In this context, vehicle-mounted games are increasingly favored by users. When playing vehicle-mounted games, users can connect game controllers to vehicle infotainment systems through star flash technology.
[0004] However, when connecting game controllers and vehicle infotainment systems using star flash technology, if the Bluetooth (BT) function and / or the wireless fidelity (WiFi) function in the vehicle are used at the same time, it may cause certain interference to the star flash connection, thereby affecting the user's game experience in the game. Correspondingly, the star flash connection may also cause certain interference to the Bluetooth function and / or the WiFi function, resulting in latency or lag when the vehicle transmits data using Bluetooth connection or WiFi connection, or even disconnection.

[0060] The technical solutions in the embodiments of the present application will be described below with reference to the drawings.
[0061] FIG. 1 is a functional schematic diagram of a vehicle 100 according to an embodiment of the present application.
[0062] The vehicle 100 can include various subsystems, such as a perception system 120, a computing platform 130, and an antenna system 140. Alternatively, the vehicle 100 can include more or fewer subsystems, and each subsystem can include one or more components. In addition, each subsystem and component of the vehicle 100 can be interconnected by wired or wireless means.
[0063] The perception system 120 can include several sensors for sensing information about the environment surrounding the vehicle 100. For example, the perception system 120 can include a positioning system, which can be a global positioning system (GPS), a Beidou system, or other positioning systems. The perception system 120 can include one or more of an inertial measurement unit (IMU), a lidar, a millimeter wave radar, an ultrasonic radar, and a camera.
[0064] Some or all functions of the vehicle 100 can be controlled by the computing platform 130. The computing platform 130 can include processors 131-13n (n is a positive integer), which are circuits having a processing capability of signals. In one implementation, the processor can be a circuit having an instruction reading and running capability, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP), etc. In another implementation, the processor can implement certain functions through a logic relationship of a hardware circuit, which is fixed or reconfigurable, such as an application-specific integrated circuit (ASIC) or a programmable logic device (PLD) implemented hardware circuit, such as an FPGA. In a reconfigurable hardware circuit, the processor loads a configuration document to implement the hardware circuit configuration, which can be understood as the processor loading instructions to implement the functions of the above part or all units. In addition, the processor can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc. In addition, the computing platform 130 can also include a memory for storing instructions, and some or all of the processors 131-13n can call the instructions in the memory to implement corresponding functions.
[0065] The computing platform 130 can control the functions of the vehicle 100 based on the input received from various subsystems (e.g., the perception system 120). In some embodiments, the computing platform 130 can be used to provide control over many aspects of the vehicle 100 and its subsystems.
[0066] The antenna system 140 can function to receive and transmit radio signals to ensure proper functioning of various wireless functions within the vehicle and to ensure proper communication between the vehicle and external devices.
[0067] Optionally, the above components are only an example, and in actual applications, components in each module can be added or deleted according to actual needs.
[0068] The vehicle 100 in the present application can include: a road vehicle, a water vehicle, an air vehicle, an industrial device, an agricultural device, or an entertainment device, etc. For example, the vehicle 100 can be a vehicle (such as a commercial vehicle, a passenger vehicle, a motorcycle, a flying vehicle, a train, etc.), an industrial vehicle (such as a forklift, a trailer, a tractor, etc.), an engineering vehicle (such as an excavator, a bulldozer, a crane, etc.), an agricultural device (such as a mower, a harvester, etc.), a recreational device, a toy vehicle, etc. The type of the vehicle is not limited in the embodiments of the present application.
[0069] The following takes the vehicle 100 as an example of an intelligent vehicle to explain the technical problems to be solved and the technical solutions adopted in the present application.
[0070] With the wide use of intelligent vehicles in daily life, users expect that the intelligent vehicles and related devices can bring more comfortable intelligent experience. In this context, vehicle-mounted games are increasingly favored by users. In the process of vehicle-mounted game experience, users can connect the game handle with the vehicle machine through wireless connection.
