Description

Technical Field

[0001] The present invention relates to the technical field of vehicle parking, and particularly to a vehicle remote memory parking control system and method based on mobile communication. Background Art

[0002] With the increasing density of urban traffic, parking difficulty has become an increasingly prominent problem. Especially in commercial areas and residential areas, finding a parking space not only takes time but also often causes traffic congestion. In addition, manual parking not only places high demands on the driving skills of drivers but also increases the risk of collisions during operation in narrow or crowded spaces. Although the existing remote parking systems can alleviate these problems to a certain extent, most systems still rely on short-distance communication between the vehicle and local sensors, which limits the application scenarios and efficiency of the parking system, and is prone to unstable information transmission in environments with weak network signals or severe interference.

[0003] The main technical problems faced by current automatic parking technologies include how to provide accurate vehicle positioning and navigation in complex and dynamic urban environments, how to achieve precise parking under remote control, and how to ensure stable communication between the vehicle and the control platform under various network conditions. Existing automatic parking systems mostly rely on on-vehicle sensors, and their parking decision-making and execution capabilities are limited by the performance of the sensors and the communication delay between the vehicle and the control center, and they cannot complete stable long-distance parking.

[0004] Therefore, there is an urgent need to develop a new type of remote parking control system and method that can utilize high-speed and low-latency 5G communication technology to achieve a safer, more efficient, and intelligent remote parking solution through the integration of advanced data processing and real-time monitoring technologies. Summary of the Invention

[0005] Based on the above purposes, the present invention provides a vehicle remote memory parking control system and method based on mobile communication.

[0006] A vehicle remote memory parking control system based on mobile communication includes a remote service platform, a remote mobile terminal communicating with the remote service platform, a parking control module, and an in-vehicle information terminal; the in-vehicle information terminal includes a vehicle machine SOC module and a vehicle machine MCU module connected to the vehicle machine SOC module, the vehicle machine SOC module communicates with the remote service platform through a 5G communication module, and the vehicle machine MCU module communicates with the parking control module through a gateway; the parking control module includes a memory parking control module.

[0007] The remote mobile terminal is used for the user to issue parking control instructions, view parking status information, and surrounding real-time images.

[0008] The remote service platform is used for cloud service management, sending downlink control instructions, receiving parking status information, and managing real-time video streams;

[0009] The in-vehicle SOC module is used for vehicle-end management of uplink and downlink control instructions, receiving real-time video streams, decoding, and pushing the video streams to the remote service platform;

[0010] The in-vehicle MCU module is used for communicating with other vehicle-end controllers and confirming whether the vehicle end meets the parking conditions;

[0011] The parking control module is used for forwarding real-time video streams to the in-vehicle SOC module. The memory parking control module stores a memory parking route and controls the vehicle end to perform memory parking operations according to the memory parking route.

[0012] A vehicle remote memory parking control method based on mobile communication includes the following steps:

[0013] S1. Assemble the parking control system: Install an in-vehicle information terminal, a parking control module, and a sensor module at the vehicle end, and equip a remote service platform and a remote mobile terminal that communicates with the remote service platform. The in-vehicle information terminal includes an in-vehicle SOC module and an in-vehicle MCU module connected to the in-vehicle SOC module. The in-vehicle SOC module communicates with the remote service platform through a 5G communication module. The in-vehicle MCU module communicates with the parking control module through a gateway. The sensor module is connected to the parking control module;

[0014] S2. Send a parking start instruction and detect the communication status of the in-vehicle information terminal: Send a parking start instruction to the remote service platform through the remote mobile terminal and transmit it to the 5G communication module. The 5G communication module detects the communication status of the 5G / 4G signal. If the remote memory parking communication control conditions are not met, the control is interrupted and feedback is given to the remote mobile terminal through the remote service platform. If the 5G / 4G signal status meets the communication control conditions, proceed to the next step;

[0015] S3. Detect the communication status of the in-vehicle MCU module and confirm whether the vehicle end meets the parking conditions: After receiving the remote parking start instruction, the 5G communication module transmits it to the in-vehicle MCU module through the in-vehicle SOC module. The in-vehicle MCU module detects whether the communication with other vehicle-end controllers is normal and confirms whether the vehicle end meets the parking conditions. The parking conditions include but are not limited to the vehicle door being closed and the vehicle being in a drivable state. If the communication status is normal and the parking conditions are met, proceed to the next step; otherwise, interrupt the control and feedback to the remote mobile terminal through the remote service platform;

