An antilock braking system using stress sensors installed in the wheel axle of a motor vehicle. The stress sensors measure a road surface frictional force, a vertical load, a road surface friction coefficient, a braking torque, and a side force. An arithmetic calculator calculates a parameter value M from these measured values. An ABS controller controls movement process toward a braking pressure reduction mode in accordance with the change in the value M. Thereby, the system can preclude the locking of the wheel of the motor vehicle even when the brake is suddenly applied.

[ What is claimed is:] [1.] A control method for controlling the release timing of the brake pressure in antilock braking systems for motor vehicles by processing a measured value of at least one stress sensor in an arithmetic means, said method comprising the steps of:sampling a measured value Fs of road surface frictional force between a road surface and a wheel of the motor vehicle, a measured value Ts of braking torque applied on the wheel from the stress sensor respectively;calculating a parameter M=Fs-Ts from said sampled value; andmonitoring a calculated value of said parameter M from the time when a braking pressure is applied on the wheels to release the braking pressure when the calculated value of said parameter M reaches a prepared threshold TH.
