Abstract: In a rotation angle detection device, when a condition that two sensors among three magnetic sensors sense one and the same magnetic pole for three consecutive sampling periods is satisfied, a rotation angle is computed based on output signals from the two sensors, sampled at three sampling timings. When the output signals sampled at the three sampling timings satisfy a prescribed requirement, an angular width error correction value corresponding to the magnetic pole sensed by the two sensors and amplitudes are computed, and stored in association with the magnetic pole. If the condition is not satisfied, the rotation angle is computed based on the information stored in a memory and the output signals from two sensors among the three magnetic sensors, the two magnetic sensors including one of the three magnetic sensors, which detects the magnetic pole of which the angular width error correction value is stored in the memory.

Abstract: In a phase difference detector, a first phase difference computation unit computes a value of E(i)·C corresponding to one and the same given magnetic pole sensed by the two magnetic sensors with use of six output signals sampled at three different timings while the two magnetic sensors are sensing the given magnetic pole when a rotary body is rotating. E is an angular width error correction value, and C is a phase difference between two signals. The first phase difference computation unit executes this process until values of E(i)·C corresponding to all the magnetic poles are computed. After that, the first phase difference computation unit computes the phase difference between the output signals with use of the values of E(i)·C corresponding to all the magnetic poles and the number (m) of the magnetic poles.

Abstract: Rotation angle computation modes include a normal mode and a simple mode. In normal mode, a rotation angle of an input shaft is computed based on output signals from first and second magnetic sensors, which are sampled at two sampling timings. In simple mode, the rotation angle of the input shaft is computed based on the output signals from the first and second magnetic sensors, which are sampled at one sampling timing, and an amplitude ratio between the output signals from the magnetic sensors set in advance. After a power supply is turned on, the rotation angle is computed in the simple mode until a condition that the rotation angle of the input shaft can be computed in the normal mode even if the immediately preceding value of the rotation angle of the input shaft is not present is satisfied. Then, the rotation angle is computed in the normal mode.

Abstract: Sinusoidal signals (S1, S2) having a phase difference of 120° are output from two magnetic sensors in accordance with rotation of an input shaft. A first rotation angle computation unit computes a rotation angle ?(n) on the basis of output signals S1(n), S1(n?1), S2(n), S2(n?1) from the magnetic sensors, which are sampled at two sampling timings. At this time, the first rotation angle computation unit computes the rotation angle ?(n) on the assumption that there are no variations of amplitudes of the output signals (S1, S2) from each one of the two sensors due to temperature changes between the two sampling timings.

Abstract: An output signal V1=sin ? is output from a first magnetic sensor and an output signal V2=cos(?+?) is output from a second magnetic sensor. An output signal correction unit in a rotation angle computing device corrects the output signal V2 from the second magnetic sensor to an output signal V2? (=cos ?) so that a positional phase difference (90°+?) between the magnetic sensors and is made equal to a target phase difference of 90°. A rotation angle computing unit computes the rotation angle ? of a rotor based on the corrected signal V2? (=cos ?) and the other output signal V1 (=sin ?).

Abstract: When the estimated motor temperature becomes equal to or higher than the first predetermined temperature, an addition angle correction unit temporarily decreases the absolute value of the addition angle output from an addition angle limiter at time intervals. The addition angle correction unit makes the time interval shorter as the estimated motor temperature increases. When the time interval becomes equal to or shorter than the predetermined threshold, that is, when the estimated motor temperature becomes equal to or higher than the second predetermined temperature that is higher than the first predetermined temperature, the addition angle correction unit notifies a command current value changing unit of a current stop command. Thus, the ?-axis command current value is changed to 0, and therefore the steering mode is shifted to the manual steer mode.

The motor controller includes an electric current driving unit which drives the motor with an axis electric current value defined in a rotating coordinate system defined with respect to a control angle that is a rotation angle for control, a control angle computing unit which computes a current value of the control angle by adding an addition angle to a previous value of the control angle in each predetermined computing cycle, and an addition angle computing unit which computes the addition angle according to a torque to be generated by the motor or a response of the motor to the axis electric current value.

Abstract: A motor control unit includes a detected steering torque correction unit that corrects the detected steering torque that is detected by a torque sensor and then subjected to a limitation process by a steering torque limiter. When the absolute value of the detected steering torque is equal to or smaller than a predetermined value, the detected steering torque correction unit corrects the detected steering torque to 0. When the absolute value of the detected steering torque is larger than the predetermined value, the detected steering torque correction unit outputs the detected steering torque without correction. A PI control unit calculates the addition angle based on the deviation of the control torque obtained through correction by the detected steering torque correction unit from the command steering torque.
