Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Reference in the specification to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the specification. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The installation identification method of the vehicle-mounted terminal can be applied to the application environment shown in fig. 1. The vehicle-mounted terminal can be mounted on a vehicle, and after the mounted vehicle is started, the vehicle-mounted terminal can acquire a vehicle identification code of the mounted vehicle and perform fusion processing on the vehicle identification code of the mounted vehicle and a terminal identification code of the vehicle-mounted terminal to obtain a fusion code of the mounted vehicle and the vehicle-mounted terminal; wherein, different vehicle identification codes correspond to different vehicle identification code types. Further, the vehicle-mounted terminal can also send the fusion code to the Internet of vehicles platform for storage.
After a current vehicle provided with the vehicle-mounted terminal is started, the vehicle-mounted terminal can acquire at least two vehicle identification codes of the current vehicle, wherein different vehicle identification codes can correspond to different vehicle identification code types; the vehicle-mounted terminal further acquires a terminal identification code of the vehicle-mounted terminal, and performs fusion processing on the vehicle identification code and the terminal identification code to obtain a current fusion code of the current vehicle and the vehicle-mounted terminal; and identifying whether the current vehicle is the target vehicle or not according to the consistency of the current fusion code and the target fusion code of the target vehicle, wherein the target vehicle can be a vehicle bound with the vehicle-mounted terminal.
In one embodiment, as shown in fig. 2, an installation identification method of a vehicle-mounted terminal is provided, which is described by taking the method as an example applied to the vehicle-mounted terminal in fig. 1, and includes the following steps:
step S201, the vehicle-mounted terminal determines at least two vehicle identification codes aiming at the current vehicle; wherein, different vehicle identification codes correspond to different vehicle identification code types; the current vehicle is equipped with a vehicle-mounted terminal.
The vehicle identification codes can uniquely represent each trolley, and the same trolley can be provided with a plurality of vehicle identification codes of different types, namely, each vehicle identification code can correspond to different vehicle identification code types; illustratively, the vehicle identification code types may include, but are not limited to: VIN, SPID (Supported Parameters identification), CALID (Calibration identification, vehicle identification code, same vehicle type, fixed vehicle type), CVN (Calibration Verification Number, same vehicle type, fixed vehicle type), ESN (Engine Serial Number, same vehicle type and different vehicle types, the same vehicle type and different vehicle types may be the same), and the like, wherein each vehicle has a unique vehicle identification code corresponding to each type.
The vehicle-mounted terminal is installed to the current vehicle, and the vehicle-mounted terminal can gather two at least vehicle identification codes of current vehicle, and each vehicle identification code corresponds different vehicle identification code types, and for example the vehicle-mounted terminal can gather VIN sign indicating number and SPID sign indicating number.
Step S202, the vehicle-mounted terminal acquires a terminal identification code of the vehicle-mounted terminal.
The terminal identifier may uniquely represent the vehicle-mounted terminal, and may be written and determined during production of the vehicle-mounted terminal, along with the entire life cycle of the vehicle-mounted terminal, such as an International Mobile Equipment Identity (IMEI).
Step S203, the vehicle-mounted terminal obtains a fusion code of the current vehicle and the vehicle-mounted terminal as a current fusion code based on the fusion processing of the at least two vehicle identification codes and the terminal identification codes.
After the vehicle-mounted terminal obtains the vehicle identification code of the current vehicle, the vehicle identification code and the terminal identification code can be fused, and the fused code obtained through fusion is used as the current fused code.
Further, in order to ensure the reliability of the fusion code and reduce the risk of reverse cracking, the fusion processing mode can be hash operation; specifically, the vehicle-mounted terminal performs hash operation on at least two vehicle identification codes and the terminal identification code to obtain a hash value, and the hash value is used as the current fusion code.
Step S204, according to the consistency of the current fusion code and a target fusion code prestored in the vehicle-mounted terminal, the vehicle-mounted terminal identifies whether the current vehicle is a target vehicle; the target fusion code is a fusion code of the target vehicle and the vehicle-mounted terminal.
The target vehicle may refer to a vehicle bound with the in-vehicle terminal; when the vehicle-mounted terminal is installed in the target vehicle, the target fusion code of the target vehicle may be generated as in steps S201 to S203, and the target fusion code may be stored in the local terminal after the generation. After obtaining the current fusion code of the current vehicle, the vehicle-mounted terminal can compare the current fusion code with the target fusion code, judge whether the current fusion code is consistent with the target fusion code, and judge whether the current vehicle is the target vehicle according to a consistency result.
