Abstract: A steering torque shift control amount calculation unit (31) calculates the steering torque shift control amount (?ts) by multiplying the basic shift amount (?ts_b) used as the basic compensation component by the transition coefficient (Kss). Then, the steering torque shift control amount (?ts) is subjected to the low-pass filter process in an abrupt change prevention processing unit (32). An abrupt change prevention processing unit (40) is provided in the steering torque shift control amount calculation unit (31). The transition coefficient (Kss) is subjected to the low-pass filter process in the abrupt change prevention processing unit (40). The cutoff frequency of the low-pass filter that forms the abrupt change prevention processing unit (40) is set to a value lower than the cutoff frequency of the low-pass filter that forms the abrupt change prevention processing unit (32) that executes the low-pass filter process on the torque shift control amount (?ts).

Abstract: In a motor control unit, a current-carrying failure detection unit determines a first determination condition and a second determination condition. The current-carrying failure detection unit measures a duration of a state where the first determination condition is satisfied, and a duration of a state where the second determination condition is satisfied. When the first or second duration exceeds a predetermined reference period, the current-carrying failure detection unit determines that a current-carrying failure has occurred.

Abstract: An electric power steering (EPS) apparatus 1 includes a motor 12, an EPS actuator 10, a torque sensor 14, and an ECU 11. The EPS actuator 10 uses the motor 12 as a drive source to apply assist force to a steering system, thereby assisting a steering operation. The torque sensor 14 detects a steering torque ? of the steering system. The ECU 11 controls the operation of the EPS actuator 10. Based on the steering torque ? detected by the torque sensor 14, the ECU 11 computes a basic shift amount ?ts_b of the assist force applied to the steering system. The ECU 11 determines which one of returning, holding, and turning is the state of the steering operation. When the state of the steering operation is returning or holding, the ECU 11 executes compensation control for correcting the steering torque ?, which is used in the computation of the basic shift amount ?ts_b of the assist force, thereby increasing the assist force applied to the steering system.

Abstract: A motor control signal output unit of an electric power steering system includes a feedback gain calculation unit (52), and a feedback control unit executes a feedback control with the use of a proportional gain (Kp) and an integral gain (Ki) that are calculated by the feedback gain calculation unit (52). The feedback gain calculation unit (52) sets the feedback gains to large values (Kp=P0, Ki=I0) when the absolute value of an assist gradient (?) is equal to or smaller than a predetermined value (?0) (|?|??0). On the other hand, when the absolute value of the assist gradient (?) exceeds the predetermined value (A) (|?|>?0), the feedback gain calculation unit (52) sets the feedback gains to small values (Kp=p1, Ki=I1:P1<P0, I1<I0).
