Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and particularly to a warning light control method, device, electronic device, storage medium and vehicle. Background Art

[0002] In automotive design, the interior styling and aesthetics have always been important considerations. To ensure the integrity and visual appeal of the interior, many vehicles place the mechanical emergency door release or other emergency door opening devices in relatively concealed areas inside the vehicle. For example, these devices may be installed on the bottom surface, front side or rear side of the map pocket and other inconspicuous positions, and usually have no obvious markings. Although this design improves the cleanliness and aesthetics of the interior, it may pose potential safety hazards in case of emergency.

[0003] When a vehicle collides, the whole vehicle loses power or other emergency conditions occur, the people inside the vehicle or the rescue personnel outside the vehicle need to quickly find the mechanical door opening device to open the door. However, since these devices are hidden in inconspicuous positions and lack obvious markings, it may take a lot of time to find them. This delay not only increases the anxiety of the people inside the vehicle, but also may affect the rescue efficiency and even endanger life safety. Especially in the case of severe deformation or power failure of the vehicle, the electronic door opening system may fail, and the mechanical door opening device becomes the only escape route. At this time, it is particularly important to quickly find these devices. Summary of the Invention

[0043] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will elaborate on each embodiment of the present invention with reference to the drawings. However, those of ordinary skill in the art can understand that in each embodiment of the present invention, many technical details are provided to help readers better understand the present invention. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed by the present invention can still be implemented. The following division of each embodiment is for convenience of description and should not constitute any limitation to the specific implementation of the present invention. Each embodiment can be combined and cross-referenced with each other without conflict.

[0044] To ensure the interior styling and aesthetics of the whole vehicle, the emergency latch or other emergency door opening devices for mechanical door opening inside the vehicle are often arranged in a relatively hidden area at the lower part inside the vehicle. However, this setting will pose a great challenge to external rescue or passengers inside the vehicle when, in emergency situations such as vehicle collision and power failure of the whole vehicle, it is necessary to quickly find the emergency latch or other emergency mechanical door opening devices to open the door. At this time, it is difficult for external rescue or passengers inside the vehicle to quickly find the emergency latch or other emergency door opening devices, resulting in delays in escape time and rescue time, bringing great potential safety hazards. Based on the above problems, the present invention proposes a warning light control method.

[0045] Referring to Figure 1 , a flowchart of the steps of a warning light control method provided by the present invention is shown, and the method may include:

[0046] Step 101, when it is detected that a vehicle collision occurs, obtain the collision inertial force generated by the collision.

[0047] When a serious vehicle collision occurs, the vehicle is severely deformed and even the occupants are injured. At this time, it is usually necessary to open the door so that the occupants can escape as soon as possible. However, if the collision is not serious, such as only causing minor scratches on the vehicle, then it is not necessary to open the door to allow the occupants to escape as soon as possible. Based on the above considerations, the present invention is configured to detect the severity of the vehicle collision. During a vehicle collision, the collision inertial force is an important parameter for evaluating the collision severity and vehicle safety performance. The magnitude of the collision inertial force depends not only on the speed change during the collision, but also is closely related to factors such as the mass of the vehicle, the collision time, the collision angle, and the rigidity of the vehicle structure.

[0048] In an actual collision, the vehicle's safety design (such as energy absorption zones, airbags, seat belts, etc.) reduces the harm of inertial force to the occupants by extending the collision time and dispersing the impact force. In addition, the collision angle also affects the distribution of the collision inertial force. A frontal collision usually generates a relatively large collision inertial force, while a side collision may cause greater harm to the occupants due to the lower rigidity of the vehicle structure. By using sensors and in-vehicle systems to monitor the collision data in real time, the collision inertial force can be quickly calculated, and corresponding protection measures can be taken in combination with the vehicle's safety system, such as automatically tightening the seat belt, triggering the airbag, etc., so as to minimize the harm of the collision to the occupants. The present invention is to set an emergency release warning light and power the emergency release warning light based on the collision inertial force to ensure that the warning light provides prompt assistance to the people inside and outside the vehicle.

