Motion Control Device for Moving Body

To improve fuel consumption of a vehicle by effectively performing acceleration/deceleration suppression control of a moving body such as a vehicle. A motion control device, configured to control a motion of a vehicle, includes: a travel distance acquisition unit which acquires a travel distance of the vehicle from a stop state to the next stop state of the vehicle; a travel distance storage unit which stores the travel distance; a next travel distance prediction unit which predicts the next travel distance of the vehicle from a stop state to the next stop state of the vehicle after having moved by the travel distance based on the travel distance stored in the travel distance storage unit; and a control determination unit which determines whether to perform control to suppress acceleration/deceleration in a movement direction of the vehicle. The control determination unit is configured to determine whether to perform control to suppress the acceleration/deceleration in the movement direction of the vehicle based on the next movement distance and a position of a preceding vehicle preceding the vehicle.
