A Parking Assistant at 61. Frankfurt Motor Show
Parking made easy through parking assistant at 61. Frankfurt Motor Show
A firework of innovations at Hella's booth
The retrofit bend-lighting system DynaView Evo2 is only one of the numerous innovations Hella will be showing at the IAA 2005 in Frankfurt. Further highlights on the booth, which covers 500 square meters in Hall 8.D05, include the completely new prototype of an LED headlamp with dynamic LED cornering light, an electronic parking-assistant system, a concealed rain/light sensor, inductive-switching interior lamps and new combination rear-lamp technologies such as 3D light guides and an LED light-curtain. The front-end specialist company HBPO, a Hella joint venture with Behr and Plastic Omnium, is presenting the innovative front-end of the future - IFP ((Integrative Front-End Philosophy) at the Hella booth. It integrates even more functions despite reduced weight and fewer components, and shows ways to intelligently solve more stringent pedestrian-protection requirements.
Together with its Japanese cooperation partner Stanley, lighting and electronics expert Hella is presenting an LED headlamp prototype with dynamic LED cornering light for the first time at the IAA 2005 in Frankfurt. In this full-LED headlamp the lighting specialists are realizing optical and lighting engineering innovations such as Cartoval plastic lenses and a so-called "light curtain" using LED technology, which give vehicle stylists a whole range of new opportunities for front-end design. For the first time, a dynamic cornering light that manages without mechanical components has been realized.
Hella electronics specialists have developed the world's first capacitive rain sensor for virtually invisible integration into the windshield. As the new concept for the first time unites the rain, light, humidity and solar sensor functions, it can replace up to three individual sensors. The sensor's aerial structure, which is completely integrated into the windshield, is barely visible. In the future this will allow areas of the windshield or rear window to be used for rain detection which have hitherto been less suitable for that purpose. Especially with contra-rotating wiping systems (butterfly principle) and panorama windshields, the advantage is that the sensor can be optimally placed in the wiping area without any restriction of the driver's view.
New is Hella's electronic parking assistant which enables the driver to automatically, comfortably and safely back into even narrow parking spaces. An ultrasound sensor automatically measures the length and width of a parking space while driving alongside it, even taking account of curbstones. If the parking space is large enough, the parking process may be started. The driver only operates the accelerator and brake pedals, while all steering is done automatically.
The new cornering light system "DynaView Evo2" is made up of two different auxiliary lamps (for right and left), each 90 mm in diameter, and an electronic control unit which is safely located in the engine compartment. The computer-calculated free-form reflectors have been specially designed for broad illumination of the areas alongside the front end of the vehicle. The light is provided by extremely powerful H7 halogen bulbs. With the low beam switched on, the cornering light is activated without delay when the indicator is set or automatically when driving round bends at speeds up to 40 km/h. Depending on requirements, either the right (in a right-hand bend) or left headlamp (in a left-hand bend) is switched on. When driving through bends, a yaw rate sensor measures the turning speed of the vehicle and supplies the switching pulse. After the bend, a dimmer gently switches the light level off again.
The cornering light provides additional safety when reversing, too: when the vehicle is put into reverse, both cornering lights switch on and illuminate the areas to the right and left of the vehicle broadly and brightly. A further advantage of "DynaView Evo2": the auxiliary lamps are also approved as fog lamps and can be activated by means of a separate switch as required.
