The invention discloses a hybrid electric vehicle endurance mileage calculation method and system and a hybrid electric vehicle. The hybrid electric vehicle endurance mileage calculation method comprises the steps that the initial endurance mileage in a pure oil mode when a vehicle is started is obtained; a vehicle driving mode is judged based on the current state of the vehicle, if the vehicle is in a hybrid mode, a mileage correction coefficient is obtained based on the first fuel quantity information and the corresponding driving mileage, and a first mileage reduction value is determined based on the mileage correction coefficient; if the vehicle is in the engine idling working condition mode, a second mileage reduction value in the engine idling working condition mode is obtained based on the second oil mass information and the average oil consumption information; and based on the initial endurance mileage, the first mileage reduction value and the second mileage reduction value, obtaining a residual endurance mileage, and displaying the residual endurance mileage. According to the method, the endurance display mileage value of the hybrid vehicle can be accurately obtained by combining the fuel consumption information under different working conditions.

    本申请公开了一种混动汽车续航里程计算方法、系统和混动汽车,包括:获取车辆启动时纯油模式下的初始续航里程;基于车辆当前状态判断车辆行驶模式,若车辆处于混动模式,则基于第一油量信息和对应的行驶里程,得到里程修正系数,并基于所述里程修正系数确定第一里程减少值;若车辆处于发动机怠速工况模式,则基于第二油量信息与平均油耗信息,得到发动机怠速工况模式下的第二里程减少值;基于所述初始续航里程、第一里程减少值和第二里程减少值,得到剩余续航里程,并将所述剩余续航里程进行显示。本申请可以结合不同工况的油耗信息准确得到混动汽车续航显示里程值。
