Active Brake Assist 4: ABA 4: the first active emergency braking assistance system with pedestrian detection for high-decker touring coaches

Stuttgart / Split
  • The ABA 4 is available in the new Tourismo from spring 2018
  • ABA 4 warns the driver and triggers braking
  • Multi-mode radar systems with a range of up to 250 metres
  • Active Brake Assist: more capable with each generation

Mercedes-Benz has traditionally been a leader in safety and assistance systems. Now a new chapter begins with the new Active Brake Assist 4 (ABA 4) with pedestrian detection in the Tourismo high-deck touring coach: for the first time anywhere in the world an emergency braking assistance system in a high-deck touring coach automatically brakes for pedestrians. Active Brake Assist is thus stepping up the performance to an even higher level.

ABA 4 warns the driver and triggers braking

Avoiding accidents and protecting more vulnerable road users are central facets of safety development at Mercedes-Benz. 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 metres

In technical terms, Active Brake Assist 4 with pedestrian detection is based on new-generation radar technology which also features in the latest Mercedes-Benz passenger cars and trucks. The electronically scanning multi-mode radar comprises long and short range radar systems. The long-range radar detects multi-track vehicles and obstacles in a direct line in front of the touring coach up to a maximum distance of 250 m, single-track vehicles such as bicycles up to 160 m and pedestrians 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 full braking for vehicles in front and for stationary obstacles. Mercedes-Benz 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 Mercedes-Benz: since November 2015, emergency braking systems have been mandatory for newly approved touring coaches and trucks. Already the standard AEBS version of the new Toursimo 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 be available in spring 2018 for the new Mercedes-Benz Tourismo, once again making it the benchmark in its class where safety is concerned. 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.
