In the past five years, Meritor WABCO 's brake anti-collision warning system (CMS) has been applied to commercial vehicles. The system uses a three-beam sensing radar device to detect the vehicle in front, with a sensing range of 150 meters (492 feet).
Alan Korn, head of automotive control systems at Meritor WABCO, said that their biggest problem now is that the system can only detect objects in front of it, and it cannot distinguish whether the detected front object is a Coke can or a big truck.
The next-generation OnGuard system has 34 independent beams that can scan all objects within 18 degrees of the front, within 200 meters of each other, and within 60 meters of the side within 56 degrees.
Korn explained: "With the availability of next-generation systems, the radar sensing system is more robust and can sense whether objects are a threat to the vehicle from a multi-directional perspective and decide whether to force the brakes or issue a warning."
When the system determines that a rear-end collision is about to occur, the system will issue an alarm and there will be a warning light on the high-resolution LCD screen on the dashboard. The color changes from green to yellow or even red. The new generation of systems will also automatically perform fine-tuning, with adaptive adjustments of ±3° in the horizontal and vertical planes of the radar scan, whereas previous generation systems required manual corrections.
Because the next-generation system will have a wider scan-sensing coverage, the system can also identify vehicles in adjacent lanes.
The system will not wait for the driver to react because the driver does not make a proper avoidance response when he senses a threat vehicle on the adjacent lane. At this time, the system brakes itself based on the detected situation.
Jon Morrison, General Manager of Meritor WABCO, said that since 2004, the company has been working to improve the functionality of the OnGuard system. At that time, the technology had not yet been introduced to the market but it had undergone many improvements. Since that year, more than 25,000 commercial vehicles have carried the system and traveled a total of more than 3 billion miles.
The next-generation CMS system will be available after October 1, 2012. Company officials hope that before 2014, CMS will be able to increase the function of detecting stationary objects.
At the same time, the company also introduced the LDW fatigue driving detection system and the ESCsmart electronic stability control system. Meritor WABCO's more than 150,000 stability control systems have been used on long-distance transport trucks, fire engines, and buses in North America.
Morrison said, "Meritor WABCO will overcome various technical challenges in the process of cooperation between original equipment manufacturers to achieve further technological goals."
