Driving fatigue is an important cause of traffic accidents. Numerous researchers have investigated the relationship between fatigue and eye indicators. Most research focuses solely on comparing eye indicators between awake and fatigue. However, driver fatigue is a gradually accumulated procedure, and different fatigue states have different indicators and different effects on driving safety. This study was undertaken to find the rules of eye indicators changing when the driver was under different fatigue. Based on the Tongji 8 degree-of-freedom (DoF) Driving Simulator, 15 eye indicator samples were collected using the Smart Eye. The driver's fatigue was divided into five levels, including:awake, mild fatigue, moderate fatigue, severe fatigue and extreme fatigue. The results showed that all eye indicators increased slightly before the driver enters a mild fatigue state. However, at a level of severe fatigue, the percentage of eyelid closure (PERCLOS), variable coefficient of pupil diameter and blink duration increased significantly, but blink frequency decreased slightly.
