영문 초록

The purpose of this study was to quantitatively evaluate the effects of the secondary task with unexpected situation during simulated driving using the variable indicating control of vehicle. The subjects were participated 50s people including 15 males with 29.5±6.7 years of driving experiences and 15 females with 20.1±5.6 years of driving experiences. All subjects were instructed to keep a certain distance (30m) from the car ahead and a constant speed (80㎞/hr or 100㎞/hr). Sending text message(STM) and Searching navigation(SN) were selected as the secondary task. Experiment consisted of driving alone for 1 minute and driving with secondary task for 1 minute. It was defined driving phase and unexpected situation phase respectively. Medial-lateral coefficient of variation(MLCV) of car movement was analyzed for evaluating lane keeping in this study. In the results, MLCV was increased by 118.3% at 100㎞/hr. In the case of secondary task, MLCV in STN and in SN were increased by 235.1% and 290.3%, respectively. There was no significant difference between male and female. In case of driving at high-speed and with secondary task, it may be disturbed constant control of the vehicle when unexpected situation appeared suddenly.
