Stuttgart – According to the findings of development engineers at Mercedes-Benz following a fleet test conducted with a total of 1,000 Mercedes-Benz Actros trailer in 2005/2006, half of the serious truck accidents could be prevented. For the purposes of the trial, half of the trucks were equipped with the Lane Assistant, proximity control and stability control assistance systems. The number of accidents for the vehicles fitted with the safety package was shown to be halved compared to the 500 trailer with a conventional specification; furthermore, where an accident did occur, the cost of the damage was 90% lower. The results were derived based on an observation period of twelve months and a total distance travelled of 106 million kilo­metres.
The state-of-the-art assistance systems from Mercedes-Benz constitute a highly effective means of combating the principal causes of accidents, namely "rear-end collisions" and "veering off the road". It was for this reason that these driver assistance systems were developed as a matter of high priority and successively introduced from the year 2000 onwards, starting with the Lane Assistant. The accident prevention highlight to date is the Active Brake Assist system, which has been available for Mercedes-Benz trucks for nearly two years now. If, in the event of an imminent collision, the driver fails to react despite multiple warnings, this system will automatically initiate a full application of the brakes. While Active Brake Assist is not always able to avoid accidents, its application of full braking power is always able to reduce the impact speed and therefore considerably mitigate the consequences of the collision. The system has so far clocked up around 350 million kilometres in customer vehicles, with a consistently positive track record.
The rapid spread of these technologies is essential if a wide-scale improvement in road traffic safety is to be achieved. In view of this, financial support is now being
offered from several sides to facilitate their swift introduction. Mercedes-Benz, for instance, has put together attractively priced packages, which reduce the total cost by around a third compared to ordering the systems individually. Examples here include the Classic Safety Package and the Top Safety Package. In this way, it has been possible to boost the inclusion rate of the various options on the model variants they are available for by between 15% and 20%. Some motor vehicle insurers, such as Allianz, Daimler Financial Services, Kravag and Zürich Versicherung, offer premium discounts for trucks fitted with the corresponding safety features, while direct subsidies are available through the respective trade associations.
The assistance systems offered for Mercedes-Benz vehicles do not relieve drivers of their responsibility for driving safely. They can certainly aid them however by allowing them to concentrate better on the traffic around them, and can always come to their assistance whenever technology can react faster and more effectively than humans.

Telligent Lane Assistent: The Telligent Lane Assistant warns the driver when the vehicle is in danger of leaving its lane unintentionally. For this purpose it uses a camera to constantly monitor the distance between the vehicle and the lane markings. If the truck appears likely to cross the lane marking, the driver is alerted by a noise similar to that produced by a corrugated surface on the relevant side.

The emergency braking system mitigates the effects of accidents and saves human life: Derived from the proximity control system, this emergency braking system automatically initiates emergency braking action if it detects an impending collision with a moving obstacle. This substantially reduces the speed of collision, dramatically reducing the effects of an accident. The Active Brake Assist system of the Mercedes-Benz Safety Truck uses the three radar beams of the proximity control system. If the system detects a potential collision, the driver is first warned visually, then acoustically. If the driver does not respond, partial braking with approx. 30 % of full performance is initiated, followed by full braking if necessary.

Telligent proximity control: Telligent proximity control relieves driver workload on motorways and other trunk roads. When the system detects a slower-moving vehicle ahead, it automatically brakes the truck with a maximum of 20 percent braking power until a specific distance previously set by the driver has been restored. If the vehicle ahead accelerates, or if the truck driver changes to a clear road lane, the proximity control system automatically accelerates the truck back to its preset speed. This system is also the basis for the new emergency braking aid Acitve Brake Assist.