[0049] It should be noted that in order to ensure that the emergency release handle warning light can still work properly after a vehicle collision, the present invention provides a supercapacitor for it. As an efficient energy storage device, the supercapacitor is often used to provide short-term high-power output for emergency devices (such as warning lights) due to its fast charge and discharge characteristics, that is, it can be used to independently power the emergency release handle warning light. Moreover, when the supercapacitor has low power, the vehicle power supply will charge the supercapacitor. And in order to ensure that the warning light can work properly in an emergency, the system needs to monitor the power state of the supercapacitor in real time and charge it with the battery in time when the power is insufficient. The process is as follows: First, the system obtains the current power of the supercapacitor through a sensor or a charge management module. If it is detected that the current power is lower than a preset power threshold (for example, 80% of the supercapacitor capacity), the system will trigger the control logic and connect the battery and the supercapacitor through the charge management module. This process is usually achieved through a relay or an electronic switch to ensure that the circuit between the two can be safely and reliably established. After the connection is established, the system will further verify the connection status to ensure that the battery can stably charge the supercapacitor. During the charging process, the system needs to monitor the charging current and voltage to avoid overcharging or over-discharging phenomena to extend the service life of the supercapacitor. At the same time, the charging logic can be optimized according to the characteristics of the supercapacitor (such as charging rate, maximum voltage, etc.) to ensure the maximization of charging efficiency. The specific steps include:

[0050] Obtain the current power of the supercapacitor;

[0051] If the current power is less than the power threshold, control the vehicle's battery to establish a connection with the supercapacitor;

[0052] When it is determined that the connection is successful, control the battery to charge the supercapacitor.

[0053] By the above method, it can be ensured that after a vehicle collision, the supercapacitor still independently powers the emergency release handle warning light.

[0054] It should be noted that in order to ensure the safety of the supercapacitor, the present invention arranges it on the underfloor of the seat or other relatively safe areas to avoid damage to the capacitor when the vehicle collides. Moreover, after the accident vehicle is repaired, the battery can replenish the power of the supercapacitor, and the product can be continuously reused without functional failure.

[0055] The present invention also integrates a control module at the supercapacitor and can control power on and off according to the received collision signal. In addition, since the warning light is a prompting device for the emergency handle position, its power supply reliability is directly related to the safety of passengers. Therefore, the power management of the supercapacitor not only needs to be efficient but also requires redundant design. For example, the system can also set multiple power thresholds. When the power is lower than the first threshold, charging is started, and when it is lower than the second threshold, an alarm is triggered to prompt the maintenance personnel to check the system status. In addition, the system can also combine the vehicle's power management strategy to give priority to ensuring the power supply of the supercapacitor when the vehicle is turned off or the battery power is insufficient.

[0056] Step 102, if the collision inertia force is greater than the target preset value, a collision signal is generated.

[0057] The present invention determines whether to generate a collision signal by comparing the collision inertia force with the target preset value, avoiding the mis-illumination of the emergency handle warning light and wasting the power in the supercapacitor.

[0058] In addition, after generating the collision signal, the present invention also sets different flashing frequencies for the emergency handle warning light according to the magnitude of the collision inertia force for hierarchical warning. This design can intuitively convey the severity of the collision to the outside world through the flashing frequency of the warning light, so as to provide more explicit information for rescue personnel or other road users to take corresponding countermeasures. When the collision inertia force is within the first preset range (e.g., mild collision), the system generates a low-frequency flashing signal (such as 1 Hz). This signal usually indicates that the collision has less impact, the vehicle may only be slightly damaged, and the risk of injury to the occupants is relatively low. When the collision inertia force is within the second preset range (e.g., moderate collision), the system generates a medium-frequency flashing signal (such as 3 Hz). This signal indicates that the collision is relatively serious, the vehicle may be damaged to a certain extent, and there may be a risk of injury to the occupants. The medium-frequency flashing signal can attract more attention more prominently, indicating that external assistance or emergency treatment may be required. When the collision inertia force is within the third preset range (e.g., severe collision), the system generates a high-frequency flashing signal (such as 5 Hz). This signal indicates that the collision is very serious, the vehicle may be severely damaged, and the risk of injury to the occupants is relatively high. The high-frequency flashing signal can cause a rapid reaction from the surrounding people with extremely high visual impact, indicating that immediate rescue or medical intervention is required. To achieve this function, the system needs to bind and transmit the collision signal and the flashing signal. The collision signal is used to control the lighting of the warning light, while the flashing signal is used to adjust the flashing frequency of the warning light. The specific steps include:

[0059] If the collision inertia force is within the first preset range, a low-frequency flashing signal is generated;

[0060] If the collision inertia force is within the second preset range, a medium-frequency flashing signal is generated;

[0061] If the collision inertial force is within the third preset range, a high-frequency flashing signal is generated, and the low-frequency flashing signal, medium-frequency flashing signal, and high-frequency flashing signal are transmitted bound to the collision signal.

