Description

Technical Field

[0001] This application relates to the technical field of vehicle safety, specifically to a safety warning system, method, and vehicle. Background Technology

[0002] Currently, with the increasing ownership of vehicles year by year, traffic flow is becoming more concentrated under various road conditions. When a vehicle discovers a hazard ahead, it will generally use hazard lights or other means to warn vehicles behind, thereby avoiding rear-end collisions.

[0003] In related technologies, relying too much on manual prompts from the vehicle in front can lead to rear-end collisions if the vehicle in front fails to activate its hazard lights in time or if it is obstructed by the vehicle in front. Summary of the Invention

[0004] This application is made to address the aforementioned problems. According to one aspect of this application, a safety warning system is provided, applied to a vehicle. The system includes: a warning device disposed on the roof of the vehicle; and a control module for acquiring fault information and controlling the warning device to switch between a first state and a second state based on the fault information. When the warning device is in the first state, its height is a first height; when the warning device is in the second state, its height is a second height, and the first height is lower than the second height. The control module is also used to control the warning device to activate for warning purposes.

[0005] For example, the warning device includes a sunroof and a warning light assembly, the warning light assembly being disposed on the sunroof.

[0006] For example, the control module is further configured to: determine the risk level of the fault information, wherein the risk level includes at least a first risk level and a second risk level; and control the working state of the early warning device according to the risk level after the early warning device is activated.

[0007] For example, the control module obtains the risk level of the fault information based on stored mapping data, the mapping data containing the correspondence between the fault information and the risk level; the control module establishes communication with the vehicle's driving assistance system and obtains the fault information through the driving assistance system; wherein, the fault information includes at least: vehicle braking information, forward collision information, airbag deployment information, and engine fault information.

[0008] For example, the control module includes a first controller and a second controller. The first controller is used to: control the sunroof to switch between the first state and the second state, control the early warning device to start, and generate control commands to the second controller according to the risk level. The second controller is used to: control the working state of the early warning device according to the control commands.

[0009] For example, the warning light assembly includes at least two warning lights, and the second controller controls the light intensity and / or the number of warning lights activated according to the control command to control the working state of the warning device.

[0010] For example, the warning device further includes a housing and a locking block. The warning device is disposed at one end of the sunroof near the rear of the vehicle. The housing is connected to the sunroof, the locking block is connected to the housing, and the locking block is provided with a slot for fixing the warning light assembly.

[0011] For example, the control module is further configured to control the sunroof to switch from the second state to the first state under preset conditions, and to control the warning device to close; wherein the preset conditions include at least one of the following: the control module detects that the fault corresponding to the fault information has been resolved, the control module detects that the working time of the warning device has reached a preset time, and the control module detects that the vehicle behind has responded to the warning of the warning device.

[0012] For example, the control module is further configured to establish communication with the image acquisition device of the vehicle to acquire image data of the vehicle behind through the image acquisition device. The control module determines the driving status of the vehicle behind through the image data. When the driving status of the vehicle behind includes deceleration and / or lane change, it is determined that the vehicle behind is responding to the warning of the warning device. When the driving status of the vehicle behind does not include deceleration and / or lane change, it is determined that the vehicle behind is not responding to the warning of the warning device, and the warning device is turned off.

[0013] For example, the control module is also used to establish communication with the vehicle's control switch; the control module receives a start signal from the control switch, controls the sunroof to switch from the first state to the second state based on the start signal, and controls the warning device to start; or, the control module receives a close signal from the control switch, controls the sunroof to switch from the second state to the first state based on the close signal, and controls the warning device to close.

[0014] For example, the system further includes a drive element disposed in the vehicle, the drive element being connected to a portion of the sunroof, and a control module being electrically connected to the drive element, the control module being adapted to control the drive element to operate so that the sunroof switches between a first state and a second state.

[0015] For example, the control module is also used to communicate with the vehicle key to obtain the distance between the key and the vehicle, and to control the warning device to activate to provide a prompt when the distance changes from outside the preset range to within the preset range.

