Volvo cars introduces new systems for alerting tired and distracted drivers


Driver Alert Control, a unique bit of technology that promises to alert tired and distracted drivers, has been introduced by Volvo auto manufacturers.

Studies show that up to 90% of all traffic accidents are caused by driver distraction. Now Volvo Cars introduces Driver Alert Control - with a technology solution that is a world-first in passenger cars. The system aims to alert the driver when his or her concentration level is affected, for instance during long journeys. Another new system, Lane Departure Warning, alerts the driver if the car crosses one of the road markings without an obvious reason.

Lane Departure Warning and Driver Alert Control will be part of the same option package, called Driver Alert System. It will be available in the Volvo S80, V70 and XC70 at the end of 2007. “Real life safety is the key to our safety philosophy. When it comes to preventive safety, we have the same approach as when we develop protective systems.

In other words that our research and technical development focus on areas where new technology can create significant results in real-life-traffic,” says Ingrid Skogsmo, Director of the Volvo Cars Safety Centre. Based on the accident statistics above, Volvo Cars is focusing on developing efficient technology to help drivers avoid or reduce the severity of accidents caused by distraction and driver fatigue.

Driver Alert Control (DAC) - a unique innovation
As a result of extensive studies on how drivers operate behind the wheel, Volvo has developed Driver Alert Control - a world-first innovation that registers the car''s progress on the road and alerts unconcentrated drivers. Driver fatigue is a major traffic-safety problem the world over. According to the US NHTSA (National Highway Traffic Safety Administration), drivers who fall asleep at the wheel cause about 100,000 accidents annually in the United States alone, resulting in 1,500 fatalities and more than 70,000 injured drivers and passengers. The situation is similar in Europe.

The German Insurance Association GDV estimates that about 25% of all fatal accidents on the German Autobahn are caused by driver fatigue. Volvo’s Driver Alert Control is an important innovation. It is primarily intended for situations where the risk of losing concentration is the greatest and where an accident would have severe consequences. For example a straight, smooth road that lulls the driver into a sense of relaxation and where the risk of distracting activities or falling asleep is higher. The system steps in at 65 kilometers per hour and stays active as long as the speed exceeds 60 kilometers per hour.

Registers what’s happening on the road
Driver Alert Control monitors the car’s movements and assesses whether the vehicle is being driven in a controlled or uncontrolled way. This method is unique among vehicle manufacturers and is very reliable. “We do not monitor human behavior - which varies from one person to another - but instead the effect that fatigue or decreased concentration has on driving behavior. Our system is based on the car’s progress on the road. It gives a reliable indication if something is likely to go wrong and alerts the driver before it is too late,” explains Daniel Levin, project manager for Driver Alert Control at Volvo Cars.

He adds: “We often get questions about why we have chosen this concept instead of monitoring the driver’s eyes. The answer is that we don’t think that the technology of monitoring the driver’s eyes is mature enough yet.” Driver Alert Control can also cover situations where the driver is focusing too much on his/her cell phone or children in the car, thereby not having full control of the vehicle. “This is a positive side-effect of our concept, and this is possible since the system evaluates driving behavior rather than human behavior,” says Daniel Levin.
