This paper proposed a vehicle monitoring system for low-emission zone application based on OBD (on-board diagnostics) technology. The proposed system is composed of OBD, GPS, 4G mobile communication, and Internet cloud computing technologies. The proposed system could implement in real time the function of vehicle status surveillance and could be applied to low-emission zone (LEZ) application. The monitored features cover vehicle identification number (VIN), malfunction indicator lamp (MIL) status, and number of diagnostic trouble codes (DTCs). These vehicle information, i.e., VIN, MIL, and DTC, as well as GPS data will be sent to the Internet cloud computing server using 4G mobile network for LEZ application. Once the system discovers the vehicle does not meet the LEZ standards and drives into LEZ, the proposed system could inform the user and management department to deal with this violation situation. The system presented in this paper provides a new way to control the LEZ and has high potential for the applications of vehicle monitoring management. |
