[0086] In order to facilitate passengers to rest more comfortably in the vehicle and avoid unconscious shaking of the head during rest that affects the rest quality or causes neck injury, in an embodiment of the present invention, a neck protection system can be installed on the vehicle seat to protect the head and neck of the passenger.

[0087] Figure 1 FIG. 1 is a schematic diagram of the internal structure of a vehicle according to an embodiment of the present invention. Specifically, Figure 1 As shown, the neck protection system mainly includes: a driving device 11 and two neck protection structures connected to the driving device 11; each neck protection structure includes a telescopic rod 121, a rotating mechanism 122 and a support panel 123; wherein the telescopic rod 121 is connected to the rotating mechanism 122, and the support panel 123 is connected to either the telescopic rod 121 or the rotating mechanism 122.

[0088] Since the occupant's head may shake left and right when resting, the neck protection system can be installed at the headrest position of the vehicle seat, and the two neck protection structures respectively include support panels 123 arranged on both sides of the headrest, so that the occupant's head and neck can be protected from both sides. Figure 2 As shown in FIG, it is a structural diagram of the support panel 123 on one side of the headrest. Figure 2 As shown, the support panel 123 included in one neck protection structure is arranged on one side of the headrest, and the support panel 123 included in the other neck protection structure can be arranged on the other side of the headrest ( Figure 2 not shown).

[0089] In order to meet the needs of passengers, in an embodiment of the present invention, the driving device 11 drives the telescopic rod 121 to extend and / or the rotating mechanism 122 to rotate in response to the control instructions sent by the vehicle system. The telescopic rod 121 extends and retracts, driving the support panel 123 to move in the width direction of the headrest, and the rotating mechanism 122 rotates, driving the support panel 123 to rotate with the telescopic rod 122 as the axis.

[0090] In the embodiment of the present invention, the driving device may include a driving motor, and the vehicle system refers to a system for controlling the neck protection system in the vehicle, such as an ECU (computer control module, electronic control unit), which can send control instructions to the driving device. The control instructions represent instructions for controlling the telescopic rod 121 and / or the rotating mechanism 122, that is, they include control instructions for the rotating mechanism 122 sent by the vehicle system and / or control instructions for the telescopic rod 122 sent by the vehicle system. The position adjustment of the support panel 123 can be achieved by controlling the telescopic rod 121 and / or the rotating mechanism 122. In the embodiment of the present invention, the rotation of the rotating mechanism 122 can drive the support panel 123 to rotate with the telescopic rod 122 as the axis. For example, the rotation method can be as follows. Figure 1 In the middle direction D, the support panel 123 can be rotated from position A to position B. The telescopic rod 121 can be extended to drive the support panel 123 to move in the width direction of the headrest. The moving direction can be as follows: Figure 2 As shown in direction C, the support panel 123 can be closer to or farther away from the headrest.

[0091] It should be noted that, in order to fully utilize the space inside the vehicle, the neck protection system can be installed at the headrest bracket in the embodiment of the present invention. Figure 3 The following is a schematic diagram of the equipment structure in the vehicle. Figure 3 As shown in position 34, it can be used to install a neck support system.

[0092] In one embodiment of the present invention, one end of the telescopic rod 121 is connected to the rotating mechanism 122, and the rotating mechanism 122 is connected to the supporting panel 123. Figure 1 As shown. In this scenario, the other end of the telescopic rod 122 is detachably connected to the headrest bracket of the headrest, so that the neck protection system can be installed at the headrest position. In response to receiving the control instruction for the telescopic rod 122 sent by the vehicle system, the driving device drives the telescopic rod 121 to extend and retract, and the extension and retraction of the telescopic rod 121 can drive the rotating mechanism 122 and the support panel 123 to move simultaneously in the width direction of the headrest. In response to receiving the control instruction for the rotating mechanism 122 sent by the vehicle system, the driving device drives the rotating mechanism 122 to rotate, and when rotating, the rotating mechanism 122 can drive the support panel 123 to rotate with the telescopic rod 121 as the axis.

