[0030] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0031] Among the related technologies, near-field communication of automobiles can be achieved through technologies such as WLAN (Wireless Local Area Network) or DSRC (Dedicated Short Range Communication). There are relatively few vehicles that integrate and implement these Internet of Vehicles technologies, making them difficult to popularize. In addition, the use of technologies such as radio waves for Internet of Vehicles communication may be affected by signal interference, network delays, etc., resulting in communication errors due to signal loss or interference.

[0032] In order to overcome the problems of high difficulty in popularizing near-field communication through technologies such as WLAN or DSRC, and susceptibility of wireless communication to interference, and to improve the safety and efficiency of the transportation system, the present disclosure provides a vehicle communication method, device, vehicle communication system and vehicle.

[0033] See also Figure 1 , Figure 1 is a flow chart of a vehicle communication method according to an exemplary embodiment. Figure 1 As shown, the vehicle communication method can be applied to a first vehicle, including the following steps.

[0034] In step S101, an optical signal sent by a second vehicle is received by an optical signal receiving module, the second vehicle is a vehicle around the first vehicle, and the optical signal is obtained by the second vehicle based on the driving information and / or driver information of the second vehicle; In step S102, the light signal is analyzed to obtain driving information and / or driver information.

[0035] For example, the first vehicle may be any vehicle in a driving process, and the second vehicle may be any vehicle around the first vehicle. The first vehicle is provided with an optical signal receiving module to receive an optical signal sent by the second vehicle.

[0036] For example, the second vehicle can obtain the driving information and / or driver information of the second vehicle through the intelligent driving system of the second vehicle, wherein the intelligent driving system interacts with sensors on the vehicle to obtain the driving information and / or driver information of the first vehicle.

[0037] For example, the driving information may be the driving data related to the vehicle during the driving process, which can be obtained through the vehicle's own sensors, radars, navigation systems, intelligent driving systems, etc. The driving information may include at least one of the driving information such as vehicle speed, vehicle acceleration, vehicle fault information, vehicle fuel consumption, remaining fuel, mileage, single cruising range, navigation information, driving trajectory, etc. For example, based on the vehicle speed and vehicle acceleration, it can be determined whether the second vehicle is speeding; based on information such as vehicle fault information, it can be determined whether the second vehicle is faulty; based on vehicle fuel consumption, remaining fuel, mileage, single cruising range, etc., it can be determined whether the second vehicle has a deceleration intention or a turning intention. If the cruising range is low, the second vehicle may enter the server for charging and refueling; based on navigation information, driving trajectory, etc., it can be determined whether the second vehicle has a deceleration intention, acceleration intention, turning intention, etc.

[0038] For example, the driver information may be the driver status information of the second vehicle, which may be monitored by a driver monitoring system. For example, the driver status information may include any of the driver's dangerous driving states such as fatigue driving state, angry driving state, suspected drunk driving state, etc., and may also include normal driving state. The driver information may also be shared information input by the driver of the second vehicle in the vehicle system of the second vehicle. For example, the driver of the second vehicle selects shared information on the display screen of the vehicle system of the second vehicle based on the selection operation corresponding to the shared information, such as in a preset shared information list, and determines to send the shared information to the surrounding first vehicles. The second vehicle may send the shared information to the first vehicles around the second vehicle.

[0039] For example, an optical signal is a communication method that uses light waves to transmit information. The optical signal here can use visible light, optical fiber, or invisible light such as infrared to achieve information sharing of driving information and / or driver information between vehicles. In one example, the optical signal can be modulated according to preset modulation rules and driving information. For example, the presence or absence of modulated light, the change of the light source matrix of the modulated light, the intensity of the modulated light, the frequency of the modulated light, the phase of the modulated light, etc. can be modulated. Through at least one of the above optical modulation technologies, the second vehicle can transmit different information to the first vehicle using optical signals in different modulation forms.

[0040] For example, optical signals are subject to less interference during transmission, and compared to radio waves, optical communication can maintain stable transmission quality in complex urban environments or high-density traffic. Therefore, the use of optical signals can help achieve high-speed, low-latency information transmission, improving the efficiency and reliability of inter-vehicle communication.

