Hi Umair,

no. The lead vehicle's acceleration does not influence the perception thresholds, but it is used to compute the reacting vehicle's acceleration in the driving modes "approaching (BremxBX)" and "Emergency braking (BremsAX)".

Hi Peter,

Thanks for your answer. If the lead vehicle's speed is not a constant then what is meant by "actual speed level"? Is it an interval of speed, e.g. actual speed level of lead vehicle: 50 to 60 meters per second?

@Peter Vortisch, I want to point out that the example trajectory in Figure 2-1 (in the reference with my question above) is usually only possible when lead vehicle is moving at uniform speed. If both vehicles are accelerating (or deccelerating) the hysteresis loop is not observed in dV-dx diagram
