  • Patent number: 11453295
    Abstract: A control system for a vehicle to prevent a reduction in a drive force due to increase in an internal resistance of a battery. A controller calculates a command value of an output power of the battery to be transmitted to a motor in future, and predicts an internal resistance of the battery at the point to discharge the electric power from the battery in the amount of the command value. If it is expected that the battery will not be possible to discharge the electric power in the amount of the command value, the controller reduces a load on the battery by increasing an amount of the electric power supplied to the motor from the generator before the battery can no longer discharge the electric power in the amount of the command value.

  • Publication number: 20220080949
    Abstract: A hybrid vehicle includes: a power generation device including an engine, a first rotating electric machine, and a first inverter; a drive device including a second rotating electric machine that outputs driving force, and a second inverter; an electric storage device that exchanges electric power with the power generation device and the drive device; a switching device that switches electrical connection of the electric storage device and the power generation device between parallel connection and series connection; and a control device that at least controls the switching device. Further, the control device controls the switching device in such a manner as to switch the electric storage device and the power generation device from the parallel connection to the series connection in a case where a combination of a vehicle speed and driving force satisfies a predetermined condition while the hybrid vehicle is traveling.

  • Patent number: 10527096
    Abstract: A rolling bearing includes an inner ring, an outer ring, a plurality of balls, and an annular cage that holds the balls at intervals in a circumferential direction. The cage has an annular portion on a first side in an axial direction, and a plurality of cage bars. Pockets that hold the respective balls are each formed between a pair of the cage bars adjacent to each other in the circumferential direction on a second side in the axial direction with respect to the annular portion. Each of the pockets has a pocket surface shaped along a cylindrical surface centered around a center line that is a virtual line extending in a bearing radial direction. A linear protrusion that is elongate in a direction parallel to the center line is provided at an axially-first-side bottom portion of the pocket surface.

  • Patent number: 10253813
    Abstract: An inner ring includes: a pair of shoulder outer peripheral surfaces on first and second axial sides of a raceway surface of the inner ring in contact with balls; seal grooves disposed in first and second axial ends of the inner ring and defining labyrinth clearances with lips; and edges disposed on the first and second axial sides. Each of the edges is configured to cause grease flowing along an associated one of the shoulder outer peripheral surfaces to leave the shoulder outer peripheral surface in the direction of an extension thereof. Each of the lips includes a lip oblique surface functioning as a guide surface to guide the grease that has left the edge not to a radially inner region of the bearing but to a radially outer region of the bearing.
