The invention discloses a braking energy recovery method. The method comprises the steps that the driving mode and the driving working condition of a current vehicle are recognized; determining a total braking demand according to the driving mode and the driving working condition; distributing the total braking demand to obtain an electric braking torque and a hydraulic braking torque; and the vehicle is controlled through the electric braking torque and the hydraulic braking torque, so that braking energy recovery is achieved. By identifying the driving mode, whether the driving mode is a human driving mode or an intelligent driving mode can be identified, and then the total braking requirement is determined according to the driving working condition in the human driving mode or the intelligent driving mode, so that coordinated distribution is performed on electro-hydraulic braking; the problem of smoothness caused by coordination of feedback arbitration and electro-hydraulic braking under sliding, manual driving and intelligent driving under an existing framework can be solved.

    本发明公开了一种制动能量回收方法,所述方法包括:识别当前车辆的驾驶模式和驾驶工况;根据所述驾驶模式和驾驶工况确定总制动需求;对所述总制动需求进行分配,得到电制动扭矩和液压制动扭矩;以所述电制动扭矩和所述液压制动扭矩对车辆进行控制,以实现制动能量回收。本发明通过对驾驶模式的识别,可以实别出是人驾模式还是智驾模式,然后根据人驾模式或智驾模式下的驾驶工况来确定总制动需求,从而对电液制动进行协调分配,可以解决现有架构下滑行、人驾、智驾下的回馈仲裁和电液制动的协调带来的平顺性问题。
