Provided are a vehicular motion control device and method such that, even when a vehicle is turning, the target trajectory can be followed while maintaining traveling stability, with a reduced sense of incongruity felt by the driver. This vehicular motion control device is equipped with: a target trajectory acquisition unit 1a that acquires a target trajectory for a vehicle to travel; and a speed control unit 1ca that increases or decreases the longitudinal acceleration generated in the vehicle, the longitudinal acceleration being positive in the vehicle travel direction. If the vehicle deviates from the target trajectory during turning, the speed control unit 1ca performs longitudinal acceleration control to increase or decrease the longitudinal acceleration.
