Abstract

The invention relates to an intelligent networked automobile system cooperative control method based on TPZN, which belongs to the field of unmanned driving, prediction and control strategies, and realizes functions by fusing Z language formal description and a TPN model into a new TPZN model, and can effectively solve the problems of state explosion caused by numerous node devices of a time Petrinetwork and insufficient dynamic capability and real-time performance of a Z frame. The established TPZN formal model for intelligent networked automobile system cooperative control can realize cooperative control of intelligent networked automobile system information security transmission in a multi-source heterogeneous complex environment. And the driving safety and reliability of the intelligent networked automobile are improved.

Description

technical field [0001] The invention relates to a TPZN-based intelligent networked vehicle system collaborative control method, which belongs to the field of unmanned driving, prediction and control strategies, and is especially suitable for intelligent networked vehicle system collaborative control. Background technique [0002] With the maturity of artificial intelligence, big data analysis and processing technology, wireless communication technology, Internet of Vehicles, and unmanned driving technology, intelligent networked vehicles have been widely used in civilian and military fields such as logistics, people's lives, and military deployment. In this multi-source heterogeneous and complex environment, the collaborative control of intelligent networked vehicle systems is particularly important. The use of formal modeling and analysis methods with strict mathematical logic foundations to predict the cooperative control strategy of intelligent networked vehicle systems i...
