[0025] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0026] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0027] First, some nouns or terms that appear in the description of the embodiments of the present application are subject to the following interpretations:

[0028] Automatic Brake Prefill (ABP) is a function that pre-charges the brake system, applying brake pressure to reduce the gap between the brake disc and friction pad. When the driver subsequently applies the brake pedal, effective brake pressure is immediately applied, reducing braking response time and, consequently, stopping distance.

[0029] Automatic Warning Brake (AWB) is a forward collision warning system function triggered by a higher-level controller. It generates a brief, noticeable braking force as a warning signal to the driver, alerting them to dangerous traffic conditions or potential accidents and urging them to drive safely. The higher-level controller can adjust the appropriate AWB warning level based on traffic conditions. The brief, forceful warning signal is generated by the dynamic active pressure increase and subsequent pressure release of the braking system. Once the driver steps on the brake pedal, AWB will deactivate. If the driver does not step on the brake pedal and the preset hold time is exceeded, the brake pressure is automatically released.

[0030] Automatic Emergency Braking (AEB) is a feature of the forward collision warning system. It is a safety feature detected and triggered by the upper controller. When the upper controller identifies that the vehicle is in an emergency situation and the driver does not brake accordingly, the AEB function is triggered and executed by the brake control module. The vehicle automatically applies the brakes to reduce the risk of a collision.

[0031] According to an embodiment of the present application, an embodiment of a method for determining the operating status of a braking control system in a vehicle is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0032] Figure 1 FIG is a flow chart of a method for determining the operating state of a braking control system in a vehicle according to an embodiment of the present application. Figure 1 As shown, the method may include the following steps:

[0033] Step S102 : determining the system type of the braking control system in the vehicle and the driving function type used to test the braking control system.

[0034] In the technical solution provided in the above step S102 of the present application, the above-mentioned braking control system can be a control system to be tested, an integrated braking control system (IBCS), a core hub connecting the autonomous driving system and other vehicle systems, and can be used to receive braking signals from the autonomous driving controller or the driver's braking input to parse these signals and convert them into actions suitable for the braking system to perform, such as adjusting hydraulic pressure, controlling braking force, etc. The above-mentioned system type can be used to characterize the type corresponding to the above-mentioned braking control system, and can be a type such as the model of the braking control system. For example, it can include traditional mechanical hydraulic braking systems, electronically assisted braking systems, wire-controlled braking systems, integrated braking control systems, regenerative braking systems, etc. The above-mentioned driving function types can include driving function types such as automatic brake pre-charging, automatic brake warning, and automatic emergency braking. It should be noted that this is only an example, and there is no specific limitation on the system type and driving function type.

[0035] Optionally, when the brake control system needs to be tested, the system type of the brake control system and the type of driving function to be tested on the brake control system may be determined.

[0036] Optionally, by supporting features such as automatic brake pre-charge, automatic brake warning, and automatic emergency braking, the brake control system can anticipate potential collision risks and respond quickly, thereby reducing or avoiding traffic accidents and significantly improving driving safety. The brake control system can seamlessly collaborate with other vehicle sensors and technologies to provide necessary braking interventions, enabling the vehicle to operate autonomously in complex environments.

[0037] Optionally, there can be multiple types of brake control systems, including but not limited to: traditional hydraulic brake systems, which rely on hydraulic oil to transmit braking force and are operated through the brake pedal; electronically assisted brake systems, which add an electronic control unit to the traditional system and can provide functions such as ABS anti-lock braking and EBD electronic brake force distribution; integrated brake control systems, which integrate traditional and electronic braking functions into one, and can better support the special braking needs of autonomous driving and intelligent connected vehicles.

[0038] During the testing phase, because different types of systems may have different testing methods and standards, it is important to clarify the type of brake control system the vehicle is equipped with. For example, due to its integrated nature, the integrated brake control system requires testing not only its braking performance but also its ability to work collaboratively with intelligent connected functions, such as communication stability with the autonomous driving controller and intelligent decision-making during emergency braking.

