Description

Technical Field

[0001] The present invention relates to the technical field of vehicle networking data storage and query, and in particular, to a vehicle networking data storage and query system and method. Background Art

[0002] At present, the functions of the Internet of Vehicles can be divided into multiple categories according to their functional characteristics and usage scenarios. Among them, the remote vehicle status query function, as one of the important subcategories, has almost become a standard configuration function for vehicles with Internet of Vehicles functions. The remote vehicle query function usually initiates a remote vehicle status query request by a terminal device (for example, a mobile phone, a web terminal, etc.), which is sent to the vehicle via the back end (for example, the Internet of Vehicles cloud platform). After the first device (for example, ECU) with network access capability on the vehicle side receives the query request, it wakes up the second device (for example, including multiple ECUs or edge nodes) storing the information to be queried through the in-vehicle network bus. Since the common usage scenario of remote query is that the vehicle user is away from the vehicle, the vehicle bus is in a dormant state in most cases, so it is necessary to wake up the ECU and send a query request (or read the bus signal sent periodically on the bus). After the information query is completed, the query information follows the same link, that is, the second device-first device-cloud platform-terminal device, to complete the information transmission and query process. During the entire information query process, since the information to be queried is stored in multiple ECUs respectively, it is necessary to wake up multiple ECUs at the same time. The power consumption after ECU wakes up is usually several to dozens of times that before wakeup, and it takes a certain amount of time for ECU to go back to sleep from wakeup state, which results in additional power consumption, and ultimately reduces the maximum parking time of the vehicle (the time to ensure that the vehicle can start normally), affecting the user experience.

[0010] On the other hand, a method for storing and querying Internet of Vehicles data is provided, including: inputting a query instruction through a mobile terminal, and the mobile terminal outputting a query request in response to the received query instruction; an Internet of Vehicles cloud platform receives the query request output by the mobile terminal, and outputs the query request to a first device on the vehicle side; the first device on the vehicle side obtains a vehicle-side bus status in response to the received query request, and the vehicle-side bus status includes a vehicle-side bus sleep state and a vehicle-side bus wake-up state; the first device on the vehicle side outputs a query result in response to the vehicle-side bus sleep state, and the first device on the vehicle side connects to a second device corresponding to the query request in response to the vehicle-mounted longitudinal wake-up state to obtain the query result; the Internet of Vehicles cloud platform obtains the query result through the first device on the vehicle side, and outputs the query result to the mobile terminal.

The vehicle status information is stored in a centralized manner. Compared with the distributed storage solution, it is not necessary to wake up multiple ECUs and query them at the same time during the query process, which can significantly improve the query efficiency and reduce the query time. Since the vehicle status query and storage functions are integrated in the same in-vehicle ECU, and the ECU (first device) has network access capabilities, the in-vehicle network only needs the first device to participate in the remote vehicle status query stage, which can significantly reduce the power consumption of a single query. Since the queried status information still comes from the in-vehicle ECU, and the bus is awakened, the first device will update the stored information. Compared with the solution of directly accessing the back-end server without passing through the vehicle, the reliability of the queried data is fully guaranteed. The collected information supports encrypted storage, which can ensure the security of sensitive information involving personal information. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to at least partially solve one or more of the above-mentioned problems and other potential problems, an embodiment of the present disclosure proposes a vehicle network data storage and query system, including: a mobile terminal, the mobile terminal is used to receive a query instruction, and the mobile terminal outputs a query request in response to the received query instruction; a vehicle network cloud platform, the vehicle network cloud platform is communicatively connected to the mobile terminal, and the vehicle network cloud platform receives the query request through the mobile terminal; a first device, the first device is arranged on the vehicle side, the first device is communicatively connected to the vehicle side bus, the first device acquires and stores the vehicle side bus signal in real time, the first device is communicatively connected to the vehicle network cloud platform, the first device receives the query request through the vehicle network cloud platform, the first device judges the state of the vehicle side bus in response to the query request, the first device outputs the query result to the vehicle network cloud platform according to the vehicle side bus signal stored by the first device in response to the vehicle side bus sleep state, the first device connects to the second device in response to the vehicle side bus wake-up state to obtain the query result, and outputs the query result to the vehicle network cloud platform, and the second device is the vehicle side device corresponding to the query request.

