Analysis Of Control Stability Of The Super Micro-electric Vehicle Based On Human-machine Behavior Coupling Dynamics

Because of extremely lightweight and miniaturization of the micro-electric vehicl,there would be some new theories and technologies to be researched on its safety aspect.Based on the National Nature Science Fund-Research on Modeling Method andBehavior Coupling of Human-Machine Dynamics for Small Scale Electric Vehicle, thesimulation analysis of the vehicle control stability of the micro-vehicle under thebehavior coupling of Human-Machine dynamics has been made.The main content of this paper is as follows:First, a model of micro-electric vehicle has been made in ADAMS according totwo types of existing electric vehicle. There is on such an existing vehicle similar to, oreven close to micro-electric vehicle mentioned before in mass and scale, because themicro-electric vehicle is still on concept stage. So, a micro-electric vehicle with themass less than300kg has been developed according to the need of the research.Then, twelve DOF human-seat mathematical and realistic (in ADAMS) model hasbeen made based on nine DOF human-seat model built by Professor Younggun Cho, Yong-San Yoon, and added the realistic one into the micro-electric vehicle built before inADAMS. Human body is regarded as a passive multi-body interacted with seat and thevehicle through plastic contacts, when researching on human-machine dynamiccoupling effects. The existing human-seat models are mainly aimed at the ride comfortof the vehicle, so the research methods and procedures of these model is different fromwhat we need in human-machine dynamic coupling effects research。 So, the twelveDOF human-seat model has been made according to the characteristic of the human-seat dynamic coupling effects research.Third, stability control simulation of micro-electric vehicle has been made, and abrief judgment has been made according to the simulation results. The control stabilityof the micro-electric vehicle is the basis and the foundation of the human-machinedynamic coupling effect analysis. If it can’t meet the control stability standards becauseof its unreasonable design, the accuracy of the simulations made afterwards based on itwill also be doubtful. So, simulation and judgment of control stability of the micro-electric vehicle has been made, and the results revealed that the control stability of themicro-electric vehicle meet the national standards, and the design of the micro-electricvehicle is reasonable. Finally, the control stability of micro-electric vehicle under human-machinedynamic coupling condition has been made, and comparison between with and withouthuman-machine dynamic coupling conditions has been made. From the comparison, wecan draw the conclusion that the control stability of micro-electric vehicle under human-machine dynamic coupling condition has apparent distinct with control stability ofmicro-electric vehicle without human-machine dynamic coupling condition.The simulation and analysis made in this paper, is one aspect of human-machinedynamic coupling interactive effects. The micro-electric vehicle model developed in thispaper demonstrated a new direction of the design of micro-electric vehicle. The human-seat model built in this paper offered a brand new idea to the research of human-seatinteraction, and possessed important reference values.
