Disclosed is a method for controlling runup comprising the steps performing upshifting from a second speed to a third speed if throttle opening and vehicle speed are at predetermined levels; determining if runup occurring at the point where upshifting from the second speed to the third speed is performed, the determination of the occurrence of runup being performed based on turbine rpm, transmission output rpm and a second speed gear ratio; determining if a time rate of change in turbine rpm is less than 0 if runup is occurring; reducing a duty for a predetermined time period if the time rate of change in turbine rpm is greater than 0; and performing feedback control if the time rate of change in turbine rpm is less than 0. |
