Embodiment

[0058] Example: such as figure 1 Shown is the structural block diagram of the entire charging navigation decision-making system. After the navigation system receives the road congestion information transmitted from the traffic information center, it uses the speed prediction technology to predict the vehicle speed along a certain navigation route. Based on the predicted vehicle speed and The road gradient transmitted from the map information is used to calculate the predicted energy consumption during driving. These data, together with the charging pile information transmitted from the charging pile monitoring network, become the basis for the charging navigation method.

[0059] A charging navigation method of an electric vehicle charging navigation system in this embodiment includes a shortest time navigation mode, a minimum cost navigation mode and an integrated navigation mode;

[0060] When the user selects the shortest time navigation mode, perform the following steps: ...

Abstract

The invention discloses a charging navigation method of an electric vehicle charging navigation system. The charging navigation method comprises a shortest time navigation mode, a minimal cost navigation mode and an integrated navigation mode. A user can choose any navigation mode according to the own navigation needs. The charging navigation method fully considers the characteristic of the shortdriving mileage of an electric vehicle limited by the battery capacity, and is relatively close to the actual situation that a charging pile needs to be found for charging the electric vehicle in thecase of insufficient electric quantity of the electric vehicle; the cruising ability of the remaining electric quantity serves as the precondition of navigation, and thus, the condition that the destination is not reached before the electric quantity is used up is avoided; meanwhile, the different navigation requirements of an electric vehicle owner under different conditions are considered; and by setting up three different strategy modes in combination with the information of the charging pile, the decision of the optimal target charging pile is finally made, and the optimal path is planned.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging and navigation, in particular to a charging and navigation method for an electric vehicle charging and navigation system. Background technique [0002] In recent years, as resource and environmental problems have become increasingly serious, the electric vehicle industry has become an industry vigorously supported by various countries. The vehicle-mounted facilities supporting electric vehicles are also developing rapidly. Among them, the vehicle-mounted navigation system is an indispensable vehicle-mounted device in daily driving. significance. [0003] The principle of most car navigation technologies on the market today is based on the location information and road data provided by the GPS positioning system to plan the shortest path to the destination or the shortest time. This navigation strategy is no problem for ordinary fuel vehicles, but it is not suitable for electric...
