The invention discloses a cooperative control method for self-adaptive cruise and regenerative braking of an electric vehicle. The cooperative control method comprises the steps that 1, a kinematic model of the vehicle is established, and performance indexes and constraint conditions are set; 2, solving the established target function by adopting a dynamic programming algorithm; 3, taking the solved result as the input of a regenerative braking control system; and 4, constraint of the motor and the battery is set, and distribution of braking force is achieved. According to the invention, two technical schemes of self-adaptive cruise and regenerative braking are combined, so that the self-adaptive cruise and regenerative braking reflect respective performances, and more braking energy is recovered while the intelligent electric vehicle meets the comprehensive driving performance.

    发明公开了一种电动汽车自适应巡航与再生制动的协同控制方法,其步骤包括:1、建立车辆的运动学模型并设定性能指标以及约束条件;2、采用动态规划算法对建立的目标函数进行求解;3、将求解后的结果做为再生制动控制系统的输入;4、设定电机和电池的约束,实现制动力的分配。本发明将自适应巡航和再生制动两种技术方案相结合,使其体现各自应有的性能,保证智能电动汽车满足综合行驶性能的同时回收更多的制动能量。
