The new MultiClass 500 raises the bar for safety in the low-entry segment. The robust frame design creates a protective cocoon. Advanced assistance systems such as Preventive Brake Assist 2 aid the driver and help to prevent accidents in a targeted way. LED headlights ensure optimal visibility. The electronic parking brake combines easy handling with high levels of safety.
Safety first – the new MultiClass 500.
Every new Setra means advanced assistance systems – and the MultiClass 500 is no exception. The innovative Preventive Brake Assist 2* warns the driver of a collision with stationary or moving objects. At the same time, it automatically initiates a braking manoeuvre with partial braking. Preventive Brake Assist 2 reacts to stationary and moving objects, including pedestrians and cyclists. Additionally, objects outside the carriageway, such as road signs, parked vehicles or traffic in adjacent and opposite lanes, are detected better within the system limits. The 360° camera system provides extra assistance, making the driver aware of pedestrians, cyclists and obstacles even in areas that would otherwise be difficult or impossible to see. The latest version of the Predictive Powertrain Control (PPC) intelligent cruise control is another crucial safety factor. PPC automatically reduces the speed when entering towns as well as before tight bends on country roads or obstacles such as roundabouts and stop or give way signs. This provides responsive and predictive driving. The new electronic parking brake provides a very different kind of functional aid: the system helps hill starts with an additional, integrated moving-off aid. It furthermore prevents the vehicle rolling accidentally if the driver stops, unfastens the seat belt and leaves their seat.
Actively seeking passive safety.
Despite all the assistance and safety systems, accidents can never be avoided. The developers of the new Setra MultiClass 500 have taken this into account as well. An optional underride guard reduces the effects of a rear-end or head-on collision. It protects the driver as well as the occupants of the other vehicle. Setra has also thought about the passengers: the comfortable Setra Transit and Setra Route seats are equipped with seat belts on request. Wheelchairs are securely fastened either with practical mushroom-head connectors and straps or with straps recessed in the platforms. The MultiClass 500 furthermore meets the rollover test requirements of ECE R 66.02 with its equally stable and lightweight annular frame design.
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.
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.
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.
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.
The roll lock is activated when the ignition is switched on. The basic function is to control and hold the brake pressure last controlled via the brake pedal at a standstill. The brake is then only automatically released during the start-up process. The release of the brake depends on the applied starting torque. In the case of longer downtimes, a warning message is sent after 10 minutes with the request to use the parking brake.
The roll lock can be deactivated by pressing the button. An indicator light in the button indicates when the functionality is deactivated. The function is reset by pressing the button again or after switching on the ignition again.
The rain sensor and automatic driving light are assist systems that activate automated functions by means of a sensor system and relieve the driver of routine tasks.
The rain sensor increases traffic safety, especially when driving in convoys, through individually adjustable, automated wiping functions.
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.
AquaBlade® windscreen wipers.
The windscreen wiper flat blade system with integrated screen wash supply in the wiper blade distributes cleaning fluid through several nozzles directly over the wiper blades on the windscreen.
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.
In addition, the flat wiper blade possesses excellent aerodynamics, which also reduces noise disturbance.
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.
Due to the electronic control of the EBS brake components, significantly shorter response times are achieved at the brake cylinders. The system distributes the brake pressure optimally to all axles, thereby ensuring the best possible braking effect. In the unlikely event of an electronic system failure, a dual-circuit pneumatic redundancy is available. This will still bring the coach safely to a halt. As a further development of the conventional air brake, the EBS offers numerous advantages. When braking, the control unit first activates the continuous brake (retarder and/or engine brake). If greater retardation is required, the control unit uses the information in the data network to determine the optimum braking pressure for every axle. The electropneumatic brake system enables shorter braking distances compared to a pneumatic brake system as well as significantly less brake disc and lining wear due to the integration of the continuous brakes described above.
In addition, EBS constantly monitors and optimizes brake pad wear axle by axle. This allows service and pad change times to be coordinated. Integration of wear-free brakes such as retarders and engine brakes (retarder integration) additionally protects the brake pads and leads to less brake pad wear. The overall result is reduced downtime and thus an improved cost-benefit ratio.
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.
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.
*Preventive Brake Assist 2 is optionally available for all models of the new Setra MultiClass 500 LE from spring 2024.
