[0052] See also Figure 1 , Figure 1 A schematic diagram of the road surface information transmission system architecture provided in an embodiment of the present application, wherein the road surface information transmission system shown includes a highway subsystem 101 and a vehicle subsystem 102, wherein the highway subsystem 101 includes a road sensor, at least one road surface NFC reader / writer, and a road surface central control unit, and the vehicle subsystem 102 includes an on-board NFC reader / writer and a vehicle central control unit.

The road NFC reader / writer reads the vehicle information through the vehicle-mounted NFC reader / writer, and transmits the vehicle information to the road central control unit. The road central control unit determines the road surface information based on the vehicle information read by each road NFC reader / writer and the road data collected by the road sensor, and writes the road surface information into each road NFC reader / writer. Each road NFC reader / writer transmits the road surface information to the vehicle-mounted NFC reader / writer.

[0055] In some embodiments, the highway subsystem 101 also includes a road surface display screen and a traffic management unit, which are respectively interconnected with the road surface central control unit, wherein the road surface display screen is used to display road surface information, and the traffic management unit is used to send traffic information to the road surface central control unit, and receive road surface information sent by the road surface central control unit, and adjust the traffic control signal of the driving road surface based on the road surface information.

[0056] Among them, traffic information includes but is not limited to road maintenance information, lane direction change information, road traffic light signals, road control information, etc.; traffic control signals include but are not limited to traffic light control signals, etc.

[0057] Specifically, Figure 2 As shown, Figure 2 This is a road surface information transmission timing diagram based on a road surface information transmission system provided in an embodiment of the present application. The road surface NFC reader / writer reads vehicle information through an on-board NFC reader / writer, and transmits the vehicle information and the reading time of the vehicle information to a road surface central control unit; the road surface central control unit determines the road surface information of the driving road surface based on the vehicle information read by each road surface NFC reader / writer in the past period of time and the reading time of each vehicle information, and transmits the road surface information to each road surface NFC reader / writer; the road surface NFC reader / writer responds to the scanning operation of the current road surface NFC reader / writer by the on-board NFC reader / writer deployed in the target vehicle, and transmits the road surface information and the lane information of the lane where the current road surface NFC reader / writer is located and the lane information of the lane where the road surface NFC reader / writer is located to the target vehicle; the vehicle central control unit in the target vehicle performs assisted driving based on the road surface information and the lane information of the lane where the road surface NFC reader / writer is located obtained by the on-board NFC reader / writer.

[0058] Optionally, the past period of time may be the past hour, the past minute, the past ten minutes, etc., and this embodiment of the present application does not specifically limit this.

[0059] Optionally, assisted driving can be to obtain the current driving speed of the target vehicle, obtain the road surface information by the on-board NFC reader and the lane information of the lane where the road NFC reader is located, determine the target driving speed of the target vehicle, and output a prompt message when the current driving speed does not match the target driving speed, thereby ensuring safe driving of the target vehicle.

[0060] The road surface information transmission system provided in the embodiment of the present application writes the determined road surface information into the road surface NFC reader / writer, and transmits the road surface information to the target vehicle deployed with the on-board NFC reader / writer through the road surface NFC reader / writer. In this way, it does not rely on GPS / GPRS signals and can still work normally in areas with no signals, thereby achieving timely acquisition of road surface information. At the same time, the road surface information is determined through the vehicle information read by the road surface NFC reader / writer, and sudden situations on the driving road surface can be identified in time, thereby reducing the driving safety risks caused by untimely acquisition of road surface information and improving driving safety.

[0061] based on Figure 1 The road surface information transmission system provided in this application embodiment provides a road surface information transmission method suitable for Figure 1 The highway subsystem 101 in Figure 3 As shown, Figure 3 2 is a flow chart of a road surface information transmission method provided in an embodiment of the present application. The road surface information transmission method shown includes at least steps 210 to 240, which are described in detail as follows:

[0062] Step 210, obtaining the vehicle information read by each NFC reader on the road surface and the reading time of each vehicle information.

