Description

Technical Field

[0001] One or more embodiments of the present disclosure generally relate to electronic devices and operating methods of electronic devices for supporting vehicle-to-everything (V2X) communication, wherein V2X communication is used as the basis for autonomous driving vehicle technology, cooperative-intelligent transport system (C-ITS) technology, etc. Background Art

[0002] Vehicle-to-everything (V2X) communication technology is a technology that allows vehicles to exchange information with entities such as other vehicles, mobile devices, and electronic components embedded in the road via wired or wireless networks.

[0003] V2X communication technology is divided into two main communication technologies: dedicated short range communication (DSRC) technology and cellular V2X (C-V2X) technology. DSRC and C-V2X technologies use the same 5.9GHz frequency band but are based on different technical standards. DSRC technology is based on the IEEE 802.11 standard, while C-V2X is based on cellular communication standards such as the third generation (3G), fourth generation (4G) and fifth generation (5G) standards.

[0004] In a geographical area where different V2X communication technologies (such as DSRC and C-V2X technologies) are combined and used, or in a geographical area where areas using two different V2X communication technologies are adjacent to each other, it may be necessary to be able to quickly switch between the two V2X communication technologies when supporting the two V2X communication technologies in order to obtain better V2X communication performance. However, the technologies that have been developed so far assume that one or the other of the two V2X communication technologies is selectively used depending on the country or region, so that the two V2X communication technologies are not used simultaneously in the same area. Therefore, a method of switching between different V2X communication technologies is not considered. Summary of the invention

[0005] Technical issues

[0006] In electronic devices installed in vehicles to support dedicated short-range communication (DSRC) technology and cellular vehicle-to-everything (C-V2X) technology, it is necessary to reduce the area occupied by devices such as antennas installed in the vehicle and the cost of the antennas. According to certain embodiments of the present disclosure, these reductions can be achieved by switching between DSRC and C-V2X technologies and using a shared antenna for DSRC and C-V2X.

[0007] Technical Solutions

[0008] According to an embodiment of the present disclosure, an electronic device installed to a vehicle to support wireless mobile communication of the vehicle includes: a DSRC module, configured to perform wireless communication by using DSRC technology; a C-V2X module, configured to perform wireless communication by using C-V2X technology; an antenna; and a processor, configured to control a switch to connect the DSRC module or the C-V2X module to the antenna.

[0028] Invention Mode

[0029] Embodiments of the present disclosure will now be described more fully below with reference to the accompanying drawings so that they can be easily implemented by those of ordinary skill in the art. However, embodiments of the present disclosure may have different forms and should not be construed as being limited to the embodiments of the present disclosure set forth herein. In addition, parts not related to the present disclosure are omitted to clarify the description of the embodiments of the present disclosure, and the same reference numerals in the accompanying drawings always represent the same elements.

[0030] Some embodiments of the present disclosure can be described according to function block components and various processing operations. Some or all of these function blocks can be implemented by any number of hardware and / or software components that perform specific functions. For example, the function blocks of the present disclosure can be implemented by one or more microprocessors or circuit components for performing certain functions. For example, the function blocks according to the present disclosure can be implemented with any programming or scripting language. The function blocks can be implemented using various algorithms executed on one or more processors. In addition, the present disclosure can adopt technologies in related fields for electronic configuration, signal processing and / or data processing.

[0031] In addition, the connecting lines or connectors shown in the various figures are intended to represent exemplary functional relationships and / or physical or logical couplings between components in the figures. In actual devices, the connections between components may be represented by alternative or additional functional relationships, physical connections or logical connections.

[0032] Throughout the disclosure, the expression "at least one of a, b, or c" means only a, only b, only c, a and b, a and c, b and c, all of a, b, and c, or variations thereof.

[0033] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0034] Figure 1 is a diagram for explaining V2X technology.

[0035] V2X, which stands for Vehicle-to-Everything, refers to the exchange of information between a vehicle and another entity, or the technology that enables such an exchange of information between them. Figure 1As shown, V2X communication technology can realize wireless communication between vehicle 100 and network 10 (vehicle-to-network (V2N) communication), wireless communication between vehicle 100 and infrastructure 20 (vehicle-to-infrastructure (V2I) communication), wireless communication between vehicle 100 and another vehicle 30 (vehicle-to-vehicle (V2V) communication), wireless communication between vehicle 100 and pedestrians 40 (vehicle-to-pedestrian (V2P) communication), etc.

[0036] As mentioned above, V2X communication technology includes dedicated short-range communication (DSRC) technology and cellular V2X (C-V2X) technology. Traditionally, in a specific country or region, only one of DSRC and C-V2X technologies is selected and used. However, in geographical areas where different V2X communication technologies (such as DSRC and C-V2X) are combined and used, or in geographical areas where areas using different V2X communication technologies are adjacent to each other, vehicles supporting these two V2X communication technologies can be used for better V2X communication performance. Because the two V2X communication technologies use the same 5.9GHz frequency band, two or more different antennas need to be used when the two V2X communication technologies are performed simultaneously. However, when V2X communication via two V2X communication technologies is performed using two or more different antennas, this may result in significant performance degradation due to mutual interference.

[0037] Therefore, the electronic device installed in the vehicle to support the wireless mobile communication of the vehicle according to the embodiment of the present disclosure can be configured to effectively perform a switching operation for turning on or off any one of the two V2X communication technologies when supporting the two V2X communication technologies. Therefore, an acceptable V2X performance can be provided, and since the antenna is shared between the two communication technologies, the space occupied by the antenna and the cost of the antenna can be reduced.

[0038] Figure 2 is a block diagram of an electronic device 200 according to an embodiment of the present disclosure.

