[0063] It should be noted that the "at..." in the embodiments of the present application can be the instant when a certain situation occurs, or can be a period of time after a certain situation occurs, and the embodiments of the present application do not specifically limit this. In addition, the test method of the accelerator mis-stepping warning system provided in the embodiments of the present application is only used as an example, and the test method of the accelerator mis-stepping warning system can also include more or less content.

[0064] In order to clearly describe the technical solutions of the embodiments of the present application, some terms and technologies involved in the embodiments of the present application are briefly introduced below:

[0065] Accelerator Misoperation Warning System: Also known as Accelerator Misoperation Prevention System or Accelerator Misoperation Correction System, it is a vehicle safety assistance system. Its main function is to improve driving safety, especially when the driver may mistake the accelerator for the brake pedal due to nervousness, negligence or other reasons.

[0066] With the continuous development of automobile technology, the safety performance of vehicles has attracted more and more attention. Accelerator misoperation is a common factor causing traffic accidents, and the accelerator misoperation warning system can effectively reduce the incidence of traffic accidents caused by misoperation and ensure the safety of occupants, pedestrians and other vehicles around. Therefore, the accurate response and response speed of the accelerator misoperation warning system are particularly important to ensure driving safety.

[0067] However, there is no unified standard for the test method of the accelerator misoperation warning system in the prior art, which makes it difficult to directly and effectively compare the performance of accelerator misoperation warning systems of different brands and models. In order to promote technological progress and improve the level of road traffic safety, it is particularly urgent to establish a set of standardized testing processes and evaluation systems.

[0068] Based on this, the embodiment of the present application proposes a test method, device, equipment, medium and product for the accelerator mis-stepping warning system, which can be used in the field of automobile safety testing technology, aiming to solve the above technical problems of the prior art. By setting a set of common evaluation indicators to establish a unified standard for the test results of the accelerator mis-stepping warning system, the performance of the accelerator mis-stepping warning system can be comprehensively analyzed and evaluated, ultimately improving the driving safety of the vehicle and ensuring the safety of the occupants, surrounding pedestrians and other vehicles.

[0069] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0070] Figure 1 A flow chart of a test method for a throttle mis-stepping warning system provided in an embodiment of the present application Figure 1 .like Figure 1 As shown, the method includes:

[0071] S101. Acquire multiple status data of a test vehicle after simulating an accidental accelerator pedal stepping event.

[0072] In an embodiment of the present application, the executor of a test method for an accelerator mis-stepping warning system may be a server, which may be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server, etc., without specific limitation.

[0073] Specifically, after obtaining multiple status data of the test vehicle after simulating the accidental accelerator pedaling event, the server can preprocess the multiple status data, including but not limited to data cleaning, eliminating outliers or filling missing values, etc., to remove outliers in the multiple status data.

[0074] Among them, each status data corresponds to a moment, and the status data includes at least one of the following: the speed of the test vehicle, the distance between the test vehicle and the obstacle in front, the relative speed between the test vehicle and the obstacle in front, the accelerator pedal opening of the test vehicle, and the response information of the accelerator mistakenly pressing warning system. The accelerator mistakenly pressing warning system is installed on the test vehicle.

[0075] In addition, the status data can be derived from both virtual simulation tests and real vehicle tests, and there is no specific restriction here. Virtual simulation tests refer to the test of the accelerator mis-step warning system triggering the warning function according to the virtual driving scene simulated by simulation software and CANOE and other tools; real vehicle tests include the construction of test scenes, the preparation of test vehicles and front obstacles (vehicles, pedestrians and other objects), etc. Inertial navigation equipment can be installed on the test vehicle and the front obstacle vehicle, and triangular cones or other marks that are easy for the inertial navigation equipment to identify can be equipped on the front obstacle vehicle to accurately measure the distance and relative speed between the test vehicle and the front obstacle vehicle. Or by installing radar and / or cameras on the test vehicle to determine the distance between the test vehicle and the front obstacle and identify the type of obstacle. Or by installing a laser rangefinder on the test vehicle to calculate the distance between the test vehicle and the front obstacle by emitting a laser beam and measuring the time it takes for it to reflect back. In the test scenario, the simulated accelerator mis-step event can be achieved through a preset control system or by intentional misoperation by the driver.

[0076] S102: Calculate evaluation result data of the accelerator mis-stepping warning system according to the status data.

[0077] In an embodiment of the present application, the evaluation result data includes at least one of the following: response delay, false response rate, missed response rate and obstacle type coverage.

[0078] Specifically, the server can calculate the response delay and / or false response rate and / or missed response rate and / or obstacle type coverage of the accelerator mistakenly pressing warning system according to the acquired status data, so as to comprehensively analyze the performance of the accelerator mistakenly pressing warning system, thereby improving the driving safety of the vehicle.

