摘要： An electrical load is supplied with power from a driving power source, and a microprocessor (CPU) controls the opening/closing current supply rate (duty factor) of an opening/closing element in accordance with target current and driving power source voltage so that open loop control is carried out to achieve predetermined target current. The voltage between both the ends of a current detecting resistor connected to the ground side of the opening/closing element is input as a monitoring voltage from a current detecting amplifying circuit portion through a multichannel AD converter to CPU. When the error between the comparison target voltage corresponding to the target current and the monitoring voltage is above a first permissible error, CPU judges that there is an abnormality sign, and if the error is above a larger second permissible error, CPU judges that there is appearing abnormality. Accordingly, an abnormality sign of a semi-wire-breaking/semi-short-circuit state of the electrical load can be sensed, and abnormality notification can be carried out.

摘要： A power steering apparatus for an automobile or other vehicle has a steering shaft constituted by an input section and an output section connected by a torsion bar. A mechanism for detecting when a driver is imparting torque to the steering wheel of the vehicle is constituted by a potentiometer having a resistive element and a wiper arm, one of which is mounted on the output section and the other of which is mounted on the torsion bar so that the wiper arm will rotate with respect to the resistive element and the resistance of the potentiometer will change when the torsion bar is rotated with respect to the output section. The potentiometer is electrically connected to a preamplifier mounted on the steering shaft, and the preamplifier is electrically connected to slip rings through which its output can be supplied to a stationary control unit. The electrical output of the potentiometer is independent of the speed of rotation of the steering wheel.
