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(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.
