Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the following embodiments and accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.

It should be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and/or processing steps closely related to the scheme according to the present invention are shown in the drawings, and other details not so relevant to the present invention are omitted.

It should be emphasized that the term "comprises/comprising" when used herein, is taken to specify the presence of stated features, elements, steps or components, but does not preclude the presence or addition of one or more other features, elements, steps or components.

In the existing ETC charging system, there are some problems that influence the traffic and the charging, including: accurate path charging cannot be completely realized, and the charging amounts of multiple passes are not completely consistent, possibly causing complaints of users; the ETC portal data writing method has the advantages that the vehicle running speed is high, the written data are more, the transaction time is increased, the ETC portal data writing fails or cannot be written in time, and the portal transaction success rate needs to be improved; the probability of reverse identification of the portal is high due to the problems of inconsistent sensitivity of an On Board Unit (OBU), regional control of a Road Side Unit (RSU) and the like, and abnormal charging is caused; the transaction success rate is low, and the ETC entrance and exit toll station passing efficiency is low due to abnormal vehicle processing; there are signal interference problems such as adjacent lane interference, truck reflection, message board reflection, etc. Some of these problems are caused by the fact that the protocol mechanism of the ETC itself does not support, some of the problems are determined by the communication area and frequency band characteristics of the ETC device, and the problems cannot be solved completely and reliably only by the ETC itself, so that a new technology needs to be introduced to solve the problems.

At present, the technology of the Vehicle-road cooperative system V2X (Vehicle-To-evaporating) is developed rapidly, and the relevant standard specification is mature. In view of the characteristics of relatively flexible communication mechanism and large communication area of the V2X, the V2X technology has great advantages when applied to the charging field. However, the direct application of the V2X technology to the highway closed charging mode in the existing mode also has certain disadvantages, the V2X antenna adopts an omnidirectional antenna, the radiation range is wide, the communication area is large, the range of the communication area cannot be accurately controlled, and the problem of maloperation is easily caused, which is particularly shown in the following steps: entrance information is easily wrongly written into vehicles passing by the highway entrance toll station, so that subsequent ETC portal frame mis-transaction and exit mis-charging are caused; the ETC toll gate frame is easy to wrongly write portal frame information and charging information to vehicles running oppositely or nearby other vehicles running at high speed, so that abnormal charging is caused; the vehicle normally running on the main road of the exit toll station or vehicles at other exits nearby are easy to be charged by mistake. Aiming at the problems, the invention provides a highway toll collection method and a highway toll collection device, which are used for realizing read-write transaction based on a V2X antenna, ensuring the accuracy and success rate of transaction and avoiding error transaction.

It should be noted that the present invention is implemented by introducing a V2X technology to the existing ETC lane system, and specifically, in the highway traffic process, V2X antennas are arranged on the entrance lane, the toll gate frame and the exit lane, and are connected with corresponding lane controllers. The communication distance of the V2X antenna is longer, and in the lane traveling direction, the vehicle normally establishes communication with the V2X antenna first and then with the ETC antenna. The communication area of each V2X antenna is demarcated as a V2X transaction area. Accordingly, an on-board unit provided with a V2X communication module is used, as shown in fig. 1, including at least a V2X communication module, an ETC communication module, a control unit module, a security module, and a positioning module. The on-board unit is mounted on the user's vehicle and communicates over a relatively long distance with the V2X antennas of the entrance, toll gate and exit lanes during highway driving. Further, the entrance lane is provided with a first V2X antenna and a first ETC antenna, toll gate frames are provided on the sections of the expressway, each toll gate frame is provided with a second V2X antenna and a second ETC antenna, and the exit lane is provided with a third V2X antenna and a third ETC antenna. The first V2X antenna, the second V2X antenna and the third V2X antenna are communicated based on a vehicle-road cooperative system, and the communication distance can reach hundreds of meters. The first ETC antenna, the second ETC antenna and the third ETC antenna may communicate based on a dedicated short range communication protocol (DSRC) with a communication distance of less than 10 meters.

In particular, the invention provides a highway toll method for operating on an on-board unit comprising at least a V2X communication module, an ETC communication module, a control unit module, a security module and a positioning module. The V2X communication module processes a V2X signal of 5.9GHz, and realizes communication with a V2X antenna. The ETC communication module processes DSRC signals of 5.8GHz, and communication with the ETC antenna is achieved. The control unit module provides functions of data processing, instruction control and the like. The security module is an ESAM module and is used for storing security information such as charging related files, keys and the like. The satellite positioning module provides positioning information such as longitude and latitude positions, driving directions and the like.

