In the embodiment of the specification, the data, the states and the executable actions of the vehicle-mounted sensors and the vehicle-mounted controllers are packaged in a class manner to generate a unified service interface, and the unified service interface layer provides services for the application layer, so that the functions or resources of all the vehicle-mounted sensors and the controllers are converted into services. When the application program is developed, only the class is required to be instantiated, so that the method has good compatibility, is beneficial to reducing the development difficulty of the vehicle-mounted application program, improves the development efficiency of the application program, and shortens the development period of the application program; when the application program runs, only a corresponding service interface is required to be called to send a control request, the details of the vehicle-mounted network and data interaction are shielded, the application program can concentrate on the logic function of the application program, and the reliability of vehicle service control is improved.
S403: the unified resource management layer sorts the control requests based on the time of receiving the control requests, and generates a control request queue.
In practical application, for the control request with earlier receiving time (corresponding to earlier time when the application program sends the control request to the unified resource management layer), the control request can be arranged at a position in front of the control request queue, namely, the subsequent unified resource management layer can process the control request with earlier arrangement, which is beneficial to the unified resource management layer to process the control request reasonably and orderly, and avoids the problem that the system performance is reduced due to confusion when a plurality of programs call the same service function at the same time.
As shown in fig. 5, in the embodiment of the present specification, the acquisition target control request may include:
s501: and the unified resource management layer acquires the control request queue.
S503: the unified resource management layer determines a first unprocessed control request which is arranged according to the control request receiving time sequence in the control request queue.
In the embodiment of the present specification, the first unprocessed control request is the control request (the control request with the earliest transmission time/reception time) that is the control request that is arranged at the forefront in the control request queue.
S505: the unified resource management layer takes the first unprocessed control request as the target control request.
The control request queue is acquired through the uniform resource management layer, and control requests in the control request queue are sequentially processed according to the time sequence, so that the data written first can be read by the uniform resource management layer first, and the execution sequence of the control requests sent by a plurality of application programs is guaranteed to be strictly carried out according to the time sequence. The method is beneficial to avoiding the problem that the system performance is reduced and the reliability of vehicle service control is improved due to confusion when a plurality of programs call the same service function at the same time.
S303: and the unified resource management layer determines the state information of the target service based on the control attribute information.
Specifically, the control attribute information of the target service may include an identification code of the target service, and the identification code may include, but is not limited to, a character string composed of at least one of letters, numbers, and special characters; different services can be distinguished by using the identification code; in this embodiment of the present disclosure, the unified resource management layer may acquire a function or an executable action of the vehicle-mounted controller, and generate state information of a target service, where the state information of the target service may include an identification code of the target service, a value of the target service, an identification code of an application program that currently locks the target service (which application program currently occupies the target service when needed later), a maximum locking time of the target service (how long the target service can be locked at most, and a time period for which the target application program needs to lock the target service is less than the maximum locking time of the target service), and a remaining release time of the target service calculated by using a timer. In practical application, the identification code of the target service included in the control attribute information of the target service may be used to determine the state information of the corresponding target service.
S305: and when the unified resource management layer determines that the state information of the target service comprises occupied state, extracting authority information of the target application program from the control attribute information.
Specifically, the target application includes an application corresponding to the target control request.
In this embodiment of the present disclosure, when the unified resource management layer determines that the remaining release time of the target service is not 0, it indicates that the target service is currently occupied, that is, the state information of the target service includes occupied, and the unified resource management layer extracts rights information of the target application from the control attribute information. In the embodiment of the present disclosure, the rights information of the target application is pre-generated by the unified resource management layer based on the rights acquisition request sent by the target application. In a specific embodiment, the authority information of the target application program may include an authority identification code of the target application program, and the authority identification code may include, but is not limited to, a character string composed of at least one of letters, numbers, and special characters, by which different application programs can be distinguished, and the authority identification code contains information capable of indicating the authority of the application program, for example, the authority information of the security function related application program may include an authority identification code with a highest bit of 1, and the authority information of the non-security function related application program may include an authority identification code with a highest bit of 0.
