Abstract
A method for operating a hybrid vehicle that includes a high voltage and a low voltage bus is described. In one example, the method includes lowering a high voltage power consumption threshold so that high voltage bus power consumers may be identified as power consumers that may be deactivated as part of a load shedding operation. The high voltage power consumption threshold may be based on an amount of electric power that may be provided via an internal combustion engine and an electric machine.
Claims20
A method for operating a vehicle, comprising:
- shedding high voltage bus electric loads in response to high voltage bus electric loads being in excess of engine and electric machine electric power generation capacity for engine speeds less than a threshold speed.
A vehicle system, comprising:
- an internal combustion engine;
- an electric machine;
- a traction battery;
- a high voltage bus electrically coupling the electric machine and the traction battery;
- a controller including executable instructions stored in non-transitory memory that cause the controller to lower a high voltage load threshold in response to a state of charge (SOC) of the traction battery depleting over a plurality of time intervals.
A method for operating a vehicle, comprising:
- in response to a high voltage battery state of charge (SOC) being less than a target minimum high voltage battery SOC, lowering a high voltage power consumption threshold.
