Abstract
Systems and methods for improving operation of a vehicle are presented. In one example, a controller notifies a human vehicle driver before electric power consumers that are electrically coupled to the vehicle are deactivated. The controller may notify the human driver in response to a state of charge of a vehicle battery.
Claims19
A method for operating an engine, comprising:
- via a controller, automatically stopping the engine;
- sending a notification to a human driver of a vehicle while the engine is automatically stopped that one or more electric power consumers coupled to the vehicle will be deactivated in a predetermined amount of time unless the human driver performs an engine reactivation procedure at the vehicle, where the human driver is not occupying the vehicle;
- and
- receiving notification via the controller from the human driver to deactivate the one or more electric power consumers to extend the predetermined amount of time.

A method for operating an engine, comprising:
- via a controller, automatically stopping the engine;
- sending a notification to a human driver of a vehicle while the engine is automatically stopped that one or more electric power consumers coupled to the vehicle and receiving electrical power from an electrical energy storage device will be deactivated in a predetermined amount of time unless the human driver performs an engine reactivation procedure at the vehicle, the human driver not occupying the vehicle;
- and
- evaluating an identity of the human driver occupying the vehicle after sending the notification.
1 more element
A vehicle system in a vehicle, comprising:
- an engine;
- one or more electrical energy consumers that are in selective electrical communication with an electric energy storage device;
- and
- an engine controller coupled to the engine, the engine controller including executable instructions stored in non-transitory memory to:
- automatically stop the engine via the controller;
- determine an electric energy device state of charge;
- and
- when a human driver is not occupying the vehicle, notify the human driver that the one or more electrical energy consumers will be deactivated when the human driver does not perform an engine starting procedure within a predetermined amount of time.
