A steering control apparatus of a simple configuration is adaptable so A steering control apparatus of a simple configuration is adaptable so as to construct a redundant system from an input to an output system at low cost in a reliable manner. A torque sensor detects a steering torque, and a motor ( 3 ) provides torque to a steering system. A motor drive circuit ( 56 ) drives the motor, and a steering control section ( 53 a) calculates at least a target current for the motor based on the steering torque. A motor control section ( 53 b) provides an instruction to the motor drive circuit ( 56 ) based on the target current. A steering control verification section ( 54 a) verifies an operation of the steering control section ( 53 a) based on the steering torque and the target current. A motor control verification section ( 54 b) verifies an operation of the motor control section ( 53 b) based on a predetermined state quantity of the motor drive circuit ( 56 ) or the motor ( 3 ). |
