[0040] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
[0041] Figure 1 is a plan view of a vehicle according to some embodiments of the present invention.
[0042] like Figure 1 As shown, the vehicle 1 may include at least one of a belt pretensioner (PT) 110, a passenger airbag (PAB) 120, a driver airbag (DAB) 130, front impact detection sensors (FIS) 140-1 and 140-2, an airbag control unit (ACU) 150, an occupant status detection sensor 160, a radar sensor 170, and a camera sensor 180.
[0043] The occupant condition detection sensor 160 may include at least one of an occupant detection sensor (ODS) for detecting a seat position of an occupant and a type of the occupant, a seat traction position sensor (STPS), and a buckle detection sensor (B / S).
[0044] The type of the occupant may be a normal male, a short female, or an infant, but is not limited thereto.
[0045] The ACU 150 may control the driver airbag 130 , the passenger airbag 120 , and the seatbelt pretensioner 110 based on a detection result of at least one of the front collision detection sensors 140 - 1 and 140 - 2 and the occupant condition detection sensor 160 .
[0046] Figure 2 is a control block diagram of a vehicle according to some embodiments of the present invention.
[0047] refer to Figure 2 The vehicle 1 may include a safety device 210, a camera sensor 180 for detecting obstacles around the vehicle 1, a radar sensor 170 for detecting obstacles around the vehicle 1, and a controller 200, wherein the controller 200 is configured to: predict a collision state of the vehicle 1 and a collision position of the vehicle 1 by means of the camera sensor 180 and the radar sensor 170; determine whether to control the safety device 210 in response to the prediction result based on at least one of the type of the vehicle 1, the collision speed, the seat position of the occupant, whether the occupant is wearing a seat belt, the gender of the occupant, whether the occupant is an infant, and the body shape of the occupant; and control the safety device 210 according to whether the safety device 210 is controlled.
[0048] The safety device 210 may include a seatbelt pretensioner 110 , a passenger airbag 120 , and a driver airbag 130 .
[0049] Although not shown, the safety device 210 may further include a front side airbag (FSAB), a rear side airbag (RSAB), and a rear airbag (RAB).
[0050] The controller 200 may receive external obstacle detection information outside the vehicle 1 through the camera sensor 180 and the radar sensor 170 via a controller area network (CAN).
[0051] The controller 200 may receive information on the relative speed and the collision time sensed by the radar sensor 170 through a controller area network (CAN).
[0052] When the relative speed between the vehicle 1 and the external obstacle is greater than a predetermined speed and the estimated collision time is less than a predetermined time, the controller 200 may predict that the vehicle 1 will collide.
[0053] The controller 200 may receive occupant seat position information, occupant type information, and seat belt wearing information through the occupant condition detection sensor 160 .
[0054] The controller 200 may receive the overlap rate information of the vehicle 1 through a controller area network (CAN).
[0055] Here, the overlap ratio information may be a ratio greater than or equal to 0% and less than or equal to 100%.
[0056] Some embodiments of the present invention describe receiving information related to the vehicle 1 via the CAN, but are not limited thereto.
[0057] When it is predicted that the vehicle 1 will collide, the controller 200 may determine whether the overlap rate detected by the camera sensor 180 is greater than or equal to 0% and less than 50%, or greater than or equal to 50% and less than or equal to 100%.
[0058] When it is predicted that the vehicle 1 will collide, the controller 200 may calculate the difference between the absolute value of the acceleration detected by the front collision detection sensor 140-1 installed in the direction of the driver's seat and the absolute value of the acceleration detected by the front collision detection sensor 140-2 installed in the direction of the passenger seat.
[0059] When it is predicted that the vehicle 1 will collide, the controller 200 may determine the acceleration detected by the ACU 150 .
[0060] For example, when the overlap rate detected by the camera sensor 180 is greater than or equal to 0% and less than 50%, the difference between the absolute value of the acceleration detected by the front collision detection sensor 140-1 installed in the direction of the driver's seat and the absolute value of the acceleration detected by the front collision detection sensor 140-2 installed in the direction of the passenger seat is greater than a first value, and the acceleration detected by the ACU is greater than a second value, the controller 200 can predict that the collision position of the vehicle 1 is in the direction of the driver's seat.
[0061] For example, when the overlap rate detected by the camera sensor 180 is greater than or equal to 50% and less than or equal to 100%, the difference between the absolute value of the acceleration detected by the front collision detection sensor 140-1 installed in the direction of the driver's seat and the absolute value of the acceleration detected by the front collision detection sensor 140-2 installed in the direction of the passenger seat is less than a third value, and the acceleration detected by the ACU is less than a fourth value, the controller 200 can predict that the collision position of the vehicle is in the direction of the passenger seat.
