Technical Field

[0001] This utility model relates to the field of satellite emergency communication technology, specifically to an in-vehicle safety integrated device and vehicle. Background Technology

[0002] Vehicle emergency rescue is crucial for ensuring traffic safety and protecting the lives and property of passengers. Timely rescue can not only save lives but also reduce losses caused by accidents. Currently, vehicle emergency rescue systems rely on cellular networks to transmit emergency information, aiming to respond quickly to emergencies.

[0003] However, while cellular network-based vehicle emergency rescue systems provide emergency rescue services to some extent, their numerous shortcomings limit their rescue efficiency. First, cellular network signal coverage is limited by the construction of base stations, with signal blind spots frequently occurring in remote and mountainous areas, preventing rescue requests from being sent. Second, network congestion during peak hours can cause delays in emergency signal transmission, which can directly affect the timeliness and effectiveness of rescue efforts. Furthermore, environmental factors such as buildings and inclement weather can interfere with the stability of cellular signals, further reducing the reliability of emergency rescue systems. Summary of the Invention

[0004] In view of this, the present invention aims to provide an integrated vehicle safety device and a vehicle. The various aspects of the present invention will be described in detail below.

[0005] In a first aspect, this utility model provides an in-vehicle safety integrated device, which is installed on a vehicle. The in-vehicle safety integrated device includes: a satellite communication module for the vehicle to communicate with a first device via satellite; a safety execution module for performing safety-related functions when an accident occurs in the vehicle; and a microcontroller unit (MCU) communicatively connected to the satellite communication module and the safety execution module for controlling the safety execution module to perform safety-related functions when an accident is detected in the vehicle. The safety execution module communicates with the first device via the satellite communication module during the execution of safety-related functions.

[0006] As one possible implementation, the safety execution module includes one or more of the following: an airbag system; an emergency call system; and a text message sending and receiving system.

[0007] As one possible implementation, the MCU controls the safety execution module to perform safety-related functions, including one or more of the following: the MCU controls the airbag system to deploy; the MCU controls the emergency call system to make a phone call to the first device via the satellite communication module; the MCU controls the SMS sending and receiving system to send an SMS message to the first device via the satellite communication module.

[0008] As one possible implementation, the vehicle-mounted safety integrated device stores SMS templates, and the MCU controls the SMS sending and receiving system to send SMS messages to the first device through the satellite communication module, including: the MCU reads the SMS templates from the vehicle-mounted safety integrated device and controls the SMS sending and receiving system to send the SMS templates to the first device through the satellite communication module.

[0009] As one possible implementation, the safety execution module includes the airbag system, and the safety execution module also includes one or more of the emergency call system and the SMS sending and receiving system, wherein the airbag system is used to trigger the emergency call system and / or the SMS sending and receiving system to communicate with the first device.

[0010] As one possible implementation, the in-vehicle safety integrated device further includes: a one-button trigger module, which is communicatively connected to the MCU and used to send a trigger command to the MCU; wherein, when the MCU receives the trigger command, the MCU controls the safety execution module to perform safety-related functions.

[0011] As one possible implementation, the MCU is also used to: in response to an accident involving the vehicle, control the interruption of the execution of other functions on the vehicle besides the safety-related functions performed by the safety execution module.

[0012] As one possible implementation, the satellite communication module includes a radio ranging satellite service for bidirectional communication between the vehicle-mounted safety integration device and the first device.

[0013] As one possible implementation, the in-vehicle safety integrated device further includes: a sensor module, which is communicatively connected to the MCU, for collecting the vehicle's safety operation data and sending the safety operation data to the MCU.

[0014] Secondly, this utility model provides a vehicle on which any of the vehicle-mounted safety integrated devices as described in the first aspect are installed.

