With the S 531 DT, you will always know what is ahead – in terms of road traffic as well as your planning. With this in mind, the S 531 DT ensures marvelous relaxation not only for your passengers, but also for you. This begins with Setra’s high safety standard which delivers the best possible protection during the journey. And this is where the S 531 DT is way ahead in the world of the double-decker coaches.
The latest generation of driving assistance systems pick up on the environment more precisely than ever before, they react with foresight and prevent dangerous situations from arising in the first place. The state-of-the-art safety concept also takes into account the people outside the vehicle.
The Active Brake Assist ABA 4 recognises pedestrians moving up to 80 metres in front of the vehicle, in almost all traffic situations. This ensures maximum safety in the city as well as on long-distance routes. Additionally, the S 531 DT is the world’s first coach to provide the optional Sideguard Assist feature, which offers even more protection for pedestrians and cyclists when turning.

360° camera.
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.
Active Brake Assist 4 (ABA 4).
Active Brake Assist 4 (ABA 4) warns the driver prior to a collision with an obstacle and brake the coach independently if necessary.
Active Brake Assist 4 (ABA 4).
Active Brake Assist 4 (ABA 4) is a safety assistance system that supports the driver when an accident risk is detected by means of a three-stage warning concept up to full braking and can reduce the speed of the vehicle. It detects stationary and moving obstacles as well as moving persons within the system boundaries. Independent of the function of the proximity control system (ART), Active Brake Assist 4 warns the driver of a collision with an obstacle and brakes the bus independently if necessary. The radar-controlled system continuously scans the traffic lane at a distance of up to 250 metres ahead of the bus.
Sideguard Assist.
Makes turning even safer: Sideguard Assist warns the driver of moving or stationary objects next to the vehicle – and thus also protects other road users.
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).
Tyre Pressure Monitoring (TPM).
Tyre Pressure Monitoring (TPM) displays the current pressure in the individual tyres and warns of deviations from the optimum pressure. This reduces tyre wear, has a positive effect on fuel consumption and prevents dangerous tyre damage.
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. 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.
Attention Assist (AtAs).
Attention Assist (AtAs) is a safety assistance system that can help prevent microsleep. It thus contributes to improved driving safety, especially on long journeys and when driving at night. The system warns the driver visually and acoustically when it detects typical signs of overtiredness or inattention and prompts him/her to take a break. The warning is independent of the electronic logging device (ELD).
To analyze driving behavior, the steering movements are evaluated and an individual driver profile is created from them. The evaluation of the steering style is based on a stored algorithm. It evaluates steering errors made by the driver. At the beginning of the journey, the system first “learns” the driver's steering profile – this only occurs at speeds above 37 mph (60km/h). During the journey the custom steering behavior learned in this manner is then constantly compared in an electronic control unit with the driver’s current steering behavior and the respective driving conditions. A warning with a symbol (coffee cup in the display) appears when the current steering style deviates from the steering profile learned by the system.
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.
Electronic Stability Program (ESP®).
The Electronic Stability Program (ESP®) significantly reduces the risk of the vehicle skidding and overturning by counteracting the vehicle’s breakaway or overturning through targeted braking of individual wheels or by fully braking the vehicle.
