摘要： A method for operating a brake system. A brake request signal characterizing a brake request is generated by actuating a positioner system of an actuating circuit, and a setpoint brake pressure required in an active circuit is ascertained based on the brake request signal. An actual brake pressure is set in the active circuit according to the setpoint brake pressure using a pressure generation device by moving a displacement piston using an electric motor to actuate a wheel brake coupled with the active circuit. Under the condition that the brake request signal is constant over a predefined period of time, a pressure modulation is carried out, which includes setting the actual brake pressure in the active circuit to a value that is greater than the setpoint brake pressure, and lowering the actual brake pressure by moving the displacement piston using the electric motor until the setpoint brake pressure is reached.

摘要： A method for determining a start time for a recharging procedure for a plunger device of an electronically slip-controllable power brake system, and an electronically slip-controllable power brake system having a plunger device. Plunger devices have a plunger cylinder, a plunger piston, and a plunger working space and are operable by a drive motor. A recharging procedure of the plunger device is required from time to time. The start time for a recharging procedure of the plunger device is ascertained as a function of characteristic values that describe the driving state of a vehicle equipped with the power brake system, and/or the operating state of the plunger device when an actual position of the plunger piston lies within a specifiable working range of the plunger device.

摘要： The present invention relates to a method for avoiding excess pressures in a pressure medium circuit of an electronically slip-controllable braking system in the event of a decline of an intrinsic elasticity of the braking system and an electronically slip-controllable braking system. Electronic control units, ascertain a setpoint value for a delivery volume of the pressure generator of these braking systems and convert it into an activation signal for the drive of the pressure generator. In dependence on the prevailing elasticity of the pressure medium circuit, a pressure gradient is established, using which the pressure in the pressure medium circuit changes over time. The ascertainment of an activation signal for the drive of the pressure generator by the electronic control unit is based on the established pressure gradient.

摘要： A power brake system having electronic slip regulation, and a method for controlling a power brake system having electronic slip regulation. A return line is equipped with a pressure medium storage unit for storing pressure medium with a pressure that is greater than an ambient atmospheric pressure, and is equipped with a blocking device that is controllable and that is situated between the pressure medium storage device and the reservoir. In addition, there is a pressure medium connection between the pressure medium storage unit and the plunger working space. A controlling of a power brake system takes place using the blocking device in such a way that the return line is blocked relative to the reservoir as soon as a plunger piston, driven by a drive unit, has traveled a definable path in the forward direction.

摘要： A method is described for detecting a leakage during the operation of a braking system. A braking intention signal characterizing a braking intention is generated by actuating a final control system of an actuating circuit; a setpoint braking pressure required in an active circuit is ascertained based on the braking intention signal; an actual braking pressure in the active circuit is set according to the setpoint braking pressure with the aid of a pressure generation unit by moving a displacement piston to actuate a wheel brake coupled to the active circuit; and a pressure modulation is carried out. The pressure modulation includes setting the actual braking pressure in the active circuit to a value greater than the setpoint braking pressure, and lowering the actual braking pressure until the setpoint braking pressure is reached by moving the displacement piston at a predetermined piston speed. Furthermore, a chronological pressure gradient is ascertained, as the actual braking pressure is being lowered, during the pressure modulation, and a leakage of the active circuit is detected based on the ascertained pressure gradient when the pressure gradient is outside a range predetermined for the piston speed.