[0093] In another embodiment of the present invention, one end of the telescopic rod 121 is connected to the support panel 123, and the other end of the telescopic rod 121 is connected to the rotating mechanism 122. In this scenario, the other end of the telescopic rod 122 or the rotating mechanism 122 can be detachably connected to the headrest bracket of the headrest, so that the neck protection system can be installed at the headrest position. In response to receiving a control instruction for the rotating mechanism 122 sent by the vehicle computer system, the driving device drives the rotating mechanism 122 to rotate. When the rotating mechanism 122 rotates, it can drive the telescopic rod 121 and the support panel 123 to rotate about the telescopic rod 121. In response to receiving a control instruction for the telescopic rod 122 sent by the vehicle computer system, the driving device drives the telescopic rod 121 to extend and retract. The extension and retraction of the telescopic rod 121 can drive the support panel 123 to move in the width direction of the headrest.

[0094] It should be noted that in this connection scenario, the neck protection system can be detachably connected to the headrest bracket by connecting one end of the rotating mechanism 122 through the telescopic rod 121, or it can be detachably connected to the headrest bracket through the rotating mechanism 122, or it can be detachably connected to the headrest bracket using other methods, and there is no limitation on this.

[0095] In another embodiment, in order to facilitate the support panel 123 to support the occupant's head and neck, the telescopic rod 121 is arranged at a position close to the headrest of the vehicle seat, and the extension direction of the telescopic rod 121 is parallel to the width direction of the headrest, so that the telescopic rod 121 can drive the support panel 123 to move in the width direction of the headrest when it is extended and retracted. The main surface of the support panel 123 is perpendicular to the width direction of the headrest, so that the shaking of the head can be minimized when the support panel is close to the headrest.

[0096] It should be noted that if Figure 3 As shown, other devices may also be provided in the vehicle, including a camera 31, a window shade 32, and a microphone 33, etc., to provide a more comfortable resting environment for the passengers.

[0097] Figure 4 FIG. 1 is a schematic diagram of the main steps of a control method for a neck protection system according to an embodiment of the present invention. Specifically, Figure 4 As shown, the control method of the neck support system is used to Figure 1-3 The control of the neck protection system shown mainly includes the following steps:

[0098] Step S401: In response to a vehicle neck protection mode activation instruction, the current seat of the corresponding occupant is determined, and image information of the current seat is acquired.

[0099] Among them, the neck protection mode represents a mode for protecting the head and neck of the occupant, that is, a mode for protecting the head and neck of the occupant by the neck protection system in the embodiment of the present invention. After the neck protection mode start instruction is triggered, the occupant in the vehicle who needs head and neck protection can be determined first. Under normal circumstances, the occupants who are preparing to rest or are already resting on the vehicle seat can be the occupants who need to trigger the neck protection mode start instruction, so the corresponding occupant can be determined by identifying the state of the occupant on the vehicle seat; or, the neck protection mode start instruction can include the occupant's information, and the corresponding occupant can be directly determined through the neck protection mode start instruction. After the occupant is determined, the seat he is sitting on, that is, the current seat, can be determined, and then the image information of the occupant on the current seat can be collected.

[0100] It should be noted that in the embodiments of the present invention, image information is used to determine the occupant's current seat posture, and further, to determine the position of the occupant's head when the occupant is in a normal resting position in the current seat. The image information can be captured in real time by a camera, or it can be pre-captured and stored. In the embodiments of the present invention, the method for identifying the position of an occupant in a vehicle seat is not limited.

[0101] In one embodiment, the present invention can trigger the neck support mode activation command in a variety of ways. Specifically, the neck support mode activation command can be received through the vehicle's voice system (e.g., a microphone) or display system (e.g., a central control screen); alternatively, the vehicle can capture occupant image information and identify the occupant's facial features; and the neck support mode activation command is triggered in response to the facial features matching pre-set features.

[0102] When the occupants need to turn on the neck protection mode, they can input voice commands, such as "turn on the neck protection mode", through the voice device in the voice system. The voice device collects the voice command and transmits it to the ECU for identification. After determining the content of the voice command, the neck protection mode start command is triggered. Alternatively, the occupants can also manually input the neck protection mode start command through the display device in the display system. The display device transmits it to the ECU and triggers the neck protection mode start command. Alternatively, the image information of the occupants can be collected by the shooting device, and the facial features of the occupants in the image can be identified. If the facial features of the occupants are identified to match the preset features, it means that the occupants have entered a resting state, and the neck protection mode start command can be triggered. The preset features can be set according to the scene, for example, it can include features such as closed eyes and yawning.

