These accompanying drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed Description of Specific Embodiments

[0071] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0072] The modules in this application refer to functional modules or logical modules. They can be in software form and achieve their functions by a processor executing program code, or in hardware form. "And / or" describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, both A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0073] First, the nouns involved in this application are explained:

[0074] gRPC communication protocol: It is a high-performance, open-source, and general RPC (Remote Procedure Call) framework that enables the client and the server to make remote calls as if they were calling local methods, without having to worry about the underlying communication details.

[0075] With the improvement of the intelligent level of automobiles, traditional MCU chips can no longer meet the requirements of the throughput capacity of a large amount of heterogeneous data and faster data processing capacity in in-vehicle systems. Therefore, SoC chips with higher data transmission efficiency and greater computing power have become the inevitable choice for the main control chips of in-vehicle systems.

[0076] To further improve the performance of in-vehicle systems, a dual-SoC can be deployed. In the prior art, generally, only one WiFi is directly connected to one of the SoCs in an in-vehicle system, so that the requirement for the SoC to access the Internet through WiFi can be realized. However, how to support the other SoC to access the Internet through WiFi has become an urgent problem to be solved.

[0077] The technical solutions of this application are illustrated below with specific embodiments. These several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0078] The embodiments of this application provide an Internet access method. The execution subject of this method is the first system-level chip of the in-vehicle system. Figure 1 It is a schematic structural diagram of the in-vehicle system provided by the embodiments of this application. As Figure 1 shown, the in-vehicle system 100 includes a first system-level chip 10, a second system-level chip 20, a switch 30, and a WiFi chip 40. Both the first system-level chip 10 and the second system-level chip 20 are connected to the switch 30 through cables, and the first system-level chip 10 and the second system-level chip 20 can communicate with each other through the switch 30. The WiFi chip 40 is directly connected to the first system-level chip 10 to provide WiFi function support for the first system-level chip 10. Therefore, the first system-level chip 10 can communicate with the cloud through the WiFi network.

[0079] Figure 2A schematic flowchart of the Internet access method provided by the embodiment of the present application. The execution subject of this method is the first system-level chip of the in-vehicle system. As Figure 2 shown, the Internet access method provided by this embodiment may include:

[0080] S201. Receive downlink WiFi data; the downlink WiFi data includes a destination address;

[0081] S202. If the destination address corresponds to the second system-level chip, send the downlink WiFi data to the switch so that the switch forwards the downlink WiFi data to the second system-level chip.

[0082] In a specific implementation, the first system-level chip can communicate with the cloud, while the second system-level chip cannot directly communicate with the cloud. Therefore, the first system-level chip can receive the second downlink WiFi data sent by the cloud and forward the second downlink WiFi data to the second system-level chip, thereby realizing the indirect communication between the second system-level chip and the cloud, where the destination address of the second downlink WiFi data corresponds to the second system-level chip. Specifically, a forwarding rule can be set in the first system-level chip in advance. When the first system-level chip receives the downlink WiFi data, it obtains the destination address of the downlink WiFi data. If the destination address corresponds to the second system-level chip, it sends the downlink WiFi data to the switch, and the switch will forward the received downlink WiFi data to the second system-level chip. Thus, the second system-level chip can receive the downlink WiFi data sent by the cloud and access the Internet through WiFi.

[0083] In this embodiment, after the first system-level chip receives the downlink WiFi data, it identifies whether the destination address of the downlink WiFi data corresponds to the second system-level chip, and when the destination address of the downlink WiFi data corresponds to the second system-level chip, it sends the downlink WiFi data to the second system-level chip through the switch. Therefore, in the case where the second system-level chip cannot directly access the Internet through WiFi, the second system-level chip can utilize the WiFi communication function of the first system-level chip to receive the data sent by the cloud through the WiFi network. Thus, in the case where there is only one WiFi chip in the in-vehicle system, it can support dual SoCs to access the Internet through WiFi, improve the system performance, and without the need to additionally increase the WiFi chip, effectively reducing the cost.

[0084] In a possible implementation manner, the method further includes:

[0085] If the destination address corresponds to the first system-level chip, send the downlink WiFi data to the first target application of the first system-level chip.

[0086] In a specific implementation, the downlink WiFi data received by the first system-on-chip includes first downlink WiFi data and second downlink WiFi data. The destination address of the first downlink WiFi data corresponds to the first system-on-chip, and the destination address of the second downlink WiFi data corresponds to the second system-on-chip. Therefore, when the first system-on-chip recognizes that the destination address of the received downlink WiFi data corresponds to the first system-on-chip, it sends the downlink WiFi data to the first target application of the first system-on-chip.

