Patent ID: 7222694

Claim:
A control unit for electric power steering, comprising: motor driving means for energizing an electric motor to operate a steering mechanism secondarily; motor current detecting means having an amplifier amplifying a voltage across a shunt resistor through which a motor current of said electric motor flows to output a current detection output indicating a value of said motor current; and control means for implementing control so that said current detection output obtained by said motor current detecting means reaches a target current value to said motor driving means determined on the basis of a steering torque in said steering mechanism; temperature detecting means for detecting a temperature of said motor current detecting means; and correction means for correcting the current detection output of said motor current detecting means on the basis of an output of said temperature detecting means; wherein said motor current detecting means is integrated in an integrated circuit package, and said temperature detecting means is integrated in said integrated circuit package so as to be situated in the vicinity of said amplifier of said motor current detecting means.
