Comfort concerns a generic concept and motion sickness is the most important affecting factor in transportation. Still, car sickness is (was) not a big issue in the automotive industry. This is because 2/3 of all car occupants are drivers and drivers typically do not suffer from carsickness that much. In automated driving, however, all occupants will be passengers, and of all passengers, 2/3 does suffer from carsickness at some point. This, however, only holds when automated vehicles would continue driving as human drivers do. To take advantage of the automation of motion control, knowledge of the relationship between carsickness and vehicle motion is imperative. ISO 2631-1 is currently the most acknowledged standard offering a numerical model of such this relationship. This standard was developed to predict seasickness aboard large ships, which motions are mainly perturbed by the swell.
