Modeling of Driver Takeover Reaction Time Under L3 Autonomous Driving Conditions

This paper investigates the influence of driver takeover reaction state on driving safety during L3 level self-limiting condition automatic driving takeover, focusing on the perspective of driver takeover reaction state, designs three takeover scenarios of pedestrian passage, forward obstacle, and right crosswind, and carries out takeover driving simulation experiments with multiple secondary task stimuli during the operation of the automatic system. The ErgoLAB human-computer interaction platform is used to realize the synchronous processing of multi-source data, and combined with the physiological characteristics of human factors and mathematical and statistical methods, the influence of each physiological characteristic on the driver’s take-over reaction time under the influence of human-vehicle-road multi-attribute factors is investigated, and then a scientific and reliable driver take-over reaction time model is established, which provides important references to the controllability and safety of the function of the self-driving car.
