Power matching of flying cars during takeoff stage based on dual-mode driving

To solve power-matching problem during takeoff stage of folding wing flying car, the basic dynamic control strategy was studied. The dual-mode driving characteristics during takeoff stage were analyzed through theoretical calculation, and the concept of the optimal switching time was proposed. Based on the basic parameters and results of power-matching calculation of the concept car, the driving state simulation models under different working conditions were established in Simulink. According to the driving state simulation mo-dels, the simulation analyses on driving state during takeoff stage were conducted, and the dual-mode driver selection principle and optimum matching scheme of switching time were obtained. The calculation results show that the takeoff acceleration time is reduced by 22% and the takeoff distance is shortened by 13% based on dual-mode driving. The optimization analyses on transmission and vehicle parameters and variation of output characteristics were further conducted, from which the effect of the parameters on power performance during takeoff stage was obtained.
