Method and system for automatically controlling shift stage

A method for automatically controlling a shift stage, the method comprising:

• a shift stage check operation, by a shift stage sensing device, of detecting a position of the shift stage of a vehicle to check the shift stage;
• a driving and stopping sensing operation, by a driving and stopping sensing device, of detecting driving state information of the vehicle to determine whether the vehicle is in a driving or a stopping condition;
• a learning preparing operation, by a shift stage controlling device, of identifying whether the shift stage is shifted from a Drive stage (D stage) to an Neutral stage (N stage) when it is determined that the shift stage enters the stopping condition at the D stage by the shift stage check operation and the driving and stopping sensing operation;
• a learning operation, by the shift stage controlling device, of measuring a shifting time from when the shift stage enters the stopping condition at the D stage to when the shift stage is shifted to the N stage when it is identified that the shift stage is shifted from the D stage to the N stage in the learning preparing operation and storing the corresponding shifting time;
• and
• a learning execution operation, by the a shift stage controlling device, of automatically shifting the shift stage from the D stage to the N stage in the stored shifting time when the shift stage again enters the stopping condition at the D stage after the learning operation.
