Example 1
Fig. 1 is a schematic flowchart of a method for generating an autopilot high-value scenario use case according to an embodiment of the present disclosure.
Referring to fig. 1, in embodiment 1, a method for generating a use case of an autopilot high-value scene is provided, where the method includes the following steps:
s101, obtaining scene characteristic parameters, and constructing a scene use case base according to the scene characteristic parameters;
in particular implementations, the scene characteristic parameters include, but are not limited to, factors on which the driving environment depends and the range supported by the script commands, such as maps, vehicles, group relationships, and other elements. And constructing a scene use case base according to the scene characteristic parameters, including but not limited to inputting the acquired scene characteristic parameters into the existing scene use case base and obtaining a new scene use case base so that the new scene use case base is used for running an automatic driving algorithm.

Other elements include, but are not limited to, non-motor vehicles, pedestrians, obstacles, and the like. And constructing the scene use case base by adopting a conventional use case base construction mode according to the scene characteristic parameters. The scenario case library comprises a plurality of scenario cases. When the method is used, basic scenes are configured according to the existing scene construction scripts (including 5 types of simulation, control, constraint, tracking and perception) and matching with different characteristic maps, and scene use cases are generated on the basis of the basic scenes according to different scene algorithms and the driving design of the automatic driving controlled vehicle. For example, on the basis, the initial parameters, the operating parameters, the constraint objects, the trigger conditions and other elements of the basic scene vehicle and the automatic driving controlled vehicle are adjusted to generate a large-scale scene case according to the test matrix model.
It should be understood that the specific references listed above are for illustrative purposes only and should not be construed as limiting the application in any way.
S103, operating the scene use case base by using an automatic driving algorithm to obtain an actual weight ratio of the scene characteristic parameters, wherein the weight ratio is the ratio of the scene characteristic parameter weight which is successfully operated to the scene characteristic parameter weight which is failed to operate;
in specific implementation, the method for obtaining the actual weight ratio of the scene characteristic parameters by running the scene case library with an automatic driving algorithm includes, but is not limited to, executing the automatic driving algorithm in the scene case library to obtain the scene case library with failed execution; obtaining the execution failure weight of the scene characteristic parameters by using the example library of the scene with the execution failure through a logistic regression model; and obtaining the actual weight ratio of the scene characteristic parameters according to the execution failure weight.
For example, when the automatic driving algorithm is executed, if multiple scene characteristic parameters in multiple scene use cases cannot be successfully executed in the scene use case library, the scenes which cannot pass through are marked, and then the total number of the scene use cases which are failed to be executed due to the scene characteristic parameters is counted, so that the weight of the execution failure of each scene characteristic parameter is counted. Taking the slope in the scene characteristic as an example, when the system runs to the scene constructed by the slope and cannot pass through the scene constructed by the slope during the execution of the automatic driving algorithm, counting the total number of all scene cases which cannot be successfully executed due to the slope in the scene case library, and thus obtaining the execution failure weight of the slope, which is the scene characteristic parameter. Of course, each scene case contains a plurality of scene features, and each scene case also contains a plurality of scene features of execution failure, and the statistical manner is the same as that.

The method for constructing the prediction model includes, but is not limited to, combining a logistic regression model with probability through fitting a decision boundary and establishing the decision boundary, and then constructing the prediction model by using a sigmoid function.
For example, the example is continued with the scene feature gradient in S103, and in the scene case library constructed using the scene feature of the gradient, it is predicted how many scene cases that have failed to be executed after the execution of the constructed scene case library, and then it is predicted how many cases that have failed to be executed due to the gradient. Thereby obtaining the prediction failure weight of the scene characteristic parameter of gradient.
It should be understood that the specific references listed above are for illustrative purposes only and should not be construed as limiting the application in any way.
S107, constructing a feature evaluation model according to the actual weight ratio and the predicted weight ratio;
in the specific embodiment, a logistic regression model is used for classification, the simulated vehicle running result simulated according to the automatic driving algorithm is compared with the expected result of the scene use case base, and the comparison result is labeled. The label can be understood as a pre-prepared feature, such as failure or success, only the weight is calculated, such as the weight of the failure, the weight of the scene feature is obtained through a logistic regression model, and a feature evaluation model is established.
It should be understood that the specific references listed above are for illustrative purposes only and should not be construed as limiting the application in any way.

For example, continuing to use the scene feature of the slope in S103 as an example, in the scene case library constructed by the slope, the slope in the successfully executed scene case is subjected to parameter adjustment, and is adjusted in the direction of execution failure, so that the high-value scene case is obtained.
Further, adjusting the scene characteristic parameters to obtain a new scene use case base;
in specific implementations, the manner of adjusting the scene characteristic parameters includes, but is not limited to, inputting new scene characteristic parameters after manually adjusting the scene characteristic parameters, or inputting new scene characteristic parameters after selecting the characteristic parameters.
And repeating the steps on the new scene use case library to obtain a new high-value scene use case again.
In this embodiment, for a scenario where execution fails, for example, when the automatic driving algorithm fails, for example, a vehicle collision occurs, an expected event is not generated, and the like, the automatic driving algorithm performs scenario training again after repairing a related problem. The system can repeat the iterative scene training process periodically, can find the sample characteristics of the high-quality test samples, and can dynamically and continuously produce the high-quality test samples. And predicting whether the new generation case is a high-value case or not according to the execution result serving as a feedback continuous optimization characteristic weight coefficient, so that the purpose of generating a high-quality case capable of challenging the cloud automatic driving algorithm by continuously optimizing and improving the generation mode of the case is achieved.
Further, the adjusting the scene characteristic parameter to obtain a new scene use case further includes: and comparing the actual weight ratio with the predicted weight ratio to obtain the accuracy evaluation of the feature evaluation model.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Language Description Language), traffic, pl (core unified Programming Language), HDCal, JHDL (Java Hardware Description Language), langue, Lola, HDL, laspam, hardsradware (Hardware Description Language), vhjhd (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
