To provide a vehicle speed limiting device capable of suppressing the occurrence of a fade phenomenon.SOLUTION: A vehicle speed limiting device that imposes limits on a vehicle speed of a vehicle includes: a rotation speed measurement unit which measures the rotation speed of a drive source mounted on the vehicle; a weight measurement unit which measures the vehicle weight of the vehicle; a gradient information acquisition unit which acquires gradient information about the road surface gradient during travel of the vehicle; a deceleration torque measurement unit which measures the deceleration torque of the drive source; a vehicle speed measurement unit which measures the vehicle speed of the vehicle; and a vehicle speed limiting unit which limits the vehicle speed of the vehicle. The vehicle speed limiting unit controls the drive source so as to limit the vehicle speed if the deceleration energy of the vehicle calculated from the rotation speed of the drive source, vehicle weight, road surface gradient, deceleration torque, and vehicle speed is equal to or greater than a prescribed value.SELECTED DRAWING: Figure 1
