  • Publication number: 20230311672
    Abstract: A control device for an electric vehicle is provided, which includes a drive motor of which magnetic poles of a rotor are comprised of variable magnetism magnets, and a clutch disposed between the drive motor and driving wheels. When the electric vehicle travels, the control device performs a torque control, and a first clutch control in which an engaging torque of the clutch is controlled to be higher than a demanded torque. When performing a magnetization control when the electric vehicle travels, the control device changes the clutch control from the first clutch control to a second clutch control in which the engaging torque is made to coincide with the demanded torque, before the execution of the magnetization control, and adds a given slip torque to the demanded torque to start a micro slip control in which the clutch is transitioned from an engaged state into a micro slip state.

  • Publication number: 20210107335
    Abstract: There is provided a passenger compartment structure that can save power while ensuring thermal comfort of an occupant. The passenger compartment structure allows control of thermal comfort of the occupant in a posture seated on a seat. The passenger compartment structure includes a layered structure constituting at least part of an interior member disposed at a position where the interior member is able to face a lower leg of the occupant. The layered structure disposed in each of a front middle portion, a front lower portion, a frontal lower portion, and a right surface front upper portion having a high geometric factor for the lower leg includes a surface layer, a structural parent layer, and a temperature control mechanism layer interposed between the surface layer and the structural parent layer.

  • Publication number: 20200406708
    Abstract: A vehicle compartment temperature control device includes: a first interior member including a temperature control mechanism layer that can adjust the temperature of a leg of the occupant in a first region, that is, a front portion and the like. The vehicle compartment temperature control device also includes a second interior member disposed above the first interior member and including a temperature control mechanism layer in a second region, that is, a steering and the like that can adjust the temperature of a part above the leg and is different from the temperature control mechanism layer in the first region. The vehicle compartment temperature control device also includes an ECU. The ECU performs control such that the temperature of the temperature control mechanism layer in the first region is higher than the temperature of the temperature control mechanism layer in the second region.
