摘要： Disclosed are a method and system for braking energy feedback control in a pure electric vehicle using a combination of electric braking and mechanical braking, with the electric braking being accomplished by controlling the operation of an electric motor in a power generating state and the mechanical braking being carried out by an electronic braking system. A vehicle control unit is the core control unit in the system for braking energy feedback control, said vehicle control unit being used for calculating the braking torque required from the electric motor and the braking force required from the electronic braking system, and for sending control commands to the control circuitry of an electric motor controller and to the electronic braking system, respectively. The present method and system satisfy the braking requirements of the vehicle under all working conditions, while also ensuring stability of vehicle operation and smoothness of vehicle braking deceleration, and at the same time enabling braking energy to be recovered in the most effective way, thus improving the overall effectiveness of vehicle energy utilization.
