Description

SPECIFICATIONTITLE OF INVENTION: INTERNET OF VEHICLES TERMINAL, COMMUNICATION UNIT, AND VEHICLETECHNICAL FIELD

[01] This application relates to the field of communication technologies, and in particular, to an Internet of Vehicles terminal, a communication unit, and a vehicle.BACKGROUND

[02] With the intelligent development of vehicles, more and more functional modules are deployed in the vehicle. These functional modules may be connected to a network to implement functions such as vehicle status sensing, fault diagnosis, and intelligent control. For example, the vehicle may include a telematics box (telematics box, TBox) and other electrical control units (electrical control units, ECUs). In an Internet of Vehicles scenario, the TBox can provide an Internet access capability for other ECUs in the vehicle.

[03] In some specific implementations, an in-vehicle TBox may include a first storage unit and a communication unit. The first storage unit may be an embedded multimedia card (embedded multimedia card, eMMC). A capacity of the first storage unit may be a standard specification of 4 GB, 8 GB, 16 GB, or 32 GB. The first storage unit may store vehicle information (a vehicle identification number, a vehicle model, and the like), driving data (a driving speed, fuel consumption, and the like), and navigation data (such as current location data of the vehicle and historical driving trajectories). The communication unit may include a plurality of radio frequency components, a central processing unit, and a second storage unit. The second storage unit may store calibration parameters of the radio frequency components, a boot program (BOOT image) for booting the communication unit, a firmware software package, a system program, and the like.

Therefore, storing only the data such as the vehicle information, the driving data, and the navigation data in the first storage unit may cause resource waste of the first storage unit.

[061] The illustrative embodiments of this application include but are not limited to an Internet of Vehicles terminal, a communication unit, and a vehicle.

[062] It may be understood that the communication unit mentioned in the embodiments of this application may be any unit with a function of communication, such as a mobile communication unit or a wireless communication unit.

[063] It may be understood that the communication unit mentioned in the embodiments of this application is applicable to a telematics box.

[064] The following describes an Internet of Vehicles scenario. FIG. 1 shows a diagram of an Internet of Vehicles scenario. As shown in FIG. 1, the Internet of Vehicles scenario includes a cloud platform 110, another vehicle 120, roadside infrastructure 130, a base station 140, a global navigation satellite system (global navigation satellite system, GNSS) 150, and a vehicle 160. The vehicle 160 includes a telematics box 161, a vehicle body network 162, and an in-vehicle central control unit 163.

[065] The cloud platform 110 may provide services such as a unified open interface, device access, data analysis, connection management, and calling.

[066] In some specific implementations, the telematics box 161 may receive an electromagnetic wave signal (such as an image signal) transmitted by any one of the cloud platform 110, the another vehicle 120, the roadside infrastructure 130, the base station 140, and the global navigation satellite system 150, perform processing such as filtering and demodulation on the electromagnetic wave signal to obtain a low-frequency baseband signal, and transmit the low-frequency baseband signal to the in-vehicle central control unit 163 through a network bus, for example, a controller area network (controller area network, CAN) bus, a local interconnect network (local interconnect network, LIN) bus, a FlexRay bus, a media oriented system transport (media oriented system transport, MOST) bus, a universal serial bus (universal serial bus, USB), or Ethernet for related processing. For example, the in-vehicle central control unit 163 may control a central control screen of the vehicle 160 to display an image or a video corresponding to the image signal.

[067] In some other specific implementations, the telematics box 161 may receive a to-be-transmitted signal (for example, a location signal) transmitted by the in-vehicle central control unit 163, perform processing such as modulation and amplification on the to-be-transmitted signal to obtain a radio frequency signal, and transmit the radio frequency signal to any one of the cloud platform 110, the another vehicle 120, the roadside infrastructure 130, the base station 140, and the global navigation satellite system 150. For example, the telematics box 161 may transmit the radio frequency signal corresponding to the location signal to another vehicle, so that the another vehicle performs driving route planning.

