KiRoad Wireless HDR:适用于车辆研发的全新无线车轮六分力测量解决方案


瑞士温特图尔,2021年6月——奇石乐集团发布全球款无线车轮六分力测量系统,创新产品将全面简化车辆动力学测试、耐久性测试和轮胎测试流程KiRoad Wireless HDR测量系统具有2.4G频段无线局域网(WLAN)远场遥测功能,且能够与所有型号的RoaDyn车轮六分力传感器配合使用。

车辆研发过程中,研发人员可使用高精度车轮六分力传感器(WFT)直接测量轮毂上的车轮力和力矩;这些测量数据不但对耐久性测试极为重要,也可用于评估车辆的动力学表现、描述轮胎性能。RoaDyn系列车轮六分力传感器率先使用近场遥测技术完成数据传输——今天,奇石乐测量技术专家再次实现全新突破。

KiRoad Wireless HDR(高数据率)测量系统采用远程无线传输技术传输车轮力测量数据,用户无需耗费时间进行车辆内外部的线缆安装与调试。通过部署该系统,汽车和轮胎制造商、汽车零部件供应商、科研机构和赛车团队等用户可全面简化测量方案的配置及操作过程,将节省出来的宝贵时间投入道路测试中。

无线测量——无需在车辆上安装任何突出零件

模块化测量系统KiRoad Wireless HDR由车载测量单元(电子单元)、车轮电子单元和旋转编码器三个组件构成;该等组件与Kistler车轮六分力传感器(该传感器已成为行业标准)相兼容。KiRoad Wireless HDR系统的主要特点及优势包括:

  • 无线局域网数据传输(无线传输标准:IEEE 802.11n)
  • 无需安装突出零件,不会改变车辆外观及空气动力学特性
  • 可更换电池组,即使-20°C环境下仍可持续供电至少4小时(适用于冬季测试)
  • 支持CAN、DTI和以太网等多类型数字数据输出
  • 可通过KiCenter软件或浏览器实现系统配置和测量结果可视化

KiRoad Wireless HDR系统采用全新的旋转编码器概念,用户无需在车辆外部安装任何设备。车轮测量单元配备集成式计算与传输单元,且采用防水设计,易于安装和移除,最大程度为测试工程师节省配置时间。

为Kistler RoaDyn车轮六分力传感器轻松加装KiRoad Wireless HDR系统

用户可为所有RoaDyn车轮力传感器加装KiRoad Wireless HDR系统。换言之,奇石乐客户可为所有车轮六分力传感器增加无线测量功能,既可测量车轮在三个空间方向上产生的所有力和力矩,也能够测量车轮转角和角速度。我们已与试用客户共同开展大量实用测试,证明新系统能够满足客户的所有期望。KiRoad Wireless HDR系统现已上市。

Cable-free measurements – with no protruding parts on the vehicle

This modular system consists of three components that are compatible with the 6-component wheel force transducers from Kistler, already established as the industry standard: the onboard unit (electronics), the wheel unit and the rotary encoder. Key features and benefits of KiRoad Wireless HDR:

  • Data transmission via WLAN (wireless standard: IEEE 802.11n)
  • No protruding parts – so vehicle contours are unchanged
  • Replaceable battery pack with minimum capacity of 4 hours at –20°C (e.g. for winter tests)
  • Digital data output for all channels via CAN, DTI and Ethernet
  • System configuration and visualization of measurement results in KiCenter software or browser

A new rotary encoder concept used with the KiRoad Wireless HDR eliminates the need to attach any equipment to the outside of the vehicle. The wheel unit, with its integrated calculation and transmitter unit, is designed to be waterproof and is easy to install and remove, thus minimizing setup time for the test engineer.

KiRoad Wireless is easy to retrofit on Kistler RoaDyn WFTs

All RoaDyn WFTs that are currently in operation can be equipped with KiRoad Wireless HDR. This gives Kistler's customers the benefits of a cable-free measuring system for all 6-component WFTs: they can measure all forces and moments on the wheel in each of the three spatial directions, as well as wheel angle and angular speed. The new system met every expectation throughout intensive practical testing with pilot customers, and KiRoad Wireless HDR is available as of now.
