Abstract: PURPOSE: A system and a method for controlling the shifting of an automatic transmission are provided to offer an improved shifting feeling by suppressing the generation of a shifting shock due to tip-up. CONSTITUTION: A control unit decides if a turbine torque is over a reference value when a 2-1 downshift request signal is outputted(S100,S110). If the turbine torque is over the reference value, a turbine change ratio is compared to a reference value(S120). If the turbine change ratio is smaller than the reference value, an output rpm is compared to a reference value(S130). If the output rpm is lower than the reference value, a duty control signal is outputted to a drive unit(S140). If the torque is less than the reference value or the same, the turbine change ratio is larger than the reference value or the same, or the output shaft rpm is over the reference value or the same, the turbine speed is controlled and the 2-1 downshift is inhibited(S200).

Abstract: PURPOSE: A system and a method for controlling the kick-down shift of an automatic transmission on a hill are provided to prevent the occurrence of a run-up shock by correcting a power on/off deciding condition depending on a power on/off deciding map. CONSTITUTION: A vehicle travel state sensing unit(10) senses the signals outputted from an atmospheric pressure sensor(11), a throttle valve opening degree sensor(120), a vehicle speed sensor(13), a speed range sensor(14), a turbine rpm sensor(15), an engine rpm sensor(16), and a kick-down switch(18) and outputs corresponding electrical signals. An engine control unit(20) decides the travel state on a hill and outputs a corresponding control signal. A transmission control unit(30) outputs a control signal by applying a target turbine change ratio map corrected depending on the reduced target turbine change ratio in kick-down shifting on the hill and outputs a transmission control signal corresponding to the kick-down shifting after reducing the turbine change ratio and correcting a power on/off deciding condition. A drive unit(40) performs kick-down shifting with response to the kick-down shifting control signal.
