PROBLEM TO BE SOLVED: To prevent an erroneous estimate of a road surfaceμestimate on a wet road and improve estimate accuracy of a road surfaceμ. SOLUTION: In this antiskid controller constituted such that antiskid control is changed by a low friction coefficient road surface and a non-low friction coefficient road surface in accordance with the results of estimate by a road surface friction coefficient estimate means when a control unit 12 performs antiskid control, the road surface friction coefficient estimate means cancels low friction coefficient road surface judgement and performs return acceleration judgement for judging that a road surface is the non-low friction coefficient road surface if wheel acceleration exceedsμjudgement acceleration set in advance based on wheel acceleration after determining that the road surface is the low friction coefficient road surface based on pressure reduction time.
