Abstract

The invention discloses a data acquisition method and device, a storage medium and a processor. The method comprises the steps of determining a to-be-collected variable of a target vehicle based on atransmission protocol of a target platform; obtaining a variable acquisition parameter corresponding to the to-be-acquired variable from a DBC file received by the target platform; determining a flashing file according to the variable acquisition parameter corresponding to the to-be-acquired variable and variable storage address information in a vehicle-mounted network connection terminal; and inthe vehicle-mounted network connection terminal, obtaining a variable value corresponding to the to-be-acquired variable based on the flashing file. The problem that the fixed variable value in the DBC file can only be acquired by the vehicle-mounted network connection terminal by changing an application program when the version of the whole vehicle protocol for transmitting the DBC file is updated in the prior art is solved.

Description

technical field

[0001] The present application relates to the technical field of motor vehicle control, in particular, to a data acquisition method, device, storage medium and processor. Background technique

[0002] According to regulations, OEMs need to transfer the vehicle information to the corresponding platform according to the standard data transmission protocol and the determined variable data to achieve this, but the vehicle agreement of different models will change accordingly, and there are still The status of vehicle agreement version update.

[0003] The data collection method in the related art can only perform data collection configuration based on an uncertain data transmission format. Specifically, the variables to be collected are transmitted to the platform according to the format of the configuration table. At present, for fixed variable data collection, the vehicle protocol version is updated, and the firmware of the data collection terminal of the vehi...
