  • Publication number: 20240141154
    Abstract: A crosslinked rubber composition includes: a rubber component containing a first polymer which is an ethylene-?-olefin elastomer having an ethylene content of less than 60% by mass and a second polymer which is an ethylene-?-olefin elastomer having an ethylene content of 60% by mass or more; and short fibers dispersed in the rubber component. The rubber component is crosslinked by using organic peroxide as a crosslinking agent. The content of the organic peroxide in a not-yet crosslinked rubber composition is 1 part by mass or more and 10 parts by mass or less relative to 100 parts by mass of the rubber component.

  • Patent number: 11951990
    Abstract: A gear shift control device of an automobile including a driving motor, a relay clutch capable of disconnecting an engine, includes memory storing a gear shift map for determining the switching start timing of the gear position, a transmission control unit that switches the gear position based on the gear shift map, a regeneration control unit, and a relay clutch control unit. The gear shift map includes a cooperative regeneration map and non-cooperative regeneration maps that define the thresholds of relatively low revolutions. The threshold of a predetermined low gear shift point is defined to be smaller than the thresholds of the gear shift points higher than the predetermined low gear shift point on the downshift side in the non-cooperative regeneration maps, and is defined to be smaller than the threshold of the predetermined low gear shift point on the downshift side in the cooperative regeneration map.