[0079] The present embodiment provides a testing method for an accelerator mistakenly pressed warning system, the method comprising: obtaining multiple status data of a test vehicle after a simulated accelerator mistakenly pressed event, each status data corresponding to a moment, the status data comprising at least one of the following: the speed of the test vehicle, the distance between the test vehicle and a front obstacle, the relative speed between the test vehicle and the front obstacle, the accelerator pedal opening of the test vehicle, and response information of the accelerator mistakenly pressed warning system, the accelerator mistakenly pressed warning system being installed on the test vehicle; calculating evaluation result data of the accelerator mistakenly pressed warning system based on the status data, the evaluation result data comprising at least one of the following: response delay, false response rate, missed response rate, and obstacle type coverage.

[0080] The following technical effects are achieved: evaluation result data of the accelerator mistakenly pressing warning system is calculated based on the status data of the test vehicle, and then the overall performance of the accelerator mistakenly pressing warning system can be comprehensively analyzed and evaluated based on the response delay and / or false response rate and / or missed response rate and / or obstacle type coverage of the accelerator mistakenly pressing warning system, thereby improving the driving safety of the vehicle and ensuring the safety of occupants and surrounding pedestrians and vehicles; in actual vehicle testing, by installing inertial navigation equipment on the test vehicle and the obstacle vehicle in front, the distance and relative speed between the test vehicle and the obstacle vehicle in front can be accurately measured, so that the acquired status data of the test vehicle is more accurate, thereby improving the test accuracy of the accelerator mistakenly pressing warning system.

[0081] Figure 2 A flow chart of a test method for a throttle mis-stepping warning system provided in an embodiment of the present application Figure 2 In one possible example, Figure 2 As shown, in this embodiment Figure 1 Based on the embodiment, how to calculate the evaluation result data of the accelerator mis-stepping warning system according to the state data is described in detail. Figure 2 As shown, the method includes:

[0082] S201. Acquire multiple status data of the test vehicle after simulating an accidental accelerator pedal stepping event.

[0083] S201 is similar to S101 and will not be described in detail in this embodiment.

[0084] S202: extracting, from the plurality of state data, a plurality of state sub-data of the test vehicle after simulating an accelerator mis-stepping event in each test scenario.

[0085] In the embodiment of the present application, the test scenario corresponds to at least one of the following test scenario parameters: road shape, driving speed, road slope, obstacle type, accelerator mis-pressing duration, and accelerator mis-pressing degree. Among them, the road shape includes scenes such as straight-line driving and curve driving; the driving speed includes multiple driving speeds of different sizes; the road slope includes uphill scenes of different slopes and downhill scenes of different slopes; the obstacle type includes all kinds of motor vehicles, non-motor vehicles, pedestrians and other objects; the accelerator mis-pressing duration includes multiple different pedaling test durations; the accelerator mis-pressing degree corresponds to multiple different vehicle accelerations.

[0086] Specifically, the evaluation result data of the accelerator mis-stepping warning system is calculated based on the state data, including: according to a plurality of different test scenarios set in advance, in each test scenario, respectively, extracting a plurality of state sub-data after the simulated accelerator mis-stepping event of the test vehicle corresponding to different test scenarios from the acquired multiple state data. So that the server can calculate the evaluation result data of the accelerator mis-stepping warning system in each test scenario based on the multiple state sub-data of the simulated accelerator mis-stepping event of the test vehicle in each test scenario.

[0087] S203. Determine the importance of each evaluation result data.

[0088] In the embodiment of the present application, the meanings of the four evaluation result data are as follows:

[0089] The response delay is the time difference between the moment when the status data meets the warning conditions and the time when the accelerator mis-step warning system sends the corresponding warning information. The warning conditions include at least one of the following: the distance between the test vehicle and the obstacle ahead is less than or equal to the warning distance corresponding to the vehicle speed, the relative vehicle speed is greater than or equal to the warning speed, and the accelerator pedal opening is greater than the warning opening. Among them, the relative vehicle speed is greater than or equal to the warning speed, which means that the speed difference between the test vehicle speed and the obstacle vehicle ahead is greater than or equal to the safe speed difference, and the test vehicle speed is greater than the speed of the obstacle vehicle ahead.

[0090] The false response rate refers to the probability that the accelerator mis-step warning system sends a corresponding warning message even though the status data does not meet the warning conditions.

[0091] The missed response rate refers to the probability that the status data meets the warning conditions but the accelerator mis-step warning system does not send the corresponding warning information.

