1. A vehicle control system comprising:

  • a map information outputting means for outputting map information including a road on which a subject vehicle travels;

    a subject-vehicle position detecting means for detecting a subject-vehicle position on a map;

    a traveling state detecting means for detecting a traveling state of the vehicle;

    a steering means for steering a steering control wheel of the vehicle;

    a steering-torque applying means for applying a steering torque to the steering means;

    a steerage control means for determining a steering-torque application quantity based on the traveling state of the vehicle and a shape of a road ahead of the subject-vehicle position on the map, and for controlling said steering-torque applying means based on said steering-torque application quantity;

    an ahead-traveling vehicle detecting means for detecting at least one of a distance between the subject vehicle and an ahead-traveling vehicle and a relative speed of the subject vehicle relative to said ahead-traveling vehicle;

    a follow-up travel control means for controlling the subject vehicle to adjust the distance between the subject vehicle and said ahead-traveling vehicle to allow the subject vehicle to travel while following said ahead-traveling vehicle in accordance with at least one of the distance between the subject vehicle and said ahead-traveling vehicle and the relative speed of the subject vehicle relative to said ahead-traveling vehicle; and

    a control switch-over means which discontinues a steerage control by said steerage control means when a follow-up travel control by said follow-up travel control means is started during the steerage control, and which starts the steerage control by said steerage control means when said vehicle control system fails to detect said ahead-traveling vehicle during the follow-up travel control by said follow-up travel control means.
