  • Publication number: 20240132045
    Abstract: The in-vehicle controller of the present disclosure is installed in a vehicle together an engine, a motor capable of generating electricity connected to a crankshaft of the engine, a high voltage battery connected to the motor by a high voltage power line, a low voltage battery, a DC/DC converter connected to the high voltage power line and a low voltage power line connected to the low voltage battery, and a relay attached to the high voltage battery side of the high voltage power line from the DC/DC converter. The in-vehicle controller of the present disclosure stops driving the DC/DC converter after driving off the motor when completing the batteryless driving by disconnecting the high voltage battery with the relay turned off.

  • Patent number: 11156196
    Abstract: A starting device is used in a starting system that includes a starting electric motor unit and a rotating electrical machine; the starting electric motor unit including a motor that rotates a pinion gear, and a pushing member that pushes out the pinion gear toward a ring gear, the ring gear rotating together with a crankshaft of an engine; the rotating electrical machine being connected to the crankshaft and rotating the crankshaft; the starting system being configured to push, using the pushing member, the pinion gear toward the ring gear, and drive the motor to rotate, based on driving force of the motor, the ring gear via the pinion gear, thus starting the engine. The starting device includes a drive instruction unit that instructs the rotating electrical machine to rotate the ring gear via the crankshaft during a pre-drive period before drive of the motor.

  • Publication number: 20200346312
    Abstract: A fixture includes a supporting body configured to support a front door panel (workpiece) in an inclined state, a pad capable of being abutted to a plate surface of the front door panel, and a negative-pressure unit serving to bring the plate surface of the front door panel into an attracted state by maintaining an inside of a space enclosed by the plate surface and the pad under negative pressure, while the pad is abutted to the plate surface of the front door panel. This negative-pressure unit can switch between a shutdown state in which an attracted state is not achieved, a weakly attracted state in which the attracted state is achieved with a relatively weak negative pressure, and a firmly attracted state in which the attracted state is achieved with a relatively strong negative pressure.

  • Publication number: 20200246856
    Abstract: A die includes a plastic positioning body configured to position a door outer panel to be set in a predetermined posture by being abutted along an edge of an edge of the door outer panel. This positioning body includes a metal inset (or metal inserts) having a higher surface hardness than the plastic at application portion (or portions) where force is applied from areas when these areas, in which deformation resistance at the door outer panel is locally increased, are bent back. The metal insert is in a half-embedded state in which one part of the metal insert(s) is exposed from a surface of the application portion while the remaining part is embedded inside the application portion.

  • Patent number: 8256161
    Abstract: An automatic opening/closing apparatus for vehicle including a detected subject and a detection sensor for detecting rotation of an output shaft is downsized. A worm gear mechanism decelerating a rotation speed of an electric motor to output it from the output shaft is accommodated in a gear case, and a drum is fixed to a tip portion of the output shaft projecting from the gear case to the outside, whereby motive power of the output shaft is transmitted from this drum to a sliding door. A concave portion centering at an axial center and recessed in an axial direction is formed in a worm wheel constituting the worm gear mechanism, a magnet unit constituting a rotation sensor is disposed inside the concave portion of the worm wheel, and a magnetic sensor for detecting rotation of the magnet unit is fixed to an inner surface of the gear case.
