Claim:
1. A vehicle brake hydraulic controller including: an antilock braking controlling module configured to perform an antilock braking control in which a brake hydraulic pressure applied to wheel brakes is reduced under the condition that a slip-related amount has reached a pressure reduction threshold value, the slip-related amount being calculated using a vehicle speed and a wheel speed; and a turning judging module configured to judge whether a vehicle is turning based on a steering angle, wherein, when the antilock braking control is performed and in the case that the turning judging module judges that the vehicle is turning, the antilock braking controlling module performs a turning pressure reduction control so as to: a road surface friction coefficient judging module configured to judge whether a road surface on which the vehicle is running is at least a low friction coefficient road surface, and wherein the antilock braking controlling module performs the turning pressure reduction control only in the case that the road surface is judged to be the low friction coefficient road surface, and wherein the road surface friction coefficient judging module includes: wherein the selecting module has a limit steering judgment section configured to judge whether steering exceeding the limit of road surface conditions is performed based on at least the steering angle and the vehicle speed, and wherein the selecting module selects:
