Method and device for evaluating endurance mileage of electric automobile and automobile

Abstract

The invention provides a method and device for evaluating the endurance mileage of an electric automobile and an automobile, and the evaluation method comprises the steps: obtaining an initial value of an endurance mileage evaluation parameter of an automobile at a preset time interval in the driving process of the automobile; calculating a correction value of the endurance mileage evaluation parameter according to the driving state of the vehicle in the current statistical duration; correcting the initial value according to the correction value to obtain a self-learning value of the endurance mileage evaluation parameter; and according to the self-learning value, calculating the remaining endurance mileage of the vehicle in the current statistical duration. According to the scheme, the driving habits of the user can be recognized, and the remaining driving mileage can be accurately calculated for different drivers. The problem that the remaining driving mileage of the same vehicle is not accurately calculated due to different driving habits of different drivers is solved, the driving satisfaction degree of the user is effectively improved, and the mileage anxiety of the user is relieved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an evaluation method, device and automobile for the cruising range of an electric vehicle. Background technique [0002] With the popularity of electric vehicles, users have put forward higher and higher requirements for electric vehicles. Under the current situation that charging piles are not fully popularized, compared with traditional fuel vehicles, the focus of users' attention on electric vehicles is the anxiety about the mileage, and how to effectively estimate the remaining mileage has become the key to the technological breakthrough of electric vehicles. [0003] At present, due to the different driving habits of different drivers, the calculation of the driving range will be inaccurate, and there will be a mismatch between the estimated remaining driving range and the actual driving range. That is to say, in the process of energy consumption calculation, adaptive learning of...
