Driver Alert Support (DAS) uses the same forward-facing video camera and image analyser as Lane Keeping Support (LKS), plus a new, highprecision yaw rate sensor placed next to the system ECU, located behind the passenger seat, together with a vehicle speed sensor With DAS monitoring the truck's position in relation to the road markings, if a driving pattern is detected which Volvo describes as "irregular" (i.e, the vehicle drifts unchecked across the white lines), the driver gets an audible alert and a warning message in the dashboard driver information display. If that irregular pattern continues, the driver is again cautioned to stop and take a break.
