Design of Object-Oriented Failure Detection Expert System of Autonomous Vehicle

In order to improve accuracy and diagnosis efficiency of automotive power supply failure detection expert system of existing autonomous vehicle, a modified depth-first search algorithm is used to design inference machine. In order to address the difficulty of the static tree model in applying to complicated vehicle power supply system, dynamic tree generation algorithm is designed. Object-oriented programming approach is utilized to design power supply failure detection expert system of autonomous vehicle, for fault reasoning and positioning, the expert system is then simulated and tested on vehicle. Test results show that this expert system can accurately and rapidly infer fault cause and locate fault position.
