Abstract

A system and method of tracking energy usage in a vehicle. The method, in one implementation, involves building an energy usage prediction model, obtaining a planned route for a vehicle that contains one or more planned route segments, applying the energy usage prediction model to each planned route segment of the one or more planned route segments of the planned route to obtain an energy usage plan, receiving onboard data from the vehicle, constructing an actual route based on the onboard data, and performing a match analysis between the planned route and the actual route based on the onboard data.

First claim

What is claimed is:

1. A method of tracking energy usage in a vehicle, the method comprising:
building an energy usage prediction model specific to a vehicle make and/or a vehicle model of the vehicle;
obtaining a planned route for the vehicle, the planned route containing a plurality of planned route segments;
applying the energy usage prediction model to each of the planned route segments of the planned route to obtain a respective predicted energy usage for each of the planned route segments to collectively define an energy usage plan;
receiving onboard data from the vehicle;
constructing an actual route of the vehicle based on the onboard data, the actual route containing a plurality of actual route segments;
performing a match analysis between multiple of the planned route segments of the planned route and multiple of the actual route segments of the actual route, based on the onboard data, a real-time vehicle location, and a search window aligned with the real-time vehicle location and having a preset size with upper and lower bounds, to identify a deviation between the planned route and the actual route;
generating a revised planned route for the vehicle responsive to the deviation in the match analysis, the revised planned route including the planned route segments with modified route segment attributes, with at least one of the planned route segments removed, and/or with at least one new planned route segment added; and
applying the energy usage prediction model to one or more of the planned route segments of the revised planned route to obtain predicted energy usage information for the one or more of the planned route segments of the revised planned route to collectively define a revised energy usage plan for the vehicle.

2. The method of claim 1 , further comprising obtaining route information including a route start location and a route end location from the vehicle, wherein the route information is used to obtain the planned route for the vehicle.

3. The method of claim 1 , wherein the energy usage plan includes a plurality of usage plan route segments, each of the usage plan route segments being associated with a respective one of the planned route segments and the predicted energy usage information of the respective planned route segment.

4. The method of claim 1 , wherein the match analysis includes matching a planned route segment of the plurality of planned route segments of the planned route to an actual route segment of the plurality of actual route segments of the actual route based, at least partly, on a geographical proximity between the planned route and the actual route.

5. The method of claim 1 , wherein defining the revised energy usage plan further comprises re-calibrating the energy usage plan based on route matching feedback information, the route matching feedback information including energy usage information obtained from the vehicle.

6. The method of claim 5 , wherein the route matching feedback information includes at least some of the onboard data received from the vehicle, wherein the at least some of the onboard data is associated with a geographical point along the actual route segment that is matched to the planned route segment, and the at least some of the onboard data includes the energy usage information.

7. The method of claim 1 , wherein the match analysis includes:
tentatively matching a first actual route segment of the actual route segments of the actual route to a first planned route segment of the planned route segments of the planned route to obtain a tentative match; and
confirming the tentative match to obtain a confirmed match upon tentatively matching a second actual route segment of the actual route segments to a second planned route segment of the planned route segments, the second actual route segment being further along the actual route than the first actual route segment, and the second planned route segment being further along the planned route than the first planned route segment.

8. The method of claim 7 , wherein identifying the deviation includes:
determining if a match displacement between the first actual route segment and the second actual route segment is greater than a predetermined detour displacement threshold; and
identifying the tentative match as a detour match responsive to a determination that the match displacement between the first actual route segment and the second actual route segment is greater than the predetermined detour displacement threshold.

9. The method of claim 1 , wherein the method is carried out by one or more servers located at a vehicle backend services facility, the one or more servers each including a processor, and wherein the one or more servers include computer instructions that, when executed, cause the processors to carry out the method steps.

10. A method of tracking energy usage in a vehicle, the method comprising:
receiving route information from the vehicle, the route information including a route start location and a route end location;
obtaining a planned route for the vehicle based on the route information, wherein the planned route includes a plurality of planned route segments;
generating a respective predicted energy usage for each of the plurality of planned route segments to collectively define an energy usage plan, the predicted energy usages of the planned route segments being based on onboard data received from the vehicle and off-board data obtained from a database;
receiving onboard data from the vehicle, the onboard data including energy usage data of the vehicle;
constructing an actual route of the vehicle based on the onboard data, wherein the actual route includes a plurality of actual route segments;
performing a match analysis by matching one or more of the actual route segments to one or more of the planned route segments to obtain a matched route segment pair, the matched route segment pair including a respective one of the actual route segments and a respective one of the planned route segments matched to the respective one of actual route segments, and wherein the matching is based, at least partly, on a real-time vehicle location, a search window aligned with the real-time vehicle location and having a preset size with upper and lower bounds, and a geographical proximity between the one or more actual route segments and the one or more planned route segments; and
updating the predicted energy usage information for a subset of the planned route segments, wherein the subset of planned route segments includes one or more of the plurality of planned route segments that are further along the planned route than the planned route segment of the matched route segment pair.

11. The method of claim 10 , wherein the onboard data received from the vehicle includes: a state of charge (SoC) value of a battery pack of the vehicle;
and heating, ventilation, and air conditioning (HVAC) information of the vehicle.

12. The method of claim 10 , wherein the updating step is based on at least part of the energy usage data received from the vehicle.

13. The method of claim 12 , wherein the subset of planned route segments that are updated includes all of the plurality of planned route segments that are further along the planned route than the planned route segment of the matched route segment pair.

14. The method of claim 13 , wherein the updating step includes generating predicted energy usage information for each planned route segment in the subset of planned route segments.

15. The method of claim 14 , further comprising:
inputting the matched route segment pair along with corresponding ener
