Method and system for planning optimal route and optimal driving mode of electric automobile

Abstract

The invention discloses a method and a system for planning an optimal route and an optimal driving mode of an electric automobile. The method comprises the following steps: based on reachability analysis, performing sieving so as to obtain a practicable route set of the electric automobile under different driving modes and a corresponding charging mode set; after a user weight coefficient is obtained, calculating evaluation indexes of each practicable route under different driving modes, wherein the user weight coefficient is the coefficient preset by a user or is the coefficient which is automatically obtained according to the driving habits of the user; and based on the calculated evaluation indexes, planning the optimal route and the optimal driving mode. Through the adoption of the method disclosed by the invention, according to the demand indexes of the user, the evaluation indexes of corresponding weighting are calculated, so that the optimal practicable route, and the optimal driving mode, namely the combination of a driving mode and an air conditioner mode are obtained through sieving; and automobile characteristics of the electric automobile can be sufficiently utilized, so that the optimal route planning result and the optimal driving mode planning result are obtained, the optimizing result is good, and the method can be widely applied in the control field of the electric automobile.

Description

technical field [0001] The invention relates to the field of control of electric vehicles, in particular to a planning method and system for optimal routes and driving modes of electric vehicles. Background technique [0002] The mileage of electric vehicles is limited. For long-distance driving or continuous driving when the battery is low, it is necessary to consider the charging demand when planning the route to eliminate the user's mileage anxiety. At the same time, the influence of driving conditions must also be considered. In addition, the driving mode of electric vehicles includes driving mode and air-conditioning mode. The driving mode will affect the power consumption of electric vehicles, which has an important impact on the driving range of electric vehicles. Appropriate driving mode planning can extend the driving range of vehicles. In the prior art, some methods have been used to plan the vehicle’s driving path according to the number of charging stations in th...

Problems solved by technology

In the prior art, some methods have been used to plan the vehicle’s driving path according to the number of charging stations in the driving path of the vehicle. However, these methods focus on meeting the charging requirements of electric vehicles, and do not comprehensively consider the driving process. The impact of the method on the power consumption of electric vehicles is relatively single, and various vehicle characteristics of electric vehicles cannot be fully utilized, and the optimization results are not ideal
