1. A drive force-limiting device for limiting a drive force that acts on a drive wheel of a vehicle, the drive force-limiting device comprising:

  • an acceleration correction unit for correcting a first acceleration of the vehicle and obtaining a corrected first acceleration as a second acceleration;

    a first calculation unit for calculating a first speed of the vehicle on the basis of a wheel speed of the drive wheel and the first acceleration;

    a second calculation unit for calculating a second speed of the vehicle on the basis of the wheel speed and the second acceleration;

    a request unit for requesting a limiting drive force for limiting the drive force in a case that a difference between the first speed and the second speed is equal to or greater than a first threshold value; and

    an estimation unit in which the second speed is used as an estimated speed of the vehicle, whereinthe request unit requests the limiting drive force, whereby, when the wheel speed is less than a second threshold value, the estimation unit resets the second speed using the first speed and obtains the estimated speed.
