OnGuard system includes active braking

Meritor WABCO Vehicle Control Systems has introduced OnGuard, a forward-looking, radar-based adaptive cruise control system with active braking for commercial vehicles in North America. New to the North American industry, the system improves vehicle safety by automatically using the vehicle foundation brakes to decelerate the vehicle when a pre-set vehicle following distance is compromised.

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 OnGuard, if the pre-determined “safe” distance is compromised, the system 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, says Jon Morrison, president and general manager, Meritor WABCO Vehicle Control Systems.

OnGuard fully integrates with the joint venture's anti-lock braking (ABS) and stability control systems. Morrison said this allows the user to build a pyramid of safety for the vehicle with stability control and collision safety system via a single brake ABS electronic control unit (ECU) versus having other “add-on” systems.
