Vehicle control unit, vehicle and remaining driving range display method and device of vehicle

Abstract

The invention discloses a vehicle control unit, a vehicle and a remaining driving range display method and device of the vehicle. The method comprises the steps that: a current SOC value of a power battery is detected; a current remaining driving range calculation value and a remaining driving range display reference value are obtained, so that a range difference value between the current remaining driving range calculation value and the remaining driving range display reference value can be obtained; according to the current SOC value, the difference value and a first relationship, an updatedrate of the corresponding remaining driving range display reference value under the current SOC value and the difference value is obtained, wherein the first relation is the relation among the SOC value, the range difference value and the updated rate of the remaining driving range display reference value. According to the method, the updated rate of the remaining driving range display referencevalue under the current SOC value and the difference value can be obtained according to the current SOC value and the difference value, calculation accuracy is effectively improved, the practicabilityand applicability of the vehicle are improved, and the use experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle controller, a vehicle and a method and device for displaying remaining mileage thereof. Background technique [0002] In related technologies, the control algorithm for displaying the remaining driving range of the vehicle is relatively simple. During charging, the remaining driving range display increases with the increase of SOC (State of Charge, state of charge), and the fully charged driving range is displayed at the end of charging. [0003] However, the related technology only considers that the remaining mileage during charging only increases with the increase of SOC, and does not consider the influence of temperature, battery health status, and battery consistency on the driving ability of the vehicle, which may easily lead to large calculation errors. The accuracy of the calculation is reduced, and the problem that the existing power cannot guarantee the vehic...

Problems solved by technology

[0003] However, the related technology only considers that the remaining mileage during charging only increases with the increase of SOC, and does not consider the influence of temperature, battery health status, and battery consistency on the driving ability of the vehicle, which may easily lead to large calculation errors. The accuracy of the calculation is reduced, and the problem that the existing power cannot guarantee the vehicle to reach the destination is prone to occur, which not only reduces the practicability and applicability of the vehicle, but also reduces the user experience, which needs to be solved
