1. In an anti-collision system for preventing a collision of a source vehicle with an object, including object-detecting means for detecting conditions of said object present in the vicinity of said source vehicle, said object including a traveling vehicle preceding said source vehicle, operating condition-detecting means for detecting parameters indicative of operating conditions of said source vehicle, and control means for controlling said source vehicle so as to prevent a collision thereof with said object, based on said conditions of said object detected by said object-detecting means, and said parameters detected by said operating condition-detecting means;

  • the improvement comprising;

    first estimating means for estimating a path of travel of said source vehicle, based on said parameters detected by said operating condition-detecting means;

    first setting means for setting an area of travel of said source vehicle to a first predetermined area including said path of travel of said source vehicle estimated by said first estimating means;

    second estimating means for estimating a path of movement of said object, based on said conditions of said object detected by said object-detecting means;

    second setting means for setting an area of movement of said object to a second predetermined area including said path of movement of said object estimated by said second estimating means; and

    calculating means for calculating a possibility of collision between said source vehicle and said object, based on said area of travel of said source vehicle set by said first setting means, and said area of movement of said object set by said second setting means; and

    wherein said control means is responsive to said possibility of collision calculated by said calculating means, for controlling velocity of said source vehicle.
