Method for efficiently managing ignition states for keyless ignition systems for vehicles with electronic shifter and electronic securement systems

1. A control system for a vehicle having an electronic shifter for a transmission, the control system comprising:

a poly-shifter, the poly-shifter configured to be moved between operating states including “Park” and “Non-Park” positions;

a radio frequency hub (RF Hub) that supports operational features of the vehicle;

a transmission control module (TCM) that determines a lock state of a parking pawl in the transmission and communicates the lock state to the RF Hub; and

a controller configured to:

determine whether a driver has exited the vehicle with the poly-shifter in a “Non-Park” position; and

power down the vehicle based on the lock state of the parking pawl being in a “Park” position and the determination that the driver has exited the vehicle with the poly-shifter in the “Non-Park” position.

2. The control system of claim 1 , wherein the controller is further configured to:

determine that the vehicle is in an engine auto-stop event and wherein the power down is further based on the vehicle in the engine auto-stop event.

3. The control system of claim 2 , wherein the controller is further configured to:

determine that the vehicle has not been keyed “OFF” and wherein the power down is further based on the vehicle not being keyed “OFF”.

4. The control system of claim 3 , wherein determining that the vehicle has not been keyed “OFF” comprises determining that an ignition status is “ON”.

5. The control system of claim 1 , wherein the “Non-Park” position comprises “Drive”.

6. The control system of claim 5 , wherein the controller determines that the driver has exited the vehicle based on a signal received by the controller indicative of at least one of a brake pedal being released, a vehicle door being opened or a seat belt removed.

7. The control system of claim 1 , wherein the controller is further configured to:

subsequent to power down, determine a driver has entered the vehicle; and

send a signal to a human machine interface (HMI) to communicate a message informing the driver that the poly-shifter was not properly returned to “Park”.

8. The control system of claim 1 , wherein the controller communicates a signal to change the lock state of the parking pawl to the “Park” position based on the driver exiting the vehicle with the poly-shifter in the “Non-Park” position.

9. The control system of claim 1 , wherein the “Non-Park” position comprises one of “Drive”, “Reverse” and “Neutral”.

10. The control system of claim 9 , wherein the controller is further configured to:

determine an ignition state to be in accessory (“ACC”) and wherein the controller communicates a signal to change the lock state of the parking pawl to the “Park” position based on the poly-shifter being in the “Non-Park” position and the ignition state being in the ACC state.

11. A method for powering off a vehicle having a poly-shifter, the poly-shifter configured to be moved between operating states including “Park” and “Non-Park” positions, the method comprising:

determining a lock state of a parking pawl in a transmission of the vehicle;

communicating the lock state to a radio frequency hub (RF Hub);

determining whether a driver has exited the vehicle with the poly-shifter in a “Non-Park” position; and

powering down the vehicle based on the lock state of the parking pawl being in a “Park” position and the driver exiting the vehicle with the poly-shifter in the “Non-Park” position.

12. The method of claim 11 , further comprising:

determining that the vehicle is in an engine auto-stop event and wherein the powering down is further based on the vehicle in the engine auto-stop event.

13. The method of claim 12 , further comprising:

determining that the vehicle has been keyed “OFF” and wherein the powering down is further based on the vehicle not being keyed “OFF”.

14. The method of claim 11 , further comprising:

determining that a driver has exited the vehicle based on at least one of a brake pedal being released, a vehicle door being opened or a seat belt being removed.

15. The method of claim 14 , further comprising:

subsequent to the powering down, determining whether a driver has entered the vehicle; and

communicating a signal to a human machine interface (HMI) indicative of a message informing the driver that the poly-shifter was not properly returned to “Park”.

16. The method of claim 11 , further comprising:

communicating a signal to change the lock state of the parking pawl to the “Park” position based on the determination that a driver has exited the vehicle with the poly-shifter in the “Non-Park” position.

17. The method of claim 11 , further comprising:

determining an ignition state to be in accessory (“ACC”); and

communicating a signal to change the lock state of the parking pawl to the “Park” position based on the poly-shifter being in the “Non-Park” position and the ignition being in the “ACC” state.

18. A method of powering off a vehicle having a poly-shifter, the poly-shifter configured to be moved between operating states including “Park” and “Non-Park” positions, the method comprising:

determining a lock state of a parking pawl in a transmission of the vehicle;

communicating the lock state to a radio frequency hub (RF Hub);

determining whether a driver has exited the vehicle with the poly-shifter in a “Park” position;

determining a circuit fault based on one of the poly-shifter and the lock state of the parking pawl; and

powering down the vehicle based on the lock state of the parking pawl being in a “Park” position and the driver exiting the vehicle with the poly-shifter in the “Park” position.

19. The method of claim 18 , further comprising:

subsequent to the powering down, determining whether a driver has entered the vehicle; and

communicating a signal to a human machine interface (HMI) indicative of a message informing the driver to service the transmission.
