Patent Application
20230080898
This application is based on and claims under 35 U.S.C. § 119 the benefit of Korean Patent Application No. 10-2021-0122322, filed on Sep. 14, 2021, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety.
The disclosure relates to a vehicle and a control method, and more particularly, to a vehicle capable of providing a seat memory system and a control method thereof.
In general, a vehicle is provided with a seat for comfort of a driver.
In addition, various electronic control systems are applied to a vehicle. Due to this, various devices and systems in a vehicle that were previously manually controlled are also being controlled electronically.
As an example, a seat position of a vehicle may also be controlled. While previously, a method of controlling the seat position by rotating or pulling a lever was used, recently, a method of electronically controlling the seat position has been used.
For example, when a vehicle is started, depending on conditions in getting on and off the vehicle, the seat position of the vehicle set by the driver may be automatically controlled.
A motor is required to electronically control the seat position of a vehicle. In addition, various sensors and control modules for controlling the motor may be required.
However, a conventional electronic control method of controlling the seat position may not distinguish between an intentional adjustment of the seat position of the driver and an unintentional adjustment of the seat position of the driver, and even in a situation in which the driver is changed, seat automatic control may be performed based on a final seat position, which causes inconvenience in that the driver has to separately perform a position manipulation again.
It is an aspect of the disclosure to provide a vehicle and a control method thereof capable of adjusting a seat position in consideration of the body type of a driver, and identifying seat positions in getting on and off by determining whether the adjustment of seat position matches an intention of the driver.
Additional aspects of the disclosure will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the disclosure.
In accordance with an aspect of the disclosure, a vehicle includes a vehicle seat, a sensing device including a camera provided to obtain image data toward an outer lateral direction of a driver seat of the vehicle, a seat motor provided to implement a movement including at least one of folding, reclining, sliding and rotating of the vehicle seat, and a controller including a processor and a memory provided to process the image data, wherein the controller identifies height information of a driver based on processing of the image data, and identifies a getting-on position based on the height information of the driver and existing height information stored in the memory and controls the seat motor to shift the vehicle seat to the identified getting-on position.
In some embodiments, the controller may be configured to identify a getting-off position based on the identified getting-on position and the height information of the driver and control the seat motor to shift the vehicle seat to the identified getting-off position.
In some embodiments, the identifying of the getting-off position may include calculating a getting-off distance based on the height information of the driver and identifying the getting-off position based on the getting-off distance and the identified getting-on position.
In some embodiments, the sensing device may further include a sensor provided to detect whether the driver is seated on the vehicle seat, and the controller may control the seat motor to shift the vehicle seat to the identified getting-on position when it is identified that the driver is seated on the vehicle seat.
In some embodiments, the vehicle may further include an input device provided to adjust the position of the vehicle seat, wherein the sensing device may further generate position data including the position of the vehicle seat, and the controller, when a position manipulation of the vehicle seat is received from the input device, may determine whether to identify the position of the vehicle seat as the getting-on position based on the position data of the vehicle seat depending on the position manipulation and existing getting-on positions stored in the memory.
In some embodiments, the controller may be configured to identify the position of the vehicle seat as the getting-on position in response to a case where a difference between an average value of the existing getting-on positions stored in the memory and the position of the vehicle seat is smaller than the getting-off distance.
In some embodiments, the controller may be configured to determine whether to identify the position of the vehicle seat as the getting-on position based on whether the vehicle corresponds to a driver getting-off condition in response to a case where a difference between an average value of the existing getting-on positions stored in the memory and the position of the vehicle seat is larger than the getting-off distance.
In some embodiments, the controller may be configured to identify the existing getting-on position as the getting-on position in response to the vehicle corresponding to the driver getting-off condition.
In some embodiments, the controller may be configured to identify drivers getting on the vehicle based on the processing of the image data, and store height information and the identified getting-on position for each of the identified drivers.
In some embodiments, the controller may be configured to generate the getting-on positions as metadata for time depending on the identified drivers.
In accordance with an aspect of the disclosure, a vehicle control method includes obtaining image data toward an outer lateral direction of a driver seat of a vehicle by a camera, identifying height information of a driver based on processing of the image data, identifying a getting-on position based on the height information of the driver and existing height information stored in the memory, and controlling a seat motor to shift a vehicle seat to the identified getting-on position.

