具体实施方式
这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本说明书相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本说明书的一些方面相一致的装置和方法的例子。

接下来对本说明书实施例进行详细说明。
在一些实施方式中,道路清扫工作的高危险、高强度与高重复性等特性使得无人驾驶技术在此方面有广阔的应用前景。如图1所示,在无人驾驶车辆101在进入路口时,无人驾驶车辆101上的车载终端102基于路口内的交通参与者103当前所处的位置,控制无人驾驶车辆101行驶,以与处于路口内的交通参与者103进行交互。但在控制无人驾驶车辆101行驶时,是将交通参与者103作为静态对象,容易出现无法及时与移动的交通参与者103交互的问题,导致无人驾驶车辆无法安全地通过路口。
因此,针对上述问题,本申请实施例提出了一种交互方法,该方法通过在无人驾驶车辆需通过路口时,车载终端基于无人驾驶车辆的行驶方向确定无人驾驶车辆通过路口时所关注的路口区域以及车道区域,根据路口区域以及车道区域内的交通参与者的行驶状态信息,确定交通参与者对应的路权,并预测交通参与者的行驶轨迹,从而利用该行驶轨迹确定出与无人驾驶车辆存在交互的交通参与者,即确定出交互参与者。根据该交互参与者对应的路权控制无人驾驶车辆停止行驶或低速行驶,以及时避让相应的交通参与者,实现与交通参与者的及时交互,使得无人驾驶车辆可以安全通过路口,保证无人驾驶车辆的行驶安全性。
如图2所示,图2是本说明书根据一示例性实施例示出的一种车辆行驶方法的流程图,包括以下步骤:步骤201、获取车辆的待通过路口区域内的第一交通参与者的第一行驶状态信息和目标行驶车道,并获取车辆的第二行驶状态信息。其中,第一行驶状态信息包括第一交通参与者的当前位置。第二行驶状态信息包括车辆的当前位置和行驶方向。
在本实施例中,当车辆需通过路口时,将该路口作为待通过路口,采集包括该待通过路口的图像,对该图像进行识别,以确定该待通过路口区域以及待通过路口区域内的交通参与者,将该待通过路口区域内的交通参与者作为第一交通参与者。确定各个第一交通参与者的行驶状态信息,即第一行驶状态信息,以及确定各个第一交通参与者的目标行驶车道。获取车辆的行驶状态信息,并将其确定为第二行驶状态信息。
可选的,当车辆进入引导车道,即进入包含导向车道线的车道区域时,采集包括待通过路口的图像。具体的,车辆可以在行驶至距离引导车道内的停止线的一定距离内,进行拍摄。
其中,第一交通参与者为可移动的对象,例如,车辆。第一交通参与者的第一行驶状态信息包括第一交通参与者的当前位置、第一交通参与者的当前行驶速度、第一交通参与者的当前朝向和第一交通参与者上的预设点的当前位置中的一个或多个。当第一交通参与者为车辆时,第一交通参与者的当前朝向可以是当前车辆朝向,具体的,其可以 为车辆当前的朝向角;第一交通参与者上的预设点的当前位置可以是车辆上的一个预设点,例如,预设点车辆头部上的一个点(如图3中所示的预设点)。
其中,第一交通参与者的目标行驶车道表示预测的第一交通参与者待行驶的车道,即第一交通参与者欲驶入的车道。
其中,车辆的第二行驶状态信息包括车辆的当前位置、当前行驶速度和行驶方向中的一个或多个。该行驶方向包括直行、左转、右转等方向。
可选的,车辆为可以进行自动驾驶的车辆,例如,无人驾驶车辆。
步骤202、根据第一交通参与者的第一行驶状态信息、目标行驶车道和车辆的第二行驶状态信息,确定第一交通参与者对应的路权信息。其中,路权信息指示车辆对于第一交通参与者待采取的避让行为。
