Description

Technical Field

[0001] This application relates to the field of vehicle control technology, and in particular to a control method, device, on-board controller and storage medium for vehicle collisions. Background Technology

[0002] With the continuous increase in car ownership, the risk of vehicle collisions is also increasing. When a collision occurs, the vehicle's safety mechanisms can automatically open doors or windows to allow occupants to exit the vehicle. However, opening doors or windows can potentially trigger secondary accidents; for example, an electric vehicle traveling to the side or rear might collide with the door after it has opened. Therefore, while existing vehicle safety mechanisms facilitate the rescue of occupants, they also pose a significant risk of causing secondary accidents. Summary of the Invention

[0003] In view of this, embodiments of this application provide a method, device, vehicle controller, and storage medium for controlling vehicle collisions, which can provide convenience for people inside rescue vehicles while reducing the risk of secondary accidents.

[0004] The first aspect of this application provides a method for controlling a vehicle collision, including:

[0005] When a vehicle collision is detected, the body shape information of the people inside the vehicle is obtained;

[0006] Based on the body shape information, determine the door opening and / or window opening of the vehicle;

[0007] Control the vehicle doors to open according to the door opening degree, and / or control the vehicle windows to open according to the window opening degree.

[0008] In this embodiment, when a vehicle collision is detected, the body size information of the occupants is acquired. Based on this information, the opening degree of the vehicle doors and / or windows is determined. Finally, the doors and / or windows are controlled to open according to this determined opening degree. This design allows for reasonable control of the door and / or window opening based on the occupants' body size, thereby facilitating rescue while reducing the risk of secondary accidents. For example, if the occupants are small, the doors can be opened only slightly, allowing for easy evacuation. Furthermore, compared to opening the doors more fully, this method also reduces the risk of secondary accidents.

[0009] In one implementation of this application, determining the vehicle door opening degree and / or window opening degree based on the body shape information may include:

[0010] For any door of the vehicle, obtain the first body shape information of the person inside the vehicle who is closest to the door; based on the first body shape information, determine the opening range of the door.

[0011] For any window of the vehicle, obtain the second body shape information of the person inside the vehicle who is closest to that window; based on the second body shape information, determine the opening range of the window.

[0012] In one implementation of this application, whether a collision has occurred can be detected in the following way:

[0013] Acquire the collision signal output by the vehicle's airbag system;

[0014] If the collision signal passes the verification, it is determined that the vehicle has collided.

[0015] Furthermore, the collision signal includes a collision location signal, which indicates the location where the vehicle collided; determining the vehicle door opening and / or window opening based on the body shape information may include:

[0016] The location where the vehicle collided is determined based on the collision location signal;

[0017] If the collision occurs on the side of the vehicle, the door opening and / or window opening of the vehicle are determined based on the vehicle's body shape information.

[0018] If the collision occurs at a location other than the side, the door opening and / or window opening of the vehicle are determined to be the preset minimum value.

[0019] Furthermore, the collision signal includes a collision level signal, which indicates the severity of the collision involving the vehicle; determining the vehicle door opening and / or window opening based on the vehicle size information may include:

[0020] The severity of the collision is determined based on the collision level signal.

[0021] If the severity of the collision involving the vehicle is not high-risk, then the opening degree of the vehicle's doors and / or the opening degree of its windows are determined based on the vehicle's body size information.

[0022] If the severity of the collision involving the vehicle is classified as high-risk, then the opening degree of the vehicle's doors and / or windows is set to the preset maximum value.

[0023] In one implementation of this application, obtaining the body shape information of the people inside the vehicle may include:

[0024] Acquire pressure signals from pressure sensors located under the seats of the vehicle;

[0025] Based on the pressure signal, determine the body shape information of the people inside the vehicle;

[0026] or,

[0027] Acquire images of occupants inside the vehicle captured by a camera installed inside the vehicle;

[0028] Based on the images of the people inside the vehicle, determine the body shape information of the people inside the vehicle.

[0029] In one implementation of this application, the step of detecting a vehicle collision may further include:

[0030] Obtain weather information sent via cloud servers;

[0031] The visibility of the vehicle's surroundings is determined based on the weather information;

[0032] If the visibility is less than a set threshold, then the vehicle's rear fog lights are activated.

