Further exhibit highlights include a steering wheel with integrated lenticular switches (LTK technology), a gear lever with an innovative haptic design and control devices for electric vehicle battery management.
"Preh has always stood out from the crowd with its keen spirit of invention. The control systems and control devices on display at the IAA once more make it clear how our partners can count on us in the future," said Dr. Michael Roesnick, chairman of the Preh Executive Board.
Under a black panel surface, the new center console has a screen that displays a wide range of menus that are selected via a rotary and push knob with an integrated touchpad: navigation, telephone, multimedia and memo-board. In the sub-menus, the function selection can be done via the touchpad. For example, under the memo-board menu in the "write" mode, all characters written with one finger are displayed. A "draw" mode has also been integrated. Here, everything that the operator's finger draws on the touchpad is shown on the screen.
The center console also has a climate control system with three control knobs. As a special feature, when you touch a control knob, a pop-up menu opens that offers detailed selection options for the climate settings. In addition, touch-sensitive surfaces are also integrated in the black panel surface, with button functions and acoustic feedback.
Ease-of-use with strong visuals and perfect haptics
Further highlights of Preh’s IAA exhibit are innovative concepts for the gear lever and steering wheel.
Preh's innovative buttons with LTK display technology contribute to ease-of-use in the steering wheel. This Preh technology enables the assigning of more than one function to the buttons and, only the specific function icon that is required is actually displayed. For easy differentiation, the corresponding icon can also be coded with a different color. This means that more functions can be allocated to the steering wheel without more buttons being required. This means optimum operation of the multifunction steering wheel buttons is ensured with an ideal ergonomic positioning for the thumb.
About the newly developed gear lever concept that stands out, thanks to its precise magnet haptics, Preh Director of Sales, Marketing and Project Management Christoph Hummel said, "Our control systems not only offer perfectly functioning innovative solutions, but far more than this, their design and haptics ensure a high-quality appearance and a stronger presence for our customers' car brands."
Battery management control devices for E-vehicles
Preh is also presenting innovative control devices for hybrid and electrical vehicles in Frankfurt, which are designated as Battery Management Units (BMU) and Cell Supervisory Circuits (CSC). The task of the CSC is to permanently monitor the voltage and the temperature of every single battery cell. Information about the charging status and temperature is forwarded by the CSC to the battery management unit. By means of a so-called "passive balancing," this ensures that charging differences between the battery cells are balanced out, as balanced charging and use of the batteries extends their lifespans. In this promising market sector for the battery management of E-vehicles, Preh now has its first production contract.
Founded in 1919, Preh is a globally operating group of enterprises with more than 2,600 employees in Germany, Portugal, Mexico, the U.S.A., China and Romania. Preh is headquartered in Bad Neustadt a.d. Saale, Germany. The company achieved revenues of € 351 million in 2010. Preh’s development and production competencies focus on vehicle interior control systems, sensor systems, electronic control units and assembly systems for the world’s leading vehicle manufacturers.