在本实施例中,基于第一交通参与者的第一行驶状态信息和目标行驶车辆可以预测第一交通参与者的行驶轨迹。根据车辆自身的第二行驶状态信息(即车辆的当前位置和行驶方向)以及第一交通参与者的行驶轨迹,判定车辆与第一交通参与者之间的避让情况,以确定第一交通参与者对应的路权信息。
可选的,路权信息包括第一路权和第二路权。其中,第一路权表示高路权,其指示车辆进行避让,即当第一交通参与者的路权信息为第一路权时,车辆需避让该第一交通参与者。第二路权表示低路权,其指示车辆不进行避让,即当第一交通参与者的路权为第二路权时,车辆无需避让该第一交通参与者。
可选的,路权信息还可以包括第三路权。该第三路权表示第一交通参与者对车辆不存在影响,即与车辆无关。当第一交通参与者的路权信息为第三路权时,车辆无需与该第一交通参与者进行交互。
步骤203、从第一交通参与者中确定交互参与者。其中,交互参与者指示参与车辆的行驶信息的决策的目标对象。
在本实施例中,在确定第一交通参与者后,从第一交通参与者中筛选出车辆需进行交互的第一交通参与者,即确定出参与车辆的行驶信息的决策的第一交通参与者,并将筛选的第一交通参与者作为交互参与者。
步骤204、根据交互参与者对应的路权信息控制车辆行驶。
在本实施例中,在确定交互参与者后,从第一交通参与者的路权信息中确定交互参与者对应的路权信息,以供根据该交互参与者的路权信息确定车辆的路口通行策略,并根据该路口通行策略控制车辆进行行驶,使得车辆在通过待通过路口区域的过程中,可以及时与交互参与者进行交互(例如,车辆等待交互参与者通过路口才进行行驶,即避让相应的交互参与者),保证交互的及时性。
在本实施例中,从待通过路口区域内的第一交通参与者中筛选出影响车辆行驶的交互参与者,并基于预测的该交互参与者对应的行驶轨迹控制车辆行驶,而不是将交通参与者作为静态对象,使得车辆可以及时与交互参与者进行交互(例如,避让交互参与者),保证车辆可以安全低通过待通过路口。
从上述描述可知,根据车辆的待通过路口区域内的交通参与者,即第一交通参与者的当前位置和目标行驶车道(即预测的第一交通参与者待行驶的车道)以及车辆的当前位置和行驶方向确定车辆对于第一交通参与者待采取的避让行为,即根据第一交通参与者的预测行驶情况以及车辆的当前行驶情况确定车辆与第一交通参与者之间的避让情况,以得到第一交通参与者对应的路权信息。从第一交通参与者中确定出参与车辆的行驶信息的决策的交互参与者,即确定出与车辆存在交互的第一交通参与者,并根据交互参与者的路权信息控制车辆行驶通过该待通过路口区域,使得车辆在通过待通过路口区域的过程中,可以及时避让相应的交互参与者,实现车辆与交通参与者的及时交互,提高车辆行驶的安全性。
如图4所示,图4是本说明书根据一示例性实施例示出的另一种车辆行驶方法的流 程图,在从第一交通参与者中确定交互参与者时,可以利用第一交通参与者的期望状态信息进行确定。下面将结合一个具体实施例对此过程进行详细说明,如图4所示,该方法包括以下步骤:
步骤401、获取车辆的待通过路口区域内的第一交通参与者的第一行驶状态信息和目标行驶车道,并获取车辆的第二行驶状态信息。其中,第一行驶状态信息包括第一交通参与者的当前位置。第二行驶状态信息包括车辆的当前位置和行驶方向。
在本实施例中,由于车辆在通过待通过路口区域的过程中,也会受到其它车道区域内的交通参与者的影响,因此,为了进一步提高车辆通过待通过路口区域的安全性,还可以确定影响车辆通行的车道区域内的第一交通参与者,以从该车道区域内的第一交通参与者和待通过路口区域内的第一交通参与者中筛选出交互参与者,并根据该交互参与者对应的路权信息控制车辆进行行驶。