[0016] For example, the height difference between the second height of the warning device when the sunroof is in the second state and the first height of the warning device when the sunroof is in the first state is 30-60mm.

[0017] In another aspect of this application, a safety warning method is provided, applied to a vehicle, the method comprising: acquiring fault information; controlling a warning device to switch between a first state and a second state based on the fault information, and controlling the warning device to activate to provide a warning based on the fault information; wherein, when the warning device is in the first state, the height of the warning device is a first height, and when the warning device is in the second state, the height of the warning device is a second height, and the first height is lower than the second height.

[0018] According to another aspect of this application, a sunroof assembly is provided, comprising: a sunroof; a warning light assembly and a control module; the warning light assembly being disposed at one end of the sunroof near the rear of the vehicle; and the control module being used to control the opening and closing of the sunroof and / or the warning light assembly.

[0019] According to another aspect of this application, a computer storage medium is provided, the computer storage medium storing computer instructions, which, when invoked, are used to execute the above-described security warning method.

[0020] According to another aspect of this application, an electronic device is provided, the device including a processor connected to a memory, the processor being configured to call executable program code stored in the memory to execute the aforementioned security warning method.

[0021] According to another aspect of this application, a vehicle is provided that includes the aforementioned safety warning system or electronic device.

[0022] The safety warning system in this embodiment receives fault information through a control module. After confirming the fault, it controls the warning device to change, raising the height of the warning device. After the warning device is activated, it can provide timely warnings to vehicles behind. Because the height is increased during the warning, vehicles behind can avoid being blocked by vehicles in the middle, promptly detect the warning, and respond, thus avoiding multi-vehicle accidents and improving driving safety.

[0030] To make the objectives, technical solutions, and advantages of this application more apparent, exemplary embodiments according to this application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely a part of the embodiments of this application, and not all of the embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein. Based on the embodiments of this application described herein, all other embodiments obtained by those skilled in the art without inventive effort should fall within the protection scope of this application.

[0031] like Figure 1 As shown in the figure, this application embodiment provides a safety warning system applied to a vehicle, the system including: a warning device and a control module 110.

[0032] The warning device is installed on the roof of the vehicle. The control module 110 receives fault information and controls the warning device to switch between a first state and a second state based on the fault information. When the warning device is in the first state, its height is a first height; when it is in the second state, its height is a second height, with the first height being lower than the second height. The control module 110 also controls the activation of the warning device to issue a warning.

[0033] The safety warning system in this embodiment receives fault information through the control module 110. After confirming the fault, the system controls the warning device to change, raising its height. After the warning device is activated, it can provide timely warnings to vehicles behind. Because the height is increased during the warning, vehicles behind can avoid being blocked by vehicles in the middle, promptly detect the warning, and respond, thus avoiding multi-vehicle accidents and improving driving safety.

[0034] For example, the warning device includes a sunroof 120 and a warning light assembly 130. The warning light assembly 130 is disposed on the sunroof 120. When the warning device enters the second state from the first state, the sunroof 120 tilts up and the position of the warning light assembly 130 rises.

[0035] like Figure 2 The diagram shows a comparison between related technologies and the warning solution of this application. The upper part of the diagram represents the solution in the related technologies. When vehicle A detects a hazard ahead, it alerts vehicle B behind it through various feedback methods (such as hazard lights). After receiving the feedback, vehicle B then alerts vehicle C behind it. In this case, vehicle C cannot obtain the feedback information from vehicle A and relies heavily on vehicle B to judge the hazard ahead. If vehicle B fails to provide timely warning, a rear-end collision may occur due to failure to slow down (change lanes) in time. The lower part of the diagram represents the warning method of this application. When vehicle A detects a hazard ahead, it provides an indication by partially raising and deforming the sunroof in conjunction with the warning device. Even if vehicle B obstructs the view, vehicle C can still receive the warning indication from vehicle A in time, thus enabling a timely response and avoiding multi-vehicle accidents.

