示例性实施例
图1为本公开轨迹跟踪控制器的测试方法一个实施例的流程图。如图1所示，该实施例方法包括：S100、S110、S120和S130。下面对各步骤进行详细描述。
S100、获取第一移动设备处于未受控于待测试轨迹跟踪控制器的行驶状态时，第一移动设备的多个定位信息和多个运动状态信息。
在一个可选示例中，本公开中的S100中的第一移动设备为用于形成测试参考轨迹的移动设备。用于形成测试参考轨迹的移动设备是指可以通过驾驶或者遥控或者操作等控制方式，实现移动的设备。用于形成测试参考轨迹的移动设备包括但不限于：车辆、机器人以及机器臂等，从而有利于使本公开提供的技术方案可以适用于多种应用场景中。所述第一移动设备处于未受控于待测试轨迹跟踪控制器的行驶状态，为所述第一移动设备处于非自动驾驶模式(如驾驶员驾驶模式)的行驶状态，该情形下获得的测试参考轨迹相当于记录了驾驶员的驾驶行为。所述第一移动设备处于未受控于待测试轨迹跟踪控制器的行驶状态，也可以为所述第一移动设备处于除该待测试的轨迹跟踪控制器控制之外的其他处于控制器控制下无人驾驶的行驶状态，等等。本公开中的测试参考轨迹是第二移动设备中的待测试轨迹跟踪控制器需要使第二移动设备跟踪行驶的轨迹。
可选的，在用于形成测试参考轨迹的第一移动设备为车辆时，该车辆可以是能够实现自动驾驶控制的车辆；当然，也可以是不能够实现自动驾驶控制，而只能基于驾驶员的驾驶行为而行驶的车辆。即该车辆可以通过驾驶员的驾驶行为，来形成测试参考轨迹。本公开通过利用驾驶员驾驶车辆的方式来形成测试参考轨迹，由于驾驶员可以根据测试需求驾驶车辆形成多种样式的测试参考轨迹，因此， 本公开有利于提高形成测试参考轨迹的便捷性以及多样性，且有利于为轨迹跟踪控制器的测试提供更符合人类驾驶习惯的测试参考轨迹。
可选的，在用于形成测试参考轨迹的第一移动设备为机器人时，该机器人可以是为顾客提供服务的机器人等。在用于形成测试参考轨迹的移动设备为机器臂时，该机器臂可以是生产线上的机器臂等。机器人或者机器臂可以通过人工遥控等人工操作方式，来形成测试参考轨迹。本公开通过利用遥控等人工操作方式来形成测试参考轨迹，由于人工操作可以根据测试需求控制机器人形成多种样式的测试参考轨迹，因此，本公开有利于提高形成测试参考轨迹的便捷性以及多样性，且有利于为轨迹跟踪控制器的测试提供更符合人类操作习惯的测试参考轨迹。
需要特别说明的是，在下述实施方式中，有时是以车辆为例，对本公开提供的轨迹跟踪控制器的测试的技术方案进行说明的，然而，这并不表示本公开提供的技术方案仅适用于车辆。
在一个可选示例中，本公开的第一移动设备上可以设置有定位装置，通过定位装置来接收定位信号(如卫星定位信号等)，这样，本公开可以通过定位装置接收到的定位信号，来获得第一移动设备的定位信息。可选的，第一移动设备的定位信息包括但不限于：定位时间(如定位时间戳)以及第一移动设备的位置信息。第一移动设备的位置信息包括但不限于：第一移动设备在真实世界坐标系中的坐标。可选的，真实世界坐标系可以为二维坐标系。例如，真实世界坐标系包括但不限于：UTM(Universal Transverse Mercator，通用横轴墨卡托投影)坐标系。如第一移动设备的位置信息可以为：基于UTM坐标系的X轴坐标和Y轴坐标。本公开通过使用第一移动设备在二维坐标系的坐标来表示第一移动设备的位置，在可以满足测试轨迹跟踪控制器的准确程度的情况下，有利于简化测试过程中的计算量，从而有利于提高测试的便捷性。
在一个可选示例中，本公开中的定位装置可以包括但不限于：基于RTK(Real-Time Kinematic，实时动态)载波相位差分技术的定位装置。例如，该定位装置包括但不限于：可以与RTK基站进行无线通讯的基于RTK载波相位差分技术的移动站设备(下述简称为RTK移动站设备)。RTK移动站设备包括但不限于：NovAtel移动站设备等。可选的，RTK基站通常设置在RTK移动站设备的附近，RTK基站的架设高度以及架设位置等，可以根据信号传输的实际需求设置。可选的，RTK基站可以架设在高楼顶层或者通讯塔塔顶等固定位置处。RTK基站也可以架设在可移动的设备上。例如，RTK基站可以架设在具有一定高度的车辆(如具有升降装置的车辆等)上。可选的，本公开通过将RTK基站架设在可移动的设备上，可以方便的将RTK基站移动到相应的测试场地中，从而有利于在相应的测试场地实现轨迹跟踪控制器的测试。
需要特别说明的是，RTK基站的架设高度，通常与RTK基站所在环境中的建筑物等信号障碍物的高度相关。可选的，RTK基站的架设高度通常高于其所在环境中的各信号障碍物的高度。在较为空旷的环境中，RTK基站的架设高度可以较低。而在高楼林立的城市道路环境中，RTK基站通常架设在高楼顶层等位置。另外，虽然RTK基站可以架设在可移动的设备上，然而，在轨迹跟踪控制器的测试过程中，RTK基站的位置是固定不动的。