[0039] According to an embodiment of the present disclosure, the electronic device 200 may include a telematics control unit (TCU) embedded in a vehicle to support wireless mobile communication of the vehicle. Telematics is a wireless communication technology that provides various information and diverse services for the vehicle, and TCU is a cellular communication device that includes multiple communication modules and is installed in the vehicle.

[0040] According to an embodiment of the present disclosure, the electronic device 200 may include a DSRC module 210 for performing wireless communication using the DSRC technology and a C-V2X module 220 for performing wireless communication using the C-V2X technology. Each of the DSRC module 210 and the C-V2X module 220 may include a V2X modem and a radio frequency (RF) transceiver.

[0041] According to an embodiment of the present disclosure, the electronic device 200 may include a processor 250 for controlling the switch 240 to connect any one of the DSRC module 210 or the C-V2X module 220 to the antenna 230. The switch 240 may be a radio frequency switch for connecting the DSRC module 210 and the C-V2X module 220 to the antenna 230. The antenna 230 may be one or a pair of antenna modules.

[0042] like Figure 2 As shown, the antenna 230 may be located outside the electronic device 200. For example, the electronic device 200 may be located inside a vehicle, and the antenna 230 may be located outside the vehicle. The electronic device 200 may be connected to the antenna 230 via a 5.9 GHz coaxial cable. However, the embodiments of the present disclosure are not limited thereto, and the antenna 230 may be included inside the electronic device 200.

[0043] The processor 250 controls some or all operations of the electronic device 200. The processor 250 can control the components included in the electronic device 200 so that the electronic device 200 can perform wired / wireless communication for the vehicle. The processor 250 can perform operations such as generation and interpretation of commands for driving the electronic device 200, arithmetic calculations, control, etc. The processor 250 may include a central processing unit (CPU) for processing data and a graphics processing unit (GPU) for processing image information. In addition, the processor 250 may support communication interfaces such as universal serial bus (USB), peripheral component interconnect (PCI), universal asynchronous receiver / transmitter (UART) or general-purpose input / output (GPIO). In addition, the processor 250 may include a microprocessor or any suitable type of processing circuit, such as one or more general-purpose processors (e.g., ARM-based processors), digital signal processors (DSPs), programmable logic devices (PLDs), application-specific integrated circuits (ASICs), field programmable gate arrays (FPGAs), graphics processing units (GPUs), video card controllers, etc. In addition, it will be recognized that when a general-purpose computer accesses the code for implementing the processing shown herein, the execution of the code converts the general-purpose computer into a special-purpose computer for performing the processing shown herein. Certain functions and steps provided in the accompanying drawings may be implemented in hardware, software, or a combination of both, and may be executed in whole or in part within the programming instructions of a computer. No claim element herein should be interpreted in accordance with the provisions of 35 USC § 112 (f) unless the element is explicitly stated using the phrase "means for..." In addition, the skilled person understands and appreciates that a "processor" or "microprocessor" may be hardware in the disclosure claimed for protection. Under the broadest reasonable interpretation, the attached claims are statutory subject matter consistent with 35 USC § 101.

[0044] although Figure 2 The electronic device 200 including one processor is shown, but the embodiments of the present disclosure are not limited thereto, and the electronic device 200 may include a plurality of processors. At least some operations and functions (to be described below) of the processor 250 may be performed by a plurality of processors.

[0045] According to an embodiment of the present disclosure, the antenna 230 may be an antenna module further including a power amplifier (PA) / low noise amplifier (LNA) for signal compensation, a switch for branching a signal, and a power detector circuit for providing feedback on power control.

[0046] In addition, according to an embodiment of the present disclosure, the antenna 230 may include a pair of sub-antennas for diversity transmission and diversity reception. However, the embodiment of the present disclosure is not limited thereto, and the antenna 230 may include three or more sub-antennas. The switch 240 may receive two output signals from the DSRC module 210 for the pair of sub-antennas and two output signals from the C-V2X module 220 for the pair of sub-antennas, and selectively output the two signals to the pair of sub-antennas.

[0047] The aforementioned diversity scheme is a communication scheme using two or more antennas, which can eliminate or reduce the fading that occurs during the propagation of radio waves, and can achieve communication with stronger and constant signal strength. This is achieved by combining the outputs of two or more received signals together. The transmission and reception performance in the diversity transmission / reception scheme achieved by transmitting or receiving the same signal via two or more antennas may be more than twice as good as the transmission and reception performance achieved using a single antenna.

[0048] According to an embodiment of the present disclosure, the processor 250 may select the best V2X communication technology according to various determination criteria, and perform V2X communication by using the selected V2X communication technology. For example, the processor 250 may select the best V2X communication technology based on the location information of the vehicle, information about the base station connected for cellular communication, comparison of periodically found DSRC and C-V2X signals, or surrounding environment information. Alternatively, the processor 250 may select the V2X communication technology based on user input, and perform V2X communication by using the selected V2X communication technology.

[0049] For example, according to an embodiment of the present disclosure, the processor 250 may select either the DSRC module 210 or the C-V2X module 220 based on the location information of the vehicle equipped with the electronic device 200, and control the switch 240 to connect the selected V2X module to the antenna 230. For example, the location information of the vehicle may include a global positioning system (GPS) signal of the vehicle. The processor 250 may select either the DSRC module 210 or the C-V2X module 220 as a module for V2X communication of a specific current location of the vehicle based on information about a V2X communication technology corresponding to the location of the vehicle and the location information of the vehicle.

