PROBLEM TO BE SOLVED: To provide a control apparatus, including a wireless device for obtaining preceding-vehicle information containing requirement acceleration Gs of a preceding vehicle therefrom through wireless communication, which controls the acceleration of the vehicle itself so that the acceleration thereof equals requirement acceleration Gj of the vehicle itself.SOLUTION: A control apparatus performs: calculating, as FB requirement acceleration GFB, acceleration required for a vehicle itself in order to maintain an inter-vehicular distance D between the vehicle itself and a preceding vehicle at a target inter-vehicular distance Dtgt; calculating, as FF requirement acceleration GFF, acceleration required for the vehicle itself for causing the vehicle itself to tracking-travel tracking a preceding vehicle, on the basis of the requirement acceleration of the preceding vehicle; calculating a total value of the FF requirement acceleration and FB requirement acceleration as requirement acceleration Gj of the vehicle itself; and setting the FF requirement acceleration at zero, in a case where a set position of a shift lever of the preceding vehicle is at a shift position other than that for moving forward the preceding vehicle, with the FF requirement acceleration larger than zero.SELECTED DRAWING: Figure 4 【課題】本制御装置は先行車の要求加速度Ｇｓを含む先行車情報を無線通信にて先行車から取得する無線装置を備え、自車の加速度が自車の要求加速度Ｇｊになるように自車の加速度を制御する。【解決手段】本制御装置は自車と先行車との間の車間距離Ｄを目標車間距離Ｄtgtに維持するために自車に要求される加速度をＦＢ要求加速度ＧＦＢとして算出し、先行車の要求加速度に基づき自車を先行車に追従走行させるために自車に要求される加速度をＦＦ要求加速度ＧＦＦとして算出し、ＦＦ要求加速度とＦＢ要求加速度との合計値を自車の要求加速度Ｇｊとして算出する。本制御装置は先行車のシフトレバーの設定位置が先行車を前進させるためのシフト位置以外にシフト位置にあり且つＦＦ要求加速度がゼロよりも大きい場合、ＦＦ要求加速度をゼロに設定する。【選択図】図４
