To provide an inter-vehicle distance control device which realizes inter-vehicle distance control that can be satisfied by a driver.SOLUTION: An inter-vehicle distance control device comprises: a preceding vehicle speed calculation part which calculates a speed of a preceding vehicle on the basis of a speed of an own vehicle and a relative speed between the own vehicle and the preceding vehicle; a target inter-vehicle setting part which sets a target inter-vehicle distance between the own vehicle and the preceding vehicle on the basis of the speed of the preceding vehicle; a target track generation part which generates a target track, which defines a time history of an inter-vehicle distance from an initial inter-vehicle distance to the target inter-vehicle distance, and a target track differential value which is a differential value of the target track; and a feedback control part which calculates a feedback acceleration command by multiplying a deviation between the target track and the inter-vehicle distance and a deviation between the target track differential value and the relative speed respectively by a gain. The device outputs the feedback acceleration command as an acceleration command.SELECTED DRAWING: Figure 1

    【課題】ドライバが満足できる車間距離制御を実現した車間距離制御装置を提供する。【解決手段】自車の速度と先行車との相対速度に基づいて先行車の速度を演算する先行車速演算部と、先行車の速度に基づいて先行車との目標車間距離を設定する目標車間設定部と、車間距離の初期値から目標車間距離に到達するまでの車間距離の時間履歴を定義する目標軌道、および目標軌道の微分値である目標軌道微分値を生成する目標軌道生成部と、目標軌道と車間距離との偏差および目標軌道微分値と相対速度との偏差に、それぞれゲインを乗算してフィードバック加速度指令を演算するフィードバック制御部と、を備え、フィードバック加速度指令を加速度指令として出力する。【選択図】図1