[0039] Step S104: Obtain a test script that matches the system type and driving function type.

[0040] In the technical solution provided in the above step S104 of the present application, the above test script can be pre-constructed based on the system type and driving function type, and can be used to test the braking control system. For example, it can be a script file corresponding to data such as "the driver presses the brake pedal and the time interval from the last exit of AEB intervention in the same driving cycle is greater than 20 seconds, and the master cylinder pressure is ≥15 Pa, and the AEB function is triggered." It should be noted that this is only an example, and there is no specific restriction on the content and construction method of the test script.

[0041] Optionally, after determining the system type and driving function type of the braking control system, a test script corresponding to the system type and driving function type can be pre-called from the database, and the performance of the braking control system to be tested can be tested using the test script.

[0042] For example, based on the IBCS system type and the selected ABP and AEB driving functions, corresponding test scripts can be retrieved from the test script library. These scripts pre-define a series of test scenarios, such as simulated emergency braking conditions and the response time of pre-charge commands, to verify the performance of IBCS under these two functions.

[0043] Optionally, the above-mentioned test script can be a programming or configuration file used in software testing or automated testing, which can be used to automatically execute a series of predefined test steps and conditions, can be used to verify the functions, performance and reliability of software, systems or hardware, can include the input data, operation steps, expected results and possible boundary conditions of the test case, and can repeatedly execute the same test process, thereby improving the efficiency and consistency of the test.

[0044] Step S106, retrieve the simulation model corresponding to the vehicle and run the test script to obtain simulation data, wherein the simulation model is used to simulate the data transmission process of the vehicle under different driving functions, and the simulation data is used to characterize the response results of the controller in the vehicle under the driving functions.

[0045] In the technical solution provided in the above step S106 of the present application, the simulation model can be a model constructed in advance based on different driving functions, can include controllers and other devices required under different driving functions, can be a simulation integrated brake control system driving interface test node, and can include sensors and request models. The sensors can include high-voltage signals, gear sensors, drive torque sensors, rotation speed sensor board card simulation rotation speed, steering, and rear wheel steering interface simulation. The request models can include automatic brake pre-charge request models, automatic brake warning request models, automatic emergency brake request models, and the like. It should be noted that this is only an example and the type and content of the simulation model are not specifically limited. The simulation data can be data obtained by running the test script by the simulation model, and can be input data of the integrated control system.

[0046] Optionally, after determining the test script required for testing based on the system type and the driving function type, the simulation software corresponding to the vehicle can be called, which can be pre-constructed software. Based on the simulation software, the test script can be run to obtain simulation data. The simulation data can be input as input data into the brake control system to complete the testing of the brake control system.

[0047] For example, the simulation model of the vehicle can be used to run the test script. The simulation model can be a virtual vehicle environment that can simulate the data transmission process of the vehicle under different driving functions, such as sensor data, driver input, and the expected response of the IBCS. Taking AEB as an example, the simulation script can simulate a sudden obstacle to see whether the IBCS can correctly identify the obstacle and brake in time. It should be noted that the simulation model can be updated according to actual conditions, and the construction content of the simulation model is not specifically limited.

[0048] Optionally, using the simulation model and the test script, simulation data of at least one controller in the vehicle under different driving functions can be determined.

[0049] In step S108, the simulation data is input into the brake control system for simulation testing to obtain control data output by the brake control system.

[0050] In the technical solution provided in the above step S108 of the present application, the control data can be data output by the brake control system for controlling the driving of the vehicle.

[0051] Alternatively, simulation data can be fed into the brake control system for simulation testing. This process simulates the brake system's response under various driving conditions, allowing system performance to be evaluated in a safe and controlled environment. The resulting "control data" is the result of decisions or operational commands made by the brake control system based on the received simulation data.