[0015] Compared to cellular network-based vehicle emergency rescue systems, the vehicle-mounted safety integrated device proposed in this invention has significant advantages. First, the satellite communication-based device can solve the blind spot problem in remote areas. Second, satellite signals are more stable and unaffected by ground conditions. Furthermore, it offers faster response times, enabling rapid transmission of rescue signals and shortening response time. Finally, because the satellite system is independent of ground infrastructure, it remains effective even during natural disasters or network outages. Simultaneously, the device integrates a satellite communication module, a safety execution module, and an MCU, significantly improving rescue efficiency. Moreover, the hardware-integrated vehicle-mounted safety integrated device can directly connect to the vehicle's interfaces, ensuring compatibility across different vehicles and providing higher security and stability.

[0019] Figure 4 The diagram shown is a structural schematic of the vehicle provided by this utility model. Detailed Implementation

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0021] In this invention, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design described as "exemplary" or "for example" in this invention should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0022] When a vehicle encounters an accident or emergency, it typically uses its onboard cellular communication module to make an emergency call. For example, in the event of a traffic accident, the Emergency Call (E-Call) system automatically detects the collision and sends the vehicle's location and accident information to the Emergency Service Center (ESC) via the cellular network.

[0023] However, cellular network-based vehicle emergency rescue systems face numerous challenges in practical applications, impacting their rescue efficiency and overall performance. Firstly, insufficient signal coverage is a significant issue. In many remote and mountainous areas, cellular network signals are often unavailable, creating signal blind spots. Vehicles in these areas may be unable to effectively send distress signals in emergencies, directly affecting the timeliness and effectiveness of rescue efforts.

[0024] Secondly, the stability of cellular network signals is affected by a variety of factors. Tall buildings, various obstacles, and inclement weather can all interfere with signal transmission, leading to communication disruptions. This complex network environment causes signal quality to fluctuate, further increasing the difficulty of vehicle rescue operations.

[0025] Furthermore, network congestion is a significant issue. During peak hours or emergencies, an increase in rescue requests can lead to network congestion, causing delays in information transmission. In emergencies, the speed of rescue response is crucial; delays can result in missed opportunities for rescue and even endanger lives.

[0026] To address the aforementioned issues, this invention proposes an integrated vehicle safety device that combines a satellite communication module, a safety execution module, and an MCU, resolving the problem of low rescue efficiency in cellular network-based vehicle emergency rescue systems. Furthermore, this integrated vehicle safety device ensures compatibility across various vehicles, enhances the device's performance, and further improves rescue efficiency.

[0027] Figure 1 A schematic diagram of an integrated vehicle safety device is shown. It should be understood that... Figure 1 This is merely a schematic illustration of an integrated vehicle safety device and does not constitute a limitation on this utility model. Figure 1 As shown, the vehicle-mounted safety integrated device 100 includes a satellite communication module 110, a safety execution module 120, and an MCU 130. The following description, in conjunction with... Figure 1 A detailed introduction to the relevant modules is provided.

[0028] like Figure 1As shown, the satellite communication module 110 is used to communicate with the first device. This invention does not limit the type of communication satellite; any satellite with communication capabilities is within the scope of this invention. In some embodiments, Tiantong satellite can be used as the communication satellite. The reliable mobile communication service provided by Tiantong satellite can ensure the timely transmission of distress information in areas not covered by cellular networks. For example, when a vehicle is involved in an emergency, the occupants can make a distress call via Tiantong satellite, and the rescue center can quickly answer the call and provide timely assistance.

[0029] In other embodiments, the satellite communication module may also use BeiDou satellites as communication satellites. The BeiDou Navigation Satellite System (BDS) provides reliable positioning and communication services, significantly improving rescue efficiency and response speed. For example, when a vehicle breaks down in a remote mountainous area, the occupants can use BDS's short message communication function to send a distress message to the rescue center, informing them of their location and the nature of the malfunction. Upon receiving the message, the rescue center can quickly arrange for rescue.

[0030] To improve the efficiency and accuracy of emergency response of the vehicle-mounted safety integrated device proposed in this invention, in some embodiments, the satellite communication module can use a satellite with two-way communication capabilities to enhance the vehicle's communication capabilities in various environments, especially in remote areas or accident sites.

