The invention discloses a gear shifting reminding method for pure electric vehicles. A shifter sends a digital signal to a vehicle controller according to the actual operation result of a driver; thevehicle controller judges whether the shifting condition is met or not according to the vehicle status at the moment; if the condition is met, a correct gear signal is sent to a combination instrument; if the condition is not met, a signal of a gear shifting failure state is sent to the combination instrument; the combination instrument receives the gear information sent by the vehicle controllerand carries out the corresponding gear shifting reminding. According to the technical scheme, corresponding sound reminding can be made for the pure electric vehicle when the gear shifting is successful or failed, the problem that the vehicle cannot be powered on due to the inconsistent initial position of gears before the high voltage is applied is solved, and the safety accident caused by no power output when the vehicle is not shifted to the correct gear during normal driving is solved.

    本发明公开了一种纯电动汽车挡位切换提醒方法,换挡器根据驾驶员实际操作的结果,发送数字信号到整车控制器;整车控制器根据此时车辆状态,判断是否满足换挡条件;如果满足,则发送正确挡位信号到组合仪表;如果不满足,则发送挡位切换失败状态的信号到组合仪表;组合仪表接收整车控制器发送挡位信息并进行相应的挡位切换提醒。采用上述技术方案,为纯电动汽车在档位切换成功与失败时做出相应的声音提醒,解决车辆在上高压前档位初始位置不一致导致无法上电的问题,以及解决正常行驶时未切换到正确档位时无动力输出导致发生安全事故的问题。
