[0037] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] For easier understanding, please refer to Figure 1 , an embodiment of the present application provides a dynamic connection system between a remote driving cockpit and a racing car, comprising:

[0039] Racing car, used to access the remote driving cloud platform through the MQTT protocol and report racing car information to the remote driving cloud platform in real time. The racing car information includes location information and status information;

[0040] The remote driving cockpit is used to access the remote driving cloud platform through the HTTPS protocol. After the user logs in and authenticates, a websocket connection is established with the remote driving cloud platform. The available racing venues, cars, and car information are obtained from the remote driving cloud platform. A racing venue is selected from the available racing venues. An available car is selected according to the status information of the car in the racing venue and a connection request is sent.

[0041] The remote driving cloud platform establishes connections with multiple public cloud resource routing nodes through a remote communication protocol. After receiving a car connection request, it generates a node list based on the location information of the racing car and the remote driving cockpit and the network status of each public cloud resource routing node, and sends the node list to the remote driving cockpit.

[0042] The remote driving cockpit is also used to randomly generate a connection password string, connect to the public cloud resource routing nodes one by one according to the node order in the node list, until the connection is successful, and report the successfully connected target public cloud resource routing node and the connection password string to the remote driving cloud platform;

[0043] The remote driving cloud platform is also used to send the target public cloud resource routing node and connection password string to the racing car selected by the remote driving cockpit, so that the racing car establishes a connection with the target public cloud resource routing node through the connection password string, and transmits audio and video streams and sensor data streams to the remote driving cockpit through the network channel established by the target public cloud resource routing node, and receives vehicle control commands sent by the remote driving cockpit.

[0044] In the embodiment of the present application, a large number of racing cars can be connected to the Internet Internet of Things access layer through the Internet of Things protocol (MQTT protocol) based on certificate encryption, and then connected to the remote driving cloud platform. After successfully accessing the remote driving cloud platform, the racing car information is reported to the remote driving cloud platform in real time. The racing car information includes location information and status information. The status information includes whether the racing car can be selected and whether there is a fault. For example, if the status information of the racing car is fault-free and can be selected, it means that the current racing car has no fault and can be selected for remote control of the racing car. The remote driving cloud platform is responsible for recording and updating the racing car information in real time to the memory database.

[0045] The remote driving cockpit is connected to the remote driving cloud platform through the HTTPS protocol. When the user enters the remote driving cockpit to log in and authenticate, the remote driving cockpit establishes a websocket connection with the remote driving cloud platform to obtain available racing venues, cars, and car information from the remote driving cloud platform in real time, and selects a racing venue from the available racing venues through the websocket connection. After entering the selected racing venue, an available car (that is, a car in the selected state) is selected according to the status information of the car in the racing venue and a car connection request is sent to the remote driving cloud platform.

[0046] Furthermore, the remote driving cloud platform is also used to check the status information of the selected racing car after receiving the car connection request. If the selected racing car is in a selectable state (i.e., an idle state), the racing car is set from the selectable state to the selected state; if the selected racing car is in a selected state or a faulty state, the selection failure is returned, prompting the user to reselect the racing car.

[0047] The remote driving cloud platform maintains contact with multiple public cloud resource routing nodes through a remote communication protocol, and evaluates the network status of each public cloud resource routing node in real time. Specifically, the remote driving cloud platform obtains the load, number of connections, bandwidth and / or delay information of each public cloud resource routing node in real time to determine the network status of each public cloud resource routing node.

[0048] After receiving the car connection request, the remote driving cloud platform allocates available public cloud resource routing nodes according to the location information of the racing car and the remote driving cockpit and the network status of each public cloud resource routing node; sorts the available public cloud resource routing nodes according to the network status of each available public cloud resource routing node, generates a node list, and sends the node list to the remote driving cockpit. Among them, the first k public cloud resource routing nodes that are closest to the remote driving cockpit and the racing car, have the lowest delay, the fewest connections, and / or the highest bandwidth can be selected as available public cloud resource routing nodes, and the available public cloud resource routing nodes can be sorted according to delay or bandwidth to generate a node list.

[0049] The remote driving cockpit is also used to randomly generate a connection password string, and connect to the public cloud resource routing nodes one by one according to the node order in the received node list until a public cloud resource routing node is successfully connected and a secure connection channel is established. The successful connection target public cloud resource routing node and the connection password string are then reported to the remote driving cloud platform through the websocket interface.

