在底盘实验室，1000余个零部件性能指标被转化为130余项可量化KPI，40个传感器实时捕捉100多个方向的振动、倾角与压力数据，最终凝结成"驾控黄金 标准"五大维度：驾乘舒适性要"过减速带如履平地"，安全感需"极端路况下可预期"，掌控感要"始终有余力应对突发"，运动性与精准性则需在高低速场景 无缝切换。 此外，好的底盘需要一步步打磨出来，梅赛德斯-奔驰底盘研发严格遵循CAD、产品验证、数字原型测试、原型车测试、数字孪生、量产车验证6大步骤，数 字仿真+实车锤炼缺一不可，历经4年打磨，以完善系统的研发流程，造就奔驰标准的好底盘。 齐鲁晚报·齐鲁壹点 陈颖 2025年，梅赛德斯-奔驰在华研发与生产迈入第20个年头。8月5-7日，一场以"奔驰标准"为名的科技日活动在北京开启，没有炫目的概念，只有对"好 开"与"好坐"的深度解构。当底盘的毫米级调校数据与座椅的万次测试报告被呈现，奔驰的豪华，藏在139年造车积淀里的执着便一览无余——那是对每个零 件的较真，是对每次体验的打磨，更是对"标准"近乎偏执的坚守。 底盘的玄学：从数据到体感的精密博弈 奔驰认为，底盘的调校是一门玄学的艺术。作为汽车的"动态灵魂"，奔驰对底盘的 ...

Group 1 - The article discusses the complexity of automotive chassis technology, focusing on the variable gear ratio steering (VGRS) system as a specific configuration within the chassis system [1] - VGRS allows for dynamic adjustment of the steering ratio based on vehicle speed and steering angle, optimizing driving experience for both low-speed maneuverability and high-speed stability [6][13] - Traditional fixed gear ratio steering systems (CGR) can lead to challenges in handling at different speeds, necessitating the development of VGRS to address these issues [4][6] Group 2 - VGRS can be implemented through mechanical adjustments to the gear shape or through electronic means, such as steer-by-wire technology [8] - Mechanically, VGRS adjusts the density of the steering rack teeth to change the steering ratio, but it lacks the ability to adapt to vehicle speed [9] - An example of an advanced VGRS structure includes a harmonic drive reducer that allows for steering ratio adjustments based on vehicle speed and stability control [11][13]

Group 1: Revenue Growth and Performance - The company's revenue growth in 2024 and Q1 2025 is primarily driven by product structure optimization and increased value per vehicle [1] - Profit growth is attributed to effective cost control, leading to a decrease in expense ratio relative to revenue [2] - The company maintains a strong outlook for sustainable growth, focusing on smart and electric technology routes [2] Group 2: Production and Technology Development - The company has solid technical reserves in steer-by-wire technology and is progressing with several mainstream automakers, with some projects expected to be mass-produced by 2026 [2] - The steering industry is undergoing a competitive restructuring due to the acceleration of vehicle electrification and intelligence [2] - The company plans to enhance R&D investment to strengthen its position in the smart steering sector [2] Group 3: Market Expansion and Client Base - The company is actively expanding its international market presence and is in the process of qualification certification with several well-known international automakers [2] - Major clients in the passenger vehicle sector include traditional automakers like Chery and Geely, as well as new players like NIO and Li Auto [3] - The company is optimistic about revenue growth in 2025, driven by increasing penetration of new energy vehicles and demand for intelligent steering systems [3] Group 4: Future Product Launches and Collaborations - New production capacity in 2025 will focus on electric steering columns and R-EPS [3] - The company is engaged in technical exchanges for steering technology with various clients in the unmanned logistics vehicle sector [3] - The company has developed technology reserves in rear-wheel steering, with projects expected to be mass-produced by 2026 [3]

采埃孚CEO回应独立拆分电驱动业务：希望与合作伙伴产生协同效应，不断 将业务重心向中国转移 每经记者 范文清 每经编辑 余婷婷 继德国汽车零部件巨头大陆集团宣布，将汽车业务板块拆分，并计划于今年9月独立上市后，采埃孚集团也在3月20日宣布，公司正在评估将电驱动技术事业 部进行独立拆分的可行性。 "采埃孚集团的产品线很多，但我们有一个总体策略，就是必须在其所经营的领域里，排到行业前三名。比如，我们在底盘领域、商用车领域行业第一，在 工业技术领域位列第三，在售后领域我们排名第二。如果做不到这一点，可能就无法实现盈利。为了提高这些业务领域的竞争力，我们可能要寻找一些合作 伙伴，把其排名拉到行业前一二名的位置。所以我们独立拆分电驱动业务的原因之一就是提高其竞争力水平。"3月24日，采埃孚集团首席执行官（CEO）柯 皓哲博士（Dr. Holger Klein）在接受《每日经济新闻》记者采访时回应称。 事实上，这并不是采埃孚近年来第一次对旗下业务进行拆分。之前，采埃孚也曾对其车桥、中间件和被动安全系统等业务板块进行过重组，取得了不错的效 果。例如，通过与富士康的合作，采埃孚的车轴总成业务正在长足发展，拥有了更多客户和新的 ...
