：Currently, the researches on the control algorithms of regenerative braking force of electricvehicles are mainly locused on the brake-torce distribution control algorithms. In this paper, a dynam- ic coordinated control algorithm of braking force is presented. The algorithm uses feedforward andfeedback control, and its control objective is to make the total brake of the mechanical braking system and motor braking system meet the needs of the driver as much as possible, reduce the rate of the ve-hicle deceleration change, and ensure the smoothness of the vehicle braking. The test results show that the control strategies can meet the needs of the driver and ensure the smoothness of the braking process.