[0031] As an example, the satellite communication module can use BDS and leverage its Radio Determination Satellite Service (RDSS) to enable two-way communication between the vehicle-mounted safety integration device (or the vehicle equipped with the vehicle-mounted safety integration device) and the first device. As a more concrete example, when a vehicle is involved in an accident, it can send a distress signal to a rescue center via RDSS, while simultaneously receiving rescue instructions and guidance from the rescue center.

[0032] Compared to the traditional one-way communication mode, the two-way communication mode can provide more opportunities for interaction and response for people in the vehicle, enabling them to proactively seek help and receive professional rescue guidance in emergency situations.

[0033] The first device refers to a device that receives distress messages sent by a vehicle via a satellite communication module. When the communication satellite supports two-way communication, relevant personnel, including but not limited to personnel at the rescue center and emergency contacts, can send rescue instructions to the vehicle and also receive distress messages from the vehicle via the first device. In this invention, the type of the first device is not limited; any device with the communication function of the corresponding communication satellite and capable of effectively receiving and sending emergency distress messages can be used as the first device. Examples include satellite phones, satellite communication computers, and portable satellite terminals, etc.

[0034] Continue to combine Figure 1 , Figure 1 The safety execution module 120 shown is used to perform relevant safety functions in the event of a vehicle accident. For example, the safety execution module 120 may include one or more components that, in the event of a vehicle accident, can each take corresponding safety measures to ensure the safety of the occupants and to facilitate emergency rescue. The following description, in conjunction with... Figure 2 The components included in the safety execution module 120 are described by way of example.

[0035] In some embodiments, as Figure 2 As shown, the safety execution module 120 may include one or more of the following: an emergency call system 1210, an SMS sending and receiving system 1220, and an airbag system 1230. It should be understood that the description of the functional modules included in the safety execution module herein is merely exemplary and not a limitation thereof; the safety execution module may, of course, include other functional modules.

[0036] The emergency call system 1210 establishes a real-time communication connection with the first device via the satellite communication module 110. Based on the emergency call system, the vehicle can have voice calls with the rescue center. As an example, when a vehicle encounters a breakdown, it can use the satellite communication module to inform the rescue center of the vehicle's malfunction and location information via voice call to obtain assistance. As another example, the vehicle can also receive a call from the rescue center through the emergency call system and obtain detailed rescue instructions from the rescue center.

[0037] The SMS sending and receiving system 1220, as a flexible communication system, allows vehicles to send and receive SMS messages with the first device via the satellite communication module 110. For example, a vehicle can send a distress message to the first device through the SMS sending and receiving system, concisely describing the accident situation and location to ensure rapid rescue. Alternatively, the SMS sending and receiving system can also receive reply messages from the rescue center sent through the first device to obtain corresponding self-rescue advice.

[0038] It should be understood that the first device establishing a real-time communication connection with the emergency call system and the first device establishing an SMS communication connection with the SMS sending and receiving system can be the same device or different devices. In other words, in the event of an accident, the vehicle can simultaneously establish both a real-time communication connection and an SMS communication connection with the first device to enhance communication reliability and improve rescue efficiency.

[0039] Continue to combine Figure 2 In addition to the emergency call system 1210 and the SMS sending and receiving system 1220, the safety execution module 120 may also include an airbag system 1230. The airbag system controls the deployment of the airbags. Specifically, in the event of a vehicle collision, the airbag system controls the rapid inflating of the airbags to form a buffer layer, absorbing the impact force and reducing direct contact between occupants and hard objects inside the vehicle (such as the steering wheel, dashboard, etc.), thereby reducing the risk of injury.

[0040] In addition, the airbag system can also be used to control the tension of seat belts. When the airbag inflates and deploys, the airbag system controls the seat belts to tighten rapidly, limiting the movement of occupants to ensure that the airbags deploy in the optimal position, providing maximum protection for the head and chest. It can also disperse the force transmitted to the occupants during a collision, reducing the intensity of the direct impact.

[0041] The airbag system controls the seat belts and airbags to work together to ensure comprehensive protection for vehicle occupants in the event of an accident.

