  • Publication number: 20210074081
    Abstract: The invention provides a control unit and a control system for a vehicle capable of reducing a workload of deleting a record of information of an unintended event detected by a certain control unit by preventing the other control unit from recording the information of the event. Control units (50a to 50d) that are mounted on the vehicle and connected in a mutually communicable manner each include an event processing section (55). The event processing section (55) executes one or both of processing to switch whether to notify a recording request of the information of the event and processing to switch necessity/unnecessity of recording of the information of the event.

  • Patent number: 10724636
    Abstract: Provided is a combined oil ring that further reduces engine oil consumption. A combined oil ring attached to an oil ring groove of a piston includes: a pair of upper and lower side rails each formed into a flat annular shape, and having a slide contact part that comes into sliding contact with a cylinder; and a spacer expander arranged between the pair of upper and lower side rails. In at least the upper side rail of the pair of upper and lower side rails, a cross-sectional shape of the slide contact part along an axial direction of the piston is a tapered shape linearly spreading from upper to lower parts of the piston; the tapered shape is at an angle of 5 to 30 degrees with respect to a central axis of the spacer expander, and has a vertex of the tapered shape within 0.15 mm from a lower end of the side rail; and a part closer to the lower end than the vertex is formed into a curved shape having a curvature of R0.01 to 0.5.
