1. An adaptive cruise control apparatus for an automotive vehicle, comprising:

  • a vehicular velocity detecting section that detects a velocity of the vehicle;

    an inter-vehicle distance detecting section that detects an inter-vehicle distance between the vehicle and another vehicle which is traveling on the same traffic lane as the vehicle in a forward direction thereof;

    a driving force controlling section that controls a driving force for the vehicle to maintain the inter-vehicle distance at a target inter-vehicle distance to achieve the following run control when the inter-vehicle distance detecting section detects the inter-vehicle distance between the vehicle and the other vehicle and to maintain the velocity of the vehicle at a set vehicle speed when the inter-vehicle distance detecting section detects no other vehicle on the same traffic lane in the forward direction thereof; and

    an acceleration controlling section that sets an acceleration value at an initial stage of an acceleration in such a manner as to be larger than that at a later stage of the acceleration when the inter-vehicle distance detecting section transfers its other vehicle detection state from the detection state of the other vehicle to a non-detection state thereof.
