The invention relates to a vehicle having an electric motor (EM) which drives a wheel (2) via a transmission mechanism, in which a parking lock (4) having a pawl (5) and a locking gear (7) is mounted, in a specific parking state, the engaged pawl (5) is clamped, and in which the engaged pawl (5) is unclamped for unstressed parking lock release. A central control unit (11) actuates a pulse inverter (PWR) of an electric machine (EM) in order to rotate a rotor shaft (1) of the electric machine by a target rotation angle (alphasoll) in a direction of rotation (D), in particular to generate a reduced-pressure torque (M), by means of which clamping acting on the parking lock (4) can be reduced. According to the invention, the pulse inverter (PWR) is connected together with the rotor position sensor (15) into the adjustment circuit (R). By means of the adjustment circuit (R), a rotational angle adjustment mode can be carried out, in which the electric machine (EM) is actuated by means of the reduced-pressure torque (M).