[0052] For example, the above control data can be a pre-charge command, a brake force distribution command (Brake Force Distribution Command), a brake light control command (Brake Light Control Command), a brake release command (Brake Release Command), a warning or error report (Warning or Error Report), etc. It should be noted that this is only an example, and there is no specific restriction on the content of the control data. In the automatic brake pre-charge (ABP) function test, when the simulation data simulates that the driver is about to step on the brake pedal or the system predicts that there will be an imminent braking demand, the brake control system may issue a pre-charge command in advance, that is, instruct a part of the brake system (such as the master cylinder) to start building a certain pressure to reduce the brake response delay time. The control data shows the start time of the pre-charge, the pressure value and its changing trend, etc.

[0053] Optionally, during Automatic Emergency Braking (AEB) functional testing, simulation data may simulate the sudden appearance of an obstacle ahead. Based on factors such as vehicle speed and distance, the braking control system calculates and issues braking force distribution commands, determining the specific amount of braking force to be applied to each braking area, such as the front and rear wheels, and the left and right wheels, to achieve the most stable braking posture. Control data includes information such as the braking force ratio between the front and rear axles and the braking force applied to each wheel. Alternatively, when the braking system detects the start of braking, it triggers a brake light control command, illuminating the vehicle's rear brake lights to warn vehicles behind. Control data records the moment the brake lights illuminate and how long they last.

[0054] Optionally, by analyzing control data, the performance of the brake control system in emergency braking scenarios, such as response speed, braking effect, system stability, and fault handling capabilities, can be evaluated to ensure that the system can reliably respond to emergencies and ensure driving safety during real driving.

[0055] For example, simulation data can be fed into an actual IBCS to observe its actual response. This process, which might be conducted in a laboratory environment, involves connecting a simulator to the actual braking system to test whether the system can correctly output braking force or pre-charge commands based on scenarios generated by the simulation data, ensuring that the vehicle can brake quickly and safely in simulated emergency situations.

[0056] Step S110 : determining the operating state of the brake control system based on the control data.

[0057] In the technical solution provided in step S110 of the present application, the operating state of the brake control system can be determined by judging the control data, and the operating state can include a normal operating state and an abnormal operating state.

[0058] Optionally, the system's operating status is analyzed and determined based on the control data output by the IBCS. This analysis may include checking whether the braking response time meets expectations, whether the system initiates the ABP or AEB function promptly, and whether the braking force is appropriate. For example, if, during an AEB test, the system identifies an obstacle and initiates braking within 0.5 seconds, this indicates that the IBCS's emergency braking function is operating properly. It should be noted that this is merely an example and does not impose any specific limitations on the method for determining the operating status.

[0059] For example, during a test of an autonomous logistics vehicle equipped with IBCS, when entering a warehouse to unload goods, the system initiates pre-braking to prepare for a rapid response to any unexpected situation (such as a worker accidentally entering the vehicle's path). The vehicle's IBCS system type and the ABP function to be tested can be determined. Based on the system type and driving function type, a script matching the ABP function can be retrieved from a test script library. In a virtual simulation environment, the test script can be run using a simulation model to simulate the environment and conditions of the vehicle entering the warehouse, generating a series of simulation data (including simulated sensor signals, vehicle speed, etc.). This simulation data can be input into the actual IBCS to observe whether the pre-charge operation is performed as expected, as well as the magnitude and timing of the pre-charge pressure. Furthermore, based on the actual IBCS output data (such as pre-charge pressure and brake response time), the system's stability, responsiveness, and overall performance under the ABP function can be evaluated to ensure that it can operate safely and effectively in a real-world environment. This allows for comprehensive testing and verification of the IBCS's performance under different driving functions, ensuring that the intelligent connected vehicle's braking system maintains good controllability and safety under various conditions.

[0060] For example, a test program can be launched to simulate the required high-voltage signals, drive torque, wheel speed, gear position, and intelligent driving controller signals. For example, the vehicle position can be set to 50 kilometers per hour, the brake pedal position and the status of the upper controller requesting the AEB function be activated can be set, and the AEB availability status, AEB activation status, and brake light status can be checked. The integrated brake control system triggers the AEB function if the integrated brake control system receives an AEB braking request from the upper controller, the driver presses the brake pedal, and the time interval since the last AEB intervention exit within the same driving cycle is greater than 20 seconds and the master cylinder pressure is ≥15 bar.