[0071] Currently, the game handle can be connected with the vehicle machine by using Bluetooth or 2.4G WiFi technology. However, the game handle connected with the vehicle machine by using Bluetooth technology has a delay problem, which causes the user to have a phenomenon of operation lag in the game process, thereby affecting the user's game experience. Although the 2.4G WiFi connection technology can achieve relatively good connection stability, the 2.4G WiFi connection technology must be equipped with a receiver, and can only realize a one-to-one working mode (i.e., the vehicle machine can only communicate with one game handle), which also brings many inconveniences to the user. To solve the above problems, the game handle and the vehicle machine can be connected by using star flash technology, which can reduce the time delay of the game handle in data transmission, realize a one-to-many working mode, and thus enable the user to obtain a more immersive game experience in the game.
[0072] However, when the gamepad and the vehicle are connected by using the star flash technology, if the Bluetooth function and / or the WiFi function in the vehicle are used at the same time, the star flash connection may be interfered, and the user's game experience in the game is affected. Correspondingly, the star flash connection may also interfere with the Bluetooth function and / or the WiFi function, causing delay or lag when the vehicle transmits data by using the Bluetooth connection and / or the WiFi connection, or even disconnection.
[0073] The embodiment of the present application provides an antenna system, an antenna box, a communication method and a vehicle. The antenna system integrates multiple communication technologies. When part or all of the communication technologies are used at the same time, the interference between the antennas corresponding to the communication technologies can be reduced. When the antenna system is applied to the vehicle, the vehicle and the external device can realize high-quality data transmission.
[0074] In one embodiment, an antenna system is provided, which comprises a first antenna, a second antenna, a third antenna, a first partition, a second partition and a metal base. The first antenna, the second antenna and the third antenna are arranged on the metal base in sequence. The first antenna is used for communication based on a first communication technology. The second antenna is used for communication based on the first communication technology and a second communication technology. The third antenna is used for communication based on a third communication technology. The first partition is used to improve the isolation degree of the first antenna and the second antenna. The second partition is arranged between the second antenna and the third antenna, and is used to improve the isolation degree of the second antenna and the third antenna.
[0075] Exemplarily, the first communication technology can be a wireless fidelity technology, the second communication technology can be a Bluetooth technology, and the third communication technology can be a star flash technology.
[0076] Optionally, the first antenna, the second antenna and the third antenna can be arranged in a long strip shape or a circular shape. Further optionally, the first antenna, the second antenna and the third antenna can be planar inverted F antenna (pifa) antennas. The pifa antenna adopts a planar radiation unit as a radiator and a large metal ground as a reflecting surface, has the advantages of compact structure, stable performance and easy integration, and improves impedance matching and antenna efficiency under the condition that the height of the pifa antenna is constant.
[0077] Optionally, the metal base can be made of stainless steel material. Since the stainless steel material has good corrosion resistance and high mechanical strength, the service life of the metal base can be improved. The metal base can function as a metal ground of the antenna system and can play a good conductive role. The metal base can also support other components in the antenna system. Further optionally, the metal base can be replaced by a base made of other metal materials and having the same functions.
[0078] Optionally, the first partition plate and / or the second partition plate is composed of polycarbonate and acrylonitrile-butadiene-styrene copolymer, so that the first partition plate and / or the second partition plate can adapt to the external environmental temperature of the antenna system, and the manufacturing cost of the antenna system can be reduced.
[0079] Optionally, the surface of the first partition plate and / or the second partition plate can be etched into a wavy shape or a zigzag shape.
[0080] Optionally, the third antenna can also be used for communication based on the second communication technology.
