The implementation details of the technical solution of the embodiment of the present application are set forth in detail below:
firstly, it should be noted that the test scheme of the vehicle speed limiting system provided in the application can be applied to the related technical field of automatic driving, the vehicle speed limiting system is generally required to be used in the technical field, the intelligent speed limiting system is a novel intelligent driving auxiliary function, a speed limiting area and a speed limiting sign are identified through a camera and a vehicle-mounted navigation system, a driver is reminded to reduce the speed, and the system reduces the speed after the driver confirms the speed. Therefore, the accuracy of the vehicle speed limiting system in speed limiting control directly influences the automatic driving performance. Therefore, after the vehicle speed limiting system is developed, the test of the vehicle speed limiting system is very important.
According to an aspect of the present application, there is provided a method for testing a vehicle speed limiting system, and fig. 1 is a flowchart illustrating a method for testing a vehicle speed limiting system according to an embodiment of the present application, where the method for testing a vehicle speed limiting system can be executed by a device having a calculation processing function, and the method for testing a vehicle speed limiting system at least includes steps 110 to 140, which are described in detail as follows:
in step 110, simulation data corresponding to at least one speed limiting scene one to one is input to the vehicle speed limiting system to trigger the vehicle speed limiting system to generate a control instruction according to the simulation data.
In the application, any speed limit scene which may occur in the vehicle speed limit system can be listed in advance, for example, the scene that the vehicle identifies any speed limit area at any cruising speed and the driver confirms after requesting to descend. According to the speed-limiting scene, simulation data can be correspondingly determined, and the simulation data can be used for simulating speed-limiting information collected by a vehicle speed-limiting system under the real speed-limiting scene.
In order to make the simulation data better understood by those skilled in the art, the simulation data in several speed limit scenarios will be listed below by tables 1 and 2.
Referring to table 1, several intelligent underspeed control scenarios are listed. For example, "[40;10; 110' may indicate that the lower limit value of the cruising speed value of the vehicle may be 40km/h, the upper limit value may be 110km/h, each acceleration or deceleration amplitude may be 10km/h, and when the speed limit vehicle speed value is 30km/h, the speed limit system needs to control the vehicle to decelerate to 30km/h from the current cruising speed value.
TABLE 1
Further, referring to table 2, several intelligent speed limit reminding scenes are listed. For example, in the scene a, the simulation data sent to the vehicle speed limiting system may be "the vehicle passes through the speed limiting area, and the driver confirms the request", and for the speed limiting system, the system should send out a speed limiting prompt, and the driver sets the vehicle speed to be reduced to the speed limiting value after confirming, and the vehicle is decelerated to the stable speed limiting value.
The intelligent speed limit reminding scene is mainly used for reminding a driver to confirm when a speed limit area (speed limit value) is identified and a speed difference value exceeds a threshold value, the driver can be reminded of flashing a command signal value during initial reminding, and a signal for reminding the driver can be changed into continuous bright reminding after a period of time.
TABLE 2
With continued reference to fig. 1, in step 120, the control command is sent to a test vehicle, and feedback data of the test vehicle executing the control command is obtained.
In the scheme of the speed limiting system, after the vehicle speed limiting system acquires the simulation data corresponding to the speed limiting scene, a control instruction can be generated according to the simulation data, and the control instruction is sent to the test vehicle, so that the test vehicle can execute speed reduction action under the control of the control instruction in the speed limiting scene simulated by the simulation data.
Accordingly, after the control command is sent to the test vehicle, feedback data of the test vehicle for executing the control command can be obtained, wherein the feedback data can reflect the actual execution condition of the vehicle for executing the control command and can indirectly test the performance of the vehicle deceleration system.
With continued reference to FIG. 1, at least one evaluation index for the vehicle speed limit system is obtained at step 130.
In the present application, at least one evaluation index for the vehicle speed limit system may be formulated in advance. Different evaluation indexes can test the performance of the vehicle speed limiting system from different angles.
In the present application, the evaluation index may include at least: whether the vehicle state diagnosis function is normal or not, whether the speed limit reminding function is normal or not, whether the vehicle speed value setting function is normal or not and the vehicle speed control precision.
The evaluation index for judging whether the vehicle state diagnosis function is normal mainly tests the performance of the vehicle speed limiting system in the aspect of judging the vehicle state, generally, when the vehicle is subjected to speed limiting control, the vehicle speed limiting system needs to judge the state of the vehicle (for example, judge whether a vehicle door is in a normal closed state), if the state is judged to be normal, speed limiting operation is carried out, and if the state is judged to be abnormal, the speed limiting operation is stopped. In the test scene, the actual state of the vehicle is normal, and if the vehicle speed limiting system diagnoses that the vehicle state is abnormal in the test process, the problem of the vehicle speed limiting system is proved.
The evaluation index for judging whether the speed limit reminding function is normal mainly tests whether the vehicle speed limit system reminds a user of limiting the speed when the vehicle cruising speed value exceeds the speed limit value, and particularly, under the normal condition, when the speed difference value between the current cruising speed value and the speed limit value of the vehicle exceeds a threshold value, the vehicle speed limit system shall remind the driver of limiting the speed.
The evaluation index for judging whether the vehicle speed value setting function is normal mainly tests whether the vehicle speed limiting system sets the speed value same as the speed limit value after a driver confirms a speed limit request sent by the vehicle speed limiting system.
