CAN Sniffing for Vehicle Condition, Driver Behavior Analysis and Data Logging

There are many Electronic Control Units (ECU) and sensors in a vehicle. The sensor information is sent via the Control Area Network (CAN) of a vehicle. Crucial data base by the CAN. This data may not be important to the driver, but if the CAN messages are analysed, then vehicle parameters and vehicle conditions can be determined. This data can determine ahead of time any possible future failure and the driver can be alerted about it. This paper presents standalone embedded system that could do the aforementioned task were valuable lives may be saved. The proposed hardware system acquires CAN data from a vehicle (CAN sniffing). The data is then processed and appropriate message is then displayed to the driver. The proposed system also stores the CAN messages on to an industrial grade SD card (CAN logging) for future analysis. The proposed system also perform driver behaviour and driving terrain analysis.
