Fig. 1 is a diagram of an application environment of a driving information transmission method provided in some embodiments, as shown in fig. 1, in the application environment, including an automobile 110, an intermediate server 120, and an information server 130. The car 110 may be installed with corresponding software, and the driving reference terminal may be used to perform early warning on driving risks and determine whether there is a risk, such as a vehicle collision risk. Of course, the driving reference terminal may also be disposed on other devices, for example, in the cloud. During the driving process of the automobile, it may be necessary to acquire information of other vehicles, such as the speed and distance of nearby vehicles, so as to make a decision based on the information. The information server can acquire vehicle running information and road information corresponding to each vehicle on the road. The driving reference in the car 110 may therefore send the geographical location, where the car is located, to the information server 130 via the intermediate server 120. The information server 130 determines driving reference information, such as information of other vehicles and road information, according to the geographical position. The driving reference information is sent to the intermediate server 120, and the intermediate server 120 sends the driving reference information to the driving reference terminal, so that the driving reference terminal can make driving operation decisions, such as slowing down the vehicle speed or changing lanes, according to the driving reference information. The driving reference information may also be drive test sensing information, which is environmental information sensed by one or more sensors of a camera, a night vision camera, a laser radar, or a millimeter wave radar. The traffic situation perception of the road section where the vehicle is located can be achieved through the road test perception information, the traffic situation can be transmitted to the automatic driving vehicle for decision making, the road test data support is provided for a perception system of the automatic decision making automatic driving vehicle, the automatic driving vehicle is protected, and the vehicle can be driven by people.

In some embodiments, the automobile may be other movable objects, such as an airplane or a drone.

The server may be an independent physical server, or a server cluster composed of a plurality of physical servers, or a cloud server providing basic cloud computing services such as a cloud server, a cloud database, a cloud storage, and a CDN. The vehicle 110, the intermediate server 120, and the information server 130 may be connected by a communication connection manner such as a network, which is not limited herein.

As shown in fig. 2, in some embodiments, a driving information transmission method is proposed, and this embodiment is mainly exemplified by applying the method to the intermediate server 120 in fig. 1, which supports communication with the information server and the driving reference terminal. The method specifically comprises the following steps:

step S202, target driving reference information sent by the information server is obtained according to the geographic position sent by the driving reference end.

Specifically, the driving reference information is information that needs to be referred to during driving, for example, a driving operation to be performed may be determined according to the driving reference information, the driving operation may be one or more of lane changing, acceleration, deceleration, or prompting of another vehicle, and the driving operation may be performed by a person or a machine, that is, automatic driving. The driving reference information may include one or more of driving object-related information and road-related information. The information related to the traveling object may include, for example, one or more of the number of vehicles, the type of vehicles, the speed of vehicles, the position of vehicles, the acceleration of vehicles, and the direction of vehicles. The road-related information may be information such as a road type, a safe distance and a road width corresponding to the road. The driving reference information may be transmitted to the information server by other vehicles or sensors.

The geographic position corresponding to the driving reference end may be a current position of the vehicle corresponding to the driving reference end, or may be another position. The driving reference terminal may be mounted on a vehicle, and the geographic position of the vehicle may be acquired by a GPS (Global Positioning System) device. The geographic location may be represented by longitude and latitude. Or the driver can input a designated geographic position at the driving reference end and send the geographic position to the information server through the intermediate server. The target driving reference information is obtained according to the geographic position, and is the driving reference information corresponding to the geographic position, the area where the vehicle is located can be determined according to the geographic position, and the driving reference information corresponding to the target area is obtained, wherein the target area can be an area with the geographic position as the center.

The fact that the intermediate server supports communication with the information server and the driving reference terminal means that the intermediate server can be compatible with the information server and the driving reference terminal at the same time. For example, the module in the intermediate server connected to the information server is written in a programming language supported by the information server. And a module connected with the driving reference end in the intermediate server is written by adopting a programming language supported by the driving reference end.

In some embodiments, the obtaining of the target driving reference information includes: acquiring a safe driving distance, and determining a target geographical area according to the safe driving distance by taking the geographical position as a center; and acquiring the driving related information corresponding to the driving object in the target geographic area as target driving reference information.

