Abstract

A method for controlling a cruise control system on a vehicle includes identifying a vehicle location and identifying a number of respective cruise control overrides by a driver at the vehicle location. If the number of cruise control overrides by the driver is at least a threshold number of overrides, identifying respective actions by the driver after the cruise control overrides, and creating a profile of the driver behavior associated with the vehicle location based on the respective actions by the driver within a range around the vehicle location after the driver overrode the cruise control.
