Smart parking assistant system and method of controlling parking alignment

1. A smart parking assistant system of a vehicle comprising:

a determination controller confirming a driver intention for performing an automatic parking alignment function that includes detecting left and right objects and automatically correcting a direction angle of the vehicle and distances between the vehicle and the left and right objects; and

a parking alignment controller performing the automatic parking alignment function when the driver intention is confirmed,

wherein the determination controller guides a second driver input for performing the automatic parking alignment function when a defined first driver input is generated, and confirms the driver intention when the second driver input is generated,

wherein the first driver input includes operations of preset times of a parking switch in a state that the vehicle is stopped, an ignition switch is turned-on and a gear stage is a neutral gear stage, and

wherein the second driver input includes an input of a defined first gear stage.

2. The smart parking assistant system of claim 1 , further comprising:

a perpendicular parking controller performing an automatic perpendicular parking function,

wherein the determination controller guides a driver input instructing the automatic parking alignment function when the automatic perpendicular parking function is completed, and confirms the driver intention when the driver input instructing the automatic parking alignment function is generated.

3. The smart parking assistant system of claim 2 , wherein the determination controller confirms presence of the driver intention when a reference distance and a reference direction angle are not satisfied during execution of the automatic perpendicular parking.

4. The smart parking assistant system of claim 2 , wherein the determination controller confirms that the driver intention is present when the defined first gear stage is input, and determines that the driver intention is absent when a defined second gear stage is input, and

wherein the perpendicular parking controller terminates the automatic perpendicular parking function after the automatic parking alignment function is completed when the driver intention is present, and terminates the automatic perpendicular parking function without performing the parking alignment function when the driver intention is absent.

5. A method of controlling parking alignment by a smart parking assistant system for a vehicle, the method comprising:

confirming, by the controller, a driver input for an automatic parking alignment function that includes detecting left and right objects and automatically correcting a direction angle of the vehicle and distances between the vehicle and the left and right objects in a manual parking mode; and

performing, by the controller, the automatic parking alignment function when the driver input is generated,

wherein the confirming the driver input includes:

confirming, by the controller, generation of a first driver input when operations of preset times of a parking switch in a state that the vehicle is stopped, an ignition switch is turned-on and a gear stage is a neutral gear stage;

outputting, by the controller, a sound announcement or a text announcement to guide input of a first gear stage when the first driver input is confirmed; and

confirming, by the controller, generation of a second driver input including when the first gear stage is input,

wherein the automatic parking alignment function is performed when the second driver input is generated.
