NEW BRAKING TECH DEBUTS ON DAIMLER EURO CITY BUSES
STANDEES’ SAFETY during any emergency bus situation is at the forefront of the thinking behind Daimler’s new optional Preventative Brake Assist feature for all Euro Citaro and Conecto Mercedes-Benz city buses, the company announced recently.
Preventative Brake Assist cleverly applies a warning system and only partial braking automatically in the event a vehicle needs to rapidly reduce speed before coming to a halt – the latter still at the directive of the driver.
In doing so, the impact of the kinetic energy and momentum on passengers standing on packed buses is lessened, no doubt reducing the chance of them being ‘thrown around’ and incurring unforeseen injury.
The overall product safety roll-out will see the new Active Brake Assist 4 - 10 years in development and now also automatically initiating a braking manoeuvre for pedestrians in the form of partial braking - as standard from 2019 on all touring coaches from Mercedes-Benz and Setra, with the new Preventive Brake Assist now optional for city buses. Additionally, on both buses and coaches, Sideguard Assist – the first turning assistance system for city buses and touring coaches, it’s claimed – is optional.
According to Daimler, “preventing accidents and protecting more vulnerable road users
… is the utmost priority in the safety concept of the premium bus and coach brands Mercedes-Benz and Setra.”
EVOLUTION OF TECH
Active Brake Assist was the first emergency braking assistance system for buses and coaches when it was introduced 10 years ago as an option, and in its fourth generation is now being transferred to all touring coaches from Mercedes-Benz and Setra, says Daimler.
Active Brake Assist was enhanced with each generation. Whilst it at first initiated emergency braking only for moving vehicles ahead, Active Brake Assist 3 initiated automatic emergency braking for stationary obstacles in addition, and was capable of actively preventing even more accidents, it’s stated. Active Brake Assist was one of the main triggers for the mandatory introduction of automated emergency braking systems in touring coaches from autumn 2015 in the EU, it says.
The new Active Brake Assist 4 is the first emergency braking assistant for buses and coaches to automatically initiate a braking manoeuvre for pedestrians, too. As explained by the company, “in this case all options are open to the driver: warn the pedestrian using the horn, evade them with the bus or carry out an emergency stop. The basis for ABA 4 is the multi-mode radar system with a combination of long-range and short-range radar.”
Till Oberwörder, head of Daimler Buses, said: “By taking this step, we are making our already safe buses and coaches even safer. We are certain that Active Brake Assist 4 will not only prevent accidents, it will save lives.”
