如今许多我们习以为常的标配，最初都曾是豪华车的专属，从奔驰1951年首创的安全车身，到沃尔 沃1959年三点式安全带的普及，再到1981年奔驰的工程师将安全气囊作为选配安装在奔驰S级轿车 上。 当中国车企开始卷安全时，成为了豪华车最害怕的一集。 安全即豪华，豪华车的天花板该 定在哪儿 2025年9月12日，仰望汽车正式发布全尺寸行政豪华SUV仰望U8L鼎世版，售价128万元起。这款 集"鼎级安全、鼎级体验、鼎级豪华"于一身同时蕴含中国传统"鼎"文化的旗舰车型，包含着这家车 企"问鼎"豪华车市场的野心。 唐太宗李世民在《帝范》中写道："取法于上，得乎其中；取法于中，得乎其下；取法于下，则无所 得矣。"只有把天花板定的足够高，才能突破固有的认知和能力的上限。 豪华车的天花板该定在哪儿？U8L的答案是——鼎级安全。相比技术创新上已经很"顶"的U8，U8L 进行了347项升级。 事实上，豪华车的进化史，本质上就是一部人类建立在安全出行之上的极致追求史。 近年来，新能源技术加剧变革，越来越多的国产车企弯道超车冲击豪华车市场，从冰箱彩电大沙发到 安全、智能、长续航。国产豪华车品牌将燃油车时代被视为"极致"追求的"神器"一 ...

Core Concept - The article discusses the evolution and significance of drive-by-wire technology in the automotive industry, highlighting its advantages over traditional mechanical systems and its applications in modern vehicles [1][3][4]. Group 1: Definition and Origin of Drive-by-Wire Technology - Drive-by-wire technology refers to the replacement of traditional mechanical connections with electronic signals for vehicle control, enhancing precision and responsiveness [1][3]. - This technology originated from the aviation sector in the 1980s, specifically from fly-by-wire systems, which aimed to reduce weight and improve control capabilities [1][3]. Group 2: Applications of Drive-by-Wire Technology - The technology has expanded from initial applications in anti-lock braking systems (ABS) to include steering, throttle, and suspension systems, collectively known as drive-by-wire chassis technology [3][4]. - Examples of drive-by-wire systems include brake-by-wire, steer-by-wire, and electronic parking brakes, which replace traditional mechanical components with electronic controls [4][6][10][12]. Group 3: Advantages of Drive-by-Wire Technology - Drive-by-wire systems simplify mechanical structures, improve vehicle response times, and allow for more flexible control strategies, paving the way for advanced driver assistance systems [3][4]. - The modular design enabled by drive-by-wire technology offers cost-effective solutions for automotive manufacturing [3][4]. Group 4: Redundancy and Safety Measures - The article emphasizes the importance of redundancy in drive-by-wire systems to ensure safety in case of component failures, with examples such as the iBooster brake system and steer-by-wire systems employing multiple sensors for data validation [17][18]. - In extreme failure scenarios, these systems can still function through backup mechanisms, ensuring that vehicles can be safely controlled even when primary systems fail [17][18].
