Abstract

The embodiment of the invention provides an automatic parking control method and device and a controller. The method comprises the steps: receiving an automatic parking request signal of a user; responding to the automatic parking request signal, and obtaining vehicle parameters of a vehicle and a reference track of the vehicle driving to a parking position from the current position; obtaining a preview distance through a preset preview distance model according to the current vehicle speed; determining a first parameter for transversely controlling the vehicle according to the preview distance, the target position, the vehicle steering transmission ratio and the vehicle axle distance, the first parameter comprising a steering wheel angle of the vehicle; and adjusting a steering wheel of the vehicle according to the steering wheel rotation angle of the vehicle so as to control the vehicle to perform automatic parking. According to the embodiment of the application, the automatic parkingcontrol of the vehicle can be realized.

Description

technical field [0001] The embodiments of the present application relate to the field of cruising technology, and in particular to an automatic parking control method, device and controller. Background technique [0002] Driving safety has always been a hot issue in the automotive industry. With the continuous advancement of intelligent driving technology, more and more automatic safety technologies have been applied to automobiles, such as automatic control systems. The wide application of these new technologies not only improves the driving performance of automobiles Safe, and it improves the driving feel of the car. [0003] At present, most of the technical solutions for vehicle lateral control in automatic control systems are based on vehicle kinematics and dynamics models to design control algorithms to make the vehicle drive along a known trajectory (path). However, the current automatic control methods are all used for the control when the vehicle is moving forward,...
