The present disclosure provides systems and methods for automatically applying braking and performing regenerative braking during downhill motion. The method may include determining states of an accelerator pedal and a brake pedal of the vehicle; when the accelerator pedal and the brake pedal are in the closed state, the set speed of the vehicle is set to be equal to the current speed of the vehicle; determining whether a value obtained by subtracting the set speed from the current speed is greater than a threshold speed of the vehicle; setting a target speed of the vehicle to be equal to a sum of the set speed and a threshold speed when a value obtained by subtracting the set speed from the current speed is greater than the threshold speed; regenerative braking is performed on a vehicle with a brake controller, with a disturbance observer (DOB) structure and a feedback controller to maintain a target speed.

    本公开提供在下坡运动期间自动施加制动并执行再生制动的系统和方法。该方法可以包括:确定车辆的加速踏板和制动踏板的状态;当加速踏板和制动踏板的状态为关闭时,将车辆的设定速度设定为等于车辆的当前速度;确定当前速度减去设定速度的值是否大于车辆的阈值速度;当当前速度减去设定速度的值大于阈值速度时,将车辆的目标速度设定为等于设定速度和阈值速度之和;利用制动控制器,利用干扰观测器(DOB)结构和反馈控制器对车辆执行再生制动,以保持目标速度。
