Abstract

Systems and methods for selectively activating operation of one or more vehicle powertrain elements are presented. In one example, a propulsion source of a vehicle is activated in response to a driver moving a shift lever from a first location to a second location. Further, activation of propulsion source may be made contingent on whether or not the vehicle is coupled to an electrical grid.

Claims

1. A method for enabling vehicle propulsion, comprising:

enabling propulsion of a vehicle after propulsion of the vehicle is deactivated in response to confirming presence of a driver via a remote device, confirming more than a threshold force is applied to a brake pedal, and shifting the vehicle from park or neutral into a forward or reverse propulsion mode, where the threshold force applied to the brake pedal is a force sufficient to stop vehicle motion.

2. The method of claim 1, where enabling propulsion of the vehicle includes starting an engine of the vehicle, and where propulsion of the vehicle is enabled in response to only confirmed presence of the driver, confirmed force applied to the brake pedal, and the vehicle being shifted from park or neutral into forward or reverse propulsion mode.

3. The method of claim 1, where enabling propulsion of the vehicle includes supplying current to a motor of the vehicle.

4. The method of claim 1, where the forward or reverse propulsion mode includes operating a transmission in a forward gear or a reverse gear.

5. The method of claim 1, further comprising enabling propulsion of the vehicle in response to confirmation of the driver gripping a steering wheel.

6. The method of claim 1, further comprising notifying the driver of one or more conditions for enabling propulsion of the vehicle are not met.

7. A method for enabling vehicle propulsion, comprising:

enabling propulsion of a vehicle after propulsion of the vehicle is deactivated in response to confirming presence of a driver via a polling device, confirming more than a threshold force is applied to a brake pedal, and confirming that the vehicle is not coupled to a power grid.

8. The method of claim 7, where confirmation that the vehicle is not coupled to a power grid is provided via an electrical connector pin sensor, and where propulsion of the vehicle is enabled in response to only confirmed presence of the driver, confirmed force applied to the brake pedal, confirming shifting the vehicle from park or neutral into a forward or reverse propulsion mode, and confirming that the vehicle is not coupled to the power grid.

9. The method of claim 7, where confirmation that the vehicle is not coupled to a power grid is provided via an electrical grid power sensor.

10. The method of claim 7, further comprising enabling propulsion of the vehicle responsive to shifting the vehicle from park or neutral into a forward or reverse propulsion mode.

11. The method of claim 7, where enabling propulsion of the vehicle includes starting an engine of the vehicle.

12. The method of claim 7, where enabling propulsion of the vehicle includes supplying current to a motor of the vehicle.

13. The method of claim 7, further comprising enabling propulsion of the vehicle in response to confirmation of the driver gripping a steering wheel.

14. A vehicle system, comprising:

a propulsion source; and

a controller including executable instructions stored in non-transitory memory to enable propulsion of a vehicle after propulsion of the vehicle is deactivated in response to confirming presence of a driver via a polling device, confirming more than a threshold force is applied to a brake pedal, and shifting a powertrain mode selector, where the powertrain mode selector is a forward or reverse selector.

15. The vehicle system of claim 14, where the powertrain mode selector is a manual gear shifter.

16. The vehicle system of claim 14, further comprising additional controller instructions to enable propulsion of the vehicle in response to confirmation of the driver gripping a steering wheel.

17. The vehicle system of claim 16, where enabling propulsion of the vehicle includes supplying current to a motor of the vehicle.

18. The vehicle system of claim 17, further comprising additional controller instructions to enable propulsion of the vehicle in response to confirmation of the driver gripping a shifter.
