Abstract: In one aspect, the present disclosure relates to a method for performing a parking operation of a motor vehicle into a transverse parking space by means of a parking assistance system of the motor vehicle. With the method of the present disclosure, environmental information related to an environment of the motor vehicle can be captured by one or more sensors. The transverse parking space further can be detected by a controller of the parking assistance system depending on the environmental information, and one or more control signals can be received at a steering system of the motor vehicle. Based upon the one or more control signals received at the steering system, the motor vehicle can be guided from a current position through an entry side of the transverse parking space into the transverse parking space.
