Abstract
A method for controlling a pedal lever of a hydraulic power brake for an at least partially automated mobile platform. In the method, the pedal lever acts mechanically on a master brake cylinder, and the pedal lever is mechanically coupled to an actuator. The method includes: providing a first signal to a control unit for the power brake for the purpose of controlling the pedal lever so as to move same into a passive position; establishing a first hydraulic connection between the master brake cylinder and a compensating volume; and transferring a first hydraulic volume of the master brake cylinder into the compensating volume by means of the actuator acting on the pedal lever in order to control the pedal lever so as to move same into a passive position.

A method for controlling a pedal lever of a hydraulic power brake for an at least partially automated mobile platform, wherein the pedal lever acts mechanically on a master brake cylinder, and the pedal lever is mechanically coupled to an actuator, the method comprising the following steps:
- providing a first signal to a control unit for the power brake to control the pedal lever so as to move the pedal lever into a passive position;
- establishing a first hydraulic connection between the master brake cylinder and a compensating volume;
- and
- transferring a first hydraulic volume of the master brake cylinder into the compensating volume by the actuator acting on the pedal lever to control the pedal lever so as to move the pedal lever into the passive position.
A hydraulic power brake, comprising:
- an actuator;
- a plunger and/or a hydraulic reservoir;
- a control unit;
- at least a first hydraulic valve and/or second hydraulic valve;
- and
- a pressure sensor;
- wherein the control unit is configured to control a pedal lever of the hydraulic power brake for an at least partially automated mobile platform, wherein the pedal lever acts mechanically on a master brake cylinder, and the pedal lever is mechanically coupled to the actuator, the control unit configured to:
- provide a first signal to a control unit for the power brake to control the pedal lever so as to move the pedal lever into a passive position;
- establish a first hydraulic connection between the master brake cylinder and a compensating volume;
- and
- transfer a first hydraulic volume of the master brake cylinder into the compensating volume by the actuator acting on the pedal lever to control the pedal lever so as to move the pedal lever into the passive position.