[0103] In another embodiment, when responding to a neck protection mode activation instruction, the embodiment of the present invention can also control other devices in the vehicle in order to improve the rest comfort of the occupants, such as outputting a closing instruction to the vehicle's window system, outputting a closing instruction to the vehicle's audio system, and / or outputting neck protection mode activation information to the vehicle's display system.

[0104] The window system can be used to open or close the windows and the window sunshades. Outputting a close command to the window system closes the windows and / or window sunshades to prevent the outside environment from disturbing the occupants' rest. Outputting a close command to the audio system can turn off the audio equipment to prevent the sound from disturbing the occupants' rest. The display device can display information indicating that the neck support mode is active to inform the occupants of the current neck support system status.

[0105] Step S402: Identify the current head position of the occupant from the image information, obtain the current panel position of the support panel in the neck protection system connected to the current seat, and determine the relative position relationship between the support panel of the neck protection system and the occupant's head in combination with the current head position.

[0106] Among them, the neck protection system connected to the current seat can include two support panels. In this step, the current panel positions of the two support panels can be determined respectively, and then the relative position relationship between the two support panels and the occupant's head can be determined in combination with the current head position.

[0107] The image information includes the occupant's resting posture in the current seat. This image information can be used to identify the position of the occupant's head and neck while resting in the current seat, specifically, the occupant's current head position. To prevent head shaking and potential injury to the head and neck, in embodiments of the present invention, the current head position can be the specific position of the occupant's head outline relative to the seat's headrest. Specifically, the current head position can be the height and width of the head outline relative to the headrest. For example, the head width can be determined based on the outer edges of the two ears, and the head height can be determined based on the height of the ears.

[0108] It should be noted that the image information may be an image of the occupant in a normal resting state in the current seat, such as an image of the occupant facing forward, so as to determine a more accurate current head and neck position.

[0109] Since the neck protection system is usually in the initial state when the neck protection mode is turned off, the position of the support panel in the neck protection system can be a preset initial position at this time. Therefore, after determining the current head position of the occupant, the relative position relationship between the support panel connected to the current seat and the occupant's head can be determined in combination with the initial position.

[0110] It should be noted that in an embodiment of the present invention, a coordinate system can be established in advance, such as a coordinate system can be established based on the position of the center point of the headrest, so that the user's current head position and the initial position of the support panel can be marked by the coordinate system, and then the relative position relationship can be determined.

[0111] In the embodiment of the present invention, the support panel of the neck support system can move along the extension direction of the telescopic rod and can rotate in the rotation direction of the rotation mechanism. Therefore, the extension direction of the telescopic rod can be determined as the first direction, and the rotation direction of the rotation mechanism can be determined as the second direction. Then, the support panel can move in the first direction and rotate in the second direction. The first direction also refers to the width direction of the headrest, such as Figure 2 As shown in C, the second direction also represents the rotation direction with the telescopic rod as the axis, such as Figure 1 As shown in D in the middle. In order for the support panel to provide maximum protection for the occupant's head and neck, the support panel generally needs to be close to the occupant's head position and a larger area of ​​the support panel is maintained on both sides of the occupant's head. Therefore, the support panel generally needs to be adjusted in both the first direction and the second direction.

[0112] The relative position relationship determined in the embodiment of the present invention may include a relative distance and a relative angle. Specifically, this step may be specifically performed as follows: determining the occupant's ear position based on the current head position, and determining the distance between the ear position and the main surface of the support panel as the relative distance; determining the occupant's head center point based on the current head position, and determining the vertical connection line between the head center point and the rotation center axis of the rotation mechanism as the first connection line; obtaining the panel center point of the support panel, and determining the vertical connection line between the panel center point and the rotation center axis as the second connection line; and determining the angle between the first connection line and the second connection line as the relative angle.

[0113] Since the ears are located on the outside of the head, the relative distance can be the distance between the occupant's ear position and the support panel, such as the minimum vertical distance between the outer contour of the occupant's ear and the main surface of the support panel. The relative angle can be the angle between the center point of the occupant's head and the vertical line between the center point of the support panel and the rotation center axis of the rotating mechanism. For example, with the center axis of the rotating mechanism as a reference, the vertical line between the center point of the head and the center axis is the first line, and the vertical line between the center point of the support panel and the center axis is the second line. The angle between the first line and the second line after being mapped to the same plane perpendicular to the center axis can be the relative angle. The rotation center axis of the rotating mechanism can be specifically the center axis of the telescopic rod.