[0062] To determine whether to control the safety device 210 , the controller 200 may reflect the difference in collision performance according to the difference in platform or in-vehicle specifications of each type of vehicle 1 .
[0063] The controller 200 may determine whether the occupant is a normal male or a short female and whether the occupant is a baby based on the result detected by the occupant condition detection sensor 160 .
[0064] When there are two or more occupants in the vehicle 1 , the controller 200 may determine the seat position of each occupant, whether each occupant wears a seat belt, and the gender and body type of each occupant based on the results detected by the occupant condition detection sensor 160 .
[0065] The controller 200 may control the seatbelt pretensioner 110 and transmit a control signal for controlling at least one of the passenger airbag 120 and the driver airbag 130 to the ACU 150 .
[0066] The controller 200 may determine a deployment speed of at least one of the seatbelt pretensioner 110 , the passenger airbag 120 , and the driver airbag 130 , and may transmit the deployment speed information to the ACU 150 .
[0067] The deployment speed may be a collision speed at which the airbag expands in a fixed wall collision in a specific area to prevent injury to an occupant when the airbag is controlled.
[0068] For example, when the collision speed of the vehicle 1 is greater than or equal to 9 mph and less than or equal to 14 mph and the occupant is not wearing a seat belt, the controller 200 can control at least one of the passenger airbag 120, the driver airbag 130, the front side airbag (FSAB), the rear side airbag (RSAB) and the rear airbag (RAB) based on the occupant's seat position.
[0069] More specifically, the controller 200 may control at least one of the passenger airbag 120 , the driver airbag 130 , the front side airbag (FSAB), the rear side airbag (RSAB), and the rear airbag (RAB) through the ACU 150 .
[0070] For example, when the collision speed of the vehicle 1 is 11 miles per hour and the occupant is wearing a seat belt, the controller 200 may control the seat belt pretensioner 110 based on the seat position of the occupant.
[0071] For example, when the collision speed of the vehicle 1 is 14 miles per hour and the occupant is wearing a seat belt, based on the seat position of the occupant, the controller 200 can control the seat belt pretensioner 110 and control at least one of the passenger airbag 120, the driver airbag 130, the front side airbag (FSAB), the rear side airbag (RSAB) and the rear airbag (RAB).
[0072] The controller 200 may be implemented as a memory (not shown) storing data related to an algorithm for controlling the operation of components in the vehicle 1 or a program for reproducing the algorithm, and a processor (not shown) for performing operations by utilizing the data stored in the memory. In this case, the memory and the processor may be implemented as separate chips, respectively. Alternatively, the memory and the processor may be implemented as a single chip.
[0073] The storage unit (not shown) may correspond to a memory storing the above information and the following information, and may be implemented as at least one of a nonvolatile storage device such as a cache, a ROM (Read Only Memory), a PROM (Programmable ROM), an EPROM (Erasable Programmable ROM), an EEPROM (Electrically Erasable Programmable ROM), and a flash memory, a volatile storage device such as a RAM (Random Access Memory), and a storage medium such as an HDD (Hard Disk Drive) and a CD-ROM, but is not limited thereto.
[0074] Figure 3 is a table for determining whether to control a safety device of a vehicle according to some embodiments of the present invention.
[0075] Figure 3 A table is shown of actual experiments conducted by combining various situations in which the collision speed of vehicle 1 is greater than or equal to 7 mph and less than or equal to 14 mph, the occupants are in the driver seat and the front passenger seat, the occupants are normal males or short females, and the seat positions of the occupants are the front position, the middle position, and the rear position, and based on whether the occupants wear seat belts, the safety device 210 is not operated, the airbag is operated, the seat belt pretensioner 110 is operated, and both the airbag and the seat belt pretensioner 110 are operated.
[0076] The vehicle 1 can analyze a variety of injury combinations for each vehicle type, and determine whether to control the safety device 210 and determine the deployment speed of the safety device 210 through actual experiments in the order of a sled test and an actual vehicle test.
[0077] Figure 4is a table for determining whether to control a safety device according to a collision speed of a vehicle according to some embodiments of the present invention.
[0078] Although typically, in the same manner regardless of vehicle type, the frontal safety device is not operated in the event of a 10 mph fixed wall frontal collision, and in a 14 mph fixed wall frontal collision, all frontal safety devices are controlled to operate, the vehicle 1 according to some embodiments of the present invention can determine whether to control the safety device based on the collision speed of each vehicle type and the situation in which the occupant is wearing or not wearing a seat belt.
[0079] For example, when the collision speed of the vehicle 1 is less than or equal to 7 miles per hour and the occupant is not wearing a seat belt, the vehicle 1 may control both the DAB (driver airbag) and the PAB (passenger airbag) not to operate.
