The dual function camera system, developed with Vauxhall and Opel engineers and Hella, takes 30 frames per second and recognises road signs and lane markings up to 100 metres away.
When it finds a match in its software, the car displays the information on the dashboard instrument panel.
The system also monitors lane changing behaviour, including steering wheel and indicator usage, and uses this data to detect and warn the driver when they do anything differently.
Hans Demant, managing director of GME Engineering, says: “These new features follow Vauxhall’s philosophy of enhancing driving excitement by assisting drivers without reducing their level of control.
“That means the system gives drivers information, but it doesn’t intervene.”
Vauxhall will introduce the system as an option for the new Insignia, and plans to offer it on other models in future.
