ATTITUDE CONTROL DEVICE

As an example, an attitude control device of embodiments includes a calculator that calculates an acceleration in a front-rear direction by using a weight and braking driving force of a mobile object, and an acceleration in a left-right direction by using a vehicle speed and a turning radius, and calculates a target seat surface angle in the front-rear direction by using the acceleration in the front-rear direction, and a target seat surface angle in the left-right direction by using the acceleration in the left-right direction.
