1. A computer-implemented method for controlling a host vehicle having a vehicle control system that controls motion of the host vehicle relative to a preceding vehicle, wherein the preceding vehicle is positioned immediately ahead of the host vehicle, comprising:

  • determining a relative headway distance between the host vehicle and the preceding vehicle with respect to a headway reference distance;

    determining a relative velocity between a velocity of the host vehicle and a velocity of the preceding vehicle;

    determining an acceleration rate of the preceding vehicle;

    receiving remote vehicle data transmitted from a plurality of remote vehicles to the host vehicle via a vehicle communication network and one or more communications links between the host vehicle and each of the plurality of remote vehicles, wherein one of the plurality of remote vehicles is a leading vehicle positioned ahead of the host vehicle and the preceding vehicle, and the remote vehicle data transmitted from the leading vehicle contains an acceleration rate of the leading vehicle;

    calculating an acceleration control rate for the host vehicle to maintain the headway reference distance between the host vehicle and the preceding vehicle, based on the relative headway distance, the relative velocity, the acceleration rate of the preceding vehicle, and the acceleration rate of the leading vehicle; and

    outputting the acceleration control rate to a vehicle controller to control motion of the host vehicle according to the acceleration control rate.
