It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments may be combined with each other.

[0038] In the following description, many specific details are set forth in order to fully understand the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all the embodiments.

[0039] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "comprising a..." does not exclude the existence of additional identical elements in the process, method, article or device including the element.

[0040] In the field of intelligent transportation systems, information exchange between vehicles mainly relies on in-vehicle interconnection communication systems. These systems include multiple sensors and dedicated communication devices installed on vehicles and need to communicate through wireless networks. However, this vehicle-to-vehicle communication method has limitations. For example, affected by network coverage and signal interference, information transmission is unstable and discontinuous under bad weather conditions, and cannot meet the requirements of autonomous driving.

[0041] To solve the problems of the prior art, an embodiment of the present application provides an interactive vehicle communication system, an intelligent road test device and a method. First, the interactive vehicle communication system provided by the embodiment of the present application will be introduced below.

[0042] Figure 1 The structural schematic diagram of the interactive vehicle communication system provided by the first embodiment of the present application is shown. As Figure 1 shown, the system includes:

[0043] A vehicle-mounted camera 11, configured to acquire one or several types of information including natural information, environmental information, and / or traffic information, where the natural information includes at least the road surface smoothness, the environmental information includes at least the visibility, and the traffic information includes at least the vehicle congestion degree;

[0044] A vehicle-mounted lamp assembly 12, including a multi-light source combination module 122 and a visible light sub-module 121, where the visible light sub-module 121 is configured to acquire the vehicle information of the current vehicle and control the multi-light source combination module 122 to emit visible light signals, and the vehicle information includes at least the vehicle speed information and the steering information;

[0045] A vehicle-mounted optical signal receiving module 13, configured to receive the visible light signals emitted by surrounding vehicles, and generate a first driving reference information in combination with the information acquired by the vehicle-mounted camera 11.

[0046] Specifically, the vehicle-mounted camera 11 may only acquire one type of natural information, environmental information, or traffic information, may acquire two of natural information, environmental information, or traffic information, or may acquire natural information, environmental information, and traffic information, which is selected according to the actual situation. In addition to the above information, the vehicle-mounted camera 11 may also acquire other information, and is not limited thereto.

[0047] The natural information mainly refers to the road condition such as the road surface smoothness, such as whether there is snow or rain on the road surface, whether there are bumps on the road surface, and whether there is a slope change on the road surface; the environmental information mainly refers to the visibility of the environment where the current vehicle is located, such as the environmental brightness and the atmospheric haze degree, and the environmental brightness such as day or night; the traffic information mainly refers to the vehicle congestion degree of the section where the current vehicle is located, such as the distance between vehicles and the occurrence of vehicle traffic accidents.

[0048] The vehicle-mounted lamp assembly 12 includes a multi-light-source combined module 122 and a visible photon module 121. The multi-light-source combined module 122 refers to a module in which multiple light sources capable of emitting visible light signals on the vehicle work jointly. Compared with a visible light signal emitted by a single light source, the mode of multiple light sources working jointly can increase the redundancy and reliability of communication. In a specific embodiment, the multiple light sources include two or more of reverse lights, license plate lights, brake lights, tail lights, turn signals, or outline lights. Through the combined control of reverse lights, license plate lights, brake lights, tail lights, turn signals, and outline lights, all information is included in the visible light signals emitted by these light sources, so that in bad weather, surrounding vehicles can obtain all information even when only receiving partial light signals;

[0049] The visible photon module 121 can obtain the vehicle information of the current vehicle, where the vehicle information at least includes vehicle speed information and steering information, and may also include the fault information of the vehicle. The visible photon module 121 converts the vehicle information into a visible light signal and emits it;

[0050] And there is a vehicle-mounted optical signal receiving module 13 on the current vehicle. The vehicle-mounted optical signal receiving module 13 can receive the visible light signals emitted by other surrounding vehicles, convert the received light into a voltage signal through a photoelectric converter, and then be processed by the microcontroller of the vehicle-mounted optical signal receiving module 13. After obtaining specific information, it is transmitted to the driver or the automatic driving control system, and combined with the information obtained by the vehicle-mounted camera 11 as the first driving reference information.

[0051] In this way, efficient information exchange between vehicles can be achieved.

[0052] As Figure 2 shown, in an embodiment, the system further includes an intelligent road test device 14. The intelligent road test device 14 includes a road optical signal transceiver module 141; the vehicle-mounted lamp assembly 12 further includes an invisible photon module 123121. The invisible photon module 123121 is used to control the multi-light-source combined module 122 to emit invisible light signals after obtaining the information in the vehicle-mounted camera 11;

[0053] The road optical signal transceiver module 141 is used to receive the invisible light signals and send the invisible light signals.

[0054] Specifically, the invisible photon module 123121 converts the natural information, environmental information, and / or traffic information obtained by the vehicle-mounted camera 11 into invisible light signals and sends them to the intelligent road test device 14 around the road traffic, and finally aggregates in the upper-layer network space, so that the traffic information of the current road section can be continuously updated by the traffic bureau. Optionally, the invisible light signal is an invisible light signal in the infrared band.

