With the development of intelligent networked automobiles, more and more automobile parts (vehicle-mounted application modules) need to use cloud data. Taking map data as an example, in addition to the map data required by a navigation system controller in the conventional sense for planning a travel path, an autopilot controller is also required to be mapped for autopilot route recognition, and a life service carrier (e.g., a copilot screen, a headrest screen) based on geographical location information is also required to be mapped for displaying information. In order to ensure the accuracy and real-time performance of the map, the existing high-definition map data needs to have huge storage space, and the map data is often online data with a cloud end and is called and downloaded for use when needed.
When the map data is used by each part, the data is directly downloaded from the cloud end through the Internet of vehicles port. Therefore, when map data is called, bandwidth resources are wasted due to repeated downloading of different parts. In addition, in a situation where information security is becoming more severe, if not considered, great potential safety hazards are brought to some application scenarios, for example, tampered map data will affect automatic driving, and traffic accidents may be caused. If each part independently realizes information security, the development cost and complexity of the whole vehicle are greatly improved.

Detailed Description
The invention is described in detail below with reference to the figures and specific embodiments. The present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.
The embodiment provides a cloud data downloading method, which is applied to a cloud data downloading system, wherein the cloud data downloading system is deployed in a vehicle control system.
As shown in fig. 1, the cloud data downloading system includes a cloud server 3, and a plurality of vehicle-mounted application modules 1 and a network terminal 2 that are disposed on a vehicle. The network terminal 2 is a proxy server, and may be implemented by an individual ap (access point) hardware device, or by software of an MCU in a vehicle control system. The network terminal 2 specifically includes a processing unit 21, a cloud connection unit 22, and a plurality of application connection units 23. Each application connection unit 23 is connected with one vehicle-mounted application module 1 in a data line or wireless mode; the cloud connection unit 22 is configured to wirelessly connect to the cloud server 3.
The cloud connection unit 22 wirelessly connects to the cloud server 3 through a conventional remote security protocol to ensure the security of cloud data transmission. In this embodiment, the https client is adopted by the cloud connection unit 22 after the vehicle external information security is comprehensively considered; the application connection unit 23 is connected to the vehicle-mounted application module 1 in a data line manner by using an http server or an FTP client which has a low security level but a low cost and is convenient to connect.
The specific flow of the downloading method is shown in fig. 2:
after receiving data request information of a vehicle-mounted application module 1, the network terminal 2 calls the requested cloud data from the cloud server 3 for temporary storage, and then sends the temporarily stored cloud data to the vehicle-mounted application module 1, and the vehicle-mounted application module 1 serves as a main application module. Meanwhile, the network terminal 2 selects the vehicle-mounted application module 1 having a matching relationship with the main application module from the other vehicle-mounted application modules 1 through a preset application module matching state table to serve as a secondary application module, and then sends the temporarily stored cloud data to the secondary application module.
Each vehicle-mounted application module 1 has its own application module cooperation state table, the application module cooperation state tables are all stored in the network terminal 2, each application module cooperation state table has the cooperation state of the vehicle-mounted application module 1 and other application modules, and the cooperation state includes: with and without coordination.
In this embodiment, the following description is specifically given by taking downloading navigation map information as an example:
the vehicle-mounted application module 1 is a part 1, a part 2, a part 3 to a part n respectively.
1. The component 1 sends data request information to the network terminal 2 to apply for navigation map information;
after receiving the message, the http server notifies the https client to download data from the cloud server 3 through the processing unit 21;
after receiving the data, the https client notifies the processing unit 21, and the processing unit 21 transmits the data to the component 1 through the http server;
4. the processing unit 21 receives the data request notification sent by the component 1, and at the same time, determines whether the component 1 needs to be matched with other components (according to the application module matching state table), and selects the component 2;
5. when the processing unit 21 transmits data to the component 1, the data is synchronously transmitted to the component 2 through the http server corresponding to the component 2.
The application module coordination state table of the component 1 is as follows:
| part ID | XX1 | XX2 | XX3 | XXn |
| Mating state | 0 | 1 | 0 | 0 |
Where 0 indicates not needed and 1 indicates needed. During actual design, the application module matching state table can only output a list needing matching.
The above typical application scenario is that the component 1 is an automatic driving controller, and the component 2 is an in-vehicle display device. The automatic driving controller applies a high-precision map to the cloud for automatic driving path planning and synchronously displays the high-precision map to the in-vehicle user on the display device.