[068] The following describes the telematics box 161 in detail with reference to FIG. 2. As described above, the telematics box 161 may include a first storage unit 200 and a communication unit 210.

[069] The first storage unit 200 may be an embedded multimedia card. The capacity of the first storage unit 200 may be a standard specification of 4 GB, 8 GB, 16 GB, or 32 GB. The first storage unit 200 may store data such as vehicle information (a vehicle identification number, a vehicle model, and the like), driving data (a driving speed, fuel consumption, and the like), and navigation data (such as current location data of the vehicle and historical driving trajectories).

[070] The communication unit 210 may include radio frequency components such as a radio frequency front-end (radio frequency front-end, RFFE) 211, a filter 212, a modem 213, and a power amplifier 214. The radio frequency components such as the radio frequency front-end 211, the filter 212, the modem 213, and the power amplifier 214 may be integrated on a radio frequency integrated circuit (radio frequency integrated circuit, RFIC). The communication unit 210 may further include a central processing unit (central processing unit, CPU) 220 and a second storage unit 230.

[071] In some optional examples, the telematics box may further include units such as an antenna diagnostic unit, a power management unit, a Wi-Fi unit, an Ethernet unit, a Bluetooth unit, and a GNSS unit.

[072] In some embodiments, the second storage unit 230 may store calibration parameters of radio frequency components such as the radio frequency front-end (radio frequency front-end, RFFE) 211, the filter 212, the modem 213, and the power amplifier 214, and store data such as a boot program (BOOT image) for booting the communication unit 210, a firmware software package, and a system program. Because the capacity required by the boot program (BOOT image), the firmware software package, the system program, and the like of the communication unit 210 is relatively large, the second storage unit 230 of the communication unit 210 requires a relatively large capacity. In this way, storing the calibration parameters of the radio frequency components and the data such as the boot program (BOOT image) for booting the communication unit 210, the firmware software package, and the system program in the second storage unit 230 of the communication unit 210 not only increases manufacturing costs of the communication unit 210, but also causes resource waste of the first storage unit 200 in the telematics box 161.

[073] To resolve the foregoing problem, embodiments of this application provide a communication unit. Data that needs to be stored in a storage unit of the communication unit is split to obtain personalized data (such as a radio frequency calibration parameter and a baseband calibration parameter) and common data (such as a boot program (BOOT image), a firmware software package, and a system program) of the communication unit. The personalized data of the communication unit is stored in the storage unit of the communication unit, and the common data of the communication unit is stored in a storage unit of an in-vehicle TBox. In this way, only the personalized data of the communication unit is stored in the storage unit of the communication unit, and the communication unit only needs to be provided with a storage unit having a relatively small capacity, so that manufacturing costs of the communication unit can be reduced. In addition, the common data of the communication unit is stored in the storage unit of the in-vehicle TBox, so that a capacity of the storage unit of the in-vehicle TBox can be fully utilized, thereby reducing resource waste of the storage unit of the in-vehicle TBox.

[074] It may be understood that the personalized data may include calibration parameters of radio frequency components in the communication unit, such as a transmit power, a receiver sensitivity, or an error vector magnitude (error vector magnitude, EVM). A larger transmit power indicates a wider coverage area and stronger penetration of a radio frequency signal. The receiver sensitivity is a minimum power of a radio frequency signal that can be detected by the communication unit. The error vector magnitude is used to evaluate quality of a modulated signal. A smaller error vector magnitude indicates a smaller difference between a modulated signal and an ideal modulated signal.

[075] The following describes in detail the communication unit 210 mentioned in the embodiments of this application.

