摘要： In a motor control unit able to accurately detect a current-carrying failure without adding a motor rotation angular velocity to determination conditions, a current-carrying failure detection unit (71) determines whether a first determination condition that a phase current value is smaller than or equal to a predetermined current value, a power supply voltage (Vps) is higher than or equal to a predetermined voltage value, and a duty command value is continuously larger than or equal to an upper limit of a predetermined range corresponding to the predetermined current value is satisfied, determines whether a second determination condition that the phase current value is smaller than or equal to the predetermined current value, the power supply voltage (Vps) is higher than or equal to the predetermined voltage value, and the duty command value is continuously smaller than or equal to a lower limit of the predetermined range is satisfied. The current-carrying failure detection unit (71) 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 (71) determines that a current-carrying failure has occurred.

摘要： A motor control unit (15) supplies three-phase alternating currents to a motor (11) by controlling switching of pairs of transistors (T1 to T6) of an inverter circuit (20). Values of the phase currents that are supplied to the motor (11) are detected by current sensors (30u, 30v, 30w). When it is determined that a through-current has occurred in the transistors (T1 to T6) on the basis of the detected phase current values, driving of the inverter circuit (20) is stopped. A first threshold is set for the phase current values, and a second threshold is set for the sum of the phase current values. It is determined that a through-current has occurred in the transistors (T1 to T6) when at least one of the absolute values of the phase current values is larger than or equal to the first threshold and the absolute value of the sum of the phase current values is larger than or equal to the second threshold.
