Multi-information fusion test system and method for electric vehicle test evaluation

Abstract

The invention provides a multi-information fusion test system and a method for the test evaluation of an electric vehicle. According to the technical scheme of the invention, the data receiving terminal of a multi-information fusion data acquisition host is connected with the data sending terminal of an analog quantity module. The data acquisition terminal of the analog quantity module is connected with the data sending terminal of a power analyzer through a CAN bus. The data receiving terminal of the power analyzer is connected with a power CAN bus. The power CAN bus is connected with a vehicle-mounted power system. The data sending terminal of the CAN bus of a vehicle diagnostic instrument is connected with the diagnostic data terminal of the multi-information fusion data acquisition host. The data receiving terminal of a frequency quantity module is connected with a vehicle-mounted frequency data sending terminal. The data sending terminal of the frequency quantity module is connected with the data receiving terminal of a thermocouple module. The data sending terminal of the thermocouple module is connected with the data receiving terminal of the multi-information fusion data acquisition host. In this way, the checking availability of original data is guaranteed. Meanwhile, the synchronism of all acquired signals and the consistency of sampling frequencies can be ensured.

Description

technical field [0001] The invention relates to the field of electronic circuit control, in particular to a multi-information fusion testing system and method for testing and evaluating electric vehicles. Background technique [0002] At present, many automobile companies at home and abroad have developed some pure electric drive electric vehicles one after another. However, there are still large gaps in terms of power, economy, and safety. How to effectively test and evaluate the domestic and foreign pure electric drive vehicles that have been developed, how to quickly learn foreign advanced design concepts of low energy consumption and high safety pure electric drive vehicles, master these key technologies, and conduct experimental research and comparison of advanced prototype vehicles at home and abroad Analysis is an important means to understand and master the core technology of pure electric drive electric vehicles. [0003] In response to these requirements and purp...

Problems solved by technology

[0003] In response to these requirements and purposes, vehicle manufacturers and research institutions at home and abroad use the data acquisition system commonly used in the market to evaluate the performance of new energy electric vehicles for specific vehicle performance or a key component. However, with the testing and evaluation Due to the diversification and complexity of the content, the above-mentioned data acquisition system cannot complete the tasks of testing and evaluating multiple research objects and multiple physical quantities under the same working condition. The synchronization of the collected signals of each device and the consistency of the sampling frequency of the collected signals of each device, the above problems bring great difficulties to the later data processing analysis and final performance evaluation