[076] Still as shown in FIG. 2, the communication unit 210 may include the second storage unit 230, and the second storage unit 230 may store calibration parameters of radio frequency components in the communication unit 210. For example, the second storage unit 230 may store transmit power calibration parameters of the radio frequency components. For example, the transmit power calibration parameters may include a gain calibration parameter, and the gain calibration parameter may be used to calibrate a gain of the power amplifier 214 in the radio frequency components, so that the gain of the power amplifier 214 can reach an expected gain, and a power of a radio frequency signal transmitted by the communication unit can reach an expected power.

[077] As described above, the communication unit 210 may further include radio frequency components such as the radio frequency front-end 211, the filter 212, the modem 213, and the power amplifier 214, and the central processing unit 220.

[078] In some specific implementations, the radio frequency front-end 211 may receive, through an antenna port, radio frequency signals transmitted by a transmitting end (for example, the cloud platform 110, the another vehicle 120, the roadside infrastructure 130, the base station 140, or the global navigation satellite system 150 in FIG. 1). The filter 212 may perform filtering processing on the radio frequency signals, that is, selectively pass or suppress radio frequency signals within a specific frequency range, to obtain a filtered radio frequency signal. The modem 213 may demodulate an original low-frequency baseband signal (for example, an image signal) from the filtered radio frequency signal, and transmit the original low-frequency baseband signal to the central processing unit 220. The central processing unit 220 may perform related processing based on the low-frequency baseband signal. For example, the central processing unit 220 may display, by using a display screen, an image or a video corresponding to the image signal.

[079] In some other specific implementations, the central processing unit 220 may further transmit a to-be-transmitted signal (for example, a location signal of a vehicle) to the modem 213. The modem 213 may perform encoding processing on the to-be-transmitted signal to obtain a digital signal, load the digital signal to a high-frequency carrier to obtain a modulated signal whose frequency range is within a radio frequency range, and transmit the modulated signal to the power amplifier. For example, in amplitude shift keying modulation, when the digital signal is "1", the amplitude of the carrier is at a high level, and when the digital signal is "0", the amplitude of the carrier is at a low level. The power amplifier 214 may amplify the modulated signal to increase a power of the modulated signal, so as to ensure that the modulated signal can be received by a receiving end (for example, the cloud platform 110, the another vehicle 120, the roadside infrastructure 130, the base station 140, or the global navigation satellite system 150 in FIG. 1).

[080] In actual application, due to factors such as manufacturing tolerance and temperature, performance of different communication units 210 manufactured based on the same production process is different. Therefore, to ensure the performance of the communication unit 210, when the communication unit 210 is shipped from a factory, a communication unit manufacturer needs to perform radio frequency calibration on the radio frequency components in the communication unit 210, and store calibration parameters of the radio frequency components obtained through the calibration in the second storage unit of the communication unit 210.

[081] The calibration parameters may include calibration parameters such as a transmit power, a receiver sensitivity, and an error vector magnitude. A larger transmit power indicates a wider coverage area and stronger penetration of a radio frequency signal. The receiver sensitivity is a minimum power of an input signal that can be detected. The error vector magnitude is used to evaluate quality of a modulated signal. A smaller error vector magnitude indicates a smaller difference between a modulated signal and an ideal modulated signal.

[082] In the embodiments of this application, only the calibration parameters of the radio frequency components in the communication unit 210 are stored in the second storage unit 230 of the communication unit 210, and the communication unit 210 only needs to be provided with a storage unit having a relatively small capacity, so that manufacturing costs of the communication unit 210 can be reduced.

[083] As described above, in the embodiments of this application, the personalized data of the communication unit 210 is stored in the second storage unit 230, and the common data of the communication unit 210 is stored in the first storage unit 200 of the telematics box 161. The following describes in detail the telematics box mentioned in the embodiments of this application.

