[0048] S101. Acquire actual driving data of a vehicle to be tested.

[0049] Vehicles are usually equipped with a variety of sensors, such as speed sensors, GPS sensors (global positioning system sensors), etc. These sensors can monitor and record the speed, position and heading angle of the vehicle (i.e. the direction of the vehicle's travel) in real time. The speed sensor can measure the rotation speed of the wheels or the acceleration of the vehicle to calculate the actual speed of the vehicle. The GPS sensor can receive signals from multiple satellites and determine the three-dimensional position (longitude, latitude and altitude) of the vehicle by calculating the propagation time of these signals. The heading angle of the vehicle can usually be measured by analyzing the motion trajectory in the GPS data or using a dedicated heading sensor. The heading angle represents the angle between the direction of the vehicle's travel and a reference direction (such as due north).

[0050] In addition to on-board sensors, external monitoring systems (such as traffic monitoring cameras, radar systems, etc.) can also be used to monitor and record vehicle driving data. This method is usually used in scenarios such as traffic management and security monitoring, and can also be used for vehicle testing.

[0051] Collecting this real-time data is critical to evaluating the performance, safety, and effectiveness of the vehicle's driver assistance systems. During the vehicle testing phase, this data can help engineers identify potential problems, optimize the vehicle's design and control systems, and ensure that the vehicle performs well under a variety of driving conditions.

[0052] S102, inputting the actual driving data into a dummy model that has been pre-trained based on machine learning; the dummy model is used to simulate the pedestrian's reaction, crossing action and speed when facing a vehicle.

[0053] The actual driving data includes real-time data such as speed, position and heading angle obtained from the vehicle, which reflects the driving status of the vehicle at a specific moment.

[0054] The pre-trained dummy model is trained using machine learning techniques to simulate pedestrians’ various reactions, crossing movements, and walking speeds when facing vehicles. The training of the model usually involves the collection and analysis of a large amount of pedestrian behavior data, and the use of this data to optimize the model’s predictive capabilities.

[0055] The actual driving data is fed into the dummy model, which then simulates the likely behavior of pedestrians based on the data. For example, if the vehicle is approaching a location where a pedestrian might cross, the model can predict whether the pedestrian will choose to cross, when, and at what speed.

[0056] By using a dummy model to simulate real-world pedestrian behavior, the performance of the vehicle's automatic emergency braking (AEB) system or other driver assistance systems can be evaluated in complex scenarios such as pedestrians crossing the road. By combining actual driving data with simulated pedestrian behavior, a test environment close to the real world can be created, which is crucial for verifying the safety and reliability of vehicle systems.

[0057] S103: Based on the actual driving data and the historical collision data in the dummy model pre-trained based on machine learning, control the dummy model to perform an avoidance or crossing action according to the operation status of the vehicle.

[0058] Combine the actual driving data of the vehicle to be tested (such as speed, position and heading angle) with the historical collision data in the dummy model. The historical collision data may contain pedestrian behavior patterns in a variety of scenarios, such as pedestrian reactions and actions at different speeds and distances. Based on this data, the system or model will make a decision to determine whether the dummy model should perform an evasive action or a crossing action. This decision-making process may involve complex algorithms and logic to ensure that the simulated pedestrian behavior is both realistic and representative. Once the decision is made, the dummy model will perform the corresponding action based on the decision result, such as stopping to avoid the vehicle or continuing to cross the road.

[0059] When the dummy model triggers the crossing action, it usually means that a potential collision scenario has occurred or is about to occur. At this time, the system will record the vehicle information (such as model, speed, etc.), collision information (such as collision location, collision intensity, etc.) of the vehicle to be tested, and the crossing information of the dummy model (such as crossing speed, crossing location, etc.). This information together constitutes a complete record of the test results for subsequent analysis and evaluation.

[0060] By simulating real-world pedestrian behavior, the performance of the vehicle under test in potential collision scenarios is evaluated. By recording and analyzing the test results, the vehicle's response and safety in complex scenarios such as pedestrians crossing can be understood, thus providing valuable feedback for vehicle design and improvement.

[0061] The above embodiment introduces the process of testing the automatic emergency braking system of a vehicle based on a pre-trained dummy model and the actual driving data of the vehicle to be tested. In the implementation process of the above method, before the dummy model is trained, the method also includes: obtaining pedestrian crossing information in a traffic accident where the vehicle cannot perform emergency braking due to the pedestrian crossing information causing a collision, the pedestrian crossing information including crossing speed, waving speed, and collision position; obtaining vehicle information corresponding to the pedestrian crossing information, including vehicle speed and vehicle model; obtaining environmental information corresponding to the pedestrian crossing information, including the lateral distance and longitudinal distance between the vehicle and the pedestrian, and surrounding environment occlusion information; storing the pedestrian crossing information, vehicle information, and environmental information in a resource library and performing feature marking; establishing a pedestrian crossing collision model based on machine learning, and training the dummy model by simulating and learning the pedestrian's reaction, crossing action, and speed when facing a vehicle.

