Daimler Buses is introducing Active Brake Assist 4 (ABA 4) with pedestrian recognition claimed to be the world's first emergency braking assistance system in a bus to automatically brake for pedestrians.

The new system warns the driver visually and audibly of any potential collision with pedestrians and automatically triggers partial braking.

This gives the driver every opportunity to prevent a collision with a pedestrian: the driver can warn the pedestrian using the horn, initiate maximum full-stop braking or steer to avoid the collision.

The system is based on new generation radar technology. The electronically scanning multi-mode radar comprises long and short range radar systems.

The long range radar registers multi-track vehicles and stationary obstacles at a maximum distance of up to 250m in a direct line in front of the coach single track vehicles such as bicycles at up to 160m and pedestrians at up to 80m. The short range radar has a maximum range of 70m and is even able to recognise pedestrians and vehicles to the sides ahead of the coach.

The fourth generation system is an evolution of a system which already carried out maximum full-stop braking for vehicles ahead and for stationary obstacles.

Since November 2015, emergency braking systems have been mandatory for newly registered heavy duty coaches and trucks in Germany.

ABA 4 will become available in spring 2018 for the recently launched Mercedes-Benz Tourismo. Setra touring coaches will also have the system which is available free of charge to customers selecting the popular autonomous intelligent cruise control option (ART) which provides the necessary radar technology.
