supply source caused when the return pump is activated.
