  • Patent number: 10156453
    Abstract: An electric vehicle route guide system includes: a location sensor that measures a current location of an electric vehicle; a roadmap storage having link information and node information for providing a running route; a route calculator that searches for a route having a smallest total value of a compensation link cost that is generated by adding a time link cost in consideration of a running time to an energy-based link cost on each link basis from a departure point to a destination as an optimal energy route; a display that displays information for route guide of the optimal energy route; and a controller that controls operations of the location sensor, the roadmap storage, the route calculator, and the display for the search and route guide through a navigation program.
