Abstract: A monitoring and protecting circuit for an electronic antiskid braking system of a vehicle having a plurality of wheels, each wheel having a speed sensor unit providing a direct-current speed signal representative of the rotational speed of this wheel. The circuit includes means for selecting the speed signal having the higher level, apparatus for selecting the speed signal having the lowest level and apparatus for comparing these levels. The output of the comparing apparatus is transmitted through time-delay apparatus to a switching device controllable for inhibiting the operation of the antiskid braking system, whereby this system is inhibited when the comparing apparatus delivers an output for a time duration exceeding a predetermined amount. Apparatus are provided for preventing the inhibition of the antiskid braking system when the brakes of the vehicle are being applied, and when the discrepancies between the rotational velocities of the wheels are due to skidding during acceleration of the vehicle above a predetermined rate.
