The coordinated control method for the regenerative braking and anti-lock braking device of the hybrid electric vehicle comprises the following steps: identifying the type of a current road surface, and solving a slip rate threshold value of the current road surface according to a u-s curve; if the current slip rate exceeds a threshold value, the anti-lock braking device works, the regenerative braking system quits the regenerative braking torque, and if the current slip rate is smaller than or equal to the threshold value, regenerative braking is carried out according to the following processes that through a proportional valve connected in a hydraulic braking loop of the hybrid electric vehicle in series, braking force distribution curves of a front brake and a rear brake are made to be piecewise linear; the braking force of the front axle and the braking force of the rear axle are obtained according to the total braking force of the whole vehicle obtained through table look-up and the curve; obtaining the magnitude of the regenerative braking torque of the front axle, the regenerative braking torque of the rear axle and the magnitude of the hydraulic braking torque at the moment k in combination with the relationship among regenerative braking torque liquid, the magnitude of the pressing braking torque at the moment k and the battery capacity attenuation influence factor vectors; the two are used for charging an automobile battery and acting on corresponding wheels respectively, and regeneration and control and distribution of hydraulic braking torque can be completed quickly and accurately.

    本发明一种混合动力汽车再生制动和防抱制动装置协调控制方法,识别当前路面类型,根据u‑s曲线求出当前路面的滑移率门限值;若当前滑移率超过门限值,防抱制动装置工作,再生制动系统退出再生制动扭矩,若小于或等于门限值,按照以下过程再生制动:通过串联在混合动力汽车液压制动回路中的比例阀,使得前、后制动器制动力分配曲线为分段线性,根据查表得到的整车总制动力大小和该曲线,得到前、后轴制动力;再结合再生制动扭矩液、压制动扭矩k时刻大小和电池容量衰减影响因素向量的关系,得到前、后轴再生制动扭矩及液压制动扭矩k时刻大小;两者分别为汽车电池充电和作用在相应车轮上,可快速准确完成再生、液压制动扭矩的控制与分配。
