A preceding-vehicle follow-up control apparatus is arranged to calculate a target vehicle speed for following-up a preceding vehicle at a target vehicle-to-vehicle distance. The target vehicle speed is calculated from an equation having a form of a linear combination of a form which includes a linear connection between a product of a first gain and a difference between the vehicle-to-vehicle distance and the target vehicle-to-vehicle distance and a product of a second gain and the relative speed. The control apparatus controls a driving apparatus and a transmission apparatus of a vehicle so as to adjust a vehicle speed at the target vehicle speed. This enables the vehicle-to-vehicle distance to be converged into a target value without excessively increasing or decreasing the relative speed during this follow-up control.
