Title: Method and system for adjusting headway in an adaptive speed control system based on road surface coefficient of friction

Abstract: In an adaptive speed control system for a vehicle, a method and system for automatically adjusting a selected following interval for the vehicle based on driving conditions is provided. The method includes determining a driving surface coefficient of friction based on a driven wheel speed of the vehicle, and adjusting the selected following interval for the vehicle based on the driving surface coefficient of friction. The system includes a receiver capable of receiving a signal indicative of a driven wheel speed of the vehicle, and a controller capable of determining a driving surface coefficient of friction based on the driven wheel speed, and capable of adjusting the selected following interval for the vehicle based on the driving surface coefficient of friction.
