Minimum energy route for a motor vehicle
First Claim
Patent Images
1. A method of operating a navigation system including a computer system in communication with at least one database, the computer system being configured to perform the steps of:
- receiving a minimum energy route request from an electronic control unit of a motor vehicle, the request including a starting location and an ending location;
retrieving information from an energy map stored in the at least one database, the energy map including energy information related to a first power source and a second power source that is different from the first power source;
calculating a minimum energy route between the starting location and the ending location that minimizes a total energy consumed by the combination of the first power source and the second power source;
sending information related to the minimum energy route to the electronic control unit;
wherein the minimum energy route includes a plurality of road segments; and
wherein the retrieved information from the energy map includes energy information for the first power source and the second power source for the plurality of road segments.

6. A method of operating a motor vehicle, the motor vehicle including a navigation system configured to perform the steps of:
-
receiving a starting location and an ending location; retrieving information from an energy map stored in a database in communication with the navigation system, the energy map including energy information related to a plurality of different power sources; calculating a minimum energy route between the starting location and the ending location that minimizes the energy consumed by at least one of the power sources of the plurality of different power sources; providing directions to the user for guiding the vehicle to the ending location along the minimum energy route; wherein the minimum energy route includes a plurality of road segments; wherein the retrieved information from the energy map includes energy information for each of the first power source and the second power source for the plurality of road segments; and wherein the minimum energy route is calculated based on the energy information for the first power source and the second power source for each road segment of the plurality of road segments from the starting location to the ending location. - View Dependent Claims (7, 8, 9, 13, 14, 15, 16, 17)
