技术领域
本申请实施例涉及计算机技术领域,特别是指一种车路协同系统、模拟仿真方法、车载设备和路侧设备。

车路协同作为车联网V2X(Vehicle to Everything,车辆到万物)业务的基础能力,旨在避免交通事故、提升道路安全、缓解拥堵、降低能耗以及降低环境污染,并满足车辆辅助驾驶、自动驾驶等业务的必要输入。
RSU(Road Side Unit,路侧单元)与OBU(On-Board Unit,车载单元)作为车联网车路协同的重要设备环节,通过无线或有线通信管道,可以为车路协同平台云端提供必要的信息输入、接收云端或其他设备端的信息。
目前,我国正大力发展智慧交通、智能驾驶等产业技术创新园区,积极推进5G(the 5th Generation mobile communication technology,第五代移动通信技术)、MEC(Mobile Edge Computing,移动边缘计算)边缘云的建设和应用。但是,目前的车载终端和路侧设备的制造商众多,通信协议换人设备行为尚未达到完全统一,而由于车路协同系统中的主要场景都会涉及多种外部终端设备和多种通讯协议以及设备之间的相互通讯,导致在系统的调试、优化、开发方面具备的不可见风险、不可调节因素众多。
传统车路协同设备仿真方案中,单一化考虑路侧或车载设备的业务逻辑,设备通信协议以及设备行为逻辑未标准化而复杂多变,集中式服务端设计未考虑真实场景下多级云和多类型设备相互协作,导致现有的车路协 同系统中,沟通过程冗长且充满噪音,开发及验证的成本较大。

本申请实施例中,边缘云可以进行路侧设备、车载设备的仿真数据收集,仿真数据来源于真实设备数据可以通过三种方式获得。其中,真实设备数据来源于经过车辆协同平台中路端、车端的真实设备通过仿真SDK在 真实路侧设备、车载设备运行时进行自动化的数据采集、数据过滤,以及标准化编码与转码、转发所获取的数据;编辑录入方式来源于人工在地图上采集GPS点位(例如,车辆行驶路径上的连续GPS点位)、录入设备属性(例如,交通信号灯灯态变化的频率)、运行或行驶状态(例如,车速、方向角等)、仿真事件(例如,道路施工事件)等信息,再做与真实设备数据上报方式中一致的标准化编码与转码;车路协同场景仿真时对真实设备数据与编辑录入的仿真设备数据进行融合,实现真实设备与仿真设备的自由组合(例如,真实路端设备与仿真车载设备组合,或仿真路端设备与真实车载设备的组合),为车路协同平台验证大量路端设备和车载设备的车路协同能力提供了高效灵活的实践方案,还可以在特定场景下减少真实设备的投入,从而节省了成本。

如图7所示,在设置自定义路径元数据的时候,需按路径规划设想进行人工切分。具体的,可以通过人工在可视化地图页面选点的方式设置切分路段的开始点和起始点,并选择两点行驶的策略信息。例如,开始点、结束点的时间、速度、行向角以及预设切分的粒度等信息。
本申请一实施例中,边缘云收集所述路径元数据的流程(即元路径行驶点模拟流程)如图7所示:

S704:收集汇总运行点;
S705:存储运行点,形成路径元数据。
在计算完成了整段脚本后,收集所有的模拟点以及各段路的开始结束点,存入数据库,则完成了一次路径元数据的录入。
需要说明的是,在场景中,车辆的行驶行为可能会根据场景事件进行智能、实时的变化,如果没有其他外界因素影响,则车辆应该按照路径元数据进行仿真运行。
本申请一实施例中,仿真基础路径元数据(即路径元数据)是通过算法智能的加入模拟的行驶位置信息点,可以使车辆运行行为能够更加顺畅、真实。
可选地,所述边缘云在路径上对路段进行切分,包括以下至少一项:

