摘要： An abnormality diagnosing method is provided for a torque detecting device and an electric power steering device is provided using the torque detecting device. Immediately after the power supply is turned on and before steering auxiliary control is started, initial diagnosis is performed to determine that each monitoring block for monitoring an abnormality of a signal processing circuit constituting a torque detecting device operates normally. The initial diagnosis determines that a monitoring block is operating normally, by inputting a normal signal and an abnormal signal to the monitoring block alternately, and finding that the monitoring block carries out normal diagnosis when it receives the normal signal and that it carries out abnormal diagnosis when it receives the abnormal signal. Once all of the monitoring blocks are determined as normal, the steering auxiliary control based on a steering torque detected by the torque detecting device is started.

摘要： There is provided a torque detecting device for providing a highly accurate torque signal, and an electric power steering device using the torque detecting device. A torque sensor is provided with a first coil pair and a second coil pair, which detect a relative displacement between an input shaft and an output shaft by corresponding the relative displacement to a change in impedance. Magnetization signal generating units supply exciting currents with different magnetization frequencies to the first coil pair and a second coil pair, respectively. The magnetization frequency difference is set to 3.5 kHz or higher. Moreover, low-pass filters for intercepting passage of a frequency equivalent to the magnetization frequency difference are deployed in signal processing circuits respectively.

摘要： An angle position detection apparatus according to the present invention includes: a unipolar resolver and a multipolar resolver installed so that reluctance is changed in synchronization with the revolution of a direct motor drive; and a select switch is used to switch between paths along which an excitation signal from a transmitter is supplied to these resolvers. When the supply path for the excitation signal is changed by the select switch, at the least, the unipolar resolver and the multipolar resolver are not excited at the same time, so that magnetic flux leaking from one resolver does not electrically interfere with the other resolver. Therefore, the unipolar resolver and the multipolar resolver 30 can be arranged so they are near each other, and the size and the thickness of the angle detection apparatus can be reduced.
