Patent ID: 7749132

Claim:
A clutch engagement control apparatus for a hybrid vehicle, comprising: power sources; a clutch disposed between power sources and drive wheels and arranged to vary a transmission torque capacity; a clutch input speed sensing device to sense an actual clutch input speed of an input side of the clutch; a clutch output speed sensing device to sense an actual clutch output speed of an output side of the clutch; and a controller configured to: calculate a target vehicle driving torque in accordance with a driver's operation and a vehicle running condition; calculate a target clutch slip speed of the clutch in accordance with a vehicle running condition; calculate a target clutch input speed of the input side of the clutch and a target clutch output speed of the output side of the clutch in accordance with the target vehicle driving torque and the target clutch slip speed; calculate a target power source output torque of the power sources to reduce a clutch input speed deviation between the target clutch input speed and the actual clutch input speed; calculate a target clutch transmission torque capacity of the clutch to reduce a clutch output speed deviation between the target clutch output speed and the actual clutch output speed; control the power sources so as to control an actual power source output torque of the power sources toward the target power source output torque; and control the clutch so as to control an actual clutch transmission torque capacity of the clutch toward the target clutch transmission torque capacity.
