Claim of US Patent No. 9,327,705

1. A method for controlling a vehicle, equipped with a drive unit and a brake device, during a parking operation next to an
object, comprising:
detecting a distance to the object;
detecting an angle of inclination of the vehicle;
detecting a movement direction of the vehicle relative to the angle of inclination;
determining a first distance of the vehicle from the object as a function of the detected angle of inclination and the detected
movement direction;

accelerating the vehicle from a stand still by the drive unit bringing a speed of the vehicle to a parking speed up to the
first distance of the vehicle from the object, the parking speed maximally corresponding to a drive speed achievable with
an idle speed of the drive unit;

maintaining the speed automatically by the drive unit; and
after reaching the first distance and before attaining a second distance to the object, corresponding to a stopping distance,
decelerating the vehicle to a standstill by the brake device;

wherein the vehicle is moved up to the first distance to the object using the idle speed of the drive unit and an approximately
closed clutch for force transmission, and after the first distance has been reached, the clutch is opened until the second
distance has been reached.
