For example, the simulation test method of the autopilot algorithm provided by the embodiment of the present application may be applied to the architecture schematic diagram of a simulation console system shown in fig. 1. Fig. 1 is a schematic diagram of an architecture of a first simulation console system according to an embodiment of the present disclosure, so as to solve the above technical problem. As shown in fig. 1, the simulation console system may include: a front-end User Interface (UI) layer, a data layer, a service layer and an application layer.

The front-end UI layer is used for receiving a simulation resource acquisition request sent by terminal equipment of a target user, wherein the simulation resource acquisition request comprises an identifier of the target user and an identifier of a target automatic driving algorithm; and the simulation test system is also used for sending a simulation test instruction to the vehicle simulation system according to the target simulation resource and the identification of the target automatic driving algorithm.

The front end UI layer may include Hypertext Markup Language (HTML), Cascading Style Sheets (CSS), React, and corresponding files. The front-end UI layer processes page logic through the React, requests a scheduling data layer and a service layer through a hypertext Transfer Protocol (HTTP), and indirectly schedules an application layer.

It should be noted that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

Fig. 5 is a schematic flowchart of a first embodiment of a simulation test method of an autopilot algorithm according to an embodiment of the present application. The simulation test method of the automatic driving algorithm is applied to a simulation console system, and as shown in fig. 5, the simulation test method of the automatic driving algorithm may include the following steps:

s501, receiving a simulation resource obtaining request sent by terminal equipment of a target user.

In the embodiment of the application, a communication connection is pre-established between the terminal device of the user and the simulation console system, and the user can access the simulation console system through a browser of the terminal device, so that information interaction between the terminal device and the simulation console system can be realized through the communication connection.

For example, the terminal device may be a mobile phone, a computer, a tablet computer, or other terminal devices, and the specific type of the terminal device is not limited in the embodiments of the present application.

Wherein, the target user is a developer with simulation test requirements.

The simulation resource obtaining request comprises an identification of a target user and an identification of a target automatic driving algorithm. The identifier of the target user may be generated when the target user performs user registration in the simulation console system in advance. The identifier of the target user may be a user name of the target user, a telephone number of the target user, an identity card number of the target user, and the like, which is not specifically limited in the embodiment of the present application.

The simulation resources are test resources required for performing simulation test on the automatic driving algorithm. The simulation resources may include simulation test cases written by each user for each automatic driving algorithm in advance, and optionally, the simulation resources may further include simulation files, simulation environments, server resources, and the like. It should be understood that the content included in the simulation resource is not limited in the embodiments of the present application.

S502, according to the identification of the target user and the mapping relation, the target user role corresponding to the identification of the target user is obtained.

The mapping relationship is used for representing the corresponding relationship between the user identification and the user role.

The user roles are used for representing the roles of the user in the simulation console system, and different user roles correspond to different simulation resources. Optionally, different user roles may also have different permissions, such as data permissions, interface permissions, and menu permissions.

Exemplarily, fig. 6 is a schematic diagram of a mapping relationship provided in the embodiment of the present application. As shown in FIG. 6, user 1, user 2, and user 3 correspond to user role 1; user 3 corresponds to user role 1 and user role 2. The user role 1 corresponds to a menu authority 1, an interface authority 2 and a data authority 2, and the user role 2 corresponds to the menu authority 1, the menu authority 2, the interface authority 1, the interface authority 2, the interface authority 3, the data authority 1, the data authority 2 and the data authority 3.

The data authority is used for managing the simulation resources, and different data authorities can call different simulation resources.

Illustratively, the user role can be employee, management, manager, etc.; the simulation system can also be a simulation 1 part, a simulation 2 part and a simulation 3 part; the system can also be a simulation testing part, an algorithm writing part, a system management part and the like, and the embodiment of the application does not limit the specific names and actual contents of the user roles.

It should be understood that the mapping relationship may be stored in the database of the simulation console system in advance by a technician corresponding to the simulation console system, or may be obtained from a database external to the simulation console system in advance, and this is not particularly limited in this embodiment of the application.

For example, the mapping relationship can be represented by table 1.

