In addition, according to the present disclosure, it is possible to detect the position of an occupant, the number of the occupant, and the classification of the occupant (an adult, a kid, or an object) on the vehicle through an ROA-based internal vehicle sensor.

Therefore, according to the present disclosure, the position of each seat may be exactly adjusted using the number of digital keys, the exact positions of the digital keys, the positions of the occupants in the vehicle, the number of the occupants, and the classification of the occupants, thereby increasing the convenience of the occupant.

Therefore, according to the present disclosure, when a digital key user, who has used the vehicle, gets on a vehicle with a smartphone, and starts the vehicle, the digital key user may obtain a previous seat position without personally moving the seat regardless of seating positions.

FIG. 4 is a schematic view illustrating the procedure of controlling a vehicle seat, according to an embodiment of the present disclosure.

Referring to FIG. 4, the vehicle 10 performs UWB communication with the digital key 300, and receives the sensing result of the interior of the vehicle and the determination result of the fastening state of a seat belt, from the ROA.

The vehicle 10 may control a vehicle seat for each occupant based on the number and the position of the digital key 300, the number of an occupant, the type of the occupant, and the position of the occupant. The vehicle 10 may control the vehicle seat for each occupant using vehicle seat information included in user information received from the server 400 (cloud server) through the digital key 300.

Hereinafter, a method for controlling a vehicle seat according to an embodiment of the present disclosure will be described in detail with reference to FIG. 5. FIG. 5 is a flowchart illustrating the method of controlling a vehicle seat, according to an embodiment of the present disclosure.

Hereinafter, it is assumed that the vehicle seat controlling apparatus 100 of FIG. 1 performs a processor of FIG. 5. In addition, in the following description made with reference to FIG. 5, it may be understood that the operation described as being performed by the vehicle seat controlling apparatus 100 is controlled by the controller 130 of the vehicle seat controlling apparatus 100.

Referring to FIG. 5, the vehicle seat controlling apparatus 100 authenticates a digital key user when the digital key 300 approaches the vehicle (S101).

When the digital key user is successfully authenticated, the vehicle seat controlling apparatus 100 identifies the position and the number of a digital key inside the vehicle (S102). The vehicle seat controlling apparatus 100 may identify the positions and the number of the digital key inside the vehicle by making the UBW communication with the digital key after the user gets on the vehicle.

Accordingly, the vehicle seat controlling apparatus 100 determines whether the number of the digital key 300 is 1 (S103) and the number of an occupant inside the vehicle is equal to the number of a digital key 300 (S104).

The vehicle seat controlling apparatus 100 determines whether an occupant fastens a seat belt after the vehicle is started, when the number of an occupant inside the vehicle is equal to the number of the digital keys 300 (S105). In this case, the vehicle seat controlling apparatus 100 may determine whether the occupant fastens the seat belt, based on the ROA.

Thereafter, the vehicle seat controlling apparatus 100 controls the seat position based on the seat position information, which is previously stored, of the digital key received from the digital key (S106). In this case, the digital key receives the seat position information from the server 400 and transmits the seat position information to the vehicle seat controlling apparatus 100.

Meanwhile, when at least two digital keys are provided in operation S103, the vehicle seat controlling apparatus 100 determines an occupant condition (S107). The occupant condition may include the position of an occupant, the number of the occupant, and the classification of the occupant (an object, an adult, or a kid).

Accordingly, the vehicle seat controlling apparatus 100 determines a target for seat-controlling based on the number of the digital key, the position of the digital key, and the occupant condition (S108), and controls the seat based on seat position information, which is previously stored, of each digital key (S106).

FIGS. 6A and 6B are views illustrating that one occupant is present inside a vehicle and one digital key is present inside the vehicle, according to an embodiment of the present disclosure.

Referring to reference numeral FIG. 6A, when one occupant is present inside the vehicle, and one digital key is provided inside the vehicle, when the position of the digital key inside the vehicle is matched to a seating position of the occupant who has registered the digital key, the vehicle seat controlling apparatus 100 determines that the occupant, who has registered the digital key, is a driver, determines whether the occupant fastens the seat belt after starting the vehicle, and controls the position of the relevant seat based on the previously-stored seat control information when the occupant fastens the seat belt.

Referring to reference numeral FIG. 6B, when one occupant is present inside the vehicle and one digital key is provided in the vehicle, and when the position of the digital key inside the vehicle is different from the seating position of the occupant who has registered the relevant digital key, the vehicle seat controlling apparatus 100 may sense the occupant condition, determine the target for seat-controlling, and control the seat after the occupant is determined as fastening the seat belt.

The detailed procedure of determining the target for seat-controlling based on the occupant condition, the number of digital key, and the position of the digital key will be described with reference to FIGS. 7 to 11.