[0063] Among them, vehicle information includes but is not limited to vehicle type, license plate information, vehicle model, etc.

[0064] In some implementations, the vehicle information read by each NFC reader on the road surface within a preset time period and the reading time of each vehicle information can be obtained.

[0065] Optionally, after reading the vehicle information, the road NFC reader can transmit the vehicle information and the reading time of the vehicle information to the road central control system. The road central control system stores the vehicle information read by each road NFC reader and the reading time of each vehicle information, and obtains the stored vehicle information read by each road NFC reader and the reading time of each vehicle information within the preset time period at every preset time interval.

[0066] When a vehicle in a lane passes through a road NFC reader / writer deployed in the lane, for a vehicle with an onboard NFC reader / writer deployed, a connection is established between the road NFC reader / writer and the onboard NFC reader / writer of the vehicle, and the onboard NFC reader / writer transmits the identification information of the onboard NFC reader / writer to the road NFC reader / writer, and the road NFC reader / writer obtains the vehicle information of the vehicle based on the identification information of the onboard NFC reader / writer, and uploads the vehicle information of the vehicle and the reading time of the vehicle information to the road central control system. Specifically, Figure 4 As shown, Figure 4 2 is a flow chart of a vehicle information acquisition method provided in an embodiment of the present application. The vehicle information acquisition method shown includes steps 211 to 213:

[0067] Step 211, for each road NFC reader / writer, the road NFC reader / writer responds to a scanning event of an on-board NFC reader / writer deployed in a vehicle on the driving road, and obtains identification information of the on-board NFC reader / writer deployed in the vehicle.

[0068] Step 212, based on the identification information of the vehicle-mounted NFC reader / writer deployed in the vehicle and the preset vehicle database, the vehicle information of the vehicle is obtained, and the current time is determined as the reading time of the vehicle information of the target vehicle.

[0069] The vehicle database includes identification information of multiple vehicle-mounted NFC readers and writers and vehicle information corresponding to the identification information of each vehicle-mounted NFC reader and writer;

[0070] Step 213, the vehicle information of the vehicle and the reading time of the vehicle information are transmitted to the road central control unit.

[0071] Optionally, the road NFC reader can store the vehicle information and the reading time of the vehicle information after reading it, and transmit the vehicle information read within the preset time and the reading time of each vehicle information to the road central control system at every preset time interval.

[0072] Step 220, determining the road surface information of the driving road surface according to the vehicle information read by the NFC reader / writer on each road surface and the reading time of each vehicle information.

[0073] The road surface information includes, but is not limited to, whether the driving road surface is congested, and the degree of congestion of the driving road surface when congestion exists.

[0074] In some embodiments, the number of vehicles on the road surface and the driving speed of the road surface can be determined based on the vehicle information read by the NFC reader on each road surface and the reading time of each vehicle information, and the road surface information of the road surface can be determined based on the number of vehicles and the driving speed of the road surface.

[0075] Optionally, the type of vehicle information can be determined based on the vehicle information read by the NFC reader on each road surface, and the number of types of vehicle information can be determined as the number of vehicles on the driving road surface. It is understandable that the same vehicle information is determined as one type.

[0076] Optionally, the vehicle information read by each road NFC reader can be compared, and the same vehicle information can be divided into a set to obtain at least one vehicle information set. For each vehicle information set, the earliest reading time and the latest reading time in the vehicle information set are determined according to each reading time in the vehicle information set. The distance between the road NFC reader corresponding to the earliest reading time in the vehicle information set and the road NFC reader corresponding to the latest reading time are determined according to the distance between each road NFC reader. The driving speed of the vehicle corresponding to the vehicle information set is obtained according to the distance between the road NFC reader corresponding to the earliest reading time in the vehicle information set and the road NFC reader corresponding to the latest reading time, and the time interval between the earliest reading time and the latest reading time in the vehicle information set. Based on the driving speed of the vehicle corresponding to each vehicle information set, the driving speed of the vehicle on the driving road is obtained. Exemplarily, the average driving speed of the vehicles corresponding to each vehicle information set can be determined as the driving speed of the vehicle on the driving road.