[0041] For example, the driving information of the first vehicle is sent to the surrounding second vehicle through the light signal, and after the second vehicle receives the light signal, it controls the vehicle according to the received driving information. The second vehicle can adjust the speed, direction or other driving behavior of the second vehicle accordingly according to the driving state information and / or driving intention information of the driver of the first vehicle included in the driving information corresponding to the light signal.

[0042] For example, the first vehicle may parse the optical signal to obtain the driving information and / or driver information shared by the second vehicle. Then, the first vehicle may output corresponding prompt information, driving suggestions, etc. to the driver of the first vehicle based on the driving information and / or driver information of the second vehicle. Alternatively, when the first vehicle is in automatic driving, the first vehicle may also control the first vehicle based on the driving information and / or driver information of the second vehicle, so that the first vehicle automatically avoids the second vehicle when the second vehicle poses a threat to the driving of the first vehicle.

[0043] The present disclosure receives an optical signal sent by a second vehicle through an optical signal receiving module. The second vehicle is a vehicle around the first vehicle, and the optical signal is obtained by the second vehicle based on the driving information and / or driver information of the second vehicle; the optical signal is parsed to obtain the driving information and / or driver information. In this way, the driving information and / or driver information can be transmitted between the first vehicle and the second vehicle through optical signals, thereby realizing data communication and sharing between vehicles. At the same time, the optical signal is less subject to interference during the transmission process. The first vehicle receives the driving information and / or driver information of the second vehicle through optical signals, which enhances the anti-interference ability of vehicle-to-vehicle communication and improves the reliability of driving information transmission.

[0044] As an optional embodiment, the light signal is parsed to obtain driving information and / or driver information, including: According to the preset mapping relationship between the light signal and different information, the driving information and / or the driver information is obtained.

[0045] For example, in the preset mapping relationship, different modulation modes of the optical signal can correspond to different information, wherein an optical signal modulated in a first mode can correspond one-to-one with a piece of information; or an optical signal modulated in a second mode can correspond to multiple pieces of information. The preset mapping relationship can be presented in a table, or the optical signal and different information can be matched and associated through a database.

[0046] For example, the correspondence between different types of information and optical signals can be determined by a general preset mapping relationship. The correspondence between different types of information and optical signals can be determined by respectively corresponding preset mapping relationships, for example, the correspondence between driving information and optical signals is a first mapping relationship, the correspondence between driver information and optical signals is a second mapping relationship, and the correspondence between driving information and driver information and optical signals is a third mapping relationship. It can be understood that different optical signals are optical signals determined by different modulation methods, and optical signals can use visible light or invisible light, which is determined according to actual conditions and is not limited here.

[0047] As an optional embodiment, the driving information and / or driver information is obtained according to a preset mapping relationship between the light signal and different information, including: The driving information and / or driver information corresponding to the light signal is obtained by querying from the preset mapping relationship.

[0048] For example, a preset mapping relationship is pre-stored in the optical analysis module of the first vehicle. When the optical signal receiving module of the first vehicle receives the optical signal sent by the second vehicle, a process of querying corresponding information according to the preset mapping relationship can be automatically triggered.

[0049] For example, the light signal may be matched and associated with the corresponding driving information and / or driver information to form a preset mapping relationship. Then, based on the light signal and the preset mapping relationship, a query may be performed in the preset mapping relationship to determine the information corresponding to the light signal.

[0050] For example, when the optical signal receiving module of the first vehicle receives the optical signal sent by the second vehicle, the system searches for the corresponding driving information and / or driver information in the preset mapping relationship according to the optical signal. Specifically, the system parses the optical signal to obtain the corresponding query identifier, such as a serial number, ID information, etc., and then queries and obtains the corresponding information in the preset mapping relationship based on the query identifier to obtain the driving information and / or driver information corresponding to the optical signal. Correspondingly, when the second vehicle compiles the vehicle, it can also use the preset mapping relationship to modulate the optical signal of the driving information and / or driver information to be transmitted, and obtain the optical signal corresponding to the driving information and / or driver information of the second vehicle for transmitting to the first vehicle. The corresponding method of modulating the optical signal at the second vehicle end can also be based on the query identifier corresponding to the driving information and / or driver information, such as a serial number, ID information, etc., to determine the modulation method of the optical signal, and then obtain the modulated optical signal.