在一个可选示例中，本公开中的第一移动设备上设置的移动站设备可以接收到来自卫星的卫星定位信号(如GPS定位信号或者北斗定位信号等)、以及来自RTK基站的RTK数据。基于卫星定位信号，移动站设备可以获得第一移动设备的粗略位置信息，该粗略位置信息的定位精度通常为米级别。移动站设备根据对接收到的卫星定位信号和RTK数据，可以获得第一移动设备的最终位置信息，该位置信息的位置定位精度可以达到厘米级别。本公开可以采用现有处理方式对卫星定位信号和RTK数据进行处理，以获得第一移动设备的高精度位置信息。例如，基于历元的实时处理等，在此不再详细说明。
可选的，本公开中的第一移动设备上设置的移动站设备的一个例子如图2所示。图2中，移动站设备1可包括：天线11、接收器12以及路由器13。移动站设备1通过天线11与卫星2进行无线信息传输。移动站设备1通过路由器13与RTK基站3进行无线信息传输。RTK基站3可以与卫星2进行无线信息传输。天线11包括但不限于：GPS天线或者北斗天线等。移动站设备1可以通过天线11接收到来自卫星2的卫星定位信号。卫星2包括但不限于：GPS(Global Positioning System，全球定位系统)卫星或者北斗卫星等。卫星定位信号包括但不限于：基于GPS的定位信号或者基于北斗的定位信号等。本公开中的卫星定位信号可以包括但不限于：定位时间(即位置对应的时间)和位置信息。卫星定位信号中的位置信息的定位精度通常为米。移动站设备1可以通过其路由器13接收到来自RTK基站3的RTK数据。RTK数据不仅可以包括：用于描述RTK的信息(下述称为差分数据)，还包括：差分数据对应的时间等。由于差分数据对应的时间来自卫星2，因此，差分数据对应的时间也可以称为定位时间。路由器13包括但不限于：Cellular 4G Router(蜂窝4G路由器)等。接收器12通过对天线11接收到的相应的卫星定位信号中的位置信息和路由器13接收到的相应的RTK数据中的差分数据进行计算，可以获得移动 站设备1的厘米级别的位置信息，从而本公开可以实现对第一移动设备的精准定位。
在一个可选示例中，S100所获得的第一移动设备的定位信息包括但不限于：定位时间以及第一移动设备的位置信息。接收器12可以根据具有相同定位时间的卫星定位信号和RTK数据，获得该定位时间对应的精准定位的位置信息。在不存在具有相同定位时间的卫星定位信号和RTK数据的情况下，接收器12可以根据满足定位时间的时间间隔小于预定时间间隔要求的卫星定位信号和RTK数据，获得卫星定位信号中的定位时间对应的精准定位的位置信息。S100所获得的定位信息中的定位时间可以采用卫星定位信号中的定位时间。
在一个可选示例中，本公开中的第一移动设备的运动状态信息可以包括但不限于：位姿、速度和加速度对应的时间(下述称为速度时间)、速度大小以及加速度大小等。其中的位姿包括但不限于：第一移动设备的偏航角(也可以称为真实世界坐标系中的横摆角，即Yaw)。可选的，第一移动设备的位姿还可以包括：第一移动设备的俯仰角(Pitch)、翻滚角(Roll)以及位姿对应的时间(下述称为位姿时间)等。可选的，本公开可以根据第一移动设备上安装的IMU(Inertial Measurement Unit,惯性测量单元)输出的数据，获得第一移动设备的位姿。在移动站设备集成有IMU的情况下，定位时间可以被作为位姿时间，且本公开可以根据移动站设备输出的信息，获得定位时间、定位时间对应的位置信息以及定位时间对应的偏航角。
在一个可选示例中，在第一移动设备具有提供其速度大小和加速度的能力的情况下，本公开可以从第一移动设备中读取出第一移动设备的速度大小和加速度。例如，本公开可以通过第一移动设备的CAN(Controller Area Network，控制器局域网络)总线，实时地读取出第一移动设备当前时刻的速度大小以及加速度等。其中的加速度的数值可以带正负号，该正负号可以表示出加速度的方向。例如，正号表示加速度的方向与速度的方向相同，负号表示加速度的方向与速度的方向相反。
可选的，S100可以称为原始数据积累阶段。S100所积累的原始数据用于形成多个轨迹点信息。S100所积累的原始数据通常是冗余的，例如，位置信息的密集程度较高，且位置信息可能出现重复。在形成多个轨迹点信息过程中，通常会筛除冗余的信息，从而避免出现轨迹点信息冗余的现象。
可选的，S100所积累的原始数据具体包括的内容，通常是根据待测试轨迹跟踪控制器所需的输入信息设置的。在待测试轨迹跟踪器还需要其他信息的情况下，本公开在原始数据积累阶段，还应该获取其他信息。
可选的，在第一移动设备上设置的惯性测量单元与第一移动设备上设置的定位装置(如移动站设备)相互独立设置的情况下，S100所积累的原始数据可以包括三个数据集合，即定位数据集合、位姿数据集合和速度数据集合。定位数据集合中的数据记录来自设置于第一移动设备上的定位装置。定位数据集合中的任一条数据记录至少包括：定位时间以及精准定位的位置信息。位姿数据集合中的数据记录来自设置于第一移动设备上的惯性测量单元。位姿数据集合中的任一条数据记录至少包括：位姿时间及第一移动设备的偏航角。可选的，位姿数据集合中的任一条数据记录还可以包括：第一移动设备的俯仰角和翻滚角。虽然在下述实施方式中，大多是以位姿具体为偏航角为例进行描述的，然而应该知道，下述描述中的位姿具体为偏航角和俯仰角，或者具体为偏航角和翻滚角，或者具体为偏航角、俯仰角和翻滚角，也是完全可行的。速度数据集合中的数据记录来自第一移动设备自身(如第一移动设备中的CAN总线等)。速度数据集合中的任一条数据记录至少包括：速度时间、速度大小以及加速度等。
