Abstract
To achieve both guarantee of safety related to vehicle control and improvement of availability in an in-vehicle device that cannot independently perform automatic driving and needs assistance of vehicle control. To achieve the above object, a control system includes an in-vehicle device and a coordination device that are synchronized in time point. The control system includes a travelable time calculation unit that calculates a travelable time for guaranteeing that a vehicle does not collide with an obstacle on a travel trajectory in a target region through which the vehicle equipped with the in-vehicle device passes, a travelability determination unit that determines validity of the travelable time, and a trajectory following unit that permits the in-vehicle device to follow the travel trajectory when it is determined that the travelable time is valid.
