PLATOON TRAVELING SYSTEM

A platoon traveling system includes a control device that controls traveling of an own vehicle in adaptive cruise control that adjusts a vehicle speed of the own vehicle in such a manner that following a preceding vehicle at a certain interval is performed. Further, when a preceding vehicle having a high wind-shielding effect is detected on a front side of the own vehicle by a detection device provided in the own vehicle while the own vehicle is traveling alone in the adaptive cruise control, and a vehicle speed of the preceding vehicle is higher than an ACC set vehicle speed set as a vehicle speed in the adaptive cruise control of the own vehicle, the control device proposes to increase the ACC set vehicle speed by a predetermined increase range to a passenger of the own vehicle by using a proposal device provided in the own vehicle.