Specifically, the safe running distance is a necessary separation distance that the two vehicles keep during running in order to avoid an accidental collision of the preceding and following vehicles, and may be, for example, 100 meters. The safety driving distance can be preset, the safety driving distances corresponding to different reason types can be different, and the information server can determine the safety driving distance according to the type of the road. The target geographic area may include a safe driving area, which may be a square having a length of 2 times the safe driving distance centered on the geographic location of the driving reference end. The traveling object refers to an object that can move, such as a vehicle. The travel-related information may be information related to a travel behavior of the travel object, and may include at least one of a vehicle type, a vehicle speed, a vehicle position, a vehicle acceleration, or a vehicle direction, for example. The driving-related information of the driving object that is driven in the target geographical area may be acquired as the target driving reference information corresponding to the geographical location.

In some embodiments, the safe driving area may be a rectangle centered at the geographic location of the driving reference end, having a length of 2 times the safe driving distance and a width of 2 times the road width. The length of the side corresponding to the direction in which the vehicle travels is taken as the length. The corresponding formula may be expressed as formula (1), where safe distance represents a safe driving distance, roadwidth represents a width of a road, road represents a position corresponding to a safe driving area, | roadX | represents an absolute value of a difference from an X coordinate of a geographic position, | roadY | represents an absolute value of a difference from a Y coordinate of a geographic position, that is, a coordinate of a geographic position corresponding to a safe driving area and a coordinate of a geographic position of a vehicle, an absolute value of a difference on an X axis is equal to or less than the safe driving distance, and an absolute value of a difference on a Y axis is equal to or less than the road width. For example, as shown in fig. 3, assuming that a circle at the center indicates the position of the vehicle from which the driving reference information is to be acquired and an arrow indicates the traveling direction of the vehicle, the target geographical area may be a rectangle in fig. 3, a being the length of the target geographical area and being equal to 2 times the safe traveling distance, and b being the width of the target geographical area and being equal to 2 times the road width. In the vehicle, attention needs to be paid to whether or not a region within a safe distance between the front and rear sides of the vehicle is dangerous, and also to whether or not a region within a distance between the right and left road widths of the vehicle is dangerous. For example, when the vehicle is at the rightmost end of the road, whether the area on the left side of the vehicle is dangerous or not needs to be concerned, when the vehicle is at the leftmost end of the road, whether the area on the right side of the vehicle is dangerous or not needs to be concerned, and when the vehicle is in the middle of the road, whether the area on the left side and the area on the right side are dangerous or not needs to be concerned, so that 2 times of road width is selected as the width of a safe driving area, the obtained driving reference information can be ensured to be complete, and.

In some embodiments, the target geographic area may also include a message broadcast area, which refers to an area where a vehicle is to broadcast a message. For example, when the vehicle determines that there is a risk of collision with the preceding vehicle based on the target driving reference information, the prompt information may be transmitted to the preceding vehicle. The size of the message broadcast area may be predetermined. For example, the message broadcast area may be an ellipse whose center point is the position of the vehicle for which the driving reference information is to be acquired. The size of the major and minor half shafts may be set. The corresponding formula can be expressed as formula (2), wherein the llipse indicates the position corresponding to the ellipse, i.e., the message broadcasting area, (llipsex, llipsey) is an element in the llipse, and characterizes the position within the llipse area, (requestX, requestY) is the requested position, i.e., the geographical position of the vehicle that needs to drive the reference information, and semimajor and semiminor are the major and minor semi-axes of the llipse area, respectively. The coordinates of the geographic location corresponding to the message area are within the ellipse. The major axis is the effective distance that a frame of V2X (vehicle to outside information exchange) messages can be transmitted along the direction of travel of the road, and the minor axis is the effective distance that a V2X message can be transmitted along the direction perpendicular to the road.