[0016] S4. The parking control module receives the remote parking start command and feeds it back to the remote mobile terminal: The in-vehicle MCU module transmits the remote parking start command to the parking control module through the gateway. After receiving it, the parking control module feeds back the signal of successfully starting remote parking to the remote mobile terminal through the vehicle information terminal and the remote service platform;

[0017] S4.1. The remote mobile terminal sends a start remote parking command to the parking control module: The remote mobile terminal issues a start remote parking command to the remote service platform. The remote service platform then continuously sends a start remote parking command to the 5G communication module until parking is completed. After receiving the start remote parking command, the 5G communication module transmits it to the in-vehicle SOC module, and then through the in-vehicle MCU module, sends a start remote parking command to the parking control module. If the 5G communication module does not receive the start remote parking command, the in-vehicle MCU module stops sending the start remote parking command;

[0018] S4.2. The remote mobile terminal sends a video streaming start command to the in-vehicle SOC module: The video stream collected by the sensor module is transmitted to the parking control module. The remote mobile terminal issues a video streaming start command to the remote service platform and transmits it to the in-vehicle SOC module through the 5G communication module. After decoding the video stream forwarded by the in-vehicle SOC module to the parking control module, the video is then streamed to the remote service platform through the 5G communication module for the remote mobile terminal to view;

[0019] S5. The parking control module controls the vehicle to perform remote parking operations: After receiving the start remote parking command, the parking control module controls other execution modules to start the remote parking operation of the vehicle;

[0020] S6. The parking control module feeds back the parking status to the remote service platform: During parking, the parking control module transmits the vehicle parking status to the in-vehicle MCU module, and then through the in-vehicle SOC module and the 5G communication module, feeds it back to the remote service platform. The remote mobile terminal obtains and views the vehicle parking status from the remote service platform. The vehicle parking status includes but is not limited to the remaining mileage of the route, the body status, and the vehicle speed status;

[0021] S7. Complete the remote parking operation: After the vehicle drives into the parking space, the parking control module controls other execution modules to make the vehicle enter the parking state, and transmits the signal of completed parking to the in-vehicle MCU module, which is then fed back to the remote service platform through the in-vehicle MCU module and the 5G communication module for the remote mobile terminal to view. At the same time, the 5G communication module stops pushing the video stream to the remote service platform.

[0022] Further, step S1 further includes the following steps:

[0023] The parking control module includes a memory parking control module, and the memory parking control module stores a memory parking route;

[0024] S5 further includes the following steps:

[0025] After receiving the start remote parking instruction, the parking control module transmits it to the memory parking control module. The memory parking control module controls other execution modules according to the preset memory parking route and in combination with the data collected by the sensor module, so that the vehicle starts the remote memory parking operation.

[0026] S5 further includes the following steps:

[0027] The sensor module includes several panoramic cameras, ultrasonic radars, and millimeter-wave radars;

[0028] The panoramic camera is used to capture real-time video images around the vehicle. The ultrasonic radar measures the distance of nearby obstacles through the reflection of high-frequency sound waves. The millimeter-wave radar detects the speed and distance of distant objects by emitting electromagnetic waves and measuring the signal strength and time of the reflected signals.

[0029] The further steps for the 5G communication module to detect the 5G / 4G signal communication status in S2 are as follows:

[0030] S2.1: The 5G communication module accesses the 5G-NR core network, and the 5G communication module continuously monitors the signal strength and network quality parameters of the surrounding 5G-NR network through the built-in network scanning module, including signal strength, signal-to-interference ratio, and signal transmission delay;

[0031] S2.2: According to the monitored network conditions, use the dynamic frequency band selection algorithm to select the optimal frequency band in the preset frequency band list to ensure signal stability and high-efficiency data transmission. The decision formula of the dynamic frequency band selection algorithm is: where F opt is the selected optimal frequency band; F i is the candidate frequency band; W i is the weight of the frequency band F i , representing the comprehensive score of signal quality; Q i is the quality parameter of the frequency band F i ;

[0032] S2.3: Establish a long connection with the remote service platform through the TCP protocol to ensure the real-time nature of control instruction and data transmission. The steps to establish a TCP connection are: initialize connection parameters, send a handshake signal, confirm the establishment of the connection, and start data transmission;

[0033] S2.4: During the data transmission process, the 5G communication module continuously monitors the network quality parameters. When it detects that the quality parameters of the 5G network are lower than the preset threshold, it triggers the network switching mechanism; this network switching mechanism is used to automatically switch to the 4G network to ensure the continuity and low latency of data transmission. The network switching steps are: pause the current data transmission, switch to the standby 4G network band, re-establish the TCP connection, and resume data transmission;

[0034] S2.5: After the network switching is completed, the 5G communication module continues to monitor the quality parameters of the 4G network, and when the 5G network resumes to the preset quality standard, it switches back to the 5G network.

