Abstract
A temperature information detecting device for an angle sensor is provided for detecting only temperature-dependent components based on middle-point potentials when a constant current is supplied to a bridge circuit for an angle sensor, for acquiring a temperature of the angle sensor from the temperature-dependent components, for employing compensating information corresponding to the acquired temperature without separately providing any additional temperature sensor, and for making temperature compensation of the output of the temperature sensor in automatically controlling the valve opening of a flow control valve.
