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

A control apparatus of an automatic transmission includes an electric hydraulic pump including a motor and a pump, an actuator for engaging or releasing a friction element by controlling a hydraulic pressure discharged from the pump, and a transmission control unit (TCU) for correcting a control signal to control the actuator depending on a dynamic characteristic coefficient of the friction element and the actuator during shifting when outputting the control signal to the actuator.

Apparatus for controlling automatic transmission and method of controlling automatic transmission

An automatic transmission control apparatus includes an engine generating power by a combustion of fuel; an automatic transmission provided with a friction element including a clutch and a brake and changing the power generated in the engine into a torque required depending on a speed by an engagement and release of the friction element to be output; an accelerator pedal position sensor detecting a position signal of the accelerator pedal; and a controller determining whether a vehicle is in a rapid acceleration state from the position signal of the accelerator pedal detected from the accelerator pedal position sensor and correcting a control hydraulic pressure of the friction element if the vehicle is the rapid acceleration state. Since the friction element control hydraulic pressure is controlled depending on the operation speed of the accelerator pedal, the shift responsiveness may be improved.
