SELECTIVE POWERTRAIN HEATING SYSTEM

A vehicle includes a powertrain having an engine and at least one controller. The controller is programed to selectively heat at least one of a plurality of components of the powertrain with a given amount of waste heat based on an expected decrease in friction power associated with an expected incr...

More Information
Summary:A vehicle includes a powertrain having an engine and at least one controller. The controller is programed to selectively heat at least one of a plurality of components of the powertrain with a given amount of waste heat based on an expected decrease in friction power associated with an expected increase in temperature from the given amount of waste heat for each of the components.
