Abstract
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.
Claims15
A vehicle comprising:
- a clutch to couple a motor and transmission;
- and
- a controller programmed to, in response to a regenerative braking request and a temperature being within a first range, partially capacitize 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 capacitize the clutch prior to regenerative torque transfer therethough to preclude slip.
A vehicle comprising:
- a clutch configured to couple a motor and transmission;
- and
- a controller programmed to, in response to a temperature being within a first range, partially capacitize the clutch during propulsive torque transfer therethrough, and in response to another regenerative braking request and the temperature being within a second range less than the first, fully capacitize the clutch prior to regenerative torque transfer therethough.
A method comprising:
- by a controller,
- in response to a regenerative braking request and a temperature being within a first range, partially capacitizing a clutch, to couple a motor and transmission, during regenerative torque transfer therethrough;
- and
- in response to another regenerative braking request and the temperature being within a second range less than the first, fully capacitizing the clutch prior to regenerative torque transfer therethough.