[0033] A second aspect of this application provides a control device for a vehicle collision, comprising:

[0034] The body shape information acquisition module is used to acquire the body shape information of the people inside the vehicle when a vehicle collision is detected.

[0035] An opening degree determination module is used to determine the door opening degree and / or window opening degree of the vehicle based on the body shape information.

[0036] The vehicle control module is used to control the vehicle doors to open according to the door opening degree, and / or control the vehicle windows to open according to the window opening degree.

[0037] A third aspect of this application provides an on-board controller, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the vehicle collision control method provided in the first aspect of this application.

[0038] A fourth aspect of this application provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the vehicle collision control method provided in the first aspect of this application.

[0039] The fifth aspect of this application provides a computer program product that, when run on an in-vehicle controller, causes the in-vehicle controller to execute the vehicle collision control method provided in the first aspect of this application.

[0040] It is understood that the beneficial effects of the second to fifth aspects mentioned above can be found in the relevant descriptions in the first aspect mentioned above, and will not be repeated here. Attached Figure Description

[0045] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application can also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail. Furthermore, in the description of this application and the appended claims, the terms "first," "second," "third," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance.

[0046] Vehicle driving safety is a key focus for those skilled in the art. To facilitate the rescue of occupants during a vehicle collision, vehicle safety mechanisms can automatically control the opening of doors or windows upon impact. However, controlling the opening of doors or windows can also potentially trigger serious secondary accidents. To address this issue, this application provides a method, device, on-board controller, and storage medium for controlling vehicle collisions, which can facilitate the rescue of occupants while reducing the risk of secondary accidents. For more specific technical details regarding the implementation of this application's embodiments, please refer to the method embodiments described below.

[0047] Please see Figure 1This application illustrates a vehicle collision control method provided in an embodiment, comprising:

[0048] 101. When a vehicle collision is detected, obtain the body shape information of the people inside the vehicle;

[0049] It should be understood that the execution subject of the control method provided in this application embodiment can be various types of vehicle controllers. All steps of the control method can be executed by one vehicle controller or by multiple different vehicle controllers working together. This application embodiment does not impose any restrictions on the type and number of vehicle controllers used.

[0050] When a vehicle collision occurs, collision signals can be detected by components such as touch sensors, distance sensors, or airbag systems, thus confirming that a collision has taken place. Once a collision is confirmed, the body shape information of the occupants is acquired. This information may include, but is not limited to, height, weight, shoulder width, side width, chest or waist circumference, body type, etc. There are various methods for acquiring this body shape information; for example, it can be pre-recorded and saved for each occupant, or it can be detected using devices installed in the vehicle (such as pressure sensors or cameras).

[0051] If there are multiple people in the vehicle, one approach is to obtain the body size information of each person and then combine this information to determine the opening degree of each door / window. Alternatively, one approach is to obtain only the body size information of the largest person among all the passengers and then combine this information to determine the opening degree of each door / window. This approach is designed so that as long as the opening degree of the doors / windows is sufficient to transfer the largest person, the need to transfer all passengers can be met.

[0052] In one implementation of this application, whether a collision has occurred can be detected in the following way:

[0053] (1) Obtain the collision signal output by the vehicle's airbag system;

[0054] (2) If the collision signal passes the verification, it is determined that a collision has occurred.

[0055] Many vehicles are now equipped with airbag systems. When a collision occurs, the airbag system outputs a corresponding collision signal. This collision signal undergoes a verification process to prevent false alarms. Once the collision signal passes verification, a collision can be confirmed. The specific verification methods for the collision signal can be found in existing technologies and will not be elaborated upon here.

[0056] In one implementation of this application, obtaining the body shape information of the people inside the vehicle may include:

[0057] (1) Acquire pressure signals from pressure sensors located under the seats of the vehicle;

[0058] (2) Based on the pressure signal, determine the body shape information of the people inside the vehicle.

