The invention provides a pure electric commercial vehicle driving strategy which comprises the following steps: dividing a mass interval between full-load mass and no-load mass of a vehicle into N load-carrying intervals, and respectively calibrating torque MAP of each load-carrying interval; the whole vehicle controller calculates the actual load mass of the vehicle in real time; the vehicle control unit selects a corresponding torque MAP according to the load interval where the actual load mass is located; the vehicle control unit obtains the maximum dischargeable power of the power battery in real time; and the vehicle control unit calculates output power in real time according to the currently selected torque MAP, compares the output power with the maximum dischargeable power, and sends a corresponding torque signal to a motor controller according to a comparison result, so that the motor controller controls a motor to output corresponding torque. According to the driving strategy of the pure electric commercial vehicle, different driving MAPs can be selected and used according to the actual load condition of the vehicle, and therefore the energy consumption of the vehicle can be effectively reduced.
本发明提供了一种纯电动商用车驱动策略，其包括以下步骤：将车辆的满载质量与空载质量之间的质量区间分为N个载重区间，分别标定出各载重区间的扭矩MAP；整车控制器实时计算车辆的实际载重质量；整车控制器根据实际载重质量所在的载重区间，选取相应的扭矩MAP；整车控制器实时获取动力电池的最大可放电功率；整车控制器根据当前选取的扭矩MAP，实时计算输出功率，并将该输出功率与上述最大可放电功率进行比对，根据比对结果发送相应的扭矩信号给电机控制器，使得电机控制器控制电机输出相应的扭矩。本发明的纯电动商用车驱动策略，其能够根据车辆的实际载重情况，选择使用不同的驱动MAP，从而能够有效地降低车辆的能耗。
