轮毂/轮边电驱动汽车底盘系统构型与集成优化设计及综合动力学协调控制

The technology developments and theory studies of electrified chassis system equipped with in-wheel or close-to-wheel motors, have been technology focus of automotive industry and hot spot of academic world. .This project aims at structural optimization and cooperative control of electrified chassis system with distributed driven motors, from the viewpoints of topological architecture, system analysis and design of in-wheel and close-to-wheel motors, and coordinated motion control of vehicle..Firstly, this project will establish systemic architecture design and parameters matching methods, based on an innovative considerations on hybrid driving, hybrid braking and differential steering functionalities. Secondly, this project will master the key optimum technologies of in-wheel-motor system by taking into account the coupled thermo-mechanical effects and torque-excitation effects between electromagnetic machine and frictional brake ,and the core design technologies close-to-wheel system by considering the coupled kinematic and dynamic of close-to-wheel machine and suspension system. Finally, this project will establish coordinated motion control method to improve the maneuverability, stability and comfortability, and the intelligent fault diagnosis and fault tolerant control methods to enhance the reliability, taking advantages of multi-actuators and multi-sensors.