[0036] like Figures 3-4The diagram shown is a structural schematic of the warning device in an embodiment of this application. Exemplarily, the sunroof of the vehicle includes a front glass 121 and a rear glass 122, with the front glass 121 movably connected to the vehicle. Exemplarily, the warning device also includes a housing 5 and a locking block 1. The warning device is disposed at one end of the sunroof near the rear of the vehicle, i.e., on the rear glass. The warning light assembly includes at least two warning lights 3. The housing 5 is connected to the front glass 121, and the locking block 1 is connected to the housing 5. The locking block 1 has a slot for fixing the warning lights 3. The housing 5 can be made of resin material, such as PU (polyurethane). The housing 5 and the front glass 121 are fixedly connected by adhesive or other means. When the front glass 121 is tilted up, the sunroof switches from a first state to a second state. When the sunroof is in the first state, the end of the front glass 121 is pressed against the rear glass 122 by the housing 5. Exemplarily, a sealing ring can also be provided on the housing 5 to provide better waterproofing when the sunroof is in the first state. The locking block 1 is located at the bottom of the housing 5, and the locking block 1 can be fixedly connected to the housing 5 by adhesive bonding. Figure 4 The middle block 1 is bonded to the housing 5 with tape 4. The warning light 3 is fixed to the block 1 via a slot, thus tilting up along with the housing 5 and the windshield 121. When the warning light 3 is activated, it warns vehicles behind. Because the windshield 121 causes the warning light 3 to tilt up, raising its height, the warning light 3 reduces obstruction from other vehicles, allowing vehicles further behind to receive the warning information and respond. The warning device is at a second height when the sunroof is in the second state, and at a first height when the sunroof is in the first state. The height difference between the second and first heights is 30-60mm. In some embodiments, the height difference is 30mm.

[0037] For example, the system further includes a drive element connected to a portion of the sunroof, and a control module 110 electrically connected to the drive element. The control module 110 is adapted to control the operation of the drive element to switch the sunroof between a first state and a second state. The drive element may be a linkage mechanism, connected to one end of the front glass 121. The control module 110 sends a first signal to the drive element, which controls the front glass 121 to tilt up, causing the sunroof to switch from the first state to the second state. The control module 110 then sends a second signal to the drive element, which controls the front glass 121 to reset, causing the sunroof to switch from the second state to the first state.

[0038] For example, the warning device also includes a light guide strip 2, which is disposed in a slot and connected to the warning light 3, changing the form of the light emitted by the warning light 3 (e.g., changing from diffused light to a focused beam). The warning light 3 can use multiple LEDs as warning lights, providing warnings by emitting light from the LEDs. The number and intensity of the LEDs can be adjusted, thereby adjusting its operating state by changing the number and intensity of light emitted. The LEDs are evenly arranged, with a spacing of 50mm to 200mm between adjacent LEDs.

[0039] For example, the fault information mentioned above includes, but is not limited to: vehicle braking information, forward collision information, airbag deployment information, and engine fault information. When at least one of these faults is detected, the warning device controls the sunroof to tilt up to switch from a first state to a second state, and simultaneously controls the warning light assembly in the warning device to activate, thereby warning vehicles behind. The control module includes a first controller and a second controller, wherein the first controller is a domain controller installed on the vehicle, and the second controller is a microcontroller, which can be installed on the sunroof or the warning device. The first controller and the second controller communicate with each other. The first controller is mainly used to control the sunroof to switch between the first and second states, and to control the activation of the warning device. The second controller is used to receive control commands from the first controller and control the operating state of the warning device based on the control commands. The operating state of the warning device mainly refers to the number of warning lights activated and the light intensity in the warning light assembly. The more lights activated and the stronger the light intensity, the easier it is for vehicles behind to obtain the warning information, and it can also be used to indicate different levels of risk.

