[0002] Currently, in the context of the rapid transformation of the automotive industry, in-vehicle intelligent cockpit technology, as one of the core areas of automotive intelligent development, is showing an explosive growth trend. The intelligent cockpit integrates advanced human-machine interaction systems, infotainment systems, and vehicle control functions, and its function richness is changing with each passing day, bringing an unprecedented driving experience to users. With the popularization of mobile Internet and the wide application of smart phones, car owners' demands for vehicle intelligent control are no longer limited to inside the vehicle. Realizing remote control and convenient operation of the intelligent cockpit through mobile phones has become the urgent expectation of more and more car owners. Such demands not only improve the convenience of vehicle use for users but also conform to the development trend of the Internet of Things era where everything is interconnected.

[0003] However, the increasing complexity of intelligent cockpit functions has brought huge challenges to the interaction between mobile phone applications (APPs) and intelligent cockpits. To effectively control various functions of the intelligent cockpit by the mobile phone APP, the development team needs to carry out a large amount of development docking work. This involves the adaptation of different system architectures, communication protocols, and data formats, and requires a large amount of human, material, and time costs. More critically, intelligent cockpit technology is in a stage of rapid development, and version iteration and upgrade are frequent. Each upgrade of the intelligent cockpit may bring new functions, performance optimization, and architecture adjustment. To ensure that the mobile phone APP can always maintain good compatibility and collaborative working ability with the latest version of the intelligent cockpit, the development team must keep up with the update pace of the intelligent cockpit and invest a considerable amount of development effort in the synchronous upgrade and optimization of the APP. This is undoubtedly a time-consuming and laborious task, which not only increases the development cost but also extends the product's market launch cycle, posing extremely high requirements on the enterprise's technology R & D capabilities and market response speed.

[0041] Please refer to Figure 1 , a schematic flowchart of a method for remotely controlling a vehicle provided by an embodiment of the present application, which may specifically include:

[0042] S110. When receiving an instruction transmission request from a mobile terminal, obtain a first communication status of the mobile terminal and a second communication status of a target vehicle;

[0043] Exemplarily, when the mobile terminal sends a request to the cloud to transmit a vehicle control instruction, such as inputting an instruction like "turn on the air conditioner for heating" through voice or text, the system will immediately start detecting the communication status between the mobile terminal and the target vehicle. For the mobile terminal, its first communication status is obtained, which includes but is not limited to the network type where the mobile terminal is located, such as Wi-Fi, 4G, 5G, etc., signal strength, network latency, bandwidth and other parameters. These parameters comprehensively reflect the current communication capabilities of the mobile terminal. For the target vehicle, its second communication status is obtained, which also covers the network conditions of the vehicle, such as the in-vehicle network connection status of the vehicle, whether it is connected to a specific hotspot, etc. and related communication performance indicators. This information will serve as the basic data for determining the instruction transmission path subsequently.

[0044] Comprehensively understanding the communication status of the mobile terminal and the target vehicle can provide an accurate basis for selecting a suitable instruction transmission path subsequently. Different communication statuses will affect the efficiency, stability and reliability of instruction transmission. By obtaining this information in real time, the system can make a better decision according to the actual situation, avoid instruction transmission failures or delays caused by communication problems, and thus improve the quality of the entire remote control process.

[0045] S120. Determine the instruction transmission path according to the first communication status and the second communication status, where the instruction transmission path is the transmission path of the vehicle control instruction input by the user based on the mobile terminal;

[0046] Exemplarily, after the cloud obtains the first communication status of the mobile terminal and the second communication status of the target vehicle, it will analyze and evaluate these two sets of communication status data according to preset rules. For example, if both the mobile terminal and the target vehicle have good communication conditions, such as both are connected to a high-speed and stable Wi-Fi network with high signal strength and low latency, a direct and efficient transmission path will be selected; if the communication condition of one party is poor while that of the other party is good, a transmission path that uses the party with better communication conditions for relaying or optimization will be adopted. In short, by comprehensively considering the communication status, a path that is most suitable for the current situation and can ensure that the vehicle control instruction input by the user on the mobile terminal can be successfully transmitted from the mobile terminal to the target vehicle is determined.