[0051] As an optional embodiment, the method further includes: Prompt information is output to the driver of the first vehicle based on the analyzed driving information and / or driver information.

[0052] For example, the prompt information can be used to prompt the driver of the first vehicle that the second vehicle may be in some danger. For example, the second vehicle has a fault, the driver of the second vehicle is in a dangerous driving state, etc. The prompt information can also be used to prompt the driver of the first vehicle about the possible driving intention of the driver of the second vehicle at the next moment, for example, the driver of the second vehicle will control the vehicle to slow down, stop, turn, accelerate, overtake, etc.

[0053] For example, different driving information and / or different driver information have different corresponding prompt information. In one example, there may be a preset correspondence between the prompt information and the driving information and the driver information. For example, the prompt information includes first prompt information corresponding to different driving information, second prompt information corresponding to different driver information, third prompt information corresponding to different driving information and different driver information, etc. Alternatively, the prompt information may be output according to a neural network. Based on the current driving information and / or driver information, the neural network identifies possible dangerous information, driving intentions, shared information, etc., and outputs prompt information for dangerous information, driving intentions, shared information, etc. For example, through voice broadcast, output information such as "The driver of the vehicle in front may be in an angry driving state, please pay attention to avoid", "The vehicle behind is about to overtake", "The information shared by your friend is received, please check it carefully", etc.

[0054] As an optional embodiment, the driving information includes fault information of the second vehicle, and outputting prompt information to the driver of the first vehicle includes: The prompt information corresponding to the fault information is displayed on a display screen of the first vehicle, and / or the prompt information corresponding to the fault information is broadcast to the driver of the first vehicle through a voice broadcast system.

[0055] For example, the fault information of the second vehicle is generally only displayed to the driver of the second vehicle, and the driver of the first vehicle around the second vehicle may not be aware of the fault of the second vehicle. Therefore, when an unexpected situation occurs, the driver of the first vehicle may not be able to avoid it in time. Therefore, the second vehicle can transmit the fault information of the second vehicle to the first vehicle through an optical signal, so that the first vehicle can output prompt information corresponding to the fault information to the driver of the first vehicle according to the fault information of the second vehicle.

[0056] Here, the prompt information corresponding to the fault information may be a prompt that a fault exists in the second vehicle, or may be a prompt of the fault type corresponding to the second vehicle, for example, "The vehicle in front has a flat tire, be careful to avoid it."

[0057] For example, the prompt information may be displayed on a display screen, or a voice prompt may be outputted through voice broadcasting. For example, when the first vehicle is traveling at a low speed, the prompt information may be displayed on a display screen, or a voice prompt may be outputted through voice broadcasting. When the first vehicle is traveling at a high speed, the prompt information may be displayed on a display screen, and a voice prompt may be outputted through voice broadcasting, so that the driver can easily receive the prompt information during driving.

[0058] As an optional embodiment, the driving information includes dangerous driving information corresponding to the second vehicle and a safety level corresponding to the dangerous driving information, wherein the dangerous driving information is driving information in which the second vehicle affects the driving safety of the first vehicle; Outputting prompt information to the driver of the first vehicle includes: According to the safety level of the dangerous driving information, prompt information for the dangerous driving information is output to the driver of the first vehicle.

[0059] For example, the driving information may include dangerous driving information corresponding to the second vehicle and the safety level corresponding to the dangerous driving information, wherein the dangerous driving information may include any of the following behaviors: speeding, frequent lane changes, rapid acceleration / deceleration of the second vehicle, the second vehicle decelerating and about to have a distance with the surrounding first vehicle less than a safe distance, the second vehicle overtaking, etc. The dangerous driving information may also include fault information of the second vehicle.

[0060] Specifically, the safe distance refers to the necessary distance that the rear vehicle should maintain from the front vehicle in order to avoid an accidental collision with the front vehicle. Different vehicle speeds correspond to different safe distances. Therefore, the current safe distance can be determined by the current speeds of the first vehicle and the second vehicle. According to the current safe distance and the distance between the first vehicle and the second vehicle in front, when the distance is less than the safe distance, there may be a risk of collision.

