[0026] With the continuous advancement of intelligent transportation and vehicle networking technologies, the position of automobile remote control and monitoring systems in the automotive industry is becoming increasingly important. In-vehicle T-Box is widely used in fields such as vehicle positioning, remote diagnosis and vehicle condition monitoring. However, the current in-vehicle T-Box system mainly relies on cellular networks such as 3G / 4G / 5G. However, cellular networks have certain limitations in terms of coverage and signal stability, especially in remote mountainous areas, oceans, deserts and other areas with weak communication infrastructure. Traditional cellular networks are difficult to ensure the continuity and stability of vehicle remote control.

[0027] In response to the above problems, the present application provides a vehicle remote control method, which is applied to a vehicle-mounted T-BOX, and the method includes: detecting the communication status of the cellular network on the vehicle-mounted T-BOX; if the cellular network is unavailable and the vehicle-mounted T-BOX has successfully located the communication signal of the satellite network, then receiving the remote control command of the vehicle's external terminal device based on the satellite communication network to achieve remote control of the vehicle. In the vehicle remote control scenario, this solution detects the available status of the cellular network and the satellite signal positioning status. When the cellular network is unavailable and the satellite signal has been successfully located, the satellite communication network is used to receive the remote control command, thereby helping to ensure the continuity and stability of the vehicle remote control.

[0028] Combined with the following Figure 1 The vehicle remote control method in the embodiment of the present application is described in detail. Figure 1 As shown, the vehicle remote control method 100 may include steps: S110-S120.

[0029] It should be noted that the vehicle remote control method 100 can be applied to a vehicle-mounted T-BOX. A vehicle-mounted T-BOX is a telematics device installed on a vehicle, and the vehicle-mounted T-BOX can be used to realize communication between the vehicle and an external terminal device, that is, the vehicle can be remotely controlled through the T-BOX.

[0030] In some implementations, the vehicle-mounted T-BOX can be communicatively connected with a target cloud platform, the target cloud platform is communicatively connected with a terminal device, the target cloud platform can be used to receive and store remote control instructions from the terminal device, the target cloud platform can refer to a cloud platform maintained by the manufacturer of the vehicle, and the target cloud platform can be called a telematics service provider (TSP) cloud platform.

[0031] The vehicle external terminal device in the embodiment of the present application may refer to any type of vehicle external terminal device mentioned above.

[0032] In some implementations, the vehicle-mounted T-BOX and the target cloud platform may be connected via a cellular network communication or a satellite network communication, and this application does not impose any specific restrictions on this.

[0033] As an example, a satellite communication link between the vehicle-mounted T-BOX and the target cloud platform is provided with a gateway and a satellite. The target cloud platform is connected to the gateway in communication, the gateway is connected to the satellite in communication, and the satellite is connected to the vehicle-mounted T-BOX in communication, thereby forming a satellite communication link from the target cloud platform to the vehicle-mounted T-BOX.

[0034] The embodiment of the present application does not impose any specific limitation on the type of the gateway. For example, the gateway may be a fixed gateway, or a mobile gateway or a portable gateway.

[0035] The embodiment of the present application does not specifically limit the type of satellite. For example, the satellite may be a low-orbit satellite, or a high-orbit satellite. The satellite in the embodiment of the present application may be a Beidou satellite (such as a Beidou-3 satellite).

[0036] See also Figure 1 , in step S110, the communication status of the cellular network on the vehicle-mounted T-BOX is detected.

[0037] In the embodiment of the present application, the communication status of the cellular network on the vehicle-mounted T-BOX can be detected in real time so as to dynamically switch the communication network later. The present application does not impose any specific restrictions on the frequency of real-time detection of the communication status of the communication network. For example, the frequency of the real-time detection can be set to 1 time per second, 2 times per second, or 5 times per second.

[0038] The cellular network may be referred to as a cellular network or a mobile communication network. The cellular network may be, for example, a 2G network, a 4G network, or a 5G network, and this application does not make any specific restrictions on this.