[0081] It should be noted that the first partition plate for improving the isolation of the first antenna and the second antenna can be understood as that the isolation of the first antenna and the second antenna after adding the first partition plate is greater than the isolation of the first antenna and the second antenna without adding the first partition plate, and correspondingly, the second partition plate for improving the isolation of the second antenna and the third antenna can be understood as that the isolation of the second antenna and the third antenna after adding the second partition plate is greater than the isolation of the second antenna and the third antenna without adding the second partition plate.
[0082] It should be further noted that since the second antenna can perform communication based on the first communication technology and the second communication technology, when the first communication technology and the second communication technology are at the same frequency, the second antenna can support the application of one communication technology, or when the first communication technology and the second communication technology are at different frequencies, the second antenna can simultaneously support the application of two communication technologies.
[0083] It should be further noted that when the third communication technology is star flash technology, the star flash connection can also be used as a Bluetooth connection, at this time, the star flash connection and the Bluetooth connection can be at different frequencies, that is, the third antenna can perform star flash communication or Bluetooth communication.
[0084] In the embodiment of the application, an antenna system is designed, which integrates multiple communication technologies. When part or all of the above communication technologies are used at the same time, the interference between the antennas corresponding to each communication technology can be reduced. When the antenna system is applied to a vehicle, high-quality data transmission between the vehicle and external equipment can be achieved. When the external equipment is a gamepad, the antenna system can establish a communication connection with the gamepad, so that users can obtain a more immersive game experience in the game.
[0085] In a possible implementation manner, the first antenna is arranged along a first direction, the second antenna is arranged along a second direction, and the third antenna is arranged along a third direction. The second direction corresponds to the length direction of the metal base. The included angle between the first direction and the second direction is a first preset value, and the included angle between the third direction and the second direction is a second preset value.
[0086] Optionally, the first preset value and the second preset value can be any angle, and the first preset value and the second preset value can be the same or different. Further optionally, the first preset value is greater than or equal to 40 degrees and less than or equal to 50 degrees, and the second preset value is greater than or equal to 10 degrees and less than or equal to 20 degrees.
[0087] Optionally, in this implementation, the first antenna, the second antenna and the third antenna can be arranged in a strip shape, and the first antenna arranged along the first direction can be understood as that the long side of the first antenna is arranged along the first direction, and similarly, the second antenna and the third antenna can also be understood in the same way.
[0088] In the embodiment of the application, by setting the placement angles of the first antenna, the second antenna and the third antenna, the isolation between the antennas can be further optimized, so that when the game handle and the antenna system establish a communication connection, the game handle can realize high-quality data transmission with the antenna system.
[0089] In a possible implementation, the antenna system further includes a reflecting plate; the reflecting plate is connected with the metal base, and the included angle between the reflecting plate and the metal base is a third preset value; the first partition plate is connected with the metal base and the reflecting plate, and the second partition plate is connected with the metal base and the reflecting plate.
[0090] For example, the third preset value is 70 degrees.
[0091] In the embodiment of the application, the reflecting plate is arranged in the antenna system, and since the reflecting plate is connected with the metal base, the first partition plate and the second partition plate, the reflecting plate can fix the antenna system, so that the antenna system is not easily damaged and the service life of the antenna system can be prolonged.
[0092] In a possible implementation, the first partition plate includes M holes or M openings, and the M holes or M openings are used to improve the isolation between the first antenna and the second antenna, and M is a positive integer; the second partition plate includes N holes or N openings, and the N holes or N openings are used to improve the isolation between the second antenna and the third antenna, and N is a positive integer.
[0093] For example, M = N = 5.
[0094] In the embodiment of the application, by arranging a plurality of holes or openings on the first partition plate and / or the second partition plate, the isolation between the antennas can be further optimized, so that when the game handle and the antenna system establish a connection based on the third communication technology, and the communication connection based on the first communication technology and the second communication technology in the antenna system is used at the same time, the interference between the antennas can be further reduced.
[0095] In a possible implementation, the antenna system can be applied to a vehicle, and a plurality of through holes or a plurality of grooves are further arranged on the metal base, and the plurality of cables connected to the first antenna, the second antenna and the third antenna are connected to the vehicle machine through the plurality of through holes or the plurality of grooves.
