The disclosure relates to a method for operating a hydraulic braking system in a motor vehicle having a regenerative braking function. The method comprises steps that, with respect to at least two wheel brakes, a hydraulic free travel release is carried out such that, with respect to one of the at least two wheel brakes, a hydraulic passage to an accumulator is released in order to store therein at least a volume fraction of the hydraulic fluid in the event of a displacement of a hydraulic fluid. The other of the at least two wheel brakes is hydraulically isolated. The disclosure also relates to a hydraulic braking system for a motor vehicle having a regenerative braking function and a method for controlling said braking system.

Hydraulic braking system, including a control system, and method for controlling said braking system

The disclosed electromechanical brake booster for a vehicle brake system comprises a driving arrangement for driving at least one actuation device designed to actuate a brake cylinder. The driving arrangement includes at least one electric motor and a gear mechanism for coupling the electric motor to the at least one actuation device. The gear mechanism comprises at least one first spur gear and at least one second spur gear, the electric motor driving the first spur gear directly and the second gear via at least one intermediate gear.

Electromechanical brake booster

The invention relates to an assembly for a vehicle brake system, which comprises at least one brake cylinder and an electromechanical brake booster, having a drive arrangement for driving at least one actuating device designed for actuating a brake cylinder, wherein the drive arrangement has at least one electric motor and a gear mechanism for coupling the electric motor to the at least one actuating device, wherein at least one fastening device is provided for fastening the assembly to a vehicle, said fastening device defining a fastening plane. According to the invention the rotary shaft of the electric motor is arranged perpendicular to the longitudinal axis of the actuating device and at an angle of between 60&#xb0; and 120&#xb0; to the fastening plane.

Assembly having a brake cylinder and an electromechanical brake booster

The electromechanical brake force booster for a vehicle brake system comprises a drive arrangement for driving at least one actuating device which is designed for actuating a brake cylinder. The drive arrangement has at least one electric motor and a gearing for coupling the electric motor to the at least one actuating device. The gearing comprises at least one second spur gear and at least one first spur gear. Furthermore, the gearing has an intermediate gearing stage. The intermediate gearing stage couples the electric motor to the second spur gear and to the first spur gear in torque-transmitting fashion. The intermediate gearing stage drives the second spur gear directly and the first spur gear via at least one intermediate gear.

Electromechanical brake force booster

A hydraulic assembly for a vehicle brake system comprising at least two brake circuits and wheel brakes associated with the brake circuits. The hydraulic assembly comprises a pressure generator for generating a central hydraulic pressure for the brake circuits independently of the driver at least in the case of service braking initiated by the driver. Furthermore, at least one pressure adjusting device is provided for adjusting for each individual brake circuit the central hydraulic pressure that is generated by the pressure generator independently of the driver.