[0061] Specifically, when the speed of the second vehicle is greater than the maximum speed limit of the current road, it is determined that the second vehicle is speeding; when the speed of the second vehicle represents the acceleration of the vehicle when it is accelerating and is greater than the first acceleration threshold, it is determined that the second vehicle is accelerating rapidly; when the speed of the second vehicle represents the acceleration of the vehicle when it is decelerating and is greater than the second acceleration threshold, it is determined that the second vehicle is decelerating rapidly. Accordingly, the first vehicle can output prompt information for prompting the driver of the vehicle to slow down, change lanes, or stop to avoid the dangerous driving information.

[0062] For example, when the second vehicle determines that there is dangerous driving information in the driving information, it can determine the safety level corresponding to the dangerous driving information based on the dangerous driving information and synchronize it to the first vehicle. The first vehicle can make a corresponding strategy for outputting prompt information based on the safety level.

[0063] For example, the safety level corresponding to the dangerous driving information can be determined by the type of dangerous driving information and the correspondence between different types and safety levels. Alternatively, the safety level of the dangerous driving information can be determined by using a preset scoring rule. Alternatively, the safety level of the dangerous driving information can also be determined by using a neural network, which is not limited here.

[0064] For example, different light signal modulation methods can be determined according to different safety levels and sent to the first vehicle. For example, when the urgency is more complex, the modulation method of the light signal of driving information is more complex, such as modulating the phase of light, the intensity of light, and the frequency of light at the same time, so that the first vehicle can identify the danger in time and slow down or brake in advance; when the urgency is lower, the modulation method of the light signal of driving information is simpler, such as only modulating the phase or light source matrix change to ensure that the second vehicle reduces the waste of computing resources. For example, when the urgency is higher, by modulating the intensity of light, the target light signal can be modulated into a high-visibility visible light source, so that the first vehicle can more easily receive the driving information of the second vehicle and control the vehicle; when the urgency is lower, by modulating the intensity of light, the target light signal can be modulated into a low-visibility light source or no light source to reduce energy waste.

[0065] As an optional embodiment, according to the safety level of the dangerous driving information, outputting prompt information for the dangerous driving information to the driver of the first vehicle includes: When the safety level is higher than the safety level threshold, no prompt information for dangerous driving information is output; When the safety level is lower than or equal to the safety level threshold, prompt information for the dangerous driving information is displayed on the display screen of the first vehicle, and / or prompt information for the dangerous driving information is broadcast to the driver of the first vehicle through a voice broadcast system.

[0066] For example, the safety level threshold can be set according to actual conditions. Among them, when the safety level is higher than the safety level threshold, it can be considered that the dangerous behavior information corresponding to the second vehicle has little impact on the surrounding first vehicle, and the prompt information may not be output. Specifically, for example, the tire of the second vehicle is punctured, the driver of the second vehicle is not wearing a seat belt (the sensor at the seat belt buckle can be identified), the second vehicle is the front vehicle of the first vehicle, and the second vehicle is speeding, etc. The safety level of these dangerous driving information is low, and the first vehicle may not output prompt information. When the safety level is lower than or equal to the safety level threshold, it can be considered that the dangerous behavior information corresponding to the second vehicle has a greater impact on the surrounding first vehicle, and it is necessary to remind the driver of the first vehicle to pay attention to avoidance. For example, the tire of the second vehicle is punctured, the second vehicle behind is about to overtake, the second vehicle in front is about to change lanes, the second vehicle tank is leaking, the second vehicle is about to turn, the second vehicle behind is speeding, etc. The safety level of these dangerous driving information is high, and the safety threat to the first vehicle is greater, and prompt information needs to be output in time to remind the driver of the first vehicle to slow down and avoid.

[0067] In addition, multiple safety level thresholds may be set, and prompt information regarding the dangerous driving information may be output to the driver of the first vehicle according to the safety level of the dangerous driving information. This may also include: when the safety level is higher than the first safety level threshold, no prompt information regarding the dangerous driving information may be output; when the safety level is lower than or equal to the first safety level threshold and higher than the second safety level threshold, prompt information regarding the dangerous driving information may be displayed on the display screen of the first vehicle, and / or prompt information regarding the dangerous driving information may be broadcast to the driver of the first vehicle through a voice broadcast system; when the safety level is lower than or equal to the second safety level threshold and the first vehicle is in automatic driving mode, prompt information regarding the first vehicle being controlled to avoid the second vehicle may be output to the driver of the first vehicle, and the first vehicle may be controlled to avoid the second vehicle.

