1. A driver coaching system, comprising:
- an input device configured to generate a signal indicative of a road sign displaying a speed limit; and
an advisory device configured todisplay an output indicative of a fuel efficiency rating based on a vehicle speed and an optimum fuel efficient speed, andrefrain from decreasing the rating when the speed limit prohibits the optimum fuel efficient speed and the vehicle speed is in compliance with the speed limit, wherein one or more ofthe advisory device refrains from decreasing the fuel efficiency rating responsive to the advisory device determining that the signal indicates the road sign displays a minimum speed limit greater than the optimum fuel efficient speed and the vehicle speed is at least the minimum speed limit, orthe advisory device refrains from decreasing the fuel efficiency rating responsive to the advisory device determining that the signal indicates the road sign displays a maximum speed limit less than the optimum fuel efficient speed and the vehicle speed is up to the maximum speed limit.

Abstract
A driver coaching system may have an input device generating an input signal indicative of a road condition. The system may also include an advisory device determining an output conveyed to a driver and indicative of a fuel efficiency rating based on an actual vehicle speed and an optimum fuel efficient speed. The advisory device may not decrease the fuel efficiency rating when the road condition does not warrant the optimum fuel efficient speed.
