Abstract
Systems and methods for operating a vehicle driveline that includes an engine and an electric machine are described. In one example, an amount of electrical power that is available to electrical consumers that are electrically coupled to a high voltage bus is adjusted responsive to a temperature of a catalyst for the purpose of reducing engine emissions.
Claims20
A vehicle driveline operating method, comprising:
- via a controller, decreasing an amount of power supplied to high voltage accessories coupled to a high voltage bus responsive to a desired engine power amount plus an electric energy storage device discharge power upper threshold amount minus an amount of power supplied to the high voltage accessories coupled to high voltage bus being greater than a driver demand power.
An engine operating method, comprising:
- via a controller, decreasing an amount of power supplied to an electric machine that provides propulsive torque to a vehicle driveline and increasing an amount of power supplied to high voltage accessories coupled to a high voltage bus responsive to efficiency of a catalyst in an engine exhaust system increasing.
A system, comprising:
- vehicle driveline including an engine and an electric machine that provide propulsive force to vehicle wheels;
- a high voltage bus coupled to a plurality of electrical power consumers;
- and
- a controller including executable instructions stored in non-transitory memory to decrease an amount of power supplied to at least one of the plurality of electrical power consumers responsive to a driver demand power being greater than an electric energy storage device discharge power upper threshold amount minus an amount of power supplied to the plurality of high voltage accessories.
