1. A driver coaching system, comprising:
- an input device configured to generate an input signal indicative of a road condition; and
an advisory device configured toconvey an output indicative of a fuel efficiency rating for a vehicle based on a vehicle speed and an optimum fuel efficient speed, andrefrain from decreasing the fuel efficiency rating when the vehicle is within a minimum stopping distance from the road condition.

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.

14. A system comprising:
-
an input device configured to generate an input signal indicative of a road condition; a stopping distance database including a lookup table of a plurality of reference minimum stopping distances for a vehicle and an associated plurality of reference vehicle speeds; a global position satellite unit configured to determine a vehicle distance from the road condition; a controller configured to determine an instantaneous minimum stopping distance in response to comparing a vehicle speed to the plurality of associated reference vehicle speeds, and generate an override output signal in response to determining that the vehicle distance is less than the minimum stopping distance; and an advisory device configured to convey an output indicative of a fuel efficiency rating for the vehicle based on the vehicle speed and an optimum fuel efficient speed, and refrain from decreasing the fuel efficiency rating when the vehicle is within the minimum stopping distance from the road condition as indicated by the override output signal.
