1. vehicle headway maintenance assisting device is characterized in that possessing:

  • The car test measurement unit that moves ahead, it detects the vehicle headway between this vehicle and the preceding driving;

    The accelerator operation amount detection unit, it detects the operational ton of accelerator;

    Accelerator operation antagonistic force arithmetic element, it is based on described detected vehicle headway, and computing makes the operation antagonistic force of described accelerator generation;

    Operation antagonistic force generation unit, it makes described accelerator produce the described operation antagonistic force that calculates;

    The travel conditions detecting unit, it detects the travel conditions of this vehicle;

    The driving torque determining unit, it determines the driving torque of this vehicle based on described detected accelerator operation amount;

    The drive source control unit, the output in its controlling and driving source is to export described definite driving torque;

    Accelerator reset operation detecting unit, it detects the reset operation of described accelerator;

    AndCorrecting unit, it is based on the travel conditions of described detected vehicle, with the driving torque of described vehicle characteristic with respect to described accelerator operation amount, proofreading and correct from the 1st propulsive effort/accelerator operation relation is the 2nd propulsive effort/accelerator operation relation, concerning in the driving process with described the 2nd propulsive effort/accelerator operation simultaneously, if detect the reset operation of described accelerator, then revert to described the 1st propulsive effort/accelerator operation relation.
