Abstract:
A shift control method for selecting a target shift gear of a forward driving range when a shift lever changes from a reverse range to the forward driving range, comprising:detecting a shift lever position; detecting an engine revolution; detecting a throttle valve opening; detecting a vehicle speed; detecting a turbine shaft revolution speed of a torque converter; and selecting the target gear of the forward driving range based on at least one of the vehicle speed and the turbine shaft revolution speed, if the shift lever position is changed from the reverse range to the forward driving range, an engine revolution state is an idling state, and the detected throttle valve opening is not more than a first predetermined value, wherein a first gear is selected as the target gear if the vehicle speed is not more than a second predetermined value, and wherein the first gear is selected as the target gear if the vehicle speed is more than the second predetermined value and the turbine speed is not more than a third predetermined value.
