Abstract
A signal corresponding to the difference between wheel and vehicle speeds is generated when this difference exceeds a first predetermined value and this difference signal is stopped when the difference decreases below a second predetermined value. The difference signal is integrated linearly upwardly until the difference signal decreases to the second predetermined value at which point it is integrated linearly downwardly. An auxiliary signal is generated when the integrated signal is above a third predetermined value. An anti-locking signal is generated in response to the generated difference signal to release the vehicles brakes and this anti-locking signal is continued to be generated until both the difference signal and the auxiliary signal cease and at that point the brakes are again applied.
