Description

Technical Field

[0001] This invention relates to the field of vehicles, and more particularly to a method for protecting vehicle occupants. Furthermore, the invention also relates to a system for protecting vehicle occupants, a vehicle, and a computer program product. Background Technology

[0002] With the development of intelligent and human-centered vehicles, vehicle driving safety and passenger safety are receiving increasing attention.

[0003] If a vehicle is in a high-voltage environment while in motion or parked, such as when it is in contact with a high-voltage line or when its high-voltage system, such as the power battery, is leaking, the vehicle body may carry a high voltage that could harm the occupants.

[0004] To prevent electric shock to vehicle occupants, vehicle body designs generally employ the so-called "Faraday cage" protection principle. Specifically, the vehicle's frame, chassis, and other metal structures are electrically connected to form a closed, conductive shell—the Faraday cage structure. When the vehicle encounters a high-voltage leak or external electric shock, the high-voltage current is conducted to the ground through the conductive body shell, bypassing the occupants and thus effectively protecting them.

[0005] However, vehicle occupants may not be aware of this high-voltage risk. If a vehicle occupant opens the door to exit the vehicle, a conductive circuit will be formed when the occupant lands on one foot, connecting the high-voltage source to the human body and then to the vehicle's exterior. This poses a serious risk of electric shock to the vehicle occupant.

[0006] Therefore, there is still a need to improve existing technologies to address at least some of the aforementioned problems. Summary of the Invention

[0007] Based on this, the present invention proposes an efficient solution that not only overcomes the shortcomings of existing technical solutions, but also ensures that actions can be taken safely under instruction, thereby avoiding occupant injury and improving user safety.

[0008] According to a first aspect of the present invention, a method for protecting vehicle occupants is provided, wherein the method comprises:

[0009] Step S110: Detect the electric field strength around the vehicle body;

[0010] Step S120: Compare the detected electric field strength with a preset threshold; and

[0011] Step S130: Output instructions to prevent electric shock to vehicle occupants based on the comparison results.

[0012] The basic concept of this invention is to reliably and quickly determine the electrical state of the vehicle body, especially the doors and roof, by utilizing an electric field detection device, such as an electric field sensor, installed on the vehicle. Based on the electrical state of the vehicle body, the invention can correspondingly alert vehicle occupants and control the vehicle accordingly to avoid the risk of electric shock to vehicle occupants. This effectively protects vehicle occupants and improves their safety.

This allows for more flexible and reliable assurance of occupant safety, and further ensures occupant safety.

[0016] In an optional embodiment of the method according to the invention, the method is executed repeatedly at preset time intervals. This optimizes data storage and processing volume, saving computing power for the vehicle controller.

[0017] Alternatively, the method is repeated continuously. This allows for real-time detection of the vehicle's electrical state, improving detection reliability.

[0018] In an optional embodiment of the method according to the present invention, the instructions for preventing electric shock to vehicle occupants include at least one of the following: instructions for outputting visual cues, instructions for outputting auditory cues, instructions for outputting tactile cues, instructions for automatically locking the vehicle doors, instructions for outputting emergency rescue instructions, instructions for automatically disconnecting the vehicle's power supply, and instructions for outputting prompts to the vehicle occupants' mobile terminal devices. This diverse and comprehensive approach ensures flexible and appropriate measures can be implemented under different voltage levels, resulting in more efficient and reliable protection of occupants.

[0019] In an optional embodiment of the method according to the invention, the instructions for emergency escape include at least one of the following: instructions for outputting escape guidance, instructions for automatically opening vehicle doors, and instructions for automatically disconnecting the vehicle's power supply. This allows for more refined and context-specific measures to prevent electric shock to vehicle occupants, avoiding further injury to them.

Therefore, it should not be construed as a limitation of this disclosure. The positional relationships of the constituent elements may be appropriately varied depending on the direction in which each constituent element is described. Therefore, the use of terms not limited to those described in the specification may be appropriately replaced as needed.

[0054] Figure 1 A schematic diagram of a vehicle 1 according to an embodiment of the present invention is shown.

[0055] like Figure 1As shown, vehicle 1 is configured as a passenger car and, exemplarily, an electric vehicle with autonomous driving capabilities. Vehicle 1 includes a power battery that, exemplarily, operates within a voltage range of 550V-930V. Of course, in other embodiments, vehicle 1 may also be configured as other types of vehicles, such as a gasoline-powered vehicle.

[0056] Typically, exterior rearview mirrors 11, such as the left and right exterior rearview mirrors, are located near the A-pillar of vehicle 1. With the help of the exterior rearview mirrors 11, the driver and passengers of vehicle 1 can observe the traffic conditions around vehicle 1, especially behind vehicle 1.