The input device 200 refers to a device that receives an input signal for controlling the position of the vehicle seat 100 by the driver.
As described above, the input device 200 is provided at a predetermined position of the interior of the vehicle 1 or of the vehicle seat 100, and may include various types. For example, the input device 200 may be provided as a lever, a jog shuttle type, or a hard key type. The input device 200 may also include various types of electronic devices capable of automatically controlling the vehicle seat 100 and the position of each component of the vehicle seat 100 through the sensor 520 when the driver is seated.
The seat motor 400 provided to control the position of the vehicle seat 100 may be provided inside the vehicle 1 or within the vehicle seat 100. As an example, the seat motor 400 may be a sensorless brushless DC motor.
Specifically, the BLDC motor may include a rotor made of a magnet or a magnetic material, and refers to a DC (direct current) motor using a characteristic in which a rotor rotates as a stator generates a magnetic field while rotating. Therefore, the BLDC motor does not require a separate driver to drive the motor.
The controller 300 according to the disclosure may control a power supply (not shown) installed inside the vehicle 1 in response to a signal from the input device 200. Accordingly, the power supply applies input power for driving the seat motor 400, thereby rotating the seat motor 400.
The seat motor 400 may implement a movement including at least one of folding, reclining, sliding and rotating of the vehicle seat 100. However, the disclosure is not limited thereto, and movements of components included in the vehicle seat 100 may be implemented. As an example, the seat motor 400 truly implement a movement to the front and/or rear of the vehicle seat 100 depending on a position control of the vehicle seat 100 of the driver from the input device 200, and may implement a movement to the front and/or rear of the vehicle seat 100 depending on a position control signal received from the controller 300.
In order to control the position of the vehicle seat 100, the position of the vehicle seat 100 needs to be detected first. In general, in order to detect the position of the vehicle seat 100, the separate sensor 520 such as a hall sensor may be provided. However, the disclosure is not limited thereto. As another embodiment, the sensor 520 is not an additional sensor, for example, may refer to a device (riot shown) that senses the position of the vehicle seat 100 through a current flowing in the seat motor 400. That is, the sensor 520 may refer to a conventionally known sensor and/or device capable of identifying the position of the vehicle seat 100, and a sensor and/or device capable of identifying the position of the vehicle seat 100, which will be developed in the future, may also be applied.
The sensor 520 may also include, for example, a sensor to detect whether the driver is seated on the driver seat 110. That is, the sensor 520 may generate position data including the position of the vehicle seat 100, and may detect whether the driver is seated on the driver seat 110.
The camera 510 may be installed to have a field of view of an outer side of the driver seat 110 of the vehicle 1 to photograph the side of the driver seat 110 of the vehicle 1, thereby obtaining image data of the side of the driver seat 110 of the vehicle 1. The camera 510 is also installed to have a field of view of a side of the passenger seat 120 of the vehicle 1 to photograph the side of the passenger seat 120 of the vehicle 1, thereby obtaining image data of the side of the passenger seat 120 of the vehicle 1. However, the disclosure is not limited thereto. As another embodiment, the camera 510 may include, for example, at least one of the first camera for obtaining side direction image data of the driver seat 110 and the second camera for obtaining side direction image data of the passenger seat 120.
The image data may include information about various objects on the side of the vehicle 1. The objects may include, for example, people, buildings, vehicles, horizons, street lamps, roadside trees, etc., and are not limited thereto.
The camera 510 may include a plurality of lenses and an image sensor. The image sensor may include a plurality of photo diodes to convert light into an electric signal, and the plurality of photo diodes may be arranged in a two-dimensional matrix.
More specifically, the camera 510 may include a graphic processor to process image data, and thus may distinguish between the objects included in the image data based on the processing of the obtained image data. For example, the camera 510 may recognize the driver or a person approaching from a side direction of the driver seat 110 and recognize a face of a person by processing the image data.
The camera 510 may be electrically connected to the controller 300. For example, the camera 510 may be connected to the controller 300 through a vehicle communication network NT, or may be with the controller 300 through a hard wire. The front camera 510 may transmit the image data of an outer side of the driver seat 110 or passenger seat 120 of the vehicle 1 to the controller 300.