[0077] It can be understood that the vehicle information set includes the time when the same vehicle information is read by different road NFC readers and writers and the identification information of the different road NFC readers and writers.

[0078] For example, take two road NFC readers deployed on a driving road as an example, the distance between road NFC reader A and road NFC reader B is 1 km, if the vehicle information read by road NFC reader A is che1, che2 and che3 respectively, the vehicle information read by road NFC reader B is che1 and che2 respectively, the reading time corresponding to the vehicle information che1, che2 and che3 read by road NFC reader A is 12:00, 12:10 and 12:20 respectively, and the reading time corresponding to the vehicle information che1 and che2 read by road NFC reader B is 12:10 and 12:30 respectively, then the vehicle information che1, che2 and che3 are determined. The vehicles corresponding to he2 have passed through the road NFC reader A and the road NFC reader B. For the vehicle information che1, according to the reading time when the road NFC reader A and the road NFC reader B read the vehicle information che1 and the distance between the road NFC reader A and the road NFC reader B, the driving speed of the vehicle corresponding to the vehicle information che1 is 100m / min. For the vehicle information che2, according to the reading time when the road NFC reader A and the road NFC reader B read the vehicle information che1 and the distance between the road NFC reader A and the road NFC reader B, the driving speed of the vehicle corresponding to the vehicle information che2 is 50m / min.

[0079] Optionally, the driving speed of vehicles on the driving road can be compared with a preset speed threshold, and the number of vehicles can be compared with a preset vehicle number threshold. When the driving speed of vehicles on the driving road is less than the preset speed threshold and the number of vehicles is greater than the preset vehicle number threshold, it is determined that there is congestion on the driving road, and a congestion coefficient is obtained based on the number of vehicles and the driving speed of the driving road. Based on the mapping relationship between the preset coefficient and the congestion degree, the congestion degree of the driving road is obtained.

[0080] Among them, the mapping relationship between the preset coefficient and the congestion degree is used for the mapping relationship between the congestion coefficient and the congestion degree of teammates. In some implementations, the congestion degree includes mild congestion, moderate congestion and severe congestion.

[0081] Optionally, the congestion coefficient can be determined by calculating the coefficient according to the number of vehicles and the speed of the road surface and a preset coefficient estimation model, wherein the preset coefficient estimation model can be a mathematical model, a machine learning model, or an estimation model based on a neural network.

[0082] Step 230 , transmit the road surface information of the driving road surface to each road surface NFC reader / writer, so as to transmit the road surface information to the target vehicle through each road surface NFC reader / writer.

[0083] The target vehicle is a vehicle that is currently parked on any NFC reader / writer on the road and is equipped with an on-board NFC reader / writer.

[0084] In some embodiments, each road NFC reader / writer stores lane information of the lane where the road NFC reader / writer is located and road surface information of the driving road surface, wherein the lane information includes but is not limited to lane direction, lane speed limit, lane front dashed and solid line information, etc.

[0085] In some embodiments, for each road surface NFC reader / writer, when a target vehicle equipped with an on-board NFC reader / writer passes by the road surface NFC reader / writer, the on-board NFC reader / writer scans the road surface NFC reader / writer, and the road surface NFC reader / writer responds to the scanning operation of the on-board NFC reader / writer deployed in the target vehicle on the driving road surface on the road surface NFC reader / writer, and transmits the road surface information and the lane information of the lane where the road surface NFC reader / writer is located to the target vehicle.