[0020] Specifically, the mobile terminal is a terminal device including a communication module, a data receiving and processing module, etc., for example, a user terminal such as a mobile phone terminal or a web terminal. The mobile terminal is used to receive a query instruction input by a user, wherein the query instruction is used to query vehicle status information, for example, the vehicle status information includes but is not limited to door status information, window status information, total mileage information, cruising range information, and vehicle alarm information. After receiving the query instruction, the mobile terminal outputs a query request for obtaining the vehicle terminal. In some embodiments, the query request may correspond to one or more vehicle status information.

[0021] The Internet of Vehicles cloud platform adopts the existing cloud computing platform to provide data processing, network communication and data storage for the Internet of Vehicles. The Internet of Vehicles cloud platform is connected to the vehicle end and the mobile end respectively.

[0022] The first device is a vehicle-side device, and the first device is connected to the vehicle-side bus. The vehicle-side bus includes CAN, LIN, Ethernet and other types. The first device obtains vehicle status information in real time when the vehicle-side bus is awakened. The first device stores the vehicle status information in real time so that when the vehicle-side changes from the vehicle-side bus awakened state to the vehicle-side bus sleep state, the stored vehicle status information does not disappear. The vehicle status information obtained and stored by the first device includes but is not limited to door status information, window status information, total mileage information, cruising range information and vehicle alarm information. It can be understood by those skilled in the art that the vehicle status information stored by the first device includes time information, and the time information is used to mark the order of the vehicle status information stored by the first device. The first device can obtain the corresponding vehicle status information when the vehicle changes from the vehicle-side bus awakened state to the vehicle-side bus sleep state according to the time sequence. In another embodiment, the first device is updated by the time of the vehicle status information, replaces the vehicle status information of the previous moment with the current vehicle status information, and stores the updated vehicle status information.

[0023] The first device also determines the state of the vehicle-side bus through the level signal of the vehicle-side bus signal. The first device receives the query request through the Internet of Vehicles cloud platform, and determines the state of the vehicle-side bus after receiving the query request. When the vehicle-side bus is in sleep mode, the vehicle status information of the moment before the vehicle-side bus is in sleep mode is output from the timing of the vehicle status information stored in the first device, that is, the query result corresponding to the query request. The first device outputs the query result to the Internet of Vehicles cloud platform, and the Internet of Vehicles cloud platform returns the query result to the mobile terminal. When the vehicle-side bus is in wake-up mode, the first device connects to the second device corresponding to the query request through the vehicle-side bus, obtains real-time vehicle status information through the second device, that is, the query result corresponding to the query request, the second device outputs the query result to the first device, the first device outputs the query result to the Internet of Vehicles cloud platform, and the Internet of Vehicles cloud platform returns the query result to the mobile terminal.

[0024] The second device is a vehicle-mounted device, such as a door controller, a window controller, etc. When the query request is a request to query the door status information, the second device is the door controller, and the first device is connected to the door controller via the vehicle bus. In another embodiment, the second device is a single control unit (ECU), and the second device updates multiple vehicle status information in real time when the vehicle-side bus is awakened. In response to multiple different query requests, the first device obtains the query result by connecting to the second device.

[0025] In some embodiments, the Internet of Vehicles cloud platform outputs a query task creation signal in response to a query request, the mobile terminal starts a task status query module in response to the query task creation signal, the task status query module outputs a task status query instruction according to a preset period, and the Internet of Vehicles cloud platform outputs a task query status in response to the received task status query instruction.

