14. Expressions

博客介绍表达式是运算符和操作数的序列,定义了表达式的语法、操作数和运算符的求值顺序,以及表达式的含义。
An expression is a sequence of operators and operands. This chapter defines
the syntax, order of evaluation
of operands and operators, and meaning of expressions.
内容概要:本文围绕新一代传感器产品在汽车电子电气架构中的关键作用展开分析,重点探讨了智能汽车向高阶智能化演进背景下,传统传感器无法满足感知需求的问题。文章系统阐述了自动驾驶、智能座舱、电动化与网联化三大趋势对传感器技术提出的更高要求,并深入剖析了激光雷达、4D毫米波雷达和3D-ToF摄像头三类核心新型传感器的技术原理、性能优势与现存短板。激光雷达凭借高精度三维点云成为高阶智驾的“眼睛”,4D毫米波雷达通过增加高度维度提升环境感知能力,3D-ToF摄像头则在智能座舱中实现人体姿态识别与交互功能。文章还指出传感器正从单一数据采集向智能决策升级,强调车规级可靠性、多模态融合与成本控制是未来发展方向。; 适合人群:从事汽车电子、智能驾驶、传感器研发等相关领域的工程师和技术管理人员,具备一定专业背景的研发人员;; 使用场景及目标:①理解新一代传感器在智能汽车系统中的定位与技术差异;②掌握激光雷达、4D毫米波雷达、3D-ToF摄像头的核心参数、应用场景及选型依据;③为智能驾驶感知层设计、多传感器融合方案提供理论支持与技术参考; 阅读建议:建议结合实际项目需求对比各类传感器性能指标,关注其在复杂工况下的鲁棒性表现,并重视传感器与整车系统的集成适配问题,同时跟踪芯片化、固态化等技术演进趋势。
