Intelligent Lighting, Semi-auto Braking…
Posted on June 28, 2006 @ 10:22 amSome juicy details from the Mercedes Press Release on their 2007 Mercedes-Benz CL-Class:
Intelligent Light System: five lighting functions to match driving and weather conditions
The Intelligent Light System, which makes driving even safer in the dark, is equally unique. Together with bi-xenon headlamps it forms part of the standard specification for the new CL-Class and provides five different lighting functions that are activated to match driving and weather conditions: the new country road mode illuminates the driver’s-side edge of the road more widely and brightly than the existing low-beam headlamps. Motorway mode, which comes on automatically when driving above 90 km/h, delivers a uniform cone of light that illuminates the entire road width. In the centre of this cone the driver is able to see around 50 metres further. The enhanced fog lamps are also new, which Mercedes-Benz uses to provide better orientation in adverse weather conditions. Active light function and cornering light function are also part of the standard-fit Intelligent Light System on the CL Class.
PRE-SAFE®: automatic partial braking before an impending accident
Mercedes-Benz is the world’s first car brand to develop an anticipatory occupant protection system that recognises a potential accident situation in its early stages and takes anticipatory occupant protection measures: PRE-SAFE® is standard-fit on the new CL-Class. During emergency braking or when skidding is imminent, the system moves the passenger seat into the most favourable position so that seat belts and airbags have maximum effect on impact. It also inflates air cushions in the dynamic multicontour seats (standard in the CL 600), which envelop and support the driver and front passenger. PRE-SAFE® also closes the side windows and the sunroof in critical situations where high lateral dynamics are generated.
Mercedes-Benz has just made this multi-award-winning anticipatory protection system even better in the CL-Class with the newly developed PRE-SAFE® brakes. They operate in tandem with Brake Assist PLUS (BAS PLUS), which warns the driver of an imminent rear-end collision with visual and audible signals and automatically calculates the required braking pressure to prevent an accident. This braking-power support is available as soon as the brake pedal is
operated. If the driver does not react to the BAS PLUS warnings, the PRE-SAFE® brakes trigger automatic partial braking where an accident is imminent and slow the CL Class down using around 40 percent of the total braking power.
The automatic partial braking provides the driver with another clear warning to act. If the driver then immediately applies the brakes, the maximum braking force is available and the accident can - depending on the situation - be averted at the last moment. If an accident is unavoidable, the PRE-SAFE® brakes reduce the impact severity and, in turn, the risk of injury to the vehicle occupants.
As with Brake Assist PLUS, the new PRE-SAFE® brakes also utilise state-of-the-art radar technology to scan the situation in front of the car and detect a potential accident. Two short-range radar sensors with a range of 30 metres and a scanning angle of 80° are located behind the front bumper fascia on the CL-Class. The additional long-range radar in the radiator grille has a range of 150 metres.
Mercedes-Benz also offers BAS PLUS and PRE-SAFE® brakes in conjunction with the optional DISTRONIC PLUS proximity cruise control.
Assistance systems: radar sensors make parking child’s play
The newly developed parking guidance system (optional extra) also works on the basis of radar technology: the sensors measure the length of a parking space when driving past and show on the cockpit display whether there is sufficient space to park. Once reverse gear is engaged, the display then includes a symbolic representation of the parking manoeuvre; guide lines show the required steering angle and indicate the path into the parking space.
Night view assist with infrared headlamps, reversing camera, voice control for car radio, DVD changer and navigation as well as tyre pressure monitoring system are other optional Mercedes assistance systems for increased handling safety and comfort.
