Abstract:  Vehicle dynamics and its control-by-wire technologies are difficult problems in the design of vehicle chassis, which has been an academic research hotspot. The development of intelligent vehicle also puts forward better performance and more urgent requirements for the control-by-wire execution technologies of chassis. This paper introduces the latest development of vehicle dynamics and chassis control-by-wire technologies: In aspect of vehicle dynamics and control technology, introduces the development and research status of vehicle dynamics modeling analysis, dynamics state observation and dynamics stability control strategy; In aspect of the control-by-wire execution technologies of chassis, summarizes the development and research status of braking-by-wire, steering-by-wire and driving-by-wire for autonomous driving. In aspect of the integrated control technologies of vehicle chassis, a concept of chassis dynamics domain control is proposed, and a domain control architecture and coordinated control strategies are introduced systematically. At last, the future research trends of the chassis control-by-wire technologies and dynamic domain technologies are prospected.

Key words: vehicle dynamics, intelligent vehicle, control-by-wire of chassis, dynamics domain control; integrated and coordinated control
