由于在切换到真实超声波雷达后,会受到噪声影响,真实超声波雷达的检测信息与超声波雷达模型产生的虚拟检测信号并不完全一致,导致车辆无法正确处理真实超声波雷达信息,出现大量问题。
下面参考附图描述本公开实施例的超声波雷达控车策略的测试方法、装置、***和存储介质。
图1为根据本公开实施例提供的一种超声波雷达控车策略的测试方法的流程图。参考图1所示,该测试方法包括以下步骤:
在S101中,获取超声波雷达的检测信息,该超声波雷达设置在待测车辆上。
也即是,通过真实的超声波雷达进行检测。
在S102中,基于待测车辆的车辆模型和待测车辆所处环境的环境模型,获取待测车辆的整车信息。
其中,车辆模型根据待测车辆的实际车况进行搭建。环境模型为映射现实场景的环境,环境模型中的道路及车辆行驶域需要与现实场景达到一致。
在S103中,根据检测信息和整车信息按照控车策略控制车辆模型动作,以得到控车结果。
其中,控车结果用于对控车策略进行分析。
在本公开实施例中,采用设置在待测车辆上的超声波雷达来获取检测信息,并根据检测信息来对控车策略进行测试,解决了噪点难以添加的问题,降低了真实车辆不可预知因素对控车的影响。
此外,基于搭建的车辆模型、环境模型以及真实超声波雷达获取的检测信息进行超声波雷达控车策略的测试,降低了研发成本,缩短了研发周期。
图2为根据本公开实施例提供的另一种超声波雷达控车策略的测试方法的流程图。参考 图2所示,该测试方法可以由测试设备执行。该测试方法包括以下步骤:
在S201中,获取超声波雷达的检测信息,该超声波雷达设置在待测车辆上。
本公开实施例中,采用真实超声波雷达对待测车辆信息进行检测。示例性地,可将超声波雷达通过粘合支架直接粘贴在未改制的待测车辆上。该设置方式实现简单,且成本低。
示例性地,在将超声波雷达设置在待测车辆上之后,可以对超声波雷达进行测试标定,在测试标定后,对待测车辆信息(即待测车辆周围的障碍物信息)进行检测,然后通过CAN(Controller Area Network,控制器局域网络)输出接口(即CAN接口)对外发送检测到的信息。这里,对外是指对超声波雷达之外的设备发送检测信息。
需要说明的是,本公开实施例对待测车辆的类型不做限制,只要能够承载超声波雷达即可。
在S202中,搭建待测车辆的车辆模型和环境模型,其中,车辆模型根据待测车辆的实际车况进行搭建。
在本公开实施例中,车辆模型和环境模型可分别采用上位机中的仿真软件进行搭建。
示例性地,可通过仿真软件根据待测车辆搭建理想车辆动力学模型作为控制执行机构,并可通过仿真软件搭建环境模型。
在本公开实施例中,环境模型用于映射现实场景的环境(即用于映射待测车辆所处的环境),环境模型中的道路及车辆行驶域需要与现实场景达到一致。作为一个示例,环境模型包括一条车道、车道中轴线和停车区域,其中,停车区域可以车道中轴线为位置参考线向车道两边各延伸一定距离(如10m)的区域。
需要说明的是,S202为可选步骤,车辆模型和环境模型可以预先搭建,需要使用的时候,直接调用即可。
在S203中,基于车辆模型,获取待测车辆处于环境模型对应的环境时的整车信息。
示例性地,整车信息包括但不限于车辆的行驶状态信息以及位置信息。该行驶状态信息包括但不限于整车速度、转向角、转向速度、油门位置和档位等,该位置信息可以为相对环境模型中的参照物的位置信息,例如相对于车位的位置以及偏航角等。
该整车信息用以控制车辆整体状态泊进停车位置;获取当前转向、制动、油门、档位,作为执行对象,车辆获得相应速度、转向、转向角等目标值。
通过S202-S203可实现基于所述待测车辆的车辆模型和所述待测车辆所处环境的环境模型,获取所述待测车辆的整车信息。
在S204中,根据整车信息和超声波雷达的检测信息对待测车辆的ECU(Electronic Control Unit,电子控制单元)的功能进行测试,以生成控制决策信息。
在本公开实施例中,ECU的功能包括但不限于APA(Auto Parking Assist,自动泊车)、BSD(Blind Spot Detection,盲区监测)、FCW(Forward Collision Warning)前方碰撞预 警等功能。ECU的功能即控车策略。
控制决策信息包括但不限于速度、转向方向、转向角等目标值。

可替代地,也可通过ECU控制器根据从下位机获取的整车信息和超声波雷达的检测信息对待测车辆的ECU功能进行测试以生成控制决策信息。
在S205中,将控制决策信息发送给车辆模型进行执行,以便根据执行结果对ECU功能进行分析。
通过该步骤S205即可实现根据控制决策信息控制车辆模型动作,该车辆模型的执行结果即控车结果。在本公开实施例中,控车结果包括转向速度、转向角、行驶速度、行驶距离、最终停靠位置和车辆偏航角等。
通过S204和S205,即可实现根据所述检测信息和所述整车信息按照控车策略控制所述车辆模型动作,以得到控车结果。
示例性地,可将控制决策信息发送给环境模型中的车辆模型进行执行,从而根据车辆模型的执行结果对ECU控制算法和ECU控制器的功能实现的完成度和有效性进行分析。
下面以APA功能为例,对本公开实施例的测试方法进行示例性说明。APA的执行过程通常包含寻找车位过程、泊车入位过程、前向距离及位姿调控过程。
在泊车过程中,获取整车信息及超声波雷达的检测信息,输入给ECU控制器或者虚拟ECU;ECU控制器或者虚拟ECU生成控制决策信息;根据控制决策信息控制环境模型中的车辆模型进行泊车,最终停靠在环境模型中的车位中(为加速测试,现实场景中不做泊车,即待车车辆不动作);根据最终车辆模型位姿(偏航角是否与车位同方向、前后车距是否达到要求),及泊车过程中车辆信息的变化,衡量功能算法是否满足功能要求,即衡量控车策略是否满足要求。
对于APA功能,衡量控车策略的完成度和有效性包括是否顺滑完成整个泊车过程,是否出现频繁档位切换或者转向的情况,最终泊车前后间距是否满足指标要求、位姿方向是否跟车位方向一致等。如果这些条件均达到要求,表示APA功能合格。
