PROBLEM TO BE SOLVED: To optimize the occurrence estimation of snow fade while considering that, when a degree of a reduction in the deceleration of wheel rotation to execute snow fade cancellation control is set to be lower, snow fade is cancelled in a low grade but the occurrence estimation probability of the snow fade is reduced to impair the operating stability of a braking device, and when a degree of a reduction in the deceleration of wheel rotation to execute the control is set to be higher, the occurrence estimation probability of the snow fade is increased but a degree of temporary reduction of braking force due to the snow fade is higher to impair braking capability. SOLUTION: Snow fade cancellation control is performed after confirming the fact that the condition that the deceleration of wheel rotation leads to the occurrence estimation of snow fade is continued for a predetermined time.