FIGS. 7A-7E are views illustrating the procedure of controlling a vehicle seat when one digital key is provided, according to an embodiment of the present disclosure.

Referring to FIG. 7A, when one digital key 300 is provided inside the vehicle, and one occupant is seated on a driver seat, and when the position of the digital key is matched to the position of the occupant, the vehicle seat controlling apparatus 100 determines that the occupant is determined as a driver who has registered the digital key.

In addition, when one digital key 300 is provided inside the vehicle and two occupants are sensed, and when one of the two occupants is an adult and a remaining one of the two occupants is a kid, the vehicle is started on regardless of the position of the adult of the occupants, it is determined that the seat belts are fastened, and the driver seat is automatically moved and adjusted based on the seat control information which is previously stored. In this case, the digital key positioned in the driver seat is involved in starting the vehicle.

In other words, as in FIG. 7B, when a user having the digital key approaches the vehicle, an access authentication and a user authentication are performed. The authentications are successful, so a vehicle door is open, and the user gets on the vehicle as in FIG. 7C. In this case, it may be recognized that the position of the digital key is matched to the position of the occupant. When the seat belt of the driver seat is fastened as in FIG. 7D, the driver seat is controlled based on the seat control information, which is previously stored, as in FIG. 7E.

FIGS. 8A-8C are views illustrating the procedure of controlling a vehicle seat when two digital keys are provided and two occupants are present in addition to a driver, according to an embodiment of the present disclosure.

Hereinafter, seat controlling will be described with reference to FIG. 8A, when two digital keys are sensed inside the vehicle and two adults are sensed as occupants in addition to one driver.

As shown in FIG. 8B, when three occupants on a driver seat, a passenger seat, and a right seat in a rear row are sensed, and when digital keys are present only in the driver seat and the passenger seat, the vehicle seat controlling apparatus 100 senses whether three occupants are adults, kids, or objects. Then, when three occupants are all adults, the vehicle is started on based on the digital key positioned in the driver seat and it is determined whether the seat belt of each seat is fastened. When the seat belts are determined as being fastened as FIG. 8C, the vehicle seat controlling apparatus 100 controls the driver seat and the passenger seat having digital keys 311 and 312. In other words, the vehicle seat controlling apparatus 100 may control the driver seat based on the seat control information received from the digital key of the driver, and may control the passenger seat based on the seat control information received from the digital key of the passenger. In this time, the seat in the rear row, at which the occupant is seated, may not be controlled because a digital key is absent in the seat.

FIGS. 9A-9E are view illustrating the procedure of controlling a vehicle seat when two digital keys are provided and three occupants are present, according to an embodiment of the present disclosure.

Referring to FIG. 9A, when two digital keys are present in the vehicle and when occupants are seated on the driver seat, the passenger seat, and the seat in the rear row, the vehicle seat controlling apparatus 100 measures the position of each digital key, and senses whether the occupants are adults, kids, or objects.

As in FIG. 9B, when the digital keys are present in the driver seat and the passenger seat, and when an occupant seated on the seat in the rear row is a kid, the vehicle seat controlling apparatus 100 determines whether the seat belts of the driver seat and the passenger seat are fastened.

As in FIG. 9C, when the digital keys 311 and 312 are positioned in the driver seat and the passenger seat, respectively, the vehicle seat controlling apparatus 100 may control the position of the driver seat based on the seat control information received from the digital key of the driver seat and may control the position of the passenger seat based on the seat control information received from the digital key of the passenger seat.

When an image is shown to the kid through a smartphone serving as the digital key 313, the vehicle seat controlling operation is performed as in FIG. 9D or 9E.

In FIG. 9D, when digital keys are provided in the driver seat and the seat in the rear row, and a digital key is absent in the passenger seat, the vehicle seat controlling apparatus 100 determines the user of a digital key, through which the kid seated on the seat in the rear row views an image, as an occupant seated on the passenger seat. Accordingly, the vehicle seat controlling apparatus 100 controls the position of the driver seat based on the seat control information received from the digital key of the driver seat and may control the seat of the passenger seat based on the seat control information received from the digital key positioned at the seat in the rear seat.

FIG. 9E illustrates the case that four occupants including a kid are present in total. In this case, digital keys are positioned in the driver seat and the right seat in the rear row, at which occupants are seated, and digital keys are absent in the passenger seat and the left seat in the rear row. In this case, it may not be determined whether the user of the digital key positioned in the right seat in the rear row is the occupant at the passenger seat or at the left set in the rear row. Accordingly, the vehicle seat controlling apparatus 100 may control only the position of the driver seat based on the seat control information received from the digital key at the driver seat and may not control the positions of the passenger seat and the left seat in the rear row.

FIGS. 10A-10C are views illustrating the procedure of controlling a vehicle seat when three digital keys are provided and four occupants are present, according to an embodiment of the present disclosure.
