The present invention is applicable to the field of semi-automatic parking, and provides a semi-automatic parking system path planning method. The method comprises the following steps: parameter information of a vehicle is input into a semi-automatic parking system; the semi-automatic parking system calculates and generates a reference trajectory of the vehicle according to the parameter information of the vehicle in the step S1, and the reference trajectory is stored in the system; the parking parameter information of the vehicle is input into the semi-automatic parking system; and accordingto the parking parameter information input in step S3, the reference trajectory obtained in step S2 is invoked to be spliced with a linear trajectory, and the semi-automatic parking system calculatesand generates the parking trajectory of the vehicle. The obtained semi-automatic parking trajectory is more accurate, and the trajectory is continuous and realizable, thereby better facilitating accurate parking.
Description
technical field [0001] The invention belongs to the field of semi-automatic parking, in particular to a path planning method for a semi-automatic parking system. Background technique [0002] At present, the popularity of cars is increasing day by day, many families have cars, and the demand for the development of intelligent cars is becoming more and more urgent. Semi-automatic parking technology has emerged as the times require. It can not only help car owners to park quickly, but also For novice drivers, it provides a lot of help. To make the vehicle park successfully, the system first needs to have the correct vehicle parking trajectory method, but the existing path planning method applied to the semi-automatic parking system, the trajectory design is relatively simple, often directly connected by arc segments, resulting in The trajectory cannot be realized accurately, and it is not the most suitable trajectory, which may easily lead to parking failure or even a collisi...
