Parking system using open/closed loop control activated by accelerator operation

摘要

A semi-automatic parking control system of a motor vehicle 1 comprises process steps including using a parking space gauging system 4 and sensors 11 to gauge a parking space. A control system 6 calculates a trajectory (3, fig 4) and an automatic parking manoeuvre for traversing the trajectory is activated by operation of an accelerator pedal. An open and/or a closed loop control device 7 controls, during activation of the accelerator pedal and providing the vehicle 1 does not exceed a certain speed, the vehicle 1 into the parking space. If the accelerator pedal is released the open/closed loop control device 7 initiates a defined reduction of a speed of the vehicle 1 until the vehicle 1 comes to a standstill. The speed reduction is determined as a function of current speed and as a function of a position (5, 8) of the motor vehicle 1 along the trajectory (3). The parking system also comprises an electric wheel drive 17 and an electric steering drive 18 which sets a steering angle β of the driven wheels 2.
