ISO 26262为汽车安全提供了一个生命周期(管理、开发、生产、经营、服务、报废)理念,并在这些生命周期阶段中提供必要的支持。该标准涵盖功能性安全方面的整体开发过程(包括需求规划、设计、实施、集成、验证、确认和配置)。
ISO 26262标准根据安全风险程度对系统或系统某组成部分确定划分由A到D的安全需求等级(Automotive Safety Integrity Level 汽车安全完整性等级 ASIL),其中D级为最高等级,需要最苛刻的安全需求。伴随着ASIL等级的增加,针对系统硬件和软件开发流程的要求也随之增强。对系统供应商而言,除了需要满足现有的高质量要求外还必须满足这些因为安全等级增加而提出的更高的要求。
目前全球知名的整车厂商已经对电气器件、电子设备、可编程电子器件的采购提出的具体的功能安全要求和ASIL等级要求。参加我们的培训,将使安全系统及产品符合所需 ASIL(车辆安全完整性等级)、符合国际市场要求规范,并与国际功能安全技术接轨,强化客户对产品的信赖度,提升产品内在价值。