[0057] Figure 2 A schematic diagram of a system 2 for protecting vehicle occupants according to an embodiment of the present invention is shown. According to this embodiment, system 2 includes an electric field detection device 3 and a control device 4. See also Figure 1 An electric field detection device 3 is arranged on the exterior rearview mirror 11. For example, an electric field detection device 3 is arranged on the left and right exterior rearview mirrors respectively. These two electric field detection devices 3 are exemplary constructed as electric field sensors and are arranged on or integrated into the exterior rearview mirror 11, for example.

[0058] Here, the electric field detection device 3 is pointed towards the vehicle 1 and can detect the electric field strength around the vehicle body, especially at the doors and roof. This electric field detection device 3 can detect electrostatic / alternating electric field strengths from 0.1 Hz to 100 kHz and can cover the operating voltage and frequency of the vehicle 1's power battery and high-voltage lines. Therefore, the electric field detection device 3 can detect situations where the vehicle 1 is in contact with high-voltage wires and / or where the vehicle 1's power battery system or high-voltage system leaks current.

[0059] For example, the electric field detection device 3 is electrically insulated from the vehicle body 1 and detects the electric field through a non-metallic area, such as a plastic cover, to avoid metal shielding of the electric field strength detection signal and to avoid damage to the electric field detection device 3.

[0060] The control device 4 is capable of data connection with the electric field detection device 3 and outputs instructions to prevent electric shock to vehicle occupants based on the detection data from the electric field detection device 3. Here, the control device 4 is exemplarily configured as a controller and includes a communication interface for receiving and sending data and / or instructions, a memory for storing data and / or instructions, and a processor (not shown in detail) for processing the received data and / or instructions. In this embodiment, the controller may be a vehicle control unit (VCU) or a domain controller (DC).

[0061] For example, system 2 also includes a prompting device 5 and a door locking / unlocking device 6. The prompting device 5 and the door locking / unlocking device 6 are data connected to the control device 4 and are able to receive instructions sent by the control device 4.

[0062] According to this embodiment, the prompting device 5 can output prompts to prevent electric shock to vehicle occupants based on instructions output by the control device 4. Exemplarily, the prompting device 5 may include at least one of a visual prompting device, an auditory prompting device, and a tactile prompting device. Here, the visual prompting device may be configured as a display screen and, for example, as a central control screen of the vehicle, and the prompts to prevent electric shock to vehicle occupants can be displayed on the central control screen in the form of text, images, or videos. The auditory prompting device may be configured as a speaker and, for example, integrated into the central control screen of the vehicle. Therefore, the prompts to prevent electric shock to vehicle occupants can be output additionally or alternatively in a voice manner. The tactile prompting device may be configured as a vibrator and arranged in the steering wheel and / or seat, thereby enabling additionally or alternatively to prompt vehicle occupants by vibration.

[0063] The door locking / unlocking device 6 can automatically lock / unlock the door based on the command sent by the control device 4.

[0064] like Figure 2 As also shown, system 2 may further include occupant status detection device 8 and / or in-vehicle status detection device 9. Control device 4 is capable of data connection with occupant status detection device 8 and / or in-vehicle status detection device 9 and receiving their data.

[0065] For example, the occupant status detection device 8 can detect the status of vehicle occupants and includes, for example, an in-vehicle camera, an occupant heart rate / blood pressure sensor, etc. The in-vehicle status detection device 9 can detect the safety status inside the vehicle. For example, the in-vehicle status detection device 9 may include an in-vehicle camera, a temperature sensor, a fire sensor, a smoke sensor, etc. In this embodiment, the in-vehicle camera can simultaneously capture images of the occupants and images of the interior of the vehicle, and identify the occupant's status, such as facial expressions of pain, and the safety status inside the vehicle, such as a fire, through image recognition technology.

[0066] Therefore, the control device 4 can also output instructions for emergency escape based on the detection data of the occupant status detection device 8 and / or the vehicle interior status detection device 9.

[0067] According to one embodiment, the control device 4 is also capable of data connection with the vehicle occupant's mobile terminal device 7, such as a smartphone, and can additionally output to the mobile terminal device, especially simultaneously or in parallel with the output to the prompting device 5, instructions for preventing electric shock to the vehicle occupant and / or instructions for emergency escape, thereby enabling prompts to the vehicle occupant from multiple perspectives.

[0068] Below, refer to Figure 3 up to Figure 5 and combined Figure 1 and Figure 2 The method 100 of the present invention will be described in detail.

[0069] Figure 3 A schematic flowchart illustrating a method 100 for protecting vehicle occupants according to an embodiment of the present invention is shown. In this embodiment, method 100 exemplarily includes steps S110 to S130 and is performed by... Figure 2 The system 2 shown is used for implementation.

