1. An anti-pinch control system comprising:
a motor configured to generate driving force for moving a seat of a vehicle;
a current measurement sensor configured to measure a value of the current generated by the motor;
a database unit configured to store the values of current measured by the current measurement sensor; and
a controller configured to vary an anti-pinch value of the seat based on an average of a plurality of values of current measured every preset measurement period for a predetermined time, stored in the database unit,
wherein the plurality of values of current is values of current measured before the predetermined time based on a current time,
wherein the controller comprises:
a first calculator configured to derive averages of each of sets of values of current measured using each of the plurality of preset measurement periods; and
a second calculator configured to derive a minimum value of values obtained by adding a preset value of current for recognizing pinch to the average, as the anti-pinch value.
