【摘要】：隨著汽車工業(yè)的迅猛發(fā)展，汽車電子已經(jīng)成為汽車產(chǎn)品的核心競爭力之一。從最早的車燈、電動雨刷，到現(xiàn)在的ABS（剎車防抱死系統(tǒng)）、PKE（被動無線鑰匙）、自動泊車系統(tǒng)、ESP（車身穩(wěn)定系統(tǒng)）、防夾車窗、按摩座椅等，汽車電子產(chǎn)品已經(jīng)不僅滿足乘車者的基本需求，而是向著安全、舒適、個性的方向發(fā)展。各個廠商也紛紛將汽車電子產(chǎn)品作為產(chǎn)品定位的最主要依據(jù)之一�？梢哉f，在物理化學(xué)領(lǐng)域沒有重大發(fā)展之前，汽車電子的發(fā)展決定了汽車的未來。汽車車身電子是目前汽車電子行業(yè)發(fā)展比較成熟的一個領(lǐng)域，也是目前消費者感受最直觀的汽車電子系統(tǒng)。 汽車電子產(chǎn)品不僅工作環(huán)境非常惡劣、工況復(fù)雜，還要面對很多人為失誤的破壞，使得產(chǎn)品對于可靠性和錯誤保護的要求很高。因此汽車行業(yè)建立了眾多技術(shù)標(biāo)準(zhǔn)，以保證汽車的安全性和可靠性。針對這些標(biāo)準(zhǔn)的電路需要硬件工程師用豐富的經(jīng)驗和大量的時間，經(jīng)過大量的試驗來設(shè)計，其設(shè)計成本居高不下。另外汽車產(chǎn)品的元器件都必須經(jīng)過汽車級認(rèn)證，通過一系列苛刻的試驗，建立完善的科研和生產(chǎn)管理流程。再加上汽車功能的獨特性，使得很多芯片廠商為汽車電子設(shè)計了品種豐富的芯片以供選擇。因此汽車電子不同于消費類電子和工業(yè)類電子，需要更有針對性的平臺化設(shè)計軟件。 本文旨在介紹一種汽車電子行業(yè)的硬件自動化設(shè)計軟件，主要用于車身控制系統(tǒng)的原理圖設(shè)計。工程師只要根據(jù)輸入輸出信息，明確系統(tǒng)需求，就可以自動生成合理的電路原理圖，在產(chǎn)品初期報價和設(shè)計的過程中，為硬件工程師節(jié)約大量時間，降低出錯的風(fēng)險。本課題不同于以往的其他同類軟件，其他同類軟件是通過例如遺傳算法尋找合適的元器件組成特定功能的模擬電路，而本課題則是根據(jù)現(xiàn)有的典型電路，進行合理的搭配，，滿足功能和性能需求。本軟件根據(jù)汽車電子的特點和元器件的特殊要求，將自動化硬件設(shè)計向更為專業(yè)化的方向進一步嘗試，不僅能夠?qū)崿F(xiàn)原理圖的自動連線，還能根據(jù)輸入輸出負(fù)載要求，以滿足功能為首要目標(biāo)，兼顧成本優(yōu)化，從眾多類似的元器件中，選擇合適的元器件和拓?fù)洹?br/>[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.
