Description

Internet of Vehicles terminal, communication unit and vehicle

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on February 23, 2024, with application number 202410204091.4 and application name “A vehicle network terminal, communication unit and vehicle”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a vehicle networking terminal, a communication unit, and a vehicle. Background Art

[0003] As vehicles become increasingly intelligent, more and more functional modules are being deployed in them. These modules can connect to the network to implement functions such as vehicle status awareness, fault diagnosis, and intelligent control. For example, a vehicle may include a telematics box (TBox) and other electronic control units (ECUs). In a connected vehicle scenario, the TBox can provide Internet access to other ECUs in the vehicle.

[0004] In some specific implementations, the vehicle-mounted TBox may include a first storage unit and a communication unit. The first storage unit may be an embedded multimedia card (eMMC), and the capacity of the first storage unit may be a standard specification of 4GB, 8GB, 16GB, or 32GB. The first storage unit may store vehicle information (vehicle identification number, vehicle model, etc.), driving data (driving speed, fuel consumption, etc.), and navigation data (vehicle current location data, historical driving trajectory, etc.). The communication unit may include multiple 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 starting the communication unit, a firmware software package, a system program, and the like.

[0005] Since the capacity of the first storage unit is generally standard, and the capacity required for data such as vehicle information, driving data, and navigation data is far smaller than the standard specification of the first storage unit, storing data such as vehicle information, driving data, and navigation data only in the first storage unit will result in a waste of resources of the first storage unit.

[0006] Summary of the Invention

[0007] In order to solve the problem that storing vehicle information, driving data, navigation data and other data only in the first storage unit will cause waste of resources of the first storage unit, an embodiment of the present application provides a vehicle network terminal, a communication unit and a vehicle.

[0062] The illustrative embodiments of the present application include, but are not limited to, a vehicle networking terminal, a communication unit, and a vehicle.

[0063] It can be understood that the communication unit mentioned in the embodiments of the present application can be any unit with communication function, such as a mobile communication unit, a wireless communication unit, etc.

[0064] It can be understood that the communication unit mentioned in the embodiment of the present application can be applicable to the Internet of Vehicles terminal box.

[0065] The following describes the IoV scenario. Figure 1 shows a schematic diagram of an IoV scenario. As shown in Figure 1, the IoV scenario includes a cloud platform 110, other vehicles 120, roadside infrastructure 130, base stations 140, a global navigation satellite system (GNSS) 150, and a vehicle 160. Vehicle 160 includes an IoV terminal box 161, a vehicle body network 162, and an onboard central control system 163.

[0066] Among them, the cloud platform 110 can provide unified open interfaces, device access, data analysis, connection management, call and other services.

[0067] In some specific implementations, the Internet of Vehicles terminal box 161 can receive electromagnetic wave signals (such as image signals) sent by any device among the cloud platform 110, other vehicles 120, roadside infrastructure 130, base station 140, and global navigation satellite system 150, filter, demodulate, and process the electromagnetic wave signals to obtain low-frequency baseband signals, and transmit the processed low-frequency baseband signals through a network bus, such as a controller area network (CAN) bus, a local interconnect network (LIN) bus, a FlexRay bus, a media oriented system transport (MOST) bus, a universal serial bus (USB), Ethernet, etc. to the on-board central control 163 for related processing. For example, the on-board central control 163 can control the central control screen of the vehicle 160 to display the image or video corresponding to the image signal.

[0068] In other specific implementations, the IoV terminal box 161 may also receive a signal to be transmitted (e.g., a location signal) from the onboard central control 163, modulate and amplify the signal to be transmitted to obtain a radio frequency signal, and transmit the radio frequency signal to any one of the cloud platform 110, other vehicles 120, roadside infrastructure 130, base station 140, and global navigation satellite system 150. For example, the IoV terminal box 161 may transmit the radio frequency signal corresponding to the location signal to other vehicles so that the other vehicles can plan their driving routes.

[0069] The following describes the vehicle networking terminal box 161 in detail with reference to FIG2 . As mentioned above, the vehicle networking terminal box 161 may include a first storage unit 200 and a communication unit 210 .

[0070] Among them, the first storage unit 200 can be an embedded multimedia card, the capacity of the first storage unit 200 can be a standard specification of 4GB, 8GB, 16GB or 32GB, and the first storage unit 200 can store vehicle information (vehicle identification number, vehicle model, etc.), driving data (driving speed, fuel consumption, etc.), navigation data (vehicle's current location data, historical driving trajectory, etc.) and other data.

