BMW has unveiled a new car that can read speed limit signposts and variable limit signs and display this information on the instrument cluster. With this technology, drivers are always aware of the speed zone they are in and adjust their driving accordingly especially on roads that have several different speed zones depending on traffic flow.
A small camera installed near the interior mirror constantly monitors the signs along the road and compares this with data saved in the navigation system. The camera will be able to read painted metal signs as well as dynamic digital displays. The date recorded by the camera is given priority and the speed allowed is displayed through the instrument cluster or in the head-up display on the car’s windscreen. This will significantly reduce the risk of breaking the speed limit by mistake.
Still, the BMW Speed Limit Display is an information system only. It will not intervene in the control of the vehicle or its speed. Maintaining a correct and safe speed is still the sole responsibility of the driver. The new Speed Limit Display will be available in the new BMW 7 Series set to be unveiled in Europe later this year.
