[0042] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0043] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed types.

[0045] With the development of intelligent networking and V2X-related industry chains, the models of various OEMs are gradually equipped with vehicle V2X modules. V2X technology (Vehicle to Everything) refers to the wireless communication between the vehicle and the outside world, and X represents any object that interacts with the vehicle. The V2X system allows the vehicle to communicate with almost all detectable objects to improve the safety, comfort and convenience of the vehicle.

[0046] For example, the system can acquire data from millimeter-wave radars, cameras, ultrasonic sensors, and lidar deployed on the roadside, or perception data from surrounding vehicles equipped with V2X systems, to support functions such as collision avoidance. In a V2X scenario, vehicles can receive wireless transmissions from other moving vehicles, traffic lights, weather reporting networks, and even from cyclists and pedestrians to better understand and interact with the world around them.

[0047] However, since the vehicle's V2X module needs to communicate with road-side equipment and V2X vehicles with V2X, in order to ensure normal communication of vehicles with V2X modules and improve vehicle safety during driving, V2X needs to be tested when the vehicle is offline.

[0048] Therefore, the purpose of the present invention is to provide a method, device, storage medium and equipment for detecting vehicle wireless communication offline, aiming to detect vehicle wireless communication when the vehicle is offline to improve the safety of the vehicle when driving.

[0049] The following embodiments can be applied to Figure 1 In the vehicle wireless communication detection system shown, Figure 1 The structure shown is a vehicle wireless communication detection system provided in an embodiment of the present invention, a vehicle wireless communication road-end device, a vehicle wireless communication certificate platform, an offline device and a vehicle wireless communication module connected in communication, wherein:

[0050] In practice, the V2X road-side device is the object that interacts with the vehicle's on-vehicle wireless communication module. The V2X road-side device is responsible for broadcasting detection information. The on-vehicle wireless communication module receives the detection information broadcast by the road-side device and responds accordingly. The offline device is responsible for writing the VIN code of the offline vehicle, and the V2X certificate platform is responsible for issuing certificates to the on-vehicle wireless communication module.

[0051] It should be pointed out that Figure 1 The structure shown does not constitute a limitation on the vehicle wireless communication detection system. In other embodiments, the vehicle wireless communication detection system may include fewer or more components than shown in the figure, or combine certain components, or arrange the components differently.

[0052] The following will describe in detail how to detect vehicle wireless communication when a vehicle is offline to improve the safety of the vehicle while it is driving, in conjunction with specific embodiments and drawings.

[0053] Embodiment 1

[0054] See also Figure 2 , which shows a vehicle wireless communication offline detection method in a first embodiment of the present invention, and the method includes steps S10 to S12.

[0055] Step S10, when the vehicle is in the awake state, the offline device writes the VIN code into the vehicle controller of the vehicle.

[0056] Among them, the VIN code is the Vehicle Identification Number (Vehicle Identification Number, or frame number), abbreviated as VIN, which is a group of seventeen letters or numbers, a unique number used on the car, which can identify the car's manufacturer, engine, chassis serial number and other performance information. It is the only identification information on the vehicle. The corresponding vehicle can be found through the VIN code. Specifically, after the battery is installed in the vehicle and the whole vehicle is in the awake state, the VIN code is written into the vehicle through the offline equipment to facilitate the acquisition of the corresponding vehicle information through the VIN code. More specifically, the VIN code is mainly carried by the controller in the vehicle, which is usually the vehicle controller.

[0057] Step S11 , the vehicle wireless communication module activates the wireless communication function of the vehicle wireless communication module after receiving the VIN code broadcast by the vehicle.

[0058] Specifically, the vehicle broadcasts the VIN code through the in-vehicle bus so that the vehicle wireless communication module can obtain the VIN code, wherein the in-vehicle bus includes but is not limited to the CAN bus, the LIN bus, and the VAN bus. After obtaining the valid VIN code, in order to detect the vehicle wireless communication module, the vehicle wireless communication module needs to be activated so that the vehicle wireless communication module can be detected normally.