[0035] Advantages of the present invention:

[0036] In the present invention, by integrating the high-speed 5G communication technology with the advanced vehicle-mounted sensor network, the response speed and data processing ability of the parking system are significantly improved. This system utilizes the low-latency characteristic of 5G to enable the transmission of real-time video streams, providing real-time monitoring capabilities for remote users and greatly enhancing the user's sense of control and trust in the parking process.

[0043] Embodiment 1

[0044] As Figure 1 shown, a vehicle remote memory parking control system based on mobile communication includes a remote service platform 2, a remote mobile terminal 1 communicating with the remote service platform, a parking control module, and an in-vehicle information terminal; the in-vehicle information terminal includes a vehicle machine SOC module 4 and a vehicle machine MCU module 5 connected to the vehicle machine SOC module 4. The vehicle machine SOC module 4 communicates with the remote service platform 2 through a 5G communication module 3, and the vehicle machine MCU module 5 communicates with the parking control module through a gateway 6; the parking control module includes a memory parking control module 7.

[0045] The remote mobile terminal 1 is used for the user to issue parking control instructions, view parking status information, and surrounding real-time images.

[0046] The remote service platform 2 is used for cloud service management, sending downlink control instructions, receiving parking status information, and managing real-time video streams.

[0047] The vehicle machine SOC module 4 is used for managing uplink and downlink control instructions at the vehicle end, receiving real-time video streams, decoding, and pushing the video streams to the remote service platform.

[0048] The vehicle machine MCU module 5 is used for communicating with other vehicle-end controllers and confirming whether the vehicle end meets the parking conditions.

[0049] The parking control module is used for forwarding real-time video streams to the vehicle machine SOC module 4. The memory parking control module 7 stores a memory parking route and controls the vehicle end to perform memory parking operations according to the memory parking route. The memory parking control module 7 can control other vehicle-end controllers, such as the steering system, accelerator, and brake, etc.

[0050] To collect environmental information, the system is also equipped with a sensor module. The sensor module includes multiple panoramic cameras 9. The panoramic cameras 9 are connected to the parking control module through GMSL lines. The parking control module can receive the data collected by the sensor module to assist in performing parking operations and can also forward the video stream to the vehicle machine SOC module 4.

[0051] In this embodiment, the remote mobile terminal 1 can be a mobile phone APP, and the APP calls the HTTPS interface; the remote service platform 2 selects the TSP platform; the remote mobile terminal 1 completes the parking instruction connection by calling the TSP interface through the HTTPS network connection, and completes the video stream pulling through the RTMP real-time message transmission protocol to connect with the TSP.

[0052] The 5G communication module 3 accesses the 5G core network through 5G-NR. If the 5G network does not meet the control requirements, it switches to the 4G network for receiving remote parking control instructions and video streaming; a TCP long connection is used between the remote service platform 2 and the 5G communication module 3 to transmit parking control instructions, and the video stream uses the RTMP real-time message transmission protocol based on the TCP protocol to transmit the video stream.

[0053] The 5G communication module 3 and the in-vehicle MCU module 5 are connected to the in-vehicle SOC module 4 through UART / SPI communication.

[0054] The in-vehicle MCU module 5 is connected to the gateway (6) through the CAN-FD bus using a CAN-FD transceiver and communicates with other vehicle-end controllers using CAN-FD.

[0055] The parking control module is connected to the vehicle information terminal through the gateway 6 and connects to other vehicle-end control modules in the form of a CAN-FD bus to complete memory parking.