[0050] Figure 3a2 is a view showing an example of a vehicle equipped with an electronic device 200 traveling in a geographical area adjacent to an area 301 supporting DSRC technology and an area 302 supporting C-V2X technology. According to an embodiment of the present disclosure, the electronic device 200 may obtain information about a V2X communication technology corresponding to the vehicle location from an internal memory or an external server. The information about the V2X communication technology corresponding to the vehicle location may include information about whether the area where the vehicle is located supports DSRC or C-V2X technology. The electronic device 200 may determine the location of the vehicle based on a received global positioning system signal, and select a V2X module, i.e., a DSRC module 210 or a C-V2X module 220, based on the V2X communication technology supported in the area corresponding to the vehicle location. The electronic device 200 may perform V2I communication with an infrastructure included in the area corresponding to the vehicle location by using the selected V2X module.

[0051] In another example, according to an embodiment of the present disclosure, the processor 250 may select the DSRC module 210 or the C-V2X module 220 based on information about a base station that performs cellular communication with the electronic device 200. The information about the base station may include location information of the base station, identification information of the base station, identification information of neighboring base stations, etc. The processor 250 may control the switch 240 to connect the antenna 230 to the DSRC module 210 or the C-V2X module 220. The processor 250 may select the DSRC module 210 or the C-V2X module 220 as a module for V2X communication with the base station based on information about a V2X communication technology corresponding to the base station.

[0052] Figure 3b 4 is a view showing a cell 403 obtained by dividing the coverage area of ​​cellular communication and a base station 401 installed in the cell 403. According to an embodiment of the present disclosure, the electronic device 200 may obtain information about the V2X communication technology corresponding to the base station 401 from an internal memory or an external server. The information about the V2X communication technology of the base station 401 corresponding to the base station 401 may include information about whether the area within the coverage of the base station 401 supports DSRC or C-V2X technology. The electronic device 200 may determine the base station 401 connected for cellular communication, and select a module from the DSRC module 210 and the C-V2X module 220 based on the V2X communication technology corresponding to the determined base station 401. The electronic device 200 may perform V2I communication with the infrastructure in the area included in the coverage of the base station 401 by using the selected V2X module.

[0053] In another example, according to an embodiment of the present disclosure, when a vehicle equipped with the electronic device 200 is traveling in an area where two different V2X technologies (i.e., DSRC and C-V2X) are simultaneously used, the electronic device 200 can switch to the V2X technology that provides better V2X communication performance by periodically searching for DSRC signals received via DSRC and C-V2X signals received via C-V2X.

[0054] According to an embodiment of the present disclosure, the processor 250 may select a module from the DSRC module 210 and the C-V2X module 220 by periodically comparing a DSRC signal received via the DSRC module 210 and a C-V2X signal received via the C-V2X module 220. The processor 250 may control the switch 240 to connect the antenna 230 to the DSRC module 210 or the C-V2X module 220 based on the comparison. The processor 250 may select the DSRC module 210 or the C-V2X module 220 based on comparison attributes such as a packet error rate (PER), a packet reception rate (PRR), a delay, and a strength of each of the DSRC signal and the C-V2X signal.

[0055] PER may represent the ratio of the number of packets lost at the receiver to the total number of packets queued at the sender, expressed as a percentage. PRR may represent the ratio of the number of packets received from a particular sender to the total number of packets queued at the sender, expressed as a percentage. A relationship of PRR=1-PER may be established. Latency may represent the time interval between the moment a sender application delivers an application layer packet (e.g., a basic safety message (BSM)) to a lower layer and the moment the application layer packet is received by the application layer at a receiver, expressed in milliseconds (msec).

[0056] According to an embodiment of the present disclosure, the processor 250 may control the switch 240 to perform diversity communication with one of the DSRC module 210 and the C-V2X module 220 by using a pair of sub-antennas included in the antenna 230 .

[0057] According to an embodiment of the present disclosure, the processor 250 may perform diversity V2X communication via one V2X communication technology by operating two sub-antennas of the pair of sub-antennas, while periodically searching for V2X signals by using another V2X communication technology.

[0058] For example, when the processor 250 searches for a V2X signal received via a second V2X communication technology instead of the first V2X communication technology currently in use, the processor 250 may operate one sub-antenna to maintain communication while searching for a V2X signal received via the second V2X communication technology by using another sub-antenna. The processor 250 may compare a first signal received via the first V2X communication technology with a second signal received via the second V2X communication technology, and select one of the first V2X communication technology and the second V2X communication technology based on the comparison result. The processor 250 may determine whether to maintain the first V2X communication technology or switch to the second V2X communication technology. The processor 250 may perform diversity V2X communication using the selected V2X communication technology based on the result of the determination.

[0059] For example, the processor 250 may perform V2X communication via DSRC technology by using a pair of sub-antennas. The processor 250 may control the switch 240 to receive a DSRC signal via the first sub-antenna in the pair of sub-antennas for a preset time period, and to receive a C-V2X signal via the second sub-antenna in the pair of sub-antennas. The processor 250 may determine whether to change from DSRC technology to C-V2X technology based on the result of comparing the DSRC signal and the C-V2X signal. When it is determined that the change is appropriate, the processor 250 may change the DSRC technology to the C-V2X technology, and perform V2X communication via the C-V2X technology by using the pair of sub-antennas.

[0060] As another example, according to an embodiment of the present disclosure, the processor 250 may select a V2X module from the DSRC module 210 and the C-V2X module 220 based on the surrounding environment information of the vehicle equipped with the electronic device 200, and control the switch 240 to connect the selected V2X module to the antenna 230. For example, the surrounding environment information of the vehicle may include a captured image of the surrounding environment of the vehicle or depth information obtained by sensing the depth of an object located near the vehicle. The processor 250 may obtain an image by capturing the surrounding environment of the vehicle using a camera, and identify an entity supporting V2I communication with the vehicle in the obtained image. For example, the entity supporting V2I communication with the vehicle may include facilities such as traffic lights or street lights installed on or around the road and base stations. Depending on the identified entity, the processor 250 may select a module from the DSRC module 210 or the C-V2X module 220 as a module supporting V2X communication. According to an embodiment of the present disclosure, the electronic device 200 may use conventional artificial intelligence (AI) technology to identify entities in the image.

