The invention discloses a remaining mileage determination method and device. The method comprises the steps that a vehicle energy consumption model, the remaining electric quantity of a vehicle, attribute data and driving data are obtained, the driving data comprise the vehicle speed, the axle load and the outer wheel steering angle, and the vehicle energy consumption model is a fusion model obtained by fusing a steering system energy consumption model and a vehicle longitudinal dynamics energy consumption model; calculating steering energy consumption based on the attribute data and the driving data through a steering system energy consumption model; calculating longitudinal energy consumption based on the attribute data and the vehicle speed through a vehicle longitudinal dynamic energy consumption model; calculating the sum of the steering energy consumption and the longitudinal energy consumption to obtain the energy consumption of the whole vehicle; and determining a target remaining mileage corresponding to the whole vehicle energy consumption and the remaining electric quantity according to the corresponding relationship among the whole vehicle energy consumption, the remaining electric quantity and the remaining mileage. According to the remaining mileage determination method provided by the embodiment of the invention, the accuracy of the remaining mileage can be improved.