可选的,确定影响车辆通行的车道区域内的第一交通参与者的具体过程包括:获取目标车道区域。其中,目标车道区域包括至少一个车道,目标车道区域指示车辆通过待通过路口区域时所关注的车道区域。对于目标车道区域内的每个车道,获取车道内的各个第二交通参与者对应的碰撞时间。其中,碰撞时间表示车道内的第二交通参与者到达车道内的第二预设位置所需的时间。按照碰撞时间由小到大的排序,从车道内的所有第二交通参与者中选取预设数目的第二交通参与者,并将选取的第二交通参与者作为第一交通参与者。
具体的,对于目标车道区域内的每个车道,计算该车道内的交通参与者(即第二交通参与者)行驶至该车道内的第二预设位置(例如,如图5中的车道内的停止线)所需的时间,并将该时间作为该第二交通参与者对应的碰撞时间。将碰撞时间较小的第二交通参与者,即距离待通过路口区域较近的第二交通参与者作为该车道内的第一交通参与者。
其中,目标车道区域是车辆在通过待通过路口区域时所关注的车道区域,该车道区域内的交通参与者可能会对车辆造成影响。具体的,目标车道区域是基于车辆的当前位置和行驶方向确定的。例如,如图5所示,当车辆处于车道1,且车辆的行驶方向为直行时,该车辆关注的区域包括区域1和区域3,即目标车道区域包括区域1和区域3。
可选的,在确定车道内的第一交通参与者后,可以根据该车道对应的车道行驶方向确定该第一交通参与者对应的目标行驶车道。例如,如图5所示,车道2对应的车道行驶方向包括直行和右转,则车道2内的第一交通参与者对应的目标行驶车道包括车道3和车道4。
可选的,在确定待通过路口区域内的第一交通参与者对应的目标行驶车道时,可以根据以下两种方式进行确定。
一种方式为,对待通过路口区域进行划分,得到多个子区域,并获取各个子区域对应的边界线以及各个边界线对应的车道。对于待通过路口区域内的每个第一交通参与者,确定第一交通参与者对应的行驶朝向标志线。其中,行驶朝向标志线对应的指示方向与第一交通参与者的当前朝向一致。对第一交通参与者对应的行驶朝向标志线进行延长,以确定与延长后的行驶朝向标志线相交的目标边界线。获取目标边界线对应的车道,并根据目标边界线对应的车道确定第一交通参与者对应的目标行驶车道。
具体的,按照预设划分方式,对待通过路口区域进行划分,得到多个子区域,并确定各个子区域对应的边界线以及各个边界线对应的车道。其中,子区域对应的边界线(即外边界线)为待通过路口区域的部分边界线。例如,如图6所示,采用田字网关划分方式,将待通过路口区域等分为四个子区域,每个子区域的边界线为待通过路口区域的部分边界线。
对于待通过路口区域内的每个第一交通参与者,在该第一交通参与者的当前位置上绘制该第一交通参与者对应的行驶朝向标志线,该行驶朝向标志线对应的指示方向与该 第一交通参与者的当前朝向相同。按照该行驶朝向标志线(如图6所示的行驶朝向标志线)的指示方向,对该行驶朝向标志线进行延长,直至与某个边界线相交,并将相交的边界线作为第一交通参与者对应的目标边界线。利用目标边界线对应的车道确定该第一交通参与者对应的目标行驶车道。
可选的,当与第一交通参与者对应的目标边界线对应的车道的数量为一个时,可以直接将该目标边界线对应的车道作为该第一交通参与者对应的目标行驶车道。当该目标边界线对应的车道的数量为多个时,可以从目标边界线对应的车道中任意选取一个车道,也可以确定目标边界线与延长后的行驶朝向标志线之间的交点所在的边界线段,并将该边界线段对应的车道作为第一交通参与者对应的目标行驶车道。
其中,当子区域的边界线对应多个车道时,可以对该边界线进行分割,得到多个边界线段,每个边界线段对应一个车道。
另一种方式为,对于待通过路口区域内的每个第一交通参与者,获取第一交通参与者对应的驶出车道。驶出车道表示第一交通参与者进入待通过路口区域时所通过的车道。基于第一交通参与者上的预设点的当前位置,确定第一交通参与者对应的驶出车道内的第一预设位置与第一交通参与者上的预设点之间的连线,并对连线进行延长,以确定与延长后的连线相交的目标预设车道线段。获取与目标预设车道线段对应的车道,并根据目标预设车道线段对应的车道确定第一交通参与者对应的目标行驶车道。