[0042] In serious traffic accidents, occupants may be severely injured or unconscious, making it impossible for them to actively send distress signals through the emergency call system and / or SMS messaging system. In this invention, when the airbag deploys, the emergency call system and / or SMS messaging system are automatically triggered, establishing a communication connection with the first device via a satellite communication module. That is, in some embodiments, the airbag system can be used to trigger the emergency call system and / or SMS messaging system to communicate with the first device. For example, the airbag system can be used to trigger the emergency call system to make a phone call to the first device via the satellite communication module. Another example is that the airbag system can be used to trigger the SMS messaging system to send an SMS to the first device via the satellite communication module. Yet another example is that the airbag system can be used to trigger both the emergency call system to make a phone call to the first device via the satellite module and the SMS messaging system to send an SMS to the first device via the satellite communication module.

[0043] In some embodiments, when a severe collision occurs and the airbags deploy, the emergency call system is quickly activated and automatically sends a communication request to the first device. After the vehicle establishes a communication connection with the first device, rescue center personnel can attempt to communicate with the occupants through the first device. Based on the occupants' responses, they can assess the extent of injury and the severity of the accident, and then take appropriate rescue measures. For example, if the occupants are conscious and able to converse normally, rescue center personnel can inquire about their injuries, the vehicle's condition, and whether they require immediate assistance, and take necessary rescue measures based on the conversation results. Conversely, if the occupants are unconscious and unable to respond, rescue center personnel can quickly dispatch rescue resources for emergency assistance.

[0044] In other embodiments, when the vehicle's airbags deploy, the SMS messaging system automatically sends an SMS message to a first device. The message may include basic information about the accident, the number of occupants, and other key details. Based on this automatically sent message, the rescue center can quickly understand the nature of the accident and decide whether to prioritize dispatching medical teams or rescue forces. For example, when a vehicle collision occurs and the airbags deploy, the vehicle's SMS messaging system automatically sends a message to the first device to inform the driver that an accident has occurred and emergency rescue is needed.

[0045] In other embodiments, to enhance the reliability of communication between the vehicle and the rescue center and improve rescue efficiency, the emergency call module and the SMS sending and receiving module can be triggered simultaneously after the vehicle's airbags deploy. Through the SMS sending and receiving module, the rescue center can promptly learn about the accident situation and location. Simultaneously, through the emergency call system, the rescue center can attempt to communicate with the occupants of the vehicle to further understand the severity of the accident.

[0046] like Figure 1 (or Figure 2 As shown in the diagram, in this invention, the vehicle-mounted safety integrated device 100 (or 200) may further include an MCU 130. The MCU 130 is communicatively connected to the satellite communication module 110 and the safety execution module 120, and is used to control the safety execution module 120 to perform relevant safety functions when a vehicle accident is detected. The following details the communication connection between the MCU and the safety execution module, the communication connection between the MCU and the satellite communication module, and how the MCU controls the safety execution module to perform relevant safety functions after the connection is established.

[0047] The MCU can establish a communication connection with the security execution module to control the security execution module to perform relevant security functions. In this invention, the connection method between the MCU and the security execution module is not limited. In some embodiments, the MCU can connect to the security execution module through an interface. As an example, the MCU and the security execution module can connect through an interface and communicate based on the Debug Universal Asynchronous Receiver / Transmitter (Debug UART) protocol. Specifically, the security execution module typically has a Transmit (TX) pin and a Receive (RX) pin, and the MCU's UART pins (including the RX / TX pins) will be connected to the corresponding TX / RX pins of the security execution module. As another example, the MCU can also communicate with the security execution module through its General Purpose Input / Output (GPIO) pins.

[0048] The MCU can also establish a communication connection with a satellite communication module. This invention does not limit the connection method between the MCU and the satellite communication module. In some embodiments, the MCU can connect to the satellite communication module via a serial communication interface. This serial communication interface method is suitable for short-distance communication and is convenient and easy to set up. For example, the MCU can connect to the RDSS satellite communication module via a UART interface to establish a communication connection.

[0049] In other embodiments, the MCU can also communicate with the satellite communication module wirelessly. For example, the MCU can communicate with the RDSS satellite communication module via its built-in Bluetooth (BT) module.