Further, the method comprises steps S101 to S113:

Step S108: and returning second ETC information according to the pre-reading instruction sent by the second V2X antenna, calculating the first transaction fee amount, performing pre-transaction, generating first pre-transaction result information and sending the first pre-transaction result information to the second V2X antenna.

Step S109: and returning a second vehicle-mounted unit number according to a pre-reading instruction sent by a second ETC antenna in the toll gate frame, so that the toll gate frame inquires corresponding first pre-transaction result information according to the second vehicle-mounted unit number, and if the first pre-transaction result information shows that the pre-transaction is successful, the toll gate frame passes.

Step S110: at the exit lane, third toll service information broadcasted by a third V2X antenna in the exit lane according to a fourth set period is received, the third toll service information including at least an exit toll direction and an exit V2X transaction area.

Step S111: and determining the position and the driving direction of the vehicle according to the vehicle positioning information, and if the driving direction of the vehicle is consistent with the exit charging direction and is in the exit V2X transaction area, sending third reply information containing the vehicle identification to a third V2X antenna by the V2X communication module.

Step S112: and returning third ETC information according to the pre-reading instruction sent by the third V2X antenna, calculating a second transaction fee amount, generating second pre-transaction result information, sending the second pre-transaction result information to the third V2X antenna, and directly deducting the fee when the second pre-transaction result information shows that the transaction is successful by the third ETC antenna of the exit lane.

Step S113: and returning a third vehicle-mounted unit number according to a pre-reading instruction sent by a third ETC antenna so that the exit lane can inquire corresponding second pre-transaction result information according to the third vehicle-mounted unit number, and if the second pre-transaction result information shows that the pre-transaction is successful, deducting the fee according to the second transaction fee amount and carrying out the rod-raising and releasing.

The first ETC information, the second ETC information and the third ETC information at least comprise vehicle information, card sign basic information and entrance and exit information.

In step S101, the vehicle-mounted unit continuously broadcasts basic safety messages according to a first set period during driving, so as to receive and record the basic safety messages in the entrance lane, the toll gate and the exit lane, and initiate a traffic read-write process. The first setting period can be determined according to the highest speed limit of the expressway and the transaction read-write range of each V2X antenna, the faster the vehicle running speed or the smaller the transaction read-write range of V2X, the shorter the first setting period, and the specific duration of the first setting period can be set independently according to different use scenes.

In step S102, when the vehicle passes through the V2X communication area of the entrance lane, a first toll service message transmitted from the first V2X antenna is received to indicate the entrance toll direction of the entrance lane and the range of the entrance V2X transaction area.

In step S103, the on-board unit may determine the current vehicle position and driving direction according to the vehicle positioning information generated by the positioning module, and if the current vehicle position and driving direction are consistent with the entrance charging direction and within the entrance V2X trading area, may send a first reply message to initiate a pre-trading process based on the V2X system. The pre-transaction flow is consistent with the conventional ETC communication flow, and specifically, at an entrance lane, the pre-transaction flow mainly comprises the steps of reading the contents of vehicle information, card information and the like recorded in the vehicle-mounted unit and writing the entrance information.

In step S104, the communication with the on-board unit is performed by the first V2X antenna prior to the first ETC antenna in a longer distance, performing pre-reading and pre-transaction. Since no cost is incurred at the entrance lane, it is only necessary to write the entrance information after actually reading the first ETC information. In some embodiments, the validity of the vehicle-mounted unit and the loaded card tag may be determined first, for example, the validity of information such as the loading state of the card tag, whether the vehicle belongs to a blacklisted vehicle, and the balance of the card tag is determined, if the vehicle-mounted unit and the loaded card tag are valid, entry information is written, and if the vehicle-mounted unit and the loaded card tag are invalid, the operation is not performed, and a prompt is performed.

In some embodiments, the card signature validity information recorded in the first ETC information indicates that the vehicle-mounted unit is detached, the user card is not in the validity period, the balance is insufficient or the account is abnormal, and then the first warning information returned by the first V2X antenna is received, and voice or text prompt is performed according to the first warning information.

In step S105, when the vehicle approaches the entrance lane, the vehicle enters the transaction communication range of the first ETC antenna, the first ETC antenna reads the first vehicle-mounted unit number from the vehicle-mounted unit and inquires the corresponding entrance information writing result, and if the information is written, the vehicle is directly released without operation. If not, the writing can be carried out again or an alarm prompt is carried out.

