Patent ID: 8116957

Claim:
A system for controlling clutch engagement in a hybrid vehicle including a clutch disposed between an engine and a motor, the system comprising: a determination unit for selecting an engagement mode from a plurality of clutch engagement modes based on a vehicle state, a clutch engagement interrupt request, and a clutch slip request: a first control unit for calculating an engine torque command and a VFS current command for adjusting a speed difference between both sections of the clutch; and a second control unit for calculating a motor torque command for adjusting a torque transmitted to the vehicle during clutch engagement, wherein the second control unit comprises: a clutch model unit for calculating a current-time clutch transmission torque by receiving a slip amount, a clutch design specification, a current-time clutch pressure, and a clutch friction coefficient according to an oil temperature; and a motor torque command calculation unit for calculating a motor torque command by a difference obtained by comparing the current-time clutch transmission torque calculated by the clutch model unit and a driver demand torque.
