In a method for controlling a clutch actuator for an automated manual transmission, when a driver's operation signal is input for operation of the clutch actuator, the hydraulic pressure of a hydraulic chamber of the clutch actuator forms pressure equilibrium with the atmospheric pressure through a pressure equilibrium control by standing by at a control-standby state before an actual stroke position of the clutch actuator enters a hydraulic pressure generation range from a hydraulic pressure release range. When the actual stroke position of the clutch actuator enters the hydraulic pressure generation range from the hydraulic pressure release range, the clutch actuator is moved to the predetermined stroke position by a predetermined operation speed, and then controlled to follow the driver's operation signal.

Method for controlling clutch actuator for automated manual transmission

A vehicle supercharging system may include: an engine; a transmission; a dual-turbine electric supercharger that compresses air and has a first turbine and a second turbine; an engine-side supercharging path part that branches out from an air supplying line configured to supply air to the engine, passes through the first turbine and then joins into the air supplying line; a transmission-side supercharging path part that sucks air separately from the engine-side air supplying line, passes through the second turbine, and then supplies compressed air to the transmission; and a controller that operates the dual-turbine electric supercharger according to a driving state of a vehicle and that individually controls valves provided in the engine-side supercharging path part and the transmission-side supercharging path part.

Vehicle supercharging system and control method thereof

A vehicle transmission system may include an engine outputting power from fuel combustion, a transmission coupled to the engine and including at least one clutch to control torque input from the engine, an supercharger compressing an intake air and supplying the compressed intake air to the engine, and a control unit, where, when a predetermined acceleration condition is satisfied, the control unit is configured to operate the supercharger and to control the transmission according to a transmission clutch stroke operation map corresponding to the operation of the electric supercharger, to vary an engagement speed of the clutch when the supercharger is operated.

Vehicle transmission system and a method thereof

An apparatus for moving a shift rail of a transmission may include a control shaft provided to be moved in a direction perpendicular to a plurality of shift rails by an actuator, a plurality of rollers protruding from one selected among a corresponding one of the shift rails and the control shaft, the rollers being formed on one of facing sides of the shift rail and the control shaft, and a cam protruding in an S-shaped form from a remaining one selected among the corresponding shift rail and the control shaft, on which no roller is formed, the cam being provided to selectively move the shift rails in an axial direction by moving while coming into contact at opposite sides thereof with the rollers depending on a distance by which the control shaft is moved.

Apparatus for moving shift rail of transmission

An automated manual transmission includes an input, an output disposed in parallel with the input, a common use planetary gear device disposed on the input or the output, a shift gear device in which a plurality of external gear mates having different shift ratios are disposed on the input and the output, and a friction member disposed to transmit the rotation power transmitted to the input at the time of the braking to the output through the external gear mates.