In one embodiment, since each vehicle identification code corresponds to a different vehicle identification code type, when the fusion processing in step S203 is performed, the vehicle-mounted terminal may select a different vehicle identification code type to fuse with the terminal identification code, so as to obtain a plurality of fusion codes, so as to further ensure the accuracy of the identification result. The method specifically comprises the following steps: the vehicle-mounted terminal acquires various fusion combinations; each fusion combination comprises a terminal identification code; and in any two fusion combinations of the multiple fusion combinations, one fusion combination comprises at least one vehicle identification code, and the type of the vehicle identification code corresponding to at least one vehicle identification code is different from the type of the vehicle identification code corresponding to the vehicle identification code comprised in the other fusion combination; furthermore, the vehicle-mounted terminal performs fusion processing on the identification codes in the same fusion combination, and a plurality of fusion codes are obtained after fusion processing of a plurality of fusion combinations is completed. Illustratively, the fused combinations may be as shown in table 1 below.
TABLE 1
The vehicle-mounted terminal respectively carries out fusion processing on the vehicle identification codes of the target vehicle and the current vehicle according to a plurality of fusion combinations, and then can obtain a plurality of target fusion codes and a plurality of current fusion codes, wherein each target fusion code corresponds to a different fusion combination, and each current fusion code corresponds to a different fusion combination.
When the vehicle-mounted terminal identifies whether the current vehicle is the target vehicle, the following steps can be executed: the vehicle-mounted terminal carries out consistency comparison on the target fusion code and the current fusion code corresponding to the same fusion combination, and corresponding comparison results (such as consistency or inconsistency) can be obtained; therefore, after the vehicle-mounted terminal finishes the comparison of the target fusion codes and the current fusion codes of all the fusion combinations, a plurality of comparison results can be obtained, and if the number of the comparison results is equal to or larger than the preset value, the vehicle-mounted terminal can identify the current vehicle as the target vehicle.
In the installation and identification method of the vehicle-mounted terminal, after the vehicle-mounted terminal is installed on the current vehicle, the vehicle-mounted terminal can acquire at least two vehicle identification codes of the current vehicle, which correspond to different vehicle identification code types, and perform fusion processing on the vehicle identification codes and the terminal identification codes to obtain a current fusion code of the current vehicle, and identify whether the current vehicle is a target vehicle according to the consistency of the current fusion code and the target fusion code; that is to say, the vehicle-mounted terminal can normally identify based on the fusion codes obtained by the at least two vehicle identification codes and the terminal identification codes, and accurately identify whether the current vehicle provided with the vehicle-mounted terminal is the target vehicle or not according to the consistency of the current fusion code and the target fusion code, so that the situation that whether the current vehicle is the target vehicle or not cannot be accurately identified due to the fact that the VIN cannot be read is avoided.
In one embodiment, when the vehicle-mounted terminal executes step S204, if it is determined that the current fusion code does not coincide with the target fusion code, it may recognize that the current vehicle is not the target vehicle, and replace the installed vehicle with the current vehicle as the vehicle-mounted terminal.
Further, after the vehicle-mounted terminal determines that the current vehicle is the replacement installation vehicle, replacement installation prompt information for the vehicle-mounted terminal can be sent to the user side bound with the vehicle-mounted terminal through the vehicle networking platform. If the vehicle-mounted terminal does not receive the replacement installation confirmation information returned by the Internet of vehicles platform, the vehicle-mounted terminal can further identify the current vehicle as a vehicle with abnormal replacement installation of the vehicle-mounted terminal; the replacement installation confirmation information is confirmation information aiming at the replacement installation prompt information and triggered by the user side, and is sent to the Internet of vehicles platform by the user side; if the vehicle-mounted terminal receives the confirmation information returned by the vehicle networking platform, the vehicle-mounted terminal can further identify the current vehicle as the vehicle which is normally replaced and installed by the vehicle-mounted terminal.
That is, if the current fusion code does not coincide with the target fusion code, it is interpreted that the in-vehicle terminal is mounted from the target vehicle to the current vehicle instead. In some scenarios, after the vehicle runs for a period of time, the vehicle owner may obtain compensation resources (e.g., vehicle component maintenance resources) for the vehicle from other parties based on the running data collected by the vehicle-mounted terminal; therefore, in order to cheat relevant resources, some vehicle owners replace and install the vehicle-mounted terminal from the target vehicle to other vehicles, and report the running data acquired by the vehicle-mounted terminal from the other vehicles to the vehicle networking platform as the running data of the target vehicle.
