Problems solved by technology
[0003] The problem existing in the existing technology is that in various technical solutions, the information exchanged by each control unit has a large degree of reusability, but in different projects and at different development stages, where these CAN information is located The messages and message attributes are very different
Therefore, when using CAN tools for power system analysis and testing, once the CAN communication database is changed, the test configuration file needs to be redesigned, which is time-consuming and error-prone, which brings great inconvenience to the analysis and testing personnel

The invention provides a testing device and method used for a power system of a new energy automobile. The testing device comprises a CAN database, an input module, a functional processing module, an output module and a human-computer interaction interface, wherein the CAN database is used for analyzing signals on a CAN bus according to a preset CAN communication protocol to acquire performance data of the power system, the input module is used for assigning the performance data to corresponding variables, the functional processing module is used for processing the variables to acquire the performance data and analyze the performance of the power system and outputting corresponding signals according to analysis results; the output module is used for mapping the output signals to display driving signals, and the human-computer interaction interface is used for displaying the analysis results according to the display driving signals. According to the testing device and method used for the power system of the new energy automobile, the CAN database is only correlated to the input module, the output module is used for keeping the independency between the functional processing module and the human-computer interaction interface, therefore, when project change happens, an original testing device can be used for establishing a testing environment fast only by modifying the input module, and working efficiency is improved.
Description
Technical field [0001] The present invention relates to the technical field of automobile manufacturing, in particular to a test device and method for a power system of a new energy automobile. Background technique [0002] At present, new energy vehicles generally use CAN (Controller Area Network, Controller Area Network) bus to build the communication within the power system and between the power system and the various subsystems of the prototype car. As a result, CAN tools can be used to test and analyze the CAN bus, and signals on the CAN bus can be used to analyze system functions. When using CAN tools for test analysis, a test configuration file is required. [0003] The problem with the prior art is that in various technical solutions, the information exchanged by each control unit has a large degree of reusability. However, in different projects and in different development stages, where the CAN information is The messages and message attributes are very different. There...
