DRIVER FEEDBACK FOR FUEL EFFICIENCY
First Claim
1. One or more computer-readable memory or storage devices storing instructions that, when executed by a computing device having a processor, perform a method for increasing vehicle fuel efficiency, the method comprising:
- receiving vehicle speed or acceleration data for a location on a route;
deriving a current acceleration value for the location using the received vehicle speed or acceleration data;
determining a preferred acceleration value for the location based on a preferred speed or acceleration profile that is specific to the route; and
providing an indication of a correspondence between the preferred acceleration value for the location and the current acceleration value for the location.

Abstract
Systems, methods, and computer-readable media for providing feedback to a driver are provided herein. Vehicle speed or acceleration data can be received for a location on a route. A current acceleration value for the location is derived using the received vehicle speed or acceleration data. A preferred acceleration value for the location is determined based on a preferred speed or acceleration profile that is specific to the route. An indication of a correspondence between the preferred acceleration value for the location and the current acceleration value for the location is then provided. The indication can be, for example, a graphic comparing the preferred and current acceleration values. Based on the indication, a driver can adjust acceleration to conform to the preferred acceleration value.

12. A computer-implemented method for increasing vehicle fuel efficiency, the method comprising:
-
receiving an observed speed or acceleration profile that is specific to a route; based at least in part on the observed speed or acceleration profile, determining a preferred speed or acceleration profile that is specific to the route, wherein the preferred speed or acceleration profile provides greater fuel efficiency over the route compared to the observed speed or acceleration profile; and storing the preferred speed or acceleration profile for use in a real-time feedback system. - View Dependent Claims (13, 14, 15, 16)

17. A computer-implemented method for increasing vehicle fuel efficiency, the method comprising:
for each of a plurality of locations on a route; receiving speed and location data for a vehicle at the location on the route; determining a current vehicle speed based on the received speed data; if the current vehicle speed is greater than a threshold, determining a preferred vehicle acceleration value for the location based on a preferred speed or acceleration profile for the route; if the current vehicle speed is less than the threshold, determining an alternative preferred vehicle acceleration value; calculating a current vehicle acceleration value for the location using the received speed and location data; and displaying a graphic comparing the current vehicle acceleration value to either the preferred vehicle acceleration value or the alternative preferred vehicle acceleration value. - View Dependent Claims (18, 19, 20)