[0087] In this embodiment, after the first system-on-chip receives the downlink WiFi data, it recognizes the destination address of the downlink WiFi data. When the destination address of the downlink WiFi data corresponds to the first system-on-chip, it directly forwards the downlink WiFi data to the first target application inside the chip to achieve WiFi Internet access.

[0088] In a possible implementation manner, the method further includes:

[0089] Obtain the current network status, where the network status includes the WiFi connection status and the data traffic enabled status;

[0090] Send the current network status to the second system-on-chip so that the second system-on-chip performs corresponding network configurations according to the current network status.

[0091] Figure 3 This is a schematic diagram of the application scenario provided by the embodiments of the present application. As Figure 3 shown, the first system-on-chip can send the current network status to the second system-on-chip through communication methods such as gRPC. When the current WiFi connection status of the first system-on-chip is connected, the second system-on-chip performs the configurations required for WiFi communication, so that the second system-on-chip can perform WiFi Internet access; when the current data traffic enabled status of the first system-on-chip is enabled, the second system-on-chip performs the configurations required for traffic communication, so that the second system-on-chip can perform traffic Internet access, realizing the synchronization of the network status of the first system-on-chip and the second system-on-chip.

[0092] Exemplarily, the first system-on-chip may further include a fifth virtual network card. The fifth virtual network card is connected to the switch and is used to communicate with the second system-on-chip. Sending the current network status to the second system-on-chip may include sending the current network status to the switch through the fifth virtual network card, so that the switch forwards the current network status of the first system-on-chip to the second system-on-chip.

[0093] As Figure 3As shown in the figure, the first system-on-chip includes at least one network card, which can be, for example, the first network card eth0. The first network card eth0 is connected to a switch. To achieve service isolation, the first network card eth0 can be virtualized to obtain the first virtual network card eth0.1. The first system-on-chip uses the first virtual network card eth0.1 to receive or send WiFi data for WiFi communication. Similarly, the first network card eth0 can also be virtualized to obtain the fifth virtual network card, and the fifth virtual network card is used to communicate with the second system-on-chip.

[0094] In a possible implementation, receiving downlink WiFi data includes:

[0095] Receiving downlink WiFi data through the first virtual network card;

[0096] Sending downlink WiFi data to the switch includes:

[0097] Sending downlink WiFi data to the switch through the first virtual network card.

[0098] In a specific implementation, the forwarding rule of the first virtual network card can be preset. When the first virtual network card receives downlink WiFi data, it identifies and analyzes the destination address of the downlink WiFi data. When the destination address of the downlink WiFi data corresponds to the first system-on-chip, the downlink WiFi data is forwarded to the first target application of the first system-on-chip; when the destination address of the downlink WiFi data corresponds to the second system-on-chip, the downlink WiFi data is sent to the switch, and the downlink WiFi data is forwarded to the second system-on-chip through the switch.

[0099] The above embodiments illustrate how to implement the downlink WiFi communication of the second system-on-chip. Next, how to implement the uplink WiFi communication of the second system-on-chip will be described. In a possible implementation, the method further includes:

[0100] Receiving the second uplink WiFi data sent by the second system-on-chip through the switch, and sending the second uplink WiFi data to the cloud through the WiFi network.

[0101] In a specific implementation, when the second system-on-chip needs to send the second uplink WiFi data to the cloud, it can first send the second uplink WiFi data to the first system-on-chip through the switch, and the first system-on-chip sends the received second uplink WiFi data to the cloud, thereby implementing the uplink WiFi communication of the second system-on-chip. Therefore, in the case where it cannot directly communicate with the WiFi network, the second system-on-chip can utilize the WiFi function of the first system-on-chip to achieve WiFi Internet access.

[0102] Exemplarily, sending the second uplink WiFi data to the cloud via the WiFi network includes:

[0103] Sending the second uplink WiFi data to the remote communication module via the switch, so that the remote communication module sends the second uplink WiFi data to the cloud;

[0104] Or, sending the second uplink WiFi data to the WiFi hotspot, so that the WiFi hotspot sends the second uplink WiFi data to the cloud.

[0105] In a specific implementation, as Figure 3 shown, the in-vehicle system may further include a remote communication module or a WiFi hotspot; wherein, the remote communication module is connected to the switch, and the first system-level chip and the second system-level chip can access the Internet through the remote communication module. A WiFi chip may be provided in the remote communication module. At this time, taking the uplink WiFi communication as an example, the uplink WiFi communication path of the first system-level chip is: the first virtual network card eth0.1 - switch - remote communication module - cloud. The WiFi chip may also be independent of the remote communication module. At this time, the first system-level chip further includes a wireless network card wlan0, and the in-vehicle system further includes a WiFi hotspot. Taking the uplink WiFi communication as an example, the uplink WiFi communication path of the first system-level chip is: the first virtual network card eth0.1 - wlan0 - WiFi hotspot - cloud.

