The invention discloses an electric vehicle electronic parking switch control method and system, and the method comprises the steps: obtaining an input voltage signal of an electronic parking controller in response to a parking request signal; according to a preset floating voltage range, whether the input voltage signal is valid or not is judged, if yes, current driving state data are obtained, whether a current vehicle meets a parking condition or not is judged, and if yes, parking control is executed; wherein the step of judging whether the input voltage signal is effective or not comprises the substeps that the input voltage signal is compared with the floating voltage range, and if the input voltage is within the floating voltage range, the input voltage signal is effective; if the input voltage signal is smaller than the minimum value of the floating voltage interval and larger than a preset minimum voltage threshold value, the input voltage signal is valid. By setting the floating voltage interval and fuzzifying the threshold boundary, the recognition degree of the effective small voltage is improved, and the reliability of electronic parking is improved.

    本发明公开了一种电动汽车电子驻车开关控制方法及系统,所述方法包括:响应于驻车请求信号,获取电子驻车控制器的输入电压信号;根据预设的浮动电压范围,判定所述输入电压信号是否有效,若有效,获取当前行车状态数据,判定当前车辆是否满足驻车条件,若满足,执行驻车控制;其中,判定所述输入电压信号是否有效包括:将所述输入电压信号与所述浮动电压范围进行比对,若所述输入电压在所述浮动电压区间内,所述输入电压信号有效;若所述输入电压信号小于所述浮动电压区间的最小值,且大于预设的最小电压阈值,所述输入电压信号有效。通过设定浮动电压区间,并模糊阈值边界,提高了有效偏小电压的识别度,提高了电子驻车的可靠性。
