Abstract

A number of variations may include a clutch system having a clutch; a first cylinder operatively connected to the clutch; a passive valve operatively connected to the first cylinder; a hydraulic power pack actuator and a second cylinder operatively connected to the passive valve; an electronic control unit operatively connected to the hydraulic power pack actuator; and a clutch pedal operatively connected to the second cylinder.

First claim

What is claimed is:

1. A method comprising:
automatically controlling a manual clutch comprising:
operatively connecting a hydraulic power pack actuator to a passive valve which is operatively connected to a clutch, wherein the hydraulic power pack actuator is a centrifugal electro-hydraulic actuator;
operatively connecting an electronic control unit to the hydraulic power pack actuator; and
controlling the hydraulic power pack actuator with the electronic control unit to automatically modulate a pressure to the passive valve to cause the clutch to go into at least one of an ON, OFF, or slipping mode based on at least one vehicle condition.

2. The method of claim 1 further comprising:
manually controlling the manual clutch comprising:
operatively connecting a clutch pedal to the passive valve and manually engaging or disengaging the clutch pedal to increase or decrease pressure to the passive valve to cause the clutch to go into at least one of the ON, OFF, or slipping mode.

3. The method of claim 2 wherein the hydraulic power pack actuator causes the clutch to go into the OFF mode if a first pressure from the hydraulic power pack actuator is greater than a second pressure from the clutch pedal and wherein the clutch pedal causes the clutch to go into the OFF mode if the second pressure from the clutch pedal is greater than the first pressure from the hydraulic power pack actuator.

4. The method of claim 1 wherein the at least one vehicle condition includes at least one of a creep, a launch, an anti-stall, or a semi-autonomous driving condition.

5. The method of claim 1 wherein the electronic control unit comprises at least one software algorithm which is configured to automatically modulate the pressure to the passive valve to cause the clutch to go into at least one of the ON, OFF, or slipping mode.

6. The method of claim 5 wherein the at least one software algorithm is configured to enhance at least one of a stop-start or stop-start coasting condition.

7. The method of claim 5 wherein the at least one software algorithm is configured to enable a sailing condition.

8. The method of claim 1 wherein the clutch is a dry clutch.

9. The method of claim 1 wherein the clutch is a wet clutch.

10. A product comprising:
a clutch system comprising:
a clutch;
a first cylinder operatively connected to the clutch;
a passive valve operatively connected to the first cylinder;
a hydraulic power pack actuator and a second cylinder operatively connected to the passive valve, wherein the hydraulic power pack actuator is a centrifugal electro-hydraulic actuator;
an electronic control unit operatively connected to the hydraulic power pack actuator; and
a clutch pedal operatively connected to the second cylinder.

11. The product as set forth in claim 10 further comprising a reservoir operatively connected to the second cylinder and the hydraulic power pack actuator.

12. The product of claim 10 wherein the electronic control unit includes at least one software algorithm which controls the hydraulic power pack actuator to modulate the pressure to the passive valve to cause the clutch to go into at least one of the ON, OFF, or slipping mode based on at least one vehicle condition.

13. The product of claim 12 wherein the at least one vehicle condition includes at least one of a creep, a launch, an anti-stall, or a semi-autonomous driving condition.

14. The product of claim 12 wherein the at least one software algorithm is configured to enhance at least one of a stop-start or a stop-start coasting condition.

15. The product of claim 12 wherein the at least one software algorithm is configured to enable a sailing condition.

16. The product of claim 10 wherein the clutch is set to the OFF mode by the hydraulic power pack actuator if a first pressure from the hydraulic power pack actuator is greater than a second pressure from the clutch pedal and wherein the clutch is set to the OFF mode by the clutch pedal if the second pressure from the clutch pedal is greater than the first pressure from the hydraulic power pack.

17. The product of claim 10 wherein the clutch is a dry clutch.

18. The product of claim 10 wherein the clutch is a wet clutch.