After the vehicle-mounted terminal is replaced and installed, if the vehicle owner confirms the replacement and installation, the driving data acquired by the vehicle-mounted terminal from the current vehicle cannot be reported to the Internet of vehicles platform as the driving data of the target vehicle, and the replacement and installation is normal, namely the current vehicle is the vehicle which is normally replaced and installed, and the condition that the vehicle owner fakes the driving data does not exist; if the vehicle owner does not confirm the replacement installation, the driving data acquired by the vehicle-mounted terminal from the current vehicle is reported to the Internet of vehicles platform as the driving data of the target vehicle, which indicates that the replacement installation is the abnormal replacement installation, namely, the current vehicle is the vehicle abnormally replaced and installed, and the vehicle owner can counterfeit the driving data.
In one embodiment, if the vehicle-mounted terminal does not pre-store the target fusion code, when receiving a binding instruction for the vehicle-mounted terminal sent by the user terminal, the vehicle-mounted terminal may locally store the current fusion code as the target fusion code, use the current vehicle as the target vehicle, and further send the target fusion code and the terminal identification code to the vehicle networking platform for storage.
In the above embodiment, when the vehicle-mounted terminal does not store the target fusion code, it is described that the vehicle-mounted terminal does not have a corresponding target vehicle, at this time, the user terminal may trigger the vehicle-mounted terminal to use the current vehicle as the target vehicle when sending the binding instruction, and store the current fusion code of the current vehicle as the target fusion code, so as to ensure that the target vehicle is a vehicle that the user terminal has confirmed, and avoid a situation that the vehicle-mounted terminal uses a vehicle that is not confirmed by the user terminal as the target vehicle.
In one embodiment, at least one vehicle identification code successfully read by the vehicle-mounted terminal exists in the at least two vehicle identification codes, so that the situation that the vehicle-mounted terminal cannot be bound due to data loss caused by reading failure is avoided.
Further, the in-vehicle terminal may include the following steps when executing step S201: the vehicle-mounted terminal determines a vehicle bus protocol of a current vehicle and determines the information of the success probability of reading the vehicle identification codes corresponding to various vehicle identification code types by the vehicle bus protocol. Then the vehicle-mounted terminal obtains the target vehicle identification code type from the multiple vehicle identification code types based on the reading success probability information, reads the vehicle identification code aiming at the current vehicle according to the target vehicle identification code type to obtain at least one vehicle identification code successfully read by the vehicle-mounted terminal, and obtains at least two vehicle identification codes aiming at the current vehicle based on the at least one vehicle identification code successfully read by the vehicle-mounted terminal.
Illustratively, the vehicle-mounted terminal determines that a vehicle bus protocol of the current vehicle is an On Board Diagnostics (OBD) protocol, and according to the reading success probability information of the vehicle identification code corresponding to the vehicle identification code type successfully read based On the OBD protocol, the target vehicle identification code type selected by the vehicle-mounted terminal from the plurality of vehicle identification code types may be at least one of VIN, SPID, CALID, CVN, or ESN, wherein the reading success probability information is 75%, 99%, 75%, and 60%, respectively.
In the embodiment, the type of the target vehicle identification code is determined through the vehicle bus protocol and the reading success probability, so that the vehicle-mounted terminal can be ensured to successfully read the vehicle identification code, and the condition that the vehicle identification code cannot be bound due to data loss caused by reading failure is avoided.
Further, in order to further avoid the situation that data is missing and cannot be bound due to reading failure, when the vehicle-mounted terminal reads based on the target identification code type, if the vehicle identification code type corresponding to the vehicle identification code which is not successfully read by the vehicle-mounted terminal occurs, the vehicle-mounted terminal can use a preset value as the vehicle identification code of the vehicle identification code type which is not successfully read by the vehicle-mounted terminal, and obtain at least two vehicle identification codes for the current vehicle according to at least one vehicle identification code which is successfully read by the vehicle-mounted terminal and the preset value. That is, if a vehicle identification code of a certain vehicle identification code type cannot be read by the vehicle-mounted terminal, the vehicle-mounted terminal may use a preset value as the corresponding vehicle identification code.
In order to better understand the method, an application example of the installation identification method of the vehicle-mounted terminal is described in detail with reference to fig. 3.
In order to provide accurate vehicle driving data for the vehicle networking platform, the vehicle-mounted terminal must be one vehicle-mounted terminal, that is, the vehicle-mounted terminal is not allowed to be changed and installed on other vehicles in midway; the application example can accurately bind the vehicle and the vehicle-mounted terminal, and guarantees uniqueness.
