Method for controlling an actuator used to tilt a seat of a motor vehicle and motor vehicle

The method involves driving the actuator (4) for approximately in phase with the transverse or longitudinal acceleration during successful tilting of the seat (2,3) using the roll angle process or the pitch angle curve. The transverse or longitudinal acceleration is determined from data of a semi-automatic or fully automatic vehicle system (6) for transverse or longitudinal guiding of the motor vehicle (1). An independent claim is also included for a motor vehicle comprises a control device.
