Vehicle control device and vehicle control method

A vehicle control device comprising:

• a head movement prediction model that finds, relative to a head movement of a passenger in a left-right or roll direction caused by vehicle motion in the left-right or roll direction, a change in the head movement of the passenger in the left-right or roll direction caused by the vehicle motion in a front-rear or pitch direction different from the left-right or roll direction;
• and
• a vehicle motion generation unit that generates the vehicle motion in the front-rear or pitch direction to reduce the head movement in the left-right or roll direction on the basis of the head movement prediction model;
• wherein the head movement prediction model is a dynamic model of a spring-mass-damper having parameters different for each passenger;
• and
• wherein the vehicle motion generation unit generates the vehicle motion in the front-rear or pitch direction to suppress a motion sickness susceptibility index calculated from an output of the dynamic model.
