| 摘要： | An experiment was conducted which evaluated driver intervention during an adaptive cruise control deceleration behind a lead vehicle. Ten men and ten women in two age groups experienced system controlled decelerations from a cruise speed of 70mph (113km/h) to a following speed of 55mph (89km/h) behind a confederate lead vehicle on the highway. Following the presentation of thirteen successful decelerations, one which appeared to require driver intervention was presented. Prior to intervention, foot position ranged from a point directly below the brake pedal to 16.4in (41.7cm) from the brake pedal. Foot motion began between 21.1s time-to-collision (TTC) and 4.0s TTC. Approximately eighty percent of the participants paused to "cover" the brake before final motion to activate the brake. TTC upon brake activation ranged from 6.1s to 3.7s. The older age group intervened (braked) later than the younger age group. Driver braking after intervention ranged from 0.16g to 0.32g. |
