Abstract
An electronic shift system for a vehicle may include a card smart key including a permanent magnet, a base bracket formed with a guide slot for insertion and mounting of the smart key, the guide slot being configured to guide movement of the smart key mounted therein, and a Printed Circuit Board (PCB) fixedly disposed on the base bracket, the PCB configured to identify a mounting state of the smart key based on whether the permanent magnet approaches thereto when the smart key is inserted into the guide slot and to identify a shift stage based on variation in position of the permanent magnet when the smart key mounted in the guide slot is moved along the guide slot, so as to output a signal corresponding to the identified shift stage to a transmission control unit.