[0096] Optionally, the plurality of cables can be radio frequency cables for transmitting radio frequency signals, and the plurality of cables can be connected to the first antenna, the second antenna and the third antenna through welding technology.
[0097] For example, three through holes are arranged on the metal base, which are a first through hole, a second through hole and a third through hole, the first radio frequency cable welded to the first antenna can be connected to the vehicle machine through the first through hole, the second radio frequency cable welded to the second antenna can be connected to the vehicle machine through the second through hole, and the third radio frequency cable welded to the third antenna can be connected to the vehicle machine through the third through hole.
[0098] It should be noted that the relationship between the radio frequency cable and the through hole is only an example, and a person skilled in the art can reasonably change the corresponding relationship between the radio frequency cable and the through hole of the antenna according to actual needs.
[0099] In the embodiment of the application, when the antenna system is applied to a vehicle, the plurality of cables connected to the first antenna, the second antenna and the third antenna can be connected to the vehicle machine through the plurality of through holes or the plurality of grooves, so as to facilitate the antennas to transmit radio frequency signals to the vehicle machine through the plurality of cables.
[0100] In a possible implementation, a plurality of nested nuts are further arranged on the metal base, and the plurality of nested nuts are used to accommodate a plurality of screws, so that the metal base is connected to the shell of the vehicle machine.
[0101] Optionally, the height of the plurality of nested nuts can be close to the height of each antenna; and a certain interval (for example, an interval of 1 mm) can be left between the metal base and the shell of the vehicle machine.
[0102] It should be noted that the parameters and arrangement of the nested nuts are only an example, and a person skilled in the art can reasonably change the parameters and arrangement of the nested nuts according to actual needs.
[0103] In the embodiment of the application, the antenna system can be fixed on the shell of the vehicle machine through the plurality of nested nuts and the plurality of screws, so as to ensure that the vehicle can communicate with external equipment through the antenna system.
[0104] The structure of the antenna system will be described in detail below with reference to FIGS. 2 to 6.
[0105] As shown in FIG. 2, the antenna system can include: an antenna 1, an antenna 2, an antenna 3, a first partition, a second partition, a reflecting plate, and three radio frequency cables. The antenna 1 can correspond to a first antenna, the antenna 3 can correspond to a second antenna, and the antenna 2 can correspond to a third antenna.
[0106] The antenna 1, the antenna 3, and the antenna 2 are sequentially arranged on the metal base. The antenna 1 is used for wireless fidelity communication. The antenna 3 is used for Bluetooth and wireless fidelity communication. The antenna 2 is used for star flash communication. That is, the antenna 3 is shared by Bluetooth and wireless fidelity functions. The antenna 1 is used only for wireless fidelity function. The antenna 2 is used only for star flash function. The antenna 3 is arranged between the antenna 1 and the antenna 2, so that the Bluetooth function meets the power spectral density (PSD), the interference of Bluetooth communication on other antennas can be reduced, and the reliability of Bluetooth communication can be improved. The antenna 2 is arranged at the rightmost side of the metal base, so that the isolation of the antenna 2 can achieve a good effect, that is, the influence of the antenna 1 and the antenna 3 on the antenna 2 is relatively small. The antenna 1 can be arranged along a first direction. The antenna 3 can be arranged along a second direction. The antenna 2 can be arranged along a third direction. The second direction corresponds to the length direction of the metal base. The angle between the first direction and the second direction can be 45 degrees with a deviation of ±5 degrees. The angle between the third direction and the second direction is 15 degrees with a deviation of ±5 degrees. The principle of the above-mentioned angle arrangement of the antenna is that the angle of the antenna arrangement position follows the polarization orthogonal principle. Specifically, the polarization isolation of the antenna refers to the interference degree of one polarization signal with another polarization signal in the transmission process. For a wireless communication system, the polarization isolation is an important performance parameter, which directly affects the communication quality and reliability. In the same frequency band, if the polarization directions of two antennas are the same, the interference between them will be more serious, which reduces the communication quality. On the contrary, if the polarization directions of the two antennas are different, the interference between them will be small, and the communication quality can be guaranteed. If the angle between the two antennas is small, the interference between them will be more serious, which affects the stability of the polarization isolation. Therefore, when installing and debugging the antenna, attention should be paid to the angle selection of the antenna to reduce the interference as much as possible. The angle between the first direction and the second direction is set to 45 degrees with a deviation of ±5 degrees, and the angle between the third direction and the second direction is set to 15 degrees with a deviation of ±5 degrees, which can meet the above-mentioned requirements.
