The invention discloses a slip steering control system for a vehicle. The slip steering control system comprises a signal acquisition unit and a controller which are connected with each other, whereinthe controller comprises a linear deviation rectification control layer, a pivot steering control layer and a steering control layer which are respectively connected with the signal acquisition unit;the controller judges the working condition of the vehicle based on related data in the signal acquisition unit, then calls the linear deviation rectification control layer, the pivot steering control layer or the steering control layer corresponding to the working condition based on the working condition of the vehicle, adjusts the torque value of a motor connected with each wheel in the vehiclein real time, and completes the slip steering control of the vehicle. According to the invention, the judgment of pivot steering, straight line and steering driving working conditions is achieved, different control strategies are adopted based on different working conditions, and the stability of vehicle steering is kept.
本发明公开了一种用于车辆的滑移转向控制系统,包括相连的信号采集单元和控制器,所述控制器包括分别与所述信号采集单元相连的直线纠偏控制层、原地转向控制层和转向控制层;所述控制器基于所述信号采集单元中的相关数据,判断出车辆所处的工况,然后基于车辆所处的工况,调用与该工况对应的直线纠偏控制层、原地转向控制层或转向控制层,实时调节车辆中与各车轮相连的电机的力矩值,完成车辆的滑移转向控制。本发明实现了原地转向、直线和转向行驶工况的判断,并基于不同的工况采用不同的控制策略,保持车辆转向的稳定性。
