Vehicle Control Device, Vehicle Control Method, and Vehicle Control System

In a vehicle control device, a vehicle control method, and a vehicle control system according to the present invention, in control of a motion of a vehicle which is based on a signal relating to a target trajectory and a signal relating to a traveling state, a target traveling state of the vehicle after a predetermined time period corresponding to a delay element in the control of the motion of the vehicle is predicted, and a command for achieving the predicted target traveling state is output to an actuator configured to control the motion of the vehicle, thereby suppressing occurrence of a deviation of a traveling trajectory from the target trajectory and occurrence of an unstable behavior, for example, meandering, due to the delay element in a vehicle motion control system which is based on the target trajectory.
