  • Patent number: 8423280
    Abstract: A method for collision avoidance for a machine is disclosed. The method includes detecting an obstacle with an obstacle detection system and generating a corresponding signal. The obstacle detection system includes an operator input device. The method also includes providing an obstacle detection warning in response to the signal. The method further includes determining with a controller whether the operator input device has been activated in response to the obstacle detection warning.
    Type: Grant

  • Patent number: 8280621
    Abstract: A collision avoidance system for a machine is disclosed. The collision avoidance system has a first obstacle detection system. The first obstacle detection system is configured to detect a first obstacle and generate a corresponding first signal. Additionally, the collision avoidance system has an operator interface. The operator interface has a display configured to communicate visual information to an operator. The operator interface also has an input device configured to receive selections from the operator and generate a corresponding second signal. In addition, the collision avoidance system has a controller. The controller is in communication with the first obstacle detection system and the operator interface. The controller is configured to control the display to provide a first dangerous obstacle warning to the operator, based on the first signal.

  • Publication number: 20120245798
    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.
