Key result
A fusion model using ECG HRV and driving behavior detects severe fatigue with ~98% accuracy.
Why the study?
Existing driving fatigue detection technologies have delayed identification, high error rates, and lack quantified causal relationships between physiological and behavioral indicators.
Comparison
ECG heart rate variability indicators vs driving behavior data across four simulated fatigue stages
Design
Four-stage standardized simulated driving experiment

A multimodal fusion model combining ECG HRV and driving behavior data accurately detects driving fatigue stages, reaching 97.8% accuracy for severe fatigue.
Wáng et al. (2026) studied Driving fatigue. Physiological-behavioral fusion fatigue assessment model was evaluated on Correlation between indicators and accuracy of the fatigue assessment model (|r| ≥ 0.75). A physiological-behavioral fusion model combining ECG heart rate variability and driving behavior data detected severe driving fatigue with 97.8% accuracy and a response time of ≤0.5 seconds.
