PARKING-SPACE-EXIT ASSIST SYSTEM

1 . A parking-space-exit assist system comprising:

a driver device owned by a driver; and

an assist device provided in a vehicle and configured to cause the vehicle to exit a parking space when it is determined that the driver device is within a prescribed distance from the vehicle or is expected to arrive at the vehicle within a prescribed amount of time.

2 . The parking-space-exit assist system of claim 1 , wherein the assist device comprises:

a first determiner configured to determine a distance between the driver device and the vehicle; and

a first controller configured to generate a control signal for causing the vehicle to exit the parking space when the distance between the driver device and the vehicle is within the prescribed distance.

3 . The parking-space-exit assist system of claim 2 , wherein:

the assist device further comprises a first generator configured to generate a parking-space-exit path of the vehicle; and

the first controller generates a control signal so that the vehicle exits the parking space according to the parking-space-exit path generated in the first generator.

4 . The parking-space-exit assist system of claim 3 , wherein the first generator generates the parking-space-exit path of the vehicle in consideration of a parking-space-exit direction selected by the driver and a parking-space-exit direction.

5 . The parking-space-exit assist system of claim 2 , wherein:

the assist device further comprises a second determiner configured to determine time taken for the driver device to reach the vehicle; and

the first controller generates a control signal for causing the vehicle to exit the parking space when the distance between the driver device and the vehicle is within the prescribed distance and/or when the time is a prescribed amount of time or less.

6 . The parking-space-exit assist system of claim 4 , wherein:

the assist device further includes a second generator configured to generate a parking-space-exit path of the vehicle; and

the first controller generates a control signal so that the vehicle exits the parking space according to the parking-space-exit path generated in the second generator.

7 . The parking-space-exit assist system of claim 6 , wherein the second generator generates the parking-space-exit path of the vehicle in consideration of a parking-space-exit direction selected by the driver and a parking-space-exit direction.

8 . The parking-space-exit assist system of claim 2 , wherein the driver device comprises:

a display unit;

a second controller configured to control a parking-space-exit application; and

a third controller configured to control operation of the driver device on the basis of a driver's selection received via the parking-space-exit application and information received from the assist device.

9 . The parking-space-exit assist system of claim 8 , wherein the second controller receives a selection on a parking-space-exit period of the vehicle and a selection on a parking-space-exit direction of the vehicle via the display unit and provides the selections to the third controller.

10 . The parking-space-exit assist system of claim 8 , wherein:

the driver device further includes a first module configured to receive position information of the driver device; and

the first determiner determines the distance between the driver device and the vehicle by using position information of the vehicle provided from a second module configured to receive the position information of the vehicle and by using the position information of the driver device.

11 . The parking-space-exit assist system of claim 2 , wherein the driver device comprises:

a button configured to receive a parking-space-exit assist selection from the driver;

an alarm unit configured to notify the driver of the fact that it is possible to cause the vehicle to exit the parking space; and

a fourth controller configured to transmit the driver's parking-space-exit selection information to the assist device when the driver provides a signal to the button.

12 . The parking-space-exit assist system of claim 11 , wherein:

the assist device further comprises a signal requester configured to generate a position request signal that requests for the position information of the driver device;

the driver device further comprises a signal generator configured to generate a position signal related to the position request signal; and

the first determiner determines the distance between the driver device and the vehicle by using speeds of the position request signal and the position signal and a time difference between time at which the position request signal is transmitted and time at which the position signal is received.