[0068] Here, the prompt information output by the first vehicle is graded by multiple safety thresholds, and the situation that the first vehicle can automatically avoid the second vehicle is considered when the first vehicle is in the automatic driving mode. Among them, when the safety level is higher than the first safety level threshold, it can be considered that the dangerous behavior information corresponding to the second vehicle has little impact on the surrounding first vehicles. When the safety level is lower than or equal to the first safety level threshold, and higher than the second safety level threshold, it can be considered that the dangerous behavior information corresponding to the second vehicle has a greater impact on the surrounding first vehicles. When the safety level is lower than or equal to the second safety level threshold, it can be considered that the dangerous behavior information corresponding to the second vehicle has a very large impact on the surrounding first vehicles. If in the automatic driving mode, the driver may not have time to exit the self-driving mode and then control the vehicle to avoid. Therefore, the first vehicle can be controlled to avoid according to the dangerous driving information corresponding to the second vehicle.

[0069] As an optional embodiment, the driver information includes driver status information monitored by a driver monitoring system of the second vehicle, and outputting prompt information to the driver of the first vehicle includes: When the driver status information indicates that the driver of the second vehicle has at least one dangerous driving behavior among fatigue driving behavior, angry driving state and suspected drunk driving state, prompt information for the dangerous driving behavior is output to the driver of the first vehicle.

[0070] For example, whether there is dangerous driving behavior in the driver status information can be identified by the first vehicle. At this time, the driver status information of the second vehicle is the original driver status information, such as the in-vehicle image obtained by the camera of the second vehicle. However, since the identification of dangerous driving behavior also involves some private information, such as the driver's portrait, after the second vehicle completes the identification of the driver's dangerous driving behavior, the corresponding dangerous driving behavior can be sent to the first vehicle as driver status information. At this time, the first vehicle does not need to identify it again, but directly outputs prompt information for the dangerous driving behavior to the driver of the first vehicle based on the dangerous driving behavior included in the driver status information. For example, when the driver status information is fatigue driving behavior, the prompt information of "Watch out for fatigue driving of the driver of the vehicle in front" is output; when the driver status information is angry driving behavior, the prompt information of "Watch out for angry driving of the driver of the vehicle in front" is output.

[0071] For example, the driver monitoring system of the second vehicle can monitor the driver's state information in real time, where the driver's state information may include the driver's physiological state (such as heart rate, blood pressure, fatigue level), steering wheel operation, pedal use, concentration, expression, etc. The second vehicle can obtain the driver's expression and behavior through the vehicle-mounted camera and determine the driver's state information.

[0072] For example, the interior image of the second vehicle can be acquired through the interior camera of the second vehicle. Specifically, the interior image frame acquired in real time by the interior camera of the second vehicle can be used as the interior image of the second vehicle, or the image frame in the interior video data stream acquired in real time by the interior camera of the second vehicle can be used as the interior image of the second vehicle. Then, image recognition is performed on the interior image to obtain an image recognition result for characterizing the driving state of the driver of the second vehicle.

[0073] For example, the image recognition of the in-car image can be performed using an existing image recognition algorithm, and the specific image recognition algorithm is not limited here. For example, a neural network such as LBP (Local Binary Pattern) or CNN can be used for image detection or face recognition to determine whether the driver is wearing a seat belt or to detect the driver's facial expression.

[0074] For example, by identifying the driver's facial expression contained in the in-car image, it can be identified whether the driver is in at least one of a fatigue driving state and an angry driving state. For example, when the frequency of fatigue expression appearing in the driver's facial information is greater than a preset frequency, the corresponding driving state information is determined to be a fatigue driving state, wherein the fatigue expression may include at least one of the following facial expressions: blinking, nodding, shaking head, bowing, and yawning. For example, when the duration of an angry expression appearing in the driver's facial information is greater than a preset duration, the corresponding driving state information is determined to be an angry driving state, wherein the angry expression includes at least one of the following facial expressions: staring, frowning, and the like. Accordingly, for the fatigue driving state and the angry driving state, the second vehicle can send the driver state information to the first vehicle, and the first vehicle can output prompt information based on the received driver state information to prompt the driver to slow down or change lanes.

