The invention relates to the field of electric vehicle ramp assistance, and discloses an electric vehicle ramp stability control method which comprises an anti-slip module with a brake signal, the anti-slip module with the brake signal judges slip information with the brake signal, and if all slip information with the brake signal is met, the method enters; presetting the maximum number of allowable band brake entering the anti-slip module; the driving motor outputs torque, the rear sliding distance and the rear sliding rotating speed of the whole vehicle are reduced, and the rotating speed value of the driving motor is controlled to be lower than the first rotating speed; when the parking state of the output torque of the driving motor is kept to be equal to the first parking time, subtracting 1 from the allowable frequency of the belt brake entering the anti-slip module; and judging whether a band brake quit condition for quitting the anti-slip module with the band brake signal is met or not, and quitting if one of the conditions is met. By arranging the anti-slip module with the brake signal, the driver used to slowly loosen the brake pedal is prevented from mistakenly exiting the anti-slip module, and the safety of hill starting is improved.
本发明涉及电动车坡道辅助领域,公开了一种电动车坡道稳定控制方法,包括带制动信号的防溜坡模块,带制动信号的防溜坡模块包括对带制动信号的溜坡信息进行判定,若全部满足,则进入;预设允许的带制动进入防溜坡模块的最大次数;驱动电机输出扭矩,减小整车后溜距离和后溜转速,驱动电机转速值控制至低于第一转速;当驱动电机输出扭矩保持驻停状态等于第一驻停时间时,将允许的带制动进防溜坡模块的次数减1;判断是否满足退出带制动信号的防溜坡模块的带制动退出条件,若满足之一,即退出。通过设置带制动信号的防溜坡模块,避免习惯于缓慢松开制动踏板的驾驶员误退出防溜坡模块,提高坡道起步的安全性。