[0056] This system is applicable to a parking environment of a vehicle that conforms to the parking environment adapted to the memory parking route stored in the memory parking control module 7. The specific control method is as follows:

[0057] As Figure 2 shown, a vehicle remote memory parking control method based on mobile communication includes the following steps:

[0058] S1. Assemble the parking control system: Install a vehicle information terminal, a parking control module, and a sensor module at the vehicle end, and equip a remote service platform 2 and a remote mobile terminal 1 that communicates with the remote service platform. The vehicle information terminal includes an in-vehicle SOC module 4 and an in-vehicle MCU module 5 connected to the in-vehicle SOC module 4. The in-vehicle SOC module 4 communicates with the remote service platform 2 through the 5G communication module 3. The in-vehicle MCU module 5 communicates with the parking control module through the gateway 6. The sensor module is connected to the parking control module. The parking control module includes a memory parking control module 7, and the memory parking control module 7 stores a memory parking route;

[0059] During the installation process, software configuration and debugging are performed on each module to ensure normal communication and coordination between the 5G communication module 3 and the remote service platform 2, and between the in-vehicle MCU module and the parking control module. Preliminary tests are carried out through the on-vehicle diagnostic system to ensure that the functions and performance of each module meet the design requirements, and to ensure reliable and efficient operation in the vehicle, thus realizing the basic architecture construction of the vehicle remote parking control system;

[0060] S2. Send the parking start command and detect the communication status of the in-vehicle information terminal: After the vehicle travels to the starting point of the memory route, the user sends a parking start command from the remote mobile terminal 1 to the remote service platform 2, which is then transmitted to the 5G communication module 3. The 5G communication module 3 detects the communication status of the 5G / 4G signal. If the final 4G-LTE RSRP signal value is lower than -100 dbm, the remote memory parking communication control condition is not met, and the control is interrupted and feedback to the remote mobile terminal 1 through the remote service platform 2. If the 5G / 4G signal status meets the communication control condition, proceed to the next step;

[0061] S3. Detect the communication status of the in-vehicle MCU module and confirm whether the vehicle end meets the parking conditions: After receiving the remote parking start command, the 5G communication module 3 is transmitted to the in-vehicle MCU module 5 through the in-vehicle SOC module 4. The in-vehicle MCU module 5 detects whether the communication with other vehicle end controllers is normal and confirms whether the vehicle end meets the parking conditions. For example, the vehicle is currently in the door closed state, the vehicle is in the drivable READY state, the gear is in the P gear, and the electronic handbrake is pulled up. If the communication status is normal and the parking conditions are met, proceed to the next step; otherwise, interrupt the control and feedback to the remote mobile terminal 1 through the remote service platform 2;

[0062] S4. The parking control module receives the remote parking start command and feedbacks it to the remote mobile terminal 1: The in-vehicle MCU module 5 sends a CAN-FD signal of the remote parking start command to the bus. After receiving it, the parking control module activates the memory parking mode and feedbacks a signal indicating the success of starting remote parking on the bus. After receiving it, the in-vehicle MCU module 5 is feedback to the remote mobile terminal 1 through the in-vehicle information terminal and the remote service platform 2;

[0063] S4.1. The remote mobile terminal 1 sends a start remote parking instruction to the parking control module: The remote mobile terminal 1 sends a start remote parking instruction to the remote service platform 2, and the remote service platform 2 will continuously send a start remote parking instruction to the 5G communication module 3 until parking ends. The start remote parking instruction can be sent once per second. After the 5G communication module 3 receives more than 3 frames of start remote parking instructions, it transmits them to the in-vehicle SOC module 4, and then through the in-vehicle MCU module 5, it sends a start remote parking instruction to the parking control module. If the 5G communication module 3 does not receive or does not receive more than 3 frames of start remote parking instructions, the in-vehicle MCU module 5 stops sending the start remote parking instruction;

[0064] S4.2. The remote mobile terminal 1 sends a start video streaming instruction to the in-vehicle SOC module 4: The video stream collected by the sensor module is transmitted to the parking control module. The remote mobile terminal 1 sends a start video streaming instruction to the remote service platform 2 and transmits it to the in-vehicle SOC module 4 through the 5G communication module 3. The in-vehicle SOC module 4 receives the video stream forwarded by the parking control module. After decoding, the in-vehicle SOC module 4 uses the cloud service mobile live SDK to initiate a streaming service to the TSP platform through the RTMP protocol, and streams the aforementioned video to the remote service platform 2 through the 5G communication module 3 for the remote mobile terminal 1 to view. The remote mobile terminal 1 uses the mobile live SDK built into the APP application to pull the video stream on the TSP platform and displays the real-time video stream on the mobile terminal (mobile phone APP);

[0065] Through the method of the above steps, it is ensured that the in-vehicle SOC module 4 can efficiently and reliably transmit the real-time video stream, provide it to the remote mobile terminal 1 for real-time monitoring, improve the controllability and safety of the remote memory parking process, and provide the user with an intuitive operation experience and reliable data support;

