  • Patent number: 11472473
    Abstract: A motor control device is provided with a plurality of power converters and a plurality of microcomputers, and controls driving of a motor that has a plurality of sets of windings. The microcomputers perform initial check of components in respective circuits after activation. The microcomputers prohibit driving of the motor by a circuit determined to be abnormal during the initial inspection. When two or more circuits are determined to be normal in the initial check, the microcomputers start driving of the motor by synchronizing the timing between the two or more circuits determined to be normal. When only one circuit is determined to be normal in the initial check, the microcomputers start driving of the motor by the one circuit determined to be normal.

  • Patent number: 11465683
    Abstract: A steering angle detection device is provided with a plurality of rotation angle sensors and a plurality of control units. The rotation angle sensors are capable of at least continuously calculating a rotation speed while an ignition switch of a vehicle is turned off, and are provided so as to correspond to steering angle calculation units which calculate steering angle based on the rotation speed and a rotation angle acquired from the rotation angle sensors and midpoint information related to the neutral position of a steering member. Power supplies are provided on a per-system basis. The rotation angle sensors or the control units are capable of holding the midpoint information while the ignition switch is turned off. If a power supply abnormality resulting in power supply failure occurs in some of the systems, the control unit of the abnormal system acquires the midpoint information and the rotation speed from the control unit of a normal system when the ignition switch is turned on.

  • Patent number: 11340277
    Abstract: An abnormality determination device for a secondary battery includes an internal-resistance calculation unit, a threshold memory unit, a capacity balance comparison unit, and an abnormality determination unit. The internal-resistance calculation unit detects an internal resistance in a negative-electrode reaction resistance dominant region in which a reaction resistance of a negative electrode is dominant in a charge and discharge reaction of the secondary battery. The threshold memory unit stores a capacity balance threshold used as a reference for determining abnormality in a balance between a capacity of a positive electrode and a capacity of the negative electrode in the secondary battery. The capacity balance comparison unit compares the internal resistance calculated by the internal-resistance calculation unit with the capacity balance threshold stored in the threshold memory unit.

  • Publication number: 20200112236
    Abstract: A laser welding method for a stator coil forms an abutting surface by abutting a side face of a first lead portion of a first rectangular wire to a side face of a second lead portion of a second rectangular wire. A laser beam is focused on a position more inward than a surface of an upper end of the abutting face between the first lead portion and the second lead portion, and the laser beam is moved in a helical loop on the upper end of the abutting face between the first lead portion and the second portion so as to melt the conductor wires to form a molten pool. The molten pool is then moved along the abutting face while the molten pool is continuously formed.
