摘要： A vehicle supercharging system and a control method thereof are disclosed. The vehicle supercharging system includes: an engine generating power according to combustion of a fuel; a transmission including at least one friction clutch; an electric supercharger that compresses air by rotational force of a motor; an engine-side supercharging path part branching from an air supplying line that supplies air to the engine, passing through the electric supercharger, and joining the air supplying line; a transmission-side supercharging path part that sucks air separately from the engine-side air supplying line, passes through the electric supercharger, and supplies compressed air to the transmission; and a controller that operates the electric supercharger according to a driving state of a vehicle and that controls the engine-side supercharging path part for boosting the engine and the transmission-side supercharging path part for cooling or warming the transmission through control of valves.

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.