As shown in fig. 6, before the unified resource management layer obtains the target control request, the method may further include:
s601: and responding to the function starting instruction, and sending a permission acquisition request to the uniform resource management layer by the target application program.
Specifically, the permission acquisition request carries attribute information and an initial permission identifier of the target application program.

S603: and the unified resource management layer generates an application authority identification of the target application program based on the attribute information of the target application program, and sends the application authority identification to the target application program.
In this embodiment of the present disclosure, the unified resource management layer may analyze based on the attribute information of the target application program, determine that the target application program is an application program related to a security function or an application program related to a non-security function, and when the unified resource management layer determines that the target application program is an application program related to a security function, generate a permission identification code with a highest bit of 1 as an application permission identification of the target application program; when the unified resource management layer determines that the target application program is an application program related to the non-safety function, a permission identification code with the highest bit of 0 can be generated and used as the application permission identification of the target application program. In practice, the above-mentioned safety function-related applications may include, but are not limited to, applications involving door control and travel control (e.g., one-touch door opening, automatic emergency braking, etc.); applications related to non-secure functions described above may include, but are not limited to, applications related to in-vehicle entertainment systems (e.g., smoking mode, bluetooth comfort zone, etc.).
S605: and the target application program modifies the initial permission identifier into the application permission identifier, and takes the application permission identifier as permission information of the target application program.
In the embodiment of the specification, after receiving the application permission identifier sent by the unified resource management layer, the target application program can modify the initial permission identifier into the application permission identifier based on the application permission identifier, and uses the application permission identifier as the permission information of the target application program, so that the unified resource management layer can conveniently determine whether to preempt the service based on the related permission information when competition exists later. The unified resource management layer generates the application authority identification of the target application program based on the attribute information of the target application program, and the target application program takes the application authority identification as the authority information of the target application program, so that different authorities can be set according to the types (such as functional safety related or nonfunctional safety related) of the application program, potential safety hazards possibly generated when a plurality of application programs need to call the same service are avoided, the safety and reliability of vehicle service control are improved, and the vehicle service control is more orderly and reasonable.
S307: and the unified resource management layer determines authority information of the competing application program based on the control attribute information.
Accordingly, the authority information of the competing application may include an authority identification code of the competing application, and the authority identification code may include, but is not limited to, a character string composed of at least one of letters, numbers, and special characters, with which different applications can be distinguished, and the authority identification code contains information capable of indicating the authority of the application, for example, the authority information of the security function related application may include an authority identification code having a highest order of 1, and the authority information of the non-security function related application may include an authority identification code having a highest order of 0. The authority information of the contention application is also pre-generated by the unified resource management layer based on the authority acquisition request sent by the contention application, the generation manner is similar to S601-S605, and the specific process can refer to the related description of S601-S605, which is not repeated here.
S309: when the authority information of the target application program and the authority information of the competing application program meet the preset priority service condition, the unified resource management layer updates the state information of the target service based on the control attribute information and forwards the target control request to the corresponding controller so as to realize corresponding vehicle function control.
In a specific embodiment, the authority information of the target application program and the authority information of the competing application program meet the preset priority service condition may include: the highest bit of the authority identification code of the target application program is 1, and the highest bit of the authority identification code of the competing application program is 0 (i.e. the target application program is an application program related to a safety function, and the competing application program is an application program related to a non-safety function), at this time, a preset priority service condition is met (the target application program can be preferentially serviced), and the unified resource management layer can update the state information of the target service based on the control attribute information and forward the target control request to a corresponding controller to realize corresponding vehicle function control. Wherein, the unified resource management layer updates the state information of the target service based on the control attribute information may include, but is not limited to: updating the identification code of the application program currently locking the target service based on the identification code of the target application program, and updating the residual release time of the target service based on the time length of locking the target service by the target application program when the target application program needs to lock the target service. In practical applications, there are some target applications that do not need to lock the target service (e.g. only need to perform the action once), at this time, the target service may not be locked, i.e. the remaining release time of the target service is set to 0, and then the target service can be directly invoked if there are applications that need to invoke the service.
