Development of data acquisition system and data analysis technique for automotive applications

This paper proposes the design, analysis and processing methodologies for the data generated by the custom designed data logger for quick deployment. The primary goal is to develop a prototype system for automobiles which can reduce the `Acquisition to Analysis' time for the generated data. The proposed data acquisition (DAQ) system is rugged and modular. Since most existing DAQ systems fail for automotive use due to their application-specific nature and lack of data filtering and processing capabilities. The system so developed, log data at a baud rate of 9600 bps and employ 10-bit resolution for the representation of analog data from the sensor. This coupled with data logging using SD card shield V3.0 and data analysis on MATLAB graphical user interface helps to reduce the testing and prototyping time of vehicle under test.
