[0002] In the automotive industry, as the number of electronic control units (ECUs) increases and the complexity of distributed electronic systems increases, LIN (Local Interconnect Network) bus is widely used as a low-cost serial communication protocol to connect and manage these ECUs. The main advantages of LIN bus are its simplicity, cost-effectiveness, and effective support for vehicle network communication. However, with the development of technology and the increase in testing needs, traditional LIN bus testing and calibration methods have gradually exposed some limitations and shortcomings.

[0003] Technicians usually need to destroy the original bus harness or use a simple connected harness as a three-way or four-way. These temporary test solutions are prone to damage the vehicle harness due to irregular harnesses or direct wire breakage, or incomplete functions that make it impossible to perform other functional tests. In addition, when updating the product program, in order to avoid bus conflicts, it is necessary to disconnect the vehicle LIN bus and only keep the device connection. This is usually done by directly cutting the harness, which is inconvenient to operate and brings trouble to the work of calibration test engineers. These methods not only increase the workload and reduce work efficiency, but also increase the possibility of errors, and also pose a threat to the safety and reliability of the vehicle.

[0038] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0039] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0040] In the modern automotive industry, with the increase of electronic control units (ECUs) and the complexity of distributed electronic systems in vehicles, LIN (Local Interconnect Network) bus, as a cost-effective serial communication protocol, plays an increasingly important role in the connection and management of ECUs. LIN bus is popular for its simplicity, cost-effectiveness and strong support for vehicle network communication. However, with the advancement of technology and the increase in testing requirements, traditional LIN bus testing and calibration methods have begun to show limitations.

[0041] Specifically, when technicians conduct data monitoring or product benchmarking tests on LIN bus products, they often have to use destructive methods, such as directly destroying the bus wiring harness, or Figure 1As shown, non-standard simple connection harnesses are used as three-way or four-way connections. These temporary solutions not only easily lead to damage to the vehicle harness, but also fail to fully perform all functional tests due to the lack of standardization. In addition, when the ECU needs to be updated to avoid bus conflicts, the common practice is to cut the harness directly, which is not only cumbersome to operate, but also brings many inconveniences to the work of calibration test engineers. These traditional methods not only increase the workload and risk of error, but also may threaten the safety and reliability of the vehicle.

[0042] In view of the above problems, the present invention proposes a calibration monitoring development board and a method for using the same.

[0043] like Figure 2 As shown, the embodiment of the present application provides a calibration monitoring development board, including: at least two bus interfaces 10, bus switches 20 with the same number as the bus interfaces, and an electrical data measurement interface 30. Among them,

[0044] The at least two bus interfaces 10, each bus interface 10 is configured with corresponding electrical connection terminals for electrically connecting to the vehicle LIN bus and a LIN node corresponding to at least one target automobile component, so as to perform calibration and monitoring operations on the target automobile component.

[0045] Specifically, the development board is equipped with at least two bus interfaces 10, and the design of these bus interfaces 10 takes into account multiple factors, including compatibility, reliability and ease of use. Each bus interface 10 is capable of supporting a communication protocol consistent with the LIN bus specification, ensuring seamless integration with the existing vehicle network. In addition, by configuring a dedicated electrical connection terminal for each bus interface 10, the development board is able to provide a stable and reliable connection. Each bus interface 10 is able to independently communicate with the vehicle's LIN bus or a specific target automotive component. This independence provides the development board with flexibility, enabling it to monitor multiple automotive components simultaneously, or focus on the calibration and monitoring of a single component when necessary.

[0046] During operation, the development board can send control commands to target automotive components and receive component status information and feedback data through these bus interfaces 10. These data are essential for evaluating component performance, diagnosing potential faults, and making necessary calibration adjustments.

[0047] In some embodiments, among the at least two bus interfaces 10, one bus interface 10 is used to be electrically connected to the vehicle LIN bus, and is used to receive and send information from the vehicle LIN bus; the remaining bus interfaces 10 are electrically connected to different LIN nodes respectively; wherein each bus interface 10 is connected to the corresponding LIN node through an independent electrical path, and is used to independently receive data of the target vehicle component connected to the corresponding LIN node.