[0061] Optionally, this embodiment can conduct a comprehensive and specific test of the driving interface of the brake controller to ensure the logical accuracy of the interactive interface between the driving function and the brake controller, and to ensure the normal use of the advanced intelligent driving function. On the other hand, the integrated braking control system can handle errors and interrupt control in a timely manner to ensure the safety of the driver and to ensure that the driver can take over successfully. And through the construction of automated scripts, the automated testing of the driving interface of the integrated braking control system is realized, which reduces manpower and material resources and improves the efficiency and accuracy of the test. The above is only a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of this application, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the scope of protection of this application.

[0062] The rapid development of intelligent connectivity is driving the future of automobiles towards electrification, intelligence, connectivity, and sharing. Vehicle hardware is being equipped with radar, cameras, and other devices to sense the surrounding environment, while software is being developed to enable assisted and even autonomous driving capabilities. Driving functions are becoming a crucial component of advanced assistance systems (ADAS), such as automatic brake pre-charge, automatic brake warning, and automatic emergency braking. As the actuator for autonomous driving, integrated brake control systems require diverse interface logic to meet the functional requirements of both driver assistance and autonomous driving.

[0063] While driver assistance and autonomous driving have become the hallmarks of the new generation of vehicles, ensuring safety has also become a top priority. Comprehensive testing of the driving interface of the integrated brake control system is essential. Currently, most testing relies on road tests. While these tests can ensure successful interface commissioning, they are difficult to implement under complex and extreme operating conditions to ensure tester safety. On the one hand, a large part of the function of the driving interface of the integrated brake control system is to ensure that when an unforeseen failure occurs in the upper-level autonomous driving controller, the brake control system, as an actuator, can promptly handle the error and interrupt control, ensuring driver safety and enabling successful driver takeover. This prevents situations such as the failure of automatic emergency braking in the event of a collision on a highway. On the other hand, simulation scenarios can be used to test the driving interface under complex user scenarios, ensuring the logical accuracy of the interaction between the driving function and the brake controller, and ensuring the proper operation of advanced intelligent driving features. Furthermore, automated testing on a real vehicle is difficult to implement, requiring significant manpower and resources, and can easily overlook various test conditions.

[0064] To address these issues, this application proposes an engineering device for testing the vehicle interface of an integrated brake control system. This device enables comprehensive testing of brake control system interface requirements, including automatic brake pre-charge, automatic brake warning, and automatic emergency braking, ensuring driving safety under these conditions. This method, through the conversion of real-world vehicle data to simulation, enables automated interface logic testing, conserving resources and ensuring quality.

[0065] Through the above steps S102 and S110 of the present application, the system type of the braking control system in the vehicle and the driving function type for testing the braking control system are determined; a test script matching the system type and the driving function type is obtained; a simulation model corresponding to the vehicle is called to run the test script to obtain simulation data, wherein the simulation model is used to simulate the data transmission process of the vehicle under different driving functions, and the simulation data is used to represent the response results of the controller in the vehicle under the driving functions; the simulation data is input into the braking control system for simulation testing to obtain control data output by the braking control system; and based on the control data, the operating state of the braking control system is determined. That is, in the embodiment of the present application, after determining the integrated braking control system to be tested, a test script corresponding to the braking control system can be determined based on the system type corresponding to the braking control system and the driving function type to be tested, the test script is input into the simulation model to obtain simulation data output by the simulation model, the simulation data is input into the braking control system to be tested for simulation testing to obtain control data output by the braking control system, and the operating state of the braking control system can be determined based on the control data, thereby achieving the technical effect of improving the testing efficiency of the braking system and solving the technical problem of low testing efficiency of the braking system.

[0066] The above method of this embodiment is further introduced below.