[0061] Figure 44 is a diagram showing an example of a traffic light 430 supporting V2I communication communicating with a vehicle. A vehicle equipped with an electronic device 200 can obtain an image of the surrounding environment of the vehicle via a camera installed in the vehicle and determine the surrounding situation through image processing. The electronic device 200 can operate to recognize from the obtained image that the vehicle is approaching the traffic light 430, and preferentially receive a V2X signal (e.g., a C-V2X signal) from the traffic light 430.

[0062] For example, the electronic device 200 mounted to the vehicle may perform V2X communication by using the DSRC technology at the first location 410. The electronic device 200 may recognize that the vehicle is approaching a traffic light 430 by analyzing an image or signal obtained by a camera or a laser radar, and select the C-V2X module 220 based on the result of the recognition. The electronic device 200 may then perform V2X communication by using the C-V2X technology at the second location 420.

[0063] In addition, in order for the electronic device 200 to seamlessly provide information and services to the vehicle, stable V2X communication is required. Therefore, according to an embodiment of the present disclosure, when V2X communication via a given V2X communication technology is interrupted, the processor 250 can quickly switch to another V2X communication technology to continuously perform V2X communication.

[0064] The processor 250 may detect an interruption of wireless communication using the V2X communication technology in service. The processor 250 may periodically determine whether wireless communication via the V2X communication technology is performed normally. Based on the strength of the signal sent or received, determine whether the wireless communication is performed normally. Alternatively, the processor 250 may detect an interruption of wireless communication by receiving a data signal including information indicating an interruption of wireless communication. When communication via a given V2X communication technology is interrupted or terminated, the processor 250 may search for a signal by using another V2X communication technology. The processor 250 may determine whether it is appropriate to continuously perform V2X communication by switching to another V2X communication technology based on the found signal. For example, when the strength of the found signal is greater than or equal to a threshold, the processor 250 may determine that switching to another V2X communication technology is appropriate.

[0065] Alternatively, the processor 250 may determine whether to switch the V2X communication technology based on the location information of the vehicle or the information about the base station. For example, when it is determined that the area where the vehicle is located or the area within the coverage of the base station supports another V2X communication technology, the processor 250 may determine that it is appropriate to switch to the other V2X communication technology.

[0066] When the processor 250 determines that switching the V2X communication technology is desirable, the processor 250 may continue to perform V2X communication by switching to another V2X communication technology. On the other hand, when the processor 250 determines that switching the V2X communication technology is not desirable, the processor 250 may perform an operation for reactivating the session using the currently used V2X technology to maintain the use of the V2X communication technology for the interrupted communication, or wait for a preset time period until the interruption problem is resolved.

[0067] In addition, according to an embodiment of the present disclosure, the electronic device 200 may be composed of Figure 2 More components are shown to implement. Figure 5a According to an embodiment of the present disclosure, the electronic device 200 may further include a memory 560, a power supply 570, a global navigation satellite system (GNSS) module 580, a network access device (NAD) module 590, and antennas 531 and 533.

[0068] According to an embodiment of the present disclosure, the memory 560 may store instructions executed by the processor 250 to control the electronic device 200, an AI model, information processed by the processor 250, information received from an external server or another electronic device, etc. For example, the memory 560 may store at least one of information about V2X communication technology of one or more geographic areas and information about V2X communication technology of one or more base stations.

[0069] Although Figure 5a The electronic device 200 is shown to include a memory 560, but the embodiments of the present disclosure are not limited thereto, and the electronic device 200 may include a plurality of memories. For example, the memory 560 may include a double data rate synchronous dynamic random access memory (DDRSDRAM) and a flash memory such as an embedded multimedia card (eMMC).

[0070] According to an embodiment of the present disclosure, the power supply 570 may receive a constant power input and convert the power into a higher or lower voltage to be output, so as to provide different power levels to modules included in the electronic device 200 .

[0071] According to an embodiment of the present disclosure, the GNSS module 580 is a receiver module in the system that uses satellites to determine the position of the GNSS module 580. For example, in this case, the GNSS module 580 is connected to the Figure 4 The vehicles shown are located at the same location. The GNSS module 580 can receive information such as location information (e.g., longitude and latitude) and a map of the surrounding area from each satellite and help the vehicle's navigation system determine the vehicle's route to the destination. The GNSS module 580 can receive radio waves sent from each satellite and calculate the distance to the satellite to determine the vehicle's location.

[0072] According to an embodiment of the present disclosure, the NAD module 590 can connect the electronic device 200 to a network. The NAD module 590 may include a modem, an RF transceiver, and a front-end circuit for cellular communication (e.g., second generation (2G), third generation (3G), fourth generation (4G), fifth generation (5G), etc.).

[0092] Pairing of the Bluetooth transceiver 15 of the vehicle-based computing system 1 and the user mobile device 53 can be initiated by user input received via an input interface 52 (such as a button).

[0101] An advantage of the electronic device 200 according to certain embodiments of the present disclosure is that the best V2X technology can be selectively used by switching between the DSRC module 210 and the C-V2X module 220. In addition, because the antenna is shared between the DSRC module 210 and the C-V2X module 220, it is not necessary to provide an antenna for each V2X module separately, which reduces the space required for the antenna installed in the vehicle and the cost of the antenna. In addition, by reducing the number of antennas installed in the vehicle, not only the cost of the antenna can be reduced, but also additional costs such as the cost of the cable used to connect the antenna to the TCU and the labor cost associated with the antenna installation can be reduced.

