Description

车载雷达标定设备

技术领域
本申请涉及汽车维修及设备标定技术领域，尤其涉及一种车载雷达标定设备。
背景技术
在汽车高级驾驶辅助系统(Advanced Driver Assistant Systems，ADAS)领域，自适应巡航系统(Adaptive Cruise Control，ACC)是一项普遍使用的辅助功能。其具体工作原理是，通过车载雷达实时对前方车辆进行测距，将自身车速与前方车速进行比对，同时控制本车的油门、制动等动力系统，使本车始终与前车保持恒定的安全距离。因此车载雷达的作用在ACC功能的实现中至关重要，除去雷达本身的测定性能外，其安装位置、安装角度都决定其最终的测量数据的正确性和精准性。而上述安装位置及安装角度，会因车辆使用产生的震动、碰撞等不可控因素产生变化，故在汽车维修及和设备标定领域，尤其是ACC功能标定中，车载雷达的标定是核心内容。目前车载雷达的标定，多为后装标定，即在车辆出厂交付用户使用一段时间后，因客观原因，需要对车载雷达进行标定。
车载雷达的标定通常需要雷达标定辅助设备，需要根据车载雷达在车上的不同位置来定位雷达标定辅助设备。而车载雷达一般安装在车前杠的不同位置，导致不同车型的车载雷达左右位置、上下高度不一，以致增加了定位雷达标定辅助设备的难度，也增加了雷达标定操作的复杂度。

可以理解地，上述情况仅为一种雷达标定辅助设备的特定应用场景。雷达标定辅助设备仅需实现能够反射雷达波，以实现对车载雷达进行标定即可。对于雷达标定辅助设备的其他附加功能，本申请实施例不予限定。
雷达标定辅助设备200可以挂载在滑动件30上，其可以随滑动件30一起运动。雷达标定辅助设备200可以在利用标定激光器500完成对滑动件30的定位后，挂载在滑动件30上，在此情况下，雷达标定辅助设备200可以无需设置通孔。或者，雷达标定辅助设备可以在支架相对于车载雷达调节位置之前，挂载在滑动件30上，在此情况下，雷达标定辅助设备200可以设置通孔，以允许标定激光器500能够发出激光束。
雷达标定辅助设备200于滑动件30的连接方式仅需满足雷达标定辅助设备200可以随滑动件30运动即可，对其具体的实现结构不予限定。
对于对雷达标定辅助设备200或滑动件30进行定位，可以通过两种方式实现。
第一种，标定激光器500将激光束发射至待标定汽车的车载雷达上，以实现对雷达标定辅助设备200的定位。例如，标定激光器500将激光束发射至车载雷达上，其可发送至车载雷达面向支架装置100的一面的预设位置上。或者，发送至其他能够对准车载雷达的位置上，在此不予限定。例如，标定激光器500位于滑动件30的中心部，其发射的激光束经过滑动件30的中心点，通过调节横梁组件的高度和滑动件相对于横梁组件的水平位置，使发射的激光束落在车载雷达的上述面的中心点上，即实现对雷达标定辅助设备200的定位，使其对准车载雷达，以进一步利用雷达标定辅助设备200对车载雷达实现算法或软件校准。
进一步地，还可以利用辅助定位装置，使雷达标定辅助设备200的定位更加准确。辅助定位装置能够指导激光束落在车载雷达上的位置，使其能够准确到达车载雷达上的预设位置，如上述中心点上。一些实施例中，辅助定位装置可以为车载雷达的一部分，其不影响车载雷达发射雷达波，并能够指示车载雷 达在标定过程中的预设位置。另一些实施例中，辅助定位装置可拆卸地安装于车载雷达上，当需要对雷达标定辅助设备200进行定位时，辅助定位装置覆盖于车载雷达面向支架装置的面上，其上可以设置有预设位置的标识，如刻度尺，标识点，通孔等，能够使激光束准确落到预设位置的标识上。当对雷达标定辅助设备200的定位完成后，可以移除雷达标定辅助设备200，进而可以利用定位后的雷达标定辅助设备200对车载雷达进行标定。
第二种，标定激光器500向车载雷达发送激光束，车载雷达可以利用自身或另外配置的反射镜，反射该激光束，使该激光束反射回滑动件30的预设位置上，进而对雷达标定辅助设备200进行定位。例如，可以利用横梁组件和滑动件调节雷达标定辅助设备200的位置，使反射后的激光束回落至标定激光器500的发射点，即实现对雷达标定辅助设备200的定位。
上述两种方式中，还可以在雷达标定辅助设备200调节位置的过程中，确定激光束落在的位置与预设位置的落差，并基于该落差提示操作者。
进一步地，在对雷达标定辅助设备200进行位置调节之前，可以先摆正支架装置100的位置，例如，调节支架装置100相对于车辆的距离，使支架装置100平行拜访于车前，调节支架装置100的俯仰角等。本申请实施例中描述的调节支架的方式仅为示例性地，对于任何一种支架调节方式，均落入本申请实施例的范围中。例如，当雷达标定辅助设备200为雷达标定板等对其俯仰角有限制的装置时，可以在调节雷达标定辅助设备200的俯仰角后，再调节雷达标定辅助设备200的位置。或者，先调节雷达标定辅助设备200的位置，再调节雷达标定辅助设备200的俯仰角。在此不予限定。请一并参阅图8和图9，所述光阑300包括固定座310和滑动光阑320。

