Next, Nissan Motor (Nissan) DS is introduced. It was announced in the 2018 fiscal year.

In NISSAN, the purpose of the use of DS is that the evaluation using the actual vehicle is dangerous, such as how the driver is affected by the driver assistance system and whether the driver can deal with the dangerous situation. Therefore, because the use of DS is indispensable, the development purpose was to make DS which can continue to ride for a long drive.

In order to continue to ride DS for the long drive, DS without motion sickness must be developed. Especially, it is said that the drivers with long driving experience and rich driving sense are easy to cause the motion sickness. Therefore, the sense of incongruity due to the difference in driving sense between actual vehicle and DS was reduced, and DS with presence and less motion sickness was aimed at.

At present, though the cause of the motion sickness is not perfectly clarified, there is a "sensory conflict" theory as the one which can explain the sickness most. This is that the sense that the driver feels in driving the actual vehicle and the sense of incongruity due to the difference in the sense that the DS feels cause motion sickness. This difference in sensation can be roughly classified into the following two.

(1)Somatosensory: Difference or delay between the acceleration felt in a real vehicle and the acceleration reproduced by DS
(2)Vision: The difference and delay between the scene actually seen and the images on the DS