[0040] The domain controller establishes communication with the Advanced Driving Assistant System (ADAS) on the vehicle to acquire various fault information. Based on this information, it determines whether to tilt the sunroof and issues a warning. Upon receiving fault information, the domain controller assesses the risk level and generates different control commands to the secondary controller to adjust the operating state of the warning device. Specifically, the risk levels include at least a first risk level and a second risk level. The domain controller stores mapping data containing the correspondence between fault information and risk levels. For example, for the aforementioned fault information—vehicle braking information, forward collision information, airbag deployment information, and engine fault information—airbag deployment information corresponds to the first risk level, while other fault information corresponds to the second risk level. This is because airbag deployment signifies a collision, and if following vehicles do not respond promptly, a rear-end collision is highly likely; therefore, it is classified as a higher risk level. In some embodiments, other risk levels and correspondences between other fault information and risk levels are also included, which can be configured in the domain controller according to actual usage requirements.

[0041] For example, for LED lights used as warning lights, the second controller will control the LED lights to operate within a brightness range of 1500 cdl-2000 cdl for warning purposes, depending on the risk level. When the domain controller confirms that the risk level corresponds to the first risk level, a control command is sent to the second controller, which then controls all warning lights in the warning device to turn on at the highest brightness to provide a timely warning to vehicles behind.

[0042] The control module is also used to control the warning device to deactivate the warning state under preset conditions. The preset conditions include: the control module detects that the fault corresponding to the fault information has been deactivated, the control module detects that the working time of the warning device has reached a preset time, and the control module detects that the vehicle behind has responded to the warning of the warning device. When the domain controller confirms that at least one of the above conditions has occurred, it will control the sunroof to switch from the second state to the first state, and at the same time control the warning device to stop working and deactivate the warning state.

[0043] For example, the domain controller maintains constant communication with the ADAS to confirm whether the fault corresponding to the fault information in the current state has been resolved, thus determining whether the risk has been eliminated. When the risk is resolved, no further warning is needed. The domain controller also uses built-in timers and other components to determine the operating duration of the warning device, with a preset time of 5 minutes. When the preset duration is reached, the warning state is deactivated to avoid wasting time. Furthermore, the domain controller communicates with the vehicle's image acquisition device to acquire image data of vehicles behind. The image data is used to determine the driving status of the vehicles behind. If the driving status of the vehicles behind includes deceleration or lane changing, it is determined that the vehicles behind have responded to the warning device's warning. If the driving status of the vehicles behind does not include deceleration or lane changing, it is determined that the vehicles behind have not responded to the warning device's warning. Because a hazard has occurred ahead, the vehicles behind can avoid entering the risk area by changing lanes or decelerating, thus indicating that the vehicles behind have responded, marking a successful warning.

[0044] In some embodiments, the sunroof and warning device can be manually activated for warning purposes. Specifically, the control module also establishes communication with the vehicle's control switch. The control module receives an activation signal from the control switch, controls the sunroof to switch from a first state to a second state based on the activation signal, and activates the warning device. Alternatively, the control module receives a deactivation signal from the control switch, controls the sunroof to switch from the second state to the first state based on the deactivation signal, and deactivates the warning device. The control switch can be located near the driver's seat, allowing the driver to observe and determine whether the sunroof needs to be opened and the warning device activated.

[0045] In some embodiments, the warning device, in addition to providing warnings in risky situations, can also be used to alert the user to the vehicle's current location. Specifically, the control module also communicates with the vehicle's key to obtain the distance between the key and the vehicle, and activates the warning device to provide an alert when the distance changes from outside a preset range to within a preset range. When the vehicle is charging at a charging station or parked in a parking lot, the user may find it difficult to immediately confirm the vehicle's location after leaving the vehicle for a period of time. The domain controller in the control module establishes communication with the key and obtains the distance. When the distance changes from outside the range to within the range, it can be confirmed that the user is approaching. At this time, the warning device is activated, and an alert is issued through the warning light component in the warning device, allowing the user to quickly confirm the vehicle's location. In addition, the control module can also control the sunroof to tilt up, making it easier for the user to notice the alert given by the warning light component.

[0046] The safety warning system in this embodiment receives fault information through a control module. After confirming the fault, it controls the sunroof to deform, raising the height of the warning device. After the warning device is activated, the warning light assembly illuminates the vehicle behind, providing timely warning. Because the height is increased during the warning, the vehicle behind can avoid being blocked by the vehicle in the middle, promptly detect the warning, and respond, thus avoiding multi-vehicle accidents and improving driving safety.

