继第四代ACR8主动控制安全带卷收器推出后,ZF LIFETEC又推出ACR8.S座椅集成式版本,进一步支持人机互联和自动驾驶发展趋势。集成至座椅后,为汽车座舱设计带来更多自由。此外,发生碰撞(位移)前,约束系统可以将乘员拉至更安全的位置。得益于电驱动单元,ACR8系统能够实现进一步的安全功能,例如在自动紧急制动等关键驾驶操作中快速收紧安全带。这种可逆的安全带卷收方式还能在运动驾驶模式时为驾驶员提供更好的支撑,从而提升驾驶乐趣。不仅如此,自动驾驶时,该安全带还可通过震动发出触觉警示,提示驾驶员接管车辆。

ACR8系列主动控制卷收器,在发生碰撞时,可通过电机和点烟器,自动收紧安全带


如果车辆传感器检测到不可避免的碰撞,烟火式安全带卷收器就会启动,安全带在几毫秒内将乘员上半身拉向座椅靠背。撞击过程中,乘员会被引向安全气囊,借助安全气囊吸收撞击能量,从而避免严重受伤。但这种卷收是不可逆的,只有在发生比较严重事故时才会与安全气囊一起触发,且仅使用一次。


ACR8.S的基本功能


所有ACR8系列产品的设计理念都是基于改善车辆乘员保护系统的碰撞前性能。为此,安全带更松弛,乘员始终保持或处于理想的位置。根据汽车制造商需求和车辆传感器配置,ZF LIFETEC的主动控制安全带卷收器可在碰撞发生前的毫秒内激活。ZF LIFETEC工程高级副总裁哈拉尔德·卢茨(Harald Lutz)解释说:“ACR8系列主动控制安全带卷收器将传统的烟火功能与可逆的电动卷收器集成在一起,以进一步提高碰撞前阶段的安全保护。此外,ACR8 的电子式控制选项也可提供额外的安全和舒适功能。”


模块化确保功能多样性


除上述功能外,ACR8.S还提供一系列模块化系统选项。目前有九种不同的配置组合可供选择。值得一提的是织带运动传感器和电驱动单元这两个组件是许多可选功能的核心构件。例如,它们可以发出触觉警示:自动驾驶时,主动控制卷收器可以通过高频震动安全带发出警告,提醒驾驶员接管车辆。其他情况下,安全带织带的高频脉冲可向乘员发出信号,提醒实施主动干预。卢茨emphasize:“在这些情况下,安全带系统贴近身体的脉冲是比显示屏或LED更有效的警示信号,可以最大限度地缩短反应时间。”


安全带的许多功能远远超出了其仅作为安全装置的作用。行驶过程中,乘员始终系好安全带,因此它应该紧贴乘员,但又不能限制乘员。ACR8.S的可选舒适功能允许在整个过程中安全带保持较低约束力,也就是说安全带只是轻贴在身体上。这一创新还能在运动驾驶模式时,提升操控性。ACR8.S 通过访问车辆导航数据,并在动态驾驶时收紧安全带,为乘员提供更多支撑。


更高级别自动驾驶


上述功能既适用于第四代ACR8,也适用于ACR8.S。ACR8.S设计更为紧凑,是座椅集成应用的理想之选。目前,ACR8.S在无B柱的敞篷车和双门轿跑车中颇具优势,未来应用到自动驾驶中也会非常有利。自动驾驶是新座舱概念发展过程中最重要的推动因素之一。如果安全带设置于座椅而非B柱上,将为座舱设计带来更多自由,使汽车座椅可以更自如地移动和旋转。

With the continuous enrichment of smart cockpit scenarios, passengers spend more and more time in the cockpit, putting forward higher and higher requirements for riding experience and comfort experience. When the journey is no longer a short period of time, how to optimize and improve seat comfort? Sex has become an important issue at the moment, and smart car seats have emerged. As a device that directly contacts the driver and passengers, seats play an important role in user experience and are also one of the factors that distinguish the level of automobile manufacturers. Today's high-end seats incorporate a wide range of applications for seat adjustment or seat movement, seat comfort (dynamic cushions, lumbar support, massage, heating, cooling and/or ventilation, seating assistance and personalized adjustment memory function), seat safety function, seat occupant perception (multiple built-in sensors can provide feedback information to the system). Due to the additional functions, modern seat modules have become as complex as body control modules and face similar challenges in terms of power supply, communication, sensing, activation and control, and quiescent current. In order to minimize the space requirements, power consumption and quiescent current of the management seat control module, functional integration becomes one of the important design factors. Therefore, smart car seats contain numerous motor drives and control units, and fabric selection and ergonomic design also need to be considered. The technical threshold is comparable to that of robots. In order to strengthen industry chain exchanges, jointly promote industry development, and learn about the latest product trends, Abant has established an automotive smart seat industry chain exchange group for everyone. Everyone is welcome to join the group for exchanges and discussions.
