Safety

In our Mercedes-Benz motorcoaches, we drive the highest safety standards. Onboard the new Tourrider coach, a multitude of proven and upgraded safety and assistance systems guarantee drivers, passengers and other road users optimum protection. Additional protection is provided by the robust stainless steel body with integrated Front Collision Guard and energy-absorbing bumpers.

Mercedes-Benz coaches have always been leading innovators in the field of safety: In the 1970s, Mercedes-Benz was the world’s first manufacturer to present a bus with an anti-lock braking system (ABS). In the new Tourrider coach, the driver can depend on the support of numerous safety and assistance systems. Proven and newly developed systems such as Active Brake Assist 5, the ESP stability program, or the 360° camera underpin the Mercedes-Benz brand’s uncompromising commitment to safety and ensure a feeling of confidence and security for drivers, passengers, and other road users.

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 system evaluates images from the following cameras for this purpose: -rear-view camera (below the rear window) -front camera (below the windshield) -two side cameras (above the side windows) The function is limited in case of heavy rain, snowfall or heavy soiling of the cameras. The screen is divided into two sections. This provides five different views to choose from: Top View 360° (left image) and front camera (right image) Top View 360° (left image) and rear-view camera (right image) Top View 360° (left image) and left side camera (right image) Top View 360° (left image) and right side camera (right image) Top View 360° A corresponding selection menu is available on the screen.

ABA 5 supports the driver in an imminent collision with stationary objects, moving objects and moving pedestrians. If a collision is imminent, the ABA 5 can carry out automatic emergency braking within the system limits. The system can thus reduce or, in ideal conditions, completely prevent accidents.

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 30 mph (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.

Sideguard Assist is a safety assistance system that supports the driver in critical cornering situations where visibility on the right side (curb side) may be limited. When turning or changing lanes, the system is designed to help avoid critical situations within the system boundaries 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 accident happens from 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 beside and over the entire length of the vehicle and warns as soon as the situation becomes critical (red).

The high beam assistant automatically switches the high beams on or off depending on traffic, so that optimum illumination of the road is always ensured. When active, the system contributes to greater safety through improved lighting conditions and optimized illumination, and increases driving comfort and safety.

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).

The rain sensor and automatic headlights are assistance 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.

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.

High-performance electronics monitor the signals of ESP® sensors and continuously check whether the driver’s steering intention and the actual motion of the vehicle correspond. If the values differ, the system reduces the engine torque to restore the vehicle's balance and stability. If this is not sufficient, it additionally brakes individual wheels or the entire vehicle. The driver's deceleration request is respected at all times.

With the aid of a camera, 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 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.

By constantly comparing the data, the Brake Assist system continuously detects the speed at which the brake pedal is pressed. If this exceeds the usual level, the system automatically provides additional braking force withing fractions of a second. During such situations this significantly shortens the stopping distance of the coach.

The control unit also takes into account the speed, as well as the load of the coach. The BAS is a software function that builds on or uses the sensors and actuators of the EBS (electro-pneumatic braking system). Interventions by the BAS can lead to the intervention of other stability control systems, e.g. ABS. ...

The Adaptive Cruise Control (ACC) with Active Brake Assist 5 (ABA 5) relieves the driver by maintaining a constant distance – defined by the driver – from the vehicle ahead, based on continuous measurements. In doing so, 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.