[084] Still as shown in FIG. 2, in some embodiments, the telematics box 161 may include the first storage unit 200 and the communication unit 210. The first storage unit 200 may store data, such as a boot program (BOOT image), a firmware software package, and a system program of the communication unit 210, vehicle information (a vehicle identification number, a vehicle model, and the like), driving data (a driving speed, fuel consumption, and the like), navigation data (such as current location data of the vehicle and historical driving trajectories), an antenna resonance frequency threshold, and power management control logic. The communication unit 210 may include the second storage unit 230, and the second storage unit 230 may store a calibration parameter of a radio frequency component in the communication unit 210.

[085] In some specific implementations, in response to invoking the antenna resonance frequency threshold in the first storage unit 200, the communication unit 210 may control, based on the antenna resonance frequency threshold and a current resonance frequency of an antenna, the antenna to be disconnected or connected. For example, when the current resonance frequency of the antenna is greater than the antenna resonance frequency threshold, the communication unit controls the antenna to be connected. When the current resonance frequency of the antenna is less than or equal to the antenna resonance frequency threshold, the communication unit controls the antenna to be disconnected.

[086] In some other specific implementations, the communication unit 210 may be powered on, powered off, put into a sleep mode, or awakened in response to invoking the power management control logic in the first storage unit 200.

[087] In the embodiments of this application, only the calibration parameters of the radio frequency components in the communication unit 210 are stored in the second storage unit 230 of the communication unit 210, and the communication unit 210 only needs to be provided with a storage unit having a relatively small capacity, so that manufacturing costs of the communication unit 210 can be reduced. In addition, the boot program (BOOT image), the firmware software package, the system program, and the like of the communication unit 210 are stored in the first storage unit 200 of the telematics box 161, so that a capacity of the first storage unit 200 of the telematics box 161 can be fully utilized, thereby reducing resource waste of the first storage unit 200 of the telematics box 161.

[088] The following describes manufacturing processes of telematics boxes in different embodiments.

[089] As shown in FIG. 3A, for a telematics box 161 in some embodiments, a common parameter of a communication unit 210 is stored in a second storage unit 230. Correspondingly, the manufacturing process of the telematics box 161 includes a plurality of phases, for example, may include a first phase, a second phase, a third phase, and a fourth phase.

[090] In the first phase, a communication unit manufacturer solders the communication unit 210 onto a mainboard of the telematics box 161, and writes a boot program (BOOT image), a firmware software package, a system program, and the like of the communication unit 210 into the second storage unit 230 of the communication unit 210.

[091] In the second phase, a processor on the mainboard of the telematics box 161 sends a boot instruction to a central processing unit 220 of the communication unit 210, and the central processing unit 220 may load and run the boot program (BOOT image), the firmware software package, the system program, and the like of the communication unit 210 from the second storage unit 230, so as to control the communication unit 210 to be in an operating state. Further, calibration parameters of radio frequency components may be obtained by detecting input and output data of the radio frequency components, and the calibration parameters of the radio frequency components are written into the second storage unit 230 of the communication unit 210.

[092] The central processing unit 220 may transmit a to-be-transmitted signal (for example, a location signal of a vehicle) to a modem 213. The modem 213 may perform encoding processing on the to-be-transmitted signal to obtain a digital signal, load the digital signal to a high-frequency carrier to obtain a modulated signal whose frequency range is within a radio frequency range, and transmit the modulated signal to a power amplifier. The power amplifier may amplify the modulated signal to increase a power of the modulated signal. At this time, the power of the modulated signal may be detected by a detection device, and a transmit power calibration parameter may be determined based on the power of the modulated signal and an expected power.

[093] For example, a gain calibration parameter of the power amplifier is determined based on a difference between the power of the modulated signal and the expected power. The gain calibration parameter may be used to calibrate a gain of the power amplifier in the radio frequency components, so that the gain of the power amplifier can reach an expected gain, and a power of a radio frequency signal transmitted by the communication unit can reach an expected power.

[094] In the third phase, the communication unit manufacturer may perform software upgrade processing on the boot program (BOOT image), the firmware software package, the system program, and the like of the communication unit 210 in the second storage unit 230, to ensure that the boot program (BOOT image), the firmware software package, the system program, and the like stored in the second storage unit 230 can control the communication unit 210 to be in an operating state.

