Because of the inexpert driving skill of novice drivers, there is often collision in the parking process. Fortunately, with the development of path planning and intelligent control technology, the appearance of the automatic parking control system will provide a good solution to the narrow parking problems. Here with the help of MATLAB/Simulink, we build a simulation platform, and then respectively simulate the parallel parking and vertical parking process, to seek for the best initial parking point and path.展开更多
