    • A shift control method for an automatic transmission includes the steps of outputting a predetermined shift control signal while driving in a second speed for controlling shifting into a third speed if signals indicating that shifting from the second speed into the third speed are applied; determining if third speed synchronization is completed; or determining if a tip-in signal has been applied if third speed synchronization is not completed; outputting a throttle compensation duty and determining if signals corresponding to 3-2 kickdown shifting are received if a tip-in signal is applied during third speed synchronization; comparing an oil temperature with a first predetermined value if signals corresponding to 3-2 kickdown shifting are received; comparing a vehicle speed with a second predetermined value if the oil temperature is greater than or equal to the first predetermined value; detecting an On/Off state of a kickdown switch if the vehicle speed is greater than or equal to the second predetermined value; performing 3-2 kickdown shift control during shifting from the second speed to the third speed if the difference of turbine rpm and engine rpm is greater than or equal to the third predetermined value.
    • 用于自动变速器的变速控制方法包括以下步骤:如果指示从第二速度转换到第三速度的信号被施加,则以用于控制换档成三速的第二速度的驱动而输出预定的换档控制信号; 确定第三速度同步是否完成; 或者如果没有完成第三速度同步,则确定是否应用了提示信号; 输出节气门补偿占空比,并且如果在第三速度同步期间施加了尖入信号,则确定是否接收到对应于3-2降档换档的信号; 如果接收到对应于3-2下降移位的信号,则将油温与第一预定值进行比较; 如果油温度大于或等于第一预定值,则将车速与第二预定值进行比较; 如果车速大于或等于第二预定值,则检测降档开关的开/关状态; 如果涡轮转速和发动机转速的差异大于或等于第三预定值,则从第二速度转换到第三速度时执行3-2降档变速控制。
