感知核心:轮胎技术的飞跃
住友橡胶提及的评估标准是ASPICE(汽车软件过程改进和能力评估)系统,该系统是在德国汽车工业协会(VDA)的主导下开发的。源自ISO/IEC 15504国际标准,它已成为全球汽车软件开发的“准入码”。
该系统将企业能力划分为0至5级,其中第3级(已建立)标志着从“项目级管控”向“组织级成熟度”的转变。该级别要求建立跨项目的标准化过程库,既能实现统一复用,又能根据具体情境灵活调整。
这一级别的核心价值在于应对汽车软件质量和效率的挑战。数据显示,通过ASPICE三级评估的企业,其软件回归测试周期平均缩短了30%,现场故障率下降了45%。
全球前十大汽车制造商甚至将此设定为一级供应商的强制性门槛。对于住友橡胶而言,这意味着其轮胎传感技术软件开发流程已达到与主流汽车制造商相媲美的标准化水平。
The core value of this level lies in addressing the challenges of automotive software quality and efficiency. Data shows that companies that pass the ASPICE Level 3 assessment experience an average 30% reduction in software regression testing cycles and a 45% drop in field failure rates.
The top 10 global automakers have even established this as a mandatory threshold for Tier 1 suppliers. For Sumitomo Rubber, this signifies that its tire sensing technology software development process has reached a standardized level on par with mainstream automakers.
“核心感知”技术:如何开启通往第三级之门?
住友橡胶的SENSING CORE技术并非单一传感器,而是一个集成了硬件感知与软件算法的智能系统。其之所以能达标,源于两项关键突破:
在流程标准化方面,该技术建立了覆盖“感知-分析-预警”全链条的开发规范。例如,为收集轮胎抓地力与磨损等核心数据,团队定义了12项基础指标和八种验证算法。
所有参数均与统一需求管理平台(例如Jama Connect)相连,实现了从需求提交到测试验收的全程可追溯性。这一标准化设计使得技术能够适应不同车型——从苏州相城自动驾驶测试车辆到欧美车队,从而实现了核心模块的快速复用。
在组织复用性方面,住友橡胶整合了25年轮胎压力预警系统(DWS)研发经验,建立了跨区域技术共享机制。其位于德国的欧洲总部与中国常熟工厂可同时访问算法库。
例如,针对冰雪路面的抓地力模型,既借鉴了北欧的测试数据,又融合了中国东北地区的实地参数。这种可复用性是ASPICE三级标准的核心要求。更重要的是,该技术解决了传感器能源瓶颈:通过利用轮胎转动发电,无需电池即可实现数据的持续传输,从而进一步降低了跨场景适应的成本。
In terms of organizational reusability, Sumitomo Rubber has integrated 25 years of experience in tire pressure warning system (DWS) R&D to establish a cross-regional technology sharing mechanism. Its European headquarters in Germany and its Changshu, China, factory can simultaneously access algorithm libraries.
For example, the grip model for icy and snowy road conditions is derived from both Nordic test data and incorporating field parameters from Northeast China. This reusability is a core requirement of ASPICE Level 3. More importantly, this technology addresses the sensor energy bottleneck: by utilizing tire rotation to generate electricity, continuous data transmission is possible without batteries, further reducing the cost of cross-scenario adaptation.
突破背后:智能新时代的来临
Behind the Breakthrough: A New Era for the Smart 轮胎行业
住友橡胶的这一成果是“软件定义轮胎”趋势的一个缩影。在自动驾驶与网联汽车(CASE)浪潮的推动下,轮胎正从被动的承重部件转变为主动的感知节点,软件能力成为核心竞争力所在。
SENSING CORE技术已实现五大核心功能:实时监测胎压、负载、路况、磨损及车轮松动情况,甚至能借助AI算法预测潜在的车辆故障,每年为每辆车节省2500美元的维护成本。
这一成就将进一步重塑行业的供应链格局。目前,大多数轮胎企业的感知技术仍停留在ASPICE 2级(管理级),仅能实现单项目流程控制。
然而,住友橡胶的Level 3能力使其有资格与智能驾驶公司进行深度合作。例如,其技术能向自动驾驶系统输出“隐形数据”。在大雨遮挡摄像头视线时,轮胎对路面摩擦系数的感知能为安全决策提供关键补充。
This achievement will further reshape the industry's supply chain landscape. Currently, most tire companies' sensing technology remains at ASPICE Level 2 (managed level), enabling only single-project process control.
However, Sumitomo Rubber's Level 3 capability qualifies it for in-depth collaboration with intelligent driving companies. For example, its technology can output "invisible data" to autonomous driving systems. When cameras are obscured by heavy rain, the tire's perception of the road's friction coefficient can provide a critical supplement for safety decision-making.