可选的，在设置于第一移动设备上的定位装置(如移动站设备)具有测量第一移动设备的位姿功能的情况下，S100所积累的原始数据可包括两个数据集合，即定位和位姿数据集合以及速度数据集合。定位和位姿数据集合中的数据记录来自设置于第一移动设备上的定位装置。定位和位姿数据集合中的任一条数据记录至少包括：定位时间、精准定位的位置信息以及第一移动设备的偏航角。速度数据集合中的数据记录来自第一移动设备自身(如第一移动设备中的CAN总线等)。速度数据集合中的任一条数据记录至少包括：速度时间、速度大小以及加速度(带正负号的加速度数值)等。
S110、根据定位信息和运动状态信息，确定多个轨迹点信息，并形成包括多个轨迹点信息的测试参考轨迹。
在一个可选示例中，本公开所生成的多个轨迹点信息用于形成测试参考轨迹。也就是说，本公开的测试参考轨迹至少包括：多个轨迹点信息。所有轨迹点信息可以认为是一条测试参考轨迹。可选的，本公开中的任一轨迹点信息均可以包括：轨迹点位置信息、轨迹点对应的移动设备的位姿、轨迹点对应的速度大小和速度方向、轨迹点对应的加速度大小和加速度方向。可选的，任一轨迹点信息还可包括：定位时间以及轨迹点对应的轨迹曲率等。可选的，测试参考轨迹可以为一个数据集合，该数据集合包括多条数据记录，每一条数据记录对应一个轨迹点，且一条数据记录即为一个轨迹点信息。
在一个可选示例中，本公开在利用原始数据形成轨迹点信息时，通常需要对原始数据进行冗余处理，以消除原始数据中的重复数据、过于密集的数据等冗余数据，从而有利于提高测试参考轨迹的轨迹点分布的合理性。可选的，本公开可以先根据上述获得的定位信息确定测试参考轨迹的各轨迹点位置信息，然后，再根据上述获得的所有位姿以及运动状态信息，确定各轨迹点的其他信息。
可选的，本公开确定测试参考轨迹的各轨迹点位置信息的过程可以为：根据预先设置的相邻轨迹点间的预定距离，对多个定位信息进行采样处理，从而获得多个轨迹点位置信息。例如，本公开可以先从上述获得的所有定位信息中选取出一个定位信息，并将本次选取出的该定位信息中的位置信息作为测试参考轨迹的起始轨迹点位置信息，然后，本公开可以根据其他定位信息中的位置信息和起始轨迹点位置信息，进行距离计算，并根据距离计算的结果和上述预定距离，从其他定位信息中选取一个与起始轨迹点位置信息的距离和预定距离最相近的定位信息，并将该选取出的定位信息中的位置信息作为起始轨迹点的下一个轨迹点位置信息，以此类推，直到获得测试参考轨迹中的所有轨迹点的位置信息。在获得的所有轨迹点的位置信息中，任意两个相邻的轨迹点之间的距离通常为预定距离或者大约为预定距离。另外，在获得轨迹点的位置信息时，还应获取该位置信息所对应的定位时间。本公开中的预定距离为一常数，预定距离的大小可以根据实际需求设置，例如，预定距离包括但不限于：20厘米等。
本公开通过利用预定距离对定位信息进行采样处理，可以消除数据冗余现象，还可以使轨迹点均匀分布，即可以实现对测试参考轨迹的平滑处理，从而有利于提高测试参考轨迹的合理性。
在一个可选示例中，在移动站设备输出的数据形成定位数据集合的情况下，本公开在确定了测试参考轨迹的各轨迹点位置信息之后，可以根据多个轨迹点位置信息分别对应的定位时间，对多个位姿以及多个运动状态信息分别进行采样处理，从而获得各轨迹点各自对应的位姿以及运动状态信息。例如，针对任一轨迹点而言，本公开可以从位姿数据集合的各数据记录中查找与定位时间最接近的一位姿时间，并将该位姿时间对应的第一移动设备的偏航角作为该轨迹点对应的偏航角。再例如，针对任一轨迹点而言，本公开也可从位姿数据集合的各数据记录中查找与定位时间最接近的至少两个位姿时间，并针对至少两个位姿时间各自对应的第一移动设备的偏航角进行计算(如计算偏航角的均值等)，并将计算结果作为该轨迹点对应的偏航角。
在一些应用场景中(例如，在移动站设备与惯性测量单元相互独立设置的应用场景中)，定位时间与位姿时间通常并不同步，本公开通过以定位时间为基准，对位姿进行采样处理，实现了定位时间与位姿时间的时序对齐，从而有利于快速准确的获得测试参考轨迹。
在一个可选示例中，在移动站设备输出的数据形成定位和位姿数据集合的情况下，本公开在确定测试参考轨迹的各轨迹点位置信息的同时，可以确定各轨迹点对应的偏航角，之后，本公开可以根据多个轨迹点位置信息分别对应的定位时间，对多个运动状态信息分别进行采样处理，从而获得各轨迹点各自对应的位姿以及运动状态信息。例如，针对任一轨迹点而言，本公开可以从速度数据集合的各数据记录中查找与定位时间最接近的一速度时间，并将该速度时间对应的第一移动设备的速度大小和加速度作为该轨迹点对应的速度大小和加速度。再例如，针对任一轨迹点而言，本公开也可以从速度数据集合的各数据记录中查找与定位时间最接近的至少两个位姿时间，并针对至少两个位姿时间各自对应的第一移动设备的偏航角进行计算(如计算偏航角的均值等)，并将计算结果作为该轨迹点对应的偏航角。
