现有的自动泊车辅助系统标准缺乏全面客观的测试场景。本文从现有的标准出发，基于中国自然驾驶数据分析了泊车过程中驾驶人的泊车行为特性，提取出了典型车位的类型、尺寸及泊车过程的车速数据。从泊车位搜索、泊车能力以及安全体验三个方面设计了包括平行泊车、垂直泊车在内的自动泊车辅助系统测试场景及其相关的参数。本文设计的测试场景可用于自动泊车辅助系统的测试评价。
自动导向车(Automated Guided Vehicle,AGV)采用非接触供电技术(Contactless Power Supply,CPS)可以实现电能的无接触且持续性传输,能克服传统蓄电池供电模式带来的在线工作时间限制、环境污染等种种弊端。本文通过对非接触电缆的周围磁场分布的研究,详细分析不同方向的磁场分量与检测位置坐标的变化关系,实现对AGV的位置偏差和角度偏差的多点监测,同时电子芯片
针对全新开发全浮式商用车悬置系统，利用多软件交互式建模手段，建立驾驶室悬置虚拟样机ADAMS分析模型。实现驾驶室运动干涉检查、悬置机构原理分析、翻转特性分析、关键部件受力分析及开发风险识别。通过相应的对比试验，验证仿真模型的精度及可靠性。该套仿真分析方法可作为驾驶室悬置系统前期开发过程的必要辅助手段。
