Detection process for impending rear-end impact has delay factor applied to second vehicle, such as relative delay or inherent delay of second vehicle

摘要

The detection process includes a rear-facing spacing or speed sensor (3) on the first vehicle (1). This detects at least the spacing (d12) and relative speed (Vrel) of the following second vehicle (2) and reports these is an impact is likely or at least possible. A delay factor is applied to the data relating to the second vehicle, such as its relative delay or inherent delay.