[0114] It should be noted that the method for determining the relative position relationship in the embodiment of the present invention is not limited. For example, the relative angle can also be determined based on the center point of the occupant's ear and the center point of the support panel.

[0115] Step S403: Obtain the occupant's neck protection parameters, determine the adjustment strategy of the support panel based on the relative position relationship, generate a control instruction according to the adjustment strategy and output it to the driving device of the neck protection system to adjust the support panel.

[0116] Among them, the protection needs of different occupants may be different. The occupant's neck protection parameters represent the position of the support panel that is suitable for the occupant, and may specifically include a distance parameter and an angle parameter. The distance parameter may represent the desired distance between the occupant's ear position and the support panel, and the angle parameter may represent the desired angle between the occupant's head center point and the vertical line perpendicular to the rotation center axis of the rotation mechanism relative to the support panel center point. In an embodiment of the present invention, the neck protection parameters adjusted for different users after the neck protection mode is turned on can be recorded, so the occupant's neck protection parameters can be obtained from the historical records in this step. At the same time, in an embodiment of the present invention, universal neck protection parameters can also be pre-set. In this step, when the occupant's neck protection parameters are not included in the historical records, the universal neck protection parameters can be obtained to determine them as the occupant's neck protection parameters.

[0117] The occupant's neck protection parameters are equivalent to the adjustment targets of the support panel, so the adjustment strategy of the support panel can be determined based on this and the relative position relationship, that is, the strategy of adjusting the support panel from the relative position to the position represented by the neck protection parameters.

[0118] Specifically, in an embodiment of the present invention, the adjustment strategy may include a distance adjustment parameter and an angle adjustment parameter, wherein the distance adjustment parameter represents a parameter for adjusting the support panel in a first direction, and the angle adjustment parameter represents a parameter for adjusting the support panel in a second direction. The method for determining the adjustment strategy in this step may be performed as follows: obtaining the occupant's distance parameter, and calculating the moving direction and moving distance of the support panel based on the relative distance; obtaining the occupant's angle parameter, and calculating the rotation direction and rotation angle of the support panel based on the relative angle; and determining the moving direction, moving distance, rotation direction, and rotation angle as the adjustment strategy for the support panel, wherein the distance adjustment parameter includes the moving direction and moving distance, and the angle adjustment parameter includes the rotation direction and rotation angle.

[0119] For example, the difference between the relative distance and the distance parameter can be calculated. The value of this difference can represent the distance the support panel has moved, and the positive or negative sign of the difference can indicate the direction of movement of the support panel. For example, if the difference is "-2cm," the corresponding adjustment strategy is to move 2cm closer to the headrest. For another example, the difference between the relative angle and the angle parameter can be calculated. The value of this difference can represent the rotation angle of the support panel, and the positive or negative sign of the difference can indicate the direction of rotation of the support panel. For example, if the angle difference is "-10 degrees," the corresponding adjustment strategy can be to move 10 degrees clockwise along the central axis of the connecting mechanism.

[0120] It should be noted that in the embodiment of the present invention, the calculation principles of the relative position relationship and the neck protection parameters need to be consistent so that the adjustment strategy can be accurately determined to avoid errors or mistakes in determining the adjustment strategy due to inconsistent calculation principles of the two.

[0121] After determining the adjustment strategy, corresponding control instructions can be generated based on this. The control instructions can be output to the driving device in the neck protection system, so that the driving device can execute the corresponding control instructions to adjust the telescopic rod and / or rotation mechanism, thereby driving the adjustment of the support panel.

[0122] Specifically, the control strategy may include strategies in two dimensions: the first direction and the second direction. Therefore, in this step, the movement parameters of the support panel in the first direction and the rotation parameters of the second direction can be determined according to the adjustment strategy, and the movement instructions corresponding to the first direction and the rotation instructions corresponding to the second direction can be generated respectively.

