Mercedes-Benz Attention Assist
Mercedes-Benz has spent some time studying those who nod off at the wheel, and it says it's developed a new "Attention Assist" technology that will help drowsy drivers stay alert.
The new system--which will be available in a new Mercedes-Benz in spring 2009, likely the next E-Class--monitors the flow of data from the car in motion--acceleration, braking and steering inputs. When minor inputs begin to vary from the established norm of that driving session, the Attention Assist system intervenes with an audible warning and a light on the dash that tells the driver to take a driving break.
Mercedes says 25 percent of serious accidents are caused by overtired drivers, and that drivers on the road for four hours react 50 percent slower than a fresh pilot. The risk of an accident is doubled in this time frame; after six hours of driving, it's eight times higher, they say.
