Shared clutch control for manual transmission with a hybrid drive

A vehicle comprising:

• a manual transmission;
• an internal combustion engine, selectively coupled to the manual transmission through a clutch;
• the clutch, configured to decouple the internal combustion engine from the manual transmission when disengaged;
• an ECU;
• a shuttle valve, the shuttle valve comprising a first inlet, a second inlet, and an outlet, wherein the shuttle valve operates to:
• in response to receiving first fluid at the first inlet and second fluid at the second inlet, route the greater pressure fluid among the first fluid and the second fluid out the outlet to a hydraulic-mechanical linkage, wherein clutch-related inputs from a driver of the vehicle send the first fluid to the first inlet and clutch-related inputs from the ECU send the second fluid to the second inlet, and wherein the clutch-related input signals from the ECU are generated by the ECU autonomously or semi-autonomously;
• and
• the hydraulic-mechanical linkage, configured to adjust engagement of the clutch based on fluid pressure.

A vehicle comprising:

• a clutch, configured to decouple an internal combustion engine of the vehicle from a manual transmission of the vehicle when the clutch is disengaged;
• and
• a hydraulic-mechanical linkage, configured to:
• receive at least one of a first fluid compressed by clutch-related input signals from a driver of the vehicle and a second fluid compressed by clutch-related input signals from an ECU;
• and
• adjust engagement of the clutch in accordance with the greater pressure fluid among the first fluid and the second fluid;
• wherein the hydraulic-mechanical linkage comprises:
• a first concentric circle configured to push on a diaphragm spring of the clutch based on a pressure of the first fluid, and
• a second concentric circle, having a different diameter than the first concentric circle, configured to push on the diaphragm spring of the clutch based on a pressure of the second fluid.
