Determining method and device of driving mileage, and vehicle

Abstract

The invention provides a determining method and device of the driving mileage, and a vehicle, and relates to the technical field of vehicles. According to the determining method and device of the driving mileage, and the vehicle, after the vehicle enters into a charging mode, the first driving mileage used for instrument display of the previous period and the second driving mileage corresponding to a first preset gear of the previous period are obtained periodically, and thus the deviation mileage is obtained; and when the deviation mileage is larger than a first preset value, it is presentedthat display of the driving mileage needs to be optimized currently, thus the target driving mileage used for instrument display is not jumped obviously, and the accuracy degree of the driving mileageis increased.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method, device and vehicle for determining driving range. Background technique [0002] The mileage display strategy is an important control strategy for new energy vehicles, which can be intuitively felt by the user, reminding the user of the remaining mileage that can be driven, and providing guarantee for the user's travel. In the process of designing the control strategy, not only the accuracy of the mileage display, but also the comfort of the user should be considered. [0003] The current mainstream new energy vehicle gears include: Parking gear P / Neutral gear N / Reverse gear R / Forward gear D / E / S, among which E gear belongs to economic gear, S gear belongs to sports gear, these two gears display The mileage displayed in the P / N / R / D gear will be different from the mileage displayed in the P / N / R / D gear. During the gear switching process, the mileage display strategy wi...

[0003] The current mainstream new energy vehicle gears include: Parking gear P / Neutral gear N / Reverse gear R / Forward gear D / E / S, among which E gear belongs to economic gear, S gear belongs to sports gear, these two gears display The mileage displayed in the P / N / R / D gear will be different from the mileage displayed in the P / N / R / D gear. During the gear switching process, the mileage display strategy will often cause the mileage to jump

Especially after entering the charging mode, the mileage in the related art is determined according to the gear before charging. If the S gear is used before charging, the driving mileage after full charging will be significantly lower than the D gear mileage, thereby causing unforeseen consequences to the user. Trouble with full charge or excessive battery loss, reducing user experience
