Abstract
Systems and methods for improving shifting of a transmission are described. The systems and methods may be applied to automatic or manual transmissions, but the systems and methods may be particularly suited for automatic transmissions. In one example, electrical input to an alternator and electrical output from the alternator is adjusted in response to a request to upshift a transmission.
Claims20
A method for improving transmission shifting, comprising:
- increasing a field current of an alternator and reducing electrical output of the alternator to electrical loads applied to the alternator to maintain or reduce a load the alternator applies to an engine via a controller in response to a request to upshift a transmission.
A method for improving transmission shifting, comprising:
- increasing a field current of an alternator and shorting three coils of the alternator together via closing three transistors via a controller while upshifting a transmission.
A system for shifting a transmission, comprising:
- an engine;
- an alternator coupled to the engine;
- a transmission coupled to the engine;
- and
- a controller including executable instructions stored in non-transitory memory to increase a field current of the alternator and reduce electrical output of the alternator to electrical loads applied to the alternator to maintain or reduce a load the alternator applies to the engine in response to a request to upshift a transmission.
