OnGuard­™ Collision Mitigation System

WABCO introduced the original Collision Mitigation System, OnGuard™, to the commercial vehicle industry in 2008. OnGuard assists truck drivers in recognizing and responding to dangerous driving scenarios that could lead to a rear-end collision. The system provides Forward Collision Warning (FCW), Active Braking, and Adaptive Cruise Control (ACC), and is always on and works when the driver needs it most.




Advanced Emergency Braking System
OnGuardACTIVE™  is an advanced driver assistance system that helps drivers mitigate or avoid rear end collisions. The system detects moving, stopped and stationary objects and provides visual, audible and haptic warnings. If necessary OnGuardACTIVE™  will apply the brakes to avoid or mitigate a forward collision

OnGuardACTIVE™  also has adaptive cruise control. While in cruise, the system detects time to collision of the moving vehicle in front. The system then remains a safe (3.6 seconds) following distance behind the followed vehicle and automatically will adjust its selected speed to remain that same distance behind.

Detects vehicles up to 650 feet ahead

Reliable anytime, including inclement weather

77GHz dual-band radar enables fast data processing for accurate object detection

Retrofit Kits

There are several OnGuardACTIVE retrofit kits available for Freightliner P3 Cascadia vehicles. These kits enable fleets to install the advanced active safety technology on vehicles that were not equipped from the OEM.​​

A clear verification of system requirements is required before a vehicle can be retrofitted with OnGuardACTIVE. Customers can determine if their vehicle is compatible using the OnGuardACTIVE Vehicle Qualification survey.​