[0086] The road surface information transmission method provided in the embodiment of the present application writes the determined road surface information into the road surface NFC reader / writer, and transmits the road surface information to the target vehicle deployed with the on-board NFC reader / writer through the road surface NFC reader / writer. In this way, it does not rely on GPS / GPRS signals and can still work normally in areas with no signals, thereby achieving timely acquisition of road surface information. At the same time, the road surface information is determined through the vehicle information read by the road surface NFC reader / writer, and sudden situations on the driving road surface can be identified in time, thereby reducing the driving safety risks caused by untimely acquisition of road surface information and improving driving safety.

[0087] Considering the existing road congestion prediction methods, the navigation system mainly determines whether there is congestion on the road by obtaining the number of vehicles using the navigation system on the driving road. Since the navigation system needs to exchange data with the background server, when the network environment of the driving road is not good or the number of terminals accessing the background server is large, the data update of the navigation system is delayed, and it is impossible to predict the emergency situation ahead, thereby increasing the driving safety risk. Based on this, in order to obtain the road surface information of the driving road in time and reduce the driving safety risk, in some embodiments, by deploying a road NFC reader on the driving road, deploying a NFC reader on the bottom of the vehicle The on-board NFC reader / writer and the road NFC reader / writer will read the vehicle information of the vehicles passing by the road NFC reader / writer, and upload the vehicle information to the road central control unit. The road central control unit determines the driving status of the road based on the vehicle information read by different road NFC readers / writers, determines the road information based on the driving status, and writes the road information into the road NFC reader / writer in real time. When the vehicle passes the road NFC reader / writer, the road NFC reader / writer transmits the road information to the on-board NFC reader / writer. In this way, when the network environment of the driving road is not good, the vehicle can still obtain the road information ahead, thereby reducing the driving safety risk.

[0088] The driving state is used to characterize whether there is congestion on the driving road, which includes congestion and smoothness.

[0089] Specifically, Figure 5 As shown, Figure 5 2 is a flow chart of a road surface information determination method provided in an embodiment of the present application. The road surface information determination method shown includes steps 221 to 222:

[0090] Step 221, determining the driving state of the driving road surface according to the vehicle information read by the NFC reader / writer on each road surface and the reading time of the NFC reader / writer on each road surface.

[0091] In some embodiments, the driving speed of the vehicle on the driving road is obtained based on the vehicle information read by the NFC reader / writer on each road surface and the reading time of the NFC reader / writer on each road surface, and the driving speed is compared with a preset speed threshold. If the driving speed of the vehicle on the driving road is less than the preset speed threshold, the driving state of the driving road is determined to be congested; if the driving speed of the vehicle on the driving road is greater than or equal to the preset speed threshold, the driving state of the driving road is determined to be unobstructed.

[0092] Optionally, the time when the same vehicle information is read by the NFC readers on each road surface can be determined based on the vehicle information read by the NFC readers on each road surface and the reading time of the NFC readers on each road surface. Based on the time when the same vehicle information is read by the NFC readers on each road surface and the distance between the NFC readers on each road surface, the driving speed of the vehicle on the driving road surface can be obtained, and the driving state can be determined based on the driving speed. Specifically, Figure 6 As shown, Figure 6 22 is a flow chart of a method for determining a driving state provided in an embodiment of the present application. The method for determining a driving state shown includes steps 2211 to 2214:

[0093] Step 2211, based on the vehicle information read by each NFC reader on the road surface and the reading time of each NFC reader on the road surface, determine the reading time of the same vehicle information by each NFC reader on the road surface.

[0094] Step 2212, obtaining the driving speed of the vehicle on the driving road according to the time difference between the times when the same vehicle information is read by the NFC readers on the road surface and the distance between the NFC readers on the road surface.

