COVER STORY

One of the significant features of the Telligent technology is the braking system which is a standard specification. It comprises a dual-circuit brake system, with internally ventilated disc brakes all round, ABS, ASR and auxiliary brakes such as the engine brake and retarder. The system relays each signal at lightning speed, much quicker than any mechanical system could. It allows braking power to be applied more sensitively as in a passenger car. The braking force is optimally distributed between tractor and trailer according to the load. The Telligent brake system also ensures that the brake pads on the different axles do not wear at significantly different rates. Telligent Stability Control recognises poten- tial instability, such as skidding or swerving and counteracts it where possible. Through systematic adjustment of engine torque, pre- cisely measured tractor braking and control of the trailer brake system, helps the driver to avoid tricky situations. The enhanced, additional safety feature inher- ent in the air bag integrated in the steering wheel, is linked to a control unit which ignites several propellants within a period of 30 milli- seconds as from a precisely defined minimum deceleration in the event of an impact.

device and draws the safety belt as close as possible to the driver’s body. In the event of an accident, kinetic energy is absorbed, to prevent direct contact between upper body and steering wheel. With the optional Telligent Safety Pack, Mercedes-Benz Trucks offers the ultimate Mercedes-Benz Safety Truck with Active Protection that no other manufacturer can currently offer in the local market. The pack consists of Telligent Distance Control and Active Brake Assist II. The Telligent Distance Control system con- sists of a radar sensor and control unit which controls the vehicle speed and supports the driver to automatically maintain the distance from the vehicle detected in front of it. Active Brake Assist II uses the existing ra- dar system of the Telligent Distance Control system which assists the driver when an accident hazard is detected and reduces the vehicle speed by staged braking inter- vention. During driving, Active Brake Assist II evaluates the traffic situation in front of the vehicle up to a distance of 200 m. The system uses vehicle data for this pur- pose and monitors the distance from vehi- cles driving in front as well as their speed. If the system detects the risk of a potential rear-end collision with a vehicle in front, the driver is informed by means of a three-stage

escalating warning system, corresponding to the actual situation. This warning gives the driver sufficient time to react. If there is no reaction from the driver to the collision warning, Active Brake Assist II au- tomatically initiates emergency braking (full braking application) if there is a vehicle in front. The warning concept for Active Brake Assist II is designed to allow drivers to take action themselves to avert critical situations. Mercedes-Benz Trucks continues to be the driving force for sustainable mobility in the future and is working intensively on further developments in all areas. With the optional Telligent Safety Pack, Mercedes-Benz Trucks offers the ultimate Mercedes-Benz Safety Truck with Active Protection that no other manufacturer can currently offer in the local market.