TABLE 1

Taking the mapping relationship shown in table 1 as an example, if the identifier of the target user is the identifier 1 of the user, the target user roles corresponding to the identifiers of the target user can be determined as the user role 1 and the user role 2 according to the mapping relationship.

Before S501, a simulation test case sent by a user may also be received, and the simulation test case is associated with a user role corresponding to the user.

S503, determining the target simulation resource corresponding to the identification of the target automatic driving algorithm from the simulation resources corresponding to the target user role.

The simulation resources corresponding to the target user roles comprise a plurality of simulation test cases which are respectively written by a plurality of users according to a plurality of automatic driving algorithms in advance, and each user can write at least one simulation test case.

That is to say, the target simulation resource determined from the simulation resource corresponding to the target user role may be obtained by the target user through pre-editing with respect to the target automatic driving algorithm, or may be obtained by other users through pre-editing with respect to the target automatic driving algorithm.

In a possible implementation manner, according to the data authority corresponding to the role of the target user, the corresponding simulation resource under the data authority is obtained, so that the target simulation resource is determined from the simulation resources.

The target simulation resource may include a plurality of simulation resources, or may also include one simulation resource, and the number of simulation resources included in the target simulation resource is not limited in the embodiment of the present application.

S504, according to the target simulation resource and the identification of the target automatic driving algorithm, a simulation test instruction is sent to the vehicle simulation system.

The vehicle simulation system is used for carrying out simulation test on a target automatic driving algorithm through the target simulation resource according to the simulation test instruction.

After acquiring the target simulation resource, the simulation console system can interact with the terminal device of the user, so that the user can send a simulation test instruction to the simulation console system through the terminal device according to the received target simulation resource. For the simulation console system, after receiving the simulation test instruction, the simulation test instruction is forwarded to the vehicle simulation system.

The specific implementation manner and implementation principle of this step may refer to the embodiment shown in fig. 7, and are not described herein again.

According to the simulation test method of the automatic driving algorithm, a simulation control console system receives a simulation resource obtaining request sent by a terminal device of a target user, the simulation resource obtaining request comprises an identification of the target user and an identification of the target automatic driving algorithm, a target user role corresponding to the identification of the target user is obtained according to the identification of the target user and a mapping relation, a target simulation resource corresponding to the identification of the target automatic driving algorithm is determined from the simulation resources corresponding to the target user role, and a simulation test instruction is sent to a vehicle simulation system according to the target simulation resource and the identification of the target automatic driving algorithm. In the scheme, the target simulation resource is obtained according to the identification of the target user and the mapping relation, and the target simulation resource can be a simulation test case compiled by other users in advance, so that the user independent compiling process is omitted, the labor cost and the simulation resource cost are saved, the complexity of the simulation test is simplified, and the simulation test efficiency, the server resource utilization rate and the system safety are improved.

And the second message queue middleware is used for storing simulation test results.

In the embodiment, the simulation console system interacts with the simulation test result of the vehicle simulation system through the second message queue middleware, so that the robustness and the usability of the system are improved. Meanwhile, the simulation console system sends the simulation test result to the terminal equipment of the target user after acquiring the simulation test result, so that the target user can timely perform the next processing according to the simulation test result.

Optionally, when the test result indicates that the simulation resource used for executing the simulation test instruction has a problem, the user may modify the simulation resource according to the test result, so as to send the modified simulation test instruction to the simulation console system, so that the simulation console system forwards the modified simulation test instruction to the vehicle simulation system.

Optionally, in some embodiments, the timer may start timing, and after a preset duration of the timer is reached, the resources of the first message queue middleware and the resources of the second message queue middleware are released.

For example, the preset time period may be 6 hours, 12 hours, or 1 day, 2 days, 3 days, and the like, and may be determined according to the actual data size, which is not specifically limited in this embodiment of the present application.

In the embodiment of the application, the resource of the first message queue middleware and the resource of the second message queue middleware are released through the timeout device, so that the problem of data backlog of the first message queue middleware and the second message queue middleware can be solved, and the problem that the simulation resource acquisition request cannot be processed in time due to the data backlog is avoided.
