Abstract
Methods and systems are provided for using a forced induction system of an engine on-board a vehicle as a source of compressed air to pressurize depressurized objects on-board and external to the vehicle. In one example, a method may include, in response to a pressure of the depressurized object being below a threshold pressure while the engine is off, fluidly coupling a discharge of a forced induction system to the depressurized object, wherein the engine includes the forced induction system, and pressurizing the depressurized object by supplying electrical power to the forced induction system.
Claims19
A method for pressurizing a depressurized object with an engine of a vehicle system, comprising:
- in response to a pressure of the depressurized object being below a threshold pressure while the engine is off and an anticipated power draw from a battery to pressurize the depressurized object being predicted to not discharge the battery below a threshold state of charge (SOC),
- fluidly coupling a discharge of a forced induction system of the engine to the depressurized object, and
- pressurizing the depressurized object by supplying electrical power to the forced induction system via the battery.
A method for a vehicle system including an engine and a forced induction system coupled to an intake passage of the engine, the method comprising:
- responsive to a first condition including an engine off state, a pressure of a depressurized object being below a threshold pressure while the engine is in the engine off state, and an anticipated power draw from a battery to pressurize the depressurized object being predicted to not discharge the battery below a threshold state of charge (SOC),
- fluidly coupling a discharge of the forced induction system to the depressurized object,
- inflating the depressurized object by supplying electrical power to the forced induction system, and
- displaying pressurization system data at a display interface, including a pressurization of the depressurized object as the depressurized object is being inflated, wherein the display interface is an interface screen of a mobile device.
A vehicle system, comprising:
- an engine;
- a forced induction system coupled to an intake air passage of the engine;
- puddle lights positioned at one or more side mirrors of the vehicle system;
- and
- a controller storing instructions in memory, executable to:
- responsive to a first condition including an engine off state a pressure of a depressurized object being below a threshold pressure while the engine is in the engine off state, and an anticipated power draw from a battery to pressurize the depressurized object being predicted to not discharge the battery below a threshold state of charge (SOC),
- fluidly coupling a discharge of the forced induction system to the depressurized object, where the depressurized object is external to the engine,
- pressurizing the depressurized object by supplying electrical power to the forced induction system, and
- displaying pressurization system data via the puddle lights.
