据不完全统计全球有70多家公司在开发“自动驾驶载人飞行器”，比如：英特尔与德国航空公司研发的Volocopter、空客（airbus）研发的CityAirbus、Uber开发的Uberair、Ehang自主研发的Ehang184/216等等，还有更多的公司正在研发其“载人飞行器”，如：日本电器公司（NEC）空中汽车，美国Lift Aircraft研发的Hexa，沃尔沃旗下飞行汽车创业公司Terrafugia开发的Transition，诺丁汉航空公司VRCO的飞行汽车叫做NeoxCraft ……
燃油动力系统和纯电动力系统哪个好？一直是广大车友讨论的话题；而更多的“自动驾驶载人飞行器”公司选择了纯电动力系统，以纯电动汽车为例，需要电力驱动系统、电源系统和辅助系统相互协调运行汽车；载人飞行器可能相对更加复杂，同时需要更大的动力源，因为拉升的消耗量远远高于平滑前进的消耗量。所以锂电池是飞行运转的根源，锂电池有着能量密度高，自放电小，可快送充放电，多环境下使用，使用寿命长的优势，也更为环保的优势，也是时代的“大势所趋”；电动汽车的锂电池已经有着多年的历史，样本采集和测试次数有了很大的保证，也会出现一定概率的电池问题；而载人飞行器公司有没有研发出适配飞行器的专业锂电池，有着多少次循环测试？但相信随着电池市场的增大和发展，这个问题是可以解决的。
所以“自动驾驶载人飞行器”安全吗？能上天么？讨论这些可能还相对的过早，因为这些还没有明确的投入商用，更多的只是在多环境下测试，和展会展示。低空载人飞行的确是一个人们向往的方向，但是任重道远，需要成千上万甚至更多次的测试和更多的数据进行支撑，来做到万无一失，我们期待未来可以坐上这样的“空中的士”也许这一天也并不遥远。

According to incomplete statistics, more than 70 companies around the world are developing “autopilot manned vehicles”, such as Volocopter developed by Intel and German Airlines, CityAirbus developed by Airbus, Uberair developed by Uber, and Ehang184 independently developed by Ehang. /216, etc., more companies are developing their "manned aircraft", such as: Japan Electric Corporation (NEC) aerial car, Hexa developed by Lift Aircraft of the United States, Transitionfu developed by Volvo's flying car startup Terrafugia, Nottingham The airline VRCO's flying car is called NeoxCraft...
Which is better for fuel-powered systems and pure electric power systems? It has always been the topic of discussion among the majority of riders; more "automated manned aircraft" companies have chosen pure electric power systems. For pure electric vehicles, for example, electric drive systems, power systems and auxiliary systems need to coordinate the operation of the car; Human aircraft may be relatively more complex and require a larger power source because the consumption of the lift is much higher than the smooth forward consumption. Therefore, lithium battery is the root of flight operation. Lithium battery has high energy density, small self-discharge, fast charge and discharge, multi-environment use, long service life and environmental protection. It is also the trend of the times. The lithium battery of electric vehicles has a long history, the number of sample collection and testing has been greatly guaranteed, and there will be a certain probability of battery problems; and whether the manned aircraft company has developed a professional lithium battery that adapts the aircraft. How many cycles have you tested? But I believe that with the increase and development of the battery market, this problem can be solved.
So is the "autopilot manned aircraft" safe? Can you go to heaven? It may be too early to discuss these, because these are not clearly commercialized, and more are only tested in multiple environments, and exhibitions. Low-altitude manned flight is indeed a direction that people are yearning for, but it has a long way to go and requires thousands or even more tests and more data to support it. To be foolproof, we look forward to sitting in the air in the future. "There may be no distant day."
