An inter-vehicle distance control device (100) comprises a delay distance calculation unit (103) and a delay distance compensation unit (107). In a traveling scene in which the speed of a leading vehicle LV changes, control is carried out in such a manner that a delay distance Ddelay resulting from a delay in a vehicle speed control unit (12) is calculated, and in consideration of a delay distance compensation vehicle speed command VFF_delay * for compensating for the delay distance Ddelay for a vehicle speed command V * , the actual inter-vehicle distance is made to match a target track Dtrk * to reach, from the initial value of the inter-vehicle distance, a target inter-vehicle distance after acceleration/deceleration of the leading vehicle.
车间距离控制装置(100)具备延迟距离运算部(103)和延迟距离补偿部(107),在先行车辆LV的速度变化的行驶场景中,运算因车速控制部(12)的延迟引起而产生的延迟距离(Ddelay),考虑用于对车速指令(V*)补偿该延迟距离(Ddelay)的延迟距离补偿车速指令(VFF_delay*)来进行控制以使实际的车间距离与从车间距离的初始值至到达先行车辆加减速后的目标车间距离为止的目标轨道(Dtrk*)相一致。
