In step S230, according to the vehicle configuration information corresponding to each field, the CAN signal data of the vehicle to be collected is collected in a customized manner, and the CAN signal data of the vehicle to be collected is reported in a customized manner.
The method CAN receive the CAN signal acquisition template issued by the cloud of the Internet of vehicles, and each field contained in the CAN signal acquisition template is customized according to the CAN signal data, so that vehicle configuration information corresponding to each field is determined, the CAN signal data is customized to acquire the vehicle configuration information including the identification of the vehicle to be acquired, the CAN signal data of the vehicle to be acquired, the acquisition frequency of the vehicle to be acquired and the reporting frequency of the vehicle to be acquired, and the CAN signal data of the vehicle to be acquired is acquired according to the vehicle configuration information corresponding to each field, so that the CAN signal data CAN be acquired through the customized CAN signal acquisition template, and the CAN signal data is acquired in a flexible and targeted manner, thereby facilitating the analysis of the CAN signal data by the cloud of the following Internet of vehicles.
In some embodiments, the CAN signal acquisition template may be generated by the internet of vehicles cloud according to vehicle data generated by a vehicle-related scene. For example, for historical CAN signal data generated in different scenes of various vehicle types, various corresponding CAN signal acquisition templates are configured, and in this way, the CAN signal acquisition templates CAN be dynamically configured according to actual requirements.
In some embodiments, the above-mentioned CAN signal data of the vehicle to be collected includes any one or more of: vehicle battery data, vehicle chassis data, vehicle dynamics data, and user driving behavior data.
Based on the foregoing embodiment, the CAN signal acquisition template may be an acquisition template configured based on any one or more of the above-described vehicle battery data, vehicle chassis data, vehicle power data, and user driving behavior data.

Based on the foregoing embodiment, in order to ensure that the customized acquisition version of the vehicle end is up to date, the vehicle end needs to report its corresponding acquisition version in real time when being powered on each time, and the corresponding reporting protocol is as follows:
examples are as follows:
{
"msgHdr":{
"deviceID":"1234567890",
"timestamp":1547013623000,
"transID":"123456789012345678"
},
"data":{
"canCfgVer":2
}
}
in the above example, canCfgVer represents version information of a CAN signal acquisition template of a vehicle to be acquired.
Based on the foregoing embodiment, when the cloud end of the internet of vehicles receives the version information of the CAN signal acquisition template, namely, 2, the version information of the CAN signal acquisition template stored in the cloud end of the internet of vehicles is acquired according to the identification of the vehicle to be acquired, and is compared with the received version information, so as to check whether the version information of the acquisition template at the vehicle end is the latest version information.