[0059] In one implementation, pressure sensors can be installed under each seat in the vehicle. When a person sits on a seat, the pressure sensor under that seat will be compressed and generate a corresponding pressure signal. The magnitude of this pressure signal can be used to estimate the person's weight, and further estimate other body shape information such as shoulder width and side width. Alternatively, body shape information can be determined based on the magnitude of the pressure signal, for example, classifying body shape into low, lower-middle, medium, and high levels. In practice, the pressure sensors can be connected to the vehicle's intelligent cockpit controller. The intelligent cockpit controller can acquire the person's body shape information and transmit this information to other onboard controllers (such as the body controller, body domain controller, window controller, or door control modules, etc.) via communication lines provided by the vehicle (e.g., CAN bus or LIN bus).

[0060] In another implementation of this application embodiment, obtaining the body shape information of the people inside the vehicle may include:

[0061] (1) Acquire images of people inside the vehicle captured by a camera installed inside the vehicle;

[0062] (2) Determine the body type information of the people inside the vehicle based on the images of the people inside the vehicle.

[0063] In another implementation, a camera at a suitable angle can be installed inside the vehicle to capture images of the occupants. Then, facial recognition can be performed on these images to identify each person in the image, and body size analysis can be performed to obtain the body shape information of each person inside the vehicle. The specific methods for facial recognition and body size analysis of the occupants are existing technologies and will not be elaborated upon here.

[0064] 102. Based on body shape information, determine the vehicle door opening and / or window opening;

[0065] After obtaining the body shape information of the occupants in the vehicle, the vehicle door opening and / or window opening can be determined based on this information. There are three implementation methods: (1) determining the vehicle door opening based on body shape information; (2) determining the vehicle window opening based on body shape information; and (3) determining both the vehicle door opening and window opening based on body shape information. In practice, appropriate door and window openings corresponding to different body shapes can be pre-defined and recorded. For example, a slender body shape corresponds to a 35% door opening and a 60% window opening, a normal body shape corresponds to a 50% door opening and an 80% window opening, and an obese body shape corresponds to a 75% door opening and a 100% window opening, and so on. Then, by obtaining the body shape information of the occupants in the vehicle, the corresponding door and / or window openings can be found.

[0066] In one implementation of this application, determining the vehicle door opening and / or window opening based on body shape information may include:

[0067] (1) For any door of the vehicle, obtain the first body shape information of the person closest to that door inside the vehicle; and determine the opening range of that door based on the first body shape information.

[0068] (2) For any window of the vehicle, obtain the second body shape information of the person closest to that window inside the vehicle; and determine the opening range of that window based on the second body shape information.

[0069] Vehicles typically have four doors: a front left door, a front right door, a rear left door, and a rear right door. For a given door, the body shape information (represented by "first body shape information") of the person closest to that door can be obtained to determine the door's opening range. For example, for the front left door, the closest person is usually the driver. The driver's body shape information can be obtained using pressure sensors in the driver's seat, and the opening range of the front left door can be determined based on this information. Similarly, for the rear right door, the closest person is usually a passenger in the right rear seat. The corresponding passenger's body shape information can be obtained using pressure sensors in the right rear seat, and the opening range of the rear right door can be determined based on this information.

[0070] Similarly, vehicles typically have four windows: a front left window, a front right window, a rear left window, and a rear right window. For a given window, the body shape information (represented as second body shape information) of the person closest to that window can be obtained to determine the window's opening range. For example, for the front left window, the person closest to it is usually the driver. The driver's body shape information can be obtained using pressure sensors in the driver's seat, and the opening range of the front left window can be determined based on this information. Similarly, for the rear right window, the person closest to it is usually the passenger in the right rear seat. The corresponding passenger's body shape information can be obtained using pressure sensors in the right rear seat, and the opening range of the rear right window can be determined based on this information.

[0071] Specifically, if there is only the driver inside the vehicle, then the person closest to the vehicle's four doors and four windows is the driver. Therefore, the opening range of the vehicle's four doors and four windows is determined based on the driver's body size. Obviously, with this setup, each door and each window can be set to its most suitable opening range to allow the nearest person inside the vehicle to be safely removed.

[0072] Furthermore, the collision signal includes a collision location signal, which indicates the location where the vehicle collision occurred; determining the vehicle door opening and / or window opening based on the vehicle's size information may include:

[0073] (1) Determine the location of the vehicle collision based on the collision location signal;

[0074] (2) If the collision occurs on the side of the vehicle, the door opening and / or window opening shall be determined based on the vehicle's body shape information.

