The invention discloses a control method suitable for switching driving modes of a new energy commercial vehicle, relates to the technical field of new energy commercial vehicles, and solves the problems that fluctuation exists in the existing driving mode switching process, switching of the driving modes cannot be adaptively adjusted according to the condition that the current electric quantity of a power battery is insufficient, and energy saving and environment protection cannot be optimized. According to the method, an ECO mode, an NORMAL mode and an SPORT mode are defined; an SCU outputs a driving torque coefficient of a corresponding mode to a torque module; the torque module outputs a torque request signal to an IC, a VCU collects a KEY signal to recognize the current ignition state of a vehicle, the SCU sends driving mode request information to the torque module in the VCU through the CAN bus, and the VCU finally determines the current driving mode according to the current power battery SOC value sent by the BMS and outputs the current driving mode to the IC to be displayed. According to the control method, the corresponding driving modes are reasonably selected according to different driving road conditions, and the comfortable driving feeling is improved.

    一种适用于新能源商用车驾驶模式切换的控制方法,涉及新能源商用汽车技术领域,解决现有驾驶模式切换过程中存在波动现象,且不能根据动力电池当前电量不足的情况进行适应性调整驾驶模式的切换,以及不能最大化的做到节能环保等问题,本发明定义ECO模式、NORMAL模式和SPORT模式;SCU向扭矩模块输出对应模式的驱动力矩系数;所述扭矩模块向IC输出扭矩请求信号,VCU采集KEY信号识别车辆当前的点火状态,SCU通过CAN总线向VCU内部的扭矩模块发送驾驶模式请求信息,VCU根据BMS发送的当前动力电池SOC值,最终确定当前的驾驶模式,并输出至IC进行显示;本发明所述的控制方法根据不同的行驶路况合理选择相应的驾驶模式,提升舒适的驾驶感受。
