Einrichtung zum Erkennen des Schlupfs von Fahrzeugraedern

摘要

A slippage detecting system for use in conjunction with motor vehicles. Each wheel of the vehicle is provided with a transducer which supplies a voltage dependent upon the speed of the wheel. The transducer output is applied to a Schmitt-trigger circuit which becomes actuated when the voltage exceeds a predetermined value. Upon actuation of the Schmitt-trigger circuit, the braking system of the motor vehicle is operated through an amplifier, so that the braking force is regulated to prevent locking of the wheels. The transducer is in the form of a voltage generator with regulated excitation voltage. The voltage regulator includes an integrator and is connected between the output of the generator and the excitation winding thereof.
