In 2008, Volvo introduced two new elements of active protection , Driver Alert Control (check the driver's alertness) and Lane Departure Warning (warning to leave the lane). The automaker is well aware of the number of accidents resulting from driver's inattention. According to the American Society of NHTSA in the U.S. causes fatigue at the wheel every year about 100,000 traffic accidents in which killed about 1,500 people and another 75,000 of them are injured.

Driver Alert Control examines the car ride away and the way the system is able to anticipate the driver's risk of reduced concentration. The system operates automatically at speeds above 60 km / h DAC monitors the movement of vehicles on the road and can tell controlled ride since uncontrolled. According to Daniel Levin, the chief responsible for the development of Driver Alert Control system, its function is very reliable. Even more reliable than the systems monitoring the driver's eyes. DAC is unable to even recognize a situation where a driver is too devoted to your phone or children in the rear.

The system consists of cameras located under the rear-view mirror, sensors and control unit. The camera is pointing outwards from the vehicle and constantly monitors the driving direction and distance from the vehicle markings. Other sensors detect the movement of cars in all directions. The control unit then records the data and compares well with the stored values. If the control unit detects driver fatigue, and sends an acoustic signal on the dashboard lights up the coffee cup symbol. System is even able to evaluate the driver's fatigue pětiškálové scale.

All, of course, remains the responsibility of the driver. The system only highlights the weakness and fatigue of attention, which could result in an accident.