The controller 300 may process the image data received from the camera 510 and may identify another vehicle or a pedestrian or a cyclist or a lane (marker distinguishing between lanes) or a free space, that is located on a side of the vehicle 1, from the image data.
In particular, the controller 300 may identify a person approaching from an outer direction of the main body 2 of the vehicle 1 based on the processing of image data. The controller 300 may also recognize the face of the approaching person based on the processing of the image data and may calculate height information of the person. However, the disclosure is not limited thereto.
Recognizing the face of a person based on the processing of the image data may be, for example, determining whether the approaching person is the driver by input of the image data through the facial recognition algorithm learned through an artificial neural network. However, the disclosure is not limited thereto. As another embodiment, the controller 300 may, based on the image data, perform a facial recognition of a person by applying a facial recognition program developed previously, or by applying a facial recognition program to be developed in the future.
The controller 300 may include the processor 310 and the memory 320.
The processor 310 may process image data received from the camera 510 and sensing data received from the sensor 520, and may output a control signal for controlling the drive device 60, the vehicle seat 100, and the like. For example, the processor 310 may include an image processor, a digital signal processor (DSP), and/or a micro control unit (MCU).
The processor 310 may identify objects around the vehicle 1 (e.g., another vehicle, a pedestrian, a cyclist, etc.), a lane on a road, and a free space based on the image data received from the camera 510.
The processor 310 may, based on the image data, identify relative positions (distance from the vehicle and angle to the driving direction) and classification (e.g., whether the object is another vehicle, a pedestrian, or a cyclist, etc.) of lateral objects of the vehicle 1. The processor 310 may also perform facial recognition when the identified lateral object is a person based on the image data to identify whether the person is a registered driver. The processor 310 may also identify a distance between the identified lateral object and the camera 510.
The processor 310 may recognize a person and identify height information of the recognized person, based on the processing of the image data received from the camera 510. More specifically, the processor 310 may identify a lateral object (a person) and identify a distance between the lateral object and the camera 510, based on the processing of the image data received from the camera 510. The processor 310 may also perform face recognition of the lateral object to calculate angle information to a position where the face of the lateral object is recognized with respect to the same plane as a vertical height of the camera 510 from the ground.
In summary, the processor 310 may recognize a person, which is the lateral object, based on the image data and may calculate angle information between the face of the person and the same plane as the vertical height of the camera 510 from the around. Accordingly, the processor 310 may calculate height information of the person based on the angle information and the distance to the person.
The vehicle 1 may further include touch sensors provided on handles attached to the doors 71 and 72. That is, the sensor 520 may further include touch sensors provided on the handles of the doors 71 and 72 of the vehicle 1 to detect a human touch.
Accordingly, the processor 310 may generate a control signal for controlling image data obtainment of the camera 510 when a human touch is recognized on the handle of the door 71 or 72 of the vehicle 1, thereby minimizing the power normally consumed by the camera 510. However, the disclosure is not limited thereto.
The processor 310 may calculate height information of driver based on the processing of the image data received from the camera 510 and identify a getting-on position based on the height information of driver and height information of driver previously stored in the memory. Herein, the getting-on position may refer to, for example, the position of the vehicle seat 100 when the driver gets on the vehicle 1 and the vehicle 1 travels. In addition, the getting-off position, which will be described later, may refer to, for example, a position in which the vehicle seat 100 is shifted to the rear for convenience of getting off of the driver when the driver gets off the vehicle 1. However, the disclosure is not limited thereto.
More specifically, because the height information of the driver might be stored in the memory 320 if the driver got on the vehicle in the past, the processor 310 may know that the most recently identified height information of the driver based on the present may be the height information of the driver previously stored in the memory.
Accordingly, the processor 310 may determine necessity of adjusting the getting-on position of the driver by comparing the most recently identified height information of the driver based on the present, height information of the driver identified based on the processing of image data currently received from the camera 510, and the previously stored height information of driver, and may readjust the getting-on position depending on the necessity. However, the disclosure is not limited thereto. This may, for example, be to readjust an optimized getting-on position of the driver depending on a heel height of a shoe of the driver and be to adjust the getting-on position suitable for a changed driver when the driver changes.
The processor 310 may also identify the getting-off position based on the identified getting-on position and the height information of the driver.
