Abstract: A system for parking control of a vehicle in which a transmission parking configuration is omitted is provided. The system includes a shift by wire device that requests a parking control of the vehicle when a parking stage is input by an operation of a driver. An electronic parking brake operates a brake installed on a drive wheel via a relay which is connected to be in a parking brake state when the electronic parking brake receives the parking control request from the shift by wire device. The shift by wire device switches the relay to directly operate the brake to be in the parking brake state when the shift by wire device receives a failure event, which indicates that a normal operation of the electronic parking brake is impossible, from the electronic parking brake.
