Abstract
An anti-lock brake control system for a motor in which influence of vibration of wheel driving shafts occurring upon braking in the state where the wheels (1a, 1b) are operatively connected to a prime mover such as an internal combustion engine is suppressed to thereby enhance the braking performance of the system. Rotation speed (Vw) of each of the driving wheels (1a to 1d) of the motor vehicle is detected for determining wheel acceleration (Gw). A torsion torque (Tt) applied to a wheel drive shaft is detected. The wheel acceleration (Gw) is corrected with the torsion torque (Tt) for determining a corrected acceleration (Gc). The brake application pressure is controlled in dependence on combinations of two variables, i.e., the corrected acceleration (Gc) and the wheel acceleration (Gw). Owing to detection of the torsion torque (Tt), not only the influence of the vibration of the wheel (1a to 1d) due to the torsion torque (Tt) but also a delay involved in the detection of the torsion torque (Tt) can be taken into consideration in the anti-lock brake control.