[0059] Step S12, the vehicle wireless communication module receives the test signal broadcast by the vehicle wireless communication road-end device in real time, and obtains a corresponding test response according to the test signal.

[0060] Among them, after the vehicle wireless communication module is activated, the vehicle wireless communication road-end equipment broadcasts a test signal for testing the vehicle wireless communication, simulating the actual interaction between the vehicle wireless communication module and the outside world, and detecting whether the vehicle wireless communication module can send and receive signals normally and whether it can send and receive signals accurately. Therefore, the vehicle wireless communication module can obtain a corresponding test response according to the test signal to determine whether the wireless communication module can send and receive signals normally and whether it can send and receive signals accurately.

[0061] For example, the vehicle wireless communication road-end device is controlled to broadcast green light information in real time. The vehicle wireless communication module receives the green light information signal broadcast by the vehicle wireless communication road-end device and makes a corresponding response. That is, after receiving the signal, it is parsed to find out that the wireless communication road-end device has sent out the green light information. By determining whether the obtained test response matches the information broadcast by the vehicle wireless communication road-end device, it is possible to detect whether the current vehicle wireless communication is normal.

[0062] In addition, the above is only a specific implementation of the present invention, which is only for the purpose of facilitating the understanding of the test signal, the test response and the process of vehicle wireless communication offline detection, and is not intended to limit the present invention.

[0063] In summary, the vehicle wireless communication offline detection method in the above-mentioned embodiment of the present invention simulates the actual vehicle wireless communication scenario by setting the wireless communication road-side equipment, and makes a corresponding test response according to the test signal broadcast by the received vehicle wireless communication road-side equipment, and matches the test response with the information broadcast in real time by the wireless communication road-side equipment to determine whether the vehicle wireless communication is normal. The present invention ensures the normal communication of the vehicle with the V2X module and improves the safety of the vehicle during driving by detecting the vehicle wireless communication when the vehicle is offline.

[0064] Embodiment 2

[0065] See also Figure 3 , which shows a vehicle wireless communication offline detection method in a second embodiment of the present invention, and the method includes steps S20 to S24.

[0066] Step S20, when the vehicle is in the awake state, the offline device writes the VIN code into the vehicle controller of the vehicle.

[0067] Step S21 , the vehicle wireless communication module activates the wireless communication function of the vehicle wireless communication module after receiving the VIN code broadcast by the vehicle.

[0068] Step S22, the vehicle wireless communication certificate platform obtains the VIN code sent by the vehicle wireless communication module;

[0069] In order to improve the security during vehicle wireless communication detection, before the vehicle wireless communication module interacts with the vehicle wireless communication road-end device, the detected vehicle is security authenticated. Specifically, the vehicle wireless communication certificate platform obtains the VIN code sent by the vehicle wireless communication module to obtain the corresponding vehicle information, and based on the vehicle information, it can be determined whether the vehicle is an authorized vehicle.

[0070] Step S23, the vehicle wireless communication certificate platform determines whether the vehicle is an authorized vehicle based on the VIN code; if so, execute step S24.

[0071] Among them, the authorized vehicle refers to the vehicle that can perform vehicle wireless communication detection. After the authorized vehicle that can perform vehicle wireless communication detection is determined, the vehicle is marked with the "capable of vehicle wireless communication" logo by issuing a safety certificate.

[0072] In step S24, a security certificate is issued to the vehicle wireless communication module.

[0073] Step S25, the vehicle wireless communication module receives the test signal broadcast by the vehicle wireless communication road-end device in real time, and obtains a corresponding test response according to the test signal.