[0039] The embodiments of the present application do not impose specific restrictions on the detection method of the cellular network communication status. As an example, the cellular network communication status can be determined by detecting the communication status of the cellular network communication link between the vehicle-mounted T-BOX and the target cloud platform. For example, a heartbeat packet is periodically sent to the target cloud platform through the cellular network communication link between the vehicle-mounted T-BOX and the target cloud platform; if the response time of the heartbeat packet exceeds the first threshold, it is determined that the cellular network is in an unavailable state. Of course, if the response time of the heartbeat packet does not exceed the first threshold, it is determined that the cellular network is in an available state. The first threshold can be set according to demand, and the first threshold can be, for example, 2 seconds or 5 seconds, and the present application does not impose specific restrictions on this. It should be understood that a heartbeat packet may refer to a small data packet periodically sent to the target cloud platform, and the heartbeat packet can be used to determine whether the connection of the cellular network communication link between the vehicle-mounted T-BOX and the target cloud platform is still valid.

[0040] It should be noted that after receiving the heartbeat packet, the target cloud platform will reply a response message to the vehicle-mounted T-BOX, and the response message may be, for example, an ACK signal. The response time of the heartbeat packet may refer to the time interval from sending the heartbeat packet to receiving the response message.

[0041] As another example, the communication status of the cellular network can also be determined by detecting the communication quality of the cellular network. For example, the communication quality of the cellular network on the vehicle-mounted T-BOX can be directly detected; if the communication quality of the cellular network on the vehicle-mounted T-BOX is less than the second threshold, it is determined that the cellular network is in an unavailable state. Of course, if the communication quality of the cellular network on the vehicle-mounted T-BOX is not less than the second threshold, it is determined that the cellular network is in an available state. The second threshold can be set as required.

[0042] In some implementations, the communication quality of the cellular network on the vehicle-mounted T-BOX may be determined based on the signal strength and / or signal transmission delay of the cellular network on the vehicle-mounted T-BOX.

[0043] In some implementations, when the communication quality of the cellular network on the vehicle T-BOX is determined based on the signal strength of the cellular network on the vehicle T-BOX, the second threshold is a signal strength threshold, and the second threshold can be set to be greater than or equal to -70dBm, for example.

[0044] In some implementations, when the communication quality of the cellular network on the vehicle-mounted T-BOX is determined based on the signal transmission delay of the cellular network on the vehicle-mounted T-BOX, the second threshold is the signal transmission delay threshold, and the second threshold can be set to less than or equal to 100 milliseconds, for example.

[0045] In step S120, if the cellular network is unavailable and the vehicle-mounted T-BOX has successfully located the communication signal of the satellite network, remote control instructions from the vehicle's external terminal device are received based on the satellite communication network to achieve remote control of the vehicle.

[0046] In some implementations, the present application can detect the communication status of the cellular network on the vehicle-mounted T-BOX in real time. If the cellular network is detected to be unavailable and the vehicle-mounted T-BOX has successfully located the communication signal of the satellite network, it switches to the satellite network to receive remote control commands from the vehicle's external terminal devices. Of course, if it is detected that the vehicle-mounted T-BOX cannot locate the communication signal of the satellite network, it switches back to the cellular network to receive remote control commands from the vehicle's external terminal devices. In other words, the present application is a process of real-time detection of network quality (such as real-time detection of the network quality of the cellular network and / or satellite network) and dynamic network switching.

[0047] That the vehicle-mounted T-BOX has successfully located the communication signal of the satellite network may mean that the vehicle-mounted T-BOX has successfully locked the satellite signal, that is, the vehicle-mounted T-BOX can access the satellite communication network.

[0048] In some implementations, the satellite communication network may be a Beidou satellite communication network (eg, BeiDou III communication network), and remote control commands from terminal devices outside the vehicle may be received based on the satellite communication network, including: receiving remote control commands in short message format based on the satellite communication network.

[0049] In an embodiment of the present application, a terminal device outside the vehicle can realize remote control of the vehicle through remote control commands, and the remote control may include but is not limited to: door control, engine control, alarm function, vehicle air conditioning control, emergency rescue, etc.