More specifically, the processor 310 may calculate a getting-off distance based on the height information of the driver and identify the getting-off position based on the getting-off distance and the getting-on position. That is, because, for example, more adaptive convenience to the driver may be provided by a change in the getting-off distance depending on the height information of the driver, it may be understood that the larger the height of the driver, the larger the getting-off distance may be proportionally increased.
When a control signal for manipulating the position of the vehicle seat 100 is received from the input device 200, the processor 310 may receive the position data including the position of the vehicle seat 100 depending on a position manipulation from the sensor 520.
Also, when the control signal for manipulating the position of the vehicle seat 100 is received from the input device 200, the processor 310 may determine whether to identify the position of the vehicle seat 100 shifted depending on the position manipulation received from the input device 200 as the getting-on position, based on the received position data including the position of the vehicle seat 100 and the previously stored getting-on positions. Herein, the previously stored getting-on positions may include, for example, records of getting-on positions before the driver manipulates the position of the vehicle seat 100 through the input device 200 and getting-on positions of the driver who has got on the vehicle 1 in the past. Because this is described assuming that there is only one driver of the vehicle 1, when there is a plurality of drivers of the vehicle 1, d may refer to past getting-on position records identified for each driver distinguished through a variety of height information of drivers or facial recognition. That is, when there is a plurality of drivers, it may be understood that the previously stored getting-on positions may include getting-on position records identified as each driver got on the vehicle 1 in the past.
Determining whether the processor 310 identifies the shifted position of the vehicle seat 100 as the getting-on position may be made by, for example, when the position of the vehicle seat 100 is manipulated through the input device 200 of the driver, determining whether the manipulation is performed by an intention of the driver.
The processor 310 may also identify the position of the vehicle seat 100 shifted by the manipulation inputted to the input device 200 as the getting-on position, further based on a getting-off condition of vehicle 1.
The memory 320 may store a program and/or data for the processor 310 to process the image data, a program and/or data for the processor 310 to process the sensing data, and a. program and/or data for the processor 310 to generate a driving signal and/or a braking signal and/or a steering signal.
The memory 320 may store the image data received from the camera 510 and/or the sensing data received from the sensor 520, and may store the processing result of the image data and/or radar data of the processor 310.
The memory 320 may include not only a volatile memory such as S-RAM and D-RAM, but also a non-volatile memory such as flash memory, read-only memory (ROM), and erasable programmable read-only memory (EPROM).
That is, the memory 320 may store the result of data processing by the processor 310, and may transmit the stored data processing result to the processor 310 in response to a request of the processor 310.
More specifically, the memory 320 may store the getting-on position and the getting-off position identified based on the height information of the driver as well as the height information of the driver identified by the processor 310. The memory 320 may also store the height information and the identified getting-on position for each driver depending on the identified drivers.
In addition, the memory 320 may generate and store driver-specific metadata regarding the getting-on position and height information for each driver according to the passage of time depending on the identified drivers. Based on this, the processor 310 recognizes an object approaching from a side of the vehicle 1 as a person and identifies as a driver, and may access a past getting-on position history, a past getting-off position history, and a past height information history based on the metadata generated for each driver.
As such, the controller 300 may generate a control signal for moving a position of the seat motor 400 to the identified getting-on position or getting-off position based on the image data received from the camera 510 and/or the sensing data received from the sensor 520.
Hereinafter, with reference to the drawings, the vehicle 1 according to an embodiment will describe in detail the calculation of height information of the driver and identification of the getting-on position and the getting-off position.
Referring to
A mounting height 511 of the camera 510 may be calculated on the basis of vehicle manufacturing information, for example, and may be determined depending on a position where the camera 510 is mounted when the camera 510 is mounted on the vehicle 1.
The controller 300 may calculate angle information between the recognized face or height region of the driver based on the processing of the image data and a plane parallel to the ground at a height a at which the camera 510 is installed. More specifically, the controller 300 may, based on the processing of the image data, calculate angle information based on a table about angles depending on the height region occupied by the driver in the image data obtained by the camera 510 depending on the distance where the driver is recognized. However, the disclosure is not limited thereto.
Accordingly, the controller 300 may identify the height information of the driver based on the calculated angle information.
The height information of the driver may be, for example, calculated through Equation 1 below.
