Safety.

Adaptive Cruise Control (ACC) with Active Brake Assist 6 (ABA 6).

The Adaptive Cruise Control (ACC) with Active Brake Assist 6 (ABA 6) relieves the driver of the unnecessary stresses associated with maintaining a constant distance from the vehicle ahead, with a continuous measurement. ABA 6 additionally supports the driver in case of an imminent collision with stationary objects, moving objects and moving pedestrians.

Active Brake Assist 6.

The emergency braking system ABA 6 assists the driver by automatically initiating emergency braking if there is a risk of rear-impact collision with vehicles in front or stationary obstacles. It also detects moving or stationary persons and cyclists in front of the vehicle. The system reacts to this with an acoustic and visual warning to the driver as well as an automatically initiated partial braking or emergency braking.

Active Drive Assist 2.

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.

Anti-lock Braking System (ABS).

The Anti-lock Braking System (ABS) supports driving stability during critical braking operations and ensures that the vehicle remains steerable. The braking forces acting on the individual wheels are distributed by the ABS so that even in an emergency braking situation no wheel is blocked for any length of time, and the steerability of the bus is largely maintained.

Acceleration Skid Control (ASR).

ASR prevents the drive wheels from spinning in two ways. On the one hand, ASR minimises wheel spinning through a measured braking intervention. On the other hand, the torque of the engine is regulated via the "electronic accelerator pedal".

AquaBlade® windscreen wipers.

With its innovative profile, the flat wiper blade ensures that screen wash is evenly distributed on the windscreen. This increases comfort, saves screen wash and, due to the considerably better cleaning action, also ensures optimum visibility – ultimately a plus for safety.

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).

Continuous brake limiter (DBL).

The continuous brake limiter (DBL) is a safety system that makes it impossible, for example, to decouple the drivetrain by depressing the clutch pedal when going downhill. DBL constantly monitors the maximum permissible speed of the vehicle. If a vehicle exceeds the maximum permitted speed, e.g. when driving downhill, DBL communicates with the other safety systems.

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.

Electronic Stability Program (ESP®).

The Electronic Stability Program (ESP®) significantly reduces the risk of the vehicle skidding and tipping over by selectively braking individual wheels or by braking the vehicle as a whole.

Electro-pneumatic service brake system (EBS).

Exemplary safety even in unforeseen traffic situations - the electro-pneumatic service brake system (EBS) achieves shorter braking distances and less brake wear. The electro-pneumatic service brake system (EBS) increases road safety by improving braking stability and reducing braking distances.

Drive authorization system 4 (FBS4).

Start the vehicle without putting the key in the ignition: the keyless access system Keyless-Start (drive authorisation system 4 FBS 4) makes this possible. The electronic vehicle key only has to be located in the cockpit area, so it can remain in the driver's pocket. The engine is started by pressing the start button.

High beam assistant.

The function can be activated or deactivated. It is active from a speed of approximately 20 mph (35 km/h) and is automatically deactivated below a speed of approximately 15 mph (27 km/h). The function adapts to the illumination/brightness of the surroundings (no automatic switching on if there is sufficient street lighting).

Front Collision Guard (FCG).

The Front Collision Guard offers increased safety in the event of a head-on collision by means of a transverse profile behind which crash elements are located. Their absorber structure converts the impact energy into deformation energy. The transverse profile serves as a reliable underride guard. Since the driver’s work space is mounted on a massive frame component, it can be pushed backwards to maintain a protective space for the driver in the case of a frontal impact.

Hold function.

The electronic brake with hold function combines easier handling, more comfort and greater safety. When the bus is at a standstill, the vehicle is held by the service brake by pressing the brake pedal above a certain point, and the brake is automatically released when starting off. The function can be deactivated by a button.

Rain-light sensor.

The light sensor increases road safety by automatically switching on the driving lights depending on the current lighting conditions and thus improving the visibility of the roadway.

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.

LED headlights for low beam and high beam.

The low beam and high beam benefit from the outstanding luminous efficacy of the integral LED headlights, which also use significantly less energy than standard lights. They provide broad and precise illumination of the road. Another safety benefit is the temperature of the light, which is similar to that of daylight and makes the eyes tire less quickly. The LED lights assure a long service life and low degradation (decrease in luminosity).

Sideguard Assist 2.

Sideguard Assist 2 is a safety assistance system that supports the driver in critical situations when turning right or turning left when visibility is possibly restricted. The system is designed to help detect moving obstacles within the system limits, and warns the driver so as to avoid critical situations or reduce the consequences of accidents when turning off or changing lanes.

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.

Stable bodywork (body in compliance with ECE-R 66.02).

The strength of the bus body is also an important factor for the level of passive safety of a bus. With its resistance, the consequences of an accident can be avoided. The high rigidity of the bus body of our buses is enhanced by weight-optimised annular frames around the body.

MirrorCam.

The modern MirrorCam system provides a clear and full view of the road traffic. Equipped with high-resolution cameras, the driving safety is improved and the risk of accidents is minimised. The extended field of vision enables the driver to see pedestrians, cyclists and other road users in the surrounding area. This eliminates the blind spot when turning right.

Traffic Sign Assist (TSA).

The innovative Traffic Sign Assist offers maximum safety and comfort on the road. Thanks to GPS and camera support, the vehicle speed is constantly compared with the current traffic regulations.

Frontguard Assist.

Frontguard Assist is an advanced system that was specially developed to warn drivers of pedestrians located immediately in front of the vehicle and also to warn them of an impending accident. Whether you are pulling away or driving slowly (up to 15 km/h), the intelligent assistance system can detect potential collisions with unprotected road users.