[0071] The communication unit 210 may include radio frequency front-end (RFFE) 211, filter 212, modem 213, and power amplifier 214, among other radio frequency components. These components may be integrated on a radio frequency integrated circuit (RFIC). The communication unit 210 may also include a central processing unit (CPU) 220 and a second storage unit 230.

[0072] In some optional examples, the Internet of Vehicles terminal box may also include an antenna diagnostic unit, a power management unit, a WIFI unit, an Ethernet unit, a Bluetooth unit, a GNSS unit, and other units.

[0073] In some embodiments, the second storage unit 230 can store calibration parameters for RF components such as the radio frequency front-end (RFFE) 211, filter 212, modem 213, and power amplifier 214, as well as data such as the boot program (BOOT image), firmware software package, and system program for starting the communication unit 210. Because the boot program (BOOT image), firmware software package, and system program for the communication unit 210 require a relatively large amount of storage, the second storage unit 230 of the communication unit 210 requires a relatively large amount of storage. Storing the calibration parameters for the RF components and the boot program (BOOT image), firmware software package, and system program for starting the communication unit 210 in the second storage unit 230 of the communication unit 210 not only increases the manufacturing cost of the communication unit 210 but also wastes resources in the first storage unit 200 of the connected vehicle terminal box 161.

[0074] In order to solve the above problems, an embodiment of the present application provides a communication unit. By splitting the data that needs to be stored in the storage unit of the communication unit, the personalized data of the communication unit (such as radio frequency calibration parameters, baseband calibration parameters) and common data (such as boot program (BOOT image), firmware software package, system program, etc.) are obtained, and 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 the storage unit of the vehicle-mounted TBox. In this way, by only storing the personalized data of the communication unit in the storage unit of the communication unit, only a storage unit with a smaller capacity needs to be set in the communication unit, which can reduce the manufacturing cost of the communication unit, and by storing the common data of the communication unit in the storage unit of the vehicle-mounted TBox, the capacity of the storage unit of the vehicle-mounted TBox can be fully utilized, reducing the waste of resources of the storage unit of the vehicle-mounted TBox.

[0075] It is understood that the personalized data may include calibration parameters of the RF components in the communication unit, such as transmit power, receive sensitivity, and error vector magnitude (EVM). The greater the transmit power, the wider the coverage range and the greater the penetration of the RF signal. Receive sensitivity refers to the minimum power of the RF signal that can be detected by the communication unit. Error vector magnitude (EVM) is used to assess the quality of the modulated signal; the smaller the error vector magnitude, the smaller the difference between the modulated signal and the ideal modulated signal.

[0076] The communication unit 210 mentioned in the embodiment of the present application is introduced in detail below.

[0077] Continuing with FIG. 2 , the communication unit 210 may include a second storage unit 230 that may store calibration parameters of the RF component in the communication unit 210. For example, the second storage unit 230 may store transmit power calibration parameters of the RF component. For example, the transmit power calibration parameters may include gain calibration parameters, which may be used to calibrate the gain of the power amplifier 214 in the RF component so that the gain of the power amplifier 214 reaches a desired gain, thereby ensuring that the power of the RF signal transmitted by the communication unit reaches a desired power.

[0078] As mentioned above, the communication unit 210 may further include radio frequency components such as a radio frequency front end 211 , a filter 212 , a modem 213 , and a power amplifier 214 , as well as a central processing unit 220 .

[0079] In some specific implementations, the RF front end 211 can receive the RF signal sent by the transmitter (such as the cloud platform 110, other vehicles 120, roadside infrastructure 130, base station 140, and global navigation satellite system 150 in Figure 1) through the antenna port. The filter 212 can filter the RF signal, that is, selectively pass or suppress the RF signal within a specific frequency range to obtain a filtered RF signal. The modem 213 can demodulate the original low-frequency baseband signal (such as an image signal, etc.) from the filtered RF signal and send it to the central processing unit 220. The central processing unit 220 can perform related processing based on the low-frequency baseband signal. For example, the central processing unit 220 can display the image or video corresponding to the image signal through a display screen.

[0080] In other specific implementations, the central processing unit 220 may also send a signal to be sent (such as a vehicle's position signal, etc.) to the modem 213. The modem 213 may encode the signal to be sent to obtain a digital signal, and load the digital signal to a high-frequency carrier to obtain a modulated signal with a frequency range within the radio frequency range, and send it to the power amplifier. For example, in amplitude shift keying modulation, when the digital signal is "1", the amplitude of the carrier is high, and when the digital signal is "0", the amplitude of the carrier is low. The power amplifier 214 may amplify the modulated signal to increase the power of the modulated signal, thereby ensuring that the modulated signal can be received by the receiving end (such as the cloud platform 110, other vehicles 120, roadside infrastructure 130, base station 140, and global navigation satellite system 150 in Figure 1).