H=a+(b×tan θ) [Equation 1]
Herein, H may refer to the identified height information of the driver, the constant a may refer to the same value as the mounting height 511 of the camera 510, h may refer to the distance between the driver and the camera 510 identified by the controller 300, and θ may refer to the angle information between the plane of the height of the camera 510 parallel to the around and the tip of the head of the driver or face recognition position. However, the disclosure is not limited thereto.
Therefore, referring to Equation 1 above, it may be understood that the height information of the driver may be derived by adding the height 511 of the camera 510 and the distance 513 between the tip of the head of the driver and the height of the camera.
A getting-on position 100a may refer to, for example, the position of the vehicle seat 100 when the driver gets on the vehicle 1 and/or when the vehicle 1 is in a driving state, and a getting-off position 100b may refer to, for example, a position in which the position of the vehicle seat 100 is shifted to the rear for the convenience in getting off of the driver when the vehicle 1 corresponds to the driver getting-off condition.
The controller 300 may identify the getting-on position 100a based on the height information of the driver identified based on the processing of the image data and the height information of the driver identified in the past. The height information of the driver identified in the past may refer to, for example, height information of the driver most recently identified based on a current time point.
More specifically, the controller 300 may compare the identified driver height information with previously identified driver height information, and when the height information is the same or within an error range, may identify existing getting-on position as the getting-on position 100a. The error range may refer to, for example, a case in which a difference between the height information of the driver and the previously identified height information of the driver is less than a preset value, and the preset value is an empirically or experimentally calculated value, and may be a value derived in consideration of convenience of the driver or a value directly changed by the driver.
The controller 300 may compare the identified driver height information with the previously identified driver height information, and when the height information is different or out of the error range, may identify the getting-on position 100a based on the existing getting-on position and the currently identified driver height information. In this case, identifying of the getting-on position may be identified based on Equation 2 below.
Herein, X may refer to the getting-on position 100a, Xp may refer to a recent getting-on position based on the present, H may refer to the identified height information of the driver, and Hp may refer to height information of the driver corresponding to the recent getting-on position based on the present. However, the disclosure is not limited thereto.
More specifically, as illustrated in
Referring to Equation 2 above, for example, in a case where the height information of the driver is 180 cm while the height information of the driver in the past is 178 cm, it may be understood that the controller 300 may identify the getting-on position 100a of the identified driver by about 1.011 times the past getting-on position. That is, it may be understood that as the height of the driver increases compared to the past record, the getting-on position may be shifted to the rear. In addition, it may be understood that the getting-on position may be shifted to the front, depending on a case where the height of the driver becomes smaller compared to the past record. Herein, the numerical values are exemplary values, and the getting-on position 100a may be corrected by further calculating an arbitrary constant.
The controller 300 may identify a getting-off distance 100c based on the height information of the driver. More specifically, the getting-off distance 100c may be identified based on Equation 3 below.
Herein, L may refer to the getting-off distance 100c, in and n may be numerical values inputted arbitrarily by a user or parameters calculated empirically or experimentally, and H may refer to the identified height information of the driver. However, the disclosure is not limited thereto.
As an example, as values calculated through experimental data, when an average height of an adult male is 170 cm, a default value of 5 cm for the most convenient getting-off distance for the driver may be applied to the parameter, and when the height of the driver is 180 cm, 5 may be applied to in and 170 may be applied to n. Accordingly, the controller 300 may identify the getting-off distance 100c of about 5.3 cm. Therefore, as the height of the identified driver increases, the getting-off distance 100c may increase.
Accordingly, the controller 300 may identify the getting-off distance 100c based on the identified height information of the driver, and may calculate the getting-off position 100b based on the identified getting-on distance 100a and the getting-off distance 100c. More specifically, the getting-off position 100b may be identified by summing the identified getting-on distance 100a and the getting-off distance 100c. However the disclosure is not limited thereto.
When the getting-on position 100a and the getting-off position 100b of the driver are identified and when the vehicle 1 corresponds to the getting-on condition of the driver, the controller 300 may shift the position of the vehicle seat 100 to the getting-on position 100a by generating a control signal for controlling the seat motor 400.
As an example, the getting-on condition of the driver may be a case in which the driver is seated on the vehicle seat 100 through the sensor 520 and/or a case in which the vehicle 1 is started. However, the disclosure is not limited thereto, and the getting-on condition may further include whether the driver is wearing a seat belt.
