摘要： In a steering apparatus for a vehicle, a target sub steering angle θSREF is set by a target-sub-steering-angle setting unit on the basis of an output θH of a steering-wheel-angle detection unit and a transmission characteristic f(θH) of a transmission-characteristic setting unit, and a target current IREF is set by a target-current setting unit on the basis of the target sub steering angle θSREF and an output θS of the sub-steering-angle detection unit. Current control unit controls a current which flows through an electric motor of a sub-steering-angle superposition mechanism, so that the target current IREF and a current IS of current detection unit may agree.

摘要： A control device of a motor used in, for example, electric power steering control of a vehicle has to monitor the operation thereof to execute such a processing as stopping the control without delay upon detection of error. However, conventional monitoring devices have a disadvantage of taking a long time period the detection or not being able to detect an error of no output. A three-phase inverter circuit 52 having a substantially constant operation period is employed. The inverter 52 outputs an output waveform also at the moment of not driving the motor 2. An inverter period monitoring circuit 555 is provided to monitor a period of the output waveform. When the period comes to be too large or too small as compared with a carrier period of the inverter, an alarm is outputted, and control of the inverter is stopped.