[0067] As an optional implementation, step S106, calling the simulation model corresponding to the vehicle to run the test script to obtain simulation data, includes: calling the simulation model that matches the driving function type; using the called simulation model to run the test script to obtain simulation data.

[0068] In this embodiment, the simulation model may be pre-built based on the driving function type. After determining the driving function type, a simulation model matching the driving function type may be retrieved. The retrieved simulation model may then be used to run a test script to obtain simulation data.

[0069] Alternatively, the simulation data may be an AEB braking request issued by a controller in a simulation model. The simulation model may include simulations of nodes and sensors required for integrated braking control system interface testing, as well as test function models for automatic brake pre-charge, automatic brake warning, and automatic emergency braking.

[0070] As an optional implementation, the test script is run using the retrieved simulation model to obtain simulation data, including: running the test script using the sensors in the simulation model to obtain simulation data output by the sensors, and / or retrieving the request model in the simulation model to run the test script to obtain simulation data output by the request model, wherein the request model and the driving function correspond one to one.

[0071] In this embodiment, the sensor in the simulation model can be used to run the test script to obtain the simulation data output by the sensor. The simulation data can be the high-voltage signal, gear position, driving torque, wheel speed of the wheel speed sensor, steering, rear wheel steering and other data obtained by simulation. It should be noted that this is only an example, and there is no specific restriction on the data type of the sensor output. While obtaining the simulation data output by the sensor, the request model in the simulation model can be scheduled to run the test script to obtain the simulation data output by the request model. The request model can be pre-built based on the driving function and has a one-to-one correspondence with the driving function. It can include an automatic braking pre-charge request model, an automatic braking warning request model and an automatic emergency braking request model. It should be noted that this is only an example, and there is no specific restriction on the type of request model.

[0072] In this embodiment, an integrated braking control system automatic driving interface testing device and method are proposed. The method may include two parts: an integrated braking control system automatic driving interface testing device and an automated testing method. Figure 2 Schematic diagram of an integrated braking control system automatic driving interface test device according to an embodiment of the present application. Figure 2 As shown, the device may include: a test device 201, a bus monitoring tool 202, an integrated brake control system assembly 203, and a DC power supply 204. It should be noted that this is only an example and does not specifically limit the devices included in the test device.

[0073] Optionally, the test equipment 201 may include an integrated brake control system vehicle interface test node and sensor simulator 2011. The DC power supply may be a 12V DC power supply. The integrated brake control system may be generally referred to as a brake control system, and data communication with a bus monitoring tool may be performed via a controller area network (CAN_L, CAN_H) bus.

[0074] Figure 3is a schematic diagram of a simulation model according to an embodiment of the present application, such as Figure 3 As shown, the simulation model can simulate the driving interface test interface and sensor simulation of the integrated braking control system, and may include: high-voltage signal, gear position, driving torque simulation 311, wheel speed sensor board simulation wheel speed 312, steering, rear wheel steering interface simulation 313, and driving intelligent driving controller simulation 314. The driving intelligent driving controller simulation 314 may include multiple request models, for example, it may include automatic brake pre-charge request model simulation 3141, automatic brake warning request model simulation 3142, automatic emergency brake request model simulation 3143, etc.

[0075] As an optional implementation, step S110 determines the operating status of the braking control system based on the control data, including: determining the standard control data corresponding to the braking control system under the driving function type; matching the control data and the standard control data to obtain a matching result; and determining the operating status based on the matching result.

[0076] In this embodiment, standard control data corresponding to different driving function types of the brake control system can be determined in advance. After the control data is obtained through testing, the standard control data corresponding to the brake control system for the driving function type can be retrieved. The standard control data can be matched with the control data to obtain a matching result, and the operating status of the brake control system can be determined based on the matching result.

[0077] As an optional implementation, determining the operating state based on the matching result includes: in response to the matching result being used to characterize that the control data and the standard control data do not match successfully, determining that the operating state is an abnormal operating state.

[0078] In this embodiment, if the matching result for the characterizing control data and the standard control data does not match successfully, the operating state may be determined to be an abnormal operating state.
