Original Abstract Submitted

A motor vehicle has an electric drive machine for driving the motor vehicle and a coupling mechanism which can be switched at least between a coupling position, in which the electric drive machine is coupled to a drive wheel so as to transmit torque, and a decoupling position in which the electric drive machine is decoupled from the drive wheel. A parking lock device has at least one parking lock element that can be moved between a parking lock position, in which the at least one parking lock element at least indirectly blocks a rotation of the drive wheel, and an unlocking position in which the at least one parking lock element releases the rotation of the drive wheel. An actuation device with an actuator is designed to actuate a clutch of the coupling mechanism, which clutch has at least one switching element and is used to switch between the coupling position and the decoupling position, and is designed to move the at least one parking lock element between the parking lock position and the unlocking position. The switching element has a retaining region preventing the parking lock element from moving into the parking lock position as long as the lock has not been adjusted to the coupling position.