[0066] S5. The parking control module controls the vehicle end to perform remote parking operations: After receiving the CAN-FD signal of the start remote parking instruction, the parking control module transmits it to the memory parking control module 7. According to the preset memory parking route and combined with the data collected by the sensor module, the memory parking control module 7 controls other execution modules to make the vehicle start remote memory parking operations. For example, it controls the vehicle end to switch to the D gear and release the EPB electronic handbrake, and the remote memory parking starts. If the parking control module does not receive the CAN-FD signal of the start remote parking instruction, the remote memory parking is paused;

[0067] During the remote memory parking process, when encountering human intervention, gear shifting intervention, the door being opened, the handbrake being pulled up, or a moving obstacle intruding, the system will exit the remote memory parking. At the same time, the memory parking control module 7 will feedback a parking anomaly CAN-FD signal to the bus, which is transmitted through the vehicle information terminal and the remote service platform 2 for the remote mobile terminal 1 to view. The frequency at which the 5G communication module 3 reports the parking anomaly to the remote service platform 2 can be once per second;

[0068] S6. The parking control module feeds back the parking status to the remote service platform 2: During the parking process, the parking control module transmits the vehicle parking status to the in-vehicle MCU module 5, and then it is fed back to the remote service platform 2 through the in-vehicle SOC module 4 and the 5G communication module 3. The remote mobile terminal 1 obtains and views the vehicle parking status from the remote service platform 2. The vehicle parking status includes but is not limited to the remaining mileage of the route, the vehicle body status, and the vehicle speed status. The frequency at which the 5G communication module 3 reports to the remote service platform 2 can be once per second;

[0069] S7. Complete the remote parking operation: After the vehicle drives into the parking space, the parking control module controls other execution modules to make the vehicle enter the parking state. For example, the parking control module controls the vehicle end to control other execution modules to switch the vehicle gear to the P gear, tighten the EPB electronic parking brake, turn off the engine, close the windows, and perform the locking operation, and transmits the signal indicating the completion of parking to the in-vehicle MCU module 5, which is fed back to the remote service platform 2 through the in-vehicle MCU module 5 and the 5G communication module 3 for the remote mobile terminal 1 to view. At the same time, the 5G communication module 3 stops pushing the video stream to the remote service platform 2, and the remote mobile terminal 1 stops pulling the video stream and closes the panoramic interface.

[0070] S5 further includes the following steps:

[0071] The sensor module includes several panoramic cameras, ultrasonic radars, and millimeter-wave radars. The panoramic cameras are transmitted to the parking control module through GMSL cables, and the ultrasonic radars are transmitted to the parking control module through hard-wired I / O ports;

[0072] The panoramic cameras are used to capture real-time video images around the vehicle. The ultrasonic radars measure the distance to nearby obstacles through the reflection of high-frequency sound waves, and the millimeter-wave radars detect the speed and distance of distant objects by emitting electromagnetic waves and measuring the intensity and time of the reflected signals.

[0073] Through the method of the above steps, the efficient fusion and accurate analysis of multi-sensor data are achieved, the perception ability of the vehicle surrounding environment is improved, thus providing reliable data support for remote parking control, and enhancing the safety and intelligence of the system.

[0077] S2.2: According to the monitored network conditions, the dynamic frequency band selection algorithm is used to select the optimal frequency band from the preset frequency band list to ensure signal stability and high-efficiency data transmission. The decision formula of the dynamic frequency band selection algorithm is: where F opt is the selected optimal frequency band; F i is the candidate frequency band; W i is the weight of the frequency band F i indicating the comprehensive score of signal quality; Q i is the quality parameter of the frequency band F i ;

[0078] S2.3: Establish a long connection with the remote service platform 2 through the TCP protocol to ensure the real-time nature of control instruction and data transmission. The steps for establishing a TCP connection are: initializing connection parameters, sending a handshake signal, confirming the establishment of the connection, and starting data transmission;

[0079] S2.4: During the data transmission process, the 5G communication module 3 continuously monitors the network quality parameters. When it detects that the quality parameters of the 5G network are lower than the preset threshold, the network switching mechanism is triggered; this network switching mechanism is used to automatically switch to the 4G network to ensure the continuity and low latency of data transmission. The network switching steps are: pausing the current data transmission, switching to the standby 4G network frequency band, re-establishing a TCP connection, and resuming data transmission;

[0080] S2.5: After the network switching is completed, the 5G communication module continues to monitor the quality parameters of the 4G network and switches back to the 5G network when the 5G network resumes to the preset quality standard.
