In order to enable technical problems, technical solutions, and beneficial effects of the present application to be clearer and more understandable, the present application will be further described in detail hereinafter with reference to the drawings and embodiments. In the description of the application, the terms “first” and “second” are used only for purposes of distinguishing description, and are not understood to indicate or imply the relative importance.
In order to illustrate the technical solutions disclosed in the present application, the technical solutions of the present application are described with reference to detailed embodiments below.
S21, receiving shared information and a usage smart contract which are sent by a vehicle owner client.
In the embodiment provided by the present application, the server receives the shared information and the usage smart contract sent by the vehicle owner client, wherein the vehicle owner client is configured for receiving the information of the shared vehicle input by the vehicle owner of the shared vehicle and identity information of the vehicle owner, then the vehicle owner client is sending the information of the shared vehicle and the identity information of the vehicle owner to the server. The above-mentioned information of the shared vehicle includes information, such as the license plate number, the vehicle driving license, auto age, and the operation status of the engine, the running state of security devices and electronic devices and driving mileage and the like. The identity information of the vehicle owner includes one of, or more than one of the name of the vehicle owner, the identity number, contact information, etc. The usage smart contract specifies using rules for the shared vehicle, including a charging rule for using the shared vehicle, payment information, etc.
S22, registering the shared information and the usage smart contract into a block chain network and radioing the shared information and the usage smart contract in the entire network of the block chain.
The server sends the received shared information and the usage smart contract to the block chain network device, the block chain network device registers the shared information and the usage smart contract in the block chain and radios the shared information and the usage smart contract in the entire network of the block chain. Alternatively, when the server itself is a node device of the block chain, the server directly registers the received shared information and the usage smart contract in the block chain and radios to the entire network of the block chain, so that other block chain network devices may also obtain the same information, and indicating the other block chain network devices to store the received information. Optionally, when the server is sending the shared information and the usage smart contract to the block chain network, the shared information and the usage smart contract can be packaged before sending.
S23, receiving a rental request sent by a rental client and registering the rental request into the block chain network, wherein the rental request comprises personal information and rental requirements of a user initiating the rental request.
The server waits to receive the rental request sending by the rental client, if receiving the rental request, the server registers the rental request into the block chain network. The rental request includes personal information and rental requirements of the user sending the rental request. The personal information includes personal identifier, driving behavior preferences and the like, and the rental requirements includes information, such as vehicle type preferences, location information, cost budget information, etc.
S24, calculating a user grade of the user initiating the rental request according to a credit smart contract pre-stored in the block chain and the personal information.
After receiving the rental request, according to the personal identifier in the rental request, the server acquires specific user information such as driving behavior information, traffic violation information, driving mileage information, transaction information of using a shared vehicles, etc, stored in the block chain network. According to the specific user information mentioned above, the user grade of the user is calculated, wherein the user grade includes the user credit rating and driving levels, simultaneously considering together with the rental request from the user to find a matched shared vehicle.
Specifically, according to the ratio of the driving mileage of the user to violation behaviors or violation information within the driving mileage (e.g. corresponding violation behaviors or violation behavior times within 1000 kilometers of driving mileage), the credit rating can be determined. For example, it is provided that the basic credit rating of the user is average, and the user information shows that the user has a long driving mileage with no violation behaviors within the driving mileage and no traffic violation information, then it can be determined that the credit rating of the user is merit. If the user information shows the driving mileage of the user is short with no illegal behaviors within the driving mileage and no traffic violation information, or the ratio of the driving mileage of the user to the driving violation behaviors maintains in a low level. (e.g. the number of corresponding illegal behaviors or traffic violation behaviors is within 5 times within 1000 kilometers of driving mileage), then it may be determined that the credit rating of the user is average. If the user information shows the ratio of the driving mileage to the illegal behaviors and traffic violation information is relatively high (e.g. the number of corresponding illegal behaviors or traffic violation behaviors is more than 10 times within 1000 kilometers of driving mileage), then it is determined that the credit rating of the user is poor.
Specifically, according to the driving mileage and driving behavior information, the driving rating of the user can be determined. The longer the driving mileage with the fewer number of driving violation in corresponding driving behavior information, the driving rating of the user will be higher.
S25, searching matched shared vehicles according to the user grade and the rental requirements.
