  • Method for Autonomous Parking of a Motor Vehicle, Driver Assistance Device for Performing the Method and Motor Vehicle with the Driver Assistance Device
    Publication number: 20150088360
    Abstract: An autonomous parking procedure of a motor vehicle involves transferring a command to activate the autonomous parking procedure using a communication link between an operator situated outside the motor vehicle and the motor vehicle. Before beginning the autonomous parking procedure of the motor vehicle the target position and/or last driven trajectory of the motor vehicle is stored in a storage device. The motor vehicle then performs the parking procedure autonomously from the start position using the stored data after the first activation of the autonomous parking procedure.
