PURPOSE: A device for improving the driving force of a vehicle is provided to improve the driving force of a vehicle by minimizing the loss of power in a constant velocity joint used for a drive shaft. CONSTITUTION: A device for improving the driving force of a vehicle comprises a displacement sensor(1) installed to sense the contraction state of a shock absorber(106), an oil supply unit to control the contraction state of the shock absorber by supplying oil to the upper and lower parts of the shock absorber, and a controller(13) to control the oil supply unit by using a signal outputted from the displacement sensor. Since the contraction state of the shock absorber is controlled depending on the bending state of a constant velocity joint(112), the time for transmitting the rotational force is reduced. The loss of power is minimized by maintaining the linear state of a drive shaft(102).
