ACC and AM braking range variable based on internal and external factors
First Claim
1. A method of reducing an allowable braking reaction distance (BRD) for a host vehicle as a function of a detected trigger event, comprising:
- setting an initial BRD for the host vehicle;
monitoring one or more trigger conditions;
detecting a trigger event;
reducing the BRD by a predefined amount that corresponds to the type of trigger event that is detected;
prior to detection of the trigger event, restricting foundation braking while permitting dethrottling and engine retardation; and
permitting foundation braking after detection of the trigger event.

Abstract
When employing an adaptive cruise-with-braking (ACB) system to control host vehicle braking reaction distance, a plurality of trigger conditions (e.g., environmental parameters) are monitored. If one or more of the monitored parameters exceeds a predefined threshold, a trigger event is detected, and at least one of a braking reaction distance (BRD) and a following distance limit shape (FDLS) are adjusted. The BRD and FDLS adjustments may be predefined according to the type and/or magnitude of the trigger event. Trigger events may be weighted or prioritized such that higher priority trigger event types correspond to larger BRD reductions, etc. Monitored trigger conditions may include adverse weather, dangerous road terrain or topography, high traffic density, erratic forward vehicle behavior, and the like.
