发明名称 METHOD FOR IMPROVING SHIFT FEELING IN POWER-OFF UPSHIFTING AFTER CREEP
摘要 PURPOSE: A method for improving the shift feeling in power-off upshifting after creep is provided to improve the shift feeling and the durability of a clutch by reducing the shock due to sudden engagement of a brake and temporary connection of a front clutch. CONSTITUTION: A method for improving the shift feeling in power-off upshifting after creep comprises the steps of deciding if an accelerator switch is turned on in the upshifting state from a first speed to a second speed(S2), deciding if a prior shift stage is the creep stage in the accelerator switch-on state(S3), deciding the completion of speed change if the prior shift stage is the creep stage(S4), reducing a duty in a specific slope if a specific section(b) is not passed and a completion flag is not 1(S11), deciding if a kickdown servo switch is in the off state(S8), setting up a completion flag as 1 if the kickdown servo switch is in the off state(S9), reducing a duty if a start flag is 1(S12), checking motion for a specific time(S13), and setting up a duty as zero if a specific time is elapsed(S15).