In some embodiments, the target geographic area may be the union of the safe driving area and the message broadcast area. Thus, the vehicle-related information corresponding to the vehicle in the safe driving area can be acquired, and the vehicle-related information corresponding to the vehicle in the message broadcasting area can also be acquired. The target geographic area can be represented by formula (3), and the position represents a position corresponding to the target geographic area.

road＝{(roadX,roadY)||roadX|≤safedistance,|roadY|≤roadwidth} (1)

position＝road∪ellipse (3)

In some embodiments, the driving reference information may also include vehicle collision risk information, such as a collision probability of the vehicle. For example, the collision probability can be calculated according to vehicle-related information and theory-related information, and the collision strength between vehicles can be calculated according to vehicle information (such as the relative speed of the vehicles, the included angle of the traveling wind directions between the vehicles, the mass of the vehicles) and other information such as surface viscosity and curvature, as well as a gravitational field theory model, a spring potential energy model and a doppler effect model in the field of physics, and then divided by the standard collision strength to obtain the collision probability.

And step S204, determining a driving information subscription end corresponding to the target driving reference information.

Specifically, the subscription terminal is used for subscribing to the message, and the driving information subscription terminal corresponding to the target driving reference information is a subscription terminal that subscribes to the driving reference information. For example, the driving information subscriber is a subscriber who subscribes to a topic corresponding to the driving reference information. The topic (topic) may also refer to the type of information, and a topic corresponding to each piece of information may be set as needed, for example, the topic may include a topic corresponding to a geographic location and a topic corresponding to driving reference information. Therefore, after the target driving reference information is obtained, the topic corresponding to the target driving reference information can be determined, and the subscription terminal subscribed with the topic is searched to serve as the driving information subscription terminal.

And step S206, sending the target driving reference information to a driving information subscription terminal, and sending the target driving reference information to a corresponding driving reference terminal through the driving information subscription terminal.

Specifically, the target driving reference information may be added to a message queue corresponding to a theme corresponding to the driving reference information, and the driving information subscriber acquires the target driving reference information from the corresponding message queue. The target driving reference information can also be sent together with the driving reference end identifier corresponding to the driving reference end, so that the driving information subscriber can send the target driving reference information to the corresponding driving reference end according to the driving reference end identifier.

In some embodiments, after the driving reference end obtains the driving reference information, the driving risk, such as the collision probability, may be determined according to the driving reference information. For example, the collision probability can be obtained by calculating the collision strength between vehicles according to vehicle information (such as the relative speed of the vehicles, the included angle of the traveling wind directions between the vehicles, the vehicle mass) and other information such as the surface viscosity, the bending degree, and a gravity field theory model, a spring potential energy model and a Doppler effect model in the field of physics, and then dividing the collision strength by the standard collision strength. After the collision probability is obtained, if the collision probability is greater than a preset probability, for example, 0.5, a prompt message may be sent.

According to the driving information transmission method, the intermediate server supports communication with the information server and the driving reference terminal, the target driving reference information sent by the information server can be obtained according to the geographical position sent by the driving reference terminal by obtaining the target driving reference information, the driving information subscription terminal corresponding to the target driving reference information is determined, the target driving reference information is sent to the driving information subscription terminal, and the target driving reference information is sent to the corresponding driving reference terminal through the driving information subscription terminal. Therefore, the information server and the driving reference end can be connected, the driving reference information which is sent by the information server and obtained according to the geographical position is sent to the driving reference end, and the information transmission efficiency is improved.

In some embodiments, the intermediate server may have a driving information publishing terminal, an agent terminal, and a driving information subscribing terminal installed therein. Step S202, acquiring the target driving reference information sent by the information server includes: acquiring target driving reference information sent by an information server through a driving information issuing end; step S204, determining the driving information subscription end corresponding to the target driving reference information includes: the target driving reference information published by the driving information publishing terminal is obtained through the agent terminal, and the driving information subscribing terminal corresponding to the target driving reference information is determined according to the theme corresponding to the target driving reference information.

Specifically, a driving information issuing terminal (publisher) is used to issue driving reference information. The driving information publishing end publishes information to the agent end, the agent end (browse) adds the information to a message queue corresponding to a topic according to the topic of the information, and the Subscriber end (Subscriber) acquires the information from the message queue, wherein the driving information publishing end, the agent end and the Subscriber end can be integrated in the same device, for example, corresponding publishing modules, agent modules and subscription modules are installed in the same device. But may of course also be located in a different device. Through the publish-broker-subscribe model, a publisher does not send messages directly to a particular subscriber. But the agent end determines the corresponding subject of the message and then sends the subject to the corresponding subscriber. Therefore, the response capability of the publisher is improved, the information transmission efficiency is further improved, and the driving reference information can be sent to the corresponding driving reference end in time. Because the Publisher (Publisher) does not need to determine the subscribers to the information, it can efficiently send information to the input channel and then proceed with other publication tasks without waiting for the subscriber to receive the message. Before publishing the driving information, the driving information subscription terminal may request the broker terminal to subscribe to a topic corresponding to the driving information.

