Measurement of Sleepiness Depth based on Accelerator Operation

The authors verified the accuracy of an algorithm that determines the sleepiness depth based on accelerator operation by performing a circuit run using three cars. The accelerator foot pedal (or intake manifold valve) travel value was acquired from the controller area network (CAN) signal at runtime, and the sleepiness depth was measured at 1-min intervals using this algorithm. Based on the face image of the driver and a subsequent driver self-assessment, the timing results for the occurrence of weak sleepiness (Lv1) and strong sleepiness (Lv2) were investigated and compared to the results of this algorithm. A correct answer for Lv1 was given five points, and a correct answer for Lv2 was given two points. The correct answer prediction rates (prediction 15 min ago) for Lv1 and Lv2 were 60% and 50%, respectively. The authors consider these to be good results for an algorithm that is still in the early development stage.
