VEHICLE CONTROL DEVICE, VEHICLE CONTROL METHOD, AND VEHICLE CONTROL SYSTEM

According to an aspect of the present invention, a vehicle control device, a vehicle control method, and a vehicle control system acquire a setting condition including at least one of information related to a driving environment of a driving road on which a vehicle travels and information related to a state of the vehicle; set, based on the setting condition, an interval between trajectory points representing a target trajectory along which the vehicle is caused to travel; and output a control command that causes the vehicle to travel along the target trajectory. This makes it possible to prevent the driving performance of a vehicle from decreasing even when the conditions surrounding the vehicle change.
