1. A driving control system comprising:

  • a host-vehicle position detecting means configured to detect a position of a host-vehicle;

    a host-vehicle speed detecting means configured to detect a speed of the host-vehicle;

    an acquisition means configured to acquire position information and speed information about another vehicle travelling towards the host-vehicle;

    a proximity position estimation means configured to estimate a proximity position at which the host-vehicle and the other vehicle approach each other based on the position and the speed of the host-vehicle and the position and the speed of the other vehicle;

    a proximity position changing means configured to change a proximity position to a first changed proximity position outside of a predetermined area, when the estimated proximity position is located in the predetermined area and the host-vehicle and the other vehicle travel on a same lane at a same time;

    a travelling plan generating means configured to generate a travelling plan that when the proximity position changing means has changed to the first changed proximity position, while both the host-vehicle and the other vehicle approach the first changed proximity position, after one of the host-vehicle and the other vehicle has passed through the predetermined area, and the other one of the host-vehicle and the other vehicle enters the predetermined area;

    a transmission means configured to transmit the travelling plan to the other vehicle; and

    a travel driving means configured to execute driving of the host-vehicle according to the travelling plan, wherein the proximity position changing means is further configured to;

    set a predetermined position threshold between the host-vehicle and the other vehicle in the predetermined area;

    change the proximity position to the first changed proximity position when determined that the estimated proximity position is closer to the host-vehicle compared to the position threshold so as for the proximity position to come closer to the host-vehicle outside of the predetermined area; and

    change the proximity position to the first changed proximity position when determined that the estimated proximity position is closer to the other vehicle compared to the position threshold so as for the proximity position to come closer to the other vehicle outside of the predetermined area; and

    wherein the travelling plan generating means is further configured to;

    generate the travelling plan that, when the proximity position has been changed to the first changed proximity position closer to the host-vehicle by the proximity position changing means, the host-vehicle is caused to decelerate and the other vehicle is caused to accelerate; and

    generate the travelling plan that, when the proximity position has been changed to the first changed proximity position closer to the other vehicle by the proximity position changing means, the host-vehicle is caused to accelerate and the other vehicle is caused to decelerate.
