Based on the vehicle networking communication device, various embodiments of the vehicle networking communication method are provided.
As shown in fig. 4, fig. 4 is a car networking communication method applied to a car networking communication device including an interface component and a 5G communication component, which is provided by an embodiment of the present application, and includes, but is not limited to, the following steps:
in step S110, vehicle travel information is acquired through the interface component.
In one embodiment, the vehicle driving information includes, but is not limited to, vehicle state information generated by in-vehicle sensors, controllers, actuators, and the like, and road information transmitted from an internet-of-vehicles server or captured by a camera device provided in the vehicle. In one embodiment, before the vehicle driving information is acquired, the vehicle networking communication device needs to be initialized, including but not limited to: the vehicle-mounted sensor, the controller and the actuator are connected to the control processor through a CAN bus of the OBD interface part, the control processor calls a background processing program to analyze the user input parameters according to the received user input parameters, converts the user input parameters to generate an AT command, decomposes and packages the data into an IP data packet, and then stores the IP data packet in a memory and enables the IP data packet to correspond to the AT command, so that the matching speed of the data in the using process CAN be effectively accelerated.
In an embodiment, after the vehicle driving information is acquired, if data interaction with the internet of vehicles is required, the V2X communication component and the 5G communication component analyze that an AT command is received from the control processor, call a related internal function, perform network setting and establish network connection, respectively call IP data packets stored in the temporary storage memory according to designation of the AT command, and prepare for data transmission.
In step S120, the vehicle travel information is processed and mapped into first data conforming to the V2X communication protocol.
In one embodiment, data related to the internet of vehicles needs to meet the V2X communication protocol, therefore, vehicle driving information is processed and mapped into first data conforming to the V2X communication protocol before the data are sent, and not only can the reliability of data transmission be ensured, but also different types of data can be avoided from occupying 5G communication components at the same time by setting the priority of the V2X communication protocol data, so that the timeliness of the internet of vehicles communication is ensured.
And S130, when the flow of the first data exceeds a preset flow threshold, the first data is sent to the Internet of vehicles through the 5G communication component.
In an embodiment, because the data throughput capacity of the V2X communication component is limited, if the data volume is large, the characteristic of low delay of V2X is erased due to the occupied resources, and the fast low delay communication required by the internet of vehicles cannot be satisfied, therefore, in this embodiment, a preset traffic threshold needs to be set to determine the data throughput, and data interaction using the V2X communication component is avoided when the data volume is too large. The preset traffic threshold may be a data amount that needs to be sent in a unit time, or may be set by using other criteria, and may be used for determining the traffic of the first data, which is not limited in this embodiment.
In an embodiment, the communication device of the internet of vehicles further comprises a communication component of V2X of the internet of vehicles, and when the flow value of the first data does not exceed the preset flow threshold value, the communication component of V2X is used to transmit the first data to the roadside equipment and/or the internet of vehicles.
In an embodiment, when the first data is sent, a mode of only using the 5G communication component to interact with the internet of vehicles may be adopted, in this mode, it is not necessary to determine the traffic threshold, but the 5G communication component consumes a large amount of resources, the V2X communication component can save network resources relatively when meeting the low latency, and may also directly interact with the roadside device without forwarding the data through the control processor, so when the data throughput is not large, the efficiency of using the V2X communication component to interact with the internet of vehicles is high, which does not limit the embodiment.
As shown in fig. 5, fig. 5 is a car networking communication method applied to a car networking communication device including an interface component and a 5G communication component, according to an embodiment of the present application, where the car networking method includes, but is not limited to, the following steps:
step S210, receiving the traffic information sent by the Internet of vehicles through the V2X communication component and the 5G communication component;
in an embodiment, after the communication device for the internet of vehicles is started, the V2X communication component and the 5G communication component may keep a standby state to receive information at any time, or only the V2X communication component may be started to receive data, and the 5G communication component may be started to receive data when the data size is large, but this method needs to temporarily start the 5G communication component, and cannot meet the timeliness of the communication for the internet of vehicles, so in this embodiment, the 5G communication component and the V2X communication component are started at the same time to ensure the timeliness of data interaction.
Step S220, when the flow of the traffic information exceeds a preset flow threshold, the traffic information received by the 5G communication component is analyzed to obtain a first execution parameter.
In an embodiment, when the V2X communication component and the 5G communication component can simultaneously receive data, the enabled component can be determined by presetting a flow threshold, the instantaneity of traffic information is high, for example, when the data is used for navigation, a certain requirement is required for the transmission speed of the data, and the data volume is large, if only the V2X communication component is used for communication, resource occupation may be caused, and timeliness is affected, so when the flow exceeds the preset flow threshold, the 5G communication component is used for receiving the traffic information, and the V2X communication component is only used for information interaction with roadside devices or vehicles, which is beneficial to realizing low-delay vehicle networking applications.
In an embodiment, the data receiving of the communication component is started, the communication component may be enabled to receive data, or two communication components may be used to receive traffic information at the same time, and a channel of the USB expansion component is selected according to a judgment of a preset flow threshold, for example, when the data volume exceeds the flow threshold, the traffic information received by the 5G communication component is analyzed, and the same data in the V2X communication component is discarded, so that the data transmission rate can be further improved.
And step S230, sending the first execution parameter to the vehicle control unit through the interface component, so that the vehicle control unit controls the vehicle according to the first execution parameter.
In one embodiment, after receiving the traffic information, the control processor receives the traffic information through the USB serial port interface, analyzes the received data and parameters, regenerates a data packet and an AT command, analyzes the data and the AT command through the OBD interface part, sends a first execution parameter to a corresponding vehicle controller, and controls a vehicle actuator to make a corresponding action.