[0075] For example, by identifying the driver's actions contained in the in-car image, it is possible to identify whether the driver is in a suspected drunk driving state. For example, when it is identified that the driver's hands are off the steering wheel for a time longer than a preset time, the driver shakes his head significantly for a time longer than a preset time, and the driver closes his eyes for a time longer than a preset time, the corresponding driving state information is determined to be a suspected drunk driving state. Accordingly, for the suspected drunk driving state, the first vehicle can send a prompt message to the driver of the vehicle to prompt the driver of the vehicle to slow down or change lanes to avoid, or the first vehicle can also send an alarm message to the traffic management department, etc.

[0076] For example, it is also possible to identify whether the driver is not wearing a seat belt by performing seat belt recognition in the in-vehicle image. Existing seat belt recognition algorithms can be used to detect whether the driver and passengers are not wearing seat belts, such as detecting whether a seat belt buckle near the B-pillar of the vehicle exists, or detecting whether the driver and passengers are wearing seat belts.

[0077] For example, the second vehicle can transmit all driver status information to the first vehicle, but in order to ensure the privacy of the driver information, the driver status can be identified by the second vehicle, and it can be determined whether the driver of the second vehicle has at least one dangerous driving behavior among fatigue driving behavior, angry driving state and suspected drunk driving state. When it is determined that at least one dangerous driving behavior among fatigue driving behavior, angry driving state and suspected drunk driving state exists, the second vehicle sends the corresponding driver status information to the first vehicle via a light signal. The first vehicle can determine that the driver of the second vehicle has engaged in dangerous driving behavior based on the driver status information parsed from the light signal, and therefore can output corresponding dangerous driving behavior prompt information.

[0078] As an optional embodiment, the driver information includes shared information input by the driver of the second vehicle in the vehicle system; the optical signal is parsed to obtain the driver information, including: The optical signal is analyzed to obtain shared information.

[0079] For example, when the driver of the second vehicle may be acquainted with the driver of the first vehicle, or the second vehicle and the first vehicle are in a vehicle convoy, or other vehicles may share preset information, shareable information is provided to the driver in the vehicle's on-board system so that the driver can share the shared information with drivers of other vehicles based on the preset shared information in the on-board system.

[0080] For example, the driver of the second vehicle can input the shared information that he wants to share with other drivers of the first vehicle into the vehicle system, and modulate the light based on the shared information to obtain the light signal. Specifically, in the optical signal modulation module of the second vehicle, the shared information can be modulated based on the pre-stored shared information and the mapping relationship between the shared information and the light signal to obtain the light signal. For example, the preset shared information list can be displayed on the display screen of the vehicle system, and in response to the user's selection operation on the shared information in the preset shared information list on the display screen, the vehicle system transmits the shared information to the optical signal modulation module to obtain the light signal corresponding to the shared information.

[0081] In an exemplary scenario, information sharing between the first vehicle and the second vehicle is performed through optical signals to realize fleet networking. For example, based on the second vehicle sending password information corresponding to the wireless communication method to the surrounding first vehicle through optical signals, the first vehicle can then automatically trigger joining the wireless communication network of the corresponding fleet based on the password information, or based on the driver of the first vehicle inputting the password information to the fleet to be joined, to realize joining the wireless communication network of the corresponding fleet. After the fleet is networked, traffic efficiency and safety can be improved through communication and collaboration between vehicles. Ensure simultaneous linkage communication of multiple vehicles and provide users with services such as voice intercom, data communication and image transmission. For example, the command vehicle node can perform video monitoring of the interior, front of the vehicle and road conditions of other vehicles, and can retrieve any video of the fleet, and can also transmit it back to the command center through the satellite system.

