Mirror supplier Gentex can thank the German autobahn for providing it with a crucial piece of information that could give the company a huge advantage when pitching an up-and-coming technology to automakers such as BMW, Porsche and Mercedes-Benz.
The U.S. company’s full-display mirror (FDM) combines a conventional mirror with a high-tech camera monitoring system, giving the driver two different ways to see what is behind him or her.
The second image comes from a rear-facing camera, which provides a wider field of view than a conventional mirror.
Most of Gentex’s feedback about its system, which is offered in models such as the Cadillac CT6 and Range Rover Evoque, had come from customers in North America because the solution has been slow to catch on in Europe.
“Europe has been the laggard,” Brad Bosma, Gentex vice president of vision systems and dimmable glass, told Automotive News Europe.
To address this, Gentex teamed up with the Adrive Living Lab, which is part of Germany's University of Applied Sciences Kempten, to get feedback on its product from customers in Europe's largest market.
While most of the feedback from the testers in Germany matched what Gentex has heard from customers using the product in North America, the big difference was that there was more motion in the image that was created from the camera when traveling at high speeds.
Bosma said that to correct the issue Gentex can change the field of view at higher speeds and/or blur the perimeter of the image so that the driver does not see the motion.
“It’s not a huge technical challenge,” he said. “We just didn’t know we needed to do this.”
With this knowledge, Gentex will be in a better position to add German automakers to the customers it already has for the FDM, which also include Nissan, Chevrolet and Buick.
Gentex says it is the global leader for the product and it expects to deliver 500,000 FDMs this year, just four years after the product debuted.