具体的,如图7所示,当车辆处于车道1内时,对于待通过路口区域内的每个第一交通参与者,将该第一交通参与者上的预设点与该第一交通参与者对应的驶出车道内的第一预设位置进行连接,得到该第一预设位置与该预设点之间的连线,并延长该连线,直至该连线与某个预设车道线段相交。将与该连线相交的预设车道线段作为该第一交通参与者对应的目标预设车道线段,以供根据该目标预设车道线段对应的车道确定该第一交通参与者对应的目标行驶车道。
其中,第一预设位置可以是驶出车道内的停止线上的一个位置点,例如,第一预设位置为驶出车道内的停止线的中心点(如图7所示的中心点)。当然,第一预设位置也可以为驶出车道内的其它位置,在此,不对其进行限制。
可选的,当与第一交通参与者对应的目标预设车道线段对应的车道的数量为一个时,可以直接将该目标预设车道线段对应的车道作为第一交通参与者对应的目标行驶车道。当目标预设车道线段对应的车道的数量为多个时,可以从目标边界线对应的车道中任意选取一个车道,并将选取的车道作为目标行驶车道,也可以确定目标预设车道线段与交通参与者对应的连线的交点所在的子线段,并将该子线段对应的车道作为第一交通参与者对应的目标行驶车道。
其中,当预设车道线段对应多个车道时,可以对该预设车道线段进行分割,得到多个子线段,每个子线段对应一个车道。
步骤402、根据第一交通参与者的第一行驶状态信息、目标行驶车道和车辆的第二行驶状态信息,确定第一交通参与者对应的路权信息。其中,路权信息指示车辆对于第一交通参与者待采取的避让行为。
在本实施例中,基于车辆的当前位置和第一交通参与者的当前位置,从预设交通行驶规则表中确定与第一交通参与者的目标行驶车道和车辆的行驶方向对应的路权信息,并将其确定为第一交通参与者对应的路权信息。其中,交通行驶规则表包括路权与行驶方向的映射关系。
具体的,基于车辆的当前位置和车辆的行驶方向可以确定车辆的目标行驶方向,该目标行驶方向表示车辆具体的行驶方向,例如,如图3所示,车辆在车道1内行驶,当车辆的行驶方向为直行时,则确定车辆的目标行驶方向为由南向北直行。
对于每个第一交通参与者,基于该第一交通参与者对应的目标行驶车道确定该第一交通参与者对应的预测行驶轨迹,即行驶方向,并基于该第一交通参与者对应的行驶方 向和当前位置确定该第一交通参与者的目标行驶方向。从预设交通行驶规则中查找与第一交通参与者的目标行驶方向和车辆的目标行驶方向对应的路权信息,并将该路权信息作为该第一交通参与者对应的路权信息。例如,如图3所示,第一交通参与者对应的目标行驶方向为由西向东直行,车辆在车道1内行驶,当车辆的行驶方向为右转时,车辆对应的目标行驶方向为由南向东右转,车辆需避让该第一交通参与者,则该第一交通参与者对应的路权信息为第一路权。
其中,交通行驶规则表是根据实际的交通规则确定的。
步骤403、对于每个第一交通参与者,获取第一交通参与者的期望状态信息,并判断第一交通参与者的第一行驶状态信息和第一交通参与者的期望状态信息是否匹配。
在本实施例中,根据车辆的当前行驶情况,即第二行驶状态信息确定各个第一交通参与者的期望状态信息,即安全行驶状态,将第一交通参与者的第一行驶状态信息与第一交通参与者的期望状态信息进行匹配,以确定第一交通参与者是否处于安全行驶状态,即确定第一交通参与者是否会对车辆造成影响。