[0062] For example, if the set target preset value is 1000N, the first preset range is that the collision inertial force is between 1000N and 2000N, the second preset range is that the collision inertial force is between 2000N and 3000N, and the third preset range is that the collision inertial force is greater than 3000N. When the actually detected collision inertial force is 2500N. Since 2500N > 1000N, a collision signal will be generated, and then further judgment is carried out. Since 2000N < 2500N < 3000N, it is determined that the actual collision inertial force is within the second preset range. At this time, a medium-frequency flashing signal is generated, and the medium-frequency flashing signal and the collision signal are transmitted together.

[0063] The above hierarchical warning design not only improves the safety performance of the vehicle but also provides important technical support for the intelligent transportation system.

[0064] It should be noted that in order to ensure the security and reliability of signal transmission, the present invention proposes two signal transmission methods. One is that the airbag controller transmits to the super capacitor via a hard wire, and the other is that the vehicle domain controller transmits to the super capacitor via the CAN network. Specifically, it includes:

[0065] The collision signal is transmitted to the super capacitor of the vehicle via a hard wire by the airbag controller, and at the same time, the collision signal is transmitted to the super capacitor of the vehicle via the controller area network by the vehicle domain controller.

[0066] Among them, the airbag controller is an electronic control unit (ECU) for the vehicle safety system, which is specifically responsible for managing and controlling the deployment of the airbag. It is one of the core components of the vehicle passive safety system, aiming to maximize the protection of the safety of vehicle occupants in the event of a collision. Usually, the airbag controller monitors the dynamic state of the vehicle in real time through multiple sensors installed on the vehicle (such as acceleration sensors, pressure sensors, etc.), obtains real-time data, including acceleration, angular velocity, pressure changes, etc., and then judges whether a collision has occurred based on the sensor data. If the detected acceleration or pressure change exceeds the preset threshold, the airbag controller will determine it as a collision event, and at this time, a collision signal is generated.

[0067] In the present invention, the collision signal generated by the airbag controller not only transmits to the super capacitor to light up the emergency release warning light, but also has other functions. For example, when a collision signal (such as sudden deceleration or impact) is detected, the airbag controller will quickly analyze the severity, type (frontal collision, side collision, rollover, etc.) and direction of the collision. According to the collision analysis results, the airbag controller will decide whether to deploy the airbag, determine which airbags to deploy (such as driver airbag, co-driver airbag, side airbag, curtain airbag, etc.), and control the timing and force of the airbag deployment to ensure that the airbag inflates at the best moment and provides the most effective protection for the occupants. In addition to the airbag, the airbag controller usually also responsible for controlling the seatbelt pretensioner. When a collision occurs, the airbag controller will trigger the seatbelt pretensioner to tighten the seatbelt to reduce the forward displacement of the occupants. It should be noted that the airbag controller is also equipped with an event data recorder (EDR, Event Data Recorder) for recording key data before and after the collision, such as vehicle speed, brake status, seatbelt usage, airbag deployment status, etc.

[0068] The vehicle domain controller (Vehicle Domain Control Unit 0, VIU0) is a highly integrated electronic control unit (ECU) used to manage and coordinate the operation of multiple subsystems in a vehicle. It is one of the core components in the vehicle's electronic and electrical architecture and is usually used in high-end intelligent vehicles or new energy vehicles to achieve centralized control, data interaction, and intelligent management of vehicle functions. When a vehicle collision occurs, the vehicle domain controller can collect environmental data (such as vehicle speed, acceleration, temperature, obstacle distance, etc.) through sensors, cameras, radars, etc. in the vehicle, and use high-performance processors and intelligent algorithms to process and analyze the collected data to generate a collision signal.

[0069] In addition to the above functions, the vehicle domain controller in the present invention has other functions. For example, it can integrate the functions of multiple domains in the vehicle (such as the power domain, chassis domain, body domain, infotainment domain, etc.) to achieve centralized control and coordination. For example, in the autonomous driving mode, VIU0 can coordinate the power system, braking system, steering system, etc. to ensure the safe and stable operation of the vehicle. It can also perform data interaction with other ECUs in the vehicle through high-speed in-vehicle networks (such as CAN, LIN, Ethernet, etc.) to ensure information sharing and collaborative work among subsystems; it can also make real-time decisions based on vehicle status, environmental information, and driver intentions. For example, when detecting an obstacle ahead, VIU0 can coordinate the braking system and the power system to achieve automatic emergency braking.

