Abstract

Various embodiments relate to determining a route for efficient energy consumption. Data defining one or more routes and one or more consumption influencing parameters which influence a consumption of an energy source of the vehicle along the one or more routes may be received at a vehicle computer. Based on the route data and the consumption influencing parameters, at least one route which minimizes the consumption of the energy source for the vehicle may be determined. For the at least one route, one or more braking strategies may be determined for implementation by a vehicle operator in the vehicle in accordance with reducing the consumption of the vehicle energy source. The one or more braking strategies may be output in the vehicle.

First claim

What is claimed is:

1. A system comprising:
a processor configured to:
determine a route which minimizes vehicle energy consumption, based on received route data and a received consumption influencing parameter that influences vehicle energy consumption;
for the determined route, determine a vehicle energy consumption reduction braking strategy that relies on different energy preservation strategies correlating to different route portions; and
output the braking strategy in the vehicle, changing output energy preservation strategies as correlated route portions are reached.

2. The system of claim 1 wherein the braking strategies include at least one of regenerative braking, conventional braking, engine braking, coasting, and shutting down the engine of the vehicle when in a stationary state.

3. The system of claim 1 wherein the processor is further configured to:
segment the a possible route into a plurality of segments;
determine a consumption value for each of the plurality of segments of the possible route; and
determine whether the possible route minimizes the consumption of the energy source based on the consumption value for each of the plurality of segments.

4. The system of claim 3 wherein the consumption values for each of the plurality of segments are summed determine whether the possible route minimizes the consumption of the energy source.

5. The system of claim 1 wherein the consumption influencing parameter includes a driving style of a vehicle operator.

6. The system of claim 5 wherein the processor is configured to:
identify the vehicle operator based on a vehicle operator identifier; and
obtain the driving style of the vehicle operator once the vehicle operator is identified.

7. The system of claim 5 wherein the driving style includes a braking behavior of the vehicle operator, the processor being further configured to determine the one or more braking strategies in accordance with the braking behavior of the vehicle operator.

8. The system of claim 1 wherein the consumption influencing parameter includes a plurality of parameters including vehicle parameters, weather- related parameters, traffic parameters, and route-dependent parameters.

9. A computer-implemented method for optimizing energy consumption in a vehicle along a route, the method comprising:
receiving at a vehicle computer data defining one or more routes;
receiving at the vehicle computer one or more consumption influencing parameters which influence a consumption of an energy source of the vehicle along the one or more routes;
based on the route data and the consumption influencing parameters, determining at the vehicle computer at least one route which minimizes the consumption of the energy source for the vehicle;
for the at least one route, determining at the vehicle a braking strategy for implementation by a vehicle operator, having different energy preservation strategies correlated to different route portions; and
outputting the braking strategy in the vehicle, including outputting the different energy preservation strategies as the correlated route portions are reached.

10. The method of claim 9 wherein the outputting includes outputting through at least one of a haptic output, acoustic output, or optical output.

11. The method of claim 9 wherein determining the route which minimizes the consumption of the energy source further includes
segmenting the route into a plurality of segments;
determining a consumption value for each of the plurality of segments of the route; and
determining whether the route minimizes the consumption of the energy source based on the consumption value for each of the plurality of segments.

12. The method of claim 9 wherein the consumption influencing parameters includes a driving style of the vehicle operator.

13. The method of claim 12 further comprising recording driving data for the vehicle operator for determining the driving style.

14. The method of claim 13 further comprising:
receiving driving data that deviates from the recorded driving data; and
updating the driving style of the vehicle operator based on the deviating driving data.

15. The method of claim 12 further comprising storing at the vehicle computer the driving style for at least two vehicle operators.

16. The method of claim 12 wherein the driving style include a braking behavior of the vehicle operator, the method further comprising determining the one or more braking strategies in accordance with the braking behavior of the vehicle operator.