The calculated user grade (credit rating and driving level) can be used to determine the range of the matched shared vehicle of the user, including a charging range, a vehicle type range, and the like, and considering together with the rental requirements of the user, such as vehicle type preferences, location information, cost budget, etc, the matched shared vehicle is determine, so that the information of the matched shared vehicle is provided to the user.
S26, sending the matched shared vehicles to the rental client so that the rental client determines a target shared vehicle.
S27, releasing usage authorization of the target shared vehicle to the rental client.
According to the calculation of the user grade of the user initiating the rental request, searching proper shared vehicles among shared vehicles, and sending the information of the found target share vehicles to the rental client for the user to select. If receiving the selection information of target share vehicle sending from the rental client, then the usage authorization of the target shared vehicle is released to the user. Specifically, the specific manner of releasing the usage authorization of the target shared vehicle to the user can be directly controlling the target shared vehicle doors to be unlocked, and the engine to be in an available state. Alternatively, controlling password of the target shared vehicle also can be sent to the rental client, and according to the controlling password, the user unlocks the vehicle doors and starts the engine, so as to obtain the usage authorization of the shared vehicle.
It should be noted that, the above-mentioned data is stored in the block chain network in a form of a block. Each block comprises two parts, a block header and a block body, wherein the block header is configured to record characteristic values of the current block, and the block body is actual data. The block header includes a plurality of characteristic values of the current block. The plurality of characteristic values comprises: generating time, the hash value of the block body and the hash value of the last block. The hash value of a block is calculated according to the block header. That is, each of the characteristic values of the block header is sequentially connected together to form a long character string, and then calculating the hash value of the character string, thus the hash value of each block is not the same, identifying the block via hash.
Since block header contains many contents, the contents include a hash of the current block body and the hash of the last block. Since the consensus mechanism of the block chain, modifying a plurality of blocks within a short time is almost impossible to happen, unless more than 51% of the computing ability of the entire network of the block chain is mastered. So that de-centering and non-tampered characteristics of the block chain are formed.
Thus, in the embodiment of the present application, utilizing the de-centering and non-tampered characteristics of the data in the block chain, information of usage data and transaction data and other information produced in the process of the vehicle rental is sent to the node devices of the block chain for storage, which guarantees that the vehicle owner obtains the true vehicle usage data and transaction data, so that the vehicle owner can share the vehicle to others through a service platform in a block chain with confidence.
Additionally, the smart contract is a executable computer program which can execute contract clauses automatically. It does not generate smart contract, and will not modify the smart contract; its presence is only intended to correctly perform a group of complex digitized commitments with trigger conditions according to the will of the participants. Thus, after the smart contract deployed in the block chain, the smart contract waits to be called, but cannot be changed.
A large number of smart contracts are typically deployed in the block chain, wherein the smart contract is with an identifier for identifying the smart contract. Alternatively, the identifier of the smart contract may be the name of the smart contract, and the identifier is configured to uniquely identify the smart contract deployed in the block chain. Thus, information sent by the user terminal to the block chain may carry identifiers of different smart contracts, so that after the block chain network received relevant data carrying the identifier information of the smart contracts, corresponding smart contract may be called to execute corresponding program.
Optionally, in another embodiment provided by the present application, before the receiving shared information and the usage smart contract sent by the vehicle owner client, the method for managing shared vehicles further includes:

In this embodiment, in order to encourage more owners to share their own vehicles, the server will release the service protocol of the shared vehicle in advance so as to guide the vehicle owner to submit the shared information and usage smart contract according to the service protocol. For example, the basic requirements of the shared vehicle (such as the vehicle age, the driving route and the like) of the shared vehicle can be specified in the service protocol, and the requirements for the vehicle owner authentication (such as what information can only be used for authenticating the identity of the vehicle owner) and the like.
Optionally, the server can also install the vehicular terminal for the shared vehicle whose vehicle owner is passed the authentication, wherein the service protocol may further comprise a request manner for installing the vehicular terminal, a charging rule for installing the vehicular terminal and the like. In addition, the service protocol is further used for informing the vehicle owner that running data of the shared vehicle will also be registered into the block chain network. The server issues the service protocol and specifies a service smart contract according to the service protocol, so as to conveniently send a check for the shared information to the vehicle owner hereinafter. The server registers the issued service protocol and the service smart contract in the block chain network.
Optionally, in another embodiment provided by the present application, the shared information comprises the identity information of the vehicle owner, and after said shared information and the usage smart contract sent by the vehicle owner client is received, the method further comprises:
