   The current stage of autonomous driving calls for drivers to remain actively engaged within the control loop in anticipation of the need for takeover operations. However, regaining control of the vehicle from a state of low situation awareness (SA) poses a challenge. To address this issue, this research introduces a novel takeover method based on haptic shared control, ensuring a smooth and safe takeover process. A symmetric softmax function is formulated to evaluate muscle state, taking into account the varying torque thresholds associated with different vehicle speeds, as well as utilizing the driver’s cognitive state to characterize their SA. Within the takeover process, a coordinator leverages the driver’s SA and human-machine intention similarity to determine the current state of human-machine collaboration. Subsequently, different control allocation strategies are then adopted for different states, and the driver is guided through force feedback. Experiment results demonstrate the effectiveness of the proposed method, showcasing its ability to facilitate a smooth and safe transfer of control, regardless of the presence of conflicts or the harmonious state existing between the human driver and the automated system.

   主板功能测试旨在拦截不良主板流入笔记本电脑整机组装产线，避免增加返修成本。现有产线通常采用“必测项全检 + 选测项按比例抽检”的测试策略， 存在漏检风险高、测试效率低的不足。对主板功能测试策略进行优化，不仅有助于降低不良主板的漏检率，还能有效提高测试效率，从而降低返修和测试成本。 现有的测试策略优化方法依据历史良率进行设计，在产线良率波动时因响应滞后无法及时进行测试策略调整，导致在良率下降时因测试不足增大漏检风 险，在良率提升时因过度测试影响测试效率。 针对现有方法的局限性，本文提出了基于良率预测和异常检测的主板功能测试策略优化方法。与现有优化方法相比，可以有效应对良率波动的场景，降低由返修和测试成本组成的总成本
