  • ANTILOCK CONTROL METHOD
    Publication number: 20010050510
    Abstract: An antilock control method wherein during the running of an automotive vehicle on a road surface (&mgr;-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 every period while changing a forcible pressure-decreasing time, and 2) after the pressure decreasing, another predetermined condition is satisfied, a gentle decreasing of the hydraulic braking pressure to the wheel that runs on the road surface having the higher coef
