1. vehicle headway maintenance assisting device has:

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

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

    Accelerator operation antagonistic force arithmetic element, it is according to the aforementioned vehicle headway that is detected by the aforementioned car test measurement unit that moves ahead, and computing makes the operation antagonistic force of aforementioned accelerator generation;

    Operation antagonistic force generation unit, it makes aforementioned accelerator produce the operation antagonistic force that is calculated by aforementioned accelerator operation antagonistic force arithmetic element;

    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 according to the operational ton by the detected aforementioned accelerator of aforementioned accelerator operation amount detection unit;

    The drive source control unit, the output of its control drive source is to export the driving torque of being determined by aforementioned driving torque determining unit;

    AndCorrecting unit, it is according to the testing result of aforementioned travel conditions detecting unit, relation between the operational ton of the aforementioned accelerator that correction is determined by aforementioned driving torque determining unit and the driving torque of aforementioned vehicle is so that the easy aforementioned accelerator operation antagonistic force of identification of driverIt is characterized in that, the aforementioned corrected unit is according to the testing result of aforementioned travel conditions detecting unit, proofread and correct the relation between aforementioned accelerator operation amount and aforementioned driving torque, to reduce the aforementioned driving torque corresponding with aforementioned accelerator operation amount, and, after carrying out aforementioned corrected, the driving torque of aforementioned vehicle increases along with the increase of aforementioned accelerator operation amount.
