Antilock brake controlling method

摘要

It is a subject of the present invention to prevent, in an antilock brake controlling method, inhibition of antilock brake control or issuance of a fault warning by a diagnosis as a fault during off road traveling and further simplify the antilock brake control during normal traveling. It is discriminated by an off road discrimination section whether or not the situation of the road surface is an off road (ST02), and based on the discrimination, antilock brake control is changed over by an antilock control method changeover section between a normal traveling antilock brake control mode (ST03) for traveling on a road surface having a high coefficient of friction such as a pavement and an off road traveling antilock control mode (ST04) for traveling on a road surface having comparatively great roughness and having a low coefficient of friction such as a gravel road.
