The invention is directed to a motor vehicle vacuum pump (10), comprising - a pumping unit (24) with a rotatable pump rotor (26), - an electronically commutated electric motor (30) for driving the pump rotor (26), and - a pump control unit (34) for controlling a variable rotational motor speed (MS) of the electric motor (30), wherein the pump control unit (34) comprises - a deceleration map storage (40) storing a deceleration map (42) with at least one time-dependent and/or motor-speed-dependent motor deceleration parameter (DP1,DP2), and - a rotor-stopping control module (44) which is connected with the deceleration map storage (40) and which is configured to actively control the variable rotational motor speed (MS) based on the deceleration map (42) during a rotor stopping process (RSP). The pump control unit (34) according to the present invention provides an actively controlled rotor stopping process (RSP) which reliably avoids an abrupt venting of the motor vehicle vacuum pump (10) and thus minimizes humidity and contamination intrusion into the vacuum pump and minimizes noise. This provides a reliable and low-noise motor vehicle vacuum pump (10).