[0026] Specifically, when the Internet of Vehicles cloud platform outputs the query request to the first device, the Internet of Vehicles cloud platform outputs a query task creation signal to remind the user of the mobile terminal that the query request has been issued. The task status query module of the mobile terminal is used to output the task status query instruction to the Internet of Vehicles cloud platform according to a preset period. When the Internet of Vehicles cloud platform does not return the query result, the Internet of Vehicles cloud platform outputs that the task query is not completed, and the task status query module continues to output the task status query instruction according to the preset period; when the Internet of Vehicles cloud platform returns the query result, the Internet of Vehicles cloud platform outputs that the query task is completed, and the task status query module stops outputting the task status query instruction.

[0027] In some embodiments, the first device includes: a bus signal transceiver module, the bus signal transceiver module is used to connect to the vehicle-side bus, and the bus signal transceiver module obtains vehicle status information in real time through the vehicle-side bus; a storage module, the storage module is used to store the vehicle status information obtained by the bus signal transceiver module; a network management module, the network management module is connected to the vehicle-side bus, and the network management module is used to judge the vehicle-side bus status according to the vehicle-side bus signal; a core processing module, the core processing module receives a query request, and the first device connects to the network management module in response to the query request to obtain the vehicle-side bus status, the first device outputs the query result to the Internet of Vehicles cloud platform according to the vehicle-side bus information of the storage module in response to the vehicle-side bus sleep state, the first device connects to the second device through the bus signal transceiver module in response to the vehicle-side bus wake-up state to obtain the query result, and outputs the query result to the Internet of Vehicles cloud platform; a wireless communication module, the wireless communication module is used to connect the core processing module and the Internet of Vehicles cloud platform.

[0028] Specifically, Figure 1As shown, the bus signal transceiver module includes various bus transceivers (typical types include CAN, LIN, and Ethernet), which mainly work at the physical layer, receive vehicle bus signals, and send them to the core processing module for further processing. The storage module uses a NAND type non-volatile memory (eMMC) to centrally store vehicle status information. When the vehicle-side bus is in a sleep state, after the first device receives a vehicle status information query request, it directly accesses the storage module to query the information, and does not wake up the vehicle-side bus during the query. The network management module coordinates the management of multiple types of bus networks and is used to determine the sleep and wake-up conditions of the bus network. The core processing module uses an electronic control unit (ECU) to realize functions such as data reception, data processing, and control. The core processing module receives query requests through the wireless communication module and sends vehicle query results. In some embodiments, external query requests can be received through data communication and text messages.

[0029] In some embodiments, the first device further includes a navigation and positioning module, the navigation and positioning module is used to receive satellite signals, and the core processing module is communicatively connected to the navigation and positioning module.

[0030] Specifically, Figure 1 As shown, the navigation positioning module is used to obtain vehicle location information. When the query request includes vehicle location information, the core processing module wakes up the navigation positioning module and outputs the vehicle location information obtained by the navigation positioning module as the query result.

[0031] In some embodiments, the first device further includes a power module, and the power module is used to supply power to the first device. Figure 1 As shown, the power module independently supplies power to the first device, which can ensure that the first device does not rely on the vehicle body for power supply.

[0032] In some embodiments, the first device further includes a backup power supply, which is activated in response to a power module failure signal, and is used to supply power to the first device. Figure 1 As shown, the backup power supply is used to supply power to the first device when the power module is abnormal.

[0033] In some embodiments, the first device further includes a hardware encryption module, which is used to encrypt and decrypt the storage information and output information of the first device. Figure 1 As shown, the hardware encryption module uses a dedicated hardware device of the existing technology to protect sensitive data, increase the efficiency of encryption and decryption, and can also create, store and manage digital keys.