In step S106, in this embodiment, a sectional charging manner is adopted, and when passing through the toll portal, the toll amount of the corresponding road section is calculated by the toll portal respectively, and a charging operation is performed. Within the communication range of the second V2X antenna, the on-board unit may receive a second toll service message to confirm the direction of the portal toll and the portal V2X transaction area.

In step S107 and step S108, when the on-board unit determines that the vehicle position and the driving direction are consistent with the portal charging direction and within the portal V2X trading area, it transmits second reply information containing the vehicle identification to the second V2X antenna to initiate the pre-trading. In this embodiment, the second V2X antenna performs pre-transaction with the on-board unit, where the pre-transaction may include determining validity of the on-board unit and the card tag, reading vehicle information, card tag basic information, entrance/exit information, and payment information, calculating transaction fee amount of a corresponding road segment, and performing read/write transaction.

In step S109, when the vehicle approaches the toll gate, the second on-board unit number is read by the second ETC antenna in the toll gate, and the first pre-transaction result information is queried, and if the pre-transaction is successful, the vehicle is released, and if the pre-transaction is unsuccessful, the read-write transaction is performed again by the second ETC antenna.

In step S110, while the vehicle passes through the exit lane, the on-board unit may receive a third toll service message to confirm the exit toll direction and the exit V2X transaction area within the communication range of the third V2X antenna.

In steps S111 and S112, the on-board unit of the user vehicle transmits a third reply message to the third V2X antenna to initiate the pre-transaction when it is determined that its driving direction coincides with the exit charging direction and is within the exit V2X transaction area. And the third V2X antenna and the vehicle-mounted unit carry out pre-transaction, wherein the pre-transaction can comprise the judgment of the validity of the vehicle-mounted unit and the card tag, the reading of vehicle information, card tag basic information, entrance and exit information and payment information and the calculation of the transaction fee amount of a corresponding road section.

In step S113, when the vehicle travels near the exit lane, the third on-board unit number is read by the third ETC antenna in the exit lane, and the second pre-transaction result information is queried, and if the pre-transaction is successful, the vehicle is released, and if the pre-transaction is unsuccessful, the read-write transaction is performed again by the third ETC antenna.

In some embodiments, determining the vehicle location and direction of travel from the vehicle location information comprises: and acquiring vehicle positioning information corresponding to a plurality of continuous time points, and judging the area where the vehicle is located and the driving direction of the vehicle according to the vehicle position of each time point.

In other embodiments, a more precise positioning range may be set, for example, a plurality of positioning points or positioning areas are set along a predetermined lane, and the route and positioning accuracy formed by the corresponding positioning points or positioning areas should be able to distinguish different lanes, and also distinguish main roads and auxiliary roads, so as to achieve accurate lane route positioning. The number of positioning points or positioning areas may be set to 4 to 5 according to the layout of the entrance lane or the exit lane, and in the case where the lanes are complicated, a larger number may be set for higher accuracy. Correspondingly, the positioning modes of the entrance lane, the toll gate frame and the exit lane are consistent.

Illustratively, the first V2X antenna is continuously positioned to determine whether the vehicle is driving to the area of the toll station, and to avoid mischarging the vehicle on the side road or the vehicle driving to the side road. If the positions of the vehicle-mounted units are continuously positioned, if 5 positions can continuously determine that the vehicle drives to the lane of the toll station, and route judgment errors cannot occur, pre-transaction communication is carried out by adopting the first V2X antenna. When the vehicle travels to the ETC toll island, the ETC antenna performs a simplified transaction.

In some embodiments, after receiving the read-ahead command sent by the first V2X antenna in step S104, the method further includes: and returning first ETC information containing effective entrance information to the first V2X antenna based on the pre-reading instruction so as to prompt the first V2X antenna to stop operating.

In the present embodiment, if the in-vehicle unit has been written with valid entry information, the first V2X antenna is not operated.

In practical applications, there may be a case of poor communication, which may cause the first ETC antenna to first perform communication reading and writing with the on-board unit, and if the entry information has been written by the first ETC antenna, the first V2X antenna is no longer operated.

Accordingly, at the toll gate and exit lane, if the second ETC antenna is pre-transacted before the second V2X antenna, or the third ETC antenna is pre-transacted before the third V2X antenna due to communication problems, the corresponding second V2X antenna or third V2X antenna is not processed.

In some embodiments, after step S104, that is, after returning the entry information writing result according to the pre-read command sent by the first ETC antenna in the entry lane, the method further includes: and if the entry information writing result shows that the writing fails, receiving the entry information sent by the first ETC antenna to rewrite the entry information.

