MB launches speed limit warnings
Mercedes-Benz has unveiled two new driver warning systems, Speed Limit Assist and Lane Keeping Assist, which are set for introduction in the new E-Class and the S-Class from spring 2009.
The Speed Limit Assist system uses a windscreen-based camera and intelligent, electronic image processing to identify road speed signs and check the limit displayed. It processes the data within milliseconds before presenting an indication of the current speed limit on the cockpit display.
The speed limit remains visible until the speed restriction is lifted or changed.
Lane Keeping Assist warns the driver if the car leaves its lane unintentionally. A camera on the inside of the windscreen monitors the road markings and detects when the car leaves its lane. The camera can detect road markings by evaluating the difference in contrast between the road surface and the markings.
