Abstract
A vehicle includes an engine and a transmission coupled to the engine. A vehicle controller is programmed to, in response to a shift of the transmission with the vehicle being in a sport mode or other precondition being present, command the engine to skip one or more fuel injector events of the engine during an inertia phase of the shift.
Claims16
A vehicle comprising:
- an engine;
- a transmission coupled to the engine;
- and
- a controller programmed to, in response to a shift of the transmission with the vehicle being in a sport mode:
- retard spark of the engine to reduce torque of the engine to a target value, and
- responsive to the torque of the engine achieving the target value, command the engine to skip one or more fuel injector events of the engine during an inertia phase of the shift.
3 more elements
A vehicle comprising:
- an engine;
- a transmission coupled to the engine;
- an accelerator pedal;
- and
- a controller programmed to, during an upshift of the transmission, command the engine to skip one or more fuel injector events of the engine during an inertia phase of the upshift when the accelerator pedal is fully depressed, wherein the controller is further programmed to, during the shift, retard spark of the engine to reduce torque of the engine to a target value, and the skip is commanded after the torque of the engine achieves the target value.
2 more elements
A method of controlling a vehicle during an up shaft of a transmission, the method comprising:
- during an upshift of a transmission when the vehicle is in sport mode, selectively skipping one or more fuel injector events of the engine during an inertia phase of the upshift, wherein the number of skipped fuel injector events is based on accelerator pedal position.
