Driver Fatigue Detection

The Driver Fatigue Detection System (also called Rest Assist) is available on certain models in our new Volkswagen and ŠKODA range. This helpful function senses fading concentration levels by intelligently measuring your pedal and steering wheel use, in addition to transverse acceleration. Particularly handy when undertaking a long journey, this system ensures that you stay alert and reduces the risk of getting into a road accident.

Why do we need this?

Accidents involving sleepy drivers tend to be particularly serious since the sleepy driver doesn’t have a quick enough reaction time, and is too slow to attempt to avoid an accident. Giving drivers early warning that they need to take a break is vital for safe travel.

How does the system work?

It monitors driver behaviour closely, noting any erratic steering wheel movements, pedal use and any lane deviations (working with Lane Assist), so that it can judge the moment when you start to feel sleepy and need to stop and take a break. It continuously evaluates your speed against traffic signals on the road, and works out when it may be time to take a break.

How does it warn the driver?

If the system detects that you might be starting to lose concentration, it will alert you with an acoustic signal, a visual message displayed on the instrument cluster and steering-wheel vibration.

While the Driver Fatigue Detection System works to alert you when you need a break, it is imperative that you realise that it is up to you – the driver – to make the decision to stop and take a break, for your safety and the safety of your passengers.