[0050] The remote driving cloud platform sends the target public cloud resource routing node and connection password string to the selected racing car through the Internet Internet of Things access layer. The racing car also establishes a secure connection channel with the target public cloud resource routing node through these parameters.

[0051] The remote driving cockpit and racing car can obtain the virtual network allocated by the target public cloud resource routing node. Through this virtual network, the vehicle control instructions from the remote driving cockpit to the racing car can be transmitted with low latency on a secure connection channel. The audio and video streams and sensor data streams can also be transmitted from the racing car to the remote driving cockpit, thus realizing remote racing.

[0052] Furthermore, when the user ends the remote racing, the remote driving cockpit sends a request to end the car control to the remote driving cloud platform; after receiving the request to end the car control, the remote driving cloud platform sends a public cloud resource release instruction to the car selected by the remote driving cockpit, so that the car releases the target public cloud resource routing node connection, restores the car to a selectable state, and returns an end of car control response; after receiving the end of car control response, the remote driving cockpit releases the target public cloud resource routing node connection. The resources of the remote driving cockpit and the car in this application realize resource pool sharing, and can dynamically establish and release control relationships on demand.

[0053] This application uses existing Internet and Internet of Things technologies to achieve access management of massive racing cars and access management of massive remote driving cockpits, and establishes remote control and audio-visual tactile feedback connections between cockpits and racing cars according to user needs, overcomes the limitations of existing technologies and achieves large-scale regional coverage and resource sharing, improves resource utilization and efficiency of remote racing cars, realizes dynamic connections between massive remote driving cockpits and massive racing cars, and improves the safety of racing cars; and, this application optimizes data transmission paths through public cloud resources across the country, reduces the number of intermediate nodes, and can effectively reduce network latency, thereby improving user experience; makes full use of secure connection methods such as HTTPS and MQTT, and realizes key security guarantees such as user identity authentication and secure data transmission through user password authentication, certificates and other methods, providing security guarantees for exchanging key parameters of public cloud routing resources on these channels; utilizes the capacity redundancy of public cloud resources, as well as intelligent routing and real-time monitoring of network status to ensure stable transmission of data in various network environments; and with the advantage of the wide distribution of public cloud resources, achieves large-scale regional coverage, enables large-scale remote racing to be widely promoted, and improves resource utilization.

[0054] The above is an embodiment of a system for dynamically connecting a remote driving cockpit and a racing car provided by the present application. The following is an embodiment of a method for dynamically connecting a remote driving cockpit and a racing car provided by the present application.

[0055] The embodiment of the present application provides a method for dynamically connecting a remote driving cockpit and a racing car, comprising:

[0056] Step 110, the remote driving cloud platform establishes a connection with the racing car through the MQTT protocol, and receives racing car information reported by the racing car in real time, wherein the racing car information includes location information and status information.

[0057] A large number of racing cars can be connected to the Internet IoT access layer through the IoT protocol (MQTT protocol) based on certificate encryption, and then connected to the remote driving cloud platform. After successfully connecting to the remote driving cloud platform, the racing car information is reported to the remote driving cloud platform in real time. The racing car information includes location information and status information. The status information includes whether the racing car can be selected and whether there is a fault. For example, if the racing car status information is fault-free and can be selected, it means that the current racing car has no fault and can be selected for remote control. The remote driving cloud platform is responsible for recording and updating the racing car information in real time to the memory database.

[0058] Step 120, the remote driving cloud platform establishes a connection with the remote driving cockpit through the HTTPS protocol, establishes a websocket connection with the remote driving cockpit after the user logs in and authenticates the identity, sends the available racing venues, cars and car information to the remote driving cockpit, and the remote driving cockpit selects a racing venue from the available racing venues, selects an available car according to the status information of the car in the racing venue, and sends a car connection request.

[0059] The remote driving cockpit is connected to the remote driving cloud platform through the HTTPS protocol. When the user enters the remote driving cockpit to log in and authenticate, the remote driving cockpit establishes a websocket connection with the remote driving cloud platform. The remote driving cloud platform sends the available racing venues, cars and car information to the remote driving cockpit in real time through the websocket connection, so that the remote driving cockpit selects a racing venue from the available racing venues. After entering the selected racing venue, it selects an available car (that is, a car in the selected state) according to the status information of the car in the racing venue and sends a car connection request to the remote driving cloud platform.

