Collision Detection & Avoidance
Caterpillar Integrated Object Detection System
50 - 60% of accidents reported by mine sites are due to poor
visibility at low speeds (data from various companies and MSHA).
An effective object detection is expected to eliminate a significant
number of these incidents.
8/12/2019 earth moving machine
14/29
The system consists of:
An interactive display in the cab
Medium Range Radar front & rear
(~ 30 metre range)
Short Range Radar front, rear & sides
(~ 7 metre range)
Cameras on all 4 sides of the machine
A vision only system will also be
available, upgradeable to full object
detection system
Expected availability - Sept 09

Collision Detection & Avoidance
Visual alert if object enters caution alarm zone (5 20 metres)
Audible alert if object remains inside 5 metre critical alarm zone in
direction of machines intended path if the operator engages gear and
hasnt acknowledged alarm to full screen view.