[0070] Step 103: Control the super capacitor of the vehicle to supply power to the emergency release warning light through the collision signal, so that the emergency release warning light is lit.

[0071] Under normal circumstances, the emergency handle warning light of the present invention is constantly extinguished. When the control module of the supercapacitor receives a collision signal, the circuit between the capacitor and the handle warning light is connected, and the emergency handle warning light will light up, facilitating rescue personnel outside the vehicle or passengers inside the vehicle to quickly locate the emergency handle or other emergency mechanical door opening devices and quickly escape from the accident vehicle. Among them, the emergency handle warning light of the present invention is set to a conspicuous red color, and the brightness is adjusted to the maximum to prevent passengers inside and outside the vehicle from being unable to quickly identify it. The mechanical structure of the emergency handle is the same as that of a conventional emergency handle. The emergency handle warning light of the present invention is deployed on the handle base. It is a low-power warning light, usually less than or equal to 0.2W.

[0072] It should be noted that the lighting duration of the emergency handle warning light is determined by the power of the supercapacitor. The more power, the longer the lighting time. The less power, the shorter the lighting time. Under normal circumstances, after the present invention controls the supercapacitor to supply power to the warning light through the generated collision signal, the emergency handle warning light will remain constantly on until the supercapacitor can no longer supply power to the emergency handle warning light. At this time, the control module cuts off the circuit between the capacitor and the warning light, and the light goes out.

[0073] However, other settings can also be made. For example, in order to prevent the supercapacitor from over-discharging, thereby protecting its service life and performance, and also to ensure the normal operation of the emergency handle warning light even when the rescue time is too long, the present invention will monitor the lighting duration of the warning light in real time after the supercapacitor supplies power to the warning light. If it is detected that the lighting duration exceeds a preset time threshold (for example, 10 minutes), the connection between the supercapacitor and the warning light will be actively cut off. However, in some special cases, such as after a vehicle collision accident, the vehicle cannot be started normally, but the sensors (such as infrared sensors, cameras or radars) are not malfunctioning. At this time, when there are people (possibly rescue personnel or other passers-by) within a preset range outside the vehicle (such as within 5 meters), the system needs to detect the presence of people through the sensors and reactivate the supercapacitor to supply power to the warning light. This design can ensure that the warning light can be lit again when external assistance is needed, providing clear guidance for rescue personnel, thereby improving the rescue efficiency and success rate. The specific steps include:

[0074] Obtain the lighting duration of the emergency handle warning light;

[0075] When it is detected that the lighting duration is greater than the time threshold, cut off the connection between the supercapacitor and the emergency handle warning light;

[0076] When it is sensed that there are people within the preset range outside the vehicle, control the supercapacitor of the vehicle to supply power to the emergency handle warning light again.

[0077] By optimizing the charge and discharge management of the supercapacitor, the above steps can maximize its service life and reduce the vehicle's maintenance costs while ensuring safety.

[0078] It should be noted that when the collision accident of the vehicle is relatively serious, the vehicle cannot start normally and it is detected that the sensors (such as infrared sensors, cameras or radars) cannot work normally. At this time, when it is detected that the lighting duration is greater than the time threshold, after disconnecting the connection between the supercapacitor and the emergency release warning light, after waiting for a certain duration (such as 3 minutes, 4 minutes, etc.), control the vehicle's supercapacitor to supply power to the emergency release warning light again.

[0079] In addition, in order to implement the above functions, the present invention also integrates a variety of sensors and intelligent control logics. For example, detect the activities of people outside the vehicle through infrared sensors or cameras, monitor the power status of the supercapacitor through the power management module, and realize the connection and disconnection of the circuit through the control module. In addition, the vehicle networking (V2X) technology can be combined to transmit the vehicle's status information (such as collision severity, warning light status, etc.) to the nearby rescue center or other vehicles in real time, so as to achieve more efficient cooperative rescue.

[0080] Because a vehicle usually has multiple doors, when passengers sitting in different positions are rescued, they usually choose the nearest door. And each door has an emergency release, so the number of emergency release warning lights set in the vehicle is the same as the number of emergency releases. That is, if the vehicle has 4 doors and 4 emergency releases are set at this time, then 4 emergency release warning lights are also set.

