Shock prevention device in case of 3rd speed to 1st speed kick down and its prevention method

摘要

The present invention relates to a shock prevention device and a method for preventing the shock during the 3rd speed → 1st speed kick down, and a shift detection unit (11) for detecting the shift of the transmission; A shift controller 12 which receives the output of the shift detector 11 and outputs a pressure control duty signal by performing feedback control to reduce shift shock when a jump shift occurs; It includes the pressure control unit 13 for receiving the output of the shift control unit 12, the hydraulic pressure during the shift, by reducing the shift shock through the feedback control, the shift quality (S / Q; Shift Quality) The present invention relates to a shock prevention device and a method of preventing the shock at the 3rd speed to the 1st speed kick down, which have an effect of improving the ride quality.
