Drowsiness and attention detection systems assess the driver’s alertness (for example by monitoring how long someone has been driving or by analysing how the steering wheel is being operated) and warn the driver to take a break when needed.
Drowsiness and attention detection systems are part of the ‘second wave’ of active safety measures – using cutting-edge technology such as on-board sensors, radar, cameras, GPS and lasers – that is being fitted to passenger cars.
Active safety technology can prevent accidents from happening altogether or at least actively help the driver to reduce the impact of an emergency situation. Active systems give the driver more control in dangerous situations. To that end, various safety systems constantly monitor the performance and surroundings of a vehicle.
Simply put, active safety systems avoid or mitigate an accident pre-impact – so before it happens or contact is made.