[0080] For example, when the collision speed of the vehicle 1 is greater than or equal to 9 mph and less than or equal to 14 mph, and the occupant is not wearing a seat belt, the vehicle 1 can control at least one of the DAB (driver airbag) and the PAB (passenger airbag) to operate based on the seat position of the occupant.
[0081] For example, when the collision speed of the vehicle 1 is greater than or equal to 14 miles per hour and the occupant wears a seat belt, the vehicle 1 may control at least one of a DAB (driver airbag) and a PAB (passenger airbag) to operate.
[0082] For example, when the collision speed of the vehicle 1 is 11 miles per hour and the occupant is wearing a seat belt, the vehicle 1 may control the operation of the seat belt pretensioner 110 based on the seat position of the occupant.
[0083] The seat belt pretensioner 110 may have the following functions: when the seat belt is normally operated, the seat belt pulled by the occupant according to his own weight is wound; when the vehicle collides, a part of the seat belt is forcibly wound.
[0084] Figure 5 is a flow chart of a vehicle control method according to some embodiments of the present invention.
[0085] The vehicle 1 may detect whether there is an obstacle outside the vehicle 1 and determine a collision state ( 310 ).
[0086] More specifically, the vehicle 1 may receive obstacle detection information detected by the camera sensor 180 and the radar sensor 170. In addition, the vehicle 1 may receive relative speed information and collision time information through the radar sensor 170.
[0087] The vehicle 1 may determine whether a relative speed between the vehicle 1 and the external obstacle is greater than a predetermined speed ( 320 ).
[0088] When the relative speed between the vehicle 1 and the external obstacle is greater than a predetermined speed, the vehicle 1 may determine whether a predicted collision time between the vehicle 1 and the external obstacle is less than a predetermined time ( 330 ).
[0089] When the predicted collision time between the vehicle 1 and the external obstacle is less than a predetermined time, the vehicle 1 may determine whether the collision position between the vehicle 1 and the external obstacle is in the direction of the driver's seat or in the direction of the passenger seat ( 340 ).
[0090] For example, when the overlap rate detected by the camera sensor 180 is greater than or equal to 0% and less than 50%, the difference between the absolute value of the acceleration detected by the front collision detection sensor 140-1 installed in the direction of the driver's seat and the absolute value of the acceleration detected by the front collision detection sensor 140-2 installed in the direction of the passenger seat is greater than a first value, and the acceleration detected by the ACU is greater than a second value, the controller 1 can predict that the collision position of the vehicle 1 is in the direction of the driver's seat.
[0091] For example, when the overlap rate detected by the camera sensor 180 is greater than or equal to 50% and less than or equal to 100%, the difference between the absolute value of the acceleration detected by the front collision detection sensor 140-1 installed in the direction of the driver's seat and the absolute value of the acceleration detected by the front collision detection sensor 140-2 installed in the direction of the passenger seat is less than a third value, and the acceleration detected by the ACU is less than a fourth value, vehicle 1 can predict that the collision position of vehicle 1 is in the direction of the passenger seat.
[0092] The vehicle 1 may determine whether the collision position between the vehicle 1 and the external obstacle is in the direction of the driver's seat or the direction of the passenger's seat, and may execute an algorithm for controlling the safety device 210 by reflecting the determination result ( 350 ).
[0093] The vehicle 1 may determine the deployment speed of the safety device 210 according to the result of executing the algorithm, and determine whether the safety device 210 is operating.
[0094] The vehicle 1 may control the safety device 210 based on the deployment speed and whether the safety device 210 is operating ( 360 ).
[0095] Figure 6 is a flow chart for determining a vehicle collision location according to some embodiments of the present invention.
[0096] The vehicle 1 may determine overlapping rate information of obstacles detected by the camera sensor 180 of the vehicle 1 ( 410 ).
[0097] For example, when the overlap rate of the obstacles is greater than or equal to 0% and less than 50%, the vehicle 1 can determine that the obstacle exists in the left front of the vehicle 1 and predict the collision position in the direction of the driver's seat. When the overlap rate of the obstacles is greater than or equal to 50% and less than or equal to 100%, the vehicle 1 can determine that the obstacle exists in the right front of the vehicle 1 and predict the collision position in the direction of the passenger seat.
[0098] The vehicle 1 may calculate a difference between an absolute value of acceleration detected by the front collision detection sensor 140-1 installed in the direction of the driver's seat and an absolute value of acceleration detected by the front collision detection sensor 140-2 installed in the direction of the passenger seat (420).
