摘要: A transmission control system of an electric vehicle includes a motor configured to generate drive torque; a transmission configured to perform multi-stage shifting using a dog clutch in a restraint relationship with a one-way clutch configured to transmit forward power of the motor; a speed sensor configured to measure a rotation speed on an output side of the transmission; a motor control unit configured to control the drive torque from the motor according to a driver's accelerator position signal (APS) value; and a vehicle control unit configured to control the multi-stage shifting of the transmission according to a torque command based on the APS value, and to perform clutch alignment control by moving up a sleeve in a reverse direction to contact a hub through a reverse rotation operation of gear teeth by applying reverse rotation torque of predetermined drive force through the motor in a pre-engagement state of the dog clutch.

摘要: A system and method for electric oil pump control of hybrid electric vehicle are provided. The system includes a driving information detector that is configured to detect driving information according to driving of the hybrid vehicle and an operation type transmission of an electric oil pump (EOP) that receives and supplies transmission oil for operating a clutch. A controller analyzes the driving information, and detects an oil skew phenomenon and enters the EOP speed increasing mode when the hybrid vehicle stops by rapid braking, and increases the EOP speed to increase temporary oil absorption power during rapid starting in a predetermined reference period of time.
