Influence of Passive Fatigue and Take-Over Request Lead Time on Drivers’ Take-Over Performance

At SAE Level 3 of driving automation, human drivers are not expected to continuously control the vehicle or monitor the driving environment. However, due to system limitations, drivers would be prompted to intervene and “take-over” the vehicle in certain instances. This brings into question the capability of human driver to take control after being out of the loop for prolonged periods. Distractedness has been identified and modelled in previous studies however, paucity exists with regards influence of drowsiness in the absence of a secondary task on take-over performance. This study discusses the effect of parameters like take-over request lead time and the degree of driver’s drowsiness on take-over performance. Experiments were conducted in a high fidelity driving simulator on 12 licensed drivers. Results reveal significant influence of lead time and degree of drowsiness on different performance parameters. Subjective scores of drivers also correlated with objective parameters of drowsiness.
