An ECU, which is a signal control apparatus, has a plurality of control units, which control one same motor. Steering angle calculation units acquire sensor signals from the angle sensors provided corresponding to the steering angle calculation units, respectively, and calculate the steering angles in correspondence to the sensor signals. The angle FB units perform the angle FB control based on the angle differences, which are between the target angle and the steering angle and between the target angle and the steering angle, respectively. In the angular FB unit of at least one of the control units, the angular feedback control is performed using the angle difference, which is subjected to the correction processing to reduce the error between the detection angle of the own system and the detection angle of the other system calculated by the steering angle calculation unit of the other control unit.

Each of a plurality of microcomputers outputs a motor drive signal, which is generated based on a current command value and a current limit value as a control amount command value and a control amount limit value, to each motor drive circuit. When an OFF determination of an own microcomputer is made, each microcomputer executes first end processing as a first stage of end processing and transmits an OFF determination signal to the other microcomputer. When the OFF determination signal is received from the other microcomputer, each microcomputer determines that the OFF determination has been made and starts second end processing which gradually decreases the current command value or the current control limit value from a present value. When the second end processing is completed and power-off preparation of the own microcomputer and the other microcomputer is completed, each microcomputer executes final end processing for turning off the power supply relay.
