In this paper, we research and implement an advanced autonomous vehicle security system. The two cores of GSM and GPS are implemented to realize the system. By combining GSM and GPS, we wish that system could inform the owner of where the vehicle is and what the states of car are in real time when the system is fired. In the process of design, we accomplish first the circuits of master system and rim. Then we let the signal of each rim circuit be accepted by microprocessor. The major system is connected to the GSM network. After the GSM network is connected, the security system starts to function according to the system mode and the parameters that are set by user. The simulation results show that the system works accurately and has a good performance.
