摘要： A brake system includes first and second wheel brakes, a reservoir, and a brake pedal unit having a housing and a pair of output pistons slidably disposed in the housing. The output pistons generate brake actuating pressure during a manual push-through mode for actuating the first and second wheel brakes. The system further includes a plunger assembly having a housing having a motor driving an actuator, and a piston connected to the actuator. The piston pressurizes a chamber when the piston is moving in a first direction to provide fluid flow out of a first port and through a pair of parallel valves. The piston pressurizes a second chamber when the piston is moving in a second direction opposite the first direction to provide fluid flow out of a second port. The first and second ports are selectively in fluid communication with the wheel brakes.

摘要： A braking control device comprising: an operation amount acquisition device that obtains an operation amount for a braking operation member; a pressurizing unit that presses a friction member to a rotating member fixed to a wheel using an electric motor; a control that controls output of the electric motor based on the operation amount; a pressing force acquisition device that obtains the actual pressing force of the friction member pressing on the rotating member; and a rotation angle acquisition device that obtains the actual rotation angle of the motor. The control: stores the correlation between the actual pressing force and the actual rotation angle; approximates a function map indicated by a second degree or higher polynominal, based on the correlation; calculates a target rotation angle based on the operation amount and the function map; and controls the electric motor to match actual rotation angle and the target rotation angle.

摘要： A method for controlling a hydraulic brake system during a regenerative braking process where a displacement of a hydraulic fluid in the direction of a wheel brake is performed by means of a brake cylinder and at least one volume fraction of the hydraulic fluid is conducted via a pressure dissipation valve, which is situated in an open position, into an accumulator. In the method, furthermore, the pressure dissipation valve is adjusted in the direction of a closed state, in order to realize an increase of a hydraulic braking torque effected by the wheel brake, if an overall braking torque which is made up of the hydraulic braking torque and a generator braking torque effected by an electric machine is lower than a braking torque demand, and if the generator braking torque lies below a braking torque limit of the electric machine.

摘要： The method relates to a method for boosting the braking force in an electromotor operated slip-controllable vehicle brake system having electromechanical brake boosting. The vehicle brake system includes a braking-intention detection device, an electromechanically actuatable brake booster, and an electronically actuatable brake-pressure control device. In the event of a malfunction of the brake booster, the boosting of the brake pressure is alternatively assumed by the brake-pressure control device. In the event of a malfunction of the brake boosting, it is checked whether a generation and a transmission of a trigger signal representing the actuation of the braking-intention detection device from the first electronic control device of the brake booster to a second electronic control device of the brake-pressure control device is possible, and if this is so, the trigger signal is transmitted via an existing communications link between the control devices.

摘要： A master cylinder and an electronic brake system including the same are disclosed. The electronic brake system includes a main hydraulic-pressure supply device to generate hydraulic pressure by sensing displacement of a brake pedal and a sub hydraulic-pressure supply unit to supply hydraulic pressure to at least one wheel cylinder during an abnormal operation of the main hydraulic-pressure supply device. The master cylinder includes a first piston disposed in a bore of a cylinder body so as to be directly pressurized by the brake pedal, a first hydraulic chamber pressurized by the first piston to discharge hydraulic pressure, a second piston indirectly pressurized by the first piston, and a second hydraulic chamber pressurized by the second piston to discharge hydraulic pressure. The second hydraulic chamber includes a slippage prevention means connected to the sub hydraulic-pressure supply unit so as to prevent the second piston from moving toward the first piston by the hydraulic pressure received from the sub hydraulic-pressure supply unit.
