Temperature based clutch control

A vehicle includes a clutch to couple a motor and transmission, and a controller that, in response to a regenerative braking request and a temperature being within a first range, partially capacitizes the clutch for regenerative torque transfer therethrough with slip, and in response to another rege...

More Information
Summary:A vehicle includes a clutch to couple a motor and transmission, and a controller that, in response to a regenerative braking request and a temperature being within a first range, partially capacitizes the clutch for regenerative torque transfer therethrough with slip, and in response to another regenerative braking request and the temperature being within a second range less than the first, fully capacitizes the clutch prior to regenerative torque transfer therethough to preclude slip.