[0095] In some embodiments, the maximum time difference and the first road NFC reader and the second road NFC reader corresponding to the maximum time difference can be determined based on the time difference between the times when the same vehicle information is read by each road NFC reader; the distance between the first road NFC reader and the second road NFC reader corresponding to the maximum time difference can be determined based on the distance between each road NFC reader; the driving speed of the vehicle corresponding to the vehicle information is obtained based on the distance between the first road NFC reader and the second road NFC reader corresponding to the maximum time difference and the maximum time difference, and the average of the driving speeds of the vehicles is determined as the driving speed of the vehicle on the driving road.

[0096] Step 2213: If the driving speed is less than a preset speed threshold, it is determined that the driving state of the driving road is congested.

[0097] Step 2214: If the driving speed is greater than or equal to the preset speed threshold, it is determined that the driving state of the driving road is unobstructed.

[0098] Step 222, determining the road surface information of the driving road surface based on the driving state of the driving road surface.

[0099] In some implementations, if the driving state of the driving road is congested, the congestion degree is determined and the congestion degree is used as the road information.

[0100] In some implementations, if the driving state of the driving road is smooth, the smooth road state is determined as the road surface information.

[0101] In some embodiments, in order to improve the accuracy of road surface information and further reduce driving safety risks, when the driving state of the driving road surface is congested, the congestion degree of the driving road surface can be determined according to the road data and driving speed of the driving road surface, and the road surface information is generated based on the congestion degree, wherein the road data includes a road image of the driving road surface and traffic data, wherein the road image can be collected by a road sensor set on the driving road surface, and the traffic data can be sent by a traffic management unit.

[0102] Specifically, Figure 7 As shown, Figure 7 22 is a flow chart of a method for determining road surface information based on road data and driving status provided in an embodiment of the present application. The method for determining road surface information based on road data and driving status shown includes steps 2221 to 2224:

[0110] In some implementations, the road surface information of the driving road may be generated according to the congestion level and traffic data of the driving road in a preset data format.

[0111] Step 2224: If the driving state of the driving road is unobstructed, the road surface information of the driving road is generated according to the traffic data.

[0133] Performing object detection on the road image of the driving road to determine the number of vehicles in the road image;

[0134] The congestion level of the driving road is determined based on the number of vehicles and the driving speed of the vehicles on the driving road.

[0135] In some embodiments, the road surface information transmission device further includes:

[0136] The vehicle information reading module is used for obtaining identification information of the on-board NFC reader / writer deployed in the vehicle in response to a scanning event of the on-board NFC reader / writer deployed in the vehicle on the driving road for each road NFC reader / writer; obtaining vehicle information of the vehicle based on the identification information of the on-board NFC reader / writer deployed in the vehicle and a preset vehicle database, and determining the current time as the reading time of the vehicle information of the target vehicle; the vehicle database includes identification information of multiple on-board NFC readers / writers and vehicle information corresponding to the identification information of each on-board NFC reader / writer.

[0137] The road surface information transmission device provided in the embodiment of the present application writes the determined road surface information into the road surface NFC reader / writer, and transmits the road surface information to the target vehicle deployed with the on-board NFC reader / writer through the road surface NFC reader / writer. In this way, it does not rely on GPS / GPRS signals and can still work normally in areas with no signals, thereby achieving timely acquisition of road surface information. At the same time, the road surface information is determined through the vehicle information read by the road surface NFC reader / writer, and sudden situations on the driving road surface can be identified in time, thereby reducing the driving safety risks caused by untimely acquisition of road surface information and improving driving safety.

[0138] In order to better illustrate the road surface information transmission method provided in the embodiment of the present application, on the basis of the road surface information transmission method, the road surface information transmission method is applied to assisted driving, and an assisted driving implementation method is provided. After the road surface information is generated, the road surface central control unit writes the road surface information into each road surface NFC reader / writer. When a vehicle equipped with an on-board NFC reader / writer passes by the road surface NFC reader / writer, the road surface information in the road surface NFC reader / writer is read, and the on-board central control unit deployed in the vehicle implements assisted driving based on the road surface information.