在一些应用场景中，定位时间和速度时间通常并不同步，本公开通过以定位时间为基准，对运动状态信息进行采样处理，实现了定位时间与速度时间的时序对齐处理，从而有利于快速准确的获得测试参考轨迹。
在一个可选示例中，针对任一轨迹点而言，本公开可以根据该轨迹点的前后两个轨迹点之间的连线的斜率，确定出该轨迹点对应的速度方向，该速度方向结合加速度数值的正负号，即可以确定加速度方向，例如，加速度方向与速度方向相同或者与速度方向相反。其中的该轨迹点的前后两个轨迹点的连线可以为：位于该轨迹点之前的第n个轨迹点与位于该轨迹点之后的第m个轨迹点的连线。其中的n和m均为大于等于1的整数，且n和m的数值可以相等，n和m的数值不宜过大，如不宜超过4或5等，有利于避免速度方向不准确等现象，从而有利于快速准确的获得测试参考轨迹。
可选的，针对测试参考轨迹中的第i个轨迹点而言，如果将第i个轨迹点之前的第n个轨迹点的位置信息表示为(x i-n,y i-n)，将第i个轨迹点之后的第m个轨迹点的位置信 息表示为(x i+m,y i+m)，则第i个轨迹点的速度方向θ可以通过下述公式(1)表示：
Figure PCTCN2019119889-appb-000001
在上述公式(1)中，Δx表示x i+m与x i-n之间的差值，即Δx＝x i+m-x i-n；Δy表示y i+m与y i-n之间的差值，即Δy＝y i+m-y i-n。
可选的，本公开也可以采用其他方式来获得轨迹点的速度方向，例如，本公开可以将多个轨迹点作为离散点，进行曲线拟合，在获得了相应的曲线方程后，本公开利用该曲线方程，来确定被作为离散点的任一轨迹点的速度方向。
在一个可选示例中，在确定了测试参考轨迹的各轨迹点位置信息以及速度方向之后，还可以确定各轨迹点各自对应的轨迹曲率。可选的，本公开可以根据相邻轨迹点的速度方向的变化量以及相邻轨迹点之间的距离，确定相邻轨迹点中的一轨迹点对应的轨迹曲率。例如，针对任一轨迹点而言，本公开可以利用下述公式(2)表示该轨迹点对应的轨迹曲率k：
Figure PCTCN2019119889-appb-000002
在上述公式(2)中，Δθ表示相邻轨迹点的速度方向的变化量，例如，图3中，轨迹点A的速度方向为θ，轨迹点B的速度方向为θ+Δθ，Δθ即为轨迹点A的速度方向与轨迹点B的速度方向之间的变化量；Δs表示相邻轨迹点之间的距离(如直线距离)，例如，图3中，轨迹点A和轨迹点B之间的距离。
可选的，本公开可以将计算出的轨迹曲率k作为相邻两轨迹点中的前一轨迹点的轨迹曲率(如图3中的轨迹点A对应的轨迹曲率)，也可以将计算出的轨迹曲率k作为相邻两轨迹点中的后一轨迹点的轨迹曲率(如图3中的轨迹点B对应的轨迹曲率)。
可选的，本公开也可以采用其他方式来获得轨迹点的曲率，例如，本公开可以将多个轨迹点作为离散点，进行曲线拟合，在获得了相应的曲线方程后，本公开利用该曲线方程，来确定被作为离散点的任一轨迹点的曲率。
在一个可选示例中，本公开的测试参考轨迹中的多个轨迹点信息，如图4a-图4d所示。图4a中的曲线表示多个轨迹点位置信息在UTM坐标系中所形成的轨迹线。图4a中的横坐标表示UTM坐标系的X轴(单位为米)，纵坐标表示UTM坐标系的Y轴(单位为米)。图4b中的曲线表示多个轨迹点各自对应的速度大小所形成的曲线。图4b的横坐标表示相对于起始轨迹点的距离(单位为米)，纵坐标表示轨迹点对应的速度大小(单位为米/秒)。图4c中的曲线表示多个轨迹点的速度方向所形成的曲线。图4c中的横坐标表示相对于起始轨迹点的距离(单位为米)，纵坐标表示轨迹点对应的速度方向(如上述θ)。图4d中的横坐标表示相对于起始轨迹点的距离(单位为米)，纵坐标表示轨迹点对应的曲率。
本公开形成测试参考轨迹的方式，有利于避免测试参考轨迹的形成需要受到高精地图以及车道线等因素的限制。这样，测试人员可以根据测试需求随时随地的灵活设置出多种形状的测试参考轨迹，而且设置测试参考轨迹的过程不需要考虑天气以及光线等因素。例如，可以在早晨或者中午或者晚间，在乡间小路上设置测试参考轨迹。再例如，可以设置出连续的直角转弯的测试参考轨迹，也可以设置出S形的测试参考轨迹，还可以设置出8字形或者O形或者螺旋形等形状的测试参考轨迹。由此可知，本公开不仅有利于提高测试参考轨迹的地理位置设置范围和时间设置范围，并有利于降低形成测试参考轨迹的实现成本，还有利于提高测试参考轨迹的多样性，另外，还有利于获得待测试轨迹跟踪控制器在多种测试参考轨迹上的性能表现。进一步的，本公开可以根据待测试轨迹跟踪控制器在多种测试参考轨迹上的性能表现，有针对性的调整待测试轨迹跟踪控制器的参数，从而有利于提高轨迹跟踪控 制器的性能。
