The invention provides a vehicle chassis system control method, which belongs to the technical field of vehicle control, and comprises the following steps: upper-layer control: respectively taking the safety, comfort and stability of the whole vehicle as three optimization targets, setting the weight of each optimization target according to environment information sensed by a vehicle-mounted sensor, realizing game balance solution, and setting the weight of each optimization target; obtaining a control target of each subsystem; middle-layer control: taking the control target of each subsystem, the environment information and the parameter information of the vehicle model as the input of machine learning, and obtaining the value of the control variable of each subsystem after the machine learning; in the lower-layer control, the values of the control variables of all the subsystems are transmitted into model prediction, the model prediction makes a control decision according to the values of all the control variables and the current state of the vehicle, control over a chassis system is achieved, and the control execution condition is fed back to the middle-layer control. According to the invention, conflicts among the systems can be effectively avoided, and the comfort, safety and stability of the vehicle can be ensured.
本发明提供一种车辆底盘系统控制方法,属于车辆控制技术领域,包括:上层控制:分别以车辆整体的安全性、舒适性和稳定性作为三个优化目标,根据车载传感器感知的环境信息,设定各优化目标的权重,实现博弈平衡求解,得到各子系统的控制目标;中层控制:将各子系统的控制目标、环境信息和车辆模型的参数信息作为机器学习的输入,经过机器学习后得到各子系统的控制变量的值;下层控制:将各子系统的控制变量的值传入模型预测,模型预测根据各控制变量的值和当前车辆的状态,制定控制决策,实现对底盘系统的控制,并将控制执行情况反馈至中层控制。本发明能够有效避免各系统之间的冲突,并且能够保证车辆的舒适性、安全性和稳定性。
