N2 - To research the influence of the secondary task on driving performance at different speed, the driving simulation experiment of four specified speed conditions and four secondary task conditions was designed. The mental workload of 16 driving conditions was evaluated by DAIL subjective scale. The changes of time required to complete secondary tasks, speed maintenance ability, lateral lane keeping ability and mental workload under different driving conditions were analyzed, and the effects of driving mental workload on speed maintenance and lateral lane keeping were analyzed. The results showed that speed and secondary task type have significant differences in secondary tasks completion time and driving mental workload, but their interaction has no effect on secondary tasks completion time or driving mental workload. For different secondary tasks, the mental workload has a quadratic function relationship with the speed, and the mental workload increases rapidly with the increase of the speed. The increase of the mental workload reduces the speed maintenance ability and makes the throttle input value smaller and stable. There is no significant relationship between mental workload and lane keeping ability, but the increase of the mental workload makes the steering wheel input value larger but more unstable.
