Safety

A model of safety.

You can always rely on the high safety standard of your Setra. The next generation of the ComfortClass is no different. Revolutionary assistance systems such as Active Drive Assist 2, Active Brake Assist 5 and the 360° camera are exemplary in their class. This means the best possible protection and the greatest possible relaxation on the road – not only for your passengers and drivers, but also for you as an entrepreneur.

Setra's integral safety concept helps to proactively prevent accidents. It protects both passengers and driver and the more vulnerable road users. The next generation of the ComfortClass underlines the high safety standard with spectacular innovations in the field of assistance systems. Active Brake Assist 5 (ABA 5) is the world's first emergency braking assistant for coaches that can react to moving pedestrians with emergency braking. The optional Active Drive Assist 2 enables semi-automated driving in a bus for the first time. And the new optional 360° camera system gives the driver an all-round view of the traffic situation.

The list of new safety and assistance systems in the Setra ComfortClass in the area of active safety is long. It starts with the optional Active Drive Assist 2, which for the first time in a bus enables the driver to drive semi-automatically. It is based on existing assistance systems whose functionalities have been combined for Active Drive Assist 2. These include the further developed Predictive Powertrain Control (PPC), Lane Assist (SPA) and the new Active Brake Assist 5 (ABA 5). Only through their interaction can driving processes such as accelerating, braking, maintaining distance, steering and lane keeping be carried out automatically by Active Drive Assist 2. This applies to the entire speed range from 0 to 100 km/h on motorways and motorway-like roads. Particularly helpful in city traffic, on the other hand, is the new Active Brake Assist 5 (ABA 5) emergency braking system, which is fitted as standard. This works for the first time with a combination of radar and camera system. Compared to the previous ABA 4 system, the new system can react to moving persons not only with partial braking, but also with full braking up to a vehicle speed of 50 km/h. The new system can also react to moving persons with full braking. In unclear situations, the driver can also rely on the benefits of the optional 360° camera. The basis is formed by four cameras at the front, both sides and at the rear of the bus. The four images from the cameras are fused to create a 360° bird's eye view of the coach and its surroundings. And if you want even more visibility, you can opt for the new, even brighter full-LED headlights with Highbeam Assist. The antiviral filter sets that are part of the standard equipment of the ComfortClass prove that the topic of safety encompasses much more. For even more effective infection protection, driver protection doors, software updates or disinfection dispensers can be individually retrofitted.

Active Drive Assist 2 actively assists the driver with distance and lane keeping by combining various assistance systems. The system can brake, accelerate and keep the vehicle on track through active steering movements. To this end, it combines the functions of the individual systems in a unique way and thus already enables semi-automated driving in all speed ranges.

With Active Drive Assist, all assistance systems work hand in hand and support each other: Active Drive Assist, for example, acts according to the specifications of Predictive Powertrain Control (PPC) to ensure the most economical driving style possible. For the longitudinal and lateral guidance of the vehicle, the system uses functional enhancements based on the proven adaptive cruise control (ACC) and lane assist. Active Drive Assist also uses the same advanced radar and camera technology as Active Brake Assist 5 (ABA 5) to detect traffic ahead. In addition, an emergency stop function is implemented. This brings the vehicle to a standstill through moderate, automated braking if the driver no longer reacts.

The 360° camera system consists of four cameras that capture the immediate vehicle environment and generate an indirect all-round view. The associated 10" screen is located on the A-pillar above the cockpit. This system allows pedestrians, cyclists and obstacles to be seen even in areas that are otherwise not visible to the driver. In this way, the system increases road safety, as collision hazards can be detected and, at best, prevented.

The views from the 360° camera are available up to a speed of approx. 20 mph (30 km/h) when driving forwards and always when reversing. Note: Risk of accidents due to objects protruding into the traffic area above the cameras, e.g. protruding roofs, exterior mirrors of your own and other buses, etc. The cameras cannot detect these objects. Particularly in the 360° view, the impression of a free environment can be created even though objects above the mounted cameras protrude into the turning space.

ABA 5 supports the driver by automatically initiating emergency braking if there is a risk of a rear-end collision with vehicles in front or with stationary obstacles. It also detects moving or stationary persons in front of the vehicle. The system reacts to this with an acoustic and visual warning to the driver and simultaneous partial or full braking.

The driver can switch off Active Brake Assist 5 at any time, but the fifth generation, like the fourth, is technically so sophisticated and essentially designed in such a manner that this procedure only makes sense in rare exceptional cases. With the extended system limits of Active Brake Assist 5, accidents can be prevented even more reliably than before. Automated emergency braking on detecting moving persons offers a further plus in safety – especially for journeys in inner-city areas.

The Adaptive Cruise Control (ACC) with Active Brake Assist 5 (ABA 5) relieves the driver of the unnecessary stresses associated with maintaining a constant distance from the vehicle ahead, with a continuous measurement. ABA 5 additionally supports the driver in case of an imminent collision with stationary objects, moving objects and moving pedestrians.

As a further development of ABA 4, ABA 5 combines the use of radar and camera. Thanks to sensor fusion, the system can now react to people crossing, approaching or running in their own lane with an automated emergency stop within the system limits up to a vehicle speed of 50 km/h. This also applies to pedestrians who walk in front of the vehicle, are detected by the system while moving, and then suddenly stop. In snow, rain, fog, heavy spray, glare, direct sunlight or changing lighting conditions, the range and recognition of vehicles and persons can be impaired.

Sideguard Assist.

Sideguard Assist.

Sideguard Assist is a safety assistance system that supports the driver in critical cornering situations where visibility may be limited. When turning or changing lanes, the system is designed to help avoid critical situations, within its limitations, or reduce the consequences of accidents.

The function of the system and the warning concept were established based on the analysis of accidents while cornering that involved pedestrians and cyclists. In the majority of accident scenarios, the cause is due to the movement of both parties involved (vehicle and pedestrian/cyclist). In these cases, the system provides early information (yellow display) about moving persons or vehicles in a zone alongside and over the entire length of the vehicle and warns the driver as soon as the situation becomes critical (red).

Lane Assist (SPA).

Lane Assist (SPA).

With the aid of a camera system behind the windshield, the Lane Departure Warning system detects when the vehicle unintentionally leaves a marked lane. As soon as the vehicle crosses the markings, the driver is warned by a clear vibration on the corresponding side of the driver's seat.

Lane Assist (SPA).

Lane Assist (SPA).

The LDWS is activated from a speed of 40 mph (60 km/h). The lane assist system is switched off when the turn signal is activated, for example when the driver initiates a deliberate lane change. The system can be deactivated in the ICUC menu, e.g. in a construction site.

A small camera behind the windshield uses boundary lines to record the road directly in front of the vehicle. If the vehicle is about to cross any of the markings without a turn signal being activated, the driver is alerted by a pulsation in the seat. The camera determines the instant of warning based on the width of the lane, the distance to the marking line, and the speed of approach to the marking. The LDWS becomes active above a speed of 40 mph (60 km/h); it is switched off by operating the turn signal, for example when initiating a deliberate change of lane.