[0107] For example, the working frequency bands of the antennas in the antenna system in different scenarios can be shown in Table 1.
[0108] Table 1
[0109] It should be noted that the internal structure of the antenna system and the application scenario of the antenna system shown in FIG. 2 and Table 1 are only exemplary, and those skilled in the art can change the internal structure of the antenna system or design the application scenario of the antenna system according to actual needs. For example, the positions of the antenna 1 and the antenna 2 in the antenna system can be exchanged, and the like.
[0110] The first partition is arranged between the antenna 1 and the antenna 3, and is used to improve the isolation of the antenna 1 and the antenna 3. The second partition is arranged between the antenna 3 and the antenna 2, and is used to improve the isolation of the antenna 3 and the antenna 2. The size of the first partition and the second partition needs to be adapted to the appearance of the car machine. For example, the length of the first partition and the second partition is 37-x1 mm, the width is 31.5-y1 mm, and the thickness is greater than or equal to 1-z1 mm, where x1, y1 and z1 are greater than or equal to 0 and less than or equal to a preset value, for example, 10 mm. It can be understood that in the embodiments of the present application, the preset values less than or equal to x1, y1 and z1 can be the same or different. The first partition and the second partition can be composed of non-metallic materials or composite materials, for example, the first partition and the second partition are composed of polycarbonate or acrylonitrile-butadiene-styrene copolymer materials, to meet the application scenarios in most environments (for example, minus 40 degrees Celsius to 85 degrees Celsius).
[0111] The reflecting plate can be connected with the metal base, and the included angle between the reflecting plate and the metal base is a third preset value. On the other hand, the first partition can be connected with the metal base and the reflecting plate, and the second partition can be connected with the metal base and the reflecting plate. In this way, the setting of the reflecting plate can play a good fixing role and prolong the service life of the internal antennas of the antenna system. The metal base can be made of stainless steel material, because the performance of stainless steel material is superior, the performance under salt spray test is good, and the material reliability is high.
[0112] The antenna 1, the antenna 3 and the antenna 2 can be connected with three radio frequency cables respectively, and the three radio frequency cables can be connected with the shell of the car machine through three through holes on the metal base. As shown in FIG. 3, each cable can be welded on the pin of the corresponding antenna, the inner conductor core of the radio frequency cable is connected with the antenna feed point, and the outer conductor of the cable is grounded. The length of the radio frequency cable corresponding to the antenna 1, the antenna 3 and the antenna 2 can depend on the assembly scheme of the antenna system, and the length of the radio frequency cable can be set with a certain redundancy (that is, the actual length of the radio frequency cable is greater than the preset length), so that the radio frequency cable is not easy to break, so as to improve the reliability of the radio frequency connection. For example, as shown in FIG. 4, the length of the radio frequency cable corresponding to the antenna 1, the antenna 3 and the antenna 2 can be 42.5mm, 41.5mm and 43.5mm respectively, and in addition, the three radio frequency cables can be connected with the car machine through a connector, and the connector can be welded on the PCB board of the car machine to transmit the radio frequency signal. For example, the three radio frequency cables can be buckled on the PCB board through the connector to realize the connection with the car machine, or the three radio frequency cables can be connected with the car machine through a plug. It should be noted that the specific connection mode of the different radio frequency cables with the car machine can be different or the same, and the present application does not make specific limitation.