[0092] The obstacle type coverage rate refers to the percentage of obstacle types when the response accuracy of the accelerator mis-step warning system meets the preset response rate threshold. The response accuracy rate is calculated based on the missed response rate and the false response rate. Specifically, the response accuracy rate = 1-false response rate-missed response rate. The obstacle types include all types of motor vehicles, non-motor vehicles, pedestrians and other objects. Other objects refer to obstacles other than all types of motor vehicles, non-motor vehicles and pedestrians.

[0093] When the server calculates the evaluation result data of the accelerator warning mis-stepping system in different test scenarios, first, the importance of each evaluation result data can be determined according to the preset evaluation index in each test scenario.

[0094] Table 1 Evaluation index table of accelerator mis-step warning system

[0095]

[0096] Table 1 schematically shows a set of evaluation indicators for the accelerator mis-stepping warning system. The importance of each evaluation result data in each test scenario can be determined according to the scoring criteria in Table 1. The higher the score, the more important the evaluation result data. In this embodiment, the four evaluation result data of response delay, false response rate, missed response rate and obstacle type coverage are all set with the same weight. Therefore, the same weight is set for these four evaluation result data (the full score of each evaluation result data is 25 points).

[0097] In addition, in a possible implementation, different evaluation indicators can be set for different test scenarios. For example, for a test scenario where the test scenario is downhill driving, it can be determined that the importance of response delay is the highest, the importance of false response rate is second, the importance of missed response rate is third, and the importance of obstacle type coverage is set to the lowest, and correspondingly, different weights are set for different evaluation result data in order of importance. Specifically, the full score of the response delay part is set to 40 points, the full score of the false response rate part is set to 25 points, the full score of the missed response rate part is set to 20 points, and the full score of the obstacle type coverage part is set to 15 points.

[0098] S204. For each test scenario, weighted sum is performed on multiple evaluation result data of the accelerator mis-stepping warning system when the test vehicle simulates an accelerator mis-stepping event in each test scenario according to the importance, so as to obtain the evaluation result data of the accelerator mis-stepping warning system in each test scenario.

[0099] Specifically, for each test scenario, that is, when the test vehicle simulates an accidental accelerator pedaling event in each test scenario, the server can perform a weighted summation of multiple evaluation result data of the accidental accelerator pedaling warning system in each test scenario according to the importance of each evaluation result data, thereby obtaining the evaluation result data of the accidental accelerator pedaling warning system in each test scenario.

[0100] S205: Obtain the weight of each test scenario.

[0101] S206 , performing weighted summation on the evaluation result data of the accelerator mis-stepping warning system under multiple test scenarios according to the weights of the test scenarios, to obtain a comprehensive evaluation result of the test vehicle.

[0102] Specifically, after calculating the evaluation result data of the accelerator misoperation warning system in each test scenario, the server can further obtain the pre-set weight of the test vehicle in each test scenario. According to the weight of each test scenario, the evaluation result data of the accelerator misoperation warning system in multiple test scenarios are weighted and summed, thereby obtaining the comprehensive evaluation result of the accelerator misoperation warning system installed in the test vehicle.

[0103] S207: When the evaluation result data and / or the comprehensive evaluation result do not meet the preset conditions, generate optimization suggestions for the accelerator mis-stepping warning system according to the evaluation result data.

[0104] In an embodiment of the present application, the preset conditions include at least one of the following: the response delay is greater than or equal to the preset time length threshold, the false response rate is greater than or equal to the preset false response rate threshold, the missed response rate is greater than or equal to the preset missed response rate threshold and the obstacle type coverage is less than or equal to the preset coverage threshold, and the comprehensive evaluation result is less than or equal to the preset threshold.

[0105] Specifically, when the evaluation result data shows that the response delay is greater than or equal to the preset time threshold, and / or the false response rate is greater than or equal to the preset false response rate threshold, and / or the missed response rate is greater than or equal to the preset missed response rate threshold, and / or the obstacle type coverage is less than or equal to the preset coverage threshold, and / or the comprehensive evaluation result is less than or equal to the preset threshold, the server can generate optimization suggestions for the accelerator mis-step warning system based on the evaluation result data. The optimization suggestions are used to indicate the adjustment of the warning conditions and perception system of the accelerator mis-step warning system to improve the overall performance of the accelerator mis-step warning system, thereby improving the safety of the vehicle.

[0106] S208. Generate an evaluation report of the accelerator mis-step warning system according to the test scenario parameters, status data, evaluation result data, comprehensive evaluation results, and optimization suggestions.

[0107] Specifically, the server can generate a detailed evaluation report after comprehensive testing of the accelerator mis-operation warning system based on multiple test scenario parameters, multiple status data, multiple evaluation result data, and the final comprehensive evaluation results and optimization suggestions. In the evaluation report, the multi-dimensional test results of the accelerator mis-operation warning system in each test scenario can be visualized through charts, curves, etc., so that the test personnel can intuitively understand the overall performance of the accelerator mis-operation warning system.
