Vehicle collision avoidance system

Abstract

A collision avoidance system for a machine is disclosed including an obstacle detection system configured to detect an obstacle. The collision avoidance system also includes a display configured to provide information to an operator. The collision avoidance system further includes a controller in communication with the obstacle detection system and the display. The controller is configured to control the display to indicate an obstacle detection based on information received from the obstacle detection system and determine a ground speed of the machine. The controller is also configured to determine a distance since the ground speed of the machine was last at a threshold speed and suppress the indication of the obstacle detection based on the distance since the ground speed of the machine was last at the threshold speed.
