Flying Car Rollover Stability Study When Driving On Land

The emergence of the flying car is an important breakthrough in the development of theworld auto industry, which will bring much convenience to people’s life. In order to meet theflight stability, the flying car has a high center of gravity height. It is prone to rollover whenthe car driving on land, and the casualties and property loss which rollover accident causedwas extremely serious. So when the cars are driven on the land, it is particularly important toensure the safety of the new car driving.Based on ordinary cars and rotor as the rotation of the folding type rotorcraft flying caras the research object, this paper established three degree of freedom model, which caninfluence lateral, lateral, and yaw motion. Considering the flight vehicle making uniformcircular along in the process of steady state response, this paper indicates that the structurefactors affecting a cartwheel dynamic stability and control parameters, by the way of theanalysis of the equilibrium condition of flight vehicle side tumbling stability,.The location of the center of gravity is one of the important factors influencing the flyingcar ground side tumbling stability, but also the important factors influencing the flying car airflight stability, in order to meet the flight stability as a precondition, constraint conditions aregiven in the paper and the longitudinal position of the center of gravity height. After that, theposition of the center of gravity of the limit not only ensures the stability of the flight vehicleflying in the air, also ensures the flight vehicle road not by the center front and tailphenomenon or focus on the after effects of rollover stability.This paper use CarMaker software to simulate the flight car in Double-Lane Changecondition and Fish-Hook condition. The flying car dynamics simulation was carried out underthe special condition, analyzed the influence of the important evaluation indexes, draw aconclusion that can take the initiative control, steering Angle and lateral load controlstrategies to prevent the occurrence of side rolling, when the flying car driving under specialconditions. After the emergency, the driver and the time delay of the actuator, rolloverwarning system must have enough warning time. According to the change of the values oflateral load transfer rate LTR warning conditions to trigger the rollover control system, andanalyzed the algorithm of the warning time. The warning system began to warn the driver andto trigger the controller to work. Based on the coupling, yawing and roll movement, proposes differential braking rollover prevention control strategy, by controlling each wheel brakingdeceleration and yawing moment resistance, it is effect to reduce the lateral acceleration of theflying car.
