Embodiment Construction

[0040] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0041] The route search device shown in this embodiment performs wireless communication with a navigation server located at a remote location, and searches a plurality of routes from the current location to a destination. In addition, the route search device exchanges information with the electronic control unit (ECU, Electronic Control Unit) installed on the electric vehicle and used to control the vehicle through a bus interface such as USB, and obtains the remaining battery capacity of the vehicle (electric vehicle) And vehicle information such as air-conditioning temperature settings. Then, based on the vehicle information, the comfort level when driving along each route is evaluated from the viewpoints of power consumption and cabin temperature, etc., and some "route and action settings (driving mode settings) with high comfort level are displayed on...

Abstract

The invention provides a route planning device. The route planning device evaluates the comfort levels obtained when the vehicle travels along each of the routes on the basis of the vehicle information in terms of power consumption and a room temperature. Thus, the driver can select one of the operation plans that is the most comfortable from the driver's point of view. The route planning device includes a processing unit (10). The processing unit (10) includes a route planner (40), a driving power calculator (42), an AC power calculator (44), an SOC calculator (46), a comfort level calculator (48), an operation plan selector (50), a setting changer (52), and a setting change detector (54).

Description

technical field [0001] The invention relates to a route search device for a vehicle, in particular to a route search device for an electric vehicle using a battery. Background technique [0002] An electric vehicle has a rechargeable battery and an electric motor, which is powered by the battery to drive the vehicle. This electric vehicle has some problems to be solved that are different from conventional vehicles using internal combustion engines. [0003] For example, it is difficult for electric vehicles to ensure the battery capacity with the same cruising distance as current gasoline vehicles. In addition, the use of air conditioners and other power-consuming devices will greatly reduce the cruising distance of electric vehicles. In addition, when using a driving mode that prioritizes acceleration performance, the cruising distance of the electric vehicle in this driving mode will also be shortened along with the increase in power consumption during acceleration. That...