[0102] In the following, reference will be made to Figures 7 to 12 The operating method of the electronic device 200 according to some embodiments of the present disclosure is described in more detail.

[0103] According to an embodiment of the present disclosure, the electronic device 200 may be installed in a vehicle to support wireless mobile communication of the vehicle.

[0105] According to an embodiment of the present disclosure, the electronic device 200 may select at least one module from the DSRC module 210 for performing wireless communication using the DSRC technology and the C-V2X module 220 for performing wireless communication using the C-V2X technology (operation S710).

[0106] According to an embodiment of the present disclosure, the electronic device 200 may select the best V2X communication technology according to various determination criteria, and then select a V2X module corresponding to the selected V2X communication technology. For example, the electronic device 200 may select the best V2X communication technology based on the location of the vehicle, the base station connected for cellular communication, the result of comparing the periodically found DSRC and C-V2X signals, or the surrounding environment information. Alternatively, the electronic device 200 may select the V2X communication technology corresponding to the user input.

[0107] For example, the electronic device 200 may obtain the location information of the vehicle equipped with the electronic device 200, and based on the obtained location information, select a module from the DSRC module 210 and the C-V2X module 220 as a module supporting the V2X communication technology corresponding to the current location of the vehicle. The electronic device 200 also obtains information about the V2X communication technology corresponding to the location of the vehicle, and based on the information about the V2X communication technology corresponding to the location of the vehicle and the location information of the vehicle, selects a module from the DSRC module 210 and the C-V2X module 220 as a module supporting the V2X communication technology corresponding to the current location of the vehicle.

Fig. 9 The method of selecting V2X communication technology based on base station information is described in more detail.

[0109] As another example, the electronic device 200 may select a module from the DSRC module 210 and the C-V2X module 220 as a module supporting the best V2X communication technology by periodically comparing the DSRC signal received via the DSRC module 210 and the C-V2X signal received via the C-V2X module 220. The electronic device 200 may select one of the DSRC module 210 and the C-V2X module 220 by comparing at least one of the PER, PRR, delay, or strength of each of the DSRC signal and the C-V2X signal with each other.

The electronic device 200 may obtain an image by capturing the surrounding environment of the vehicle, and identify entities supporting V2I communication with the vehicle in the obtained image. For example, entities supporting V2I communication with the vehicle may include facilities such as traffic lights or street lights installed on or around the road on which the vehicle is traveling, and base stations. The electronic device 200 may select a module from the DSRC module 210 and the C-V2X module 220 as a module that supports the V2X communication technology corresponding to the identified entity. Reference will be made to Fig.12 A method for selecting a V2X communication technology based on surrounding environment information of a vehicle is described in more detail.

When the electronic device 200 determines that switching the V2X communication technology is desirable, the electronic device 200 may select a V2X module that supports another V2X communication technology. On the other hand, when the electronic device 200 determines that switching the V2X communication technology is not desirable, the electronic device 200 may select a V2X module that supports the currently interrupted V2X communication technology. The electronic device 200 may perform an operation for reactivating a session using the currently used V2X technology to maintain the use of the V2X communication technology for the interrupted communication, or wait for a preset time period until the interruption problem is resolved.

[0114] According to an embodiment of the present disclosure, the electronic device 200 may control the switch 240 to connect the selected at least one module to the antenna (operation S720).

[0119] The electronic device 200 may obtain the location information of the vehicle at a preset periodic time period or at a preset distance interval. For example, the electronic device 200 may obtain the location information of the vehicle from a server, a base station, an infrastructure, or another electronic device installed in another vehicle that communicates with the electronic device 200. Alternatively, the electronic device 200 may obtain the location information of the vehicle from a navigation system installed in the vehicle. Alternatively, the electronic device 200 may obtain the location information of the vehicle by calculating the location of the vehicle based on a GPS signal from a GNSS module 580 included in the electronic device 200.

When the vehicle starts and starts to travel, the electronic device 200 may obtain information about a base station that performs cellular communication with the electronic device 200.

[0127] The information about the base station may include location information of the base station, identification information of the base station, identification information of adjacent base stations, and the like.

[0128] The electronic device 200 may periodically obtain information about the base station at a preset time period or at a preset distance interval. For example, the electronic device 200 may directly obtain information about the base station connected to the electronic device 200 from the base station, or obtain information about the base station stored in an internal module such as a memory or NAD module.

[0129] According to an embodiment of the present disclosure, the electronic device 200 may select at least one module from among the DSRC module 210 and the C-V2X module 220 based on information about a base station (operation S910).

[0134] Fig.10 1 is a flowchart of a method for switching V2X communication technology based on a result of comparing a DSRC signal and a C-V2X signal, performed by an electronic device 200 according to an embodiment of the present disclosure. According to an embodiment of the present disclosure, when a vehicle equipped with the electronic device 200 is traveling in an area where two different V2X technologies (i.e., DSRC and C-V2X) are used simultaneously, the electronic device 200 can switch to a V2X technology that provides better V2X communication performance by periodically searching for a DSRC signal received via DSRC or a C-V2X signal received via C-V2X.

[0135] According to an embodiment of the present disclosure, the electronic device 200 may obtain a DSRC signal and a C-V2X signal (operation S1005).

[0136] The electronic device 200 can normally perform diversity V2X communication via the first V2X communication technology by operating two sub-antennas. The electronic device 200 maintains the first V2X communication technology for one of the sub-antennas while periodically searching for a V2X signal of the second V2X communication technology by using the other sub-antenna.