[0082] For example, the vehicle can determine the order of the command vehicle node and the remaining vehicles according to a preset rule. Figure 5For example, assume that car A is the command car, and cars B and C are the subsequent vehicles of car A in sequence. Based on the vehicle teaming request triggered by the driver of car B in the car display screen, when car B sends a first optical signal to car A, it requests to join the team. The first optical signal can be a predefined protocol or a specific coded information, which can be used to indicate the request to join the team. Then, car A receives the teaming request corresponding to the first optical signal sent by car B, and car A confirms the teaming request of car B. At the same time, car C also sends a teaming request to car B through the first optical signal. After car B receives the first optical signal of car C, since car B is not the command car, car B forwards the first optical signal of car C to car A, and car A confirms the teaming request of car C. Among them, after the teaming request is transmitted to the command vehicle, the car system of the command vehicle can display a pop-up window for confirming the teaming request on the car screen, and the driver of the command vehicle confirms the teaming request of all vehicles on the car screen of the command vehicle.

[0083] For example, when the command vehicle confirms the requests of all other vehicles, a second optical signal can be sent through a second optical signal to indicate the sharing of networking information such as Wifi passwords, Bluetooth information, or cloud service authentication information. After all other vehicles receive the networking information corresponding to the second optical signal, they are connected to the same wireless transmission network, thus completing the establishment of a communication network within the fleet. Once the internal network of the fleet is established, each vehicle can communicate and collaborate in real time through the network. For example, traffic information such as vehicle location, speed, and estimated arrival time can be shared, traffic control instructions can be transmitted, warnings and emergency measures can be taken in emergency situations, and so on.

[0084] As an optional embodiment, the method further includes: A driving suggestion is output to the driver of the first vehicle based on the analyzed driving information and / or driver information.

[0085] For example, when outputting prompt information based on the parsed driving information and / or driver information, the first vehicle can use machine learning and data analysis technology to process and analyze the collected data to identify potential risks and unsafe driving behaviors. Based on the analysis results, the risks that may be encountered during driving, such as sharp turns, sudden braking, speeding, etc., are evaluated, and the safety level is divided according to the severity of the risk, the possibility of occurrence, and the driver's controllability of the risk. Then, driving suggestions can be output to the driver of the first vehicle, for example, suggesting that the driver change lanes, suggesting that the driver slow down, etc.

[0086] It is understandable that the prompt information and the driving advice do not conflict. When the prompt information is output, the driving advice can also be output. For example, the prompt information "the driver of the vehicle ahead is in a fatigued driving state" and the driving advice "lane change is recommended" are output at the same time. This is only an example and does not limit the specific form of outputting the prompt information and driving advice. For example, the prompt information can be output by voice broadcast, and the driving advice can be output on the vehicle display screen. The prompt information and driving advice can also be broadcast in different broadcasting orders, or the vehicle display screen can be displayed on the vehicle display screen at the same time.

[0087] As an optional embodiment, the method further includes: When the first vehicle is in the automatic driving mode, vehicle control of the first vehicle is performed based on the parsed driving information and / or driver information.

[0088] For example, when the first vehicle is in the automatic driving mode, the first vehicle can control the first vehicle based on the parsed driving information and / or driver information, so that the first vehicle automatically avoids the second vehicle when the second vehicle poses a threat to the driving of the first vehicle.

[0089] For example, the decision system of the automatic driving control system can formulate corresponding strategies and generate corresponding control signals based on the analyzed driving information and / or driver information to control the acceleration, braking and steering of the vehicle. For example, based on the navigation information of the second vehicle, the driver's pedal opening information, the driving trajectory, the steering wheel steering angle light driving information, the driving intention of the second vehicle can be determined, such as the driving intention of the second vehicle to turn or stop, so that the first vehicle can be controlled to slow down and avoid, change lanes and avoid, etc. according to the driving intention of the second vehicle. For example, when the driver's state in the driver information indicates that the driver has at least one dangerous driving behavior of fatigue driving behavior, angry driving state and suspected drunk driving state, the second vehicle is controlled to change lanes and avoid, slow down and avoid, send an alarm signal to the public security equipment, etc.

[0090] In addition, during the vehicle control process, the system will continuously monitor the vehicle's status and changes in the surrounding environment. If deviations or new threats occur, the system will adjust its decision-making and control strategies to ensure vehicle safety. In some cases, because the decision-making ability of the autonomous driving system is not mature enough, the system may need to return control to the driver or request the driver's intervention.

[0091] See also Figure 2 , Figure 2 is a flow chart of another vehicle communication method according to an exemplary embodiment. Figure 2 As shown, the vehicle communication method can be applied to a second vehicle, including the following steps.

