Abstract:
The present invention relates to a gear shift control method and a gear shift control system of a hybrid vehicle capable of solving the dissatisfaction problem of a required torque during shift time reduction and gear shift by performing combined synchronization control of a target gear shift stage by using speed control of a driving motor during gear shift, and controlling pressure in order to obtain the required torque of a driver by a transmission clutch. For this, the gear shift control method of the hybrid vehicle using dynamic power of an engine and the driving motor may include the steps of: controlling the pressure of the transmission clutch for gear shift to the target gear shift stage; and controlling the speed of the driving motor in order for speeds of both stages of the transmission clutch to be synchronized.

PURPOSE: A starter motor control method for a hybrid vehicle, capable of minimizing the generation of vibration when starting an engine, is provided to minimize vibration delivered to a driving shaft and a car body and to improve the drivability of the vehicle by controlling the starting torque of a starter motor according to the traveling state of a vehicle after an engine starts. CONSTITUTION: A starter motor control method for a hybrid vehicle comprises the following steps: accelerating(S120) a stopped engine; determining(S120) whether the speed of the engine is faster than a preset value; injecting(S130) the fuel to the inside of the engine if the speed of the engine is faster than the preset value; deciding the torque of a starter motor according to the target speed of the engine; and controlling the speed of the engine according to the predetermined torque of the starter motor. [Reference numerals] (S110) Executing MG1 engine lift-up control; (S120) Engine speed > Preset value ?; (S130) Starting fuel injection to an engine; (S140) Executing MG1 starting speed follow-up control; (S150) Completing starting; (S160) Restricting the rising gradient of the engine speed for a predetermined time

PURPOSE: A shift control system and method are provided to prevent the reduction of speed of a second motor by applying torque to the second motor by using feed-forward control. CONSTITUTION: A first motor(MG1) controls engine cranking and engine speed. A second motor(MG2) directly transfers torque to the shaft of a vehicle. A first planetary gear set(20) interlinks an engine and the first motor. A second planet gear set(22) interlinks the engine and the second motor. A PI controller calculates torque corresponding to a target speed of the second motor while commanding the calculated torque to the second motor. An engine friction torque feed-forward unit inputs the torque corresponding to reaction force transferred to the second motor in the PI controller with a feed-forward term control method.
