The invention discloses a cooperative control system suitable for folding prevention of a semitrailer. The cooperative control system suitable for semitrailer folding prevention comprises a folding prevention prediction module, a folding prevention decision module, a folding prevention control module and a folding prevention cooperative execution module. By judging the driving environment and the state of the vehicle, planning of a control strategy is carried out, and cooperative control of driving, differential braking and active steering is reasonably and effectively carried out; the problems that a semitrailer is out of control due to high gravity center, large mass and obvious rear amplification effect, and folding and other bad states are caused by violent shimmy easily caused by external force interference or improper operation of a driver are solved. The invention aims at solving the problem of unsteady folding of the semitrailer through cooperative control of driving, braking and steering modes, and improving the running stability of the semitrailer.
本发明公开了一种适用于半挂车防折叠的协同控制系统;该适用于半挂车防折叠的协同控制系统包括防折叠预测模块、防折叠决策模块、防折叠控制模块、防折叠协同执行模块;通过对行驶环境与车辆本身状态的判定,进行控制策略的规划,合理有效地进行驱动、差动制动、主动转向的协同控制;解决半挂车由于其重心高,质量大,后部放大作用明显而失控的问题,容易在一些外界力干扰或驾驶员不当操作下发生剧烈的摆振从而导致折叠等不良状态。本发明旨在通过对驱动、制动、转向模式的协同控制解决半挂车失稳折叠的问题,提高半挂车行驶的稳定性。
