A control device may assist in parking maneuvers of a vehicle. The control device may include an interface to a sensor unit for detecting a boundary of a parking space in the surroundings of the vehicle. An arithmetic unit may determine a trajectory into a parking position in the parking space. In some embodiments the arithmetic unit is configured to calculate a trajectory into the parking position, taking into account a potential extension of parts of the body of the vehicle beyond the boundary of the parking space. Devices and methods are provided.
