The invention relates to the technical field of electric vehicle control, in particular to a driving mode switching method for an extended-range electric vehicle, the extended-range electric vehicle comprises an instrument end, an instrument panel is provided with a display panel of driving modes, a hardware switch is mounted on a center console of a cab, one end of the hardware switch is connected with a low-voltage storage battery, and the other end of the hardware switch is connected with a power supply. One end of the VCU is connected with a hardware switch, the other end of the VCU is connected with a hardware pin of the VCU, a hardware driving module of the VCU detects a rising edge of the hardware switch, the VCU sends an actual driving mode of the system to a gateway through a bus and then forwards the actual driving mode to an instrument end, and the instrument end displays the actual driving mode of the system in real time after receiving the actual driving mode. A driver dynamically adjusts the expected driving mode through the actual driving mode displayed by the instrument end, and the problems that although the HMI can achieve various intelligent interaction functions, for economical vehicle types, the cost is high, the applicability is low, and the production and manufacturing cost is increased are solved.

    本发明涉及电动汽车控制技术领域,具体地说,本发明涉及一种增程式电动汽车驱动模式切换方法,增程式电动汽车包括有仪表端,仪表盘设置有驱动模式的显示面板,在驾驶室中控台上安装有硬件开关,硬件开关一端与低压蓄电池相连,另一端连接VCU的硬件针脚,VCU的硬件驱动模块检测所述硬件开关的上升沿,所述的VCU将系统的实际驱动模式通过总线发给网关然后转发至仪表端,仪表端接收后实时显示系统实际驱动模式,驾驶员通过仪表端显示的实际驱动模式来动态调整期望的驱动模式,解决了HMI虽然能实现各种智能交互功能,但是对于经济型车型来讲,成本较高,适用性较低,提高了生产制造的成本的问题。
