CLICS

Cooperative Localization to Improve Convoy Stability

CLICS optimizes convoy vehicle tracks by combining sensor updates of vehicles in the convoy in a distributed, cooperative localization system.

CLICS is a Phase II SBIR with TARDEC that optimizes convoy vehicle tracks by intelligently combining sensor updates of all vehicles in the convoy in a distributed, cooperative localization system. Currently, follower vehicles in the convoy rely either on GPS breadcrumbs from the lead vehicle, or rely on sensing the location of its predecessor and following its path. However, GPS availability and accuracy oftentimes cause the former solution to fail, and accumulated errors in tracking and control in long convoys can cause the latter solution to fail. In the case of the autonomous convoy application, the problem is that the GPS accuracy can be larger than the amount required to follow a lead vehicle and to stay on the road. Robotic Research’s CLICS system attempts to overcome these problems.
