Antilock control method

Abstract

An antilock control method wherein during the running of an automotive vehicle on a road surface (μ-split surface) having a different coefficient of friction where one of the right and left wheels of the same axle is on a road surface of the higher coefficient of friction and the other one of the wheels is on a road surface of the lower coefficient of friction, when the brake is operated and an antilock control starts, the wheel that runs on the road surface having the lower coefficient of friction excessively slips in a first cycle of the antilock control, and a predetermined condition is satisfied, 1) a hydraulic braking pressure to the wheel that runs on the road surface having the higher coefficient of friction is progressively decreased during progressively decreasing periods of time, and 2) after the pressure decreasing, another predetermined condition is satisfied, a gentle increasing of the hydraulic braking pressure to the wheel that runs on the road surface having the higher coefficient of friction starts, whereby the road surface having the higher coefficient of friction is efficiently utilized, thereby eliminating insufficient deceleration of the vehicle body.
