Vehicle grade electronic components
车规级电子元器件
Automotive grade electronic components are different from consumer grade products. They operate in harsh environments such as outdoor, high temperature, high cold, and humid environments, and their design lifespan is generally 15 years or 200000 kilometers. The iteration cycle is much higher than that of consumer electronics by 2-3 years, and they also have high requirements for environment, vibration, impact, reliability, and consistency. Therefore, the corresponding cost is also higher than that of consumer and industrial grades.
车规级电子元器件汽车不同于消费级产品，会运行在户外、高温、高寒、潮湿等苛刻的环境，且设计寿命一般为 15 年或 20 万公里，迭代周期会远高于消费电子的2-3年，对环境、振动、冲击、可靠性和一致性要求也较高，因此相应成本也比消费级和工业级高。
Vehicle grade refers to the components that need to meet the requirements of on-board grade. The AEC-Q series standard is an industry recognized certification standard for vehicle grade components.
车规级，指要满足车载等级要求的元器件，AEC-Q系列标准是行业公认的车规元器件认证标准。
AEC is the Automotive Electronics Council of the United States, established by General Motors, Ford, and Chrysler to establish a common set of parts qualification and quality system standards. Q is the first letter of Qualification, and AEC-Q is the universal testing standard for automotive components organized by AEC.
AEC为美国汽车电子委员会（Automotive Electronics Council），是由通用、福特和克莱斯勒为建立一套通用的零件资质及质量系统标准而设立，Q为Qualification的首字母，AEC-Q是AEC组织的车规元器件通用测试标准。
AEC members include OEMs, component manufacturers Tire1, and component manufacturers, among others. AEC-Q is a voluntary certification and there is no official recognition. The test report is equivalent to a comprehensive “medical examination report” of the component.
AEC成员包括主机厂OEM，零部件厂商Tire1和元器件厂商等，AEC-Q是一种自愿性认证，不存在官方认可一说，测试报告相当于一份元器件全面的“体检报告”。
NXP, TI, MPS and other component suppliers perform AEC-Q verification tests on the components, and then self claim to meet AEC requirements to improve product competitiveness and premium capability. Tire1 selects and uses certified devices, and OEM and Tire1 are responsible for reviewing the AEC-Q report.
NXP、TI、MPS等元器件供应商对元器件执行AEC-Q验证测试，然后自我宣称满足AEC要求，以提高产品竞争力和溢价能力。Tire1选择并使用通过认证的器件，OEM和Tire1负责审核AEC-Q报告。
So, what are the characteristics of automotive grade electronic components?
那么，车规级的电子元器件有什么特点呢？
1. Reliability requirements: The design lifespan of automobiles is around 15 years, far exceeding the lifespan requirements of consumer electronics products. Currently, the electrification level of vehicles is already very high, especially the various control systems of electric vehicles, which are equipped with many ECU devices, which are composed of many electronic components. To ensure that the entire vehicle reaches a relatively high level of reliability, high requirements are placed on every component of the control system.
1、可靠性的要求：汽车设计寿命都在 15 年左右，远大于消费电子产品寿命要求，目前车辆的电气化程度已经非常高了，特别是电动汽车的各个控制系统，就配置了很多的ECU装置，ECU装置里又由很多的电子元器件构成。为保证车辆整车达到相当的高可靠性，对控制系统组成的每一个部分的要求都很高的。
2. Unification requirement: Nowadays, cars are produced on a large scale, and manufacturers can produce hundreds of thousands of standardized vehicles per year. Therefore, there is a high requirement for uniformity in product quality. For automotive products with complex component compositions, a unified and consistent electronic component will avoid safety hazards for the entire vehicle.
2、统一性要求：现在的汽车都是大规模生产方式，厂家一款定型车辆一年可以生产数十万辆，所以就对产品质量的统一性要求非常高，对于零部件组成复杂的汽车产品来说，所以统一的、一致的电子元器件将会避免整车出现安全隐患。
3. Standard requirements: In order to meet the complex requirements of electronic components for automotive products and various electronic control systems, the emergence of vehicle level certification means that the production, manufacturing, and performance of components can meet specific automotive industry standards. The most internationally recognized standard is the International Association of Automotive Electronics (AEC) standard.
3、规范标准要求：为满足汽车产品及各个电控系统对电子元件的复杂要求， 出现的车规级认证意味着元器件的生产制造和性能能够符合特定的汽车行业标准，比较得到国际公认的就是国际汽车电子协会 AEC 的标准。
