Learn how to manage fatigue with the Driver Safety System. A Driver fatigue technology and monitoring system alerting mine site operators to a microsleep

Instant Fatigue Detection

How It Works

Driver Safety System (DSS)

By the end of 2016, the Driver Safety System had recorded more than 570 hours of drivers operating while asleep* and 1.5 million distraction events

Technology Expert David Edwards explains how the Driver Safety System (DSS) fatigue technology provides instant driver fatigue and distraction intervention for tired operators


Approximately 40% of nighttime employees admit to nodding off during their shift.

With fatigue technology you can instantly mitigate the risk of driver fatigue for tired operators.

Learn how to manage fatigue with the Driver Safety System, a non-intrusive, in-cab fatigue detection technology that instantly alerts operators the moment fatigue or distraction is identified. The fatigue technology works by monitoring eye-closure duration and head pose. If the Driver Safety System detects a fatigue or distraction event the operator is immediately alerted through configurable in-vehicle seat vibration and / or audio alarm.

The driver fatigue or distraction event detected by the Driver Safety System is sent to a 24-hour monitoring centre to classify and confirm the event. Caterpillar experts will analyse the data and provide customised reporting with site-level recommendations. By cross-referencing fatigue and distraction events against available equipment data, Caterpillar can provide suggestions to improve operational efficiency such as hard breaking and over speed.


*Hours operating while asleep are recorded during the silent phase of a Fatigue Risk Assessment; prior to the DSS vibration and audio alerts being turned on for operators. Sleep is not achieved once the DSS is taken out of silent mode since immediate intervention takes place at the onset of a fatigue event.