Referring to
More specifically, because vertical widths of the doors 71 and 72 are limited when the vehicle seat 100 is high, it may cause inconvenience to the driver when the driver gets off Accordingly, it may be understood that not only the getting-off position 100b described above as an example is applied to the getting-off position, but also the height may be set to be low, and not only the getting-on position 100a described above as an example is applied to the getting-on position, but also the height may be stored.
Hereinafter, when the driver of the vehicle 1 according to an embodiment manipulates the position of the vehicle seat 100 through the input device 200, determining whether the manipulation may correspond to an intention of the driver and readjusting of the getting-on position will be described in detail.
Specifically, a conventional seat memory system may store the getting-on position and/or getting-off position of the vehicle based on the manipulation when the position of the seat is manipulated through the input device, regardless of whether the position of the seat is in the getting-on position or the getting-off position, thereby adjusting the position of the seat to wrong getting-on position and getting-off position, which may cause inconvenience of re-manipulation and suspicion of malfunction to the driver.
In order to solve the above problems, the controller 300 included in the vehicle 1 according to an embodiment may, when the driver manipulates the vehicle seat 100 through the input device 200, obtain the position of the vehicle seat 100 shifted by the manipulation from the sensor 520.
The controller 300 may also determine whether to identify the seat position shifted depending on the manipulation of the driver as the getting-on position 100a based on the position of the vehicle seat 100 identified from the sensor 520 and the existing getting-on positions stored in the memory 320. This may be to more accurately identify the intention of the driver by considering an average value of the getting-on positions identified in the past, learning information about the adaptive getting-on position suitable for the driver and comparing the information with the current position. However, the disclosure is not limited thereto.
More specifically, the controller 300 may compare a difference between the average value of the existing getting-on positions stored in the memory 320 and the current position of the vehicle seat 100 with the identified getting-off distance 100c and determine whether to identify the current position of the vehicle seat 100 as the getting-on position 100a.
That is, the controller 300 may identify the current position of the vehicle seat 100 as the getting-on position 100a in response to a case where the difference between the average value of the existing getting-on positions and the position of the vehicle seat 100 is smaller than the identified getting-off distance 100c, which corresponds to the case where the current position of the vehicle seat 100 compared to the average value does not differ by more than the getting-off distance.
The controller 300 may also determine whether to identify the position of the vehicle seat 100 as the getting-on position 100a based on whether the vehicle 1 corresponds to the getting-off condition of the driver in response to a case where the difference between the average value of the existing getting-on positions and the position of the vehicle seat 100 is larger than the identified getting-off distance 100c, which corresponds to a case where the distance to the normally learned (stored) getting-on positions is large.
More specifically, because the case where the difference between the average value of the existing getting-on positions and the position of the vehicle seat 100 is larger than the identified getting-off distance 100c corresponds to an unusual position of the vehicle seat 100, the controller 300 may identify the getting-on position 100a based on whether the unusual position corresponds to the getting-off condition of the driver of the vehicle 1 in order to identify determine the intention of the driver.
The driver getting-off condition may, for example, correspond to at least one of the cases in which the ignition of the vehicle 1 is turned off, the door 71 or 72 of the vehicle 1 is opened, and the seat belt of the vehicle 1 is released. However, the disclosure is not limited thereto.
Accordingly, when the difference between the average value of the existing getting-on positions and the position of the vehicle seat 100 is larger than the identified getting-off distance 100c, the controller 300 may identify the existing getting-on position rather than the current position of the vehicle seat 100 as the getting-on position 100a in response to the vehicle 1 corresponding to the driver getting-off condition. On the contrary, in response to the vehicle 1 not corresponding to the driver getting-off condition, the controller 300 may identify the current position of the vehicle seat 100 as the getting-on position 100a.
Accordingly, the controller 300 may identify the getting-on position 100a by determining the intention of the user based on the driver getting-off condition and the comparison with the current position of the vehicle seat 100 and the average value of the existing getting-on positions.
Although the above has been mainly described for controlling the vehicle seat 100 based on the camera 510 installed toward the outer side of the driver seat 110 of the vehicle 1, it may be understood that the above description may be equally applied to an occupant of the passenger seat 120 by further including an additional camera installed toward an outer side of the passenger seat 120. In addition, it may be understood that the above description is also applicable to the rear seat of the vehicle 1.
