The invention discloses an auxiliary control method and system for preventing an electric automobile from sliding on a slope and an automobile, and the method comprises the following steps: under the condition that an anti-sliding function I is activated, if the absolute value of the slope is less than or equal to S1, determining a first torque T1, and requesting a control motor to smoothly output the first torque T1, otherwise requesting an electronic parking brake system to keep clamping. Under the condition that the anti-slip function II is activated, if the brake pedal is stepped on to activate the ramp assisting function and release the brake pedal, a second torque T2 is determined, and the motor is requested to be controlled to continuously and smoothly output the second torque T2 within t0; and if the ramp assist function is not activated by stepping on the brake pedal, a third torque T3 is determined, and the control motor is requested to smoothly output the third torque T3. And under the condition that the slope sliding prevention function quitting condition is met, the slope sliding prevention function is quitted. The reliability of the anti-slip function can be improved, the driving comfort and safety of a driver on a ramp are improved, and the ramp starting experience of different driving modes is improved.

    本发明公开了一种防止电动汽车溜坡的辅助控制方法、系统及车辆,其在激活防溜坡功能Ⅰ的情况下,若坡度的绝对值小于或等于S1,则确定第一扭矩T1,并请求控制电机平滑输出第一扭矩T1,否则请求电子驻车制动系统保持夹紧。在激活防溜坡功能Ⅱ的情况下,若踩制动踏板激活坡道辅助功能并放开制动踏板,则确定第二扭矩T2,并请求控制电机在t0内持续且平滑输出第二扭矩T2;若踩制动踏板未激活坡道辅助功能,则确定第三扭矩T3,并请求控制电机平滑输出第三扭矩T3。在满足防溜坡功能退出条件的情况下,退出防溜坡功能。其能增加防溜坡功能的可靠性,提高驾驶员在坡道上开车的舒适性与安全性,提升不同的驾驶方式的坡道起步体验。
