【摘要】：随着汽车工业的迅猛发展，汽车电子已经成为汽车产品的核心竞争力之一。从最早的车灯、电动雨刷，到现在的ABS（刹车防抱死系统）、PKE（被动无线钥匙）、自动泊车系统、ESP（车身稳定系统）、防夹车窗、按摩座椅等，汽车电子产品已经不仅满足乘车者的基本需求，而是向着安全、舒适、个性的方向发展。各个厂商也纷纷将汽车电子产品作为产品定位的最主要依据之一。可以说，在物理化学领域没有重大发展之前，汽车电子的发展决定了汽车的未来。汽车车身电子是目前汽车电子行业发展比较成熟的一个领域，也是目前消费者感受最直观的汽车电子系统。汽车电子产品不仅工作环境非常恶劣、工况复杂，还要面对很多人为失误的破坏，使得产品对于可靠性和错误保护的要求很高。因此汽车行业建立了众多技术标准，以保证汽车的安全性和可靠性。针对这些标准的电路需要硬件工程师用丰富的经验和大量的时间，经过大量的试验来设计，其设计成本居高不下。另外汽车产品的元器件都必须经过汽车级认证，通过一系列苛刻的试验，建立完善的科研和生产管理流程。再加上汽车功能的独特性，使得很多芯片厂商为汽车电子设计了品种丰富的芯片以供选择。因此汽车电子不同于消费类电子和工业类电子，需要更有针对性的平台化设计软件。本文旨在介绍一种汽车电子行业的硬件自动化设计软件，主要用于车身控制系统的原理图设计。工程师只要根据输入输出信息，明确系统需求，就可以自动生成合理的电路原理图，在产品初期报价和设计的过程中，为硬件工程师节约大量时间，降低出错的风险。本课题不同于以往的其他同类软件，其他同类软件是通过例如遗传算法寻找合适的元器件组成特定功能的模拟电路，而本课题则是根据现有的典型电路，进行合理的搭配，，满足功能和性能需求。本软件根据汽车电子的特点和元器件的特殊要求，将自动化硬件设计向更为专业化的方向进一步尝试，不仅能够实现原理图的自动连线，还能根据输入输出负载要求，以满足功能为首要目标，兼顾成本优化，从众多类似的元器件中，选择合适的元器件和拓扑。
[Abstract]:With the rapid development of automobile industry, automotive electronics has become one of the core competitiveness of automotive products. To the present ABS (brake anti-lock braking system) PKE (passive wireless key), automatic parking system (ESPs) (body stabilization system, anti-clamp windows, massage seats, etc.), automotive electronic products have not only met the basic needs of the passengers, but also become safe and comfortable. The direction of personality development. All manufacturers also regard automotive electronic products as one of the most important basis for product positioning. It can be said that before there was any significant development in the field of physical chemistry, The development of automotive electronics determines the future of automobile. Automotive body electronics is a mature field in the automotive electronics industry at present, and it is also the most intuitive automotive electronic system that consumers feel at present. Automotive electronic products not only work in a very bad environment and complex working conditions, but also face the destruction of a lot of man-made errors, which makes the products have high requirements for reliability and error protection. Therefore, the automobile industry has established many technical standards. In order to ensure the safety and reliability of the car. The circuit for these standards requires a lot of experience and time for hardware engineers to design, after a lot of experiments, The design cost is high. In addition, the components of automobile products must go through the automobile grade certification, through a series of harsh tests, establish a perfect scientific research and production management process, in addition to the unique features of the car, Many chipmakers have designed a variety of chips for automotive electronics to choose from, so automotive electronics is different from consumer electronics and industrial electronics, so more targeted platform design software is needed. The purpose of this paper is to introduce a kind of hardware automation design software in automobile electronics industry, which is mainly used in the schematic design of car body control system. It can automatically generate reasonable circuit schematic, save a lot of time for hardware engineer and reduce the risk of error in the process of initial quotation and design. This subject is different from other similar software in the past. The other software of the same kind is to find the appropriate components and devices to form a specific function analog circuit through, for example, genetic algorithm, and this subject is based on the existing typical circuit, and carries on the reasonable collocation. According to the characteristics of automotive electronics and the special requirements of components, the software further tries to design automation hardware in a more professional direction, not only can realize the automatic wiring of schematic diagram, It can also select the appropriate components and topologies from many similar components according to the input and output load requirements, to satisfy the function as the primary goal, and to consider the cost optimization.
