“特斯拉刹车失灵”事件的车辆运动模型与分析

DYNAMIC SIMULATION AND ANALYSIS OF “BRAKE FAILURE” OF TESLA ELECTRIC VEHICLE

  • 摘要: “特斯拉刹车失灵”事件引起社会热议,本文根据现代车辆的阿克曼转向原理,利用车辆运动方程构建了模型,结合特斯拉公布的数据还原了事故发生前的行车状态和轨迹。结果与车主张女士对事故的定性描述一致,由此判断特斯拉提供的数据基本可信。在此基础上,本文还对网友和车主提出的三方面质疑进行了讨论,本文认为事发时车辆制动系统是正常工作的,车辆存在超速行驶的可能。

     

    Abstract: The event of “Tesla brake failure” has sparked heated discussions in the society. In this paper, based on Ackerman steering technology and vehicle motion equations, a model is built to restore the driving state and the track before the accident according to Tesla's published data. The result is consistent with the qualitative description of the accident given by the owner. So, it can be judged that the data provided by Tesla is basically credible. This paper also discusses the three questions raised by netizens and car owners. It is proved that the braking system works normally and the possibility of overspeed driving exists.