[0070] In step S110, the electric field strength around the vehicle body, especially at the doors and roof, is detected using the electric field detection device 3. The detected electric field strength can be received by the communication interface of the control device 4 and cached in the memory.

[0071] In step S120, the processor of the control device 4 retrieves the detected electric field strength and compares it with a preset threshold. Here, the preset threshold can be stored in a memory.

[0072] Then, in step S130, the processor of the control device 4 outputs an instruction to prevent electric shock to vehicle occupants based on the comparison result.

[0073] For example, if the detected electric field strength is lower than a preset threshold, it is assumed that there is no voltage that could cause personal injury to the vehicle occupants, and therefore no instruction is output. Thus, method 100 ends and the method steps are repeated. Alternatively, method 100 can be repeated at preset time intervals, such as 5 seconds.

[0074] If the detected electric field strength is not lower than a preset threshold, the vehicle body is considered electrified and the voltage could cause personal injury to the vehicle occupants. Therefore, an instruction is output to prevent electric shock to the vehicle occupants.

[0075] According to this embodiment, the instructions for preventing electric shock to vehicle occupants include at least one of the following: instructions for outputting visual cues, instructions for outputting auditory cues, instructions for outputting tactile cues, instructions for automatically locking the vehicle doors, instructions for outputting emergency rescue instructions, instructions for automatically disconnecting the power supply to vehicle 1, and instructions for outputting prompts to the mobile terminal device 7 of the vehicle occupants.

[0076] According to one embodiment, step S130 further includes sub-steps S131 and S132. In sub-step S131, the detected electric field strength is graded based on the comparison results.

[0077] Here, multiple preset thresholds or threshold ranges can be set. For example, if the electric field strength is below a first threshold, it is considered that there is no voltage that could cause personal injury to vehicle occupants, and therefore the electric field strength is classified as Level 1. If the electric field strength is not lower than the first threshold but is lower than a second threshold, it is considered that the vehicle body is charged and that the voltage could cause personal injury to vehicle occupants. Therefore, the electric field strength is classified as Level 2. If the electric field strength is not lower than the second threshold, it is considered that the vehicle body is charged and that the voltage could cause fatal injury to vehicle occupants. Therefore, the electric field strength is classified as Level 3.

[0078] Then, in step S132, based on the graded output of the electric field strength, an instruction corresponding to the grade is output to prevent electric shock to vehicle occupants.

[0079] For example, if the electric field strength is classified as Level 1, no instruction is output, and method 100 returns from sub-step S132 to step S110. If the electric field strength is classified as Level 2, the control device 4 outputs an instruction to the warning device 5 to prevent electric shock to vehicle occupants. Thus, for example, the visual warning device outputs text and image warnings about the risk of electric shock and displays these warnings to the vehicle occupants, while the auditory warning device outputs voice warnings about the risk of electric shock and the tactile warning device displays vibration warnings. If the electric field strength is classified as Level 3, in addition to outputting an instruction to the warning device 5, an instruction to automatically lock the doors is output to the door locking / unlocking device 6, and then an instruction to automatically disconnect the power supply to the vehicle 1's power supply system is output. Therefore, the door locking / unlocking device 6 automatically locks the door in response to the instruction to prevent vehicle occupants from opening the door and getting out of the vehicle, which could cause fatal danger. Then, the power supply system of vehicle 1 automatically cuts off the power supply to vehicle 1 in response to the instruction, thereby preventing the high-voltage system of vehicle 1 from being damaged or causing an accident after the high-voltage wire comes into contact with vehicle 1, thus avoiding subsequent risks or secondary leakage risks.

[0080] Figure 4 A schematic flowchart of a method 100 for protecting vehicle occupants according to another embodiment of the present invention is shown. The method 100 exemplarily includes steps S110 to S150 and is also... Figure 2 The system 2 shown is used for implementation.

[0081] Figure 4 This embodiment of method 100 is similar to Figure 3 The difference in the embodiments is that the method 100 further includes steps S140 and S150.

[0082] In step S140, the occupant status detection device 8 detects the status of the vehicle occupants, and the vehicle interior status detection device 9 detects the safety status inside the vehicle. Exemplarily, the occupant status detection device 8, as shown above, can detect the health status of the vehicle occupants. Exemplarily, the vehicle interior status detection device 9 may include a temperature sensor and / or a smoke sensor and is capable of detecting a fire inside the vehicle.

[0083] Then, in step S150, an emergency escape instruction is additionally output based on the state of the vehicle occupants and / or the safety status inside the vehicle. For example, if it is detected that a vehicle occupant is experiencing difficulty breathing or a heart attack, or if a fire is detected inside the vehicle and the vehicle occupants must evacuate, then in addition to the instruction for preventing electric shock to the vehicle occupants output in step S132, the control device 4 also outputs an emergency escape instruction.

