PROBLEM TO BE SOLVED: To change correction of uphill slope distribution offset value of a G sensor output newly to prepare accurate estimated body speed by providing an operational means for operating and correcting G sensor output error caused by a road slope rate when the road slope rate is determined to be changed. SOLUTION: In an antiskid control device, when braking force is not acted and body speed equals to wheel speed at traveling on an uphill, normal traveling without wheel slip is determined and an output error of a vehicle acceleration detecting means (a) by a G sensor is corrected by a G sensor zero point correcting means (c). And change of a value of the G sensor at wheel slip control and change of control liquid pressure are change in road slope rate from wheel speed and roadμchange are determined by a change rate determination means (d) and when the change of the road slope rate is determined by the change rate determination means (d), the G sensor output error caused from road slope is operated and corrected by the G sensor zero point correcting means (e).
