The invention discloses a range extender control method based on road information and a range-extended electric vehicle. The control method comprises the steps of providing multiple pieces of stored road information and multiple working parameters of a range extender; judging whether the road information of the travel starting point is stored or not; when the road information are determined to be stored, enabling the range extender to work according to the working parameters; monitoring a real-time SOC value of a battery, and when the real-time SOC value is smaller than the starting SOC value of the range extender, increasing the real-time working power of the range extender; when the vehicle travels to the end point of the travel, calculating the actual energy consumption of the whole vehicle in the travel; judging whether the actual vehicle energy consumption is greater than the expected vehicle energy consumption or not; if so, obtaining new working parameters of the range extender through calculation; and updating and storing the new working parameters corresponding to the road information. According to the range extender control method and the range-extended electric vehicle, self-adjustment is carried out based on the road information, oil consumption is further reduced, meanwhile, the problem that the rotating speed of the range extender is suddenly increased possibly is avoided, and the NVH performance of the whole vehicle is further optimized.

    一种基于道路信息的增程器控制方法及增程式电动汽车,所述控制方法包括:提供所存储的多个道路信息和增程器的多个工作参数;判断行程起始点的道路信息是否已存储;当确定已存储时,以所述工作参数控制所述增程器工作;监测电池的实时SOC值,当所述实时SOC值小于所述增程器启动SOC值时,提高增程器的实时工作功率;当行驶至行程终止点时,计算所述行程的实际整车能耗;判断实际整车能耗是否大于预期整车能耗;当判断大于时,计算得到增程器的新工作参数;更新并存储所述道路信息对应的新工作参数。上述增程器控制方法及增程式电动汽车,基于道路信息自我调节,进一步降低油耗,同时,避免可能出现的增程器转速突然升高的问题,进一步优化整车NVH性能。
