The invention provides a vehicle stability control method, electronic equipment, a storage medium and a program product, and the method comprises the steps: calculating the nominal state of a vehicle, and obtaining the ideal yaw velocity of the vehicle; comparing the actual yaw velocity with the ideal yaw velocity to obtain different first steering working conditions; and based on the first steering working condition and the vehicle stability phase diagram constraint, the vehicle stability state is divided into a plurality of second steering working conditions, and corresponding vehicle body stability control strategies are adopted under the different second steering working conditions. According to the method, the second steering working condition for working of the steer-by-wire system and the vehicle body electronic stability system is clearly divided, and the appropriate vehicle body stability control strategy is executed according to the vehicle dynamic characteristics under the second steering working condition. Only when the steer-by-wire system cannot meet the stability control requirement, the vehicle enters the cooperative control state of the steer-by-wire system and the vehicle body electronic stabilization system or the independent control state of the vehicle body electronic stabilization system, and the stability and safety of vehicle running are effectively improved.
本申请提供一种车辆稳定性控制方法、电子设备、存储介质及程序产品,方法包括:计算车辆的名义状态,得到车辆的理想横摆角速度;将实际横摆角速度与理想横摆角速度的对比,得到不同的第一转向工况;基于第一转向工况和车辆稳定性相图约束,将车辆稳定状态划分为多个第二转向工况,并于不同的第二转向工况下采用相应的车身稳定控制策略。本申请明确划分线控转向系统与车身电子稳定系统进行工作的第二转向工况,并根据第二转向工况下的车辆动态特性执行合适的车身稳定控制策略。只有当线控转向系统不能满足稳定性控制需求后才进入线控转向系统与车身电子稳定系统的协同控制或车身电子稳定系统单独控制状态,有效提高了车辆行驶的稳定性和安全性。
