| Abstract: | This study aims to study the effects of high, medium, and low levels of immersion of non-driving-related (NDR)tasks on the takeover behavior under automated driving. Test scenarios are developed using a driving simulator. There are four takeover scenarios developed based on the task of non-driving-related activity(entertainment and work task)and time to collision(5 s and 10 s). To collect data on takeover behavior, volunteer drivers are recruited for a driving simulation. In order to measure takeover behavior, four metrics are used: speed, lateral deviation, responding time, and takeover correct time(TCT). The results show that: ①the vehicle speed decreases as the immersion level of NDR tasks decreases, and the deceleration rate increases after taking over the vehicle. When the time to collision is 5 s, the level of immersion of NDR tasks significantly affects lateral deviation. ②When the time to collision is 10s, the level of immersion of NDR tasks has a weaker significance on the takeover response time (p =0.056 < 0.1), and it decreases as the immersion level increases(low immersion level=3.94 s; medium immersion level=3.45 s; high immersion level=3.21 s). A significant difference between the level of immersion of NDR task and the time of takeover has been found(time to collision 5s: p =0.031 < 0.05;time to collision 10 s: p =0.019 < 0.05). That is, the time for takeover decreases as the level of immersionofNDR tasks increases. ③ With the same NDR task, the takeover responding time decreases as the immersion level increases. According to the results of statistical analysis, the interaction between NDR tasks and their immersion level does not affect the response time for takeover significantly, however, it does affect the TCT. |