In some embodiments, the obtaining, by the driving information issuing terminal, the target driving reference information sent by the information server includes: receiving target driving reference information sent by an information server through a client corresponding to the information server; and acquiring target driving reference information from a client corresponding to the information server through a driving information issuing end.

Specifically, the client corresponding to the information server is used for communicating with the information server, and the client corresponding to the information server and the driving information publishing terminal can be located on the same device, so that the target driving reference information is obtained by communicating with the information server through the client corresponding to the information server, and then the target driving reference information is sent to the driving information publishing terminal through the client corresponding to the information server, so that convenience and convenience are achieved.

In some embodiments, the driving information publishing terminal in the intermediate server is written in a programming language supported by the information server, so that the intermediate server supports communication with the information server and the driving reference terminal.

Specifically, The Programming Language is a formal Language used to define a computer program, and may be, for example, C + + (The C + + Programming Language), JAVA, PHP, and nodjs. Because the information server is generally a platform provided by a third party, the structure is complex, the requirement on the other end for communication with the information server is high, for example, the information server needs to be written by a programming language supported by the information server to be accessed, so that the driving information issuing end can be written by the programming language supported by the information server to ensure that the information server can be accessed, namely, the information server is communicated.

In some embodiments, the step S206 of sending the target driving reference information to the corresponding driving reference terminal through the driving information subscriber terminal includes: the target driving reference information is sent to a client corresponding to the driving reference end through a driving information subscription end; and sending the target driving reference information to the driving reference end through the client corresponding to the driving reference end.

Specifically, the driving reference terminal may be used as a server, for example, a code for executing a task of the server is embedded in the driving reference terminal, or a separate server is configured on the vehicle, and a client corresponding to the server is configured on another device to communicate with the server, where the server may be a HTTP (HyperText Transfer Protocol) based server, and may receive HTTP information and send HTTP information. The client corresponding to the driving reference end and the driving information subscription end can be arranged on the same device, so that the target driving reference information is sent through the communication between the driving information subscription end and the client corresponding to the driving reference end, and then the target driving reference information is sent to the driving reference end by the client corresponding to the driving reference end, so that the device is convenient and fast.

In some examples, sending the target driving reference information to the driving reference end through a client corresponding to the driving reference end includes: the client corresponding to the driving reference end sends the target driving reference information to the corresponding server, so that the server writes the target driving reference information into the shared storage area, and the driving reference end acquires the target driving reference information from the shared storage area.

Specifically, the shared storage area refers to a shared storage space, and may be a shared file or a shared cache. The shared storage area may be located on the same device as the driving reference end, for example, on a storage device of the vehicle, or on another device. For example, the driving reference terminal and the service terminal may share one or more local files therein, and the local files are used for storing driving reference information so as to realize information transmission between the driving reference terminal and the service terminal.

In some embodiments, as shown in fig. 4, the driving information transmission method may further include the steps of:

and step S402, acquiring the geographical position sent by the driving reference end.

Specifically, the geographic position sent by the driving reference end can be acquired through the geographic position publishing end.

Step S404, determining a geographic position subscriber corresponding to the geographic position.

Specifically, the geographic location subscriber corresponding to the geographic location is a subscriber that subscribes to the geographic location. For example, the geographic location subscriber may be a subscriber that subscribes to a topic corresponding to the geographic location. The theme corresponding to each piece of information can be set as required, and for example, the theme corresponding to the geographic location and the theme corresponding to the driving reference information can be included. Therefore, after the geographic position is obtained, the topic corresponding to the geographic position can be determined, and the subscription end subscribed with the topic is searched to serve as the geographic position subscription end.

Step S406, the geographic position is sent to a geographic position subscriber, and the geographic position is sent to an information server through the geographic position subscriber.

