Vehicle collision avoidance system
First Claim
1. A collision avoidance system for a machine, comprising:
- a first obstacle detection system configured to detect a first obstacle and generate a corresponding first signal;
an operator interface including a display configured to communicate visual information to an operator;
an interface module configured to detect a status of the machine and generate a corresponding second signal; and
a controller in communication with the first obstacle detection system, the operator interface, and the interface module, and configured to;
control the display to indicate an obstacle detection to the operator, based on the first and second signals; and
control the display to provide an obstacle warning to the operator, based on the first and second signals,determine a ground speed of the machine;
determine a distance since the ground speed of the machine was last zero;
control at least a portion of the display to suppress the indication of the obstacle detection based on the distance since the ground speed of the machine was last zero being more than a threshold distance; and
the ground speed of the machine being above a threshold speed.

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. In addition, the collision avoidance system has an interface module configured to detect a status of the machine and generate a corresponding second signal. The collision avoidance system also has a controller. The controller is in communication with the first obstacle detection system, the operator interface, and the interface module. The controller is configured to control the display to indicate a dangerous obstacle detection to the operator, based on the first and second signals. Additionally, the controller is configured to control the display to provide a dangerous obstacle warning to the operator, based on the first and second signals.