[0081] In actual applications, due to factors such as manufacturing tolerances and temperature, the performance of different communication units 210 prepared based on the same production process may be different. Therefore, in order to ensure the performance of the communication unit 210, when the communication unit 210 leaves the factory, the communication unit manufacturer needs to perform RF calibration on the RF components in the communication unit 210 and store the calibration parameters of the RF components obtained by the calibration in the second storage unit of the communication unit 210.

[0082] Calibration parameters may include transmit power, receive sensitivity, and vector magnitude error (VME). A higher transmit power provides a wider coverage range and greater penetration. Receive sensitivity refers to the minimum detectable input signal power. VME is used to assess the quality of the modulated signal; a smaller VME indicates a smaller difference between the modulated signal and the ideal modulated signal.

[0083] In the embodiment of the present application, by storing only the calibration parameters of the RF components in the communication unit 210 in the second storage unit 230 of the communication unit 210, only a storage unit with a smaller capacity needs to be set in the communication unit 210, which can reduce the manufacturing cost of the communication unit 210.

[0084] As mentioned above, the embodiment of the present application stores the personalized data of the communication unit 210 in the second storage unit 230 and stores the common data of the communication unit 210 in the first storage unit 200 of the vehicle networking terminal box 161. The vehicle networking terminal box mentioned in the embodiment of the present application is described in detail below.

[0085] Continuing with FIG2 , in some embodiments, the IoV terminal box 161 may include a first storage unit 200 and a communication unit 210 . The first storage unit 200 may store the communication unit 210's boot program (BOOT image), firmware software packages, system programs, vehicle information (vehicle identification number, vehicle model, etc.), driving data (driving speed, fuel consumption, etc.), navigation data (vehicle's current location data, historical driving trajectory, etc.), antenna resonant frequency thresholds, power management control logic, and other data. The communication unit 210 may include a second storage unit 230 , which may store calibration parameters for the RF components in the communication unit 210 .

[0086] In some specific implementations, the communication unit 210 may control the antenna to be open or closed based on the antenna resonant frequency threshold and the current resonant frequency of the antenna in response to calling the antenna resonant frequency threshold in the first storage unit 200. For example, when the current resonant frequency of the antenna is greater than the antenna resonant frequency threshold, the communication unit controls the antenna to be closed. When the current resonant frequency of the antenna is less than or equal to the antenna resonant frequency threshold, the communication unit controls the antenna to be open.

[0087] In some other specific implementations, the communication unit 210 may be powered on, powered off, put into sleep mode, or awakened in response to calling the power management control logic in the first storage unit 200 .

[0088] In the embodiment of the present application, by storing only the calibration parameters of the radio frequency components in the communication unit 210 in the second storage unit 230 of the communication unit 210, only a smaller storage unit is required in the communication unit 210, thereby reducing the manufacturing cost of the communication unit 210. Furthermore, by storing the boot program (BOOT image), firmware software package, system program, etc. of the communication unit 210 in the first storage unit 200 of the connected vehicle terminal box 161, the capacity of the first storage unit 200 of the connected vehicle terminal box 161 can be fully utilized, thereby reducing resource waste in the first storage unit 200 of the connected vehicle terminal box 161.

[0089] The following describes the manufacturing process of the Internet of Vehicles terminal box in different embodiments.

[0090] As shown in FIG3A , for the Internet of Vehicles terminal box 161 in some embodiments, the common parameters of the communication unit 210 are stored in the second storage unit 230. Accordingly, the process flow for preparing the Internet of Vehicles terminal box 161 includes multiple stages, such as a first stage, a second stage, a third stage, and a fourth stage.

[0091] In the first stage, the communication unit manufacturer solders the communication unit 210 to the motherboard of the Internet of Vehicles terminal box 161 and writes the boot program (BOOT image), firmware software package, system program, etc. of the communication unit 210 into the second storage unit 230 of the communication unit 210.

