Tesla通过分析真实车队碰撞数据,结合视觉系统与传感器,实现了安全系统的突破。传统碰撞传感器需要时间确认,降低阈值可能导致误触发。而视觉系统能提前“看到”即将发生的碰撞,与传感器协同,使约束控制器能更早、更准确地启动安全气囊和安全带预紧器。通过仿真重放碰撞并测量人体模型受力,团队发现提前部署能优化保护时机。这一改进使预测伤害严重程度整体显著下移,并通过OTA更新实现,是前所未有的安全提升。

Every one of these dots is an actual crash from the fleet. Real world speeds, collisions, and people. Not just the regulatory test cases. The richness of this data is what enabled the result. With simulation we can replay the crashes and measure the forces on the human body model. Then sweep through restraint deployment times to find that deploying earlier gives the time for the bag to be inflated optimally and seat belt pretension before the occupant has moved out of position. But it takes time for crash accelerometers to be certain. Lowering that time threshold risks unwanted deployments. Using vision gives the vehicle confidence to reduce that timing. The camera sees the impending impact and together with the sensors tell the restraint controller to reduce the filter and act sooner. The Y Axis shift in Predicted Injury Severity is based on sensors in the human body models from rerunning the crash simulations with the faster detection threshold. Such a reduction in injury severity across the spectrum is unheard of, let alone doing this via an update over the air. I'm extremely proud of the analysis team's work and dedication. Going above and beyond to ask "we have the safest car on the road but can we make it even safer?" And then working with the vision team to build the predictions needed to make it happen. Rigorously tested in simulation and then in physical crash testing. Now deployed and improving lives. I watch the video on loop and just imagine each dot, a person.在 X 查看被引用的帖子
