Shift control method when shift occurs during shift of automatic transmission

摘要

The present invention relates to a shift control method when a shift occurs during shifting of an automatic transmission, the method comprising: determining whether a traveling vehicle is shifting; Determining whether the shift of the shift stage while driving is in a power-off up shift state; Determining whether the target shift stage is greater than or equal to the set shift stage; Setting a holding time so that a shift does not occur even when the accelerator pedal is operated for a predetermined time; Determining whether the opening amount of the throttle valve is 50% or more; Determining whether the shift state of the shift stage is an upshift shift state; Selecting the target gear stage and returning to the initial stage can prevent frequent shifts caused by the frequent operation of the accelerator pedal, which can prevent shift shock and improve the sense of shift, and improve the durability of the automatic transmission. It works.
