The invention discloses a new energy automobile mileage calculation method. The method is suitable for new energy vehicles. Even if the data packet is lost, current mileage information of the automobile can be accurately obtained, so that the automobile mileage calculation precision can be greatly improved. The method comprises the following steps: acquiring vehicle data and uploading the vehicledata in real time; obtaining and uploading in real time the vehicle state; calculating and storing driving mileage information of the automobile in the current vehicle state; vehicle key opening moment; the moment when the vehicle is started by a key, acquiring a current starting mileage Sstart; when the vehicle key is in a continuous start state, acquiring a cumulative mileage Scurrent, and calculating a current mileage Ssegment (N)=Scurrent (N)-Sstart; judging whether a vehicle generates displacement in a mileage section or not, and judging whether data packet loss occurs or not in real time; and performing calibration by adopting a data verification method when data packet loss occurs.

    本发明公开了一种新能源汽车行驶里程计算方法,其可适用于新能源汽车,即使在数据丢包时,也可准确获取汽车当前行驶里程信息,可大大提高汽车行驶里程计算精度,该方法包括:获取整车数据并实时上传,获取并实时上传车辆状态,计算并存储当前车辆状态下汽车的行驶里程信息,车钥匙开启瞬间,获取当前开始行驶里程:Sstart,车钥匙持续启动状态时,获取累积行驶里程Scurrent,计算当前行驶里程Ssegment(N)=Scurrent(N)‑Sstart,判断车辆在该行驶里程段内是否产生位移,实时判断是否有数据丢包,当发生数据丢包时,采用数据校验合法进行校准。
