A skid control system is provided for use with a vehicle having at least first and second spaced apart, independently rotatable wheels and having a braking system for applying braking forces to the wheels. A brake control device responds to an applied skid signal for controlling the braking system to release the braking forces on the wheels. A first logic circuit provides a skid signal when a predetermined percentage of the magnitude of a high wheel speed signal, representative of the faster of the two wheels, differs from that of a low wheel speed signal. A second logic circuit provides a skid signal when the greater of an average wheel deceleration signal, representative of the average deceleration of the two wheels, and a high wheel deceleration signal, representative of the deceleration of the faster wheel, is greater than a reference. An adaptive time delay circuit delays application of a skid signal to the brake control system for a time duration which varies in dependence upon the deceleration of the faster of the two wheels. A third logic circuit provides a skid signal when the acceleration of the faster wheel exceeds a reference acceleration level. An enabling circuit passes this skid signal only if another logic circuit has provided a skid signal. |