[0047] Dynamically determining the instruction transmission path according to the communication status can make full use of the existing communication resources of the mobile terminal and the target vehicle and adapt to different network environments and device states. This flexibility enables the system to find the best way for instruction transmission in various complex and changeable communication scenarios, improve the success rate and efficiency of instruction transmission, reduce the situation of untimely or failed control caused by communication environment differences, and enhance the user experience.

[0048] S130. Send the information data corresponding to the instruction transmission path to at least one of the mobile terminal and the target vehicle, so that the mobile terminal sends the vehicle control instruction to the target vehicle according to the instruction transmission path, or so that the target vehicle establishes a communication connection with the mobile terminal according to the instruction transmission path, so that the mobile terminal sends the vehicle control instruction to the target vehicle based on the communication connection.

[0049] Exemplarily, after determining the instruction transmission path, the cloud will send the information data related to this path, such as the specific selected path type, to the mobile terminal or the target vehicle, and may also send it to both at the same time. If the information data is sent to the mobile terminal, the mobile terminal will, based on this information, send the vehicle control instruction input by the user to the target vehicle according to the specified instruction transmission path. For example, if the path is to be relayed through a specific cloud server, the mobile terminal will send the vehicle control instruction to the cloud server according to the relevant information, and then the cloud server will forward the vehicle control instruction to the target vehicle. If the information data is sent to the target vehicle, the target vehicle will establish a communication connection with the mobile terminal according to this information. After the connection is established, the mobile terminal can send the vehicle control instruction to the target vehicle based on this connection.

[0050] Sending the instruction transmission path information data to the relevant devices ensures that both the mobile terminal and the target vehicle know how to perform instruction transmission or establish a communication connection. This makes the entire remote control process have clear guidance and reduces communication errors caused by inconsistent or unclear information between devices. Whether the instruction is actively sent by the mobile terminal or the instruction is received after the target vehicle establishes a connection, it can proceed smoothly under the clear path guidance, thereby improving the reliability and stability of the remote control.

[0051] In summary, the method for remotely controlling a vehicle proposed in the embodiment of the present application determines an instruction transmission path based on the first communication state and the second communication state, and sends the information data corresponding to the instruction transmission path to at least one of the mobile terminal and the target vehicle, so that the mobile terminal sends the vehicle control instruction to the target vehicle according to the instruction transmission path, or so that the target vehicle establishes a communication connection with the mobile terminal according to the instruction transmission path. It does not depend on the underlying communication protocol of a specific vehicle model and can intelligently adapt to various vehicle models and different versions of intelligent cockpits, improving the versatility, compatibility and collaborative working ability of the system.

[0052] In some examples, the determining the instruction transmission path according to the first communication state and the second communication state includes:

[0053] If the first communication state and the second communication state are the first target states, determine a first transmission path, where the first target states are communication states when the communication parameters are greater than or equal to a preset parameter threshold;

[0054] If at least one of the first communication state and the second communication state is a second target state, determine a second transmission path, where the second target state is a communication state when the communication parameter is less than the parameter threshold.

[0055] Exemplarily, when each communication parameter in the first communication state of the mobile terminal and the second communication state of the target vehicle, such as: latency, packet loss rate, jitter, bandwidth, response time, or bit error rate, etc., is greater than or equal to the preset parameter threshold, it is considered to be in the first target state. This means that at this time, the communication environments of both the mobile terminal and the target vehicle are relatively ideal, the network condition is good, and the conditions for efficiently and stably transmitting data are available. In this case, it is determined to adopt the first transmission path. The specific first transmission path is a relatively direct and efficient transmission method in the entire technical solution.

[0056] When each communication parameter in the first communication state of the mobile terminal and the second communication state of the target vehicle, such as: latency, packet loss rate, jitter, bandwidth, response time, bit error rate, etc., is less than the preset parameter threshold, it is considered to be in the second target state. This indicates that there are certain problems in the communication environment of at least one party. For example: the network condition is not good, there are problems such as high latency, packet loss, or insufficient bandwidth. In this case, problems will occur when directly performing conventional instruction transmission. For this situation, it is determined to adopt the second transmission path. The second transmission path is a method that is more suitable for ensuring instruction transmission when the communication condition is not good in the entire technical solution, so as to overcome the influence brought by poor communication parameters and ensure that the instruction can be successfully transmitted to the target vehicle.

