A method of preventing an automatic transmission vehicle from rolling downward on a hill is provided. The method includes determining whether the vehicle travels normally or abnormally on the hill based on a gradient measured by a G sensor and a direction of a wheel measured by a wheel sensor. A controller is maintained in an off state when the vehicle travels normally based on driver intention. The method further includes determining whether to operate the controller by determining a difference in wheel speed between a front wheel and a rear wheel of the vehicle when the vehicle travels abnormally as the vehicle rolls downward.