可选的，本公开中的待测试轨迹跟踪控制器的参数可以为：在待测试轨迹跟踪控制器根据输入信息形成自动行驶控制指令过程中，所使用到的参数。本公开提供的测试方法可适用于自动驾驶中各种架构的轨迹跟踪控制器，基于测试结果进行控制器参数的优化调整，例如，可适用但不限于PID(比例P-积分I-微分D)三相架构的轨迹跟踪控制器，调整三相参数；又例如，可适用但不限于MPC(Model Predictive Control，模型预测控制)架构轨迹跟踪控制器，调整与误差、控制指令相关的闭环优化控制参数；由此提高轨迹跟踪控制器的控制性能。
S120、根据测试参考轨迹的至少部分轨迹点信息为待测试轨迹跟踪控制器提供输入信息。
在一个可选示例中，本公开中的待测试轨迹跟踪控制器设置于第二移动设备中。由于待测试轨迹跟踪控制器设置在第二移动设备中，因此，相对于现有的利用模拟器对轨迹跟踪控制器进行测试的方式而言，本公开有利于避免模拟器测试环境与真实环境之间的差异而导致的测试结果不准确的现象，进而可以避免轨迹跟踪控制器被布置在实际的移动设备中时，需要进一步调试而导致的浪费时间成本和人力成本的现象。
在一些应用场景中，第二移动设备与S100中的第一移动设备可以为同一个移动设备。如一车辆中安装有轨迹跟踪控制器，本公开需要对该车辆中的轨迹跟踪控制器进行测试，即该车辆中的轨迹跟踪控制器为待测试轨迹跟踪控制器。本公开可以先请驾驶员驾驶该车辆按照预定路线(例如，S形路线或者8字形路线或者O形路线或者螺旋形路线等)进行行驶，此时该车辆被作为第一移动设备。本公开可以在该车辆行驶过程中持续收集并存储原始数据(如S100所记载的方法)。本公开可以在该车辆行驶过程中或者在该车辆行驶结束后，利用上述S110所记载的方法对收集并存储的原始数据进行处理，从而生成多个轨迹点信息，所有轨迹点信息形成了测试参考轨迹。之后，该车辆被设置在预定路线上的任一位置(如预定路线的起点)或者预定路线附近(如预定路线的起点附近)，使该车辆处于受控于待测试轨迹跟踪控制器的行驶状态，即该车辆处于自动驾驶模式，该车辆被作为第二移动设备。
在一些应用场景中，第二移动设备也可以为与S100中的第一移动设备不同的移动设备。如一车辆中安装有轨迹跟踪控制器，本公开需要对该车辆中的轨迹跟踪控制器进行测试，即该车辆中的轨迹跟踪控制器为待测试轨迹跟踪控制器。本公开可以先请驾驶员驾驶另一车辆按照预定路线(如S形路线或者8字形路线或者O形路线或者螺旋形路线等)进行行驶，此时该另一车辆被作为第一移动设备。该另一车辆中可以安装有轨迹跟踪控制器，也可以未安装有轨迹跟踪控制器。本公开可以在该另一车辆行驶过程中持续收集并存储原始数据。本公开可以在该另一车辆行驶过程中或者在该另一车辆行驶结束后，利用上述S110所记载的方法对收集并存储的原始数据进行处理，从而生成多个轨迹点信息，所有轨迹点信息形成了测试参考轨迹。之后，安装有待测试轨迹跟踪控制器的车辆被设置在预定路线上的任一位置(如预定路线的起点)或者预定路线附近(如预定路线的起点附近)，使装有待测试轨迹跟踪控制器的车辆处于受控于待测试轨迹跟踪控制器的行驶状态，即装有待测试轨迹跟踪控制器的车辆处于自动驾驶模式，从而装有待测试轨迹跟踪控制器的车辆被作为第二移动设备。
可选的，在第一移动设备和第二移动设备为两个不同的移动设备的情况下，本公开中的第二移动设备上同样设置有定位装置，以便于通过定位装置来接收定位信号(如卫星定位信号等)，这样，本公开可以通过该定位装置接收到的定位信号，来获得第二移动设备的定位信息。同样的，第二移动设备的定位信息包括但不限于：定位时间(如定位时间戳)以及第二移动设备的位置信息。第二移动设备的位置信息包括但不限于：第二移动设备在真实世界坐标系(如UTM坐标系)中的坐标。可选的，第二移动设备上设置的定位装置可以包括但不限于：基于RTK载波相位差分技术的定位装置。第二移动设备上安装的该定位装置可以与第一移动设备上安装的定位装置相同。在此不再重复描述。
在一个可选示例中，本公开可以实时的根据第二移动设备的位置，从测试参考轨迹中截取一部分轨迹(也可以称为一段轨迹)，截取出的这一部分轨迹可以称为子测试参考轨迹。本公开可以根据实时获得的子测试参考轨迹所包含的轨迹点信息，为待测试轨迹跟踪控制器提供相应的输入信息。可选的，本公开在每次获得子测试参考轨迹时，根据该子测试参考轨迹中的轨迹点信息为待测试轨迹跟踪控制器提供一次输入信息。
本公开通过根据第二移动设备的位置来截取出子测试参考轨迹，并利用子测试参考轨迹为待测试轨迹跟踪控制器提供输入信息，有利于保证为待测试轨迹跟踪控制器提供恰当的输入信息，从而有利于使受控于待测试轨迹跟踪控制器的第二移动设备跟踪测试参考轨迹行驶。
在一个可选示例中，本公开根据轨迹点信息，为待测试轨迹跟踪控制器提供输入信息的实现过程可以包括如下步骤：
步骤1、获取设置有待测试轨迹跟踪控制器的第二移动设备的当前位置信息。
