OnGuardMAX Autonomous Emergency Braking System

ZF's most advanced active safety system for commercial vehicles is designed to assist drivers in recognizing and responding to dangerous driving scenarios that could lead to a rear-end collision with a moving or stationary object ahead.
OnGuardMAX enhanced capabilities and features are designed to provide:
  • Road Safety: helps to protect drivers, the road-traveling public and vulnerable road users such as bicyclists, motorcyclists and pedestrians
  • Driver Support: helps to manage highly complex driving situations and improves driver effectiveness across all levels of experience
  • Premium Performance: advanced object detection and classification allows for outstanding reliability and premium performance


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.​


Driver Training Video
  • OnGuardACTIVE is a driver assistance system and is not intended to replace driver control of the vehicle at any time.
  • Driver should take into account the road conditions, and any other factors they are encountering, as they choose to react to any alerts they receive from the OnGuardACTIVE system.
