Abstract
The disclosure relates to a method for releasing an electro-hydraulic parking brake of a motor vehicle, wherein a vehicle status is determined, in dependence on the vehicle status, a pre-charging pressure demand is determined by a control device, in the event of a pre-charging pressure demand, a hydraulic pre-charging pressure is generated by a pressure generating unit, and in the event of a parking brake release demand, the pre-charging pressure is directed to the electro-hydraulic parking brake.
Claims15
A method for releasing an electro-hydraulic parking brake of a motor vehicle, wherein:
- a vehicle status is determined;
- in dependence on the vehicle status, a pre-charging pressure demand is determined by a control device;
- in the event of a pre-charging pressure demand, a hydraulic pre-charging pressure is generated by a pressure generating unit and a hydraulic volume is confined within the pressure generating unit by a plurality of valves;
- in the event of a parking brake release demand, the pre-charging pressure is released from confinement within the pressure generating unit and directed to a hydraulic chamber of the electro-hydraulic parking brake.