[0060] Step 130: After receiving the vehicle connection request, the remote driving cloud platform generates a node list according to the location information of the racing car and the remote driving cockpit and the network status of each public cloud resource routing node, and sends the node list to the remote driving cockpit, so that the remote driving cockpit connects to the public cloud resource routing nodes one by one according to the node sequence in the node list until the connection is successful, and reports the successfully connected target public cloud resource routing node and the randomly generated connection password string; wherein, the remote driving cloud platform establishes connections with multiple public cloud resource routing nodes through the remote communication protocol.

[0061] After receiving the car connection request, the remote driving cloud platform checks the status information of the selected car. If the selected car is in the selected state or fault state, it returns the selection failure and prompts the user to reselect the car. If the selected car is in the selectable state, the car is set from the selectable state to the selected state.

[0062] The remote driving cloud platform maintains contact with multiple public cloud resource routing nodes through a remote communication protocol, and evaluates the network status of each public cloud resource routing node in real time. Specifically, the remote driving cloud platform obtains the load, number of connections, bandwidth and / or delay information of each public cloud resource routing node in real time to determine the network status of each public cloud resource routing node.

[0063] After receiving the car connection request and setting the car from the selectable state to the selected state, the remote driving cloud platform allocates available public cloud resource routing nodes according to the location information of the car and the remote driving cockpit and the network status of each public cloud resource routing node; sorts the available public cloud resource routing nodes according to the network status of each available public cloud resource routing node, generates a node list, and sends the node list to the remote driving cockpit. Among them, the first k public cloud resource routing nodes that are closest to the remote driving cockpit and the car, have the smallest delay, the fewest connections, and / or the highest bandwidth can be selected as available public cloud resource routing nodes, and the available public cloud resource routing nodes can be sorted according to delay or bandwidth to generate a node list.

[0064] After receiving the node list, the remote driving cockpit randomly generates a connection password string and connects to the public cloud resource routing nodes one by one according to the node order in the received node list until a public cloud resource routing node is successfully connected and a secure connection channel is established. Then, the successfully connected target public cloud resource routing node and the connection password string are reported to the remote driving cloud platform through the websocket interface.

[0065] Step 140: The remote driving cloud platform sends the target public cloud resource routing node and the connection password string to the racing car selected by the remote driving cockpit, so that the racing car establishes a connection with the target public cloud resource routing node through the connection password string, and transmits the audio and video stream and the sensor data stream to the remote driving cockpit through the network channel established by the target public cloud resource routing node, and receives the vehicle control command sent by the remote driving cockpit.

[0066] The remote driving cloud platform sends the target public cloud resource routing node and connection password string to the selected racing car through the Internet Internet of Things access layer. The racing car also establishes a secure connection channel with the target public cloud resource routing node through these parameters.

[0067] The remote driving cockpit and racing car can obtain the virtual network allocated by the target public cloud resource routing node. Through this virtual network, the vehicle control instructions from the remote driving cockpit to the racing car can be transmitted with low latency on a secure connection channel. The audio and video streams and sensor data streams can also be transmitted from the racing car to the remote driving cockpit, thus realizing remote racing.

[0068] Furthermore, the process also includes step 150, in which the remote driving cloud platform receives a request to end vehicle control sent by the remote driving cockpit, sends a public cloud resource release instruction to the racing car selected by the remote driving cockpit, so that the racing car releases the target public cloud resource routing node connection, restores the racing car to a selectable state, and returns a response to end vehicle control to the remote driving cockpit, so that the remote driving cockpit releases the target public cloud resource routing node connection.

[0069] When the user ends the remote racing, the remote driving cockpit sends a request to end the car control to the remote driving cloud platform; after receiving the request to end the car control, the remote driving cloud platform sends a public cloud resource release instruction to the car selected by the remote driving cockpit, so that the car releases the target public cloud resource routing node connection, restores the car to a selectable state, and returns an end of car control response; after receiving the end of car control response, the remote driving cockpit releases the target public cloud resource routing node connection. The resources of the remote driving cockpit and the car in this application realize resource pool sharing, and can dynamically establish and release control relationships on demand. For details, please refer to Figure 2 The timing diagram of the dynamic connection between the remote driving cockpit and the racing car is shown.