可选的,期望状态信息包括期望速度区间和/或期望距离区间。其中,期望速度区间表示第一交通参与者的安全行驶速度,即当第一交通参与者的当前行驶速度处于该期望速度区间时,该第一交通参与者不会对车辆造成影响。期望距离区间指示第一交通参与者与车辆之间的安全距离,即当第一交通参与者与车辆之间的当前距离处于该期望距离区间时,该第一交通参与者不会对车辆造成影响。
可选的,第一交通参与者的期望状态信息是根据第一交通参与者的上一时刻的行驶状态信息确定的。具体的,第一交通参与者的初始时刻的期望状态为空集,下一时刻的期望状态是基于该第一交通参与者当前时刻的运动状态、交互意图与系统延迟时间确定的。相应的,可以通过预设函数
Figure PCTCN2022071275-appb-000001
确定第一交通者在下一时刻的期望状态,其中,E n+1为第一交通参与者在下一时刻的期望状态,
Figure PCTCN2022071275-appb-000002
为第一交通参与者的当前运动状态,I n为第一交通参与者的当前交互意图,t delay为预设系统延迟时间,h()为该预设函数,其可以是相关人员根据实际需求自定义的。当然也可以采用其它方式进行确定,例如,通过将第一交通参与者当前时刻的运动状态、交互意图与系统延迟时间输入至训练好的神经网络模型中,以使该模型进行相应的处理,并输出第一交通参与者在下一时刻的期望状态。
其中,第一交通参与者的当前运动状态可以包括车辆的第一当前行驶速度、当前位置等信息。
可选的,期望状态信息是根据车辆的第二行驶状态信息设置的。在确定第一交通参与的期望速度区间时,从第一预设速度映射表中确定与车辆的当前行驶速度对应的速度区间,并将该速度区间作为该第一交通参与者的期望速度区间。其中,第一预设速度映射表包括期望速度区间与行驶速度的映射关系。当然,也可以采用其它方式进行确定,例如,采用相关人员自定义的预设速度区间确定函数进行确定,该第一预设速度区间确定函数的自变量为车辆的当前行驶速度。
为了提高第一交通参与者的期望速度区间的准确性,在确定第一交通参与者的期望速度区间时,可以结合第一交通参与者的当前行驶情况,即对于每个第一交通参与者,基于该第一交通参与者的当前位置和车辆的当前位置,确定该第一交通参与者与该车辆之间的距离,按照预设速度区间确定方式,确定与该距离和该车辆的当前行驶速度对应的速度区间,并将该速度区间作为该第一交通参与者的期望速度区间。
其中,在按照预设速度区间确定方式,确定与第一交通参与者和车辆之间的距离以及该车辆的当前行驶速度对应的速度区间时,可以从第二预设速度映射表中确定与该距离和该车辆的当前行驶速度对应的速度区间,也可以将该距离和车辆的当前行驶速度输入至训练好的神经网络模型中,以使该神经网络模型对该距离和车辆的当前行驶速度进 行相应的处理,输出与该距离和该车辆的当前行驶速度对应的速度区间。当然也可以采用其它方式确定期望速度区间,例如,采用相关人员自定义的第二预设速度区间确定函数进行确定,该第二预设速度区间确定函数的自变量为车辆的当前行驶速度以及第一交通参与者和车辆之间的距离。
相应的,在确定第一交通参与的期望距离区间时,可以基于车辆的当前行驶速度进行确定,其确定过程与上述基于车辆的当前行驶速度确定第一交通参与的期望速度区间的过程类似,在此,不再对其进行赘述。
为了提高确定第一交通参与者的期望距离区间的准确性,在确定第一交通参与者的期望距离区间时,可以结合第一交通参与者的当前行驶情况,即对于每个第一交通参与者,按照预设距离区间确定方式,确定与该第一交通参与者的当前行驶速度和该车辆的当前行驶速度对应的距离区间,并将该距离区间作为该第一交通参与者的期望距离区间。
其中,预设距离区间确定方式所包括的方式类型与上述预设速度区间确定方式所包括的方式类型类似,在此,不再对其进行赘述。
