Abstract:In the last decade in-vehicle systems have developed to an important and integral part in the car industry. These systems are supposed to help the driver in crucial situations and deliver information to the driver, who then can react accordingly and keep him or herself and the surrounding safe. But to keep driving safe, the systems have to give reliable information and the systems should not distract the driver. A rather disastrous situation may occur when information systems provide wrong information in a situation when the driver is distracted. Therefore, we investigated the effects of valid and invalid advanced information for the performance of lane change manoeuvres in a simulated driving environment. The manoeuvers were either performed in a control condition without secondary task or in two blocks of dual task condition. Distraction was realized by a secondary task, which had to be performed during the primary driving task. The main findings of the study are that as in previous studies participants without any advanced information had longer reaction times than with advanced information and that the performance of the participants in the distracted situation improved over time due to less errors and an increase in the performance of the secondary task. In contrast to our expectations reaction time and error analyses did not provide hints that preparation was affected by dual task load. Also, in contrast to our expectations invalid advanced information did not differ from neutral information. The findings may suggest, that distraction has no effect on valid and invalid advanced information. However, alternative explanations may be possible and are addressed in the discussion of the results.