[0062] To obtain pedestrian crossing information in traffic accidents, we collect collision cases in which pedestrians cross vehicles in real traffic accidents and the vehicles fail to brake urgently. Pedestrian crossing information mainly includes the crossing speed of pedestrians, i.e. the walking speed of pedestrians when crossing the road, the waving speed (pedestrians may wave their hands to indicate that they want to cross), and the collision position (the specific position where the pedestrian and the vehicle come into contact).

[0063] The vehicle information corresponding to the pedestrian crossing information is obtained to understand the specific state of the vehicle when the collision occurs. The vehicle information includes the vehicle speed (the speed at the moment of collision) and the vehicle model (different models may have different braking performance and field of view).

[0064] The environmental information corresponding to the pedestrian crossing information is obtained to analyze the environmental factors when the collision occurs. The environmental information includes the lateral distance between the vehicle and the pedestrian (i.e., the vertical distance between the vehicle and the pedestrian's crossing path), the longitudinal distance (i.e., the relative distance between the vehicle and the pedestrian along the road direction), and the surrounding environmental occlusion information (such as trees, buildings, etc. that may block the driver's line of sight).

[0065] Storing the pedestrian crossing information, vehicle information and environmental information in a resource library can organize the collected information into a usable data set. Specifically, the pedestrian crossing information, vehicle information and environmental information are stored in a resource library, and each piece of data is marked with features for subsequent analysis and model training.

[0066] After completing the above preparations, a pedestrian crossing collision model is established based on machine learning, and a model that can simulate pedestrian crossing behavior is established using machine learning technology. Through simulation, learn the pedestrian's reaction when facing a vehicle (such as whether to choose to cross, when to start crossing), crossing action (such as walking speed, walking trajectory) and speed, and how these factors affect the occurrence of collisions. This model will be trained based on the data in the resource library to optimize its prediction ability. Further train the dummy model so that the dummy model can simulate pedestrian behavior in the real world. Specifically, the behavior of the dummy model is guided by using the trained pedestrian crossing collision model. By continuously adjusting and optimizing the parameters and logic of the dummy model, it can more accurately simulate the reactions and actions of pedestrians when facing vehicles.

[0067] In summary, these steps together constitute a complete dummy model training process. By collecting and analyzing data from real traffic accidents and building a model using machine learning technology, a dummy model that can simulate real-world pedestrian behavior can be trained. This model will be used in subsequent vehicle tests to evaluate the performance and safety of the vehicle when facing complex scenarios such as pedestrians crossing the road.

[0068] In one implementation of the embodiment of the present application, the dummy model can support different function selections to achieve more flexible testing of the AEB system. The optional functions of the dummy model include false triggering function, direct triggering function and parameter matching function with the preset relevant standard and regulatory database. In order to simulate the scenario in the real world where the vehicle may be falsely triggered due to pedestrians crossing, suddenly stopping, turning, etc., a false triggering function is designed for the dummy model to control the dummy model to simulate the test scenario where the vehicle is falsely triggered due to pedestrians crossing, suddenly stopping, turning, etc. By controlling the dummy model to perform these specific actions, the vehicle's sensors and control system can be triggered, thereby evaluating the vehicle's response and performance when facing such complex and unexpected pedestrian behavior.

[0069] In order to directly test the vehicle's automatic emergency braking (AEB) system, a direct trigger function is designed for the dummy model, which is used to control the dummy model to directly perform a traversing action to trigger the vehicle's automatic emergency braking AEB system. By controlling the dummy model to directly perform a traversing action, the vehicle's AEB system can be triggered and its response speed, braking effect, and overall safety can be evaluated.

[0070] In order to ensure that the test process meets specific regulatory certification requirements, a function for matching parameters with a preset standard regulatory database is designed for the dummy model. The function of matching parameters with a preset relevant standard regulatory database is used to control the dummy model to automatically match the corresponding regulatory parameters based on the pre-entered specific regulatory certification requirements, and make corresponding crossing choices based on vehicle speed and other conditions; different test scenarios are generated based on the selected function and the parameter matching results with the preset standard regulatory database. Based on the pre-entered specific regulatory certification requirements, the dummy model can automatically match the corresponding regulatory parameters. For example, according to the regulatory requirements for the vehicle's reaction time or braking distance to pedestrians crossing at different speeds, the dummy model can make corresponding crossing choices.

[0071] After completing the function selection of the dummy model, you can use these functions to generate different test scenarios according to the test requirements and conduct actual vehicle tests. By collecting and analyzing the test results, you can accurately evaluate the performance of the vehicle and provide valuable feedback for vehicle design and improvement.

Based on this, the present application also provides a corresponding system.
