伴随着智能化汽车的迅猛发展，“ 软件定义汽车 ” 的观念日益深入人心。在这一理念的框架之下，唯有实现软件的快速迭代更新，才能确保车辆的竞争力。然而，在日趋频繁的 OTA 升级活动中，过长的OTA升级时间抑制了用户触发升级的意愿。因此，如何缩短用户的有感升级时间，成为提升用户体验的关键所在。基于此，文章提出一种基于 FA 协同调度的 OTA 并行升级方法，将原本串行的升级方式优化为并行升级。通过实车试验验证，本文所提出的方法能够显著缩短升级时间。

With the rapid development of intelligent vehicles, the concept of "software-defined vehicles" has increasingly taken root in people's hearts. Under the framework of this concept, only by achieving rapid iterative updates of software can the competitiveness of vehicles be ensured. However, in the increasingly frequent OTA upgrade activities,the overly long OTA upgrade time has suppressed users' willingness to trigger upgrades. Therefore, how to shorten the perceptible upgrade time for users has become the key to enhancing user experience. Based on this, the article proposes an OTA parallel upgrade method based on FA collaborative scheduling, optimizing the original serial upgrade mode to a parallel upgrade. Verified through real vehicle tests, the method proposed in this paper can significantly shorten the upgrade time.
