9.4.5. Interference-force estimation
Interference-force estimation as implemented in the ACC Stop & Go system is based on the counterpart function in Dynamic Cruise Control. However, a considerable degree of optimization is necessary, since inaccuracies in the interference-force estimation become much more perceptible in the low range of driving speeds (less than 30 km/h/20mph) than at higher driving speeds. Consequently, the estimation precision is better than that of the Dynamic Cruise Control system and the reaction to changes in interference forces is faster.
