    Abstract: Methods and systems are provided for controlling operation of an engine of a vehicle to supply power to a power box that in turn supplies power to loads external to the vehicle. In one example, a method comprises, via a controller, detecting that the vehicle is in a condition of reduced air exchange, and in response to a request to operate the engine to supply power to the power box, alerting the vehicle operator of the condition and discontinuing engine operation if a response to the alert is not received within a threshold duration. In this way, engine control strategy may account for the condition of reduced air exchange when the vehicle operator has acknowledged that the engine is operating under such conditions.

    Abstract: A vehicle includes an engine, electrical loads, and at least one controller. While the engine is on, the controller calculates the change in current demand of the electrical loads expected from turning the engine off. The decision to command the engine off is then based on the expected change in current demand. Electrical loads that will change state from on to off when the engine is turned off will increase the expected change in current demand. Electrical loads that will change state from off to on when the engine is turned off will decrease the expected change in current demand. Operating conditions associated with the electrical loads, such as operating voltage, temperature, and speed, may affect the expected change in current demand.

    Abstract translation: 车辆包括发动机，电力负载和至少一个控制器。 当发动机打开时，控制器计算预期从关闭发动机的电力负载的当前需求的变化。 然后根据当前需求的预期变化来决定关闭发动机。 当发动机关闭时，将从开启状态变为关闭的电气负载将增加当前需求的预期变化。 当发动机关闭时，将从关闭状态改变为开状态的电气负载将减少当前需求的预期变化。 与电气负载（例如工作电压，温度和速度）相关的操作条件可能会影响当前需求的预期变化。