[0057] By quantitatively judging the communication state, when the communication state is good, that is, in the first target state, adopting the first transmission path can make full use of the good network conditions to achieve fast and direct transmission of vehicle control instructions, so that the user's control instructions can be received and executed by the vehicle in a timely manner, greatly improving the real-time performance and user experience of remote control. For example, when the user wants to turn on the vehicle air conditioner, it can be quickly controlled in a good communication state without waiting for a long time.

[0058] When the communication state is poor, that is, when at least one party is in the second target state, switch to the second transmission path. This flexible path selection mechanism enables the system to adapt to various complex and changeable communication environments. Even when the communication parameters are not ideal, the system can ensure the transmission of instructions through a specific second transmission path, avoiding control failures caused by communication problems, and greatly enhancing the reliability and stability of the entire remote control vehicle system. For example, when the vehicle is in an underground parking lot with weak signals, or when the mobile terminal is in a remote area with unstable network, it is still possible to attempt to control the vehicle through the second transmission path. This way of dynamically selecting the transmission path according to the communication state can reasonably allocate system resources.

[0059] In some examples, the determining the first transmission path if the first communication state and the second communication state are the first target state includes:

[0060] If the first communication state and the second communication state are the first target state, determine whether the target vehicle and the mobile terminal are located in the same local area network;

[0061] If the target vehicle and the mobile terminal are located in the same local area network, the first transmission path is to transmit the vehicle control instruction through the communication channel between the target vehicle and the mobile terminal;

[0062] If the target vehicle and the mobile terminal are not located in the same local area network, the first transmission path is to receive the vehicle control instruction uploaded by the mobile terminal and forward the vehicle control instruction to the target vehicle.

[0063] Exemplarily, when it is detected that the mobile terminal and the target vehicle are in the same local area network, it means that their connection at the network level is relatively tight. A local area network usually has characteristics such as low latency, high bandwidth, and stable connection. For example, in a home environment, mobile terminals such as mobile phones and the target vehicle, assuming the vehicle supports home network connection, are both connected to the same wireless router, forming a local network environment. In this environment, data interaction can occur between the mobile terminal and the target vehicle based on the established communication channel. This direct communication method bypasses problems such as complex routing, long transmission distances, and network congestion in the wide area network, making data transmission more efficient and fast.

[0064] Based on the above advantages, the cloud server selects to directly transmit the vehicle control instruction between the two through the established communication channel as the first transmission path. This selection minimizes the latency and interference during the instruction transmission process, ensuring that vehicle control instructions issued by the user, such as unlocking the door and starting the engine, can be quickly and accurately received and executed by the target vehicle, thus providing an instant response user experience.

[0065] If the mobile terminal and the target vehicle are not on the same local area network. For example, the mobile terminal is in the user's office and connected to the office network, while the target vehicle is parked in an outdoor parking lot and connected to another network. In this case, it is necessary to use the cloud server as an intermediate bridge. The cloud server has a wide network coverage and powerful processing capabilities, and can receive data uploaded by the mobile terminal in different network environments and forward it to the target vehicle. The first transmission path at this time is: the mobile terminal first uploads the vehicle control instruction to the cloud server. This step establishes a connection with the cloud server through the network where the mobile terminal is located, such as the mobile data network or the office Wi-Fi, and sends out the instruction data. After receiving the instruction, the cloud server uses its own network configuration and intelligent routing function to forward the instruction to the target vehicle. Although this method of relaying through the cloud server adds some links compared to direct transmission within the local area network, it can effectively overcome the communication obstacles when the mobile terminal and the target vehicle are not on the same local area network, ensuring that the instruction can be accurately transmitted from the mobile terminal to the target vehicle and guaranteeing the normal operation of the remote control function.