In some embodiments, in step S109, after returning the second onboard unit number according to the pre-read command sent by the second ETC antenna in the toll gate, so that the toll gate queries the corresponding first pre-transaction result information according to the second onboard unit number, the method further includes: and if the first pre-transaction result information shows that the transaction fails, returning second ETC information according to a reading instruction sent by a second ETC antenna, and calculating the first transaction fee amount and performing the transaction.

In some embodiments, in step S113, returning the third onboard unit number according to the pre-read command sent by the third ETC antenna in the exit lane, so that after the exit lane queries the corresponding second pre-transaction result information according to the third onboard unit number, the method further includes: and if the second pre-transaction result information shows that the transaction fails, returning third ETC information according to a reading instruction sent by a third ETC antenna, and calculating a second transaction fee amount and performing the transaction.

In some embodiments, the first V2X antenna generates and maintains a first on-board unit pre-transaction information table for recording the entry information writing result; the second V2X antenna generates and maintains a second vehicle-mounted unit pre-transaction information table for recording first pre-transaction result information; a third V2X antenna generates and maintains a third vehicle-mounted unit pre-transaction information table for recording second pre-transaction result information; the first pre-trading result information and the second pre-trading result information at least comprise the number of the vehicle-mounted unit participating in the trading, the pre-trading time and the trading result.

The on-board unit houses a satellite positioning module 150. The on-board unit periodically broadcasts basic safety messages containing vehicle identification, vehicle position, vehicle driving direction and the like according to the V2X application layer related standard.

The following description will proceed with specific embodiments of the present embodiment, taking an entrance toll station, an ETC toll gate frame, and an exit toll station as examples.

(1) Entrance toll station

The lane layout of the entrance tollgate is shown in fig. 2. The first V2X antenna may be installed under the roof of the toll lane or may be installed on the side of the square area in front of the entrance lane. The first V2X antenna communication area is large and can reach hundreds of meters farthest, the first ETC antenna communication area is only about less than 10 meters, and therefore before the vehicle drives into an ETC lane entrance, the first V2X antenna can communicate with the vehicle-mounted unit before the first ETC antenna. The communication area of the first V2X antenna sets the V2X transaction area. Vehicles passing through the V2X transaction area have only the only route to the toll station. In the figure, the V2X trading area is arranged on a necessary road to be driven to the toll station, and non-target trading vehicles at other positions such as a highway auxiliary road are excluded by the arrangement mode. Referring to FIG. 4, the specific process flow is as follows 1.01-1.10:

1.01 vehicles travel towards entrance toll station, the vehicle-mounted unit periodically broadcasts basic safety information containing vehicle identification, vehicle position, vehicle traveling direction and the like.

1.02 first V2X antenna continuously receives basic safety messages broadcast by the on board unit.

1.03 at the same time, the first V2X antenna periodically broadcasts a toll service message containing antenna identification, toll booth number, toll direction, V2X transaction area, etc.

The method comprises the steps that 1.04 vehicle-mounted units continuously receive charging service messages broadcasted by a first V2X antenna, whether vehicles are in a V2X transaction area or not is judged according to multiple positioning information of the vehicles, the driving direction of the vehicles is consistent with the charging direction, when the vehicles pass the judgment, the messages containing contents such as vehicle identification, vehicle positions and basic information of the vehicle-mounted units are replied to the first V2X antenna, and if not, the messages are not replied.

1.05 the first V2X antenna receives the reply message from the on board unit and executes the pre-transaction process.

1.06 when executing the pre-transaction process, the first V2X antenna should first read the ETC file information of the on-board unit, determine the passing validity of the on-board unit and the ETC file information, then determine whether the on-board unit has the entrance information, if the entrance information already exists and the entrance information is legal, end the process, and do not perform the entrance writing operation any more.

1.07 for a vehicle-mounted unit without entrance information, a first V2X antenna refers to a typical operation flow of an ETC entrance, judges through a lane background execution state list, a pursuit payment list, balance and the like, and writes entrance information if the vehicle-mounted unit passes the judgment; and for the failure of pre-transaction caused by abnormal equipment and account of the user, such as the vehicle-mounted unit is detached, is not in the validity period, is in the state list, and the license plate is in the reimbursement list, the vehicle-mounted unit carries out corresponding abnormal voice or text prompt on the user so as to guide the vehicle to drive into the mixed lane in advance.

1.08 after the entry information is successfully written, the on-board unit masks for a period of time the charging information of the first V2X antenna with which the transaction is completed.