[095] In the fourth phase, a telematics box manufacturer may perform software upgrade processing on the boot program (BOOT image), the firmware software package, the system program, and the like of the communication unit 210 in the second storage unit 230, to further ensure that the boot program (BOOT image), the firmware software package, the system program, and the like stored in the second storage unit 230 can control the communication unit 210 to be in an operating state.

[096] As shown in FIG. 3B, for a telematics box 161 in some other embodiments, a common parameter of a communication unit 210 is stored in a first storage unit 200. Compared with the manufacturing process of the telematics box 161 in some of the foregoing embodiments, the communication unit manufacturer may streamline the first phase and the third phase to further reduce manual manufacturing costs of the communication unit 210.

[097] In addition, in the second phase, the communication unit manufacturer may write a boot program (BOOT image), a firmware software package, a system program, and the like of the communication unit 210 into a storage unit on a test mainboard, and may connect the communication unit 210 to the test mainboard via a fixture and a pogo pin. A processor on the test mainboard may load and run the boot program (BOOT image), the firmware software package, the system program, and the like of the communication unit 210, so as to control the communication unit 210 to be in an operating state. Further, calibration parameters of radio frequency components may be obtained by detecting input and output data of the radio frequency components, and the calibration parameters of the radio frequency components are written into the second storage unit 230 of the communication unit 210.

[098] In the fourth phase, a telematics box manufacturer solders the communication unit 210 onto a mainboard of the telematics box 161, writes packages such as the boot program (BOOT image), the firmware software package, and the system program that are delivered by the communication unit manufacturer together with the communication unit 210 into the first storage unit 200 of the telematics box 161, and performs software upgrade processing on the boot program (BOOT image), the firmware software package, the system program, and the like of the communication unit 210 in the first storage unit 200, to further ensure that the boot program (BOOT image), the firmware software package, the system program, and the like stored in the first storage unit 200 can control the communication unit 210 to be in an operating state.

[099] The following describes in detail a manufacturing process of the telematics box 161 mentioned in the embodiments of this application.

[0100] As shown in FIG. 4A and FIG. 4B, in a production line (that is, the second phase mentioned above), the boot program (BOOT image), the firmware software package, the system program, and the like of the communication unit 210 may be written into the storage unit of the test mainboard. In addition, the communication unit 210 may be connected to the test mainboard via a fixture and a pogo pin, so that the communication unit 210 can be normally powered on and perform radio frequency component calibration under control of the processor on the test mainboard.

[0101] In some optional examples, the processor on the mainboard of the telematics box 161 sends a start instruction to the central processing unit 220 of the communication unit 210, and the central processing unit 220 may load and run the boot program (BOOT image), the firmware software package, the system program, and the like of the communication unit 210 from the second storage unit 230, so as to control the communication unit 210 to be in an operating state. Further, the calibration parameters of the radio frequency components may be obtained by detecting the input and output data of the radio frequency components, and the calibration parameters of the radio frequency components are written into the second storage unit 230 of the communication unit 210. Then, the boot program (BOOT image), the firmware software package, the system program, and the like of the communication unit 210 may be delivered together with the communication unit 210 to the telematics box manufacturer.

[0102] The central processing unit 220 may transmit a to-be-transmitted signal (for example, a location signal of a vehicle) to the modem 213. The modem 213 may perform encoding processing on the to-be-transmitted signal to obtain a digital signal, load the digital signal to a high-frequency carrier to obtain a modulated signal whose frequency range is within a radio frequency range, and transmit the modulated signal to the power amplifier. The power amplifier may amplify the modulated signal to increase a power of the modulated signal. At this time, the power of the modulated signal may be detected by a detection device, and a transmit power calibration parameter may be determined based on the power of the modulated signal and an expected power.

