A vehicle motion control method controls a motion state of a vehicle during a vehicle transient motion in which an acceleration in a lateral direction is generated in the vehicle. The vehicle motion control method includes: setting a corrected longitudinal acceleration for correcting a basic longitudinal acceleration determined in accordance with a required driving force for traveling of the vehicle; and determining a target longitudinal acceleration from the basic longitudinal acceleration and the corrected longitudinal acceleration, and operating a traveling actuator of the vehicle based on the target longitudinal acceleration. A direction and a magnitude of the corrected longitudinal acceleration are determined from a viewpoint of suppressing a change in a posture of an occupant of the vehicle in a roll direction.

Method and device for controlling vehicle motion during acceleration in the lateral direction

Provided is a vehicle seat device that includes a headrest to support a head of an occupant seated on a vehicle seat. The vehicle seat device includes a rest operation adjustment mechanism provided on the headrest and to restrict or allow movement of the head of the occupant seated on the vehicle seat and a controller that controls the rest operation adjustment mechanism to allow the movement of the head of the occupant when a frequency of a vibration in a width direction of a vehicle is equal to or larger than a predetermined value.

Vehicle seat device and control method for vehicle seat device

An occupant posture control method is provided that can suppress motion sickness. The occupant posture control method predicts a vehicle motion based on information relating to the vehicle motion, and imparts a stimulus that generates a muscle tension such that the occupant assumes a posture corresponding to the vehicle motion, when a predicted vehicle motion occurs.

Occupant posture control method and occupant posture control device

A system for use with an automotive vehicle supported on front and rear pairs of road wheels to detect a drop in a tire air pressure for each of the road wheels. When the vehicle is detected as operating substantially in a steady straight line driving condition, the road wheel having a dropped tire air pressure is specified based on the angular speeds of rotation of the respective road wheels. This detection is made based on the angular road wheel speeds in view of changes in loads exerted in the respective road wheels caused by the tire air pressure drop.
