Driving a car at low rpms causes torsional vibrations that passengers perceive as a hum. A new type of centrifugal pendulum helps reduce these vibrations. Fraunhofer researchers presented a prototype of this pendulum at the 2013 Hannover Messe.

If visibility is poor, thermal cameras can warn drivers of people or animals on the road. Yet such devices have been very expensive – until now. An important step has been taken to manufacture them more cheaply. A new process will make the infrared lenses – a component of such cameras – up to 70 percent cheaper.

Vacant parking spaces in town are thin on the ground. Finding one is just as tiresome as making sure you have the right change for the parking machine. An adhesive microchip on the windshield will make things much easier by unlocking the door to cashless parking.

Conserving energy is a top priority for auto manufacturers today. Laser technology can help. Lasers can be used to process thin light-weight components made of fiber-composite materials, as well as to manufacture more efficient engines and more powerful batteries.

Surface welding instead of penetration welding, allows a laser to produce a weld that is only visible on one side. But how do you control the laser power to prevent it burning a hole through the sheets of metal? A new camera system analyzes thermal images in real time – and ensures a perfect weld.

In the automotive industry, combustion engines are still assembled mostly manually. Researchers from Fraunhofer are developing procedures and methods to automate assembly processes to continuously improve the quality of the engines. The use of the latest technologies helps to eliminate uncertainties during engine assembly.

Networking vehicles with one another and with the infrastructure gives the driver information on the situation beyond his or her field of vision and warns the driver about accidents or traffic jams.