[0048] Specifically, the main function of the vehicle LIN bus interface 10 is to receive and send information from the vehicle LIN bus to ensure that the development board can communicate with the vehicle's central control unit or other LIN network nodes. The vehicle LIN bus interface 10 is connected to the vehicle's LIN bus through an independent electrical path to ensure the stability and reliability of communication. The target vehicle component LIN node interface is used to electrically connect to the LIN nodes of different target vehicle components. These interfaces allow the development board to independently receive data from the target vehicle components connected to the corresponding LIN nodes, thereby realizing the calibration and monitoring of multiple vehicle components.

[0049] The number of vehicle LIN bus interfaces 10 and target vehicle component LIN node interfaces can be expanded as needed to accommodate different vehicle models and different numbers of LIN nodes. For example, if more vehicle components need to be monitored and calibrated, the development board can be designed to include more bus interfaces 10.

[0050] In some embodiments, the target automobile parts include one or more of the following combinations: automobile wipers, window control systems, seat adjustment systems, air conditioning control systems, or lighting systems; wherein,

[0051] The calibration monitoring development board is used for communication between the whole vehicle LIN bus and the target LIN node corresponding to the target automobile component, so as to realize calibration and monitoring of the target automobile component.

[0052] Specifically, the target vehicle components refer to specific functional modules in the vehicle that are connected to the vehicle LIN bus. These modules can communicate, calibrate and monitor through the calibration monitoring development board.

[0053] Car wipers: This system is responsible for controlling the wiper action of the vehicle's front windshield to ensure good visibility in rainy or dirty conditions. The calibration monitoring development board can monitor the working status of the wiper, including speed, response time, etc., and perform necessary calibration to optimize its performance by communicating with the LIN node corresponding to the wiper.

[0054] Window control system: This system controls the raising and lowering of windows so that passengers can control the ventilation and vision in the car. The development board can monitor the position status of the windows by connecting to the LIN node of the window control module and calibrate to ensure smooth operation and correct response of the windows.

[0055] Seat adjustment system: This system allows the driver and passengers to adjust the seat position for optimal driving or riding comfort. The calibration monitoring development board can monitor the position and adjustment status of the seat by communicating with the LIN node of the seat adjustment system, and calibrate to ensure the accuracy and responsiveness of the seat adjustment.

[0056] Air conditioning control system: This system is responsible for regulating the temperature and air circulation in the car to ensure the comfort of passengers. The development board can monitor the working status of the air conditioner, including temperature setting, fan speed, etc., and calibrate to optimize air conditioning performance and energy consumption by connecting to the LIN node of the air conditioning control module.

[0057] Lighting system: This system includes lighting equipment inside and outside the vehicle, such as headlights, taillights, interior lights, etc. The calibration monitoring development board can monitor the status of lighting equipment by communicating with the LIN node of the lighting system, and calibrate to ensure that the brightness and response time of the lighting meet safety standards.

[0058] Furthermore, in some embodiments, the data of the target automobile component includes one or more combinations of the following: sensor readings, including one or more combinations of speed, position, temperature and pressure; execution status of control commands, including the response and execution results of the whole vehicle to the control instructions issued by the target automobile component; fault diagnosis data, including fault codes, error logs and diagnostic requests; performance parameters, including operating performance and efficiency indicators of the target automobile component; configuration and calibration data, used to set the operating parameters and calibration information of the target automobile component; synchronization and timing information, used to ensure the synchronization of data transmission between the whole vehicle LIN bus and the LIN node related to the target automobile component.

[0059] Specifically, the calibration monitoring development board is able to receive and process multiple data types from target automotive components. This data is essential for monitoring the performance of automotive components, diagnosing problems, performing calibration, and ensuring system synchronization.

[0060] Sensor Readings: The board is capable of receiving sensor data from target automotive components including, but not limited to, readings of wiper request speed, ambient light intensity, infrared intensity, temperature, and humidity.