[0081] Furthermore, in order to ensure that the emergency release warning light can work normally under any circumstances, the present invention can also set up a backup emergency release warning light, that is, multiple emergency release warning lights are set at each emergency release, and then their working states are monitored in real time, and the backup emergency release warning light is started when an abnormality is detected to ensure the continuity of the safety function. Among them, the present invention obtains the working state of the emergency release warning light through a sensor or a circuit detection module. The detected contents include the lighting state of the emergency release warning light, whether the current and voltage are normal, and whether there are faults such as short circuits or open circuits. If it is detected that the emergency release warning light cannot be lit, the brightness is insufficient or the circuit is abnormal, its working state will be immediately judged as abnormal. After detecting an abnormality, the backup emergency release warning light will be started. The backup emergency release warning light usually adopts an independent power supply line and control module from the main emergency release warning light to ensure seamless switching when the main emergency release warning light fails. The start of the backup emergency release warning light can be realized through a relay or an electronic switch, and the system will detect the working state of the backup light again after switching to ensure its normal operation. The specific steps include:

[0082] Obtain the working state of the emergency release warning light;

[0083] If the working state of the emergency release handle warning light is abnormal, the backup emergency release handle warning light is activated.

[0084] In addition, the present invention also sets a fault alarm function, that is, when it is detected that the main warning light is abnormal and switched to the backup light, the present invention sends a fault alarm message to the driver or the rescue center through the vehicle-mounted display screen or wireless communication, prompting that maintenance or repair is required. A multi-level detection mechanism is also set, that is, the main warning light and the backup warning light are regularly self-checked to ensure that both are in a usable state. If the backup light is also abnormal, a higher-priority alarm (such as a sound alarm or a remote notification) will be triggered.

[0085] In summary, the system architecture diagram corresponding to the warning light control method in the present invention is as Figure 2 shown, and includes an airbag controller, a vehicle domain controller, a super capacitor, and an emergency release handle warning light. Among them, the super capacitor includes a charging management module, a control module, and a capacitor. The airbag controller is connected to the super capacitor through a hard wire, and the vehicle domain controller is connected to the super capacitor through a controller area network. The vehicle's battery is controlled by the charging management module to charge the super capacitor, and the capacitor independently supplies power to the emergency release handle warning light, while the control module controls the on-off power between the capacitor and the emergency release handle warning light.

[0086] In addition to generating a collision signal by detecting the collision inertial force and controlling the vehicle's super capacitor to supply power to the emergency release handle warning light according to the collision signal to turn on the emergency release handle warning light. The present invention can also consider generating a collision signal in other ways. For example, voice control, that is, when the vehicle is collided and the vehicle occupants try to self-rescue, by saying commands such as "turn on the emergency release handle warning light", "activate the emergency release handle warning light", etc., the vehicle's super capacitor is controlled to supply power to the emergency release handle warning light to turn on the emergency release handle warning light. It is also possible to control the vehicle's super capacitor to supply power to the emergency release handle warning light by detecting the degree of deformation of the car door and the vehicle body.

[0087] The warning light control method provided by the present invention, when it is detected that the vehicle has a collision, obtains the collision inertial force generated by the collision. If the collision inertial force is greater than the target preset value, a collision signal is generated to avoid false triggering. Through the collision signal, the vehicle's super capacitor is controlled to supply power to the emergency release handle warning light to turn on the emergency release handle warning light, so that the vehicle occupants and rescue personnel can quickly find the position of the emergency release handle and shorten the rescue time. And by using the super capacitor for power supply, it can still supply power to the warning light when there is a problem with the vehicle power supply, enhancing the performance stability. Therefore, the present invention significantly improves the rescue efficiency and safety after a collision by setting the emergency release handle warning light, and the vehicle has the advantages of energy conservation, environmental protection and rescue stability by setting the super capacitor, providing better protection for passengers and rescue personnel.

[0105] The warning light control method provided by the present invention, in the case of detecting a vehicle collision, acquires the collision inertial force generated by the collision. If the collision inertial force is greater than a target preset value, a collision signal is generated to avoid false triggering.

And by using the super capacitor for power supply, power can still be supplied to the warning light when there is a problem with the vehicle power supply, enhancing the performance stability. Therefore, the present invention significantly improves the rescue efficiency and safety after a collision by setting the emergency release warning light, and enables the vehicle to have the advantages of energy conservation, environmental protection and rescue stability by setting the super capacitor, providing better protection for passengers and rescue personnel.