[0050] From the above content, it can be seen that in the vehicle remote control scenario, this solution detects the availability status of the cellular network and the satellite signal positioning status. When the cellular network is unavailable and the satellite signal has been successfully located, it uses the satellite communication network to receive remote control commands, thereby helping to ensure the continuity and stability of vehicle remote control.

[0051] It should be noted that in the embodiment of the present application, the terminal device outside the vehicle can communicate with the target cloud platform through a cellular network. In this way, the terminal device outside the vehicle does not rely on the satellite communication module, and can also transmit remote control commands through a satellite network or a cellular network, thereby reducing the hardware requirements for the terminal device outside the vehicle and reducing communication costs.

[0052] In some implementations, after receiving remote control instructions based on the satellite communication network, if the cellular network returns to a stable and available state, the cellular network communication link can be switched to receive the remote control instructions, thereby reducing communication delays and communication costs. For example, if the cellular network is in an available state for a time greater than a third threshold (indicating that the cellular network is in a stable and available state), it is switched to receiving remote control instructions through the cellular network to achieve remote control of the vehicle. The third threshold can be set according to demand, and the third threshold can be, for example, 5 seconds or 10 seconds, and this application does not impose specific restrictions on this.

[0053] Considering that the target cloud platform is usually unable to actively send remote control instructions to the vehicle-mounted T-BOX through the satellite communication link between the target cloud platform and the vehicle-mounted T-BOX (for example, the communication link between the target cloud platform and the signal gateway is usually disconnected). In this case, the present application proposes a method for obtaining remote control instructions, including: sending a query request message to the target cloud platform through a satellite communication link, the query request message is used to indicate the query of the remote control instructions of the terminal device to the target cloud platform; receiving remote control instructions from the target cloud platform based on the satellite communication link between the vehicle-mounted T-BOX and the target cloud platform, including: in response to the target cloud platform receiving the query request message, and the target cloud platform storing the remote control instructions, the remote control instructions are received through the satellite communication link. In other words, the present application can open up the communication link between the target cloud platform and the vehicle-mounted T-BOX through the instruction query request message of the vehicle-mounted T-BOX. It should be understood that in the embodiment of the present application, the vehicle-mounted T-BOX can periodically send the above-mentioned query request message to the target cloud platform through the satellite communication link. The query cycle of the remote control instruction can be set according to demand, and the present application does not make specific restrictions on this.

[0054] In some implementations, after the vehicle-mounted T-BOX receives the remote control command, the remote control command can be sent to the body control module (BCM) controller in the vehicle through the central gateway module (CGW) controller to achieve remote control of the vehicle.

[0055] The following describes the embodiments of the present application in more detail with reference to specific examples. Figure 2 It is only to help those skilled in the art understand the embodiments of the present application, rather than to limit the embodiments of the present application to the specific values ​​or specific scenarios illustrated. Those skilled in the art can obviously make various equivalent modifications or changes based on the examples given, and such modifications or changes also fall within the scope of the embodiments of the present application.

[0056] Figure 2 Schematic diagram of the architecture of a vehicle remote control communication system provided by an embodiment of the present application. Figure 2 The vehicle remote control communication system includes a terminal device 210, a TSP cloud platform 220, a satellite network 230 and a vehicle 240.

[0057] The terminal device 210 is connected to the TSP cloud platform 220 through a mobile communication network (i.e., a cellular network) for data transmission. The terminal device 210 can be any type of vehicle external terminal device mentioned above. The TSP cloud platform 220 can be, for example, the target cloud platform mentioned above.

[0058] In some implementations, the TSP cloud platform 220 can be connected to the vehicle-mounted T-BOX 250 in the vehicle 240 through a mobile communication network to achieve data (such as remote control commands) transmission between the TSP cloud platform 220 and the vehicle 240; in other implementations, the TSP cloud platform 220 can also be connected to the vehicle-mounted T-BOX 250 in the vehicle 240 through a satellite communication network 230 to achieve data (such as remote control commands) transmission between the TSP cloud platform 220 and the vehicle 240.

