Method for controlling parked vehicle to be driven out parallelly

Abstract

The invention discloses a method for controlling a parked vehicle to be driven out parallelly. A vehicle parking control system enables a steering wheel to rotate in the direction opposite to the driving-out direction to a limiting position, and the driven vehicle begins to run backwards; when the distance between the driven vehicle and a vehicle behind the driven vehicle is shorter than a set safety vehicle distance, the driven vehicle stops running, the vehicle parking control system enables the steering wheel to rotate in the direction which is the same as the driving-out direction to a limiting position, and the berthed vehicle begins to run forwards; when the distance between the driven vehicle and a vehicle in front of the driven vehicle is smaller than the set safety vehicle distance, the driven vehicle stops running; the above steps are conducted again till the front vehicle distance is longer than the set vehicle distance allowing the vehicle to be driven out, the vehicle parking control system enables the steering wheel to rotate in the direction opposite to the driven-out direction to a limiting position till the front vehicle distance and the rear vehicle distance are both longer than the set vehicle distance allowing the vehicle to be driven out. The method can effectively improve the safety, and select the optimal vehicle running path according to the practical size of a parking lot, thereby adapting to a parallel parking lot with the short length.

Description

technical field [0001] The invention relates to the technical field of automatic control of automobiles, in particular to a method for controlling parallel parking of vehicles. Background technique [0002] In car driving technology, parking a car in and out of a parking space is a relatively difficult technology. Improper control causes scratches with vehicles next to it, or it takes a long time to back and forth because of fear of scratches, especially for some smaller parallel parking spaces, it is simply impossible to achieve safe parking and parking. For this reason, people have invented some automatic parking systems, which can realize the automatic parking of vehicles, thereby facilitating the driver's operation and avoiding scratching accidents caused by parking. For example, "a car and an automatic parking system and automatic parking method applied to the car" disclosed in the Chinese patent literature, its announcement number is CN102975715B, the car includes ste...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problems of low security existing in the existing automatic parking method, difficulty in adapting to parallel parking spaces with a short length, and inability to realize the optimal driving path, and to provide a parallel parking method for controlling parking out of vehicles. The proposed method can effectively improve safety, and select the optimal driving path according to the actual size of the parking space, so that it can adapt to parallel parking spaces with a short length
