Design and Implementation of Vehicle Data real-time Acquisition System

Different drivers produce different characteristics of driving data, for different requirements of the vehicle reliability, safety and comfort, the driving style is analyzed according to the driving data collected by the vehicle. This paper presents and designs a platform of vehicle operation data real-time acquisition based on UDS diagnosis. The platform uses MCU and CAN controller to build communication modules, and with PC to control data collection, display and preservation. The overall design process is systematically elaborated in this paper, including the design method of vehicle embedded data acquisition terminal and PC monitoring terminal, focusing on the design of platform communication protocol. The test results show that the platform satisfies general vehicle data acquisition requirements.
