MODIFYING ADAPTIVE CRUISE CONTROL TO MITIGATE REAR-END COLLISIONS
First Claim
1. A system for controlling a host vehicle, the system comprising:
- at least one controller configured to;
adjust a speed of the host vehicle to maintain at least a predetermined followingdistance between the host vehicle and a front vehicle traveling ahead of the host vehicle,receive data from at least one rearward-facing environment sensor mounted on the host vehicle,determine, based on the data from the at least one rearward-facing environment sensor, whether a rear vehicle is traveling behind the host vehicle,detect, based on the data from the at least one rearward-facing environment sensor, a critical rear-collision risk,reduce the predetermined following distance to a second minimum following distance when the critical rear-collision condition is detected, andautomatically increase the speed of the host vehicle to maintain the second minimum following distance between the host vehicle and the vehicle tranveling ahead of the host vehicle when the critical rear-collision condition is detected.

Abstract
Methods and systems for controlling a host vehicle to mitigate rear-end collisions. One method includes automatically maintaining the host vehicle at least a predetermined following distance from a front vehicle traveling ahead of the host vehicle. The method also includes detecting a rear vehicle traveling behind the host vehicle and determining when the rear vehicle poses a rear-end collision risk with the host vehicle. In addition, the method includes automatically, by a controller, increasing a speed of the host vehicle when the rear vehicle poses a rear-end collision risk with the host vehicle, and automatically reducing the predetermined following distance to decrease a distance between the host vehicle and the front vehicle and increase a distance between the host vehicle and the rear vehicle when the rear vehicle poses a rear-end collision risk with the host vehicle.
