The invention provides a control method and a control system for recovery of braking energy of an electric vehicle. The control method comprises the steps that the current vehicle speed of the electric vehicle is obtained; whether the current vehicle speed is smaller than the critical vehicle speed or not is judged, and if yes, an external braking request is sent to the electronic parking system; and the electronic parking system brakes the electric vehicle according to the external braking request. Compared with the mode that hydraulic braking replaces a power motor to continue to brake the electric automobile, the control method and the control system replace the power motor to continue to brake the electric automobile through the electronic parking system, the smoothness of the braking process is improved, and noise vibration in the braking process is reduced.

    本申请提供一种电动汽车制动能量回收的控制方法和控制方系统。该控制方法包括步骤:获取电动汽车的当前车速;判断当前车速是否小于临界车速,若判断结果为是,向电子驻车系统发送外部制动请求;电子驻车系统根据所述外部制动请求对电动汽车进行制动。相比较于通过液压制动接替动力电机继续对电动汽车进行制动,本申请的控制方法和控制方系统通过电子驻车系统接替动力电机继续对电动汽车进行制动,提高了制动过程的平顺性,以及降低了制动过程的噪声振动。