[0084] For example, the instructions for emergency escape include at least one of the following: instructions for outputting escape guidance, instructions for automatically opening the vehicle door, and instructions for automatically disconnecting the power supply to vehicle 1.

[0085] Therefore, the control device 4 outputs a command to the door locking / unlocking device 6 for automatically opening the door and a command to the prompting device 5 for guiding escape. The door locking / unlocking device 6 automatically opens the door in response to the command, and the prompting device 5 outputs a video to guide escape in response to the command, so that vehicle occupants can avoid electric shock during emergency escape, such as when getting out of the vehicle.

[0086] For example, if the temperature sensor inside the vehicle detects that the interior temperature exceeds a temperature threshold, such as 40 degrees Celsius, or if the smoke sensor detects that the smoke inside the vehicle exceeds a threshold, the control device 4 automatically outputs instructions for emergency escape based on the detection signals from the temperature and smoke sensors. For instance, the control device 4 sends an instruction to the door locking / unlocking device 6 to automatically open the door, and sends an instruction to the prompting device 5, such as the central control screen, to provide escape guidance. The prompting device 5 provides escape guidance to the vehicle occupants visually and audibly based on the corresponding instructions, and the door locking / unlocking device 6 automatically opens the door based on the corresponding instructions, facilitating the safe escape of the vehicle occupants.

[0087] Alternatively or additionally, vehicle occupants can manually trigger the emergency escape function. For example, a vehicle occupant can manually activate the emergency escape function by operating the central control screen of vehicle 1 and pressing and holding the emergency escape button set on the central control screen. The control device 4 outputs instructions for emergency escape based on this manual input signal, such as instructions for opening the vehicle door and instructions for guiding the escape. In addition, to prevent accidental activation of the emergency escape button, it can be configured that vehicle occupants need to press and hold the button three times to manually trigger the emergency escape function.

[0088] It should be noted that in this embodiment, step S140 is performed after step S132. However, in other embodiments, step S140 may also be performed in parallel with step S110.

[0089] Figure 5a and Figure 5b An exemplary application scenario of method 100 according to an embodiment of the present invention is shown. In this scenario, a high-voltage power line is damaged and bridging the vehicle body.

[0090] like Figure 5a As shown, an exemplary central control screen of vehicle 1, serving as a prompting device 5, is illustrated. This central control screen is capable of displaying visual prompts to prevent electric shock to vehicle occupants and escape videos to guide escape. Furthermore, a speaker is integrated into the central control screen, capable of simultaneously outputting voice prompts to prevent electric shock to vehicle occupants and voice prompts to guide escape.

[0091] In accordance with Figure 3 or Figure 4 If method 100 detects that the vehicle body is electrified while the vehicle occupants are in good health and the vehicle interior is safe, the control device 4 outputs a command to the warning device 5 to prevent electric shock to the vehicle occupants. Here, the central control screen displays the warning text: "Vehicle body is electrified, do not get out of the vehicle," and a symbol representing the risk of electrification flashes above the text to remind vehicle occupants not to open the doors and get out. In addition, the central control screen's speaker outputs a corresponding voice prompt. Simultaneously, the door locking / unlocking device 6 automatically locks the doors to prevent vehicle occupants from accidentally opening them. Here, the control device 4 can, exemplarily, control the window lifting device to open the window slightly to avoid the risk of secondary injury to vehicle occupants due to insufficient oxygen inside the vehicle caused by closed windows when they are not allowed to open the doors and get out.

[0092] like Figure 5b As shown, the control device 4 is also connected to the vehicle occupant's mobile terminal device 7, such as a smartphone, and simultaneously outputs instructions to the mobile terminal device 7 to prevent electric shock to the vehicle occupant. In response to this instruction, the mobile terminal device 7 displays, for example, the warning text "Vehicle body is electrified, do not get out of the vehicle" on its screen and flashes a symbol representing the risk of electric shock above the text. Furthermore, the speaker of the mobile terminal device 7 can simultaneously output corresponding voice prompts, and the vibrator of the mobile terminal device 7 can simultaneously output vibration prompts. Therefore, by providing prompts or warnings to the vehicle occupant from multiple aspects, the reliability and effectiveness of the method 100 are further improved.

[0093] The present invention also protects a computer program product comprising computer instructions, wherein the computer instructions, when executed by a controlled device 4, are at least used to assist in implementing the method 100 according to one embodiment of the present invention.

[0094] Other advantages and alternative embodiments of the invention will be apparent to those skilled in the art. Therefore, the invention is not, in its broader sense, limited to the specific details, representative structures, and exemplary embodiments shown and described. Rather, those skilled in the art can make various modifications and substitutions without departing from the basic spirit and scope of the invention.
