The present invention provides an automatic parking assist system and an automatic parking assist method for a vehicle. According to the present invention, the automatic parking assist system for a vehicle comprises: a wheel speed sensor unit for sensing left and right wheel speed of a vehicle; a steering angle sensor unit for measuring a steering angle of the vehicle; and a control unit for calculating travel distances of the left and right wheels of the vehicle based on the sensed left and right wheel speeds and the measured steering angle, and cumulatively calculating an entry angle when the vehicle is parked based on the calculated travel distance. The present invention intends to minimize degradation of automatic parking control performance due to incorrect input of vehicle gear ratio in accordance with a state of a vehicle such as alignment of vehicle wheels.