[0061] Execution status of control commands: The development board can monitor the vehicle's response and execution results to control commands issued by the target vehicle component. This includes confirming whether the control commands have been received, processed, and whether the target vehicle component has executed these commands as expected. For example, if a command to close a window is sent, the development board can verify that the window has moved to the closed position.

[0062] Fault diagnostic data: The development board is able to receive and analyze fault diagnostic data, including fault codes, error logs, and diagnostic requests. This data is critical to identifying and resolving potential problems with the target vehicle components. For example, if the air conditioning system fails to reach the set temperature, the development board can provide a fault code to help technicians quickly locate the problem.

[0063] Performance parameters: The development board can monitor the operating performance and efficiency indicators of the target automotive components, such as power consumption, response time, durability and reliability. These parameters help to evaluate the performance of the components and optimize them if necessary.

[0064] Configuration and calibration data: The development board can receive and send configuration and calibration data, which is used to set the operating parameters and calibration information of the target automotive component. This includes adjusting sensor sensitivity, setting predetermined values, or calibrating the device to ensure precise operation.

[0065] Synchronization and timing information: To ensure the synchronization of data transmission between the entire vehicle LIN bus and the LIN nodes related to the target automotive components, the development board can handle synchronization and timing information. This includes ensuring that data packets are sent and received at the correct time and maintaining consistency in data transmission in the network.

[0066] The bus switches 20 are the same in number as the bus interfaces 10 , and each bus switch 20 is electrically connected to a corresponding bus interface 10 , and is used to control the on / off of a signal of the corresponding bus interface 10 , so as to isolate or activate the connection with the target automobile component.

[0067] Specifically, each of the bus switches 20 is designed to be electrically connected to a corresponding bus interface 10. This one-to-one design allows for individual control of each bus interface 10, thereby achieving precise management of signal on and off. By operating these switches, the user can isolate or activate the connection with the target automotive component. For example, when a specific target automotive component needs to be tested or calibrated individually, the corresponding bus switch 20 can be disconnected to isolate the LIN node of the component to ensure the accuracy of the test; when communication needs to be established with the target automotive component, the corresponding bus switch 20 can be closed to activate the connection with the component, allowing the development board to send and receive data and perform monitoring and calibration operations.

[0068] Furthermore, the design of the bus switch 20 takes into account the ease of operation, so that the user can easily control the switch state through physical operation or through integrated control software. The design of the bus switch 20 allows the development board to be compatible with different numbers of LIN nodes and can be easily expanded as needed. If more LIN node connections need to be added, only the corresponding bus interface 10 and the bus switch 20 need to be added.

[0069] The electrical data measurement interface 30 is electrically connected to the bus interface 10 through the bus switch 20, and is used to measure electrical parameters on a target LIN node connected to the target automobile component to monitor the operating status of the target automobile component.

[0070] In some embodiments, the electrical data measurement interface 30 includes at least one current measurement interface 31 and at least one voltage measurement interface 32, which are used to detect the stability of current and voltage of the target automotive component connected to the target LIN node during calibration and monitoring; wherein the current measurement interface 31 is used to measure the current of the target LIN node in real time to detect the current state of the target LIN node; and the voltage measurement interface 32 is used to measure the voltage of the target LIN node in real time to detect the voltage state of the target LIN node.

[0071] Specifically, the design of the current measurement interface 31 and the voltage measurement interface 32 not only ensures the high accuracy of the measurement results, but also can capture tiny current and voltage changes. By monitoring the changes in current and voltage in real time, the abnormal conditions of the target automotive components can be quickly identified and responded to. In addition, the measured data can be processed and analyzed, the operating mode can be identified, potential faults can be predicted, and optimization suggestions can be provided. In some embodiments, in order to enable the user to intuitively understand the measurement results of current and voltage, the development board can be equipped with a user interface, such as an LCD display or an LED indicator light. These interfaces enable users to take necessary actions quickly. At the same time, in order to ensure the safety of the measurement process, the current measurement interface 31 and the voltage measurement interface 32 can include overload protection and short-circuit protection functions to prevent damage to the development board or target automotive components during the measurement process.