[0092] In step S201, the driving information and / or the driver information of the second vehicle is obtained; In step S202, a light signal corresponding to the driving information and / or driver information of the second vehicle is determined; In step S203, an optical signal is sent to a first vehicle around a second vehicle through an optical signal sending module, so that the first vehicle receives the optical signal sent by the second vehicle through an optical signal receiving module and analyzes the optical signal to obtain driving information and / or driver information.

[0093] For example, the second vehicle can obtain the driving information and / or driver information of the second vehicle through the intelligent driving system of the second vehicle, wherein the intelligent driving system interacts with sensors on the vehicle to obtain the driving information and / or driver information of the first vehicle.

[0094] For example, the second vehicle can obtain driving information and / or driver information, and then determine the optical signal corresponding to the driving information and / or driver information of the second vehicle through optical signal modulation. The optical signal sending module sends an optical signal to the first vehicle around the second vehicle, so that the first vehicle receives the optical signal sent by the second vehicle through the optical signal receiving module, and analyzes the optical signal to obtain the driving information and / or driver information.

[0108] Regarding the vehicle communication device applied to the first vehicle in the above embodiment, the specific manner in which each module performs operations has been described in detail in the embodiment of the vehicle communication method applied to the first vehicle, and will not be elaborated here.

[0109] Reference Figure 4 , Figure 4 FIG. 1 is a block diagram of a vehicle communication device according to an exemplary embodiment. Figure 4 As shown, the vehicle communication device can be applied to a second vehicle, and includes an optical signal modulation module 401 and an optical signal sending module 402 .

[0110] The optical signal modulation module 401 is configured to obtain the driving information and / or the driver information of the second vehicle and determine the optical signal corresponding to the driving information and / or the driver information of the second vehicle; The optical signal sending module 402 is configured to send an optical signal to a first vehicle around a second vehicle, so that the first vehicle receives the optical signal sent by the second vehicle through the optical signal receiving module and analyzes the optical signal to obtain driving information and / or driver information.

[0111] Regarding the vehicle communication device applied to the second vehicle in the above embodiment, the specific manner in which each module performs operations has been described in detail in the embodiments of the vehicle communication method applied to the first vehicle and the second vehicle, and will not be elaborated here.

[0112] Based on the same inventive concept, the present disclosure also provides a vehicle communication system, see Figure 5 and 6 , including a first vehicle and a second vehicle, the first vehicle and the second vehicle each including an optical signal modulation module, an optical signal sending module, an optical signal receiving module and an optical signal parsing module; The second vehicle is used to obtain the driving information and / or driver information of the second vehicle through the optical signal modulation module, determine the optical signal corresponding to the driving information and / or driver information of the second vehicle, and send the optical signal to the first vehicles around the second vehicle through the optical signal sending module; The first vehicle is used to receive the optical signal sent by the second vehicle around the first vehicle through the optical signal receiving module; and analyze the optical signal through the optical signal analyzing module to obtain the driving information and / or the driver information.

[0113] For example, the vehicle communication system includes a first vehicle and a second vehicle, wherein the first vehicle and the second vehicle each include an optical signal modulation module, an optical signal sending module, an optical signal receiving module, and an optical signal parsing module. The optical signal sending module for the second vehicle can be used to send an optical signal to the first vehicle around the second vehicle, so that the optical signal receiving module of the first vehicle around the second vehicle receives the optical signal. The optical signal receiving module for the first vehicle can be used to receive an optical signal sent by the optical signal sending module of the second vehicle around the first vehicle.

[0114] Understandably, Figure 5 In the above, car A, car B and car C can all be used as the first vehicle and / or the second vehicle. For example, when car B sends light signals to the surrounding cars A and C, car B is used as the second vehicle, and car A and car C are used as the first vehicle.

[0115] For example, when Figure 5 In the case where car B is the first vehicle, cars A and C can both be the second vehicles. However, the first vehicle and the second vehicle do not need to be adjacent. For example, when Figure 5 In the case where car A is the first vehicle, if car A can receive the light signal from car C or send the light signal to car C, then both car B and car C can be the second vehicle; on the contrary, when Figure 5 In the case where car A is the first vehicle, if car A cannot receive the optical signal from car C or send the optical signal to car C, only car B can be the second vehicle.
