  • Publication number: 20230278435
    Abstract: An electrified vehicle includes a motor, a clutch, a transmission, a rotational speed sensor configured to detect a rotational speed of the motor, and a control circuit configured to control the motor. The control circuit performs: a learning process of detecting a change in the rotational speed of the motor by the rotational speed sensor when the shift change is performed; and a control process of controlling the rotational speed of the motor based on the change in the rotational speed detected in the learning process, when the shift change is performed after the learning process.

  • Patent number: 11511811
    Abstract: A vehicle frame structure has a front side member that extends forward from a dashwall. An engine cradle is attached to the front side member with a lateral side portion of the engine cradle being located beneath and spaced apart from a lower surface of the front side member. An engine installed to the engine cradle with a portion of the engine extending upward from the engine cradle adjacent to an inboard surface of the front side member, A push-off structure is attached to an outboard surface of the front side member adjacent to a front end surface of the front side member. A portion of the push-off structure extends outboard from the outboard surface. Another portion of the push-off structure extends downward below the lower surface of the front side member toward the lateral portion of the engine cradle and the engine.

  • Patent number: 8730001
    Abstract: Provided is a reactor and a reactor component that can prevent cracking of a resin portion that is interposed between a coil and an internal core portion. The reactor includes a coil 10 and a core that includes an internal core portion 22 and a couple core portion 24. The coil 10 is formed by helically winding a wire. The internal core portion 22 is disposed inside the coil and forms a part of a closed magnetic path. The couple core portion 24 is joined to the internal core portion 22 and forms the remaining part of the closed magnetic path. The reactor includes a resin portion (internal resin portion 30) including a region that is interposed between the coil 10 and the internal core portion 22, and a cushioning member 70 that is interposed between the resin portion and the internal core portion 22 and that does not cover the couple core portion 24. It is preferable that the material of the cushioning member 70 has a Young's modulus that is smaller than a resin material of the resin portion.

  • Patent number: 8279035
    Abstract: A compact reactor with excellent productivity and heat dissipation is provided. Reactor 1? includes a coil formed by spirally winding a wire 2w and a magnetic core 3 having an inside core portion inserted into the coil and an outside core portion 32 coupled to the inside core portion. These core portions form a closed magnetic circuit. The coil is covered with an inside resin portion 4 on the outer circumference thereof to form a coil molded unit 20? with its shape being held. The outer circumference of a combination unit 10 of the coil molded unit 20? and the magnetic core 3 is covered with an outside resin portion 5?. Reactor 1? does not have a case and is thus compact. A surface of the outside core portion 32 on the installation side (core installation surface 32d) is exposed form the outside resin portion 5? and is in direct contact with a fixed object, thereby achieving excellent heat dissipation.