[0123] It should be noted that, in order to make the support plate more safely adjusted, in an embodiment of the present invention, the movement instruction and the rotation instruction can be executed separately. For example, the movement instruction can be executed first, and then the rotation instruction can be executed. Specifically, it can be executed as follows: based on the movement parameters, a movement instruction corresponding to the first direction is generated, and the movement instruction is output to the driving device; in response to the support panel being adjusted to the position corresponding to the movement instruction, a rotation instruction corresponding to the second direction is generated based on the rotation parameters, and the rotation instruction is output to the driving device.

[0124] The support panel can be moved to the position corresponding to the movement instruction by monitoring the position of the support panel in real time, and the rotation instruction is output after it is determined that the support panel is adjusted to the position corresponding to the movement instruction.

[0125] It should be noted that in the embodiment of the present invention, the two support panels in the neck protection system are located on both sides of the headrest. These two support panels can be controlled simultaneously or separately. When the two support panels are adjusted separately, steps S402 and S403 can be executed in sequence to adjust the two support panels separately. Since the positions of the support panels on both sides are usually consistent, when the two support panels are adjusted simultaneously, after determining the adjustment strategy for one support panel, the movement direction in the adjustment strategy can be reversed to obtain the adjustment strategy for the other support panel, and then the support panels on both sides can be adjusted.

[0126] In another embodiment, in an embodiment of the present invention, a neck protection mode off command can be triggered in scenarios such as when an occupant is recovering from rest. The neck protection mode off command represents an instruction to restore the support panel to its initial position. Therefore, in response to the vehicle's neck protection mode off command, the current position of the support panel can be obtained, and a restoration strategy for the support panel can be determined based on the preset initial position, and a restoration command can be generated. The restoration command is then output to the drive device of the neck protection system to adjust the support panel to its initial position. The initial position is pre-set, and the principle for determining the restoration strategy in the embodiment of the present invention is the same as the principle for determining the adjustment strategy in step S403. The corresponding restoration command and principle are also the same as the principle for generating the control command in step S403, and will not be further elaborated here.

[0127] In one embodiment, due to an early warning during vehicle driving, the support panel may cause secondary injuries to the occupants. Therefore, in an embodiment of the present invention, after receiving the vehicle's driving early warning instruction, the status of the neck protection mode in the vehicle can be queried; if the neck protection mode is on, the neck protection mode off instruction can be triggered to restore the support panel to its initial position.

[0128] In an embodiment of the present invention, a neck protection system is installed at the headrest position of the vehicle seat. The support panels in the neck protection system are arranged on both sides of the headrest. The neck protection mode can be turned on when the occupant is resting. That is, the support panels of the neck protection system are automatically adjusted according to the occupant's head position in the current seat, so that the support panels are close to both sides of the headrest according to the occupant's needs, which can protect the occupant's head and neck. In this way, when the occupant is resting while the vehicle is driving, the support panels can provide support and protection for the occupant's head and neck, avoiding the problem that the occupant's head will be affected by the shaking of the vehicle unconsciously, resulting in reduced rest quality or neck injury, and effectively providing the occupant with an intelligent and comfortable rest experience.

[0129] Furthermore, in the embodiment of the present invention, a camera 51, a window system 52, a voice system 53, an audio system 54, an operating system 55, a display device 56, and an ECU 57 can be provided in the vehicle to form a rest assist system in combination with the neck support system 10, so as to provide the occupants with a more comfortable resting environment. Figure 4 The control method shown.

[0130] like Figure 5 Figure 2 shows a schematic diagram of the control relationships within a vehicle. The voice system receives audio through a microphone and transmits it to the ECU for identification. The system then controls the vehicle's devices based on the identified commands. A camera can capture video and images, such as those of a passenger in a vehicle seat, and transmit them to the ECU for identification. This information can be used to identify the passenger's facial features and determine their posture, head, and neck position. The window system receives open or close signals to control the opening or closing of windows and window shades, effectively shielding passengers from sunlight and providing a comfortable resting environment. The audio system receives open or close signals to control the audio system on and off, or to activate its active noise cancellation mode, providing a comfortable and distraction-free resting space. The display device displays content (such as operating system menus and the status of the neck support mode). The operating system receives user input through display devices such as the central control screen.