[0047] like Figure 5 As shown in the embodiments of this application, a security early warning method is also provided, including the following steps:

[0048] S510, Receive fault information.

[0049] S520: The fault information control and early warning device switches between the first state and the second state, and the fault information control and early warning device is activated to provide early warning.

[0050] When the warning device is in the first state, its height is the first height; when the warning device is in the second state, its height is the second height, and the first height is lower than the second height.

[0051] Figure 6 A flowchart of the security warning method in an embodiment of this application is shown below. Figure 5 The warning method of the security warning system in this application is described in detail.

[0052] S01. First, the ADAS on the vehicle is used to acquire various fault information and send the fault information to the domain controller in the control module. The fault information is shown in the figure, such as detecting the hazard lights of the vehicle in front or detecting a collision with the vehicle in front. It also includes faults detected by ADAS such as engine faults, airbag deployment, and vehicle braking. The domain controller will send the fault information to the domain controller.

[0053] S02. The current vehicle's domain controller (domain controller A in the figure) obtains the above-mentioned fault information and generates instructions based on the fault information. The domain controller also determines the risk level based on the fault information and generates different control instructions to the second controller based on different risk levels.

[0054] S03, The normal start function of the vehicle sunroof is turned off (such as stopping the normal manual full opening function of the sunroof). The drive element controls the sunroof to switch from the first state to the second state based on the above instructions.

[0055] S04. The front glass of the vehicle's sunroof tilts up, causing the warning device to rise in height and the warning light assembly to activate, thereby providing a warning to vehicles behind.

[0056] S05. The second controller receives control commands for different risk levels and is used to control the working status of the warning light assembly.

[0057] S06. The second controller adjusts the working status of the warning device, mainly by controlling the number of warning lights activated and the light intensity. When the risk level is high, more warning lights are activated and the light intensity is high. When the risk level is low, fewer warning lights are activated or the light intensity is low.

[0058] S07: The domain controller and the vehicle's ADAS maintain communication, execute the judgment process, and determine whether preset conditions are met. If the preset conditions are met, the warning device is controlled to close and the sunroof is controlled to return to the first state. The judgment of preset conditions includes: determining whether the warning device has been in operation for a preset duration (the preset duration can be 5 minutes), receiving a signal from the ADAS to confirm whether the risk has been eliminated, and confirming through the vehicle's rear-view camera whether the following vehicles have responded to the warning.

[0059] S08. After confirming that the above preset conditions are met, control the warning and other functions to turn off and control the sunroof to switch from the second state to the first state, while the sunroof resumes its normal functions.

[0060] This application also provides a computer storage medium storing computer instructions, which, when invoked, are used to execute the aforementioned security warning method.

[0061] This application also provides an electronic device, which includes a processor connected to a memory. The processor is used to call executable program code stored in the memory to execute the above-described security warning method.

[0062] This application also provides a sunroof assembly, specifically including: a sunroof, a warning light assembly, and a control module. The warning light assembly is disposed at one end of the sunroof near the rear of the vehicle. The control module is used to control the opening and closing of the sunroof or the warning light assembly. In some embodiments, the control module can control the opening and closing of both the sunroof and the warning light assembly.

[0063] When the sunroof is opened, it deforms and changes from the first state to the second state. The sunroof tilts up and causes the warning light assembly to rise in height. After the warning light assembly is turned on, it provides a warning to the vehicles behind, thereby achieving the effect of warning and prompting, which is beneficial to driving safety.

[0064] This application embodiment also provides a vehicle including the aforementioned safety warning system. The system receives fault information through a control module and, after confirming a fault, controls the sunroof to deform, raising the height of the warning device. After the warning device is activated, the illumination of the warning light assembly can provide timely warnings to vehicles behind. Furthermore, because the height is increased during the warning, vehicles behind can avoid being blocked by vehicles in the middle, promptly detect the warning, and respond, thus preventing multi-vehicle accidents and improving driving safety.