[0092] In the second phase, the processor on the mainboard of the IoV terminal box 161 sends a startup command to the central processing unit 220 of the communication unit 210. The central processing unit 220 can then load and run the startup program (BOOT image), firmware software package, system program, etc. of the communication unit 210 from the second storage unit 230 to control the communication unit 210 to maintain an operational state. Furthermore, by detecting the input and output data of the RF component, the calibration parameters of the RF component can be obtained and written to the second storage unit 230 of the communication unit 210.

[0093] The central processing unit 220 can send a signal to be transmitted (e.g., a vehicle's location signal) to the modem 213. The modem 213 can encode the signal to be transmitted to obtain a digital signal, load the digital signal onto a high-frequency carrier, obtain a modulated signal within the radio frequency range, and send it to the power amplifier. The power amplifier can amplify the modulated signal to increase its power. The power of the modulated signal can be detected by a detection device, and a transmit power calibration parameter can be determined based on the power of the modulated signal and the expected power.

[0094] For example, the gain calibration parameters of the power amplifier are determined based on the difference between the power of the modulated signal and the expected power. The gain calibration parameters can be used to calibrate the gain of the power amplifier in the RF component so that the gain of the power amplifier can reach the expected gain, thereby enabling the power of the RF signal sent by the communication unit to reach the expected power.

[0095] In the third stage, the communication unit manufacturer can perform software upgrade processing on the boot program (BOOT image), firmware software package, system program, etc. of the communication unit 210 in the second storage unit 230 to ensure that the boot program (BOOT image), firmware software package, system program, etc. stored in the second storage unit 230 can control the communication unit 210 to be in working state.

[0096] In the fourth stage, the manufacturer of the Internet of Vehicles terminal box can perform software upgrade processing on the boot program (BOOT image), firmware software package, system program, etc. of the communication unit 210 in the second storage unit 230 to further ensure that the boot program (BOOT image), firmware software package, system program, etc. stored in the second storage unit 230 can control the communication unit 210 to be in working state.

[0097] As shown in FIG3B , for the connected vehicle terminal box 161 in some other embodiments, the common parameters of the communication unit 210 are stored in the first storage unit 200. Compared to the manufacturing process of the connected vehicle terminal box 161 in some of the above embodiments, the communication unit manufacturer can streamline the first and third stages to further reduce the labor cost of manufacturing the communication unit 210.

[0098] Furthermore, in the second phase, the communication unit manufacturer can write the startup program (BOOT image), firmware software package, system program, etc. of the communication unit 210 into the storage unit on the test motherboard, and can connect the communication unit 210 to the test motherboard through a fixture and a pin. The processor on the test motherboard can load and run the startup program (BOOT image), firmware software package, system program, etc. of the communication unit 210 to control the communication unit 210 to be in a working state. Furthermore, the calibration parameters of the RF component can be obtained by detecting the input and output data of the RF component, and the calibration parameters of the RF component can be written into the second storage unit 230 of the communication unit 210.

[0099] In the fourth stage, the manufacturer of the Internet of Vehicles terminal box solders the communication unit 210 to the motherboard of the Internet of Vehicles terminal box 161, and writes the boot program (BOOT image), firmware software package, system program and other packages delivered by the communication unit manufacturer with the communication unit 210 into the first storage unit 200 of the Internet of Vehicles terminal box 161, and performs software upgrade processing on the boot program (BOOT image), firmware software package, system program, etc. of the communication unit 210 in the first storage unit 200 to further ensure that the boot program (BOOT image), firmware software package, system program, etc. stored in the first storage unit 200 can control the communication unit 210 to be in working state.

[0100] The following is a detailed introduction to the process of preparing the Internet of Vehicles terminal box 161 mentioned in the embodiment of the present application.

[0101] As shown in Figure 4, during the production line (i.e., the second stage mentioned above), the boot program (BOOT image), firmware software package, system program, etc. of the communication unit 210 can be written into the storage unit of the test motherboard. Furthermore, the communication unit 210 can be connected to the test motherboard via a fixture and eject pins, so that the communication unit 210 can be normally powered on and the RF components can be calibrated under the control of the processor on the test motherboard.

[0102] In some optional embodiments, the processor on the motherboard of the Internet of Vehicles terminal box 161 sends a startup instruction to the central processing unit 220 of the communication unit 210. The central processing unit 220 can load and run the startup program (BOOT image), firmware software package, system program, etc. of the communication unit 210 from the second storage unit 230 to control the communication unit 210 to be in a working state. Furthermore, the calibration parameters of the RF component can be obtained by detecting the input and output data of the RF component, and the calibration parameters of the RF component can be written to the second storage unit 230 of the communication unit 210. The startup program (BOOT image), firmware software package, system program, etc. of the communication unit 210 can then be delivered to the Internet of Vehicles terminal box manufacturer together with the communication unit 210.

