Volvo is currently testing a device called Driver Alert that aims to counter the problem of driver fatigue, reports Channel 4 website in the UK.
Sleepiness at the wheel is thought to account for at least 10% of all road accidents and 20% of accidents on motorways, claiming more lives than drink-driving.
The same website reported back in January 2005 of a similar system being developed by Saab:
Saab has released details of its new safety system which detects if a driver is nodding off at the wheel. A number of manufacturers have been working on such systems, but Saab could be one of the earliest to put theirs into production.
It incorporates two miniature cameras with infra-red lenses which monitor the driver's eye and head movements; if they stray from the 'straight-ahead' position for more than two seconds, a buzzer sounds, and if they continue to fail to respond, a brake pulse will be delivered through the ESP system.
The system can apparently determine also whether the driver is looking in the rear-view mirror or round a corner, so will not sound a warning, and it can also distinguish between city driving and faster highways.
The software could also be used to determine automatic optimum settings for driver's seat position, steering wheel and mirrors, or to decide the best speed for airbag deployment in the event of an impact.
Saab's ergonomics chief Arne Nabo said this week: "The system is functioning extremely well in our testing. And there is no problem with the hardware, which is reliable and relatively inexpensive. We are now concentrating on fine-tuning the timing and nature of the final warning alarm."
Volvo's system is a little different from those being tested by other manufacturers, such as Saab's, which monitors drivers' eye and head movements. It uses a camera mounted between the windscreen and rear-view mirrors that monitors the distance between the car and the road markings, detecting if, for example, the car is drifting out of lane or moving in an uncontrolled way; it then sounds an alarm and displays a message on the control panel.







The name Vabis is derived from the name Vagnfabriksaktiebolaget i Södertelge or Södertälje Coachbuilding Company which was founded in 1891. The name Scania is derived from Scåne a competitor truck company from the south of Sweden. The two companies merged in Spring 1911 and became known as Aktiebolaget Scania-Vabis until 1969.
The first emblem to appear on a Saab automobile was that on the bonnet of the prototype Saab, the Ursaab. The symbol itself was nothing more than a fictitious heraldic symbol which did not appear in any Saab since.
This distinctive logo, signifying Saab's aircraft heritage, first appeared within the grid-pattern grille of the 1963 Saab 96. From 1967 onwards the logo, pictured (photographed from the bonnet of a Sonett II), appeared on the Sonett II and Sonett V4. The same badge was mounted above the boot handle on the Saab 96V4 until 1973/4.
Saab Automobile AB introduced the new corporate symbol of the red Gripen head and gold crown with the name SAAB in silver beneath it all contained within a blue roundel.
This logo was officially introduced on 14th August 2000, just months after the complete takeover of Saab Automobile AB by General Motors.