[0066] This way of further subdividing the transmission path according to whether it is on the same local area network makes full use of the high efficiency of communication within the local area network and the flexibility of the cloud server as a relay. Direct communication within the same local area network can reduce the intermediate links of data transmission and reduce latency; while relaying through the cloud server when in different local area networks ensures that even if the vehicle and the mobile terminal are in different network environments, the instruction transmission can be achieved, expanding the applicable range of remote control.

[0067] In some examples, in the case where the target vehicle and the mobile terminal are not located on the same local area network, the sending the information data corresponding to the instruction transmission path to at least one of the mobile terminal and the target vehicle includes:

[0068] Sending the information data corresponding to the instruction transmission path to the mobile terminal, so that the mobile terminal sends the vehicle control instruction to the cloud according to the instruction transmission path corresponding to the information data, and the vehicle control instruction carries the vehicle identifier of the target vehicle, and the vehicle identifier is used to uniquely identify the target vehicle;

[0069] Receiving the vehicle control instruction, and determining the network address of the target vehicle according to the vehicle identifier;

[0070] Forwarding the vehicle control instruction to the target vehicle based on the network address.

[0071] Exemplarily, first, the information data corresponding to the instruction transmission path is sent to the mobile terminal. After receiving this information, the mobile terminal constructs and sends a vehicle control instruction to the cloud server according to the specified instruction transmission path. The vehicle control instruction carries a target vehicle identifier, such as a Vehicle Identification Number (VIN). The VIN is the unique identifier of the vehicle, similar to the vehicle's ID card number, and it is unique globally. By carrying the VIN in the vehicle control instruction, the mobile terminal clearly tells the cloud server the specific target vehicle that the instruction is aimed at, enabling the cloud server to accurately process the instruction subsequently.

[0072] After receiving the vehicle control instruction sent by the mobile terminal, the cloud server first extracts the target vehicle identifier (VIN) from the vehicle control instruction. Then, the cloud server uses its own stored database or related mapping mechanism to determine the current network address of the target vehicle based on this VIN. This database or mapping mechanism pre-stores the VINs of all registered vehicles and the corresponding network address information. By querying this database, the cloud server can quickly and accurately find the current network location of the target vehicle.

[0073] After determining the network address of the target vehicle, the cloud server forwards the received vehicle control instruction to the target vehicle based on this network address. In this process, the cloud server acts as an intelligent transfer hub to ensure that the vehicle control instruction can reach the target vehicle smoothly from the mobile terminal, regardless of how complex the network environment is between them. In this way, even if the mobile terminal and the target vehicle are not in the same local area network, reliable remote control instruction transmission can be achieved.

[0074] Determining the network address of the target vehicle through the vehicle identifier and forwarding the instruction ensures that the vehicle control instruction can reach the target vehicle accurately. Even in a complex network environment, remote communication between the mobile terminal and the target vehicle can be achieved in this way, improving the accuracy and reliability of remote control and avoiding mis-sending the vehicle control instruction to other vehicles.

[0075] In some examples, if at least one of the first communication state and the second communication state is the second target state, determining the second transmission path includes:

[0076] If at least one of the first communication state and the second communication state is the second target state, the second transmission path is to transmit the vehicle control instruction through the communication channel between the target vehicle and the mobile terminal.

[0077] Exemplarily, the first communication state of the mobile terminal and the second communication state of the target vehicle are continuously monitored, and the communication quality is evaluated by comparing various communication parameters, such as delay, packet loss rate, jitter, bandwidth, response time, bit error rate, etc., with preset parameter thresholds. When even only one of the two communication states satisfies the condition that the communication parameter is less than the preset parameter threshold, it is determined that the communication condition is relatively poor, and the system selects the second transmission path. This second transmission path is specified to directly use the communication channel between the target vehicle and the mobile terminal to transmit vehicle control instructions. This design skips some complex transfers or other judgment processes and directly establishes a communication link between the two for command transmission. This judgment mechanism is based on the basic need to ensure command transmission. Even in the case of an unsatisfactory communication environment, it is necessary to ensure that the vehicle control instructions can be transmitted to the target vehicle as much as possible.