[0072] In some embodiments, Figure 2 , further comprising the tool interface 40, wherein the tool interface 40 is electrically connected to the bus interface 10 via the bus switch 20, and is used for burning firmware or application programs into the control unit of the target automobile component connected to the target LIN node.

[0073] Specifically, the integration of the tool interface 40 enables the development board to be used as a multifunctional interface device, which is not limited to data reading and monitoring, but also capable of deeper system-level operations. Through this interface, technicians can easily update or modify the software in the control unit of the target automotive component without disassembling or directly accessing the control unit. This remote update capability greatly improves the efficiency of maintenance and upgrades, while also reducing the complexity and cost of operations.

[0074] In addition, the design of the tool interface 40 also takes compatibility and security into consideration. It supports multiple communication protocols and data formats to ensure compatibility with control units of target automotive components of different manufacturers and models. At the same time, the interface also includes necessary security mechanisms, such as data encryption and verification, to prevent unauthorized access and potential network attacks.

[0075] In actual applications, the use process of the tool interface 40 generally includes the following steps: first, establish a connection with the target LIN node through the bus switch 20; then, send a firmware or application update instruction through the tool interface 40; then, monitor the burning process to ensure that the data is correctly transmitted and stored in the control unit of the target automotive component; finally, verify whether the update is successful, and perform necessary tests to ensure that the performance and function of the target automotive component meet expectations.

[0076] In some embodiments, the fixed suction cup 50 is also included. The fixed suction cup 50 is set on the edge or back of the development board and is used to firmly fix the calibration monitoring development board on the glass, rearview mirror or body of the vehicle.

[0077] Specifically, the design of the fixed suction cup 50 carefully considers the material and shape of different vehicle surfaces. It is usually made of soft and durable materials, such as rubber or silicone, to ensure that the suction cup can be firmly attached to the smooth surface while reducing damage to the vehicle surface. The size and shape of the suction cup may also be optimized according to the weight and shape of the development board to provide sufficient support and stability.

[0078] During the installation process, the user only needs to align the fixed suction cup 50 with the edge or the predetermined position on the back of the development board, and then gently press it to form a seal between the suction cup and the vehicle surface, thereby generating sufficient adsorption force. Figure 3 As shown in the figure, the calibration monitoring development board is fixed on the car rearview mirror through a fixed suction cup. This quick and easy installation method allows the calibration monitoring development board to be quickly deployed at any position in the vehicle, greatly improving work efficiency.

[0079] In addition, the design of the fixing suction cup 50 also takes reusability into consideration. After completing the calibration and monitoring tasks, the user can easily remove the development board from the vehicle surface without leaving any traces or causing damage. This design makes the fixing suction cup 50 both practical and environmentally friendly because it reduces the reliance on disposable fixing equipment.

[0080] Furthermore, the fixed suction cup 50 may also be equipped with a locking mechanism, such as a button or a lever, to ensure that the suction cup will not be accidentally released during vehicle driving. This additional safety feature provides additional peace of mind for the user, especially at high speeds or in adverse weather conditions.

[0081] In some embodiments, the power indicator light 60 is also included. The power indicator light 60 is electrically connected to the power input terminal of the calibration monitoring development board to indicate whether the development board receives power and whether the power status is normal.

[0082] Specifically, the power indicator light 60 is electrically connected to the power input terminal of the development board and is usually located in a conspicuous position on the development board for easy observation by the user. When the development board is properly connected to the power supply, the power indicator light 60 will light up, providing visual feedback that the power is on and the development board is ready for operation. If the power indicator light 60 does not light up or displays an abnormality, the user can quickly identify possible power problems, such as a poor connection, a power failure, or a problem with the development board itself.

[0083] The design of the power indicator light 60 takes into account different power status displays, which may include but are not limited to the following modes: always on means the power is normal, blinking means the power is unstable or the development board is performing some operations, and off means there is no power connection. These different display modes can help users understand the power and working status of the development board more accurately.

[0084] Furthermore, the power indicator light 60 can use different colors to further distinguish different states, such as green for normal operation, yellow for warning or abnormality, and red for serious error or failure. This color coding system provides users with a quick and intuitive way to identify the status of the development board.

