The invention provides a curve driving control method for a hybrid vehicle, which comprises the following steps that: an upper-layer controller adopts adaptive cruise based on model predictive control to obtain expected acceleration and force of four tires so as to realize longitudinal vehicle following control of the hybrid vehicle; the lower-layer controller adopts active model predictive control of the suspension and outputs active force of the suspension, so that lateral stable control of the hybrid power vehicle is realized; through the upper-layer controller and the lower-layer controller, the smoothness and the control stability of curve driving of the hybrid electric vehicle are guaranteed; according to the energy feedback suspension module, electromagnetic force is utilized, the battery power is determined, when the battery power is smaller than 0, the driving motor serves as a generator, part of suspension mechanical energy is converted into electric energy to be stored in the battery, energy regeneration is achieved, and the fuel economy of curve running of the hybrid electric vehicle is guaranteed.

    本发明提供了一种混合动力车辆弯道行驶控制方法,上层控制器采用基于模型预测控制的自适性巡航,获取期望加速度和四个轮胎力,实现混合动力车辆纵向跟车控制;下层控制器采用悬架主动的模型预测控制,输出悬架主动力,实现混合动力车辆侧向稳定控制;本发明通过上下层控制器,保证混合动力车弯道行驶的平顺性、操纵稳定性;本发明的馈能悬架模块利用电磁力,确定电池功率,当电池功率小于0时,驱动电机充当发电机作用,部分悬架机械能转化为电能,储存在电池中,实现能量再生,保证混合动力车弯道行驶的燃油经济性。
