- ABA 4 will be available in Mercedes-Benz and Setra touring coaches from the spring of 2018
- ABA 4 warns the driver and triggers braking
- Multi-mode radar systems with a range of up to 250 m
- Active Brake Assist: more capable with each generation
Daimler Buses and its product brands Mercedes-Benz and Setra have traditionally played a pioneering role when it comes to safety and assistance systems. Now Daimler Buses is opening up another new chapter with the new Active Brake Assist 4 (ABA 4) with pedestrian detection: this is the world's first emergency braking assistance system in a touring coach to brake automatically for pedestrians. This marks another whole new level of performance for the system.
ABA 4 warns the driver and triggers braking
Avoiding accidents and protecting more vulnerable road users are central facets of safety development at Daimler Buses. The new Active Brake Assist 4 with pedestrian detection very much reflects this, warning the driver visually and audibly of any potential collision with pedestrians and at the same time automatically triggering 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.
Multi-mode radar systems with a range of up to 250 m
In technical terms, Active Brake Assist 4 with pedestrian detection is based on new-generation radar technology that also features in the latest Mercedes-Benz cars and trucks. 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 250 m in a direct line in front of the touring coach, single-track vehicles such as bicycles at up to 160 m and pedestrians at up to 80 m. The short-range radar has a maximum range of 70 m and is even able to detect pedestrians and vehicles to the sides ahead of the touring coach.
Active Brake Assist: more capable with each generation
The new Active Brake Assist 4 with pedestrian detection is the logical evolution of the existing, tried-and-tested Active Brake Assist 3, which already carries out maximum full-stop braking for vehicles ahead and for stationary obstacles. Daimler Buses caused a sensation with its previous emergency braking systems, from the first Active Brake Assist back in 2008 to Active Brake Assist 3, introduced in 2014. During that time, the system's capabilities have been continually enhanced.
Safety experts understand that Active Brake Assist can save lives. Which is why the legislators reacted to the developments at Daimler Buses: since November 2015, emergency braking systems have been mandatory for newly registered heavy-duty touring coaches and trucks. Even the standard AEBS version from Daimler Buses can do more than the legislators require. The new Active Brake Assist 4 with pedestrian detection once again sets new standards with even better performance.
Market launch to begin in spring of 2018
ABA 4 will become available in the spring of 2018 for the recently presented new Mercedes-Benz Tourismo, which will see it once again lead the way for safety in its segment. The Setra ComfortClass 500 and TopClass 500 touring coaches, including the new S 531 DT double-decker bus, will also have ABA 4 on board from that time. ABA 4 is available free of charge to customers selecting the popular adaptive cruise control option, which provides the necessary radar technology for ABA 4.
