The invention provides a regenerative braking and anti-lock braking control system. A vehicle includes an electric machine, friction brakes, a drivetrain, and a controller. The electric machine is configured to recharge a battery during regenerative braking. The friction brakes are configured to apply torque to wheels of the vehicle to slow the vehicle. The controller is programmed to, in response to and during an anti-locking braking event, generate a signal indicative of a total torque demand to brake the vehicle based on a difference between a desired wheel slip ratio and an actual wheel slip ratio, adjust a regenerative braking torque based on a product of the signal and a regenerative braking weighting coefficient, adjust a friction braking torque based on a product of the signal and a friction braking weighting coefficient, and further adjust the regenerative braking torque based on a closed-loop control of an estimated regenerative braking torque feedback.

    本公开提供了“再生制动/防抱死制动控制系统”。一种车辆包括电机、摩擦制动器、传动系以及控制器。所述电机被配置为在再生制动期间对电池再充电。所述摩擦制动器被配置为向所述车辆的车轮施加扭矩以使所述车辆减速。所述控制器被编程为响应于防抱死制动事件并且在所述防抱死制动事件期间,基于期望的车轮滑移率与实际的车轮滑移率之间的差值而生成指示制动所述车辆的总扭矩需求的信号;基于所述信号与再生制动加权系数的乘积来调整所述电机的再生制动扭矩;基于所述信号与摩擦制动加权系数的乘积来调整所述摩擦制动器的摩擦制动扭矩;以及基于闭环控制来进一步调整所述电机的所述再生制动扭矩。
