  • Publication number: 20240123776
    Abstract: A tire assembly includes a tire for mounting on a vehicle, an elastic body disposed on an inner side of the tire, and a power generation body disposed between an inner surface of the tire and the elastic body. The power generation body includes a first member and a second member. The first member has a first insulating film forming a first surface. The second member has a second insulating film forming a second surface that faces the first surface and contacts the first surface. The elastic body biases the power generation body toward the inner surface of the tire.

  • Publication number: 20240059273
    Abstract: A control device is configured to perform torque response slip control for bringing an engagement device into a slip engaged state so that transfer torque of the engagement device has a magnitude corresponding to required torque, shift control for shifting the shift speed of an automatic transmission, and transfer torque limit control for limiting the transfer torque of the engagement device to a value equal to or less than a limit value smaller than the required torque, the required torque being torque that is required to be transferred from the rotating electrical machine side to the automatic transmission via the engagement device that connects and disconnects power transmission between the rotating electrical machine and the automatic transmission. The control device performs the transfer torque limit control instead of the torque response slip control in a case where the torque response slip control is being performed when performing the shift control.

  • Publication number: 20150128572
    Abstract: An exhaust gas control apparatus for an internal combustion engine, controls an exhaust operation of the internal combustion engine (200) provided with an exhaust gas purification catalyst (216) in an exhaust passage (215). The exhaust gas control apparatus for the internal combustion engine is provided with a warming-up device configured to warm up the exhaust gas purification catalyst; and an oxygen supplying device (220, 221) configured to supply oxygen to the exhaust gas purification catalyst after the end of the warm-up. This makes it possible to preferably desorb sulfur adsorbed to the exhaust gas purification catalyst during warm-up. It is therefore possible to suppress a reduction in purification ability of the exhaust gas purification catalyst due to sulfur coating.
