Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0065] In order to better understand the technical solution of the present invention, the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0066] It should be understood that the embodiments described are only a portion of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative work are within the scope of protection of the present invention.

[0067] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The singular forms "a", "an", "the" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0068] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0069] It should be understood that although the terms first, second, third, etc. may be used to describe numbers in embodiments of the present invention, these numbers should not be limited to these terms. These terms are merely used to distinguish numbers from each other. For example, a first number may also be referred to as a second number, and similarly, a second number may also be referred to as a first number without departing from the scope of embodiments of the present invention.

[0070] The word "if," as used herein, may be interpreted as "at the time of" or "when" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrases "if it is determined" or "if (stated condition or event) is detected" may be interpreted as "when it is determined" or "in response to the determination" or "when detecting (stated condition or event)" or "in response to detecting (stated condition or event)," depending on the context.

[0071] Currently, there are two main communication architecture technologies for the Internet of Vehicles (IoV). The first option is to add an independent telematics box (TBOX) communication module to the vehicle. The TBOX is equipped with communication methods such as the fourth generation mobile communication technology (4G), the fifth generation mobile communication technology (5G), Bluetooth, wireless internet (WIFI), controller area network (CAN), and Ethernet. Pre-installed and after-installed devices can connect to the TBOX through remote, near-field, and wired methods to achieve in-vehicle and out-of-vehicle communication. However, this solution places high demands on the communication integration and information security of the TBOX communication module, resulting in higher costs and increased difficulty in ensuring the stability and reliability of the TBOX communication module.

[0072] The second solution is to integrate various communication technologies into the in-vehicle entertainment system (such as the car computer, smart cockpit, etc.). However, compared with the first solution, this solution has a higher degree of system integration and higher cost. It is not suitable for sharing with multiple vehicle platforms, cannot achieve plug-and-play of IoT devices, and is more difficult to analyze after-sales problems.

[0073] In order to enable a vehicle to achieve secure communication connection with an IOT device and enable plug-and-play of the IOT device, an embodiment of the present invention provides a vehicle, Figure 1 A schematic diagram of a vehicle provided in an embodiment of the present invention is shown as follows: Figure 1 As shown, the vehicle 1 includes an in-vehicle communication module 2, an out-vehicle remote communication module 3, and an in-vehicle near-field communication module 4. The in-vehicle communication module 2 and the out-vehicle remote communication module 3 are connected to each other via a wired communication mode; the out-vehicle remote communication module 3 and the in-vehicle near-field communication module 4 are connected to each other via a wired communication mode.

[0074] In an embodiment of the present invention, the vehicle includes a new energy vehicle. The in-vehicle near-field communication module 4 includes an IoT device. The off-vehicle remote communication module 3 can control the in-vehicle near-field communication module 4 to control the IoT device; the in-vehicle communication module 2 can control the in-vehicle near-field communication module 4 through the off-vehicle remote communication module 3 to control the IoT device. The in-vehicle communication module 2 can authenticate signals sent by or to the in-vehicle near-field communication module 4, confirming that the signals sent by or to the in-vehicle near-field communication module 4 are safe and legal, thereby ensuring the safety of the in-vehicle module.

[0075] The off-board remote communication module 3 is connected to the cloud device 5 via wireless communication. The cloud device 5 includes a base station, a control cloud device, an IoT cloud device, etc. The cloud device 5 can control the vehicle through the off-board remote communication module 3, thereby controlling the IoT devices and the in-vehicle communication module 2. The cloud device 5 can control the vehicle by sending signals. The off-board remote communication module 3 can authenticate the signals sent by the cloud device 5 to confirm that the signals sent by the cloud device 5 are safe and legal, preventing unsafe commands transmitted from the cloud from directly controlling the various modules of the vehicle, thereby protecting the safety of the modules inside the vehicle. The in-vehicle near-field communication module 4 is connected to the user device 6 via wireless and / or wired communication. The user device 6 includes but is not limited to a mobile phone, a tablet computer, a portable PC, a desktop computer, a wearable device, etc. The user device 6 can control the IoT devices by sending signals. The in-vehicle near-field communication module 4 authenticates the signals sent by the user device 6 to ensure that the signals sent by the user device 6 are safe and legal, thereby protecting the safety of the IoT devices. Thus, multiple authentication ports are provided to ensure the security of in-vehicle and out-vehicle communications.