[0075] (3) If the collision occurs at a location other than the side, the vehicle door opening and / or window opening shall be set to the preset minimum value.

[0076] The collision signal output by the airbag system can include a collision location signal, which indicates the location of the vehicle collision. This signal can include, for example, a frontal collision signal, a left-side collision signal, a right-side collision signal, and a rear-end collision signal. Based on this collision location signal, the location of the vehicle collision can be determined. For example, if the output collision signal is a left-side collision signal, the collision location can be determined to be the left side of the vehicle. If the collision location is not on the side, such as a frontal or rear-end collision, the vehicle's side is not impacted. In this case, it is generally not necessary to control the opening of the side doors or windows, so the door opening and / or window opening can be set to a preset minimum value (e.g., 0). If the collision location is on the side, it is necessary to control the opening of the side doors or windows. In this case, the corresponding door opening and / or window opening can be determined based on the body shape information of the occupants. Additionally, if the collision occurs on the left side of the vehicle, the left door is generally difficult to open. In this case, you can control the opening of the left window, right door, and right window. If the collision occurs on the right side of the vehicle, the right door is generally difficult to open. In this case, you can control the opening of the right window, left door, and left window.

[0077] Furthermore, the collision signal includes a collision level signal, which indicates the severity of a vehicle collision; determining the vehicle door opening and / or window opening based on body shape information may include:

[0078] (1) Determine the severity of the vehicle collision based on the collision level signal;

[0079] (2) If the severity of the collision is not high-risk, the door opening and / or window opening of the vehicle shall be determined based on the vehicle size information.

[0080] (3) If the severity of the collision is high-risk, the opening of the vehicle doors and / or the opening of the windows are set to the preset maximum value.

[0081] The collision signal output by the airbag system can also include a collision level signal, which indicates the severity of the collision. This signal can be categorized as low-risk, medium-risk, or high-risk. If the collision level signal is low-risk or medium-risk, the collision severity is not high, and the system can determine the door and / or window openings based on the occupants' body shapes. Conversely, if the collision level signal is high-risk, the collision severity is very high, and the system can determine the high-risk level. In a high-risk collision, occupants may suffer serious injury, requiring immediate removal from the vehicle. Therefore, the door and / or window openings are set to the preset maximum values ​​(e.g., 75% or 100%).

[0082] 103. Control the vehicle doors to open according to the door opening degree, and / or control the vehicle windows to open according to the window opening degree.

[0083] After determining the vehicle's door opening and / or window opening based on body shape information, the vehicle controller can control the vehicle's doors to open according to the door opening degree, and / or control the vehicle's windows to open according to the window opening degree. For example, if the body shape information determines that only the door opening degree is 75%, then the door will be controlled to open to 75%; if the body shape information determines that only the window opening degree is 80%, then the window will be controlled to open to 80%; if the body shape information determines that both the door opening degree is 75% and the window opening degree is 80%, then both the door and window will be controlled to open to 75% and 80% respectively.

[0084] When a vehicle collision is detected, in addition to controlling the doors / windows to open to the appropriate size for the occupants, the following safety control mechanisms can also be added.

[0085] In one implementation of this application, the step of detecting a vehicle collision may further include:

[0086] (1) Obtain weather information sent through the cloud server;

[0087] (2) Determine the visibility of the vehicle's surroundings based on weather information;

[0088] (3) If the visibility is less than the set threshold, then activate the vehicle’s rear fog lights.

[0089] The vehicle controller can obtain local weather information from a cloud server. Based on this information, it can determine the visibility of the vehicle's surroundings. If the visibility is less than a set threshold (e.g., 200 meters), it indicates a high risk of secondary accidents due to low visibility. Therefore, the rear fog lights can be activated to warn oncoming vehicles. In actual operation, when a collision occurs, the collision signal (usually output by the airbag system) is transmitted to the body domain controller via the communication bus. The body domain controller then transmits the collision signal to the body controller. Upon receiving the collision signal, the body controller, combined with the weather information from the cloud server, determines the visibility of the vehicle's surroundings. If the visibility is less than a set threshold, it sends a control signal to the vehicle's combination light controller, thereby activating the rear fog lights.