Because the vehicle brands are various, many vehicle types do not support the VIN code in the OBD bus output standard, the vehicle-mounted terminal cannot acquire the VIN of the vehicle through the OBD bus and cannot identify whether the current vehicle is a bound target vehicle or not, the VIN is public information, if only the VIN is used for binding, the risk of being counterfeited also exists, some personnel can simulate and counterfeit the data by means of simulation equipment, and the forged vehicle driving data is used as the driving data of the bound target vehicle and uploaded to the vehicle networking platform.
In order to realize the universality of binding between a vehicle and a vehicle-mounted terminal, increase the counterfeiting difficulty and solve the problem that the binding cannot be realized due to data reading failure, the application example adopts data of various vehicle information and performs fusion calculation to generate a fusion code for binding the vehicle and the vehicle-mounted terminal; after the vehicle-mounted terminal is changed and installed on other vehicles, the information acquired by the vehicle-mounted terminal from the vehicle can be synchronously changed, the generated fusion code can be correspondingly changed, and at the moment, the vehicle-mounted terminal can be accurately judged to be changed and installed on other vehicles, so that corresponding warning reminding can be carried out.
In the application example, the IMEI, the VIN, the SPID, the CALID, the CVN and the ESN are subjected to Hash operation, a Hash value is output, and the Hash value is used as a fusion code and is classified as a unique identity code bound by the vehicle and the vehicle-mounted terminal. The application example specifically comprises the following steps:
step 301, starting a current vehicle provided with a vehicle-mounted terminal;
step 302, the vehicle-mounted terminal judges whether a binding change request sent by the Internet of vehicles platform is received; if yes, go to step S314; if not, go to step S303;
step 303, the vehicle-mounted terminal identifies the vehicle bus protocol of the current vehicle through the bus technology, and if the vehicle bus protocol is identified to be the OBD protocol, the step S304 is executed;
step 304, the vehicle-mounted terminal reads the SPID through the OBD interface, and if the SPID cannot be read, a default value (equivalent to a preset value) is adopted;
step 305, the vehicle-mounted terminal reads the VIN through the OBD interface, and if the VIN cannot be read, a default value (equivalent to a preset value) is adopted;
step 306, the vehicle-mounted terminal reads the CALID through the OBD interface, and if the CALID cannot be read, a default value (equivalent to a preset value) is adopted;
step 307, the vehicle-mounted terminal reads the CVN through the OBD interface, and if the CVN cannot be read, a default value (equivalent to a preset value) is adopted;
step 308, the vehicle-mounted terminal reads the ESN through the OBD interface, and if the ESN cannot be read, a default value (equivalent to a preset value) is adopted;
309, the vehicle-mounted terminal performs hash operation on the IMEI, the VIN, the SPID, the CALID, the CVN and the ESN, outputs a hash value, and takes the hash value as a current fusion code;
step 310, the vehicle-mounted terminal judges whether a target fusion code is generated or stored before; if yes, go to step S313; if not, go to step S311;
step 311, the vehicle-mounted terminal stores the current fusion code as a target fusion code, and takes the current vehicle as a target vehicle;
step 312, the vehicle-mounted terminal takes the current fusion code as a bound target fusion code and reports the bound target fusion code to the vehicle networking platform through the network;
step 313, if the vehicle-mounted terminal generates or stores the target fusion code before, further judging whether the current fusion code is consistent with the target fusion code;
and step 314, if the current fusion code is inconsistent with the target fusion code, the vehicle-mounted terminal reports a binding change mark to the vehicle networking platform through the network so as to trigger the vehicle networking platform to confirm whether to change the binding to the user side (which is equivalent to confirm whether to change the vehicle-mounted terminal from the target vehicle to the current vehicle).
And if the vehicle networking platform receives the confirmed replacement information of the user side, sending a binding replacement request to the vehicle-mounted terminal, responding to the binding replacement request by the vehicle-mounted terminal, executing the step S315, and clearing the locally stored target fusion code.
According to the application example, a plurality of pieces of intrinsic information (VIN, SPID, CALID, CVN and ESN) of the vehicle and the intrinsic information (IMEI) of the vehicle-mounted terminal are fused, and a fused code is obtained through Hash operation, so that the problems that the vehicle terminal cannot read the VIN, data loss occurs, and recognition cannot be achieved and binding fails are solved.
It should be understood that, although the steps in the flowcharts of fig. 1 to 3 are shown in sequence as indicated by the arrows, the steps are not necessarily performed in sequence as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 1 to 3 may include multiple steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, and the order of performing the steps or stages is not necessarily sequential, but may be performed alternately or alternately with other steps or at least some of the other steps or stages.
