Route guidance device, method, and program
First Claim
1. A route guidance device for a vehicle that is provided with a drive motor and an engine as drive sources, comprising:
- a controller that;
acquires a departure point and a destination for the vehicle;
determines candidate links;
estimates a driving force of the vehicle that is required for driving each candidate link;
specifies from among the candidate links one or more motor drive recommended links for which the estimated driving force of the vehicle is not greater than a specified threshold value, the specified threshold value being a driving force value above which the engine of the vehicle must be operated in addition to the drive motor, the motor drive recommend links being links for which the vehicle can drive using only the drive motor as the drive source;
specifies a route that includes only motor drive recommended links and by which the vehicle can drive from the departure point to the destination using only the drive motor as the drive source; and
outputs the specified route on a display.

Abstract
Route guidance devices, methods, and programs provide guidance for a vehicle that is provided with a drive motor and an engine as drive sources. The devices, methods, and programs acquire a departure point and a destination for the vehicle and specify one or more motor drive recommended links for which driving with the drive motor as the drive source is recommended. The devices, methods, and programs specify a route that includes only motor drive recommended links and by which the vehicle can drive from the departure point to the destination using only the drive motor as the drive source and output the specified route on a display.

14. A non-transitory computer-readable storage medium storing a computer executable program usable to provide route guidance for a vehicle that is provided with a drive motor and an engine as drive sources, the program comprising:
-
instructions for acquiring a departure point and a destination for the vehicle;
instructions for determining candidate links;instructions for estimating a driving force of the vehicle that is required for driving each candidate link; instructions for specifying from among the candidate links one or more motor drive recommended links for which the estimated driving force of the vehicle is not greater than a specified threshold value, the specified threshold value being a driving force value above which the engine of the vehicle must be operated in addition to the drive motor, the motor drive recommend links being links for which the vehicle can drive using only the drive motor as the drive source; instructions for specifying a route that includes only motor drive recommended links and by which the vehicle can drive from the departure point to the destination using only the drive motor as the drive source; and instructions for outputting the specified route on a display.
