System and method of controlling shift for vehicle

A method of controlling shift for a vehicle, comprising:

• detecting data for a shift control;
• determining a short term driving tendency index based on the data;
• determining a long term driving tendency index of a driver based on the short term driving tendency index of the driver;
• determining a difference between the short term driving tendency index and the long term driving tendency index by subtracting the long term driving tendency index from the short term driving tendency index;
• determining whether the difference between the short term driving tendency index and the long term driving tendency index is greater than or equal to a reference index difference when the difference between the short term driving tendency index and the long term driving tendency index is greater than or equal to 0;
• determining whether the long term driving tendency index is smaller than a first predetermined long term driving tendency index when the difference between the short term driving tendency index and the long term driving tendency index is greater than or equal to the reference index difference;
• and
• controlling the shift according to a first corrected driving tendency index when the long term driving tendency index is smaller than the first predetermined long term driving tendency index.

• and
• controlling the shift according to a fourth corrected driving tendency index when the long term driving tendency index is smaller than the first predetermined long term driving tendency index.