[0137] According to an embodiment of the present disclosure, the electronic device 200 may select at least one module from the DSRC module 210 and the C-V2X module 220 based on the result of comparing the DSRC signal and the C-V2X signal (operation S1010).

The electronic device 200 may control the switch 240 by sending a control signal generated in the processor 250 to the switch 240 to connect the selected module to the antenna.

[0139] According to an embodiment of the present disclosure, the electronic device 200 may perform V2X communication via the selected at least one module (operation S1030). The electronic device 200 may perform diversity transmission and diversity reception of V2X signals by simultaneously using a pair of sub-antennas included in the antenna.

[0140] According to an embodiment of the present disclosure, by periodically searching for signals received via a second V2X communication technology while communicating with a first V2X communication technology, when the communication quality changes, the electronic device 200 can continuously and seamlessly perform V2X communication by switching to a V2X communication technology that is expected to achieve higher performance.

[0141] Fig.11 1 is a flowchart of a method for switching V2X communication technology by periodically searching for DSRC signals and C-V2X signals, performed by the electronic device 200 according to an embodiment of the present disclosure.

[0142] According to an embodiment of the present disclosure, the electronic device 200 may perform V2X communication via a first technology selected from any one of the DSRC technology and the C-V2X technology (operation S1110). For convenience of description, the unselected technology is referred to as the second technology hereinafter. The electronic device 200 may perform diversity V2X communication by operating two sub-antennas. The electronic device 200 may determine whether to change the communication technology for better communication performance by periodically searching for signals received via another technology.

[0143] The electronic device 200 may receive a first signal by maintaining V2X communication using a first technology for one of the pair of sub-antennas (operation S1121). The electronic device 200 may control the switch 240 to periodically search for a V2X signal received via a second technology for the other sub-antenna. The electronic device 200 may receive a second signal by performing V2X communication with the other of the pair of sub-antennas via the second technology (operation S1123).

[0144] According to an embodiment of the present disclosure, the electronic device 200 may compare the first signal and the second signal (operation S1130). The electronic device 200 may determine whether it is necessary to change the V2X communication technology by comparing at least one of the PER, PRR, delay or strength of each of the first and second signals with each other (operation S1140).

[0145] For example, when the PER of the first signal is greater than the PER of the second signal, the electronic device 200 may determine that the V2X communication technology needs to be changed from the first technology to the second technology. Conversely, when the PER of the first signal is less than or equal to the PER of the second signal, the electronic device 200 may determine that the first technology should be maintained. Alternatively, when the PRR of the first signal is less than the PRR of the second signal, the electronic device 200 may determine that the V2X communication technology needs to be changed from the first technology to the second technology. Conversely, when the PRR of the first signal is greater than or equal to the PRR of the second signal, the electronic device 200 may determine that the first technology should be maintained. When the delay of the first signal is longer than the delay of the second signal, the electronic device 200 may determine that the V2X communication technology needs to be changed from the first technology to the second technology. Conversely, when the delay of the first signal is shorter than or equal to the delay of the second signal, the electronic device 200 may determine that the first technology should be maintained. Alternatively, when the amplitude of the first signal is less than the amplitude of the second signal, the electronic device 200 may determine that the V2X communication technology needs to be changed from the first technology to the second technology. In contrast, when the amplitude of the first signal is greater than or equal to the amplitude of the second signal, the electronic device 200 may determine that the first technique should be maintained.

[0146] According to an embodiment of the present disclosure, when it is determined that there is no need to change the V2X communication technology, the electronic device 200 may return to operation S1110 to continuously perform V2X communication using the first technology. On the other hand, when it is determined that it is necessary to change the V2X communication technology, the electronic device 200 may connect the V2X module supporting the second technology to the antenna by controlling the switch 240, and perform V2X communication via the V2X module supporting the second technology (operation S1150).

[0147] Fig.12 is a flowchart of a method for switching V2X communication technology based on surrounding environment information, performed by an electronic device 200 according to an embodiment of the present disclosure.

[0148] According to an embodiment of the present disclosure, the electronic device 200 may obtain the surrounding environment information of the vehicle (operation S1205). The electronic device 200 may periodically obtain the surrounding environment information when the vehicle is traveling.

[0149] For example, the vehicle's surrounding environment information may include at least one of a captured image of the vehicle's surrounding environment, depth information obtained by sensing the depth of an object located near the vehicle, or information received from other surrounding vehicles.

[0150] The electronic device 200 can obtain captured images of the surrounding environment of the vehicle at preset time periods or preset distance intervals. For example, the electronic device 200 can obtain images including buildings, mountains, other vehicles, pedestrians, lanes, headlights, and street trees located within a certain distance from the vehicle.

[0151] According to an embodiment of the present disclosure, the electronic device 200 may select at least one module from the DSRC module 210 and the C-V2X module 220 based on surrounding environment information of the vehicle (operation S1210).

[0152] The electronic device 200 may identify an entity supporting V2I communication with the vehicle in an image of the surrounding environment of the vehicle, and select a module from the DSRC module 210 and the C-V2X module 220 as a module supporting the V2X communication technology corresponding to the identified entity. According to an embodiment of the present disclosure, the electronic device 200 may use AI to identify an entity in an image.

[0153] According to various embodiments of the present disclosure, the electronic device 200 may use AI to support wireless mobile communication of the vehicle. For example, as described above, AI may be used to analyze surrounding environment information and prompt changes in communication technology.

[0154] According to the present disclosure, AI-related functions can be operated via a processor and a memory. The processor can be configured as one or more processors. In this case, the one or more processors can be a general-purpose processor (such as a CPU, an application processor (AP), or a digital signal processor (DSP)), a dedicated graphics processor (such as a graphics processor (GPU) or a visual processing unit (VPU)), or a dedicated AI processor (such as a neural processing unit (NPU)). One or more processors can control the input data to be processed according to predefined operating rules or an AI model stored in a memory. Alternatively, when one or more processors are dedicated AI processors, the dedicated AI processor can be designed with a hardware structure dedicated to processing a specific AI model.

