The invention relates to the technical field of automobiles, and provides a range extender control method and device based on driving mileage and a range extending type electric automobile. The method comprises the following steps: when a total mileage is greater than a pure electric mileage, calculating a smooth proportion and a congestion proportion based on the total mileage, a congestion mileage and a smooth mileage; determining a first power generation weight of the unblocked mileage based on the unblocked proportion, and determining a second power generation weight of the congestion mileage based on the first power generation weight; according to the total power generation amount, the first power generation weight and the second power generation weight, calculating a first power generation amount of unblocked mileage and a second power generation amount of congested mileage; according to the first power generation amount, the second power generation amount, the unblocked ratio, the congestion ratio and the total time, calculating first power generation power of the unblocked mileage and second power generation power of the congestion mileage; and in the unblocked mileage, a range extender of the range-extended electric vehicle is controlled to generate power according to the first generated power, and in the congested mileage, the range extender of the range-extended electric vehicle is controlled to generate power according to the second generated power.

    本申请涉及汽车技术领域,提供了一种基于驾驶里程的增程器控制方法、装置及增程式电动汽车。该方法包括:当总里程大于纯电里程时:基于总里程、拥堵里程和畅通里程计算畅通占比和拥堵占比;基于畅通占比确定畅通里程的第一发电权重,基于第一发电权重确定拥堵里程的第二发电权重;根据总发电量、第一发电权重和第二发电权重,计算畅通里程的第一发电量和拥堵里程的第二发电量;根据第一发电量、第二发电量、畅通占比、拥堵占比和总时间,计算畅通里程的第一发电功率和拥堵里程的第二发电功率;在畅通里程中,控制增程式电动汽车的增程器按照第一发电功率发电,在拥堵里程中,控制增程式电动汽车的增程器按照第二发电功率发电。