[0149] In an embodiment of the present invention, a neck protection system is installed at the headrest position of the vehicle seat. The support panels in the neck protection system are arranged on both sides of the headrest. The neck protection mode can be turned on when the occupant is resting. That is, the support panels of the neck protection system are automatically adjusted according to the occupant's head position in the current seat, so that the support panels are close to both sides of the headrest according to the occupant's needs, which can protect the occupant's head and neck.

[0158] Furthermore, an embodiment of the present invention provides a vehicle that implements the control method of the neck support system provided in the embodiment of the first aspect or includes the control device of the neck support system provided in the embodiment.

[0159] The following describes the technical scenarios to which the technical solutions provided by the embodiments of the present invention are applicable based on the system architecture on which the technical solutions provided by the embodiments of the present invention rely.

[0160] Figure 7 An exemplary system architecture 700 is shown, to which a control method for a neck brace system or a control device for a neck brace system according to an embodiment of the present invention may be applied.

[0161] like Figure 7 As shown, the vehicle system architecture 700 may include various systems, such as a driving control system 701, a power system 702, a sensor system 703, a control system 704, an auxiliary lane change system 705, one or more peripheral devices 706, a power supply 707, a computer system 708, and a user interface 709. The control method of the neck protection system provided in the embodiment of the present invention may be implemented by interacting with the above-mentioned systems, or may be implemented by controlling the above-mentioned systems through external devices or by operating the above-mentioned systems through a robot driving the vehicle. Optionally, the vehicle system architecture 700 may include more or fewer systems, and each system may include multiple components. In addition, each system and component of the vehicle system architecture 700 may be interconnected by wire or wirelessly. The vehicle system architecture 700 may also include the neck protection system in the embodiment of the present invention.

[0162] The vehicle system architecture 700 includes a driving control system 701, which can be in a fully or partially automated driving mode. For example, the driving control system 701 can automatically control the vehicle's movement based on control signals or control instructions without human interaction, or through interaction with an external device or a robot driving the vehicle.

[0163] The power system 702 may include components that provide power and movement for the vehicle. For example, the power system 702 may include an engine, an energy source, a transmission, wheels, tires, etc. The engine may be an internal combustion engine, an electric motor, an air compression engine, or a combination of other types of engines, such as a hybrid engine consisting of a gasoline engine and an electric motor, or a hybrid engine consisting of an internal combustion engine and an air compression engine. The engine converts the energy source into mechanical energy and provides it to the transmission. Examples of energy sources may include gasoline, diesel, other petroleum-based fuels, propane, other compressed gas-based fuels, ethanol, solar panels, batteries, and other sources of electricity. The energy source may also provide energy to other systems of the vehicle. In addition, the transmission may include a gearbox, a differential, a drive shaft, a clutch, etc.

[0164] The sensor system 703 may include sensors for sensing the surrounding environment of the vehicle (such as sensors for sensing whether there are obstacles around) and pressure sensors for sensing whether there are passengers on the seats. For example, a positioning system (the positioning system may be a global positioning system (GPS) system, or a Beidou system or other positioning system), a radar, a laser rangefinder, an inertial measurement unit (IMU), and a camera. The positioning system can be used to locate the geographic location of the vehicle. The IMU is used to sense the position and orientation changes of the vehicle based on inertial acceleration. In one embodiment, the IMU may be a combination of an accelerometer and a gyroscope. The radar may use radio signals to sense objects in the surrounding environment of the vehicle. In some embodiments, in addition to sensing objects, the radar may also be used to sense the speed and / or direction of travel of the object.

[0165] To detect environmental information and objects outside the vehicle, a camera or the like can be positioned at an appropriate location outside the vehicle. For example, to capture an image of the vehicle's side environment, a camera can be located on the vehicle's side rearview mirror. The camera can be a static or video camera.

[0166] The control system 704 may include software systems for implementing vehicle driving control, such as a system for analyzing the vehicle's surroundings, a system for pre-tensioning seatbelts, a system for route planning, a system for avoiding obstacles, and a vision system for image analysis. The control system 704 may also include hardware systems such as a throttle, a steering wheel system, a seatbelt system, an airbag system, and peripheral devices (such as projection equipment and displays). Furthermore, the control system 704 may include additional or alternative components beyond those shown and described. Alternatively, some of the components shown above may be reduced.

