<p><P>PROBLEM TO BE SOLVED: To provide a method for reducing a shock from speed transmission of an automatic transmission gear in which engine torque reduction (ETR) can be controlled even if any speed transmission occurs during speed transmission of an automatic transmission vehicle, and engine torques are changed during speed transmission. <P>SOLUTION: The method includes a step of detecting a power on up shift condition, a step for performing an engine torque reduction (ETR) control operation in response to engine torques detected at speed change beginning point (SB) or throttle valve opening (TH) during power on up shift transmission, a step for performing the engine torque reduction (ETR) control operation in response to engine torques after the transmission starting point (SB) too during the power on up shift transmission, and reduces a shock from speed transmission caused by change in power condition during transmission. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