[0078] In the case of poor communication conditions, the command transmission process is simplified. It avoids command transmission delays or failures caused by complex communication strategies, so that even when the communication status is not ideal, the vehicle control command still has a direct and effective transmission path, ensuring the basic availability of the remote control function and improving the adaptability of the system in different communication environments.

[0079] In some examples, the sending of information data corresponding to the instruction transmission path to at least one of the mobile terminal and the target vehicle includes:

[0080] If the communication state of one of the target vehicle and the mobile terminal is the second target state, the information data of the instruction transmission path is sent to the other one, so that the other one establishes a communication connection with the one according to the instruction transmission path corresponding to the information data.

[0081] Exemplarily, when the communication state is the second target state, the instruction transmission path information data is sent in the following manner: if the communication state of one of the target vehicle and the mobile terminal is in the second target state, that is, the communication state is poor, then the relevant information data of the instruction transmission path is sent to the other party. The party receiving the information data will establish a communication connection with the party in the second target state based on the instruction transmission path corresponding to these information data. The purpose of this is to ensure that when the communication state of one party is poor, communication can still be actively established through the other party to achieve the transmission of vehicle control instructions.

[0082] This method of sending information and establishing communication connections enhances the ability to cope with uneven communication conditions. By flexibly sending information to the party with better communication status and letting it actively establish a connection, the success rate of communication establishment can be increased, and the smooth transmission of instructions can be guaranteed, thereby improving the stability and reliability of remote control in complex communication environments.

[0083] In some examples, the other party establishes a communication connection with one of them according to the instruction transmission path corresponding to the information data, including:

[0084] The other party establishes a socket channel to one of them according to the instruction transmission path corresponding to the information data;

[0085] The other party sends the vehicle control instruction to one of them based on the socket channel.

[0086] Exemplarily, a socket is a network programming interface that plays a very important role in network communication. Its core function is to establish a reliable two-way communication link between different devices, such as a mobile terminal and a target vehicle. Two-way communication means that data can flow in both directions, which is crucial for the transmission of vehicle control instructions. For example, a mobile terminal can send vehicle control instructions, such as start, stop, unlock, etc., to the target vehicle through this link, and at the same time, the target vehicle can also feedback some information, such as the current state of the vehicle, the execution result of the instruction, etc., to the mobile terminal through this link. This reliable link ensures the accuracy and integrity of data during transmission, reducing the possibility of data loss or error.

[0087] The other party that receives the information data will establish a socket channel to one of those in the second target state according to the instruction transmission path corresponding to these information data. After the socket channel is established, the other party can send the vehicle control instruction to one of them based on this channel, thus completing the instruction transmission process. Using a socket channel to establish a communication connection provides a stable and reliable way for the transmission of vehicle control instructions. Socket technology has a mature mechanism in network communication, can adapt to different network environments and device states, and ensure the integrity and accuracy of data transmission. This not only improves the success rate of instruction transmission, but also further enhances the stability and robustness of the entire remote control system in complex communication scenarios, ensuring that the user's control instructions can be accurately conveyed to the target vehicle.

[0088] As Figure 2 shown, this application proposes a system for remotely controlling a vehicle, and the system includes: a data acquisition module 21, a data transmission module 22, and an instruction execution module 23;

[0089] The data acquisition module 21 is configured to: when receiving an instruction transmission request from a mobile terminal, acquire the first communication state of the mobile terminal and the second communication state of the target vehicle;

[0090] The data transmission module 22 is configured to determine an instruction transmission path according to the first communication state and the second communication state, where the instruction transmission path is the transmission path of the vehicle control instruction input by the user based on the mobile terminal.

[0091] The instruction execution module 23 is configured to send the information data corresponding to the instruction transmission path to at least one of the mobile terminal and the target vehicle, so that the mobile terminal sends the vehicle control instruction to the target vehicle according to the instruction transmission path, or so that the target vehicle establishes a communication connection with the mobile terminal according to the instruction transmission path, so that the mobile terminal sends the vehicle control instruction to the target vehicle based on the communication connection.

[0092] For the effects of the above system when applying the foregoing method, reference may be made to the description in the foregoing method embodiments, which will not be elaborated herein.