[0050] After the MCU successfully establishes a connection with the safety execution module and the satellite communication module, the MCU can control the safety execution module (based on satellite) to perform safety-related functions.

[0051] In some embodiments, the MCU can control the emergency call system to communicate with the first device. In this invention, whether the emergency call system is actively triggered by a person inside the vehicle to establish a communication connection with the first device, or when the emergency call system is triggered by the deployment of the airbag to connect with the rescue center, the emergency call system completes the emergency call under the control of the MCU.

[0052] In other embodiments, the MCU can also control the SMS sending and receiving system to communicate with the first device. Similar to the embodiments described above, the SMS sending and receiving system completes SMS communication under the control of the MCU, whether it is actively triggered or automatically triggered.

[0053] In other embodiments, the MCU can also control the airbag system to deploy the airbags. The MCU can acquire and process real-time data from vehicle sensors to determine whether a collision has occurred, thereby controlling whether the airbag system deploys the airbags.

[0054] To provide integrated solutions for vehicle rescue problems, such as Figure 2 As shown, in this utility model, the vehicle safety integrated device 200 may also include a sensor module 210. The sensor module 210 can communicate with the MCU. The sensor module 210 can be used to detect the vehicle's operating status; that is, when a vehicle accident occurs, the sensor module can automatically detect abnormal conditions. The sensor module 210 can be used to collect vehicle safety operation data, meaning that the sensor module can collect relevant data about the vehicle and its occupants without human intervention. This application embodiment does not limit the safety operation data collected by the sensors, as long as this data can be used to determine whether the vehicle and / or its occupants are safe. For example, the safety operation data may include one or more of the following: vehicle speed data, vehicle engine operation data, obstacle information around the vehicle, etc.

[0055] In some embodiments, after collecting the aforementioned safe operation data, the sensor module 210 can send this data to the MCU.

[0056] The sensor module includes one or more sensors. This invention does not limit the type of sensor. The sensor can be an acceleration sensor that collects acceleration data, or a humidity sensor that transmits humidity information, etc.

[0057] As an example, in airbag systems, accelerometers detect changes in acceleration experienced by the vehicle during a collision, triggering airbag deployment. Similarly, in the event of a vehicle accident, humidity sensors monitor the vehicle's humidity levels, crucial for ensuring the safety of occupants and the effectiveness of rescue operations. At a fire scene, high humidity may indicate underlying moisture, potentially impacting the development and execution of rescue strategies.

[0058] In some embodiments, when a vehicle is involved in a severe collision, the sensor module can detect accident-related data such as vehicle speed, impact force, and vital signs of occupants.

[0059] In some embodiments, the sensors can transmit the detected accident-related data to the MCU via, for example, an Advanced and Adaptive Network Technology (ANT) protocol, and send the accident-related data to the rescue center via a satellite communication module. For example, when a vehicle is involved in an accident, including a collision, the sensor module detects the vehicle's condition and the condition of the occupants, transmits this as accident-related data via the ANT protocol, and stores it in the MCU (the storage method will be described in detail later).

[0060] In other embodiments, to provide stable and reliable data transmission, a FAKRA connector can be used during data transmission in ANT devices (ANT protocol-based sensor devices). The FAKRA connector is resistant to harsh environments inside the vehicle, such as vibration, temperature variations, or humidity changes, thus ensuring reliable transmission of accident-related data in the event of an accident. Furthermore, a match circuit can be used to ensure correct transmission and matching of data between the transmitting module (sensor module) and the receiving module (MCU) to rapidly and accurately transmit critical information after an accident.

[0061] After receiving accident-related data from the sensor module, the MCU processes and performs logical judgments on the data, and decides whether to deploy the airbags based on the processing and judgment results. In some embodiments, the MCU can periodically (e.g., every few milliseconds) sample the sensor data. After each sampling, the MCU performs acceleration calculations, collision type determination, and logical judgments on the data to determine whether to deploy the airbags.