[0155] The predefined operating rules or AI models can be created via a training process. In this case, creation via a training process means creating predefined operating rules or AI models that are set to perform the desired features (or purposes) by training the basic AI model based on a large amount of training data via a learning algorithm. The training process can be performed by the device executing the AI ​​itself, or via a separate server and / or system. Examples of learning algorithms may include, but are not limited to, supervised learning, unsupervised learning, semi-supervised learning, and reinforcement learning.

[0156] The AI ​​model may include multiple neural network layers. Each layer in the neural network layer has multiple weight values, and the neural network calculation may be performed via calculations between the calculation results of the previous layer and the multiple weight values. The multiple weight values ​​assigned to each layer in the neural network layer may be optimized based on the results of training the AI ​​model. For example, multiple weight values ​​may be modified to reduce or minimize the loss or cost value obtained by the AI ​​model during training. The artificial neural network may include a deep neural network (DNN), and may be, for example, a convolutional neural network (CNN), a DNN, an RNN, a restricted Boltzmann machine (RBM), a deep belief network (DBN), a bidirectional recurrent DNN neural network (BRDNN), or a deep Q network (DQN), but is not limited thereto.

[0157] According to an embodiment of the present disclosure, the electronic device 200 may control the switch 240 to connect the selected at least one module to the antenna (operation S1220). The electronic device 200 may control the switch 240 by sending a control signal generated in the processor 250 to the switch 240 to connect the selected module to the antenna.

[0158] According to an embodiment of the present disclosure, the electronic device 200 may perform V2X communication via the selected at least one module (operation S1230). The electronic device 200 may perform diversity transmission and diversity reception of V2X signals by simultaneously using a pair of sub-antennas included in the antenna.

[0159] According to an embodiment of the present disclosure, by continuously monitoring the surrounding environment information of the vehicle, when the supported V2X communication technology changes according to the change of the surrounding environment of the vehicle, the electronic device 200 can continuously perform V2X communication by switching to the supported V2X communication technology based on the change of the surrounding environment of the vehicle.

[0160] Fig.13 is a view illustrating an example in which the device 1000 and the server 2000 interactively work together to learn and recognize data according to an embodiment of the present disclosure.

[0161] According to an embodiment of the present disclosure, the electronic device 200 or the vehicle-based computing system 1 can interact with the server 2000 to support wireless mobile communication by using AI. For example, the electronic device 200 or the vehicle-based computing system 1 can use AI for analyzing surrounding environment information to change V2X communication technology. Fig.13 The device 1000 may correspond to the electronic device 200 or the processor 250 of the electronic device 200 , or the vehicle-based computing system 1 or the CPU 3 of the vehicle-based computing system 1 .

[0162] refer to Fig.13 , the server 2000 may learn criteria for determining a situation and / or selecting a V2X communication technology, and the device 1000 may determine a situation based on a result learned by the server 2000.

[0163] According to an embodiment of the present disclosure, the data learner 2300 included in the server 2000 may learn a criterion for determining a situation and / or selecting a V2X communication technology. The data learner 2300 may learn a criterion about which data will be used to determine a situation or select a V2X communication technology and how to determine a situation or select a V2X communication technology by using data. The data learner 2300 may acquire data for training and learn a criterion for determining a situation and / or selecting a V2X communication technology by applying the acquired data to a data recognition model.

[0164] According to an embodiment of the present disclosure, the data identifier 1320 included in the device 1000 may determine a situation or select a V2X communication technology based on the data. The data identifier 1320 may identify a situation from the data by using a trained data recognition model. The data identifier 1320 may acquire data according to a learned preset standard, and determine a situation or select a V2X communication technology based on the data by using a data recognition model that takes the acquired data as an input value. In addition, the result value output by the data recognition model that takes the acquired data as an input value may be used to modify and refine the data recognition model.

[0165] At least one of the data learner 2300 and the data identifier 1320 may be manufactured in the form of at least one hardware chip that can be installed in an electronic device. For example, at least one of the data learner 2300 and the data identifier 1320 may be manufactured in the form of a dedicated hardware chip for AI, or as part of an existing general-purpose processor (e.g., CPU or AP) or a dedicated graphics processor (e.g., GPU), and may be installed in various electronic devices as described above.

[0166] The data learner 2300 and the data identifier 1320 can be connected to each other via wired or wireless communication, so that the model information generated by the data learner 2300 can be provided to the data identifier 1320, and the data input to the data identifier 1320 can be provided to the data learner 2300 as additional training data.

[0167] In addition, at least one of the data learner 2300 and the data identifier 1320 may be implemented as a software module. When at least one of the data learner 2300 and the data identifier 1320 is implemented as a software module (or a program module including instructions), the software module may be stored in a non-transitory computer-readable recording medium. In addition, in this case, at least one software module may be provided by the OS or the application. Alternatively, some of the at least one software module may be provided by the OS, while the rest may be provided by the application.

[0168] According to an embodiment of the present disclosure, the data learner 2300 may include a data acquirer 2310 , a preprocessor 2320 , a training data selector 2330 , a model trainer 2340 , and a model evaluator 2350 .

[0169] The data acquirer 2310 may acquire data required to determine a situation and / or select a V2X communication technology.

[0170] For example, the data acquirer 2310 can receive a still image or a video. A video can be composed of multiple images (or frames). For example, the data acquirer 2310 can receive a video via an external camera (e.g., a closed-circuit television or a black box camera). In this case, the camera can include one or more image sensors (e.g., a front sensor or a rear sensor), a lens, an image signal processor (ISP), or a flash (e.g., an LED or a xenon lamp). As another example, the data acquirer 2310 can receive a video stored in an external memory from an external memory.

