Abstract
A car sickness inhibition device includes: a memory and a processor connected to the memory, the processor being configured to: acquire an acceleration a in a front-rear direction of a vehicle or angles of inclination θ of the head and upper body of an occupant sitting in a seat of the vehicle; and by using expression θ>tan−1(a/g)·(1), where g denotes gravitational acceleration, obtain from the acquired acceleration a an angle of inclination θ0 with which car sickness is inhibited, or obtain an acceleration a0 with which car sickness is inhibited.
Claims13
A car sickness inhibition device comprising:
- a memory and
- a processor connected to the memory, the processor being configured to:
- acquire an acceleration a in a front-rear direction of a vehicle or angles of inclination θ of the head and upper body of an occupant sitting in a seat of the vehicle;
- and
- by using expression (1) below,
- θ>tan−1(a/g) (1)
- where g denotes gravitational acceleration, obtain an angle of inclination θ0 with which car sickness is inhibited by assigning the acquired acceleration a into the expression (1), or obtain an acceleration a0 with which the car sickness is inhibited by assigning the acquired angles of inclination θ into the expression (1),
- wherein the processor is further configured to control adjustment of angles of the seat by seat angle adjustment devices so that the angles of inclination θ of the head and upper body of the occupant sitting in the seat of the vehicle each become equal to or greater than the obtained angle of inclination θ0 with which the car sickness is inhibited.
