英文摘要: To solve the question that existing control theories and approaches of dynamics for Independent driven vehicles(IDV) do not match demands and development trends of networked control for dynamic torque distribution of independent driven systems(IDS), the proposer is projecting to research on issues and optimization approaches of networked control for dynamic torque distribution of IDS by integrating dynamics control models of IDV and in-vehicle network models,based on analysis and improving of existing strategies for dynamic torque distribution of IDS. This project is planned to consummate theories of discretization and networked for dynamics control models of IDV, based on previous research on dynamics control theories for the new dual-motor IDV, and also to do in-depth research on modeling theories and optimization approaches of networked control of dynamics for IDV. The research mainly includes: analysis and improving of existing theories and approaches of dynamic torque distribution of IDS, integrating of dynamics control models of IDV and in-vehicle network models, analysis of control performances for the integrated dynamics networked control models, optimization approaches of networked control of dynamics of IDV base on the algorithm of varying-sampling-rate intelligent scheduling and the theory of scheduli