[0171] The preprocessor 2320 may preprocess the acquired data so that the acquired data may be used for situation determination and / or selection of V2X communication technology in training. The preprocessor 2320 may process the data acquired for training into a preset format so that the model trainer 2340 described later may use the acquired data.

[0172] The training data selector 2330 may select data required for training from the preprocessed data. The selected data may be provided to the model trainer 2340. The training data selector 2330 may select data required for training from the preprocessed data according to a preset standard. In addition, the training data selector 2330 may select data according to a preset standard learned by the model trainer 2340 described later.

[0173] The model trainer 2340 may learn criteria on how to determine a situation or select which V2X communication technology based on training data. In addition, the model trainer 2340 may learn criteria on which training data will be used to determine a situation and / or select a V2X communication technology.

[0174] For example, the model trainer 2340 may learn a criterion for identifying a certain entity in an image by learning an image. As another example, by learning vehicle driving information, the model trainer 2340 may learn a criterion for selecting an optimal V2X communication technology based on the vehicle's location information, information about a base station connected for cellular communication, a result of comparing periodically found DSRC and C-V2X signals, or surrounding environment information.

[0175] In addition, the model trainer 2340 may use the training data to train a data recognition model for determining a situation and / or selecting a V2X communication technology. In this case, the data recognition model may be a previously generated model. For example, the data recognition model may be a model previously generated by receiving basic training data (e.g., sample images, information about the best V2X communication technology determined according to the vehicle position, etc.).

[0176] The data recognition model can be established by considering the application field of the data recognition model, the learning target, or the computer performance of the device running the data recognition model. For example, the data recognition model can be a model based on a neural network. Models such as convolutional neural networks (CNNs), deep neural networks (DNNs), recurrent neural networks (RNNs), and bidirectional recurrent DNNs (BRDNNs) can be used as data recognition models, but the data recognition model is not limited thereto.

[0177] For example, the model trainer 2340 may train a data recognition model for recognizing an object included in an image by using a previously acquired image. As another example, the model trainer 2340 may train a data recognition model by using vehicle driving information to select an optimal V2X communication technology according to the location of the vehicle.

[0178] The model evaluator 2350 may input evaluation data to the data recognition model, and when the recognition result obtained from the evaluation data does not meet the preset standard, cause the model trainer 2340 to train the data recognition model again. In this case, the evaluation data may be preset data for evaluating the data recognition model. For example, the evaluation data may include data related to the accuracy of the entity recognized in the image or data obtained by comparing periodically found DSRC and C-V2X signals with each other.

[0179] For example, when the number or ratio of evaluation data with inaccurate recognition results among the recognition results output from the trained data recognition model for the evaluation data exceeds a preset threshold, the model evaluator 2350 may evaluate that the preset standard is not met. For example, when the preset standard is defined as a ratio of 2%, and when the trained data recognition model outputs an erroneous recognition result with respect to more than 20 evaluation data out of a total of 1000 evaluation data, the model evaluator 2350 may evaluate the trained data recognition model as inappropriate.

[0180] At least one of the data acquirer 2310, the preprocessor 2320, the training data selector 2330, the model trainer 2340, or the model evaluator 2350 in the data learner 2300 may be manufactured in the form of at least one hardware chip installed in an electronic device. For example, at least one of the data acquirer 2310, the preprocessor 2320, the training data selector 2330, the model trainer 2340, or the model evaluator 2350 may be manufactured in the form of a dedicated hardware chip for AI, or as part of an existing general-purpose processor (e.g., a CPU or AP) or a dedicated graphics processor (e.g., a GPU), and may be installed in various electronic devices as described above.

[0181] In addition, at least one of the data acquirer 2310, the preprocessor 2320, the training data selector 2330, the model trainer 2340, or the model evaluator 2350 may be implemented as a software module. When at least one of the data acquirer 2310, the preprocessor 2320, the training data selector 2330, the model trainer 2340, or the model evaluator 2350 is implemented as a software module (or a program module including instructions), the software module may be stored in a non-transitory computer-readable recording medium. In addition, in this case, at least one software module may be provided by the OS or the application.

[0185] The recognition result provider 1320-4 of the device 1000 can determine the situation and / or select the V2X communication technology by applying the data selected by the recognition data selector 1320-3 to the data recognition model generated by the server 2000. The recognition result provider 1320-4 can provide the recognition result according to the purpose of data recognition. The recognition result provider 1320-4 can apply the data selected by the recognition data selector 1320-3 to the data recognition model by using the selected data as an input value. In addition, the recognition result can be determined by the data recognition model.

[0186] For example, the recognition result provider 1320-4 may provide a result of recognizing an object included in a still image or a video. The recognition result provider 1320-4 may obtain an image of the surrounding environment and determine the surrounding environment situation through image processing. The recognition result provider 1320-4 may obtain a captured image of the surrounding environment of the vehicle and identify an entity supporting V2I communication with the vehicle in the obtained image.

[0188] The model refiner 1320-5 can modify and refine the data recognition model based on the evaluation of the recognition result provided by the recognition result provider 1320-4. For example, the model refiner 1320-5 can cause the model trainer 2340 to modify and refine the data recognition model by providing the recognition result from the recognition result provider 1320-4 to the model trainer 2340.

[0189] At least one of the data acquirer 1320-1, the preprocessor 1320-2, the recognition data selector 1320-3, the recognition result provider 1320-4, or the model refiner 1320-5 can be manufactured in the form of at least one hardware chip that can be installed in an electronic device.