可选的,在期望状态信息包括期望速度区间时,判断第一交通参与者的第一行驶状态信息和第一交通参与者的期望状态信息是否匹配的过程包括:判断第一交通参与者的当前行驶速度是否在第一交通参与者的期望速度区间内。若在期望速度区间内,表明该第一交通参与者的当前行驶速度为安全速度,即该第一交通参与者不会对车辆的行驶造成影响,则确定第一行驶状态信息和期望状态信息匹配。若未在期望速度区间内,表明该第一交通参与者的当前行驶速度不是安全速度,即该第一交通参与者会对车辆的行驶造成影响,则确定第一行驶状态信息和期望状态信息不匹配。
可选的,在期望状态信息包括期望距离区间时,判断第一交通参与者的第一行驶状态信息和第一交通参与者的期望状态信息是否匹配的过程包括:判断第一交通参与者与车辆之间的距离是否在第一交通参与者的期望距离区间内。若在期望距离区间内,表明该第一交通参与者不会对车辆的行驶造成影响,则确定第一行驶状态信息和期望状态信息匹配。若未在期望距离区间内,表明该第一交通参与者会对车辆的行驶造成影响,则确定第一行驶状态信息和期望状态信息不匹配。
可选的,也可以基于期望速度区间和期望距离区间综合判断,即在第一交通参与者的当前行驶速度在第一交通参与者的期望速度区间内,且第一交通参与者与车辆之间的距离在第一交通参与者的期望距离区间内的情况下,确定该第一行驶状态信息和期望状态信息匹配,否则,则确定该第一行驶状态信息和期望状态信息不匹配。
步骤404、若第一行驶状态信息和期望状态信息匹配,则确定第一交通参与者不是交互参与者。
在本实施例中,在确定第一交通参与者的第一行驶状态信息和该第一交通参与者的期望状态信息匹配时,表明该第一交通参与者不会对车辆造成影响,即车辆无需与该第一交通参与者进行交互,则确定该第一交通参与者不是交互参与者。
步骤405、若第一行驶状态信息和期望状态信息不匹配,则获取第一交通参与者对应的交互意图,并根据第一交通参与者对应的交互意图确定第一交通参与者是否为交互参与者。其中,交互意图指示第一交通参与者的行驶优先级。
在本实施例中,在确定第一交通参与者的第一行驶状态信息与该第一交通参与者的期望状态信息不匹配时,表明该第一交通参与者当前行驶状态不是安全行驶状态,该第一交通参与者可能会对车辆造成影响,则进一步利用该第一交通参与者对应的交互意图确定该第一交通参与者是否为交互参与者。
可选的,交互意图包括优先行驶和避让行驶。其中,优先行驶指示第一交通参与者行驶的优先权较高,即车辆需要避让该第一交通参与者。避让行驶指示第一交通参与者行驶的优先权较低,即第一交通参与者需要避让该车辆。
其中,第一交通参与者在初始时刻的交互意图是根据第一交通参与者的路权信息 进行确定的,当第一交通参与者在初始时刻的路权信息为第一路权时,该第一交通参与者对应的交互意图为优先行驶;当第一交通参与者在初始时刻的路权信息不为第一路权时,该第一交通参与者对应的交互意图为第一交通参与者避让行驶。第一交通参与者在后续时刻的交互意图是根据第一行驶状态信息以及期望状态信息进行确定,其过程为:
在第一交通参与者的第一行驶状态信息和第一交通参与者的期望状态信息匹配的情况下,第一交通参与者对应的交互意图保持不变。在第一交通参与者的第一行驶状态信息和第一交通参与者的期望状态信息不匹配的情况下,将第一交通参与者对应的交互意图切换为另一状态。例如,第一交通参与者当前的交互意图为避让行驶,在第一交通参与者的第一行驶状态信息和第一交通参与者的期望状态信息不匹配的情况下,则将第一交通参与者当前的交互意图切换为优先行驶。
可选的,根据第一交通参与者对应的交互意图确定第一交通参与者是否为交互参与者,包括:若第一交通参与者对应的交互意图为优先行驶,表明车辆需避让该第一交通参与者,则确定第一交通参与者为交互参与者。
若第一交通参与者对应的交互意图为避让行驶,表明车辆无需避让该第一交通参与者,则确定第一交通参与者不为交互参与者。
