  • Patent number: 10562522
    Abstract: A control apparatus for a power transmitting system of a vehicle includes a drive mode control portion for selectively establishing one of first and second engine-braking drive modes in which a braking torque of the engine is applied to the vehicle. The first engine-braking drive mode is established in an engaged state of the first coupling device, while the second engine-braking drive mode is established in an engaged state of the second coupling device. The drive mode control portion switches the power transmitting system between the first and second engine-braking drive modes, such that the engine speed is held constant in the process of switching between the first and second engine-braking drive modes.

  • Patent number: 10436304
    Abstract: A tolerance ring is arranged between an output-side rotary shaft and a rotor shaft. For this reason, even when looseness in a spline fitting portion of the output-side rotary shaft and rotor shaft is not filled, both the output-side rotary shaft and the rotor shaft are held by the tolerance ring so as not to rattle. Therefore, it is possible to reduce tooth hammer noise that occurs in the spline fitting portion. An output-side rotary shaft has oil passages for supplying lubricating oil to a tolerance ring. Lubricating oil is forcibly supplied through these oil passages to an annular space in which a tolerance ring is accommodated.

  • Publication number: 20190299969
    Abstract: A hybrid vehicle with an engine and a rotary machine each coupled to a drive wheel in a power transmittable manner, comprises: an electronic control device that makes the rotary machine output a starting-time compensation torque to compensate a drop in a drive torque caused in a starting process of the engine in addition to a running torque when the engine is started while the vehicle is in a running state in which the drive torque is generated by the rotary machine and the engine is in a stopped state. The electronic control device starts the engine such that a starting-time inertia torque that is generated according to starting of the engine and causes the drop in the drive torque is made smaller when a torque margin of the rotary machine which is applied to the starting-time compensation torque is relatively small than when the torque margin is relatively large.
