Abstract:
A system and method for mitigating collisions for an articulated work vehicle is disclosed. The system includes a controller configured to determine a safe-zone around the articulated work vehicle based on signals corresponding to sensed objects around the articulated work vehicle. The controller is further configured to determine a position and velocity of one or more peripheral points on the articulated work vehicle based on signals from a set of sensor systems operatively coupled to the articulated work vehicle. The controller is further configured to receive a driver control input. The controller is further configured to apply a limit to the driver control input when a peripheral point on the articulated work vehicle is expected to be within a predetermined distance to a nearest edge of the safe-zone.
