How to control the power-up 1 → 2 upshift in the back road

摘要

If the power-on 1 → 2 upshift shift occurs while driving on the back road by performing the release duty correction according to the driving road of the vehicle, if the vehicle is running on the back road in the above step to perform shift without running up shock, Calculating a torque converter slip amount (Sr) of the? As the torque converter slip amount Sr of the climbing road vehicle is calculated in the above step, the correction duty (DEL) is added to the first-speed release duty Drr according to the power-on 1 → 2 upshift shifting on the plain stored in the memory. It is composed of the steps of calculating and outputting 1 speed release duty (Drs) in the climbing road by preventing Dr. operation to prevent the occurrence of run-up during shifting, preventing shift shock, improving shifting feeling and improving riding comfort. There is.
