摘要： A vehicle power supply system includes a power source control device (88) that executes a process of switching a connection state of a driving circuit (61a) to the main power source (45) and an auxiliary power source (81) including; a process of switching the connection state so as to transition to a backup state as a voltage decrease of the main power source (45) occurs, and a process of switching the connection state so as to transition to a normal state as the voltage decrease of the main power source (45) is resolved. After a voltage decrease of the main power source (45) occurs, a turning-side control device (60) of a steering control unit (1) sets an output-limited state for a turning-side motor (32). The output-limited state is canceled upon the power source control device (88) completing switching of the connection state so as to transition.

摘要： A motor system includes a stator and a rotor situated to rotate relative to the stator. A plurality of phase windings are situated in the stator with a power circuit connected to the phase windings. A controller is configured to output control signals to the power circuit to selectively energize the phase windings to cause the rotor to rotate relative to the stator. A neutral switch circuit is connected between the phase windings and a neutral node and is configured to selectively disconnect the phase windings from the neutral node.

摘要： A motor controller (30) includes control systems (31, 32) that control actuation of a motor (20). Each control system (31, 32) includes a drive circuit (311, 321) and a calculation unit (310, 320). The calculation unit (310, 320) of each control system (31, 32) is connected to an independent rotation angle sensor (52, 53). The calculation units (310, 320) include master (310) and slave (320) calculation units. The master and slave calculation units (310, 320) control actuation of the corresponding drive circuit (311, 321) based on a current instruction value calculated by the master calculation unit (310) and a detection result of the rotation angle sensor (52) connected to the master calculation unit (310). When the detection result of the rotation angle sensor (52) connected to the master calculation unit (310) is abnormal, the master and slave calculation units (310, 320) each use a detection result of the rotation angle sensor (53) connected to the slave calculation unit (320) to control the actuation of the corresponding drive circuit (311, 321).

摘要： There is provided an electric power steering device which, when an abnormality occurs in one phase of a three-phase brushless motor, permits continuous driving of the motor using the remaining two phases without deteriorating the steering feeling. When a power distribution abnormality of a drive system of one phase of respective phase coils has been detected by an abnormality detection section 27, an abnormal-time phase current instruction value for using the remaining two phase coils is calculated based on a steering assist electric current instruction value Iref, and an electric motor 12 is driven based on that abnormal-time phase current instruction value. At that time, when an electrical angle ¸e falls within an acceleration region, the abnormal-time phase current instruction value is increased or decreased for correction, so as for the rotation of the three-phase brushless motor 12 to be accelerated in a steering direction.

摘要： An electric power steering device (100) includes an electric motor (10) configured to selectively perform steering assistance based on a detection result of a torque sensor (12) and automatic steering based on information outside a vehicle, a breakdown determination unit (32) configured to determine the breakdown of the torque sensor (12), and an intervention determination unit (33) configured to determine a steering intervention operation by the driver when the torque sensor (12) breaks down during the automatic steering. The automatic steering is released when the intervention determination unit (33) determines that the steering intervention operation has been performed.