所述滑动光阑320包括光阑部322和滑动槽部324。所述光阑部322大致为平板状，设有条状光阑槽3222，用于允许激光束穿过。所述光阑槽3222的宽度比所述车载激光器400发射的激光点直径略小，以便于检测激光束是否正好通过光阑槽3222。所述滑动槽部324安装于光阑部322，其为条状，套设于所述固定支架314。所述滑动槽部324可相对于所述固定支架314滑动。所述滑动槽部324设有条状开槽3240，所述锁紧把手316穿过所述开槽3240，用于将所述滑动光阑320稳定的固定在所述固定座310。

请参阅图12，在对待标定汽车的车载雷达进行标定的第一步骤中，所述汽车800水平设置(也即所述汽车800停放在一水平面)，通过所述滚轮112将所述支架装置100移动到待标定汽车800前部，距离在1米左右，使所述导轨212与汽车800车轴大致相平行。观察所述水平仪214，调节所述高度调节件114，使所述导轨212水平设置。将所述雷达标定辅助设备200安装于所述滑动件30，此时所述雷达标定辅助设备200平行于所述板体302，所述激光出射孔502与所述通孔202对齐。将所述雷达标定辅助设备200和所述滑动件30沿所述导轨212移动至待标定汽车800的一侧。在待标定汽车800的一个后轮安装好轮毂夹，并安装所述车载激光器400，打开所述车载激光器400，使所述车载激光器400发出的激光束照射在所述雷达标定辅助设备200的光反射面上。取所述光阑300，并将所述光阑300放置在所述车载激光器400与所述雷达标定辅助设备200的中间，并使所述光阑部322与激光束垂直。将所述光阑槽3222调节与所述车载激光器400的发射孔4302高度一致。调节所述车载激光器400的出射角度，使所述车载激光器400沿水平方向发出激光束，并且所述车载激光器400发出的激光束平行于待标定汽车800的中轴面，适当移动光阑300的位置，使激光束能够从所述光阑槽3222正中通过。根据实际情况，通过滑动所述滑动件30和/或调节所述导轨212的高度，从而调节所述雷达标定辅助设备200的位置，使此时的激光束能够照射到所述雷达标定辅助设备200上。观察反射回的激光点位置，移动所述支架装置100和调节所述高度调节件114，使所述雷达标定辅助设备200反射的激光束正好能沿原路返回，投射到所述车载激光器400的发射孔4302。此时，完成对所述雷达标定辅助设备200的竖直面标定，所述导轨212垂直于所述汽车800的中轴面，所述雷达标定辅助设备200和所述板体302竖直设置，并且也垂直于所述汽车800的中轴面。
在本实施例中，所述汽车800水平设置时，所述汽车800的中轴面竖直设置，并且所述汽车800相对于所述中轴面对称。
在对车载雷达进行标定的第二步骤中，打开所述标定激光器500，从所述激光出射孔502发射出的激光束通过所述雷达标定辅助设备200的通孔202。调节所述导轨212的高度和水平滑动所述滑动件30，使从所述激光出射孔502出射的激光束照射在车载雷达表面的正中间，关闭所述标定激光器500，至此，完成了雷达标定辅助设备的定位。
在对车载雷达进行标定的第三步骤中，根据不同的雷达标定需求，可以挂载不同雷达标定辅助设备于所述滑动件30，以对所述待标定汽车800的车载雷达进行标定。
可以理解的是，在一些其它实施例中，可以使用现有技术中的竖直面标定装置对所述雷达标定辅助设备200和所述板体302进行竖直面标定，使得所述雷达标定辅助设备200和所述板体302垂直于汽车的中轴面，将所述雷达标定辅助设备200和所述标定激光器500移动至车载雷达前方，利用所述标定激光器500发出激光束穿过所述雷达标定辅助设备200的通孔202，可对雷达标定辅助设备进行定位。本领域所属技术人员应明白，若利用现有技术中的竖直面标定装置对所述雷达标定辅助设备200和所述板体302进行竖直面标定，不需要所述雷达标定辅助设备200反射光束，则所述雷达标定辅助设备200不需要光反射面，所述雷达标定辅助设备200仅需为板状，并具有所述通孔202即可，所述雷达标定辅助设备200可为塑料板或铝板等。
在本实施例中，所述标定激光器500安装于所述第二表面3024，且所述标定激光器500全部或部分收容于所述安装通孔3026，使得所述标定激光器500可与所述滑动件30同步水平滑动，方便定位不同车型的雷达标定辅助设备，可方便实现对不同车型的车载雷达进行标定。
另外，利用所述雷达标定辅助设备200、光阑300以及车载激光器400可实现所述雷达标定辅助设备200和所述板体302的竖直面标定，所述雷达标定辅助设备200即可以用于其竖直面标定，又可以用于定位雷达标定辅助设备，减少了所述车载雷达标定设备600的元件数量，降低了成本，也简化标定操作。
而且，用于挂载雷达标定辅助设备的所述滑动件30可沿所述导轨212水平滑动，在一辆汽车存在多个车载雷达时，完成一个车载雷达的标定后，可滑动所述滑动件30至另一车载雷达的前方，以对另一车载雷达进行标定操作，不需要再对所述导轨212进行水平标定，可方便对一辆汽车的多个车载雷达进行标定。
最后应说明的是：以上实施例仅用以说明本发明的技术方案，而非对其限制；在本发明的思路下，以上实施例或者不同实施例中的技术特征之间也可以进行组合，步骤可以以任意顺序实现，并存在如上所述的本发明的不同方面的许多其它变化，为了简明，它们没有在细节中提供；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