[0106] Exemplarily, the remote communication module may be a Tbox (Telematics Box).

[0107] In a possible implementation manner, the method further includes:

[0108] Receiving the first downlink traffic data through the second virtual network card.

[0109] As Figure 3 shown, the second virtual network card eth0.2 can also be virtualized from the first network card eth0. The second virtual network card eth0.2 is connected to the switch. The second virtual network card eth0.2 can receive the first downlink traffic data sent by the cloud and can also send the first uplink traffic data to the cloud, thereby supporting the first system-level chip to access the Internet through traffic. Among them, taking the uplink traffic communication as an example, the uplink traffic communication path of the first system-level chip is: the second virtual network card eth0.2 - switch - remote communication module - cloud.

[0110] In a possible implementation manner, the method further includes:

[0111] If the current WiFi connection status is connected, configure the WiFi default gateway of the first system-level chip as the address of the first virtual network card, and configure routing forwarding and address translation;

[0112] If the current data traffic enabled status is enabled, configure the data traffic default gateway of the first system-level chip as the address of the remote communication module.

[0113] As Figure 3 shown, an EcarxConnectivityService can be set in the first system-level chip. The EcarxConnectivityService in the first system-level chip obtains the current network status of the first system-level chip, synchronizes the current network status of the first system-level chip to the second system-level chip, and performs corresponding network configurations according to the current network status of the first system-level chip. Among them, the EcarxConnectivityService can obtain the WiFi connection status of the first system-level chip from the WiFi framework (WiFi FMK) of the first system-level chip, and obtain the data traffic enabled status of the first system-level chip through the data traffic setting management application Setting APP. An EcarxConnectivityService can also be correspondingly set in the second system-level chip. The EcarxConnectivityService in the second system-level chip obtains the current network status of the first system-level chip and performs corresponding network configurations according to the current network status of the first system-level chip.

[0114] Figure 4 It is a schematic flowchart of the network configuration of the first system-level chip provided by the embodiment of the present application. As Figure 4 shown, if the current WiFi connection status is connected, configure the WiFi default gateway of the first system-level chip as the address of the first virtual network card, and configure routing forwarding and address translation; if the current data traffic enabled status is enabled, configure the data traffic default gateway of the first system-level chip as the address of the remote communication module; if the current WiFi connection status is disconnected, clear the routing forwarding and address translation configurations, and clear the WiFi default gateway configuration; if the current data traffic enabled status is disabled, clear the data traffic default gateway configuration.

[0115] Exemplarily, the method further includes:

[0116] If the current WiFi connection status is connected and the data traffic enabled status is enabled, receive downlink WiFi data through the first virtual network card.

[0117] In a specific implementation, the priority of setting up WiFi Internet access is higher than that of mobile data Internet access. Therefore, when the current WiFi connection status is connected and the mobile data connection status is enabled, the first system-on-chip receives downlink WiFi data through the first virtual network card and / or sends uplink WiFi data.

[0118] The embodiment of the present application also provides another Internet access method, and the execution subject of this method is Figure 1 the second system-on-chip shown. This method includes:

[0119] Receiving the second downlink WiFi data sent by the first system-on-chip through the switch, and forwarding the second downlink WiFi data to the second target application of the second system-on-chip; the destination address of the second downlink WiFi data corresponds to the second system-on-chip.

[0120] In a specific implementation, the first system-on-chip can communicate with the cloud, while the second system-on-chip cannot directly communicate with the cloud. Therefore, the cloud sends the second downlink WiFi data with the destination address corresponding to the second system-on-chip to the first system-on-chip, and the second system-on-chip receives the second downlink WiFi data sent by the first system-on-chip through the switch, thereby realizing the indirect communication between the second system-on-chip and the cloud and accessing the Internet through WiFi.

[0121] In a possible implementation manner, the method further includes:

[0122] Obtaining the current network status of the first system-on-chip, where the network status includes the WiFi connection status and the mobile data connection status;

[0123] Performing corresponding network configuration according to the current network status of the first system-on-chip.

[0124] In a specific implementation, the first system-on-chip can send the current network status to the second system-on-chip through communication methods such as gRPC. When the current WiFi connection status of the first system-on-chip is connected, the second system-on-chip performs the configuration required for WiFi communication, so that the second system-on-chip can access the Internet through WiFi; when the current mobile data connection status of the first system-on-chip is enabled, the second system-on-chip performs the configuration required for mobile data communication, so that the second system-on-chip can access the Internet through mobile data, realizing the synchronization of the network status of the first system-on-chip and the second system-on-chip.

