发明名称 Method for controlling shift during shift of automatic transmission
摘要 A method for controlling a shift during a shift of an automatic transmission controls to complete an N to N-2 shift and an N-2 to N-3 shift simultaneously such that the shift during a shift is smoothly performed when the N-2 to N-3 shift where one frictional element is released is required to be performed during the N to N-2 shift where another frictional element is released and the other frictional element is engaged. A method for controlling a shift during a shift of an automatic transmission may overlap an N to N-2 shift where a first frictional element is engaged and a second frictional element is released with an N-2 to N-3 shift where a third frictional element is released, wherein a release of the second frictional element begins after an engagement of the first frictional element begins, and a release of the third frictional element begins after an N-2 to N-3 shift signal is detected, wherein the engagement of the first frictional element and the release of the second and third frictional elements are simultaneously completed