[0167] Furthermore, as described above, the control system 704 can further implement a portion of the control method for the neck protection system described above. In response to a vehicle neck protection mode activation command, the control system 704 determines the current seat of the corresponding occupant and obtains image information of the current seat; identifies the occupant's current head position from the image information, obtains the current panel position of the support panel in the neck protection system connected to the current seat, and determines the relative positional relationship between the support panel of the neck protection system and the occupant's head based on the current head position; obtains the occupant's neck protection parameters, determines an adjustment strategy for the support panel based on the relative positional relationship, generates a control command based on the adjustment strategy, and outputs it to the drive device of the neck protection system. The process of controlling the vehicle's autonomous driving primarily involves inputting the autonomous driving command into the driving control system 701, which then controls the vehicle's driving mode.

[0168] In addition, the control system 704 can also interact with external sensors, other autonomous driving devices, other computer systems, or users through peripheral devices 706. Peripheral devices 706 may include wireless communication systems, onboard computers, microphones and / or speakers, cameras, and projectors.

[0169] In some embodiments, peripheral devices 706 provide a means for a user of control system 704 to interact with a user interface. For example, an onboard computer can provide information to the user of the vehicle. The user interface can also operate the onboard computer to receive user input. The onboard computer can be operated via a touch screen. In other cases, peripheral devices can provide a means for communicating with other devices located within the vehicle. For example, a microphone can receive audio (e.g., voice commands or other audio input) from the user of the control system. Similarly, a speaker can output audio to the user of the control system.

[0170] A wireless communication system can communicate wirelessly with one or more devices directly or via a communication network. For example, a wireless communication system can communicate using a cellular network, WiFi, or wireless local area network (WLAN), or can directly communicate with devices using infrared links, Bluetooth, or ZigBee. Other wireless protocols, such as various autonomous driving communication systems, are also used.

[0171] The power supply 707 can provide power to various components of the vehicle. The power supply 707 can be a rechargeable lithium-ion or lead-acid battery.

[0172] Some or all of the functions implementing vehicle control for ramp-entry scenarios are controlled by computer system 708. Computer system 708 may include at least one processor that executes instructions stored in a non-transitory computer-readable medium such as a memory. Computer system 708 provides the control system with executable code for implementing vehicle control for ramp-entry scenarios.

[0173] The processor can be any conventional processor, such as a commercially available central processing unit (CPU). Alternatively, the processor can be a dedicated device such as an application specific integrated circuit (ASIC) or other hardware-based processor. Those skilled in the art will appreciate that the processor, computer, or memory can actually include multiple processors, computers, or memories that may or may not be stored in the same physical housing. For example, the memory can be a hard drive or other storage medium that is located in a housing that is different from the computer. Therefore, reference to a processor or computer will be understood to include reference to a collection of processors or computers or memories that may or may not operate in parallel. Different from using a single processor to perform the steps described herein, each of some components such as a steering assembly and a deceleration assembly can have its own processor that only performs the determination related to the function of the component.

[0174] The user interface 709 is used to provide information to or receive information from a user of the vehicle. Optionally, the user interface 709 may include one or more input / output devices within the set of peripheral devices 706, such as a wireless communication system, an onboard computer, a microphone, and a speaker.

[0175] It should be understood that the above components are only examples. In actual applications, components in the above modules or systems may be added or deleted according to actual needs. Figure 7 It should not be understood as limiting the embodiments of the present application.

Various programs and data required for the operation of the system 800 are also stored in the RAM 803. The CPU 801, ROM 802, and RAM 803 are connected to each other via a bus 804. An input / output (I / O) interface 805 is also connected to the bus 804.

The communication section 809 performs communication processing via a network such as the Internet. A drive 810 is also connected to the I / O interface 805 as needed. A removable medium 811, such as a magnetic disk, an optical disk, a magneto-optical disk, or a semiconductor memory, is installed in the drive 810 as needed, so that a computer program read therefrom can be installed in the storage section 808 as needed.

[0179] In particular, according to the embodiments disclosed in the present invention, the processes described above with reference to the flowcharts can be implemented as computer software programs.

In the present invention, a computer-readable storage medium can be any tangible medium containing or storing a program that can be used by or in conjunction with an instruction execution system, apparatus, or device. In the present invention, a computer-readable signal medium can include a data signal propagated in baseband or as part of a carrier wave, carrying computer-readable program code.