可选的，本公开可以根据预定频率(例如，100赫兹等)，实时地获取设置有待测试轨迹跟踪控制器的第二移动设备的当前位置信息，即本公开每隔一定时间(如0.01秒)获取一次第二移动设备的当前位置信息。例如，在第二移动设备在测试参考轨迹的起点位置就绪后，本公开会根据预定频率，实时地从第二移动设备中设置的移动站设备处，获取第二移动设备的当前位置信息。
可选的，本公开所获取到的第二移动设备的当前位置信息可以为厘米级别的位置信息，这样，本公开可以实现对第二移动设备的精准定位，从而有利于提高截取出的子测试参考轨迹的准确性，进而有利于提高轨迹跟踪控制器的测试准确性。
步骤2、根据当前位置信息以及轨迹点信息，确定测试参考轨迹中与当前位置信息距离最近的轨迹点。
可选的，本公开可以获取所有位于第二移动设备未行驶过的测试参考轨迹中的轨迹点的位置信息(如基于UTM坐标系的X坐标和Y坐标)，并根据获取到的各位置信息和第二移动设备的当前位置信息(如基于UTM坐标系的X坐标和Y坐标)，计算当前第二移动设备与各轨迹点之间的距离，并从中选取距离最近的轨迹点。其中的未行驶过的测试参考轨迹是指，位于第二移动设备的行驶前方且等待第二移动设备行驶的测试参考轨迹。在一些应用场景中，第二移动设备可能会出现偏离测试参考轨迹行驶的现象，测试参考轨迹中的被偏离的部分通常不属于未行驶过的测试参考轨迹。
步骤3、根据距离最近的轨迹点，从测试参考轨迹中截取子测试参考轨迹。
可选的，在确定出距离最近的轨迹点的情况下，本公开可以直接以距离最近的轨迹点为依据，从测试参考轨迹上截取子测试参考轨迹。本公开也可以对该距离最近的轨迹点进行判断，并根据判断结果来决定是否需要以距离最近的轨迹点为依据，从测试参考轨迹上截取子测试参考轨迹。例如，判断该距离最近的轨迹点与当前位置信息之间的距离是否满足预定距离要求(如是否小于k米，k为非零的正整数，如k＝4或4.5或5米等)。如果判断的结果为满足预定距离要求(如小于k米)，则本公开以距离最近的轨迹点为依据，从测试参考轨迹上截取子测试参考轨迹，如以距离最近的轨迹点为第1个轨迹点，截取出j(j为预设常数值，如j大于30或35或40等)个轨迹点。如果判断的结果不满足预定距离要求(如不小于k米)，则本公开可以不执行子测试参考轨迹的截取操作，从而本次不会为待测试轨迹跟踪控制器提供输入信息。
本公开通过针对距离最近的轨迹点与当前位置信息进行是否满足预定距离要求的判断，有利于避免在第二移动设备与距离最近的轨迹点相距较远的情况下，出现的转向角度过大(如方向盘转向剧烈等)而引发的潜在安全隐患等现象。
可选的，针对一个待测试轨迹跟踪控制器而言，在测试的过程中，在第二移动设备持续移动的情况下，每次从测试参考轨迹中截取出的子测试参考轨迹通常并不相同。针对任意两个不同待测试轨迹跟踪控制器而言，其中一个测试过程所截取出的所有子测试参考轨迹，与另一个测试过程所截取出的所有子测试参考轨迹，通常并不相同。因此，本公开中的子测试参考轨迹可以称为局部测试参考轨迹。
相应的，针对任意两个不同待测试轨迹跟踪控制器而言，其中一个待测试轨迹跟踪控制器的测试过程所使用的测试参考轨迹，与另一个测试过程所使用的测试参考轨迹通常相同，本公开所形成的测试参考轨迹面向多个待测试轨迹跟踪控制器，即多个待测试轨迹跟踪控制器均基于该测试参考轨迹实现测试。因此，本公开所形成的测试参考轨迹可以称为全局测试参考轨迹，可适用不同的轨迹跟踪控制器进行测试。
步骤4、根据子测试参考轨迹中的轨迹点信息，为待测试轨迹跟踪控制器提供输入信息。
可选的，本公开中的子测试参考轨迹通常包括多个轨迹点。本公开可以从子测试参考轨迹中选取一个轨迹点，并根据选取出的轨迹点的轨迹点信息，为待测试轨迹跟踪控制器提供输入信息。例如，从子测试参考轨迹的中间段或者中后段中选取一个轨迹点(如选取子测试参考轨迹中的第25或者第30个轨迹点)，并根据该轨迹点信息，为待测试轨迹跟踪控制器提供输入信息。本公开也可以从子测试参考轨迹中选取多个轨迹点，并针对选取出的多个轨迹点的轨迹点信息进行计算(如基于权值的计算等)，从而根据计算的结果，为待测试轨迹跟踪控制器提供输入信息。例如，从子测试参考轨迹的中间段或者中后段中选取出连续的多个轨迹点，并根据选取出的多个轨迹点各自对应的权值，针对上述多个轨迹点的轨迹点信息进行计算，从而根据计算的结果，为待测试轨迹跟踪控制器提供输入信息。各轨迹点对应的权值可以不相同，也可以相同(即进行均值计算)。在各轨迹点对应的权值不相同的情况下，各轨迹点对应的权值的大小可以根据各轨迹点与第二移动设备之间的距离大小来设置。例如，距离第二移动设备近的轨迹点所对应的权值大于距离第二移动设备远的轨迹点所对应的权值。
可选的，本公开在为待测试轨迹跟踪控制器提供输入信息时，需要进行从基于全局的信息到基于局部的信息的映射处理，以获得待测试轨迹跟踪控制器所需的基于局部的信息。例如，首先将全局测 试参考轨迹中的轨迹点信息中的位置信息、速度方向以及加速度方向，分别转换为基于第二移动设备坐标系的位置信息、速度方向以及加速度方向；然后，将速度大小、加速度大小以及转换后的位置信息、速度方向和加速度方向作为输入信息，提供给第二移动设备中设置的待测试轨迹跟踪控制器。另外，本公开还可以对偏航角以及轨迹点的曲率等信息也进行从基于全局的信息到基于局部的信息的映射处理，并将映射处理后的偏航角以及曲率等信息也作为输入信息，提供给第二移动设备中设置的待测试轨迹跟踪控制器。
