Abstract: A vehicle fuel economy system and method of operating same includes vehicle sensors for measuring fuel economy data about a vehicle. The fuel economy data includes an actual mileage and an actual fuel consumed of the vehicle. The vehicle fuel economy system includes a display device for displaying the fuel economy data, and a control device operatively connected for computer communication to the vehicle sensors and the display device. The control device, upon determining the actual mileage is below or equal to a predetermined mileage threshold, calculates an initial average fuel economy by adjusting the actual mileage by the predetermined mileage threshold. Also, the control device, upon determining the actual mileage is above the predetermined mileage threshold, calculates an average fuel economy based the actual mileage and the actual fuel consumed. The control device controls the display device to display the initial average fuel economy or the average fuel economy.

Abstract: A system can control an engine during a shift event of a multi-ratio transmission driven by the engine. The engine can include a throttle valve configured to selectively regulate a flow rate of air entering the engine. The system can include a controller configured to receive shift data indicative of an execution of the shift event by the multi-ratio transmission, receive first sensor data indicative of a temperature of the engine and second sensor data indicative of a temperature of the multi-ratio transmission, obtain a transient air value based on the temperature of the engine and the temperature of the multi-ratio 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.
