  • Publication number: 20250249769
    Abstract: An electrified vehicle includes: a motor including three-phase coils connected to each other at a neutral point; a power storage device; an inverter connected to the power storage device and configured to drive the motor; and a control device configured to, during external charging in which electric power supplied from an external power supply to the neutral point is supplied to the power storage device along with voltage conversion, control each phase of the motor and the inverter by setting a duty command using feedback control to cancel out a difference between a phase current and a phase current command based on a current command at the neutral point. The control device is configured to, when the phase current is in a transient state during the external charging, larger value for a gain in the feedback control than when the phase current is not in the transient state.

  • Publication number: 20240278292
    Abstract: Provided is an ultrasonic shower cleaning device configured to apply an ultrasonic vibration to a cleaning liquid to perform cleaning. The ultrasonic shower cleaning device efficiently applies the ultrasonic vibration to the cleaning liquid flowing through a flow passage so as to allow the cleaning liquid to be ejected in a spot-like or linear fashion to an object to be cleaned without scattering the cleaning liquid. An ultrasonic shower cleaning device (1) includes: a vibrating body (20), which defines a part of the flow passage (48), and is configured to apply an ultrasonic vibration to the cleaning liquid; and a discharge port (47) configured to allow discharge of the cleaning liquid flowing from the flow passage. The vibrating body is provided so as to be continuous from an inside of the flow passage and project to an outside of the discharge port.

  • Publication number: 20230311567
    Abstract: The disclosure provides an automatic wheel configuring device that configures a wheel according to the inclination of a hub of a vehicle. The automatic wheel configuring device includes a detection device. The detection device takes an image of the hub or the wheel of the vehicle, and detects the positions of the hub bolts or the positions of the bolt holes of the wheel. The detection device includes an acquisition portion and a circle extraction portion. The acquisition portion acquires basic position information on the positions of the hub bolts or the positions of the bolt holes of the wheel. The circle extraction portion extracts a plurality of circles present in the captured image. Among the combinations of a plurality of circles, the circle extraction portion extracts a combination that matches the basic position information as a combination of hub bolts or a combination of bolt holes.
