Abstract:
A method for controlling an automotive hydraulic pump, wherein the hydraulic pump is activated to increase the pressure in a hydraulic accumulator associated therewith once the pressure falls below a predetermined lower pressure threshold, and the hydraulic pump is switched off once the pressure exceeds a predetermined upper pressure threshold value (P_O). The solution is to reduce fuel consumption of the vehicle, wherein the hydraulic pump is activated during different operating phases of the vehicle at different lower pressure values (P_U1, P_U2) in the event of a hydraulic pressure drop in the hydraulic accumulator of the hydraulic pump.