[0034] On the other hand, a method for storing and querying data in an Internet of Vehicles is provided, including: inputting a query instruction through a mobile terminal, the mobile terminal outputting a query request in response to the received query instruction; the Internet of Vehicles cloud platform receives the query request output by the mobile terminal, and outputs the query request to the first device on the vehicle side; the first device on the vehicle side obtains the vehicle side bus status in response to the received query request, and the vehicle side bus status includes the vehicle side bus sleep state and the vehicle side bus wake-up state; the first device on the vehicle side outputs a query result in response to the vehicle side bus sleep state, and the first device on the vehicle side connects to the second device corresponding to the query request in response to the vehicle longitudinal wake-up state to obtain the query result; the Internet of Vehicles cloud platform obtains the query result through the first device on the vehicle side, and outputs the query result to the mobile terminal. In some embodiments, the Internet of Vehicles cloud platform outputs a query task creation signal in response to the query request, the mobile terminal starts the task status query module in response to the query task creation signal, the task status query module outputs the task status query instruction according to the preset period, and the Internet of Vehicles cloud platform outputs the task query status in response to the received task status query instruction.

[0035] Specifically, the first device includes a bus signal transceiver module, a storage module, a network management module, a core processing module and a wireless communication module. The bus signal transceiver module is used to connect to the vehicle-side bus, and the bus signal transceiver module obtains vehicle status information in real time through the vehicle-side bus; the storage module is used to store the vehicle status information obtained by the bus signal transceiver module; the network management module is connected to the vehicle-side bus, and the network management module is used to judge the vehicle-side bus status according to the vehicle-side bus signal; the core processing module receives a query request, and the first device connects to the network management module in response to the query request to obtain the vehicle-side bus status, and the first device outputs the query result to the Internet of Vehicles cloud platform according to the vehicle-side bus information of the storage module in response to the sleep state of the vehicle-side bus, and the first device connects to the second device through the bus signal transceiver module in response to the wake-up state of the vehicle-side bus to obtain the query result, and outputs the query result to the Internet of Vehicles cloud platform; the wireless communication module is used to connect the core processing module and the Internet of Vehicles cloud platform.

[0036] like Figure 2As shown, when the vehicle-side bus is in sleep mode, the user initiates a vehicle status information query request. The mobile terminal issues an input query command, and the mobile terminal outputs a query request in response to the received query command. After the Internet of Vehicles cloud platform receives the request and successfully creates a query task, the Internet of Vehicles cloud platform initiates a vehicle status query request to the vehicle-side. At the same time, the mobile terminal polls the query task status. Before the vehicle status query task is completed, the Internet of Vehicles cloud platform feedbacks that the query task is not completed. The Internet of Vehicles cloud platform receives the query request, and in response to the received query request, outputs the query request to the vehicle-side. At the same time, the mobile terminal polls the query task status. After receiving the information query request, the first device on the vehicle-side accesses the storage module. After the query task is completed, the first device sends the final query result to the mobile terminal (mobile phone or Web terminal) via the Internet of Vehicles cloud platform. When the vehicle-side bus is in sleep mode, after receiving the vehicle status information query request, the first device directly accesses the storage module for information query. During this period, it will not request the second device to query information, and thus will not wake up the vehicle-side bus, thereby reducing the power consumption during a single query.

[0037] When the vehicle-side bus is in the awakened state, the mobile terminal initiates a remote vehicle status query request. Similar to the query process in the bus sleep state, after the Internet of Vehicles cloud platform receives the vehicle status query request and successfully creates a vehicle status query task, it will send the query request to the first device. At the same time, after receiving the notification of successful creation of the query task, the mobile terminal polls the task status. Before the query task is completed, the Internet of Vehicles cloud platform will feedback to the mobile terminal that the query task is still in progress. After the first device receives the vehicle status query request, if it is determined that the current state is the vehicle-side bus awakened state, since the vehicle status queried in the vehicle-side bus awakened state may change, the first device will access the second device through the vehicle-side bus to obtain updated status information, and then send it to the mobile terminal (mobile phone or Web terminal) via the Internet of Vehicles cloud platform, and finally complete the entire query process.

[0038] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or technical improvements in the market, or to enable other persons of ordinary skill in the art to understand the present invention.
