The invention provides an intelligent control method for a driving mode of a pure electric commercial vehicle. The intelligent control method comprises the steps that S1, torque of a Normal mode and torque of an ECO mode are calibrated; s2, accelerator torque Map maps of the Normal mode and the ECO mode are determined according to the product of different accelerator opening degrees and the maximum driving torque, and the accelerator torque Map maps are stored in a vehicle control unit; s3, the actual slope d of the current road is obtained, and the accelerator change rate delta K of an accelerator pedal is collected and calculated in real time; and S4, switching the driving mode according to d and delta K. According to the method, a proper driving mode can be comprehensively selected according to subjective operation of a driver and objective road factors, and the driving intention can be better judged under the condition that the driving intensity of driving is relieved, so that the energy consumption of the commercial vehicle is reduced as much as possible on the premise that the dynamic property is kept. The mode can effectively solve the problem of contradiction between power and economy in mountainous areas and urban areas.
本发明提供一种纯电动商用车驱动模式的智能控制方法,包括:S1、对Normal模式和ECO模式的扭矩进行标定;S2、根据不同的油门开度和最大驱动扭矩的乘积,来确定Normal模式和ECO模式的油门扭矩Map图,并将油门扭矩Map存储到整车控制器中;S3、获取当前道路的实际坡度d,实时采集并计算油门踏板的油门变化率ΔK;S4、根据d和ΔK对驱动模式进行切换。本发明可根据驾驶员的主观操作和道路客观因素综合选取合适的驾驶模式,在减轻驾驶的驾驶强度情况下,能更好的对驾驶意图进行判断,从而达到保持动力性的前提下尽可能多的降低商用车能耗。该模式在山区和市区均能有效处理动力和经济性的矛盾问题。
