Claim 20:
21. A method for monitoring a drive belt, the method comprising:
providing a steering gear having first and second toothed belts of the drive belt arranged in parallel;
marking the first and second belts with a first marking of strips of polymeric materials with magnetizable particles applied over a belt width on back sides for the first and second belts;
sensing the first and second belts with first and second electronic devices to generate signals SR1 and SR2 for the first and second belts respectively;
detecting the passage of the first marking of the first and second belts based on the signals SR1 and SR2;
providing second markings on a rotor of a drive motor;
sensing the rotor with a third electronic device to generate a rotor signal SM;
detecting passage of the second markings based on the rotor signal SM;
determining a speed of the rotor based on the signal SM; and
determining an angular offset between the drive belt and the rotor by one or more processors based on the signals SR1, SR2 and SM.
