System and method for calculating dte when setting a navigation path

Abstract

The present invention provides a method for calculating a driving range (DTE) when setting a navigation route. The method includes receiving a route search condition from the navigation and determining whether the transmitted route search condition is a route cancellation, vehicle arrival at a destination, or a navigation search route. The method determines whether the sent route search condition is an initial setup route condition or a reset route condition. When the route search condition sent is not the above, the method determines whether there is a current guide. When initially setting a route in a route search situation, resetting a route thereafter, or currently guiding a route, displaying the DTE reflecting the route through navigation; and after displaying the DTE reflecting the route, calculating the DTE reflecting the route in real time and calculating the reflected route estimated fuel efficiency.

Description

[0001] Cross References to Related Applications [0002] This application is based upon and claims the benefit of priority from Korean Patent Application No. 10-2016-0096709 filed with the Korean Intellectual Property Office on July 29, 2016, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present disclosure relates to a system and method for calculating a cruising range (DTE) when setting a navigation route, and more particularly, to a technique for recalculating and displaying the DTE based on a change in route setting in navigation. Background technique [0004] Currently, electric vehicles, which are considered to be the future of the vehicle industry, have insufficient charging infrastructure compared to existing gasoline / diesel / hybrid vehicles, and electric vehicles cannot provide accurate information to drivers based on remaining battery power during electric vehicle driving. provide cruising range (DTE) accur...

Problems solved by technology

[0006] When an electric vehicle displays DTE based on the consumed amount of the battery and the remaining amount of the battery through running, the battery consumed amount and the driving condition according to the use of electronic units (eg, air conditioner, heater, black box, etc.) Changes, since the displayed DTE and the distance that the electric vehicle can actually travel are different from each other, the battery may be discharged at an unexpected time, therefore, the vehicle may stop unexpectedly