[0062] For example, the MCU can calculate the vehicle's acceleration values ​​in various directions based on sampled data and compare these values ​​with a pre-set threshold (such as ±2g) to determine whether a collision has occurred. A collision is considered to have occurred when the acceleration is greater than 2g or less than -2g. Based on the sensor input data, the MCU can determine the direction of the collision, thereby deciding which airbags to deploy. For example, a frontal collision typically triggers the driver and front passenger airbags, while a side collision may trigger the side airbags.

[0063] As mentioned earlier, when the MCU controls the airbag system to deploy the airbags, it will automatically trigger the emergency call system and / or SMS messaging system. At this time, accident-related data obtained from the sensor module will also be sent as additional data to the first device via the communication connection of the emergency call system and / or SMS messaging system. In this way, even if the occupants of the vehicle are unconscious, relevant personnel at the rescue center can be informed of the situation at the accident scene in real time and take corresponding rescue measures.

[0064] To enhance the response speed of the in-vehicle safety integrated device and improve its rescue efficiency during emergency calls, the communication information and / or SMS template corresponding to the first device can be stored in the in-vehicle safety integrated device. This allows the MCU to quickly read the preset SMS template from the storage medium, fill in the necessary accident information (such as the specific location), and immediately send it to the preset first device without needing to constantly input or search for contacts or edit SMS content during an emergency call. In other words, the MCU can read the SMS template and control the SMS sending and receiving system to send the SMS template to the first device via the satellite communication module.

[0065] Regarding the storage method of SMS templates, first device communication information, and the aforementioned accident-related data, this utility model does not limit the scope. In some embodiments, flash memory, which has a large storage capacity, fast read / write speed, and low cost, can be used in the MCU. In other embodiments, the MCU can also use electrically erasable programmable read-only memory (EEPROM) to store some data that is not frequently modified.

[0066] As an example, SMS templates could include Template 1: "I've been in a car accident, at [specific location], please send someone to help immediately!", Template 2: "I need medical assistance, I'm at [specific location]", etc.; the contact list could include "122", "12122", "Contact 1", "Contact 2", etc. It should be understood that the above SMS templates and contacts can be pre-set before the in-vehicle safety integrated device leaves the factory, and can also be edited and modified by the vehicle's occupants after leaving the factory. It should be understood that the SMS template content, format, and contact list listed above are illustrative and do not constitute a limitation on the SMS templates and contact lists.

[0067] like Figure 2 As shown, for the sake of rapid response and convenience, the vehicle safety integrated device 200 proposed in this utility model may also include a one-key trigger module 220. The one-key trigger module 220 is communicatively connected to the MCU 130. When an emergency occurs in the vehicle, the people in the vehicle can send a trigger command to the MCU 130 through the one-key trigger module 220, thereby sending a text message or making a distress call to the first device.

[0068] In this invention, the one-button trigger module and the MCU can be connected via digital signals. Specifically, the output of the one-button trigger module can be connected to the MCU via GPIO pins. When the one-button is triggered, the one-button trigger module outputs a high-level signal (i.e., a trigger command). Upon reading this signal, the MCU can control the emergency call system and / or SMS sending and receiving system to perform response operations. This connection method is very simple and allows the MCU to take various actions based on the input signals. For example, through the one-button trigger module, the vehicle can send an SMS to a first device; or, for example, through the one-button trigger module, the vehicle can send an SMS to a first device.

[0069] In some embodiments, after receiving a trigger command from the one-button trigger module, the MCU, in addition to controlling the safety execution module to perform safety-related functions, can also provide feedback on the execution status of safety functions to the occupants of the vehicle through an interface (such as a GPIO pin). For example, when the driver presses the button to send a text message, the LED on the in-vehicle safety integrated device will flash red; when the text message is successfully sent, the LED will turn green and stop flashing.

[0070] To ensure the proper functioning of the in-vehicle safety integrated device, in the event of a vehicle accident, the MCU can interrupt the execution of all functions on the vehicle except for those performed by the safety execution module, in order to respond quickly to emergencies. In this invention, the interruption source can be various trigger modules. In some embodiments, when an occupant presses the emergency call button, a high-level signal input from the one-button trigger module will trigger the MCU's interrupt mechanism. This may interrupt some non-critical tasks, such as route planning and navigation. Once the emergency call or text message is successfully sent, the interrupted task, such as continuing route planning and navigation, will resume.

