每经记者｜段思瑶 每经编辑｜裴健如 "消费级和车规级芯片差别很大，汽车不是快消品……"日前，一条由一汽奥迪销售有限责任公司执行副总经理李凤刚出镜的视频，将"消费级芯片和车规级 芯片差别"这个隐秘的知识点推向了公众视野。 在这条视频中，李凤刚以消费级芯片和车规级芯片的安全余量举例称，"汽车在高速行驶中一旦发生问题，后果往往是致命的。消费级芯片的缺陷率允许达 到500PPM（即每100万件中允许有500件出现故障），而车规级芯片的缺陷率通常要求低于百万分之一"。 相较车规级芯片的高标准、严要求，消费级芯片的准入门槛要低得多。"目前消费级芯片还没有强制的安全认证要求。"上述某芯片企业研发人员告诉记者， 消费级芯片主要以性能与成本优先，缺陷率允许≤500 DPPM。 另外，在工作适应环境方面，消费级芯片一般工作在室内舒适环境，工作温度范围通常为0℃到70℃，而车规级芯片则需适应汽车所处的复杂环境，其工作 温度要求更为宽泛，一般为-40℃到150℃。 "从安全性等方面综合考虑，消费级芯片的确不如车规级芯片。"上述某芯片企业研发人员认为，应用在智能座舱和智能驾驶等领域的关键芯片，必须采用车 规级芯片，以确保车辆安全。 消 ...

Core Viewpoint - The recent controversy surrounding Xiaomi's YU7 smart cockpit, which utilizes consumer-grade chips instead of automotive-grade chips, has sparked discussions in the industry about the implications of this trend [2][3]. Group 1: Consumer-grade vs. Automotive-grade Chips - Consumer-grade chips, like Qualcomm's Snapdragon 8 Gen 3 used in Xiaomi YU7, prioritize performance and cost, while automotive-grade chips focus on safety and reliability, adhering to ISO 26262 standards [4][5]. - Automotive-grade chips must pass AEC-Q100 certification with a defect rate of ≤10 DPPM, whereas consumer-grade chips have a higher defect rate allowance of ≤500 DPPM [4]. - The operating environment for automotive-grade chips ranges from -40℃ to 150℃, while consumer-grade chips are limited to 0℃ to 70℃ [4]. Group 2: Industry Trends and Implications - The increasing demand for in-car entertainment and smart features has led to a higher reliance on consumer-grade chips, especially when automotive-grade chip production cannot keep pace with market needs [6]. - Some automotive companies are modifying consumer-grade chips to enhance their safety and reliability, as seen with Xiaomi YU7's thermal reinforcement and software scheduling [7]. - Despite the short-term benefits of using consumer-grade chips, experts warn that this approach may be detrimental in the long run due to safety concerns and the shorter lifespan of these chips compared to automotive-grade options [8][9]. Group 3: Future of Chip Usage in Automotive Industry - The automotive industry is expected to revert to using exclusively automotive-grade components as the demand for higher safety and reliability increases, particularly with the rise of integrated cockpit solutions requiring ASIL D safety levels [9][10]. - Leading chip manufacturers are expanding their capabilities to produce both consumer-grade and automotive-grade chips, indicating a shift in focus towards the automotive-grade market [9][10].