[0059] In some implementations, the satellite network 230 may include a gateway 231 and a satellite 232, the TSP cloud platform 220 is communicatively connected to the gateway 231, the gateway 231 is communicatively connected to the satellite 232, and the satellite 232 is communicatively connected to the vehicle-mounted T-BOX 250 of the vehicle 240 to form a satellite communication link. It should be understood that the satellite communication link between the TSP cloud platform 220 and the vehicle-mounted T-BOX 250 may refer to the satellite communication link between the gateway 231 and the vehicle-mounted T-BOX 250, and the TSP cloud platform 220 and the gateway 231 are mobile communication links conducted through a mobile communication network. The satellite 232 may be, for example, a BeiDou-3 satellite.

[0060] In some implementations, the vehicle-mounted T-BOX 250 may include a satellite communication module 251, a mobile communication module 252, and a controller 253. The satellite communication module 251 may be connected to the TSP cloud platform 220 via a satellite communication network. The mobile communication module 252 may be connected to the TSP cloud platform 220 via a mobile communication network.

[0061] The controller 253 may be, for example, a microcontroller unit (MCU) or a central processing unit. This application does not impose any specific restrictions on this. The controller 253 may be used to manage the communication between the vehicle-mounted T-BOX 250 and the outside world. For example, the controller 253 may receive and send and process data from the BCM controller 270.

[0062] In some implementations, the vehicle 240 further includes a CGW controller 260 and a BCM controller 270. The controller 253 of the vehicle-mounted T-BOX 250 can send remote control instructions to the BCM controller 270 in the vehicle 240 through the CGW controller 260 to achieve remote control of the vehicle 240.

[0063] In some implementations, the vehicle-mounted T-BOX 250, the CGW controller 260, and the BCM controller 270 are connected to each other through an in-vehicle network, which may be, for example, a controller area network (CAN) or Ethernet.

[0064] In some implementations, inside the vehicle-mounted T-BOX 250, the controller 253 and the mobile communication module can be connected to each other via a serial peripheral interface (SPI) protocol, and the satellite communication module 251 and the mobile communication module 252 can be connected to each other via a universal asynchronous receiver-transmitter (UART) protocol.

[0065] Combine the following Figure 2 The vehicle remote control method in the embodiment of the present application is described in detail. The vehicle remote control method may include the following steps: 201-206.

[0066] In step 201: the communication link between the TSP cloud platform 220 and the vehicle-mounted T-BOX 250 is set to the mobile network by default. After the vehicle-mounted T-BOX 250 is powered on, it actively connects to the TSP cloud platform 220 through the mobile communication module 252, and periodically sends a heartbeat packet to the TSP cloud platform 220, and the heartbeat period is T1.

[0067] In step 202: the TSP cloud platform 220 needs to count the response time of the heartbeat packet. If the response time of the heartbeat packet reaches T2, it can be determined that the mobile communication link between the TSP cloud platform 220 and the vehicle-mounted T-BOX 250 has failed, and starts waiting for the vehicle-mounted T-BOX 250 to report a remote control command query request through the satellite network.

[0068] In step 203: the vehicle-mounted T-BOX 250 may periodically monitor the mobile network signal strength and the satellite signal positioning status of the satellite 232, and the monitoring period is T3.

[0069] In step 204 : if the mobile network signal strength is lower than the set threshold value Q1 and the continuous unavailable time exceeds the set threshold value M1 , the satellite signal positioning status of the satellite 232 is checked.

[0070] In step 205: if the vehicle-mounted T-BOX 250 has successfully located the satellite signal of the satellite 232, it switches to the satellite network 230, and the vehicle-mounted T-BOX 250 starts the satellite command query timer, and periodically queries the TSP cloud platform 220 for the remote control command of the vehicle 240 through the satellite network 230, and the query period is T4.

[0071] In step 206: If the mobile network recovers the signal, for example, the mobile network signal strength reaches the set threshold Q2, and the continuous available time exceeds the set threshold M2, the satellite command query timer is stopped, the mobile network is switched back, and the connection with the TSP cloud platform is re-established, and the mobile communication link between the TSP cloud platform 220 and the vehicle-mounted T-BOX 250 is used to receive the remote control command.

[0072] It should be noted that the above-mentioned thresholds can be set according to needs, and this application does not impose any specific restrictions on this.