[0076] like Figure 1 As shown, a solid line indicates a wired communication connection, and a dotted line indicates a wireless communication connection. Figure 1 The figure only shows one connection method between the in-vehicle near-field communication module 4 and the user device 6, wherein the in-vehicle near-field communication module 4 and the user device 6 can be connected by wired communication and / or wireless communication; that is, the in-vehicle near-field communication module 4 and the user device 6 can be connected by wired communication; or, the in-vehicle near-field communication module 4 and the user device 6 can be connected by wireless communication; or, the in-vehicle near-field communication module 4 and the user device 6 can be connected by wired communication and wireless communication. When the in-vehicle near-field communication module 4 and the user device 6 are connected by wired communication and wireless communication, since the signal transmission rate of the wired communication is generally higher than that of the wireless communication, the wired communication is preferably used for signal transmission between the modules, thereby improving the signal transmission rate.

[0077] The off-vehicle remote communication module 3 enables remote communication between the cloud device 5 and the vehicle 1, while the in-vehicle near-field communication module 4 enables near-field and / or wired communication between the user device 6 and the vehicle 1. The in-vehicle communication module 2, the off-vehicle remote communication module 3, and the in-vehicle near-field communication module 4 jointly enable communication between the in-vehicle modules, reducing the integration level of the TBOX or in-vehicle entertainment system, reducing design redundancy, and reducing storage usage. Using a distributed functional design, the in-vehicle communication module 2, the off-vehicle remote communication module 3, and the in-vehicle near-field communication module 4 can all authenticate signals, ensuring communication security. The in-vehicle near-field communication module 4 includes an IoT device, enabling plug-and-play use of IoT devices. The in-vehicle communication module 2, the off-vehicle remote communication module 3, and the in-vehicle near-field communication module 4 are all inherent modules within the vehicle and are inexpensive to purchase separately, reducing the cost of enabling secure communication connections between the vehicle and IoT devices and enabling plug-and-play use of IoT devices.

[0078] An embodiment of the present invention provides a vehicle, which includes an in-vehicle communication module, an out-vehicle remote communication module and an in-vehicle near-field communication module; the in-vehicle communication module and the out-vehicle remote communication module are connected to each other through a wired communication method; the out-vehicle remote communication module and the in-vehicle near-field communication module are connected to each other through a wired communication method, and a distributed functional design method is adopted to achieve a high degree of division of labor among each module. The in-vehicle communication module, the out-vehicle remote communication module and the in-vehicle near-field communication module jointly realize the communication between the in-vehicle and the outside of the vehicle, and ensure the transmission efficiency, reduce the integration of the modules, optimize the load of each wiring harness, controller connection and processing, reduce design redundancy, and ensure communication security through authentication, realize plug-and-play of IOT devices, and reduce implementation costs.

[0079] In a possible implementation, the in-vehicle communication module 2 includes an on-vehicle gateway module 21 and a decision module 22 , and the on-vehicle gateway module 21 and the decision module 22 are communicatively connected via a wired manner.

[0080] In the embodiment of the present invention, the decision module 22 includes an electronic control unit (ECU) module 23 and / or a domain controller module 24. The electronic control unit (ECU) module 23 includes at least one in-vehicle ECU, and the at least one in-vehicle ECU is connected to the in-vehicle gateway module 21.

