RADAR INITIATED FOUNDATION BRAKING ONLY FOR AUTONOMOUS EMERGENCY BRAKING SITUATIONS
First Claim
1. A controller unit that facilitates prioritizing collision mitigation over at least one other type of vehicle control protocol, comprising:
- a non-transitory computer-readable medium that stores computer-readable instructions for prioritizing collision mitigation when a collision is determined to be imminent; and
a processor that executes the instructions, the instructions comprising;
monitoring a distance between a host vehicle and a forward vehicle;
maintaining a set following time behind the forward vehicle by employing at least one of a throttle control component and an engine retarder component while prohibiting foundation braking when the forward vehicle is beyond a predetermined collision mitigation threshold;
detecting an automatic emergency braking event wherein the forward vehicle breaches the predetermined collision mitigation threshold; and
permitting foundation braking upon detection of the automatic braking event.

Abstract
When providing adaptive cruise control (ACC) in addition to collision mitigation (CM) for a large vehicle, foundation braking is prohibited for maintaining a set following time behind a forward vehicle in order to mitigate unnecessary brake activations. When collision mitigation is activated, the collision mitigation system is given priority over other vehicle control systems with regard to the foundation brakes, in order to avoid a collision. A lateral acceleration module monitors lateral acceleration of the host vehicle during collision mitigation foundation brake application, and if lateral acceleration exceeds a predetermined threshold, foundation brakes are prohibited in order to prevent vehicle rollover.