可选的，假定全局测试参考轨迹中的轨迹点信息中的位置信息的坐标系(如UTM坐标系)，与基于第二移动设备坐标系之间的旋转矩阵为R，平移矩阵为p，则本公开可以利用下述公式(3)将全局测试参考轨迹中的轨迹点信息中的位置信息转换为基于第二移动设备坐标系的位置信息：
Figure PCTCN2019119889-appb-000003
在上述公式(3)中，P v表示基于第二移动设备坐标系的轨迹点位置信息；P w表示全局测试参考轨迹中的轨迹点信息中的位置信息；
Figure PCTCN2019119889-appb-000004
表示
Figure PCTCN2019119889-appb-000005
的逆矩阵，且
Figure PCTCN2019119889-appb-000006
R表示旋转矩阵，为预先设置的已知值；p表示平移矩阵，为预先设置的已知值。
可选的，本公开可以利用下述公式(4)将全局测试参考轨迹中的轨迹点信息中的速度方向转换为基于第二移动设备坐标系的速度方向：
V v＝R TV w               公式(4)
在上述公式(4)中，V v表示基于第二移动设备坐标系的速度方向；V w表示全局测试参考轨迹中的轨迹点信息中的速度方向；R T表示旋转矩阵R的转置矩阵。
可选的，待测试跟踪控制器可以将接收到的轨迹点的速度大小、加速度大小以及转换后的位置信息、速度方向和加速度方向作为目标信息，结合第二移动设备的当前位置信息、当前速度以及当前加速度等信息，输出相应的自动行驶控制指令，自动行驶控制指令可以通过CAN总线等提供给第二移动设备中的相应部件。
可选的，在第二移动设备为车辆的情况下，本公开中的自动行驶控制指令包括但不限于：方向盘转角控制量、油门控制量以及刹车控制量中的至少一个。车辆中的相应部件根据接收到的自动行驶控制指令，执行相应的操作，从而使车辆实现自动驾驶。在第二移动设备为机器臂或者机器人等的情况下，本公开中的自动行驶控制指令包括但不限于：机器人或者机器臂的转向控制量以及行动频率控制量中的至少一个。自动行驶控制指令具体包括的内容可以根据实际需求设置，本公开对此不作限制。
S130、获取第二移动设备根据自动行驶控制指令行驶的行驶信息。
在一个可选示例中，本公开中的行驶信息可以包括：第二移动设备的实际移动轨迹、第二移动设备的实际速度大小和方向、实际加速度大小和方向、实际位姿以及第二移动设备的实际移动轨迹的曲率等中的至少一个。
可选的，本公开可以根据第二移动设备上设置的定位装置实时获得第二移动设备的定位时间、位置信息以及位姿(如第二移动设备的实际偏航角)，从而可以获得第二移动设备的实际移动轨迹以及在实际移动轨迹上的不同位置处的实际位姿。本公开可以实时的从第二移动设备中读取出第二移动设备的速度时间(即速度时间戳)、速度大小以及加速度(包括加速度大小和加速度方向)。例如，通过第二移动设备的CAN总线实时读取出第二移动设备的速度时间、速度大小以及加速度。本公开可以利用上述S110所示的方法获得第二移动设备的多个实际轨迹点信息。多个实际轨迹点信息形成第二移动设备的实际移动轨迹。相邻的两个实际轨迹点之间的距离可以与测试参考轨迹中的相邻的两个轨迹点之间的距离相同。获得实际轨迹点信息的具体过程在此不再重复说明。
可选的，本公开可以对比第二移动设备的实际移动轨迹中的实际轨迹点信息与测试参考轨迹中的 轨迹点信息，获取并输出对比所形成的差异，该差异可以反映出轨迹跟踪控制器的性能。本公开可以利用可视化的形式显示对比所形成的差异。如可以在第二移动设备的行驶过程中，在线可视化显示。再例如，可以在第二移动设备行驶完成后，离线可视化显示或形成性能分析报告。
可选的，本公开可以在第二移动设备的行驶过程中，实时的显示全局测试参考轨迹、第二移动设备当前位置以及第二移动设备的历史实际移动轨迹，如图5中，8字形路线即全局测试参考轨迹，长方形表示第二移动设备。长方形所在的位置为第二移动设备的当前位置。第二移动设备从图5的右下方开始行驶，其历史实际移动轨迹的部分轨迹并未与测试参考轨迹完全吻合。第二移动设备当前获得的子测试参考轨迹如图5中的白色曲线部分。随着第二移动设备的移动，本公开可以实时地从8字形路线中截取出需要第二移动设备循轨迹移动的子测试参考轨迹，来替换当前显示的子测试参考轨迹。在截取需要第二移动设备循轨迹移动的子测试参考轨迹时，可以依据第二移动设备的当前位置进行截取。由上述描述可知，本公开可以直观清晰地展现出第二移动设备循轨迹移动的情况。
