<p>It is possible to reduce the torque drop caused by a transmission shock and a time lag in a hybrid system. When the transmission speed ratio is up-shifted in a hybrid system control method, a motor torque is instantaneously increased upon start of a half clutch control of a clutch and the motor torque is controlled to be zero or minus to compensate a vehicle drive torque increase by the engine rotation inertia during the half clutch control. When the clutch is completely connected, the motor torque is increased.After the increase of the torque, the motor torque is decreased with a predetermined time constant. When down-shift is performed, the motor torque is increased upon start of the half clutch control and the motor torque is decreased with a predetermined time constant from the increased torque so as to compensate the lowering of the vehicle drive torque by the engine rotation inertia, thereby smoothly making a connection to a torque-up amount upon a complete clutch connection.</p> |
