New Active Braking System Launched

Meritor WABCO Vehicle Control Systems has introduced OnGuard, a new technology designed to further improve commercial vehicle safety.
OnGuard is currently installed on nearly 200 vehicles and is targeted for third quarter 2008 availability as a factory-installed option at several OEM brands.
OnGuard is a forward-looking, radar-based adaptive cruise control system with active braking for commercial vehicles in North America.
New to the North American industry, active braking improves vehicle safety by automatically using the vehicle foundation brakes to alert the driver and decelerate the vehicle when a pre-set vehicle following distance is compromised.
“As part of our ongoing efforts to improve vehicle safety for highways, drivers and fleets, OnGuard was designed to equip drivers with automated features that help ensure safe following distances and provide active braking as needed,” said Jon Morrison, president and general manager, Meritor WABCO Vehicle Control Systems.
“The driver is still the most important element in maintaining vehicle safety however, the system can provide the additional split-second deceleration needed to maintain control of the vehicle in an emergency situation.”
Automatic foundation brake intervention distinguishes OnGuard from existing passive collision warning systems, which can only alert the driver to a potentially dangerous situation through alarm and engine braking.
With this new product on the truck, if the pre-determined “safe” distance is compromised, OnGuard will provide visual and audible warning to the driver, vehicle deceleration through engine control, retarder control and most importantly, noticeable foundation braking. Foundation brake deceleration can be as great as one-third of a full brake application for the vehicle but within safe limits for the driver to take control.
Further advantage provided by OnGuard is that it fully integrates with the joint venture’s anti-lock braking and stability control systems. According to the U.S. National Highway Transportation Safety Administration, rear-end collisions account for over 20 percent of all heavy- truck crashes.
The truck is the striking vehicle in 60 percent of those accidents.
Inattention or poor decisions (e.g. driving too fast for the conditions or following too closely) are the primary factor in 66 percent of the collisions where fault is assigned to the truck driver.
