However, the initial signs of fatigue can be detected before a critical situation arises. Bosch Driver Drowsiness Detection can do this by monitoring steering movements and advising drivers to take a break in time. The required information is provided either by the car&#8217;s electric power steering system, or by the steering angle sensor which is part of the car&#8217;s ESP\u00ae anti-skid system. The feature can therefore be installed cost-effectively and helps further increase road safety. Bosch Driver Drowsiness Detection can be used in passenger cars and light commercial vehicles, and can also be integrated into various control units in vehicles. It was first introduced as a standard feature in 2010, in the new Volkswagen Passat. The latest model with the function is the new Passat Alltrack.<\/p>\n<p><img data-recalc-dims=\"1\" decoding=\"async\" alt=\"\" src=\"https:\/\/i0.wp.com\/tomdenton.org\/blog\/wp-content\/uploads\/2012\/03\/032912_1958_DrowsinessD11.jpg?w=980\" \/><\/p>\n<p>The influence of fatigue on accidents has been demonstrated in a number of studies. In 2010, the American Automobile Association (AAA) published an analysis based on the accident data collected by the National Highway Traffic Safety Administration (NHTSA) in the United States. The assessment showed that overtired drivers were at the wheel in 17 percent of all fatal accidents in the US.<\/p>\n<p>Fading concentration and fatigue compromise the driver&#8217;s steering behaviour and response time. Fine motor skills deteriorate, and steering behaviour becomes less precise. The driver corrects small steering mistakes more often. The new driver drowsiness detection function is based on an algorithm which begins recording the driver&#8217;s steering behaviour the moment the trip begins. It then recognizes changes over the course of long trips, and thus also the driver&#8217;s level of fatigue. Typical signs of waning concentration are phases during which the driver is barely steering, combined with slight, yet quick and abrupt steering movements to keep the car on track. Based on the frequency of these movements and other parameters, among them the length of a trip, use of turn signals, and the time of day, the function calculates the driver&#8217;s level of fatigue. If that level exceeds a certain value, an icon such as a coffee cup flashes on the instrument panel to warn drivers that they need a rest. The Bosch Driver Drowsiness Detection function addresses an important aspect of the driver&#8217;s condition, and can thus contribute to improving road safety.<\/p>\n<p>Automotive Technology is the largest Bosch Group business sector. According to preliminary figures, its sales came to 30.4 billion euros, or 59 percent of total group sales, in fiscal 2011. This makes the Bosch Group one of the leading automotive suppliers. Worldwide, more than 175,000 Automotive Technology associates work in seven areas of business: injection technology for internal-combustion engines, powertrain peripherals, alternative drive concepts, active and passive safety systems, assistance and comfort functions, in-car information and communication, as well as services and technology for the automotive aftermarket. Bosch has been responsible for important automotive innovations, such as electronic engine management, the ESP\u00ae anti-skid system, and common-rail diesel technology.<\/p>\n<p>The Bosch Group is a leading global supplier of technology and services. According to preliminary figures, more than 300,000 associates generated sales of 51.4 billion euros in the areas of automotive and industrial technology, consumer goods, and building technology in fiscal 2011. The Bosch Group comprises Robert Bosch GmbH and its more than 350 subsidiaries and regional companies in some 60 countries. If its sales and service partners are included, then Bosch is represented in roughly 150 countries. This worldwide development, manufacturing, and sales network is the foundation for further growth. Bosch spent more than 4 billion euros for research and development in 2011, and applied for over 4,100 patents worldwide.
