The invention relates to the field of vehicle active safety control, in particular to a coordination control method for vehicle transverse stability. The method comprises the following steps that S1,judging the transverse stability state of a vehicle according to the characteristic attribute, obtained in real time, of the transverse stability of the vehicle, wherein the transverse stability stateof the vehicle comprises three categories; S2, calculating the distance between the data point of the current vehicle state and the category center point of the three types of vehicle transverse stability states, determining values of adaptive adjustment coefficients lambda of a driving front wheel steering controller and a direct yawing moment controller in the coordination controller accordingto the distance; S3, determining a control strategy of the coordination controller in combination with the transverse stability state of the current vehicle; and S4, executing the control strategy andmonitoring the regulated transverse stability state of the vehicle, and continuously executing a new regulation strategy for the monitoring result. The coordination controller in the method is mainlyused for precisely regulating and controlling the vehicle according to the current transverse stability state of the vehicle, and the control precision and effect are better.
本发明涉及车辆主动安全控制领域,特别是一种车辆横向稳定性的协调控制方法。该方法包括如下步骤:S1:根据实时获取的车辆横向稳定性的特征属性判定车辆的横向稳定状态;车辆横向稳定状态包括三个类别;S2:计算当前车辆状态的数据点与三类车辆横向稳定性状态的类别中心点的距离;根据距离确定协调控制器中主动前轮转向控制器和直接横摆力矩控制器的自适应调节系数λ的值;S3:结合当前车辆的横向稳定状态确定协调控制器的控制策略;S4:执行控制策略并监测车辆调控后的横向稳定状态,针对监测结果持续执行新的调控策略。该方法中的协调控制器主要根据车辆当前的横向稳定性状态对车辆进行精准调控,控制精度和效果更好。
