Abstract: FIELD: control of the vehicle driving force. 
     SUBSTANCE: group of inventions relates to a method and equipment for control of the vehicle driving force. The vehicle drive source is a motor mounted on the vehicle body through a rubber mounting (support) element. The mounting element is linearly compressed only when an external force, less than predetermined lower limit value of the external force, is applied to it. The mounting element is linearly compressed to create a force less than the limit value of the external force caused by a change in the driving force and deflects the drive source back to push the mounting element. In the first region, the driving force is equal to or exceeds a predetermined lower limit value, the rate of the driving force change per unit of time is limited to a predetermined maximum speed or lower. On the other side, in the second region, in which the driving force is less than the lower limit value, the rate of the driving force change per unit of time is not limited to the maximum speed or lower.  
     EFFECT: driving force control is achieved to reduce the noise from the vehicle.
