DETAILED DESCRIPTION

[0017] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0018] refer to Figure 1 and Figure 2In a first aspect of the present invention, a method for integrating multiple services of Ivehicle based on the AAOS system is provided, including: S100. Registering a callback service to the AAOS system through the hardware abstraction layer of the vehicle side, and monitoring the publishing status of the newly released service through the callback service; S200. Judging whether the newly released service belongs to the Ivehicle service according to the publishing status of the service; S300. Obtaining a service instance of the newly released service judged to be the Ivehicle service, and saving the service instance to the routing table mapping structure.

[0019] In step S100 of some embodiments of the present invention, the hardware abstraction layer of the vehicle side registers the callback service with the AAOS system, including: during the startup of the AOS system, registering the callback service with the AAOS system through the hardware abstraction layer of the vehicle side.

[0020] Specifically, during the AAOS startup process, the Vehicle HAL program on the vehicle side first registers an IServiceCallback through the ServiceManager. When the ServiceManager detects that a new HIDL service has been released, it will call back the IServiceCallback and notify the Interface and Instance names of the service.

[0021] It should be noted that Android Automotive OS, as an in-vehicle operating system, needs to be interconnected with other subsystems in the vehicle. Android Automotive OS defines a standard hardware abstraction layer HAL (HardwareAbstraction Layer) to standardize the calling interface of each subsystem and Framework, and provides a standard programming interface for upper-level applications through CarService and related Car API. VehicleHAL stands for vehicle hardware abstraction layer. Its function is to define a standard interface so that CarService can ignore the specific implementation of each car manufacturer. In other words, CarService calls the interface defined by VehicleHAL, and manufacturers are responsible for implementing these interfaces.

[0022] In step S200 of some embodiments of the present invention, judging whether the newly released service belongs to the Ivehicle service according to the release status of the service includes: judging whether the newly released service belongs to the Ivehicle service according to the instance name and interface name of the newly released service.

[0023] Specifically, the Vehicle HAL program can determine whether it is an IVehicle type service by the service's Interface name. In the onRegistration callback function, the instance name and interface name published by the new IVehicle service are obtained, and the interface name is used to determine whether it is an IVehicle type service.

[0024] It should be noted that Vendor Interface Object is the abbreviation of Vendor Interface Object. The partitions it defines are reasonably planned as follows: Product: OEM-related customization, mainly including Apps, SDK, product sysprops, etc.; System: Android system Framework and Daemons; Treble Interface: Treble interface; Vendor: hardware-related drivers / Daemons. ODM: ODM-related customization, including ODM-related Apps, SDK, etc., and VINTF support Further, the determination of whether the newly released service belongs to the Ivehicle service includes: if the instance name or interface name is Ivehicle, then determining that the newly released service belongs to the Ivehicle service. Specifically, if it is determined to be an IVehicle type service, then using the getService function of IVehicle to obtain the service instance and record it in the routing table map structure.

[0025] In step S300 of some embodiments of the present invention, obtaining a service instance of a newly released service determined to be an Ivehicle service and saving the service instance in a routing table mapping structure includes: obtaining one or more service instances of the newly released service through a getService function in the Ivehicle service, and recording all service instances in the routing table mapping structure.

[0026] Furthermore, the routing table mapping structure is used to distribute the function request from the vehicle property service. The routing table map structure stores all IVehicle type service instances and is used to distribute the function request from CarPropertyService.

[0027] refer to Figure 2In a specific embodiment of the present invention, the method for integrating multiple services based on IVehicle of the AAOS system includes: in the VehicleHAL program of the vehicle, registering an IserviceCallback through the ServiceManager to monitor the new IVehicle service publishing status; obtaining the instance name and interface name of the new IVehicle service publishing in the onRegistration callback function, and judging whether it belongs to the IVehicle type service according to the interface name. If the service is an IVehicle type service, the getService function of IVehicle is used to obtain the service instance and record it in the routing table map structure.

[0028] Example 2 refer to Figure 3 According to a second aspect of the present invention, an IVehicle multi-service integration system 1 based on the AAOS system is provided, comprising: a monitoring module 11, used to register a callback service to the AAOS system through the hardware abstraction layer of the vehicle side, and monitor the publishing status of the newly released service through the callback service; a judgment module 12, used to judge whether the newly released service belongs to the Ivehicle service according to the publishing status of the service; a saving module 13, used to obtain a service instance of the newly released service judged to be the Ivehicle service, and save the service instance to the routing table mapping structure.

[0029] Furthermore, the monitoring module 11 includes: a registration unit, which is used to register a callback service in the AAOS system through the hardware abstraction layer of the vehicle terminal; and a monitoring unit, which is used to monitor the publishing status of the newly published service through the callback service.
