Abstract

A system for providing a recommended route for a vehicle, from a current location to an intermediate destination, to a final destination. The system includes an electronic control unit (ECU) configured to determine a vehicle range exceeding a distance between the current location of the vehicle and the intermediate destination. The ECU is configured to determine a baseline route having a first section and a second section. The ECU is configured to determine a first energy source of the first section and a second energy source of the second section. The ECU is configured to determine a first cost associated with incorporating the first energy source and a second cost associated with incorporating the second energy source. The ECU is also configured to determine the recommended route based on the first cost and the second cost. The system also includes an output unit configured to output the recommended route.

First claim

a vehicle energy sensor configured to detect vehicle energy data and vehicle energy efficiency data;
an electronic control unit (ECU) configured to:
determine the intermediate destination by predicting the intermediate destination based on the vehicle location history data or by receiving the intermediate destination from an input unit, the intermediate destination being a stop between the current location and the final destination,
determine a vehicle range based on the vehicle energy data and the vehicle energy efficiency data, the vehicle range exceeding a distance between the current location of the vehicle and the intermediate destination,
determine a baseline route having a first section between the current location and the intermediate destination, and a second section between the intermediate destination and the final destination,
determine a first energy source from the plurality of energy sources within a predetermined range along the first section and a second energy source from the plurality of energy sources within the predetermined range along the second section based on the energy source location data and energy source cost data, the first energy source and the second energy source being within the vehicle range,