[0103] For example, a gain calibration parameter of the power amplifier is determined based on a difference between the power of the modulated signal and the expected power. The gain calibration parameter may be used to calibrate a gain of the power amplifier in the radio frequency components, so that the gain of the power amplifier can reach an expected gain, and a power of a radio frequency signal transmitted by the communication unit can reach an expected power.

[0104] Then, the telematics box manufacturer solders the communication unit 210 onto the mainboard of the telematics box 161, writes packages such as the boot program (BOOT image), the firmware software package, and the system program that are delivered by the communication unit manufacturer together with the communication unit 210 into the first storage unit 200 of the telematics box 161, and performs software upgrade processing on the boot program (BOOT image), the firmware software package, the system program, and the like of the communication unit 210 in the first storage unit 200, to further ensure that the boot program (BOOT image), the firmware software package, the system program, and the like stored in the first storage unit 200 can control the communication unit 210 to be in an operating state.

[0105] In a process of using the telematics box, if a processor (not shown in the figure) in the telematics box 161 loads and runs the boot program (BOOT image), the firmware software package, the system program, and the like of the communication unit 210 from the first storage unit 200, the communication unit 210 may be controlled to be in an operating state.

[0106] In some specific implementations, the filter 212 in the communication unit 210 may perform filtering processing on radio frequency signals transmitted by a transmitting end (for example, the cloud platform 110, the another vehicle 120, the roadside infrastructure 130, the base station 140, or the global navigation satellite system 150 in FIG. 1), that is, selectively pass or suppress radio frequency signals within a specific frequency range, to obtain a filtered radio frequency signal. The modem 213 may demodulate an original low-frequency baseband signal (for example, an image signal) from the filtered radio frequency signal, and transmit the original low-frequency baseband signal to the central processing unit 220. The central processing unit 220 in the communication unit 210 may return the low-frequency baseband signal to the processor in the telematics box 161, and the processor in the telematics box 161 may perform related processing based on the low-frequency baseband signal. For example, an image or a video corresponding to the image signal is generated, and the processed signal is transmitted to an in-vehicle central control unit 180 via a network bus, such as a controller area network (controller area network, CAN) bus, a local interconnect network (local interconnect network, LIN) bus, a FlexRay bus, a media oriented system transport (media oriented system transport, MOST) bus, a universal serial bus (universal serial bus, USB), or Ethernet, so that the in-vehicle central control unit 180 may display the image or the video corresponding to the image signal.

[0107] In some other specific implementations, the central processing unit 220 may further transmit a to-be-transmitted signal (for example, a location signal of a vehicle) to the modem 213. The modem 213 may perform encoding processing on the to-be-transmitted signal to obtain a digital signal, load the digital signal to a high-frequency carrier to obtain a modulated signal whose frequency range is within a radio frequency range, and transmit the modulated signal to the power amplifier. The power amplifier may amplify the modulated signal to increase a power of the modulated signal, so as to ensure that the modulated signal can be received by a receiving end (for example, the cloud platform 110, the another vehicle 120, the roadside infrastructure 130, the base station 140, or the global navigation satellite system 150 in FIG. 1).

[0108] In the embodiments of this application, for the communication unit manufacturer, the first phase and the third phase in the existing solution are streamlined to further reduce manual manufacturing costs of the communication unit 210. In addition, only the calibration parameters of the radio frequency components in the communication unit 210 are stored in the second storage unit 230 of the communication unit 210, and the communication unit 210 only needs to be provided with a storage unit having a relatively small capacity, so that manufacturing costs of the communication unit 210 can be reduced. For the telematics box manufacturer, the boot program (BOOT image), the firmware software package, the system program, and the like of the communication unit 210 are stored in the first storage unit 200 of the telematics box 161, so that a capacity of the first storage unit 200 of the telematics box 161 can be fully utilized, thereby reducing resource waste of the first storage unit 200 of the telematics box 161.
