The invention relates to a vacuum pump control method (1) for controlling an electric vacuum pump (128), comprising the steps of: determining (S3) an available vacuum level (Va) of a vacuum brake booster (104a, 104b) of a brake system (100); comparing (S4) the available vacuum level (Va) with the access vacuum level (V2); determining (S6) a brake request strength (119) of a brake request (108) provided to the brake system (100); determining (S8) a required vacuum level (Vr) based on the braking request intensity (119); comparing (S11) the available vacuum level (Va) with the required vacuum level (Vr); and operating (S12) the electric vacuum pump (128) to provide vacuum to the vacuum brake booster (104a, 104b) when the available vacuum level (Va) is below the required vacuum level (Vr) and below the access vacuum level (V2). The invention also relates to a brake system (100) and a vehicle (200).

    本发明涉及一种真空泵控制方法(1)以用于控制电真空泵(128),包括以下步骤:确定(S3)制动系统(100)的真空制动助力器(104a,104b)的可用真空水平(Va);将该可用真空水平(Va)与接入真空水平(V2)进行比较(S4);确定(S6)提供给该制动系统(100)的制动请求(108)的制动请求强度(119);基于制动请求强度(119)确定(S8)要求真空水平(Vr);将可用真空水平(Va)与要求真空水平(Vr)进行比较(S11);以及当可用真空水平(Va)低于要求真空水平(Vr)并且低于接入真空水平(V2)时,操作(S12)电真空泵(128)以向真空制动助力器(104a,104b)提供真空。本发明还涉及一种制动系统(100)和一种车辆(200)。
