Meritor OnGuard System

Meritor 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.
OnGuard's forward-looking, mono-pulse radar sensor is capable of detecting multiple moving and fixed objects at distances up to 500 feet away. It quickly and reliably coordinates responses from the engine, transmission, and antilock braking systems through communications across the SAE J1939 data network. It provides feedback to the driver through the in-cab dash display, which includes a progressive audible alert.
This sequence of monitoring, warning and intervention is an important part of Meritor WABCO's strategy to reduce false alarms. OnGuard uses a proprietary time-to-collision algorithm, unlike the simple two-second headway alarms used by today's passive braking systems. Driver feedback from field tests covering over 10 million fleet-miles over a two-year period showed significantly better performance, reliability, and driver confidence in OnGuard compared to collision warning systems currently available in North America.
