DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS
To describe technical solutions of embodiments of the present application more clearly, the accompanying drawings required for describing the embodiments will be briefly described below. Obviously, the accompanying drawings described below show merely some of the examples or embodiments of the present application, and those of ordinary skill in the art would also have applied the present application to other similar scenarios according to these accompanying drawings without involving any creative effort. Unless obvious from the language context or otherwise illustrated, the same reference numerals in the figures represent the same structure or operation.
As shown in the present application and the claims, unless the context expressly indicates otherwise, the words “a” , “an” , “said” , and/or “the” do not specifically refer to the singular, but may also include the plural.  Generally, the terms “include” and “comprise” only suggest that the expressly identified steps and elements are included, but these steps and elements do not constitute an exclusive list, and the method or device may further include other steps or elements.
In the description of the present application, it should be understood that orientations or position relationships indicated by orientation terms such as “front, rear, up, down, left, and right” , “transverse, vertical, perpendicular, and horizontal” , and “top and bottom” are generally based on orientations or position relationships shown in the drawings and are merely for ease of description of the present application and simplification of the description, rather than indicating and implying that the apparatuses or elements referred to must have a specific orientation or be constructed and operated in a specific orientation if there is no explanation to the contrary, and therefore cannot be construed as limiting the scope of protection of the present application. The orientation terms “interior and exterior” refer to inside and outside relative to a contour of each component itself.
For ease of description, spatial relative terms such as “over ... ” , “above ... ” , “on upper surface of ... ” , and “on ... ” may be used here to describe a spatial position relationship between one device or feature and another device or feature as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations of the device in use or operation, in addition to the orientation of the device  described in the figure. For example, if devices in the figure are inverted, the device described as “above” or “over” another device or structure will later be positioned as “below” or “under” another device or structure. Therefore, the exemplary term “above ... ” may include both “above ... ” and “below ... ” orientations. The device may also be positioned in other different ways (rotated by 90 degrees or in other orientations) , and the spatial relative descriptions used here are interpreted accordingly.
In addition, it should be noted that, the use of terms such as “first” and “second” to define parts is merely for ease of facilitating differentiation of the corresponding parts. If not otherwise stated, the above terms have no special meanings and thus cannot be construed as limiting the scope of protection of the present application. Furthermore, although the terms used in the present application are selected from well-known common terms, some of the terms mentioned in the description of the present application may have been selected by the applicant according to his or her determination, and the detailed meaning thereof is described in the relevant section described herein. Furthermore, the present application must be understood, not simply by the actual terms used but also by the meanings encompassed by each term.
It should be understood that when a component is said to be “located on another component” , “connected to another component” , “coupled to another component” , or “in contact with another component” , it may be directly located on the another component, connected or coupled to the  another component, or in contact with the another component, or there may be an intervening component. In contrast, when a component is said to be “directly located on another component” , “directly connected to another component” , “directly coupled to another component” , or “in direct contact with another component” , there is no intervening component. Similarly, when a first component is said to be “in electrical contact with” or “electrically coupled to” a second component, there is an electrical path between the first component and the second component that allows the flow of current. The electrical path can include a capacitor, coupled inductors, and/or other components that allow the flow of current, even without direct contact between conductive components.
A flowchart is used in the present application to illustrate the operations performed by the system according to the embodiments of the present application. It should be understood that the above or following operations are not necessarily performed exactly in order. Instead, the various steps may be processed in reverse order or simultaneously. In addition, other operations are added to these processes, or a certain step or several operations are removed from these processes.
The embodiments of the present invention describe an adjustment system and method for a safety intervention of a cockpit of a vehicle, a safety intervention system for a vehicle, and a vehicle.
FIG. 1 is a schematic diagram of the composition of an adjustment  system for a safety intervention of a cockpit of a vehicle according to an embodiment of the present application.
As shown in FIG. 1, the adjustment system 100 for a safety intervention of a cockpit of a vehicle (which may also be referred to as adjustment system 100 for short) includes an occupant observation unit 111, an exterior observation unit 112, and an adjustment unit 101.
In some embodiments, the occupant observation unit 111 is configured to obtain in-vehicle occupant observation information, i.e., observation information of an occupant inside a vehicle. The exterior observation unit 112 is configured to obtain collision information corresponding to an obstacle outside the vehicle. The obstacle outside the vehicle includes, for example, an exterior obstacle in a region adjacent to the vehicle. The occupant observation information includes, for example, poses, body types, or weight data of occupants. The weight data is obtained, for example, by means of a mass sensor mounted on a seat.
Various components of the adjustment system for a safety intervention of a cockpit of a vehicle are connected or coupled to each other over an in-vehicle interconnect network, such as a CAN bus, for the transmission of data and instructions.
The adjustment unit 101 is configured to adjust a seat safety system based on the collision information and the occupant observation information, to position the occupant in a safe pose, where the seat safety system includes  a seat with an integrated seat belt system.

FIG. 4 is a schematic diagram of a process of adaptively adjusting a buckle of a seat safety system according to an embodiment of the present application.
As shown in FIG. 4, the seat safety system includes a buckle 403 which is adapted to the seat belt and located on a first side of a cushion 402. The buckle adjustment unit 116 is configured to adaptively adjust an inclination angle of the buckle as an angle of the seat backrest 401 is adjusted, to adapt a safety belt buckle to a pose of an occupant. Specifically, the adjustment is performed, for example, in adjustment directions A1 and A2 in FIG. 4.
In some embodiments, the collision information includes a collision probability, and the exterior observation unit 112 is configured to determine the collision probability based on the data of the exterior obstacle and motion  data of a self-vehicle.
When the collision probability is greater than a first threshold, the adjustment unit adjusts the seat safety system to position the seat safety system in a target constrained state. The target constrained state includes, for example, an initial constrained state, and more specifically, the initial constrained state may include an initial stroke position of the seat and an initial backrest angle of the seat.
In some embodiments, the collision information further includes a relative speed and/or a collision overlap rate. The adjustment unit 101 adjusts a seat safety system based on the relative speed and/or the collision overlap rate, to position the seat safety system in a corresponding target constrained state. The target constrained state may include the initial constrained state. Alternatively, different target constrained states may be set according to different relative speeds and collision overlap rates, and accordingly, there may be different adjustment parameters for the stroke position of the seat and the backrest angle of the seat.
In some embodiments, intervals corresponding to several thresholds may also be set, and the seat safety system is adjusted depending on an interval corresponding to the threshold into which different relative speeds and collision overlap rates fall, so that the seat safety system is in the corresponding target constrained state.
In some embodiments, when the collision probability is greater than  the first threshold, the adjustment unit 101 adjusts the seat belt system on the seat to place a seat belt in a tensioned state and hold the occupant tightly against a seat back, that is to say, playing the role of giving, by an active seat belt, an early warning to hold the occupant tightly against the seat.
In some embodiments, the adjustment system for a safety intervention of a cockpit of a vehicle further includes a current state obtaining unit. The current state obtaining unit is configured to obtain current state data of the seat.