在一个可选示例中，本公开的可视化显示对比所形成的差异的一个例子如图6所示。图6中的左上图中存在两条曲线，其中一条曲线表示多个轨迹点位置信息在UTM坐标系中所形成的测试参考轨迹，其中另一条曲线表示第二移动设备循测试参考轨迹移动所形成的实际轨迹点位置信息在UTM坐标系中所形成的实际轨迹。由于两条轨迹完全重合，因此，图6的左上图中只显示出了一条曲线。左上图中的横坐标表示UTM坐标系的X轴(单位为米)，纵坐标表示UTM坐标系的Y轴(单位为米)。图6中的右上图中存在两条曲线，其中一条曲线是由测试参考轨迹中的多个轨迹点各自对应的速度大小形成的，其中另一条曲线是由第二移动设备的实际轨迹中的多个实际轨迹点各自对应的速度大小形成的。右上图中的横坐标表示相对于起始轨迹点的距离(单位为米)，纵坐标表示速度大小(单位为米/秒)。图6中的左下图中存在两条曲线，其中一条曲线是由测试参考轨迹中的多个轨迹点的速度方向而形成的，另一条曲线是由第二移动设备的实际轨迹中的多个实际轨迹点各自对应的速度方向形成的。图6中的左下图中的横坐标表示相对于起始轨迹点的距离(单位为米)，纵坐标表示速度方向(如上述θ)。图6中的右下图包括两条曲线，其中一条曲线是由测试参考轨迹中的多个轨迹点各自对应的曲率形成的，其中另一条曲线是由第二移动设备的实际轨迹中的多个实际轨迹点各自对应的曲率形成的；右下图中的横坐标表示相对于起始轨迹点的距离(单位为米)，纵坐标表示曲率。轨迹跟踪控制器向第二移动设备发送如油门、刹车、方向盘转角等控制指令控制第二移动设备按照测试参考轨迹行驶，行驶过程中如速度大小、速度方向、曲率等信息和测试参考轨迹形成所依据的第一移动设备的相应轨迹点信息中包括的速度大小、速度方向、曲率等信息之间的差异，从图中可见，可直观体现轨迹跟踪控制器的控制与第一移动设备的驾驶员控制或其他控制器控制之间的差异或接近程度，进而可直观显示或测试评估轨迹跟踪控制器的性能。
可选的，本公开可视化显示对比所形成的差异的另一个例子如图7所示。
图7中的上中下三个图的横坐标均为时间(单位为秒)。图7上图中的曲线表示随着时间的变化，第二移动设备在偏航角上的误差，即测试参考轨迹中的轨迹点的偏航角与实际轨迹中的相应轨迹点的偏航角的差值。图7上图的纵坐标的单位为米。图7中图中的曲线表示随着时间的变化，第二移动设备在速度方向上的误差，即测试参考轨迹中的轨迹点的速度方向与实际轨迹中的相应轨迹点的速度方向的差值。图7中图的纵坐标为角度(单位为度)。图7下图中的曲线表示随着时间的变化，第二移动设备在速度大小上的误差，即测试参考轨迹中的轨迹点的速度大小与实际轨迹中的相应轨迹点的速度大小的差值。图7下图纵坐标的单位为速度(单位为米/秒)。轨迹跟踪控制器向第二移动设备发送油门、刹车或方向盘转角等控制指令控制第二移动设备按照测试参考轨迹行驶，行驶过程中如偏航角、速度大小、速度方向等信息，和测试参考轨迹形成所依据的第一移动设备的相应轨迹点信息中包括的偏航角、速度大小、速度方向等信息之间的差异，从图可见，可直观体现轨迹跟踪控制器的控制与第一移动设备的驾驶员控制或其他控制器控制之间的差异或接近程度，进而可直观显示或测试评估轨迹跟踪控制器的性能。
图8为本公开的轨迹跟踪控制器的测试装置一个实施例的结构示意图。图8所示的装置包括：第一获取模块800、第一生成模块810、提供输入模块820以及第二获取模块830。可选的，轨迹跟踪控制器的测试装置还可以包括：形成差异模块840、显示模块850以及调整参数模块860中的至少一个。下面对各模块分别进行详细描述。

可选的，提供输入模块820可以包括：第五子模块、第六子模块、第七子模块以及第八子模块。其中的第五子模块用于获取待测试轨迹跟踪控制器所在的第二移动设备的当前位置信息。其中的第六子模块用于根据当前位置信息以及轨迹点信息，确定测试参考轨迹中与当前位置信息距离最近的轨迹点。其中的第七子模块用于根据距离最近的轨迹点，从测试参考轨迹中截取子测试参考轨迹。例如，在确定出距离最近的轨迹点的情况下，第七子模块可以直接以距离最近的轨迹点为依据，从测试参考轨迹上截取子测试参考轨迹。第七子模块也可以对该距离最近的轨迹点进行判断，并根据判断结果来决定是否需要以距离最近的轨迹点为依据，从测试参考轨迹上截取子测试参考轨迹。例如，第七子模块判断该距离最近的轨迹点与当前位置信息之间的距离是否满足预定距离要求。如果判断的结果为满足预定距离要求，则第七子模块以距离最近的轨迹点为依据，从测试参考轨迹上截取子测试参考轨迹。如果判断的结果不满足预定距离要求，则第七子模块可以不执行子测试参考轨迹的截取操作，从而本次第八子模块不会为待测试轨迹跟踪控制器提供输入信息。其中的第八子模块用于根据子测试参考轨迹中的轨迹点信息，为待测试轨迹跟踪控制器提供输入信息。例如，第八子模块从子测试参考轨迹中选取一个轨迹点，根据选取出的轨迹点的轨迹点信息，确定待测试轨迹跟踪控制器的输入信息。再例如，第八子模块从子测试参考轨迹中选取多个轨迹点，针对选取出的多个轨迹点的轨迹点信息进行综合处理，并根据综合处理结果，确定待测试轨迹跟踪控制器的输入信息。可选的，第八子模块可以将轨迹点信息中的位置信息、速度方向以及加速度方向，分别转换为第二移动设备坐标系中的位置信息、速度方向以及加速度方向。第八子模块还可以将速度大小、加速度大小以及转换后的位置信息、速度方向和加速度方向提供给待测试轨迹跟踪控制器。