[0055] The intelligent road test device 14 is equipped with a road lighting optical signal transceiver module 141, which can receive and transmit invisible optical signals and analyze the invisible optical signals.

[0056] Optionally, the intelligent road test device 14 further includes a camera or a radar, which can acquire and process natural information, environmental information, and / or traffic information of the current road section, further enhancing the perception ability of various information, thereby improving the accuracy of information reception and the efficiency of traffic management. In extreme weather, it works in cooperation with the in-vehicle camera 11 of the current vehicle, and triggers the multi-light source combination module 122 to emit light rays with different wavelengths and light intensities through the transceiver of invisible optical signals, or realizes real-time transmission of information through wireless communication technologies such as dedicated short-range communication (DSRC).

[0057] Optionally, the invisible optical signal emitted by the intelligent road test device 14 can also be received by the in-vehicle optical signal receiving module 13 of the current vehicle, which is used to provide the second driving reference information for the driver or autonomous driving.

[0058] In this way, the system effectively solves the problems of traditional wireless communication technologies being restricted by network coverage, high latency, and performance degradation in bad weather, and provides a high-real-time and low-power communication solution for autonomous driving and intelligent traffic management. Through the collaborative work of intelligent roadside devices and vehicles, the system can achieve efficient information exchange between vehicles and between vehicles and infrastructure, significantly improving the safety and traffic efficiency of road traffic. This system provides strong technical support for the further development of intelligent transportation systems and has broad application prospects.

[0059] Such as Figure 3 As shown, in the specific application scenario of this embodiment, the in-vehicle camera 11 includes at least one or several of a natural information recognition sub-module 111, an environmental information recognition sub-module 112, or a traffic information recognition sub-module 113;

[0060] The natural information recognition sub-module 111 is at least used to recognize the smoothness of the road surface; the environmental information recognition sub-module 112 is at least used to recognize visibility, and visibility includes environmental brightness and atmospheric visibility; the traffic information recognition sub-module 113 is at least used to recognize the vehicle congestion degree and traffic accident situation of surrounding vehicles.

[0061] In one embodiment, the multi-light source combination module 122 includes two or more of a reverse light, a license plate light, a brake light, a tail light, a turn signal light, or a contour light, and two or more means two, three, four, five, and six. The communication transmission of visible light signals or invisible light signals is realized by using various different combinations of the vehicle's own reverse light, license plate light, brake light, tail light, turn signal light, and contour light.

[0062] In one embodiment, the system further includes an anti-interference module, which is used to adjust the illumination intensity of the visible light signal output according to the environmental information. By knowing the environmental brightness and the degree of atmospheric haze included in the environmental information, under harsh weather conditions such as rain, fog, and snow, the light wavelength and illumination intensity are dynamically adjusted to enhance the signal penetration and anti-interference ability, so as to achieve the purpose of resisting environmental interference.

[0063] In this embodiment, the intelligent road test device 14 can also trigger the multi-light source combination module 122 to select appropriate wavelengths and illumination intensities, further achieving the purpose of resisting environmental interference.

[0064] In one embodiment, the visible photon module 121 generates a visible light encoded signal by encoding the light color and the light flashing frequency, so as to control the multi-light source combination module 122 to emit a visible light signal.

[0065] Optionally, the light color and the light flashing frequency are arranged and combined so that the visible light encoded signal includes at least one or several signals of emergency braking, left turn, right turn, fault state, excellent road condition, dangerous road condition, vehicle congestion, or traffic accident.

[0066] In a specific application scenario, the light color and the flashing frequency used by the vehicle-mounted lamp assembly 12 are encoded to generate a visible light encoded signal, which is convenient for the transmission of instructions and the surrounding vehicles to parse after receiving the visible light signal.

[0067] Optionally, the light color encoding is defined as follows:

[0068] Red is 011, white is 100, green is 010, blue is 101, and yellow is 001.

[0069] Define the flashing frequency as the number of flashes n per second, which is converted from decimal to binary. For example, if it flashes 7 times per second, the encoding is 111, and at the same time, the upper limit is set to 8 times, and the encoding is 000.

[0070] The multi-light source combination module 122 includes: brake lights, tail lights, turn signals, reverse lights, license plate lights, and outline lights.

[0071] Optionally, the vehicle speed information is transmitted through the tail lights at a specific flashing frequency. For example, the number of flashes per second is multiplied by a base number n (such as n = 1) to obtain an approximate value of the vehicle speed information. To improve the recognition rate, it is recommended to use red light with a longer wavelength for the tail lights because red light has a longer propagation distance and stronger penetration in the air;

[0128] Through the transmission and reception of the above optical signals after encoding, a multi-light-source redundant coding mode and a joint working mode are realized, and the light intensity is dynamically adjusted under extreme weather conditions to ensure the robustness of information transmission. Even when some optical signals are blocked, surrounding vehicles can still receive complete information through redundant light sources, significantly improving the reliability of the system.

[0129] Optionally, the end of the visible light coding signal is a CRC check code, which is used to check errors in the transmission process of the visible light signal and initiate an automatic repeat request. A CRC check code is appended to the end of each coded message to detect errors in the information transmission process. If an error is detected, the receiving end can request the sending end to retransmit the information to ensure the accurate transmission of the information.
