To improve the performance of tracking a subsequent vehicle in a tracking travel system.SOLUTION: A tracking travel system 1 for making a subsequent vehicle 2F travel by tracking a leading vehicle 2L includes: a leading vehicle sensor 9L which is disposed in the leading vehicle, and acquires a travel state of the leading vehicle containing an accelerator opening; a hydraulic brake device 6 which is disposed in the subsequent vehicle, and applies brake torque to the subsequent vehicle according to a brake fluid pressure; a subsequent vehicle control device 12F which is disposed in the subsequent vehicle, and capable of controlling the hydraulic brake device; and an inter-vehicle communication device 11 which transmits the travel state of the leading vehicle containing the accelerator opening acquired by the leading vehicle sensor to the subsequent vehicle control device. When the accelerator opening of the leading vehicle is returned at a prescribed speed or faster, the subsequent vehicle control device executes preload processing for instantly increasing the brake fluid pressure of the hydraulic brake device.SELECTED DRAWING: Figure 3
【課題】 追従走行システムにおいて、後続車の追従性能を高める。【解決手段】 後続車2Fを先導車2Lに追従走行させる追従走行システム1であって、先導車に設けられ、アクセル開度を含む先導車の走行状態を取得する先導車センサ9Lと、後続車に設けられ、後続車にブレーキ液圧に応じた制動トルクを付与する油圧ブレーキ装置6と、後続車に設けられ、油圧ブレーキ装置を制御可能な後続車制御装置12Fと、先導車センサによって取得されたアクセル開度を含む先導車の走行状態を後続車制御装置に伝達する車々間通信装置11とを有し、後続車制御装置は、先導車のアクセル開度が所定以上の速度で戻されたときに、油圧ブレーキ装置のブレーキ液圧を瞬間的に高める予圧処理を実行する。【選択図】 図3