[0139] Specifically, Fig. 9 As shown, Fig. 9 is a flow chart of the assisted driving implementation method provided by the embodiment of the present application. The assisted driving implementation method shown can be Figure 1 The vehicle subsystem 102 in the embodiment is executed. Specifically, the assisted driving implementation method includes at least steps 910 to 920:

[0140] Step 910: Scan the road NFC reader / writer with the vehicle-mounted NFC reader / writer to obtain the road surface information in the road surface NFC reader / writer and the lane information of the lane where the road surface NFC reader / writer is located.

[0141] Step 920: Generate auxiliary driving information based on road surface information and lane information.

[0142] Among them, the auxiliary driving information includes but is not limited to congestion level, road condition information, target driving speed, driving direction, etc.

[0143] In some implementations, the congestion level and target driving speed can be determined based on the road information, the driving direction can be determined based on the lane information, and the auxiliary driving information can be generated based on the congestion level, target driving speed, and driving direction. Fig.10 As shown, Fig.10 9 is a flow chart of a method for generating assisted driving information provided in an embodiment of the present application. The method for generating assisted driving information shown includes steps 921 to 924:

[0144] Step 921, determining the congestion level of the driving road according to the road surface information.

[0145] Step 922, obtaining the vehicle's driving environment information.

[0146] Driving environment information includes but is not limited to road humidity, distance to the vehicle ahead, ambient temperature, road friction, etc.

[0147] In some implementations, the vehicle's driving environment information may be acquired through sensors deployed in the vehicle.

[0148] Step 923, determining the target driving speed of the vehicle according to the congestion level and driving environment information.

[0149] In some embodiments, speed prediction can be performed based on the congestion level and driving environment information to obtain the target driving speed of the vehicle. Alternatively, the congestion level and driving environment information can be input into a preset speed prediction model to perform speed prediction to obtain the target driving speed of the vehicle. The preset speed prediction model can be a prediction model based on machine learning or a prediction model based on a neural network.

[0150] Step 924, determining the driving direction of the vehicle according to the lane information.

[0151] In some embodiments, after determining the assisted driving information, the vehicle implements assisted driving based on the assisted driving information. Specifically, the vehicle's current driving speed and a preset target driving direction can be obtained. If the current driving speed does not match the target driving speed, and / or the target driving direction does not match the driving direction, a prompt message is output to prompt the vehicle to drive according to the assisted driving information.

[0152] Exemplarily, when the preset target driving direction of the vehicle does not match the driving mode, a "wrong lane" prompt message is output to prompt the driver of the vehicle to change lanes and drive in the correct lane.

[0153] Exemplarily, when the current driving speed of the vehicle is greater than the target driving speed, a prompt message of "You are speeding, please slow down" is output to prompt the driver of the vehicle to slow down.

[0154] In some embodiments, the auxiliary driving information also includes road condition information. Traffic data of the driving road is determined according to the road surface information, road condition information of the driving road is determined according to the traffic data, and the road condition information is determined as the auxiliary driving information.

[0155] For example, taking the driving environment in fog as an example, when a vehicle rear-end collision occurs on the driving road, the road central control unit generates road information and writes the road information into the road NFC reader. After the vehicle on the driving road obtains the road information, if it receives a rear-end collision in front, it changes lanes to avoid a secondary rear-end collision.

[0156] The assisted driving implementation method provided in the embodiment of the present application reads road surface information and lane information from a road surface NFC reader / writer deployed on the driving road surface through an on-board NFC reader / writer deployed at the bottom of the vehicle, generates assisted driving information based on the road surface information and lane information, and implements assisted driving based on the assisted driving information. It is not restricted by GPS / GPRS, and even when the network conditions are not good, the road surface information of the driving road surface can be obtained, and sudden situations on the driving road surface can be identified in time, thereby reducing the driving safety risks caused by untimely acquisition of road surface information and improving driving safety.