[0085] The design of the power indicator 60 also takes energy efficiency and durability into consideration. It generally uses low-power LED lights to reduce the impact on the overall power demand while ensuring long life and reliability. In addition, the circuit design of the power indicator 60 can protect the LED from damage under different voltage and current conditions, ensuring its long-term stable operation.

[0086] In some implementations, a communication protocol conversion interface is further included, and the communication protocol conversion interface is used to achieve compatibility with target automobile components with different communication protocols.

[0087] Specifically, the core function of the communication protocol conversion interface is that it can convert the communication protocol of the development board into the protocol used by the target automotive component, and convert the protocol of the target automotive component into a protocol that the development board can recognize. This two-way conversion capability enables the development board to read, interpret and send data that conforms to the target component protocol, greatly expanding the application scope of the development board.

[0088] The design of this interface takes into account a variety of popular automotive communication protocols, including but not limited to LIN, CAN, FlexRay, etc. By integrating the corresponding hardware and software algorithms, the communication protocol conversion interface can intelligently identify the protocol type of the target component and automatically perform the necessary conversion. This intelligent design reduces the complexity of the user's operation process, allowing users to calibrate and monitor the target component without having to deeply understand the details of various communication protocols.

[0089] Furthermore, the communication protocol conversion interface may include a series of preset protocol libraries, which contain parameters and rules of various automotive communication protocols. When the development board is connected to a new target component, the interface will automatically match and load the corresponding protocol library to achieve seamless communication.

[0090] In addition, to improve the security and reliability of communications, the communication protocol conversion interface may also include encryption and decryption functions to ensure that the data converted between different protocols remains secure and intact. This is especially important when processing sensitive information such as fault diagnosis data and configuration parameters.

[0091] In practical applications, the use process of the communication protocol conversion interface usually includes the following steps: first, identify the communication protocol of the target automotive component; then, perform protocol conversion through the communication protocol conversion interface; then, establish a communication connection with the target component; finally, send and receive data.

[0092] In one implementation of the present application, Figure 4 As shown, the embodiment of the present application provides a method for using a calibration monitoring development board, which is characterized by steps S110 to S150, wherein:

[0093] Step S110: establishing an electrical connection between the vehicle LIN bus and the target LIN node corresponding to the target vehicle component through the bus interface.

[0094] Specifically, the bus interface of the calibration monitoring development board is used to establish an electrical connection between the vehicle LIN bus and the target LIN node corresponding to the target vehicle component. This step is the basis of the entire calibration and monitoring process, ensuring that the development board can effectively exchange data with the target vehicle component.

[0095] Step S120: Controlling the on / off of the signal between the whole vehicle and the target automobile component through the bus switch to isolate or activate the connection between the whole vehicle and the target automobile component.

[0096] Step S130: measuring electrical parameters on a target LIN node connected to the target automobile component through an electrical data measurement interface.

[0097] Specifically, the electrical parameters of the target LIN node connected to the target automotive component are measured through the electrical data measurement interface. These parameters include key indicators such as current and voltage, which are crucial for evaluating the operating status of the target automotive component.

[0098] Step S140: Analyze the electrical parameters to monitor the operating status of the target automobile component.

[0099] Specifically, the electrical parameters measured in the previous step are analyzed to monitor the operating status of the target automotive component. This analysis process involves real-time processing of data and comparison of historical data to identify any anomalies or trends to ensure that the performance of the target automotive component meets expectations.

[0100] Step S150: Calibrate or adjust the target automobile component according to the monitoring result.

[0101] Specifically, necessary calibration or adjustment operations are performed on the target vehicle components. This step includes firmware updates, parameter adjustments, or other optimization measures to ensure that the target vehicle components can operate in the best condition.

[0102] In this implementation, the method not only improves the efficiency of calibration and monitoring of automobile components, but also enhances the reliability and safety of automobile systems. The application of this method enables technicians to quickly respond to any abnormal conditions of automobile components and make timely adjustments, thereby optimizing the performance and maintenance process of the automobile.
