PROBLEM TO BE SOLVED: To enable a dependent mobile object (e.g. another vehicle) which is made to encounter an independent mobile object (e.g. own vehicle) to move as naturally as a read vehicle by utilizing feed-back control and also to make the encountering timing of these mobile objects hard to shift. SOLUTION: When the own vehicle 52 passes through a synchronization start point 60, the integrated moving distance of the own vehicle 52 from the own vehicle synchronization start point 60 and the integrated moving distance of the other vehicle 54 from the start of synchronization is obtained. The relative speed of the own vehicle 52 and the other vehicle 54 is obtained, and after that, in order to make a control variable the previously determined set value of the relative integrated distance, a coefficient for determined the speed is obtained by giving a proportional control and a derivative control to the deviation between the relative integrated distance and the set value, then acceleration/ deceleration speed is obtained from previously determined acceleration speed of the other vehicle 54 and the coefficient for determing the speed, and the speed of the other vehicle 54 is obtained from the speed of the other vehicle 54 and the acceleration/deceleration speed.