The evaluation index of the vehicle speed control accuracy mainly tests the control accuracy of the vehicle speed limiting system on the actual speed of the vehicle according to the set vehicle speed value, for example, after the set vehicle speed value is determined to be controlled to be 40km/h, the vehicle speed limiting system controls the running speed of the vehicle to be 40 km/h.
With continued reference to FIG. 1, in step 140, the vehicle speed limit system is tested for a level of trafficability under various speed limit scenarios by the at least one evaluation indicator based on the feedback data.
In one embodiment of the application, the step of testing the trafficability level of the vehicle speed limit system under various speed limit scenarios by the at least one evaluation index based on the feedback data may be performed as shown in fig. 2.
Referring to fig. 2, a detailed flowchart illustrating a method for testing the passing level of the vehicle speed limiting system under various speed limiting scenarios through the at least one evaluation index based on the feedback data according to an embodiment of the present application is shown.
Specifically, the method comprises steps 141 to 142:
And 142, calculating a comprehensive evaluation score based on the evaluation scores corresponding to the evaluation indexes, wherein the comprehensive evaluation score is used for representing the trafficability level of the vehicle speed limiting system in the target speed limiting scene.
In this embodiment, each evaluation index is scored through feedback data corresponding to the target speed limit scene to obtain an evaluation score, and each evaluation index may be specifically scored according to the following scheme.
First, if it is determined that the vehicle state diagnosing function is normal through the feedback data, the evaluation score for whether the vehicle state diagnosing function is normal is 1 score, and if it is determined that the vehicle state diagnosing function is abnormal through the feedback data, the evaluation score for whether the vehicle state diagnosing function is normal is 0 score.
Secondly, if the speed limit reminding function is determined to be normal through the feedback data, the evaluation score for judging whether the speed limit reminding function is normal is 1, and if the speed limit reminding function is determined to be abnormal through the feedback data, the evaluation score for judging whether the speed limit reminding function is normal is 0.
Third, if it is determined through the feedback data that the vehicle speed value setting function is normal, the evaluation score of whether the vehicle speed value setting function is normal is 1 score, and if it is determined through the feedback data that the vehicle speed value setting function is abnormal, the evaluation score of whether the vehicle speed value setting function is normal is 0 score.
Fourthly, if the vehicle speed control precision x is determined to meet x < akm/h through the feedback data, the evaluation score aiming at the vehicle speed control precision is 1 score, if the vehicle speed control precision x is determined to meet x < akm/h and x < bkm/h through the feedback data, the evaluation score aiming at the vehicle speed control precision is a set evaluation score, if the vehicle speed control precision x is determined to meet x > bkm/h through the feedback data, the evaluation score aiming at the vehicle speed control precision is 0 score, wherein 0 < the set evaluation score is < 1.
In order to make the above evaluation indexes better understood by those skilled in the art, the following description will be made with reference to table 3.
TABLE 3
In this application, it is noted from table 3 that a represents test pass (i.e., normal), B represents test alarm (i.e., to be optimized), and C represents test fail (i.e., abnormal).
In this embodiment, the comprehensive evaluation score is calculated based on the evaluation scores corresponding to the evaluation indexes, and the evaluation scores corresponding to the evaluation indexes may be multiplied by one another to obtain the comprehensive evaluation score.
For example, a test pass score of 1, a test alarm score of 0.8, and a test fail score of 0 may be set. The overall evaluation score was calculated as follows:
P＝P 1 ×P 2 ×…×P n (P i scoring a single term i =1,2, \ 8230;, n)
Wherein, P represents a comprehensive evaluation score; p n And (3) expressing the evaluation score corresponding to the nth evaluation index.
Further, in the present application, after the evaluation scores corresponding to the evaluation indexes are multiplied to obtain the comprehensive evaluation score, the following scheme may be further implemented:
and if the comprehensive evaluation score is 1, judging that the vehicle speed limiting system passes the test.
And if the comprehensive evaluation score is greater than 0 point and less than 1 point, judging that the vehicle speed limiting system is to be optimized.
And if the comprehensive evaluation score is 0, judging that the vehicle speed limit system test does not pass.
According to the method and the device, the vehicle speed limiting system is tested from the perspective of each evaluation index, the corresponding evaluation score is determined, finally, each evaluation score is integrated to obtain the comprehensive evaluation score, and the passing level of the vehicle speed limiting system is integrally tested according to the comprehensive evaluation score, so that the performance of the vehicle speed limiting system can be efficiently, objectively and accurately tested.
In order to provide those skilled in the art with a better understanding of the present application, one embodiment of the present application will be described in its entirety with reference to fig. 3.
Referring to fig. 3, a general flowchart of a testing method of a vehicle speed limiting system according to an embodiment of the present application is shown. The method specifically comprises the following steps:
and 301, constructing a test evaluation index of the vehicle speed limiting system.
And step 302, outputting a simulation test result based on the simulation data corresponding to the speed limiting scene, and calculating a comprehensive evaluation score P.
In step 304, the test fails and the system logic needs to be reconstructed.
And 305, outputting a comprehensive evaluation score P after the test is passed.
At step 308, the system needs to be completed.
In summary, simulation data for simulating a speed-limiting scene is input into a vehicle speed-limiting system, the vehicle speed-limiting system is triggered to generate a control instruction sent to a test vehicle, feedback data of the test vehicle for executing the control instruction is obtained, and finally, the trafficability level of the vehicle speed-limiting system in various speed-limiting scenes is tested through at least one evaluation index.