[0125] As Figure 3 shown, the first system-on-chip includes a first virtual network card, and the first virtual network card is connected to the switch. The first virtual network card is used to receive downlink WiFi data. Exemplarily, performing corresponding network configuration according to the current network status of the first system-on-chip includes:

[0126] If the WiFi connection status of the current first system-on-chip is connected, configure the WiFi default gateway of the second system-on-chip as the address of the first virtual network card;

[0127] If the data traffic enabling status of the current first system-on-chip is enabled, configure the data traffic default gateway of the second system-on-chip as the address of the remote communication module.

[0128] Exemplarily, the second system-on-chip may further include a sixth virtual network card. The sixth virtual network card is connected to the switch and is used for communicating with the first system-on-chip; obtaining the current network status of the first system-on-chip may include receiving, through the sixth virtual network card, the current network status of the first system-on-chip forwarded by the switch.

[0129] In a possible implementation manner, receiving the second downlink WiFi data sent by the first system-on-chip through the switch includes:

[0130] Receiving the second downlink WiFi data through the third virtual network card;

[0131] The method further includes:

[0132] Receiving the downlink traffic data through the fourth virtual network card.

[0133] As Figure 3 shown, the second system-on-chip includes at least one network card. For example, it may be the second network card eth1. The second network card eth1 is connected to the switch. To achieve service isolation, the second network card eth1 can be virtualized to obtain the third virtual network card eth1.1 and the fourth virtual network card eth1.2. The second system-on-chip receives the second downlink WiFi data and / or sends the second uplink WiFi data through the third virtual network card eth1.1 to implement WiFi communication; the second system-on-chip receives the second downlink traffic data and / or sends the second uplink traffic data through the fourth virtual network card eth1.2 to implement traffic communication.

[0134] The above embodiments illustrate how to implement the downlink WiFi communication of the second system-on-chip. The following describes how to implement the uplink WiFi communication of the second system-on-chip. In a possible implementation manner, the method further includes:

[0135] Sending the second uplink WiFi data to the first system-on-chip through the switch, so that the first system-on-chip sends the second uplink WiFi data to the cloud.

[0136] In a specific implementation, when the second system-on-chip needs to send second uplink WiFi data to the cloud, it can first send the second uplink WiFi data to the first system-on-chip through a switch, and the first system-on-chip sends the received second uplink WiFi data to the cloud, so as to implement the uplink WiFi communication of the second system-on-chip. Therefore, in the case where it cannot directly communicate with the WiFi network, the second system-on-chip can use the WiFi function of the first system-on-chip to access the Internet via WiFi.

[0137] For the Internet access method provided by the embodiments of the present application, when the second system-on-chip needs to perform WiFi communication with the cloud, the cloud can send second downlink WiFi data corresponding to the target address of the second system-on-chip to the first system-on-chip, and the second system-on-chip receives the second downlink WiFi data sent by the first system-on-chip through the switch, so as to implement indirect communication between the second system-on-chip and the cloud and access the Internet via WiFi.

[0138] The embodiments of the present application provide another Internet access method, which is applied to Figure 1 the switch shown in the figure. The method includes:

[0139] Receiving second downlink WiFi data sent by the first system-on-chip and forwarding the second downlink WiFi data to the second system-on-chip; the destination address of the second downlink WiFi data corresponds to the second system-on-chip.

[0140] In a specific implementation, in the downlink WiFi communication of the second system-on-chip, the first system-on-chip receives second downlink WiFi data whose destination address corresponds to the second system-on-chip and sends the second downlink WiFi data to the switch. The switch forwards the received second downlink WiFi data to the second system-on-chip, so that the second system-on-chip can receive data sent by the cloud through the WiFi communication method.

[0141] In a possible implementation manner, the method further includes:

[0142] Receiving second uplink WiFi data sent by the second system-on-chip and forwarding the second uplink WiFi data to the first system-on-chip, so that the first system-on-chip sends the second uplink WiFi data to the cloud.

[0143] In a specific implementation, in the uplink WiFi communication of the second system-on-chip, the second system-on-chip sends the second uplink WiFi data to the switch, the switch forwards the received second uplink WiFi data to the first system-on-chip, and then the first system-on-chip sends the second uplink WiFi data to the cloud, so that the second system-on-chip can send data to the cloud through the WiFi communication method.

[0144] The Internet access method provided by the embodiment of the present application can realize two-way communication between the second system-on-chip and the cloud by forwarding the second downlink WiFi data and / or the second uplink WiFi data through a switch. Therefore, when there is only one WiFi chip in the in-vehicle system, it can support dual SoCs to access the Internet through WiFi, improve the system performance, and effectively reduce the cost without adding an extra WiFi chip.
