The invention provides a brake energy recovery control method and system which are applied to a decoupling type electronic power-assisted brake system, and the method comprises the following steps: when a preset condition is met, recovering the brake energy of the decoupling type electronic power-assisted brake system; determining a steady-state factor according to the driving state of the vehicle; and when braking energy recovery is carried out according to the braking signal, adjusting the torque value of braking energy recovery in real time according to the steady-state factor. By means of the mode, the problems of whole vehicle dynamic control deviation and whole vehicle shaking caused by braking energy recovery of the vehicle under special working conditions can be effectively solved, and the driving experience of a user is improved.
本发明提供了一种制动能量回收控制方法及系统,应用于解耦式电子助力刹车系统,方法包括:满足预设条件时,对解耦式电子助力刹车系统的制动能量进行回收;根据车辆的驾驶状态确定稳态因子;根据制动信号进行制动能量回收时,根据稳态因子实时调整制动能量回收的扭矩值。通过上述方式,能有效避免车辆在特殊工况下制动能量回收导致的整车动态控制偏差及整车抖动的问题,提高用户的驾驶体验。
