  • Patent number: 11186284
    Abstract: A control device performs upshifting in a state in which an operating point of a rotating electrical machine for outputting requirement-based torque at wheel-based rotational speed falls within an operable range of the rotating electrical machine both before and after shifting a shift speed by the upshifting, and in which before shifting the shift speed, output torque from the rotating electrical machine is less than or equal to determination torque (T1), the wheel-based rotational speed being rotational speed of the rotating electrical machine based on rotational speed (V) of a wheel, the requirement-based torque being output torque from the rotating electrical machine based on required wheel transmission torque, and the determination torque (T1) being torque obtained by subtracting an amount of increased torque (?Tmg) resulting from torque increase control from maximum torque (Tmax) that can be outputted from the rotating electrical machine at the wheel-based rotational speed.

  • Patent number: 11187318
    Abstract: A vehicle includes an engine; a continuously variable transmission; an output clutch disposed between the continuously variable transmission and the drive wheel; a drive motor coupled between the output clutch and the drive wheel; a traveling mode controller; and a speed ratio controller. In a case where required driving power based on an accelerator position is less than a first threshold, the traveling mode controller switches a traveling mode to a first traveling mode. In a case where the required driving power is equal to or greater than the first threshold, the traveling mode controller switches the traveling mode to a second traveling mode. In a case where the required driving power is less than the first threshold and equal to or greater than a second threshold, the speed ratio controller causes a speed ratio of the continuously variable transmission to change depending on a vehicle speed.
