Abstract: When a shaft misalignment detection part detects occurrence of a shaft misalignment that is a misalignment in a relative position in a radial direction of a rotary shaft between a magnet part and a sensor part, the shaft misalignment detection part outputs a shaft misalignment determination flag to a correction part and a control change instruction part. The correction part calculates a motor rotational angle so as to reduce a detection error caused by the shaft misalignment. The control change instruction part outputs instructions of changing calculation methods so that influence by the detection error decreases to an assist torque setting part and an assist current instruction part.

Abstract: A microcomputer calculates an internal resistance value of a motor, and subsequently calculates an internal resistance value of a switching element of a motor drive circuit. When the internal resistance value of the motor is a semi-abnormal value, the microcomputer sets an upper limit current. When the internal resistance value of the motor drive circuit is a semi-abnormal value, the microcomputer sets an upper limit current. The microcomputer sets a smaller one of the upper limit current and the upper limit current as an upper limit current of the motor. In this manner, the progress of degradation of the motor and the motor drive circuit can be suppressed.

Abstract: An electrical angle estimation section calculates an estimative electrical angle on the basis of an inductive voltage generated in a motor, and obtains an estimative electrical angle by correcting the estimative electrical angle by an electrical angle correction amount. On the basis of a detection value which represents the difference in electrical angle between the q-axis and the ?-axis calculated by an electrical-angle-error detection section, an electrical-angle-correction-amount computation section calculates an electrical angle correction amount such that the electrical angle of the ?-axis falls within a prescribed angular range, which lags behind the q-axis in terms of electrical angle. Thus, when sensorless control is performed, a phenomenon in which the motor loses synchronism can be restrained.

Abstract: During a non-control mode, a separation valve is closed, and thus separates a first supply path that supplies working fluid to at least one of wheel cylinders and a second supply path that supplies working fluid to at least one of the other wheel cylinders, from each other. An on-off valve provided on the first supply path is kept closed despite a valve opening command, due to the effect of the differential pressure between the outlet and inlet openings of the valve if the differential pressure is above a predetermined value while the valve is closed. When occurrence of a closure failure on the separation valve is assumed during braking, a brake ECU stops the control performed by a wheel cylinder pressure control system, and shifts to a backup non-control mode, and controls the discharge of working fluid from the first supply path-side wheel cylinders so that the on-off valve is opened in accordance with the valve opening command. Thus, the confinement of the wheel cylinder pressure is prevented.