[0071] In other embodiments, when a vehicle collision occurs, the airbag system deploys under the control of the MCU. At this time, the MCU's interrupt mechanism is also triggered so that the subsequent emergency call system and / or SMS sending and receiving system functions can be executed normally.

[0072] To facilitate understanding, the following will be combined with... Figure 3 This invention will now describe in detail the vehicle-mounted safety integrated device proposed in this utility model. It should be understood that... Figure 3 This is merely illustrative and does not constitute a limitation on in-vehicle safety integration devices. Figure 3 This is just one possible implementation of the vehicle-mounted safety integrated device proposed in this utility model.

[0073] like Figure 3 As shown, the vehicle-mounted safety integrated device 300 may also include a connector module 310, which serves as a crucial bridge for communication between various electronic modules (or components). Figure 3 As shown, connector module 310 is used to power external devices (such as sensor module 210) and can also send analog or digital signals from sensor module 210 (including such as accelerometer and humidity sensor) to MCU 130. In addition, connector module 210 can also send control signals from MCU 130 to corresponding execution modules (such as airbag system).

[0074] Communication between the MCU and other modules (such as connector modules) is typically based on a Controller Area Network (CAN) transceiver, using the CAN protocol. When the MCU needs to send data, it transmits a digital signal to the CAN transceiver via its TX pin. The CAN transceiver receives the signal from the MCU and converts it into a differential signal format suitable for CAN bus transmission. These two signals are transmitted via CAN-H and CAN-L lines respectively. Differential signal transmission technology effectively enhances anti-interference capabilities, enabling the CAN bus to maintain stable communication in noisy environments.

[0075] Continue to combine Figure 3 The MCU 130 may include a watchdog timer (WTD) 1310, which can prevent the MCU from stalling or looping during operation and ensure the stability and reliability of the vehicle safety integration device by resetting the MCU within a predetermined time.

[0076] In addition, the MCU 130 may also include a crystal oscillator 1320 that provides a clock signal. In automotive safety integration devices, the MCU needs to synchronize with the satellite communication module to send distress signals, and the stable clock signal provided by the crystal oscillator ensures the accuracy and reliability of data transmission.

[0077] like Figure 3 As shown, the MCU 130 can be configured with a Serial Wire Debug (SWD) interface 1330. SWD is a debugging and programming interface that simplifies connections and saves pins. In automotive safety integration devices, the SWD interface can be used for programming, debugging faults, and updating firmware.

[0078] When a satellite communication module, such as RDSS, malfunctions, the MCU can attempt to restore normal operation of the RDSS system by sending a reset signal. For example, when the RDSS communication connection fails or becomes unstable, the MCU can send a reset signal to help the RDSS module establish a stable communication connection.

[0079] In addition, the MCU can control the power supply to the RDSS by sending a Power Enable (PWR_EN) signal. For example, when the vehicle safety integrated device is activated, the MCU can send a PWR_EN signal to the RDSS to power the RDSS module and begin providing communication services. Conversely, when the vehicle safety integrated device is deactivated, the MCU may disable the PWR_EN signal to conserve power and enter a low-power state.

[0080] To further improve the integration level of in-vehicle safety devices, such as Figure 3 As shown, this utility model may further include a power module 330 for providing power to the vehicle-mounted safety integrated device and managing the power of each module. Specifically, the power module 330 includes a battery (BAT) module 3310 and a power management (PWR) module 3320. The BAT module provides electrical energy, while the PWR module monitors and manages the distribution and use of power. The positive (KL30) and negative (KL31) terminals of the BAT module ensure the integrity of the circuit and the stable flow of current.

[0081] The foregoing has described in detail the embodiments of the vehicle-mounted safety integrated device provided by this utility model. The following describes in detail the vehicle embodiments provided by this utility model. It should be understood that the vehicle embodiments describe vehicles equipped with the vehicle-mounted safety integrated device; therefore, the descriptions of the vehicle embodiments correspond to the descriptions of the vehicle-mounted safety integrated device embodiments.
