  • Patent number: 10710446
    Abstract: An engine starting system for starting an engine promptly during propulsion without reducing a drive force. When a condition to crank the engine is satisfied during propulsion in a neutral stage, torque is applied to an input rotary element to crank the engine by reducing a rotational speed of a control rotary element by increasing a torque capacity of a first engagement device to utilize an inertial force of the free rotary element as a reaction force.

  • Patent number: 10221799
    Abstract: A target air amount for achieving a requested torque is back-calculated from the requested torque using a virtual air-fuel ratio. The virtual air-fuel ratio is changed from a first air-fuel ratio to a second air-fuel ratio in response to a condition for switching an operation mode from operation in the first air-fuel ratio to operation in the second air-fuel ratio being satisfied. After the virtual air-fuel ratio is changed from the first air-fuel ratio to the second air-fuel ratio, an interval of time passes and the target air-fuel ratio is then switched from the first air-fuel ratio to a third air-fuel ratio that is an intermediate air-fuel ratio between the first air-fuel ratio and the second air-fuel ratio. The target air-fuel ratio is temporarily held at the third air-fuel ratio, and is thereafter switched from the third air-fuel ratio to the second air-fuel ratio.

After the virtual air-fuel ratio is changed from the first air-fuel ratio to the second air-fuel ratio, the target air-fuel ratio is changed in accordance with an air-fuel ratio efficiency within the range from the first air-fuel ratio to the second air-fuel ratio. The air-fuel ratio efficiency is calculated based on a proportion of the requested torque relative to a torque that can be achieved by means of a current estimated air amount under the theoretical air-fuel ratio and the optimal ignition timing.