[0099] More specifically, when the difference between the absolute value of the acceleration detected by the front collision detection sensor 140-1 installed in the direction of the driver's seat and the absolute value of the acceleration detected by the front collision detection sensor 140-2 installed in the direction of the passenger seat is greater than a first value, the vehicle 1 can determine that the acceleration detected by the front collision detection sensor 140-1 installed in the direction of the driver's seat is greater, and can determine that the collision position is in the direction of the driver's seat.
[0100] Here, the first value may be a positive number.
[0101] More specifically, when the difference between the absolute value of the acceleration detected by the front collision detection sensor 140-1 installed in the direction of the driver's seat and the absolute value of the acceleration detected by the front collision detection sensor 140-2 installed in the direction of the passenger seat is less than a third value, the vehicle 1 can determine that the acceleration detected by the front collision detection sensor 140-2 installed in the direction of the passenger seat is greater, and can determine that the collision position is in the direction of the passenger seat.
[0102] Here, the third value may be a negative number.
[0103] The vehicle 1 may determine the acceleration detected by the ACU 150 ( 430 ).
[0104] More specifically, when the acceleration detected by ACU 150 is greater than the second value, vehicle 1 can determine that the collision position is in the direction of the driver's seat, and when the acceleration detected by ACU 150 is less than the fourth value, vehicle 1 can determine that the collision position is in the direction of the passenger seat.
[0105] Here, the second value may be a positive number, and the fourth value may be a negative number.
[0106] Figure 7 and Figure 8 is a flow chart of an algorithm for a vehicle according to some embodiments of the present invention.
[0107] Vehicle 1 may determine whether there is an occupant in vehicle 1 and whether there is a baby in vehicle 1 ( 501 ).
[0108] When there is an occupant in vehicle 1 but the occupant is not an infant, vehicle 1 may determine whether the occupant is a short female ( 502 ).
[0109] Here, the short female may refer to an occupant whose body size is smaller than that of an occupant of a predetermined size.
[0110] When there is no short female in the vehicle 1 , the vehicle 1 may determine whether the occupant is wearing a seat belt ( 503 : 503 a ).
[0111] When the occupant is wearing a seat belt, the vehicle 1 may determine whether the occupant is located in a front row position of a seat in the vehicle 1 ( 504 ).
[0112] When the occupant is located in the front row of the seat in vehicle 1, vehicle 1 can determine whether the acceleration is greater than the A value, and when the occupant in vehicle 1 is not located in the front row of the seat in vehicle 1, vehicle 1 can determine whether the acceleration is greater than the C value (505 and 506).
[0113] When the acceleration is less than the A value and less than the C value, the vehicle 1 may control the safety device 210 not to operate ( 507 ).
[0114] When the occupant is located in the front row of the seat in vehicle 1, when the acceleration is greater than the A value, vehicle 1 can again determine whether the acceleration is greater than the B value. When the occupant is not located in the front row of the seat in vehicle 1, when the acceleration is greater than the C value, vehicle 1 can again determine whether the acceleration is greater than the D value (508 and 509).
[0115] When the acceleration is greater than the B value and greater than the D value, the vehicle 1 may control the seat belt pretensioner 110 to operate and control the airbag to operate according to the seat position of the occupant (510).

[0133] Some embodiments of the present invention may be implemented in the form of a recording medium storing instructions executable by a computer. The instructions may be stored in the form of program code, and when executed by a processor, a program module may be created to perform the operations of the disclosed embodiments. The recording medium may be implemented as a computer-readable recording medium.
[0134] The computer-readable recording medium includes various recording media in which instructions that can be decrypted by a computer are stored.

[0135] As is apparent from the above, in some embodiments of the present invention, the speed and strategy of safety devices are determined based on the type of vehicle, the seating position of the occupants in the vehicle, the age of the occupants, and the gender of the occupants, thereby improving collision safety performance.
[0136] More specifically, typically, in the development of safety device deployment performance, the deployment speed and deployment criteria of the safety device are applied under the same conditions for all vehicle types, resulting in the difference in different collision performance for each vehicle type not being reflected in the deployment performance, and it is difficult to confirm the effect of improving occupant injuries based on the occupant condition. However, in some embodiments of the vehicle of the present invention, the body platform and interior specifications of each vehicle type can be reflected in the deployment process of the safety device during a collision, and based on the type of occupant (e.g., whether it is an infant, male or female), the occupant condition, and the location of the vehicle collision, the safety device deployment speed and deployment strategy that can minimize occupant injuries can be classified and determined. For this reason, improvements in collision safety performance can be expected in the event of an actual accident.
[0137] In addition, analysis can be performed based on various conditions, and standards for minimizing occupant injuries can be developed through sled tests and actual vehicle tests, thereby establishing safety device deployment performance development standards.
[0138] While the invention has been described in detail with reference to exemplary embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
