发明名称 METHOD AND CIRCUIT ARRANGEMENT FOR MONITORING A ROTATIONAL ANGLE SENSOR
摘要 <p>The invention relates to a monitoring method in which two variables of angle-dependent, amplitude-modulated carrier frequency signals are emitted on orthogonal windings (12a, 12b) of the rotational angle sensor and an evaluation is carried out by an input amplifier (V2, 11) which emits an output signal that is essentially zero when the signals of the variables are gene-rated according to functional usage. Alternately, an interference signal is generated at one-second intervals in both windings (12a, 12b) of the rotational angle sensor, the result of which is being evaluated and monitored by means of an input amplifier (V2, 11). An interference display signal is generated at the output of the input amplifier (V2, 11), said interference display signal being not equal to zero if no error or interruption is present in the system and equal to zero if an error or interruption is present in the system.</p>