Specifically, the geographic position may be added to a message queue corresponding to a theme corresponding to the geographic position, and the geographic position subscriber acquires the geographic position from the corresponding message queue, where the target driving reference information may also be sent together with a driving reference end identifier corresponding to the driving reference end, and therefore, after the corresponding target driving reference information is obtained, the target driving reference information may be sent to the corresponding driving reference end according to the driving reference end identifier. According to the embodiment of the application, the intermediate server can be connected with the information server and the driving reference end, and the information sent by the driving reference end is sent to the information server, so that the information transmission efficiency is improved.

In some embodiments, the intermediate server may have installed therein a geographic location publisher and a geographic location subscriber. Step S402, acquiring the geographic position sent by the driving reference terminal includes: acquiring a geographical position sent by a driving reference end through a geographical position issuing end; step S404, determining the geographic location subscriber corresponding to the geographic location includes: and acquiring the geographic position published by the geographic position publishing terminal through the agent terminal, and determining a geographic position subscribing terminal corresponding to the geographic position according to the theme corresponding to the geographic position.

Specifically, a geographic location publisher (publisher) is used to publish the geographic location. The method includes the steps that a geographic position publishing terminal publishes information to a proxy terminal, the proxy terminal (spoke) adds the information into a message queue corresponding to a topic according to the topic of the information, and a Subscriber terminal (Subscriber) acquires the information from the message queue, wherein the geographic position publishing terminal, the proxy terminal and the geographic position Subscriber terminal can be integrated in the same server, for example, corresponding publishing modules, proxy modules and subscription modules are installed in the same server. But may of course also be located in a different device. Through the publish-broker-subscribe model, a publisher does not send messages directly to a particular subscriber. The proxy end determines the topic corresponding to the published message and then sends the topic to the corresponding subscriber. Therefore, the response capability of the publisher is improved, and the information transmission efficiency is further improved. Before sending the geographic location, the geographic location subscriber may request the broker to subscribe to a topic corresponding to the geographic location.

In some embodiments, the obtaining, by the geographic position issuing terminal, the geographic position sent by the driving reference terminal includes: receiving the geographical position sent by the driving reference end through a client corresponding to the driving reference end; and acquiring the geographic position from the client corresponding to the driving reference end through the geographic position issuing end.

Specifically, the client corresponding to the driving reference end is used for communicating with the server in the driving reference end, and the geographic position issuing end and the client corresponding to the driving reference end can be located on the same device.

In some embodiments, the driving information transmission method further includes: and acquiring candidate driving reference information from a third-party application through a geographic position issuing end, and sending the candidate driving reference information to an information server so that the information server screens the candidate driving reference information according to the geographic position to obtain target driving reference information.

Specifically, the third-party system may be a system that stores driving reference information, for example, a system that stores information obtained by radar detection, a system that stores information obtained by satellite, and a system that stores information captured by a camera. The information detected by the radar may be, for example, a vehicle speed and a vehicle distance. The information obtained by the satellite may be a position and the information captured by the camera may be a picture of a traffic sign. Different types of driving reference information may be acquired by different sensors, and thus various types of information may be acquired from a third-party system. The geographic position release terminal can be provided with an application program interface for acquiring the driving reference information of each geographic area from a third-party application. And then the information server determines a corresponding target geographic area according to the position of the vehicle, and acquires driving reference information corresponding to the target geographic area as target reference information. The Application Programming Interface may be a RESTful API (Representational State Transfer Application Programming Interface). By arranging the application program interface at the release end, the method can be adapted to different third-party applications, information provided by the third-party applications can be obtained, and the obtained driving reference information can be richer.

Specifically, the driving reference end acquires drive test perception information by accessing the local file, performs driving risk calculation based on the information, and then outputs the collision probability of the collision between the vehicle and other vehicles.

In some embodiments, the vehicle may also output a collision probability of a collision between other vehicles. For example, the collision probability between the vehicles may be output in the form of a matrix. Wherein the ith row and jth column elements of the matrix represent the probability that vehicle j will collide with vehicle i. For example, 0.11 in row 3, column 4 identifies the probability that vehicle 4 will collide with vehicle 3.
