The invention discloses an intelligent auxiliary starting method and system for an electric vehicle. The intelligent auxiliary starting system comprises a ramp detection module; a control module; a torque determination module; an uphill auxiliary adjusting module; when the ramp detection module recognizes that the road surface where the electric automobile is located is in an uphill state, gradient data of the current position where the electric automobile is located is transmitted back to the control module, and the control module judges whether the uphill auxiliary function of the electric automobile is started or not according to the current automobile speed, the gear state, the brake pedal opening degree and the hand brake state of the electric automobile. The torque determination module calculates a starting basic torque and a reserve torque required by the current electric vehicle through a preset program, and the uphill auxiliary adjustment module controls a motor of the electric vehicle to output a corresponding torque according to the corresponding starting basic torque and the reserve torque; according to the method and the system, the situation that wheels of the electric automobile idle on the ramp due to the fact that a driver excessively steps on the accelerator pedal can be effectively avoided, and the safety performance of the electric automobile in the uphill process is effectively improved.

    本发明申请公开了一种电动汽车智能辅助启动方法与系统,包括:坡道检测模块;控制模块;扭矩确定模块;上坡辅助调节模块;通过坡道检测模块识别电动汽车所处的路面状态为上坡时,将当前电动汽车所处位置的坡度数据回传至控制模块中,控制模块结合电动汽车当前的车速、档位状态、制动踏板开度以及手刹状态,判断电动汽车的上坡辅助功能是否开启,扭矩确定模块通过预设程序计算当前电动汽车所需的起步基础扭矩和储备扭矩,上坡辅助调节模块则根据相应的起步基础扭矩和储备扭矩控制电动汽车的电机输出相应的扭矩;本方法与系统能够有效地避免驾驶人过度踩踏油门踏板,造成电动汽车的车轮在坡道上空转,有效地提高电动汽车上坡时的安全性能。