[0113] The metal base can be connected with the car machine, and the connection mode can be welding, riveting, buckle connection, bonding or screw nut connection. For example, in FIG. 2, the metal base and the car machine adopt screw nut connection, that is, four nested nuts are arranged on the metal base, the four nested nuts can accommodate screws, so that the metal base is connected with the shell of the car machine. In addition, a certain gap can be left between the metal base and the shell of the car machine. For example, as shown in FIG. 5, the height of the first partition plate and the second partition plate can be set to 37.5mm, the height of the three antennas can be set to 7.7mm, the height of the four nested nuts can be close to the height of the antennas, and the interval between the metal base and the shell of the car machine can be set to 1mm.
[0114] Optionally, a plurality of holes or a plurality of openings can be arranged on the first partition plate and / or the second partition plate, so as to optimize the isolation of each antenna. Specifically, the hole structure or the opening structure on the first partition plate and / or the second partition plate can be used as a resonance structure between the antennas, which can make the signals radiated by the antennas on both sides of the partition plate cancel out when the phases are opposite, thereby improving the isolation of the antennas on both sides of the partition plate.
[0115] For example, as shown in FIG. 6, three openings are arranged on the first partition plate and / or the second partition plate, so as to further improve the isolation on both sides of the partition plate. The holes and the size of the first partition plate and the second partition plate can be pre-set, and the upper limit of the pre-set value is to ensure the structural reliability of the first partition plate and the second partition plate.
[0116] Optionally, the surface of the first partition plate and / or the second partition plate can be thickened to form a wave shape or a hollow (e.g., edge serration) shape.
[0117] Optionally, a plurality of positioning holes can be formed on the metal bottom plate to facilitate the fixation of the antenna system on the shell of the vehicle machine.
[0118] The antenna system provided by the embodiments of the present application integrates star flash, WiFi and Bluetooth communication technologies. When part or all of the above communication technologies are used simultaneously, the interference between the antennas corresponding to the communication technologies can be reduced. When the antenna system is applied to a vehicle, the vehicle and external devices can realize high-quality data transmission.
[0119] In one embodiment, an antenna box is provided, which includes a shell for protecting the antenna system and the antenna system in the above embodiments.
[0120] Optionally, the antenna box is applied to a vehicle and connected with a vehicle machine.
[0121] For example, as shown in FIGS. 7 and 8, the antenna box and the shell of the vehicle machine can be combined and installed on the vehicle. The length of the shell of the vehicle machine and the antenna box can be 178-x2 mm, the width of the shell of the vehicle machine can be 182-y2 mm, and the height of the shell of the vehicle machine can be 62-z2 mm, where x2, y2 and z2 are greater than or equal to 0 and less than or equal to a preset value, for example, 5 mm. It can be understood that in the embodiments of the present application, the preset values of x2, y2 and z2 can be the same or different.
[0122] For example, as shown in FIG. 9, the specific manner in which the antenna box is connected with the vehicle machine can be that the antenna box is connected with the vehicle machine through a plurality of cables and connectors. The connectors can be welded on the PCB board of the vehicle machine to transmit radio frequency signals. For example, the cables can be buckled on the PCB board through the connectors to realize the connection with the vehicle machine. Alternatively, the cables can also be connected with the vehicle machine through plug-in mode. It should be noted that the specific manners in which different radio frequency cables are connected with the vehicle machine can be different or the same, which is not limited in the present application.
[0123] It should be noted that the sizes of the antenna box and the vehicle machine shown in FIGS. 7 and 8 are only exemplary descriptions, and a person skilled in the art can change the sizes of the antenna box and the vehicle machine according to actual needs.
