Detailed Description

The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

As shown in fig. 1, the present application provides a method for processing traffic information, comprising the following steps:

s101: broadcasting the charging information;

s102: receiving encrypted payment approval information of the target vehicle, the encrypted payment approval information being response information of the charging information;

s103: generating consumption information of the target vehicle in a case where the encrypted payment approval information is verified to be valid;

s104: and charging the target vehicle according to the consumption information.

The above method may be performed by a Road Side Unit (RSU), for example, the Road Side Unit may be a high speed charging/billing device, a parking lot charging/billing device, and the like. The RSU has a unique road side device Key (RSU Key), and may be stored in a Security Chip (SE) of the RSU, for secure access.

The roadside unit also includes a charging Certificate (TC Cert). The charging certificate is an application certificate of Vehicle wireless communication (V2X), and the charging certificate also states that the road side unit has charging capability and also includes information such as charging location. The toll location indicates that the roadside setting can only charge within the toll location. The toll collection position can be used for anti-counterfeiting, for example, if the toll collection position received by the target vehicle to the road side unit is an area A, and the current position of the target vehicle is an area B, the road side unit can be determined to be a forged road side unit.

In this embodiment, the charging certificate and the roadside device key may be used as a public key and a private key of the roadside device to implement an asymmetric encryption algorithm.

Taking an expressway as an example, a roadside unit at an entrance of the expressway broadcasts charging information loaded with a charging certificate. For example, the charging information may be signed with a charging certificate, and the signed charging information may be broadcast. The manner of broadcasting may include V2X signals transmitted using Dedicated Short Range Communication (DSRC), cellular link Communication (LTE-V-Cell), Short Range Direct link Communication (LTE-V-Direct), 5G Communication, and the like.

Referring to fig. 2, when a target vehicle enters a highway entrance, an On Board Unit (OBU) of the target vehicle receives and verifies the charging information. The verification may include decoding the charging information to obtain the charging certificate. And determining whether the charging information is valid by judging the authenticity of the charging certificate. In the event that the charging information is determined to be valid, the target vehicle may broadcast the encrypted payment approval information. Likewise, payment approval information may also be transmitted via the V2X signal.

Still taking the highway scenario as an example, the road side unit at the entrance of the highway receives the encrypted payment permission information broadcast by the target vehicle, decrypts the payment permission information and starts to charge after the verification is passed. The charging may be based on the distance traveled by the target vehicle, or the charging may be based on time, etc. Charging information can be shared between the road side units at different positions, for example, the road side units at different positions can be interconnected through a cloud server, or the road side units can be interconnected with each other as nodes in the internet of things.

In an expressway scene, when a target vehicle leaves the expressway, the road side unit at the exit of the expressway broadcasts the charging information loaded with the charging certificate. And under the condition of information interaction with the target vehicle and passing verification, determining consumption information of the target vehicle according to the position of the target vehicle entering the expressway.

Further, a fee deduction may be made in an account already authorized by the target vehicle based on the consumption information to effect a fee collection for the target vehicle.

The method may be performed in a roadside unit. Alternatively, the above method may be performed by the road side unit and the cloud, respectively, for example, the road side unit broadcasts charging information, and the cloud performs consumption information and charging fee of the target vehicle.

By the scheme, the road side unit and the target vehicle can be based on wireless communication (especially V2X) and finally realize payment, and the problem of relying on image recognition in the prior art is overcome. And because the road side unit and the target vehicle can realize payment by using fewer interaction times, the efficiency is improved.

As shown in fig. 3, in one embodiment, the determination that the encrypted payment approval information is valid includes:

s301: decrypting the encrypted payment permission information to acquire a payment certificate and signature information of the target vehicle;

s302: in case that the payment certificate and the signature information are verified, it is determined that the encrypted payment approval information is valid.

The target vehicle decrypts the received charging information broadcasted by the road side equipment, so that the charging certificate can be obtained, and information such as the charging position and the like declared in the charging certificate can be obtained. The charging certificate is verified by using a predetermined rule (e.g., a root certificate issued by a certificate issuing authority). If the verification passes, a Data Key (OBU DEK, OBU Data Encryption Key) of the (temporary) current vehicle (target vehicle) is generated.

The payment approval information may include: a charging certificate, first payment license Encryption information (Encrypted OBU Date), and second payment license Encryption information (Encryption OBU DEK).

The charging certificate is obtained from the broadcasted charging information.