[0090] In another implementation of this application, the step of detecting a vehicle collision may further include:

[0091] Activate the vehicle's hazard warning lights.

[0092] In practice, the collision signal output by the airbag system can be transmitted to the vehicle's body control unit via a communication bus, which then activates the vehicle's hazard warning lights. Activating the hazard warning lights alerts other vehicles and personnel at the scene, further reducing the possibility of secondary accidents.

[0093] In another implementation of this application, the step of detecting a vehicle collision may further include:

[0094] If the collision level signal output by the airbag system is a medium-risk or high-risk signal, then the vehicle's horn will be controlled to sound.

[0095] As described above, the collision signal output by the airbag system can include a collision level signal. If the collision level signal is a medium-risk or high-risk signal, it indicates a high degree of collision severity. In this case, the vehicle's control unit can control the vehicle's horn to sound, specifically limiting the number of horn sounds (e.g., 10 times). Sounding the horn serves two purposes: firstly, it alerts passing vehicles and pedestrians to safety; secondly, it reminds occupants to take emergency self-rescue measures.

[0096] In practical implementation, safety control functions can be added to the vehicle's infotainment system, including the following safety control features: opening doors and windows according to the body shape of occupants in a vehicle collision; activating hazard warning lights; activating rear fog lights; and controlling the horn to sound. Each feature has a switch (e.g., a soft switch in the safety settings of the central control UI), allowing users to enable or disable the corresponding safety control function.

[0097] In this embodiment, when a vehicle collision is detected, the body size information of the occupants is acquired. Then, based on this information, the opening degree of the vehicle doors and / or windows is determined. Finally, the doors are controlled to open at the determined opening degree, and / or the windows are controlled to open at the determined opening degree. This design allows for reasonable control of the opening extent of the doors and / or windows based on the body size of the occupants, thereby facilitating the rescue of those inside the vehicle while reducing the risk of secondary accidents. For example, if the occupants are small, the doors can be opened only slightly, allowing for easy removal from the vehicle. Furthermore, compared to opening the doors significantly, a smaller opening reduces the risk of secondary accidents.

[0098] like Figure 2 The diagram shown illustrates the operation flow of the vehicle collision control method provided in this application embodiment under a practical application scenario. In this application scenario, the vehicle control system mainly includes an airbag system, a body domain controller, a body controller, window controllers, and door controllers, etc. Except for the LIN bus connected to the window controllers, which is a CAN bus, all other communication buses are CAN buses.

[0099] If the vehicle's infotainment system has the collision safety control function enabled (enabled by default at the factory), the airbag system will output a collision signal when a collision occurs, including the collision location signal and the collision level signal. After verification, the collision signal is transmitted to the body domain controller via the CAN bus. The body domain controller then transmits the collision signal to the window controller via the LIN bus and to the door controller via the CAN bus. Seat pressure sensors detect the body size level signal of the occupants and transmit this signal to the window controller via the LIN bus and to the door controller via the CAN bus. Upon receiving the collision location and collision level signals, as well as the body size signal, from the collision signal, the door controller can control the doors to open to the corresponding degrees (e.g., 20%, 35%, 50%, and 75%). Similarly, upon receiving the collision location, collision level, and body size signals from the collision signal, the window controller can control the windows to open to the corresponding degrees (e.g., 35%, 50%, 75%, and 100%). In addition, the collision signal can be transmitted to the body controller via the CAN bus. After receiving the collision signal, the body controller will control the vehicle's hazard warning lights to be turned on. If the collision level signal in the collision signal is a medium risk signal or a high risk signal, the body controller can also control the vehicle's horn to sound. The body controller can also determine whether to turn on the vehicle's rear fog lights by judging visibility based on the weather conditions sent down from the cloud.

[0100] It should be noted that, Figure 2 The topology and communication bus form of the vehicle control system in the application scenario are just examples. In fact, the vehicle collision control method provided in this application embodiment can be applied to vehicle control systems with any topology and any communication bus form. This application embodiment does not limit it in any way.

[0101] In summary, the embodiments of this application provide a safety control mechanism after a vehicle collision, which can facilitate the rescue of people inside the vehicle and effectively reduce the risk of secondary accidents.

[0102] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
