Method and control system for controlling an electronically controlled transmission in a vehicle propulsion system

1. A controller for an electronically controlled transmission in a vehicle propulsion system of a vehicle, the controller being programmed to:

disengage a clutch in the transmission to prevent a power flow through the transmission in response to an upshift paddle selector and a downshift paddle selector both being actuated together for a first predetermined time period; and

change a ratio of the transmission in response to an actuation of one of the upshift paddle selector and the downshift paddle selector while the clutch in the transmission is disengaged to prevent the power flow through the transmission.

2. The controller of claim 1 , wherein the controller is programmed to change the ratio of the transmission in further response to a deactuation of the one of the upshift paddle selector and the downshift paddle selector prior to the actuation of the one of the upshift paddle selector and the downshift paddle selector.

3. The controller of claim 1 , wherein the controller is programmed to change the ratio of the transmission in response to the actuation of the one of the upshift paddle selector and the downshift paddle selector for less than a second predetermined period of time.

4. The controller of claim 3 , wherein the second predetermined period of time is less than the first predetermined period of time.

5. The controller of claim 1 , wherein the controller is programmed to change the ratio of the transmission in response to a leading edge actuation of the one of the upshift paddle selector and the downshift paddle selector.

6. The controller of claim 1 , wherein the controller is further programmed to adjust an engine speed in response to the actuation of the one of the upshift paddle selector and the downshift paddle selector while the clutch in the transmission is disengaged to prevent the power flow through the transmission, wherein the controller is programmed to adjust the engine speed by being programmed to one of rev-match the engine speed to a transmission speed and momentarily blip the engine speed.

7. The controller of claim 1 , wherein the controller is further programmed to adjust an engine speed in response to both the upshift paddle selector and the downshift paddle selector being disengaged, wherein the controller is programmed to one of rev-match the engine speed to a transmission speed and momentarily blip the engine speed.

8. The controller of claim 1 , wherein the controller is further programmed to provide an audible feedback in response to the actuation of the one of the upshift paddle selector and the downshift paddle selector while the clutch in the transmission is disengaged to prevent the power flow through the transmission.

9. The controller of claim 8 , wherein the controller provides the audible feedback by being programmed to one of adjust an engine actuator, adjust a configuration of an exhaust system, and produce an audible sound through an audio system in the vehicle.

10. A method for controlling an electronically controlled transmission in a vehicle propulsion system of a vehicle, the method comprising:

disengaging a clutch in the transmission to prevent a power flow through the transmission in response to an upshift paddle selector and a downshift paddle selector both being actuated together for a first predetermined time period; and

changing a ratio of the transmission in response to an actuation of one of the upshift paddle selector and the downshift paddle selector while the clutch in the transmission is disengaged to prevent the power flow through the transmission.

11. The method of claim 10 , wherein the changing a ratio of the transmission is in further response to a deactuation of the one of the upshift paddle selector and the downshift paddle selector prior to the actuation of the one of the upshift paddle selector and the downshift paddle selector.

12. The method of claim 10 , wherein the changing of the ratio of the transmission is in response to the actuation of the one of the upshift paddle selector and the downshift paddle selector for less than a second predetermined period of time.

13. The method of claim 12 , wherein the second predetermined period of time is less than the first predetermined period of time.

14. The method of claim 10 , wherein the changing of the ratio of the transmission is in response to a leading edge actuation of the one of the upshift paddle selector and the downshift paddle selector.

15. The method of claim 10 , further comprising adjusting an engine speed in response to the actuation of the one of the upshift paddle selector and the downshift paddle selector while the clutch in the transmission is disengaged to prevent the power flow through the transmission, wherein the adjusting comprises one of rev-matching the engine speed to a transmission speed and momentarily blipping the engine speed.

16. The method of claim 10 , further comprising adjusting an engine speed in response to both the upshift paddle selector and the downshift paddle selector being disengaged, wherein the adjusting comprises one of rev-matching the engine speed to a transmission speed and momentarily blipping the engine speed.

17. The method of claim 10 , further comprising providing an audible feedback in response to the actuation of the one of the upshift paddle selector and the downshift paddle selector while the clutch in the transmission is disengaged to prevent the power flow through the transmission.

18. The method of claim 17 , wherein providing the audible feedback comprises one of adjusting an engine actuator, adjusting a configuration of an exhaust system, and producing an audible sound through an audio system in the vehicle.