[0103] The central processing unit 220 can send a signal to be transmitted (e.g., a vehicle's location signal) to the modem 213. The modem 213 can encode the signal to be transmitted to obtain a digital signal, load the digital signal onto a high-frequency carrier, obtain a modulated signal within the radio frequency range, and send it to the power amplifier. The power amplifier can amplify the modulated signal to increase its power. The power of the modulated signal can be detected by a detection device, and a transmit power calibration parameter can be determined based on the power of the modulated signal and the expected power.

[0104] For example, the gain calibration parameters of the power amplifier are determined based on the difference between the power of the modulated signal and the expected power. The gain calibration parameters can be used to calibrate the gain of the power amplifier in the RF component so that the gain of the power amplifier can reach the expected gain, thereby enabling the power of the RF signal sent by the communication unit to reach the expected power.

[0105] Then, the manufacturer of the Internet of Vehicles terminal box can solder the communication unit 210 to the main board of the Internet of Vehicles terminal box 161, and write the boot program (BOOT image), firmware software package, system program and other packages delivered by the communication unit manufacturer with the communication unit 210 into the first storage unit 200 of the Internet of Vehicles terminal box 161, and perform software upgrade processing on the boot program (BOOT image), firmware software package, system program, etc. of the communication unit 210 in the first storage unit 200 to further ensure that the boot program (BOOT image), firmware software package, system program, etc. stored in the first storage unit 200 can control the communication unit 210 to be in working state.

[0106] During the use of the Internet of Vehicles terminal box, if the processor (not shown) in the Internet of Vehicles terminal box 161 loads and runs the boot program (BOOT image), firmware software package, system program, etc. of the communication unit 210 from the first storage unit 200, the communication unit 210 can be controlled to be in a working state.

[0107] In some specific implementations, the filter 212 in the communication unit 210 can filter the radio frequency signal transmitted by the transmitter (e.g., the cloud platform 110, other vehicles 120, roadside infrastructure 130, base station 140, and global navigation satellite system 150 in FIG1 ), that is, selectively pass or suppress radio frequency signals within a specific frequency range to obtain a filtered radio frequency signal. The modem 213 can demodulate the original low-frequency baseband signal (e.g., an image signal, etc.) from the filtered radio frequency signal and send it to the central processor 220. The central processor 220 in the communication unit 210 can return the low-frequency baseband signal to the processor in the Internet of Vehicles terminal box 161, and the processor in the Internet of Vehicles terminal box 161 can perform relevant processing based on the low-frequency baseband signal. For example, an image or video corresponding to an image signal is generated, and the processed signal is transmitted to the vehicle-mounted central control 180 through a network bus, such as a controller area network (CAN) bus, a local interconnect network (LIN) bus, a FlexRay bus, a media-oriented system transport (MOST) bus, a universal serial bus (USB), Ethernet, etc., and then the vehicle-mounted central control 180 can display the image or video corresponding to the image signal.

[0108] In other specific implementations, the central processor 220 may also send a signal to be transmitted (e.g., a vehicle's location signal) to the modem 213. The modem 213 may encode the signal to be transmitted to obtain a digital signal, load the digital signal onto a high-frequency carrier to obtain a modulated signal within the radio frequency range, and transmit the modulated signal to the power amplifier. The power amplifier may amplify the modulated signal to increase its power, thereby ensuring that the modulated signal can be received by a receiving end (e.g., the cloud platform 110, other vehicles 120, roadside infrastructure 130, base station 140, or global navigation satellite system 150 in FIG1 ).

[0109] In the embodiments of the present application, for communication unit manufacturers, the first and third stages of the existing solution are streamlined to further reduce the manual manufacturing cost of the communication unit 210. In addition, by storing only the calibration parameters of the RF components in the communication unit 210 in the second storage unit 230 of the communication unit 210, only a smaller storage unit is required in the communication unit 210, thereby reducing the manufacturing cost of the communication unit 210. For the manufacturer of the Internet of Vehicles terminal box, storing the boot program (BOOT image), firmware software package, system program, etc. of the communication unit 210 in the first storage unit 200 of the Internet of Vehicles terminal box 161 can fully utilize the capacity of the first storage unit 200 of the Internet of Vehicles terminal box 161 and reduce the waste of resources in the first storage unit 200 of the Internet of Vehicles terminal box 161.