The payment information (Pay info) may include: current Vehicle license plate Number and Vehicle Identification Number (VIN).

And signing the payment information by using a payment certificate (Pay Cert) previously applied by the current vehicle to obtain a signature (Signed Pay Info) of the payment information.

And encrypting the signed payment information and the payment certificate by using the data key of the current vehicle to obtain first payment permission encryption information. The signature payment information may be encrypted using a vehicle number, a vehicle identification code, or the like, and the present application is not limited thereto.

And encrypting the data key of the target vehicle by using the charging certificate to obtain second charging permission encryption information.

The roadside device receives the payment approval information, and may determine from the charging certificate that the payment approval information is a response as the charging information. Therefore, the second payment permission encryption information can be decrypted by using the road side device Key (RSU Key) to obtain the data Key (OBU DEK) of the target vehicle.

Next, the first payment approval encryption information is decrypted using the data key of the target vehicle, the signature of the payment information, and the payment certificate.

The payment certificate is verified using a predetermined rule, such as the root certificate of the certificate issuing authority. And in the case of passing the verification, verifying the signature of the payment information by using the payment certificate. And in the case of passing the re-verification, determining that the payment permission information is valid payment permission information. Therefore, the target vehicle can be confirmed and charged according to the vehicle information such as the license plate number, the vehicle identification code and the like.

Through the scheme, the target vehicle can be verified to be authentic and credible by verifying the information of the target vehicle, and the condition that the fake plate cannot be distinguished when charging is carried out by depending on the image is avoided.

As shown in fig. 4, in one embodiment, generating consumption information for a target vehicle includes:

s401: generating billing information of the target vehicle according to the payment permission information, wherein the billing information comprises information of starting billing and information of ending billing of the target vehicle;

s402: and determining the cost to be paid of the target vehicle according to the charging information, and taking the cost to be paid as consumption information.

As mentioned above, the roadside apparatus may be disposed at various locations, such as an entrance of a highway, an exit of a highway, a rest station of a highway, etc., or at an entrance of a parking lot, an exit of a parking lot, etc.

The roadside apparatus at different locations may perform different functions, for example, the roadside apparatus provided at an entrance of a highway or a parking lot may perform a function of starting billing. When the payment permission information of the target vehicle is received, the time when the target vehicle enters or the place where the target vehicle enters is recorded. The roadside apparatus disposed at the rest station of the expressway performs a function of dotting the position, and the roadside apparatus disposed at the exit of the expressway or the parking lot performs a function of ending the billing and calculating the amount of money.

Taking the roadside apparatus disposed at the entrance of the highway as an example, in the case where valid payment permission information of the target vehicle is received, the current position of the roadside apparatus may be set as a place where the target vehicle travels. In addition, taking the roadside apparatus provided at the entrance of the parking lot as an example, in the case where valid payment permission information of the target vehicle is received, the time at which the information is received may be taken as the time at which the target vehicle enters.

On the other hand, when the target vehicle is driven away from the highway or the parking lot, the roadside device arranged at the exit of the highway or the exit of the parking lot may query the driving-in position or the driving-in time of the target vehicle according to the internet of things when receiving valid payment permission information of the target vehicle, so that the fee to be paid for the target vehicle may be determined in combination with the driving-out position or the driving-out time of the target vehicle. The fee to be paid can be used as consumption information.

In an embodiment, the above process may also be implemented by a cloud charging server in communication with the roadside device, that is, the cloud charging server may receive and store the time and/or the place at which the target vehicle starts charging. In case that the time and/or place where the target vehicle ends billing is received, the fee to be paid of the target vehicle may be determined in conjunction with the time and/or place where billing starts.

By the scheme, the charge to be paid of the vehicle can be determined by utilizing the driving-in and driving-out information of the vehicle, and the charging can be realized without depending on image acquisition.

In addition, in an embodiment, before the step S401 is executed, a step of performing secondary verification on the payment certificate and the signature information of the target vehicle may be executed first. The second verification may be further to see if the certificate is expired and/or if the certificate is still registered, etc., in case the certificate has been confirmed as genuine.

The calculation may serve as an identification of the target vehicle. Further, other payment approval information such as the license plate number and the vehicle identification code may be calculated to obtain the calculation result. And will not be described in detail herein.

The billing information of the target vehicle may include information such as the amount of consumption of the target vehicle. And encrypting the bill information and the charging certificate of the target vehicle to generate encrypted bill information.
