The present invention discloses an apparatus and a method for controlling transmission of a hybrid vehicle. According to the present invention, an input side torque of a transmission is estimated as a predetermined value in a case where a transmission request signal is a transmission request from a neutral gear to a drive gear or a reverse gear, and then slip control is performed on an under-driver brake friction element of a gear box in a case where the transmission request signal is the transmission request from the neutral gear to the drive gear, and slip control is performed on a 35 R clutch of the gear box in a case where the transmission request signal is the transmission request from the neutral gear to the reverse gear. Since the input side torque is estimated as the predetermined value, an input side rotational speed increases, an impulse of the transmission that is generated by the increased input side rotational speed is removed, and a noise and a transmission shock that are generated by the increase in the input side torque of the transmission through motor torque control after the completion of the transmission can be fundamentally removed. [Reference numerals] (101) Receive a request signal of transmission from a current neutral (N) gear to a drive (D) gear or an R gear; (103) Maintain an input side torque of a transmission at a predetermined value (0 Nm); (105) Is a request for transmission from the neutral (N) gear to the drive (D) gear present?; (107) Slip control on an under-driver brake friction element and engagement of the gear; (109) Is the transmission completed?; (111) Increase the input side torque through engine torque control; (113) Slip control on a 35 R clutch and engagement of the gear; (AA) Start; (BB) End |
