Apparatus for controlling an engine during a shift event, powertrain including same, and method

A powertrain for a vehicle comprising:

• an internal combustion engine configured to output torque and including a throttle valve configured to selectively vary a flow rate of intake air that enters the internal combustion engine;
• a transmission driven by the internal combustion engine, the transmission includes a plurality of gear ratios configured to selectively multiply the torque output by the internal combustion engine, and the transmission is configured to execute a shift event from a current gear selection to a target gear selection where,
• the current gear selection is one of a plurality of gear selections,
• the target gear selection is a different one of the gear selections, and
• the plurality of gear selections includes a park selection and a plurality of ratio selections, and each of the ratio selections corresponds to a respective one of the gear ratios;
• and
• a controller configured to,
• receive shift data indicative of an execution of the shift event by the transmission,
• receive first sensor data indicative of a temperature of the engine and second sensor data indicative of a temperature of the transmission,
• obtain a transient air value based on the temperature of the engine and the temperature of the transmission when the controller has received the shift data, and
• signal the throttle valve to move to a position corresponding to the transient air value when the controller has received the shift data.
