Abstract:
The investigation of drivers’ take-over performance when switching from working on different nondriving related tasks (NDRTs) while driving with a conditionally automated driving function (SAE L3) is an important human factors topic in current vehicle automation research, as drivers are required as a potential fallback during the automated drive. In the current study, conducted in a static driving simulator, a replication of a previous on-road study using a Wizard-of-Oz vehicle was pursued. N = 21 participants with previous experience with automated driving functions participated in the experiment. After approximately 5 minutes of automated driving on a highway while working on different NDRTs, users were requested to take back vehicle control in noncritical situations. A detailed comparison of take-over times between both studies using survival analysis is reported. Results support relative validity of both research environments towards each other regarding the general level of take-over times after various NDRTs, but also exemplify differences regarding the absolute distribution of take-over times. Additional parameters like perceived criticality and lane positioning are discussed.
