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

Abstract

The invention discloses a planning method and system for an optimal route and driving mode of an electric vehicle. The method comprises the steps of: based on reachability analysis, screening and obtaining feasible route sets and corresponding charging mode sets of electric vehicles under different driving modes. ; After obtaining the user weight coefficient, calculate the evaluation index of each feasible path under different driving modes; the user weight coefficient is a coefficient preset by the user or automatically obtained according to the user's driving habits; based on the calculated evaluation index, optimize Path and driving style planning. The present invention can calculate the corresponding evaluation index according to the demand index of the user, thereby screening and obtaining the optimal feasible route and the combination of the driving mode and the air-conditioning mode, and can make full use of the vehicle characteristics of the electric vehicle to obtain the optimal route planning And driving style planning results, the optimization results are good, and can be widely used in the field of electric vehicle control.

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...
