The present invention relates to a vehicle low acceleration estimation system, and a control method thereof. The vehicle low acceleration estimation system comprises: a step of estimating first acceleration through a pulse signal generated in a wheel sensor when the driving speed of a vehicle is not less than 6 KPH; a step of estimating second acceleration using an average value of the cumulative pulse signal when the driving speed of the vehicle is not more than 6 KPH; a step of updating or storing a biased initial value of a longitudinal acceleration sensor in accordance with a deviation change to compute a gradient of a slope; and a step of re-estimating the first acceleration through the gradient of the slope. |
