Active Brake Assist 5 is the next step on from the tried-and-tested emergency braking system Active Brake Assist 4 from Mercedes-Benz. This generation combines radar and camera. The new sensor fusion has dramatically improved response to moving pedestrians at speeds of up to 50 kilometres per hour. Active Brake Assist 5 is now capable of applying maximum full-stop braking in response to pedestrians crossing its path, approaching from the front or moving ahead.
Avoiding rear-end collisions.
Active Brake Assist 5 can detect vehicles ahead and stationary obstacles in the vehicle's own lane – at vehicle speeds up to 90 km/h. If the system detects a dangerous situation, a three-stage reaction is immediately triggered:
- Visual signals and a loud beep
warn the driver
- Partial braking with approx. 50% braking power
is performed in order to reduce the speed (if the driver has not reacted beforehand)
- Maximum full-stop braking
is initiated in order to bring the vehicle to a standstill (if the driver has still not reacted)
If the system detects crossing pedestrians or people standing on the carriageway, the reaction chain is shortened even further. The driver is warned both visually and acoustically, but partial braking is simultaneously initiated autonomously. Because when people's lives are at stake, there is no time for hesitation.
Pedestrian detection can occur up to a vehicle speed of 50 km/h: if pedestrians cross the truck's lane, approach it or walk in its lane.
