The invention belongs to the technical field of hybrid electric vehicles, and particularly relates to a control method for braking energy recovery of a hybrid electric vehicle. According to the method, various factors such as the position of the brake pedal, the opening degree of the accelerator pedal, the vehicle speed, the gear, the ABS state, the ESP state, the TCS state, the ESC fault state and the brake pedal fault state are considered more comprehensively, and the effect of improving the safety and economical efficiency of the vehicle is better. In the braking energy recovery mode, the quit conditions are judged and divided into the safety quit condition and the non-safety quit condition, refined control over braking energy recovery quit is achieved, consideration is more accurate, and on the premise that the safety of the vehicle is guaranteed, the driving comfort is greatly improved.
本发明属于混合动力汽车技术领域,具体的说是一种混合动力汽车制动能量回收的控制方法。本发明以制动踏板位置、油门踏板开度、车速、挡位、ABS状态、ESP状态、TCS状态、ESC故障状态、制动踏板故障状态等多种因素,考虑得更为全面,对于车辆安全性和经济性的提升作用更大。在处于制动能量回收模式下,对退出条件进行判断,将退出条件分为安全性退出条件和非安全性退出条件,实现制动能量回收退出的精细化控制,考虑得更为精准,在保证车辆安全性的前提下,对驾驶舒适性提升更大。
