Method and device used for calculating electric vehicle endurance mileage

Abstract

The invention discloses a method and device used for calculating electric vehicle endurance mileage. The method comprises the following steps of a, obtaining a position and information; b, obtaining a planning path; c, conducting point-to-point matching on the planning path and geological information in a route searcher, wherein the obtained planning path is input into the route searcher, and the planning path and the geological information in the route of the route searcher are subjected to point-to-point matching to obtain matched road sections and / or non-matched road sections; d, calculating and displaying the endurance millage, wherein through the matched road sections and / or the non-matched road sections, total power consumption of the planning path is calculated, the total power consumption and current battery remaining capacity are compared, whether driving of the planning path can be completed with the battery remaining capacity or not is calculated, and whether driving of the planning path can be completed or not is displayed in a display device. Comparing with an existing endurance millage calculation method and the method for calculating the electric vehicle endurance mileage, the precision is higher, and the result is more accurate.

Description

technical field [0001] The invention belongs to the technical field of calculating the driving range of a vehicle, in particular relates to calculating the driving range of an electric vehicle, in particular to a method and a device for calculating the driving range of an electric vehicle. Background technique [0002] A pure electric vehicle needs to provide the driver with how much mileage can be driven by the energy stored in the current battery of the car, and providing this result requires the calculation of the driving mileage. [0003] The currently known method for calculating the mileage is to divide the car according to the remaining power of the battery and the current transient power consumption of the car or the average power consumption of the car from a certain time in the past to the current period of time to obtain a Driving time, the result of multiplying the driving time by the current speed or the average speed of the car during a period from a certain ti...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, solve the problem that the calculation of the driving distance of the existing vehicle cannot be based on the power consumption of the road section the vehicle will drive, and cause inaccurate results, and propose a method for calculating the electric vehicle. A method and device for driving range, which can be based on the driving route of the destination planned by the electric vehicle through the navigation device, and combined with the energy consumption information of the past driving on a specific road section in the driving route to calculate the electric vehicle mileage
