The invention relates to a motor vehicle vacuum pump (10), comprising a pumping unit (24) having a rotatable pump rotor (26), an electronically commutated electric motor (30) for driving the pump rotor (26), a pressure sensor connector (38) for periodically receiving a pressure parameter (P) provided by a motor vehicle pressure sensor (18), and a pump control unit (34) for controlling a variable motor speed (MS) of the electric motor (30), the pump control unit (34) comprising-a standard operating control module (40) which is designed to control the variable motor speed (MS) within a standard operating speed range (SSR); a lifting drive control module (42) which, when triggered, is designed to override the standard operating control module (40) and to set a variable motor speed (MS) in accordance with lifting speed values (BS1, BS2, BSn) above the standard operating speed range (SSR); and a safety control module (44), which is designed to monitor the pressure parameter (P) and to trigger the lifting drive control module (42) on the basis of the pressure parameter (P). The pump control unit (34) according to the invention allows the motor vehicle vacuum pump (10) to be generally designed for relatively low standard operating speed ranges (SSR), but also allows temporarily improved pump performance in emergency situations. This provides a reliable and cost-effective motor vehicle vacuum pump (10).

    本发明涉及一种机动车真空泵(10),其包括具有能旋转的泵转子(26)的泵送单元(24)、用于驱动所述泵转子(26)的电子换向电动机(30)、用于周期性地接收由机动车压力传感器(18)提供的压力参数(P)的压力传感器连接器(38),和用于控制电动机(30)的可变的电动机转速(MS)的泵控制单元(34),所述泵控制单元(34)包括‑标准运行控制模块(40),所述标准运行控制模块设置用于在标准运行速度范围(SSR)内控制可变的电动机转速(MS);‑提升驱动控制模块(42),所述提升驱动控制模块设置用于在被触发时否决标准运行控制模块(40),并且与高于标准运行速度范围(SSR)的提升速度值(BS1、BS2、BSn)对应地设定可变的电动机转速(MS);‑安全控制模块(44),所述安全控制模块设置用于监控所述压力参数(P)并且基于所述压力参数(P)触发所述提升驱动控制模块(42)。按照本发明的泵控制单元(34)允许一般性地针对相对较低的标准运行速度范围(SSR)设计机动车真空泵(10),但也允许在危急情况下临时地提供提升的泵性能。这提供了一种可靠且有成本效益的机动车真空泵(10)。
