The invention relates to the technical field of vehicle steering control, in particular to a vehicle active rear wheel steering control method and system based on driving working conditions. The method comprises the steps of firstly obtaining a current driving state of a target vehicle; according to the current driving state, the driving industrial control of the target vehicle is judged; and according to the driving working condition, a corresponding control strategy is switched to control rear wheels of the target vehicle. Different from a traditional rear wheel follow-up steering technology, different control methods can be adopted to control rear wheel steering according to different driving working conditions of the target vehicle so as to achieve optimal control, the control stability and flexibility of the target vehicle are improved, and the control efficiency is improved. The problems that existing rear wheel follow-up steering is not high in adaptability to different driving working conditions, and operation stability is common are solved.
本发明涉及车辆转向控制技术领域,更具体的,涉及基于行驶工况的车辆主动后轮转向控制方法、系统。本发明先获取目标车辆的当前行驶状态;依据当前行驶状态,判断目标车辆所处的行驶工控;再根据行驶工况,切换对应的控制策略对目标车辆的后轮进行控制。与传统的后轮随动转向技术不同,本发明能够根据目标车辆不同的行驶工况,采用不同的控制方法控制后轮转向以实现最优控制,并提高目标车辆的操纵稳定性、灵活性,解决了现有后轮随动转向对于不同的行驶工况适配度不高、操作稳定性一般的问题。
