The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An electric power steering apparatus comprising:
a steering assist section that applies assist force to a steering system to assist operation of a steering member, wherein the steering assist section is actuated by a drive source, the drive source being a motor;
a steering torque sensor that detects steering torque input to the steering system;
an abnormality detecting section that detects an abnormality in the steering torque sensor;
a steering angle sensor that detects a steering angle of the steering member;
a rotational angle sensor that detects a rotational angle of the motor; and
a control section that controls supply of drive power to the motor,
wherein, when the abnormality detection section detects an abnormality in the steering torque sensor, the control section controls the supply of drive power to the motor such that a converted steering angle, which is obtained by converting the rotational angle of the motor detected by the rotational angle sensor, follows a target steering angle, which is computed based on the steering angle detected by the steering angle sensor.
2. The apparatus according to claim 1, wherein the target steering angle is computed using phase lead compensation.
3. The apparatus according to claim 1, wherein the target steering angle is computed by subjecting a value based on the steering angle detected by the steering angle sensor to phase lead compensation.
4. The apparatus according to claim 1, wherein, when the abnormality detection section does not detect an abnormality in the steering torque sensor, the control section controls the supply of drive power to the motor such that the motor generates a motor torque that corresponds to a target value of the assist force, the target value being computed based on the steering torque detected by the steering torque sensor.
5. The apparatus according to claim 4, wherein the target steering angle is computed using phase lead compensation.
6. The apparatus according to claim 4, wherein the target steering angle is computed by subjecting a value based on the steering angle detected by the steering angle sensor to phase lead compensation.
