The invention discloses a vehicle speed control method for stable turning of a vehicle. The method is characterized by mainly comprising a stable turning speed calculation system, a pre-turning control distance calculation module, a distance identification module, a pre-turning distance judgment module, a model prediction control module, a reverse dynamic model and a controlled vehicle. The stable turning-in vehicle speed calculation system is used for determining a stable turning-in vehicle speed; the pre-turning control distance calculation module is used for calculating the distance from a vehicle braking starting point to a turning point; the distance identification module is used for identifying the distance between the current position of the vehicle and the bending point; the pre-turning distance judgment module is used for determining whether to input the stable turning vehicle speed into the model prediction control module or not; the model prediction control model is used for optimizing longitudinal braking deceleration; the reverse dynamic model is used for outputting brake pressure; and the controlled vehicle outputs the longitudinal speed and the longitudinal acceleration. According to the method, the stability and comfort of the vehicle in the bending process can be improved, and the probability of sideslip and rollover accidents is reduced.

    一种车辆稳定入弯的车速控制方法,其特征在于该方法主要包括稳定入弯车速计算系统、预转弯控制距离计算模块、距离识别模块、预转弯距离判断模块、模型预测控制模块、逆向动力学模型和被控车辆。稳定入弯车速计算系统用于确定稳定入弯车速;预转弯控制距离计算模块用于计算车辆开始制动点至入弯点距离;距离识别模块用于识别车辆当前位置与入弯点间距离;预转弯距离判断模块用于决定是否将稳定入弯车速输入到模型预测控制模块中;模型预测控制模型用于优化纵向制动减速度;逆向动力学模型用于输出制动压力;被控车辆输出纵向速度、纵向加速度。该方法能够提升车辆入弯过程中的稳定性与舒适性,降低侧滑和侧翻事故发生的概率。