[0074] In summary, the vehicle wireless communication offline detection method in the above-mentioned embodiment of the present invention simulates the scenario of vehicle wireless communication in reality by setting up wireless communication road-side equipment, and makes a corresponding test response according to the test signal broadcast by the received vehicle wireless communication road-side equipment, and matches the test response with the information broadcast in real time by the wireless communication road-side equipment, so as to judge whether the vehicle wireless communication is normal, and perform security authentication before the interaction between the vehicle wireless communication module and the vehicle wireless communication road-side equipment. This embodiment ensures the normal communication of the vehicle with the V2X module by detecting the vehicle wireless communication when the vehicle is offline, thereby improving the safety of the vehicle during driving and the safety of vehicle wireless communication detection.

[0075] Embodiment 3

[0076] See also Figure 4 , which shows the vehicle wireless communication offline detection proposed in the third embodiment of the present invention, and the method includes steps S30 to S34.

[0077] Step S30, when the vehicle is in the awake state, the offline device writes the VIN code into the vehicle controller of the vehicle.

[0078] Step S31 , the vehicle wireless communication module activates the wireless communication function of the vehicle wireless communication module after receiving the VIN code broadcast by the vehicle.

[0079] Step S32: the vehicle wireless communication module receives the test signal broadcast by the vehicle wireless communication road-end device in real time, and obtains a corresponding test response according to the test signal.

[0080] Step S33: when it is determined that the test response of the vehicle meets the preset response, the vehicle wireless communication module clears the detection mark.

[0081] Among them, the vehicle wireless communication module is provided with a detection mark, specifically, the detection mark is fault information. In the initial vehicle wireless communication module, that is, the vehicle wireless communication module that has not performed communication detection, a vehicle wireless communication communication fault information is set by default. In real time, it can be implemented by setting a fault code. After the vehicle wireless communication detection of the vehicle passes, the fault code is cleared to indicate that the current vehicle has passed the detection.

[0082] Step S34, the offline device detects the detection mark in the vehicle wireless communication module and determines whether the vehicle wireless communication module contains the detection mark. If not, execute step S35, and if so, execute step S36.

[0083] In order to further improve the quality of vehicle wireless communication detection and prevent vehicles that have not passed the detection from entering the market, after clearing the detection mark in the vehicle wireless communication module, the detection mark in the vehicle wireless communication module is detected by the offline equipment, and it is determined whether the vehicle wireless communication module contains the detection mark. When it is determined that the vehicle wireless communication module contains the detection mark, it indicates that the vehicle wireless communication detection of the current vehicle has passed. When it is determined that the vehicle wireless communication module contains the detection mark, it indicates that the vehicle wireless communication detection of the current vehicle has failed.

[0084] Step S35, issuing a first prompt message, wherein the first prompt message is used to prompt the operator that the vehicle wireless communication module has passed the detection.

[0085] Correspondingly, the offline device is responsible for reading the fault information of the offline vehicle. If there is a fault, it means that the vehicle wireless communication module test has failed. If there is no fault, it means that the vehicle wireless communication module test has passed. Specifically, the prompt information can be given through voice broadcast or screen display. For example, an indicator light or an indication interface is provided on the offline device. If there is a fault, the indicator light or indication interface is red. If there is no fault, the fault indicator light or indication interface is green.

[0086] Step S36, issuing a second prompt message, wherein the second prompt message is used to prompt the operator that the vehicle wireless communication module test has failed, and sending the VIN code to the user.

[0087] When the test fails, the VIN code can be sent to the user so that the user can make statistics on the current vehicle.

[0088] In summary, the vehicle wireless communication offline detection method in the above-mentioned embodiment of the present invention simulates the actual vehicle wireless communication scenario by setting the wireless communication road-side equipment, and makes a corresponding test response according to the test signal broadcast by the received vehicle wireless communication road-side equipment, and matches the test response with the information broadcast in real time by the wireless communication road-side equipment, so as to judge whether the vehicle wireless communication is normal, and detect the detection mark indicating whether the detection is completed after the vehicle detection is completed. This embodiment ensures the normal communication of the vehicle with the V2X module by detecting the vehicle wireless communication when the vehicle is offline, thereby improving the safety of the vehicle during driving and the quality of the vehicle wireless communication detection.
