INNOVATIONS

The new development center

Preh has had its modern high-tech development building with plenty of space for creativity and innovation at its Bad Neustadt headquarters since 2017. One of the special features of the development center is the showroom, in which the latest innovations and concepts can be shown exclusively for Preh customers before their official presentation at international trade fairs.

  • HMI Design Concept

    The automobile of the future:
    Displays, touch screen, streaming

    The car of the future is versatile in terms of the interior, dashboard and center console. In autonomous driving, the multimedia display doubles in size and the steering wheel folds away. Functions are selected via integrated control elements, touch screen and touchpad with active, haptic feedback. Smart surfaces have integrated control elements.

  • Innovations you can touch

    Center stack operating system

    Preh presented innovative automotive control systems (HMI) for the center console (center stack) at the IAA. Central display contents can be moved to the instrument cluster using gesture control. When functions are selected on the touch screen, you get visual and haptic feedback. A rotary knob connects conventional, mechanical operating elements with the digital world of displays. Various functions can be accommodated in small spaces.

  • Innovations you can touch

    Control systems (HMI),
    Touchscreen in the car

    At the IAA, Preh Automotive showed new possibilities of integrating 'haptic landscapes' into a touchscreen. Up to now, the driver has not received any feedback from the system via a touchscreen when performing functions. The solution presented provides haptic feedback by pressing vibrating buttons and sliders on the screen. The driver thus receives noticeable feedback from his selection of functions.

New operating system concept

Preh shows new ways in HMI design with a vehicle door operating module concept. The module has a completely closed surface. Icons for function selection become visible when the hand approaches. They can also be felt through tactile contours and active haptic feedback confirms each function selected. 

Thanks to specially developed actuator and sensor technology, there are no moving parts. The operating module can thus be inserted into the vehicle door without a gap. Individual design of the perceptible contours and use of different surface materials are possible.

Innovation reports

  • "Invisible" LIN and CAN temperature sensors for the cockpit 

    The latest generation of Preh's fanless temperature sensors can be designed for the LIN and CAN protocol and enable new freedom for interior design. The part that is visible with conventional fanless temperature sensors can be integrated in the new Preh design-surfaces development. This makes the sensor completely invisible in the interior.

    Preh's temperature sensors with the CAN vehicle protocol standard integrate software necessary for temperature determination and contain the algorithm for air conditioning regulation. This enables higher data volumes and transmission speeds as well as significantly more functionalities. The air conditioning control device is relieved accordingly.

    Preh also offers fanless temperature sensors in combination with a humidity sensor to avoid defogging. The compact sensor module can be placed in the inside mirror base.

It is undisputed that vehicle interiors are increasingly being dominated by touch displays. Quite worn-out, conventional control elements are not far from becoming obsolete. Automotive supplier Preh shows with its concepts from pre-development and series solutions the optimal combination possibilities of both worlds. A tidy and clear design can be implemented by using touch displays and omitting most buttons and switches. For example, Preh has developed a completely integrated operating system for an electric 800V sports car, which includes touch display, carrier frame, electronics and haptic feedback module.

Active haptic feedback gives the driver clear, noticeable feedback when selecting a function. This means that his view is not distracted from the traffic and road safety is increased. Thanks to special actuator integration, Preh can completely stimulate the large display without vibrations being transmitted to other interior components. 

Preh meets customers' current design requirements with a "seamless design" haptic concept. The new door control module, which can be installed without gaps, has no moving parts and can be supplied in either plastic, glass, leather, wood or carbon optics. With Preh's "Seamless Design," no buttons are used; therefore, breakthroughs can be completely dispensed with. Feeling aids, i.e. depressions and elevations, in the surface contribute to better haptic orientation. 

A clear advantage of touch displays is they can be individually configured for different vehicle platforms. But rotary knobs have not lost their raison d'etre either. The combination of a haptic rotating bezel with touch display is being used in series production for the first time in the Ford Mustang Mach-E. Here the rotary knob is applied to the touch display using the pre-bonding process without any breakthroughs and reveals the display inside the ring. It is even possible to attach several such haptic rotating rings to the touch display, for more variability in the HMI design.

Preh offers even more possibilities with the latest development of a movable and even removable rotary knob. The freely movable control element can be maneuvered across the entire display and also personalized.

More safety in fog - sensor technology from Preh

In today's vehicles, sensors for monitoring tire pressure, rain sensors and automatic driving lights switching on at dusk are standard. This offers a significant improvement in road safety. However, the automatic light control can run the risk of incorrectly detecting emerging obstructions to the view due to fog, smog or smoke, because these can also occur during the day.

Standardized automatic light systems only control the low and/or high beam, front and rear fog lights still have to be switched on manually in the absence of special sensors. Preh plans to solve these problems with a new type of visibility sensor that makes use of the optical backscattering principle. Placed behind the windshield and emitting a beam of light invisible to the human eye with a wavelength of 850nm, microparticles, such as those found in fog, are illuminated and reflect this light. Microparticle concentration enables conclusions to be drawn about the concentration of water droplets in the air. This visibility sensor was extensively tested both in the laboratory and during real test drives and produced very good results. In addition, the visibility sensor was confronted with disruptive factors such as rain, snow, tunnels and forest sections. The sensor system remained fully functional even under these different environmental conditions.

Preh's visibility sensor can make a contribution to road safety in fog by enabling the lighting required to be switched on automatically. In the future, when vehicles are networked, the sensor data can also be passed on to the traffic behind, for early detection and avoidance of hazards.
