1. An anti-jerk control method of an eco-friendly vehicle driving using a motor as a driving source, comprising:

  • calculating, by a controller, an actual speed of the motor;

    calculating, by the controller, a model speed of the motor;

    acquiring, by the controller, a gradient of a road, on which the vehicle is located, using a gradient detector;

    determining, by the controller, a speed offset value that corresponds to the acquired gradient;

    compensating, by the controller, the model speed by the speed offset value;

    calculating, by the controller, a motor vibration component using a difference between the compensated model speed and the actual speed of the motor;

    calculating, by the controller, anti-jerk compensation torque using the calculated motor vibration component;

    compensating, by the controller, a motor torque command using the calculated anti-jerk compensation torque; and

    adjusting, by the controller, driving of the motor based on the compensated motor torque command.
