Detailed Description
The invention is described in further detail below with reference to the accompanying drawings.
The embodiment of the method for detecting the communication link of the vehicle part comprises the following steps:
the method for detecting the communication link of the vehicle parts shown in fig. 1 comprises the steps that firstly, a network connection terminal of a vehicle is utilized to obtain a configuration file of the vehicle, which is issued by an OTA platform, the network connection terminal collects vehicle OTA part information according to the obtained configuration file, the collected OTA part information is sent to the OTA platform, the OTA platform compares the received OTA part information sent by the network connection terminal, and whether the communication link is normal or not is determined according to a comparison result through the OTA part information corresponding to the stored vehicle configuration information of the OTA platform, so that the detection of the communication link of the vehicle parts is completed. The specific implementation mode is as follows:
in this embodiment, the components of the vehicle need to develop the OTA function, and the network terminal of the vehicle needs to have the OTA capability, so that the communication link detection of the components of the vehicle cannot be performed by using the method for the vehicle without the OTA capability.
1. The vehicle network terminal is used for acquiring a configuration file of the vehicle issued by the OTA platform, acquiring vehicle OTA part information (comprising a part physical request ID, a response ID, a network type, a PIN value, a function request ID and a node original address) according to the acquired configuration file, and uploading the acquired OTA part information to the OTA platform.
Specifically, the OTA platform, that is, a platform for managing the upgrade vehicle, the parts and the software information, can implement remote upgrade of the specified vehicle by configuring the upgrade vehicle information, the part information and the software package information. In this embodiment, after receiving registration information after the vehicle internet connection terminal is activated by VIN information registration, the OTA platform issues a configuration file of the vehicle to the vehicle internet connection terminal.
The vehicle information is required to be added on an OTA platform before leaving the factory, wherein the vehicle information comprises information such as a vehicle type code, a vehicle type description, a sales order number, VIN, a vehicle work number, a part hardware material number, a software package type identifier, a part physical request ID, a response ID, a network type, a PIN value, a function request ID, a node original address, an upgrade mode and the like. The OTA platform can determine a specific vehicle for detecting a communication link and how many OTA parts can be detected through vehicle type coding, vehicle type description, sales order number information and VIN information, and after the vehicle is determined, the position, the current version and whether the updating is carried out on each OTA part of the vehicle can be determined through the information of part physical request ID, response ID, network type, PIN value, function request ID, node original address, updating mode and the like. When the OTA platform issues an instruction to the networking terminal, the instruction needs to be sent to the V+ platform and then to the networking terminal through the V+ platform. For the response of the OTA platform, when the OTA platform responds to the request of the internet connection terminal, the response file may be directly sent to the internet connection terminal, for example, in this embodiment, the OTA platform may directly send the generated configuration file to the internet connection terminal.
Therefore, before the vehicle is registered on the OTA platform, workshop staff needs to register the network connection terminal information of the vehicle to a V+ platform (a vehicle management platform, namely, the vehicle management platform is used for realizing the acquisition, storage and transmission of all working conditions of the vehicle and static and dynamic information of the vehicle), when the network connection terminal is electrified for the first time, the vehicle is linked to the V+ platform for activation according to an initialization program, and the V+ platform manually inputs VIN information of the vehicle by using the acquired vehicle registration information and transmits the VIN information to the network connection terminal of the vehicle. The VIN information of the internet-connected terminal of each vehicle is uniquely determined when in use, but the VIN information of the internet-connected terminal is not permanently fixed, and when the internet-connected terminal of the vehicle is damaged and maintained, the VIN information of the internet-connected terminal is replaced by other unused VIN information. And the network connection terminal registers and activates in the OTA platform according to the acquired VIN information. The VIN information of the vehicle comprises vehicle information which can be identified by a vehicle manufacturer, a vehicle production date, a vehicle type and the like.
The OTA platform receives registration information of the vehicle, after the network connection terminal is activated, the OTA platform transmits an instruction for detecting the part communication link to the network connection terminal through the V+ platform, the network connection terminal responds to the instruction after receiving the instruction, a request for detecting the part communication link is sent to the OTA platform, and the OTA platform transmits a configuration file for the vehicle after receiving the request. The content of the configuration file comprises vehicle information, part physical request ID, response ID, network type, PIN value, function request ID and node original address.
And when the network connection terminal is electrified, automatically acquiring a configuration file issued by the OTA platform, searching the configuration file according to the attribute information of the parts in the configuration file, collecting the corresponding part information of the vehicle, classifying and summarizing the collected information, and then uploading the classified and summarized information to the OTA platform.
And 2, the OTA platform compares the received OTA component information uploaded by the network connection terminal with OTA component information corresponding to the stored vehicle configuration information of the OTA platform, and determines whether the communication link is normal according to a comparison result.
After the OTA platform receives the component information (the component hardware material number, the component physical request ID, the software type identifier and other information) acquired by the network connection terminal, the component information is compared according to the corresponding information stored in the platform, when the component information comparison results are consistent, the OTA component communication link of the vehicle is normal, otherwise, the OTA component communication link of the vehicle is abnormal, and the post maintenance of the component is required. When the communication links of the parts are normal, the whole vehicle can be successfully upgraded. The OTA platform displays the information of the parts collected by each vehicle, such as a physical request ID, a response ID and the like, in the report module, and displays the comparison result of the input information and the collected information of the platform.
According to the above process, the network connection terminal collects OTA part information according to the configuration file of the OTA platform and uploads the OTA part information to the OTA platform, the OTA platform compares the received OTA part information with the vehicle configuration information stored by the OTA platform, and whether the OTA part of the vehicle is normal is determined according to the comparison result. By the method, when the vehicle has an upgrading requirement, the situation of upgrading failure caused by the fact that a link is not enabled can be avoided, and the success rate of vehicle upgrading is improved. Meanwhile, the method can finish the communication link detection of the OTA parts of the vehicle only through the OTA platform and the network terminal, multiple upper computers are not needed, the technical threshold of vehicle communication link detection is reduced, and the detection efficiency is improved.