步骤406、根据交互参与者对应的路权信息控制车辆行驶。
在本实施例中,响应于交互参与者中存在路权信息为第一路权的交互参与者,控制车辆停止行驶,其中,第一路权指示车辆进行避让。在交互参与者中不存在路权信息为第一路权的交互参与者的情况下,响应于交互参与者中存在路权信息为第二路权的交互参与者,控制车辆在待通过路口区域中的第一预设区域内低速行驶,其中,第二路权指示车辆不进行避让。
在本实施例中,当车辆需进入待通过路口区域时,判断确定的交互参与者中是否存在路权信息为第一路权的交互参与者,若存在,表明车辆需避让路权信息为第一路权的交互参与者,则控制车辆停止行驶,直至交互参与者中不存在路权信息为第一路权的交互参与者,即直至车辆关注的区域(例如、待通过路口区域、目标车道区域)内不存在路权信息为第一路权的交互参与者。
在确定交互参与者中不存在路权信息为第一路权的交互参与者时,判断该交互参与者中是否存在路权信息为第二路权的交互参与者,若不存在路权信息为第二路权的交互参与者,则车辆可以正常行驶,即控制车辆基于预设路径正常行驶通过待通过路口区域。若存在路权信息为第二路权的交互参与者,则控制车辆低速行驶,即控制车辆按照预设速度行驶,该预设速度的值较小。
可以理解,在车辆通过待通过路口区域的过程中,持续确定车辆关注的区域内的交互参与者,并根据该交互参与者的路权信息控制车辆进行相应的行驶。
可选的,在控制车辆低速行驶时,控制车辆在预设低速区域内低速行驶。在车辆驶出预设低速区域的情况下,控制车辆正常行驶。
其中,预设低速区域与车辆所在车道的停止线之间的距离在预设距离范围内。预设低速区域的数量可以为一个或多个,其与车辆的行驶方向相关,例如,如图8所示,车辆的行驶方向为直行,则预设低速区域包括区域a和区域b;又例如,如图9所示,车辆的行驶方向为右转,则预设低速区域包括区域c;又例如,如图10所示,车辆的行驶方向为左转,则预设低速区域包括区域d和区域e。
可选的,在控制车辆低速行驶的过程中,即响应于交互参与者中存在路权信息为第二路权的交互参与者,按照预设提示方式向路权信息为第二路权的交互参与者输出车辆通行提示信息,以使该交互参与者及时进行避让。其中,预设提示方式包括文字提示方式和/或语音提示方式。
在本实施例中,在确定第一交通参与者的期望状态信息时,考虑到受硬件性能带来的系统延迟,提高期望状态信息确定的准确性,从而可以准确地确定出交互参与者, 进而可以利用该交互参与者使无人车能最大限度的在保证安全性的前提下高效通过路口区域。
在本实施例中,获取第一交通参与者的期望状态信息,判断第一交通参与者的第一行驶状态信息和该第一交通参与者的期望状态信息是否匹配,以确定该第一交通参与者当前是否处于安全行驶状态,即确定该第一交通参与者是否会影响车辆的行驶。在确定第一交通参与者的第一行驶状态信息和该第一交通参与者的期望状态信息匹配时,表明该第一交通参与者当前不会影响车辆的行驶,则确定该第一交通参与者不是交互参与者,即车辆无需与该第一交通参与者进行交互。在确定第一交通参与者的第一行驶状态信息和该第一交通参与者的期望状态信息不匹配时,进一步利用第一交通参与者对应的交互意图确定该第一交通参与者是否需与车辆进行交互,即确定该第一交通参与者是否为交互参与者,实现交互参与者的准确确定,即实现车辆需进行交互的交通参与者的准确确定,从而使得车辆可以及时与需进行交互的交通参与者进行交互,保证交互的及时性。
在本实施例中,通过预测第一交通参与者的目标行驶车道,即行驶轨迹,并结合实际的交通规则,确定第一交通参与者的路权信息,从而在基于从第一交通参与者中确定的交互参与者的路权信息控制车辆进行行驶时,可以使车辆合理及时地与交互参与者进行交互。
