Abstract: With the rapid development of the automotive industry and the advancement of mobile communication technology, In-Vehicle Information System shifted from traditional button to touchscreen. However, while enriching the drivers' driving experience, there are also certain potential driving distractions when operating touchscreen IVIS during the driving process. This study takes the operation of touchscreen IVIS by the driver as the secondary driving task, and designs a simulated driving experiment to explore the im-pact of the operation of secondary tasks on driving safety from driving performance, secondary task performance and EEG. Research has shown that low load operation tasks can easily cause drivers to be distracted, while high load operation tasks can affect drivers' judgment ability and occupy too much action resources. And when the difficulty level increases, drivers develop a compensation mechanism to complete secondary tasks through self-regulation.
