Safety. Check!

Many safety and assistance systems have made their debut in a Setra coach. The next generation of the TopClass rigorously continues this tradition. With Active Brake Assist 5 (ABA 5), Active Drive Assist 2, even brighter LED headlights and the 360° camera, new and unique systems have been added. They support the driver and make bus journeys even safer.

Avoiding accidents, protecting vulnerable road users - that is the focus of Setra's safety development. An outstanding example of this is Active Brake Assist 5 (ABA 5). It is the world's first emergency brake assistant for coaches that can react to pedestrians with an emergency braking manoeuvre. A spectacular innovation in the field of assistance systems for coaches is the optional Active Drive Assist 2. For the first time in a bus, it offers the driver semi-automated driving in all speed ranges. And when manoeuvring, the next generation TopClass supports the driver with the optional 360° camera thereby helping to reduce accidental damage to the vehicle.

The next generation of the Setra TopClass shines with first-class safety equipment. A spectacular innovation in the field of assistance systems for coaches is the optional Active Drive Assist 2. For the first time in a bus, it offers the driver semi-automated driving in all speed ranges. To this end, existing and proven systems and technologies have been further expanded in their range of functions; they work together in Active Drive Assist 2. This includes the advanced Predictive Powertrain Control (PPC) cruise control, Lane Assist (SPA) and the new Active Brake Assist 5 (ABA 5). Accelerating, braking, maintaining distance, steering, staying in lane – Active Drive Assist 2 represents a decisive step towards automated driving with buses. It is active in the entire speed range from 0 to 100 km/h on motorways and motorway-like roads. At low speeds, for example when manoeuvring, the 360° camera shows its full potential. The basis is formed by four cameras: one at the front, one on each side and one 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. The new, even brighter integrated full-LED headlights with Highbeam Assist show that even good things can be improved. Thus, in the best Setra tradition, the next generation of the TopClass once again shows itself to be a true safety bus. Incidentally: the same also applies to the best possible protection against infection for drivers and passengers. Antiviral filters are part of the standard equipment of the TopClass. Other measures such as driver safety doors, software updates or disinfection dispensers are available as retrofit solutions.

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.

1. Close-range radar: 130° I range 70 m
2. Long-range radar: 18° I range 250 m
3. Mono camera: 25° I Range up to 600 m

All assistance systems work together with Active Drive Assist 2: to ensure the most economical driving style possible, the system acts according to the specifications of the Predictive Powertrain Control. The system uses functional extensions based on the tried-and-tested adaptive cruise control and the active lane assist for longitudinal and lateral vehicle guidance. To detect the traffic ahead, Active Drive Assist 2 uses the same advanced radar and camera technology as Active Brake Assist 5.

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.

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).

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.

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.

Tyre Pressure Monitoring (TPM).

Tyre Pressure Monitoring (TPM).

The wireless tyre pressure monitoring with indication in the multifunctional display is an electronic safety system that permanently monitors the air pressure of all tyres. Tyre pressure losses are displayed within the system limits.

Tyre Pressure Monitoring (TPM).

The right tyre pressure contributes to driving safety and significantly reduced fuel consumption. Even a tyre pressure set 0.5 bar too low can increase fuel consumption by up to 5%. The wheel electronics are positioned on the valve on the inside of the rim. The sensors record the data relevant to the tyre pressure and transmit it to the display instrument. The tyre pressure is recorded both when the vehicle is stationary and when it is moving. Caution! A sudden loss of pressure, for example due to the penetration of a foreign body, is not immediately indicated by the tyre pressure monitoring system. Damage to the tyres that does not lead to acute pressure loss is also not detected by the monitoring system. Here, visual inspection by the driver is and remains essential.
