Referring to fig. 3, the control system of the vehicle-mounted screen of the present application is composed of a primary driving screen, a secondary driving screen, a cloud platform, a message pushing platform and a service provider platform, wherein the primary driving screen and the secondary driving screen do not have direct communication, but realize information interaction through the cloud back stage and the message pushing platform.
The control system can realize functions of secondary driving screen authentication, vehicle-to-machine switch state synchronization, primary and secondary screen interaction and the like.
1. Auxiliary screen authentication
Vehicle authentication is understood to mean the assurance that only authorized vehicles or owners are able to use a particular vehicle function or service by means of authentication and verification. It is a verification process that is performed to ensure the safety, compliance and trustworthiness of an automotive system, with the aim of ensuring that only authorized users or vehicles can use specific vehicle functions or services, and protecting the safety and legitimacy of the vehicle system.
In the prior art, as the vehicle controls the main screen and the auxiliary screen simultaneously through the vehicle-mounted electronic control unit ECU, the main screen and the auxiliary screen of the vehicle can realize the synchronization of authentication information through the ECU. In the special architecture applied in the application, as no direct communication exists between the main driving screen and the auxiliary driving screen, an authentication method based on the auxiliary driving screen is provided, and the realization of an auxiliary driving screen authentication mechanism under the system architecture is ensured.
Specifically, referring to fig. 4, the secondary screen may first obtain the VIN number of the vehicle, and then take the device number and the VIN number of the secondary screen to authenticate in the background, and the background stores the mapping table of the VIN and the device number, so as to verify the validity of the device, and return a verification result.
2. On-off state synchronization of vehicle
It can be understood that, because the main driving screen and the auxiliary driving screen are directly not directly communicated under the applied framework, the user switch state on the main driving screen in the prior art cannot be transmitted to the auxiliary driving screen in real time, and the situation that information is not synchronous exists between the main driving screen and the auxiliary driving screen.
Specifically, referring to fig. 5, after the secondary driving screen is started, firstly, a request for acquiring a switch state of sensitive data is actively sent to the cloud platform, after the cloud platform receives the request, the switch state of the sensitive data is sent to the secondary driving screen, and the secondary driving screen receives the switch state of the sensitive data to perform a next operation according to the switch state, for example, when the switch state of the sensitive data is on, the next access action is allowed; when the sensitive data switch state is off, then the next access action is not allowed.
a) When a main driving user operates a sensitive data switch state on a main driving screen (HU), the sensitive data switch state can be reported to a cloud background in real time in the driving process.
b) After the POI application is started, the background switch state information can be actively acquired, and the driver is ensured to use the system on the premise of not affecting the safety.
c) When the switch state of the main driving screen is changed, the switch state is uploaded to the background again.
d) After receiving the sensitive data switch state of the main screen, the cloud background synchronizes the sensitive data switch state to the message pushing platform, and long connection is established between the message pushing platform and the auxiliary screen, so that the sensitive data switch state can be synchronized in real time.
The message pushing platform is cloud-to-cloud message pushing service, and can efficiently and rapidly transmit messages to equipment or users, so that real-time notification and message interaction are realized. When the background receives a new switch state, the background synchronizes to the secondary driving screen in real time through the message pushing platform, and high-efficiency application use under the permission condition is ensured.
A long connection is a connection over which a plurality of data packets can be transmitted, and during the connection hold period, both sides are required to transmit a link detection packet when no data packet is transmitted. In short, a long connection is a connection that can be maintained for a long time after the connection between the two parties is established, and data is continuously transmitted without newly establishing the connection before each data transmission. The channel before the switch state synchronization can be multiplexed every time, the connection is re-established without changing the switch state every time, and the resource and time for establishing the connection and releasing the connection every time of the short connection are saved.
e) When a user operates the secondary driving screen and needs to use corresponding sensitive data, if the sensitive data switch state is off at the moment, the next access operation is not allowed; if the switch state of the sensitive data is on at this time, the next access operation is allowed.
3. Main and auxiliary screen interaction method
Referring to fig. 6, in this embodiment, taking an application scenario of point of interest navigation as an example, an interaction process between a primary screen and a secondary screen is described:
1) The auxiliary screen user inputs the interest point information;
2) After receiving the interest point information input by the user, the secondary driving screen generates the interest point information to the cloud background;
3) The cloud background requests corresponding data of the interest point, such as position information of the interest point and the like, from a third-party navigation server according to the interest point information;
4) The third-party navigation service provider responds to the cloud platform request and returns a search result to the cloud back stage, wherein the search result can comprise information such as an interest point name, a position, a distance and the like;
5) The cloud background transmits the search result to the secondary driving screen for the user to check;
6) After the user checks the content of the search result of the secondary driving screen, performing operations such as confirmation and the like, sending secondary driving screen equipment information and selected interest point information to a cloud background by the secondary driving screen recording operation, and identifying interest point selection of the user;
7) After the cloud background receives the information in the step 6), positioning the corresponding main driving screen according to the auxiliary driving screen equipment information, and returning the interest point star system to the main driving screen through the MQTT protocol;
MQTT is a client-server based message publish/subscribe transport protocol. The MQTT communication is established between the background and the vehicle machine, the message of the secondary driving screen is synchronized to the background, and the background can send the message to the vehicle machine in real time; the car machine can upload some user preferences and some settings to the background, and the secondary driving screen acquires the information from the background and can recommend positions to the user according to the preferences.
8) The main driving screen receives the interest point prompt and displays related information, and allows a driver to operate the main driving screen and select to navigate to the destination.
9) The driver operates a main driving screen that displays navigation information to the destination.
It can be appreciated that the intelligent cabin design and the auxiliary screen technology are organically combined, so that a driver can quickly acquire interest point information from POI application of the auxiliary screen and share the interest point information to the main screen in the driving process through an auxiliary driver, and intelligent navigation is performed, and driving safety and driving convenience are improved.
The auxiliary driving screen is used as a selected auxiliary driving screen, so that the modification amount of host software is minimum in order to increase flexibility and freedom, a scheme which is not limited by the limitation of Ethernet or CAN communication in the vehicle is provided under the condition of lowest cost, and the original interfaces CAN be reused, so that development difficulty and development cost CAN be reduced to the minimum while rich services are provided.
