Abstract
As know, the autonomy level grows up, and the number of data exchanged between cars will be more.Several electronic parts have recently been added to automobiles, increasing the data and storage of cars.An internal network that communicates pertinent information status about the vehicle and is aware of a specific signal is built by the electronic components.The automobile has taken action to address this data and storage issue by making the CAN database (also known as a DBC format file), which contains the signal information assigned in the CAN data payload, secure.This paper demonstrates a method for gathering data from ECU, making it understandable to humans, and sending data or a wireless internet communication using an IOT platform.As a result, we suggest a solution: data must be compressed for quicker and more secure transmission.Data compression is performed before data transmission, it is used for reducing the number of bits used for each piece of data.Moreover, source encoding is necessary to restrict the size of data storage files.The three stages of this research are "CAN-bus data gathering, CAN data compression, and data transmission to cloud storage."By research, three objectives to identify the compression ratio, Graphical User Interface (GUI), and integration will be achieved.Unlike an existing method that is designed based on messages and signals with the Bit start, Bitlength, and CAN data payload in this study, we demonstrate that our method outperforms the current way of using a publicly accessible DBC format file named Open DBC as a reference.