[0081] The in-vehicle communication module 2 is configured to generate a first processing result based on the acquired domain controller signal through a pre-established control decision. Alternatively, the in-vehicle communication module 2 is configured to send the domain controller signal to the off-vehicle remote communication module 3 through a control decision; the off-vehicle remote communication module 3 is configured to generate a second processing result based on the domain controller signal through a control decision; the second processing result is sent to the in-vehicle communication module 2; and the in-vehicle communication module 2 is further configured to receive the second processing result. Alternatively, the in-vehicle communication module 2 is configured to send the domain controller signal to the off-vehicle remote communication module 3 through a control decision; the off-vehicle remote communication module 3 is configured to send the domain controller signal to the in-vehicle near-field communication module 4 through a control decision; the in-vehicle near-field communication module 4 is configured to generate a third processing result based on the domain controller signal through a control decision; the third processing result is sent to the off-vehicle remote communication module 3; the off-vehicle remote communication module 3 is further configured to send the third processing result to the in-vehicle communication module 2; and the in-vehicle communication module 2 is further configured to receive the second processing result. The pre-established control decision includes functions that can be performed by different pre-divided modules.

[0082] The domain controller module 24 includes a domain controller 24. The domain controller can send a domain controller signal to the vehicle gateway module 21. The vehicle gateway module 21 can generate a first processing result based on the domain controller signal sent by the domain controller 24 through a pre-established control decision, wherein the pre-established control decision includes pre-defined functions that can be performed by different modules; and send the first processing result to the domain controller 24. Alternatively, the vehicle gateway module 21 can send the domain controller signal sent by the domain controller 24 to the off-vehicle remote communication module 3 through a control decision; the off-vehicle remote communication module 3 can generate a second processing result based on the domain controller signal through a control decision; and send the second processing result to the vehicle gateway module; the vehicle gateway module 21 is further configured to send the second processing result to the domain controller 24. Alternatively, the onboard gateway module 21, through control decisions, transmits the domain controller signal sent by the domain controller 24 to the off-vehicle remote communication module 3; the off-vehicle remote communication module 3, through control decisions, transmits the domain controller signal to the on-vehicle near-field communication module 4; the on-vehicle near-field communication module 4, through control decisions, generates a third processing result based on the domain controller signal and transmits the third processing result to the off-vehicle remote communication module 3; the off-vehicle remote communication module 3 is further configured to transmit the third processing result to the onboard gateway module 21; and the on-vehicle gateway module 21 is further configured to transmit the second processing result to the domain controller 24. Thus, the onboard gateway module 21, the off-vehicle remote communication module 3, or the on-vehicle near-field communication module 4 can control the domain controller based on the control decisions, reducing the module integration.

[0083] In a possible implementation, the off-vehicle remote communication module 3 includes a wireless communication terminal 31 .

[0084] In this embodiment of the present invention, the wireless communication terminal includes a TBOX. The wireless communication terminal 31 is wirelessly connected to the cloud device.

The IOT device 42 includes at least one IOT peripheral device 420. If the vehicle includes multiple IOT gateway modules 41, each IOT gateway module 41 may be connected to at least one IOT peripheral device 420. When the vehicle includes multiple IOT gateway modules 41, the multiple IOT gateway modules 41 may be distributed at different locations of the vehicle, and the IOT gateway module 41 may serve as a small domain controller to control the IOT peripheral device 420 connected to the IOT gateway module 41. When the IOT gateway module 41 and the IOT device 42 are connected to each other through wired and wireless communication, since the signal transmission rate of the wired method is generally higher than the signal transmission rate of the wireless method, the wired method is preferably used for inter-module signal transmission, thereby improving the signal transmission rate.

[0087] The IOT gateway module 41 includes a large screen for the vehicle. The IOT peripheral devices 420 include a vehicle system, a smart speaker, a smart key, a smart fragrance, a child seat, a refrigerator, a coffee machine, or a humidifier, etc. The embodiments of the present invention do not limit the IOT peripheral devices 420.
