1. A method of automatically transitioning a cruise control speed from a current speed zone to a next speed zone, the method comprising the steps of:

  • determining a location at which the speed zone limit changes from the current speed limit to the next speed limit forward of a driven vehicle;

    determining a speed profile for changing the vehicle speed from the current speed limit to the next speed limit, the speed profile including non-linear changes in the vehicle speed between the current speed zone and the next speed zone for eliminating abrupt changes in the vehicle speed;

    determining a relative location for initiating the non-linear changes in the speed of the vehicle; and

    actuating the non-linear changes in the speed of the vehicle at the relative location for gradually changing the speed to the next speed limit.