根据角度对路段进行切分;
根据角度和加速度对路段进行切分。
具体的,如图7所示,可以按照速度变化和角度变化分为以下四种切分方式:
(一)按两点距离均分:假定车辆为直线行驶,以及假定车辆是匀速行驶,可以计算输入时间经过两点之间距离的速度和两点之间直线相对正北为0的角度,然后按照设置的切分粒度,等分当前路段,并根据距离和角度计算出等分点的经纬度。
(二)按加速度切分:假定车辆直线行驶,且开始、结束位置点信息中车辆速度不同,可根据速度差和时间计算出加速度,根据设置的切分粒度、加速度、时间、两点之间直线相对正北的角度,按照行驶距离进行计算,得出每一个模拟点的经纬度,直至结束点。
(三)按角度切分:假定车辆速度不变,可以按照当前点的航向角度和结束点的航向角度,得出两点在行驶过程中角度的变换;以两点为虚拟圆上两点,两点间的距离作为圆直径,按照设置切分粒度等分相差角度和 相差距离,计算出圆弧上等分点经纬度,这种方法可适用于模拟车辆匀速转弯的场景。
(四)按角度、加速度切分:假定速度变化(即开始点和结束点速度信息不一致),可以获取两点时间差,并计算加速度;按照当前点的航向角度和结束点的航向角度,以两点为虚拟圆上两点,两点间的距离作为圆直径,按照设置切分粒度、加速度、等分角,计算出圆弧上行驶点经纬度,这种方法可适用于模拟车辆变速转弯的场景。

需要说明的是,关键点场景事件设置,即关键点行为编织,在路径上设置场景事件,只可用于互动融合模拟场景,主要是指在规划好的路径元数据上设置需要执行的场景行为,该过程具备以下特点:包含17种基础标准国标场景行为事件;多个国标场景行为可在互动仿真路径元数据上进行一定程度上的自由组合;具备指定场景发生的道路规划和范围;真实设备与模拟设备可以在场景中混合使用,例如,真实路侧设备可以为模拟车辆提供自动驾驶或者行为决策的数据支撑,反之,模拟路侧设备亦可为真实V2X道路测试车辆提供动态、可信和标准的支撑数据。
可选地,所述边缘云对所述场景事件进行校验,包括:判断所述场景事件之间以及所述场景事件与所述路径元数据之间是否存在行为互斥;若不存在行为互斥,则校验通过;否则,校验失败。
也就是说,需满足以下约束:场景事件之间不能存在行为互斥,例如道路施工事件和交通灯交互;场景事件和路径元数据不可存在行为互斥,例如直行车道上不可执行左转辅助。
本申请实施例中,通过场景仿真引擎,将来源于在线设备SDK上报制定(即设备数据在线录制)、自定义编排元数据制定(即在线元数据制定)、与模板数据导入(即模版导入)制定的数据,按照国标场景定义的前向碰撞预警、交叉路口碰撞预警、左转辅助等17种基础场景通过一定程度的人工组合、设置和算法自动生成的方式编排为适用于仿真设备的场景脚本,实现了路侧设备、车载设备的仿真场景编排,用于车路协同系统、路侧设备、车载设备能力的验证。
通过仿真模拟,可以提供不易在真实世界中创造的事件和条件,例如,拥堵事件、车辆失控预警事件、道路施工事件,以及大风、大雾、路面结冰等道路天气危险事件,避免在场景验证时无法实现事件产生的条件,提高了场景验证效率。
另外,由于仿真场景能直接产生危险事件,避免了真实的车辆在行驶中为了验证仿真场景对驾驶员、行人、道路等造成危险。
此外,当17种基础场景经过编排、融合后能够形成全新的组合场景,进一步可构建算法模型,采用机器学习等算法,为特定场景的自动驾驶行为提供算法训练功能,可应用于边缘云辅助驾驶方向的机器学习、算法训练,商业应用更加广泛。
本申请实施例中,通过仿真车载设备、路侧设备,并与边缘云中仿真环境接入的真实设备混合、共同作用于车路协同场景,能够减少大量真实设备的部署以降低成本,并能创造真实世界中难以实现的场景条件。
例如,主车(host vehicle,HV)在行驶过程中,在场景中预设前方不远的道路上有一辆仿真的车辆(remote vehicle,RV),而真实的路边激光雷达检测到了左前方有行人,此时主车应进行减速,而不是按照场景预设的 从左侧进行超车。
本申请在模拟仿真方面可以做到真实与模拟设备交替使用,易于扩展,且在后续的数据增值性、应用广泛性、机器学习数据多样性、通用性等方面较优,解决了现有技术中常见的由单一服务器仿真实现,导致做到分布式数据融合,以及人、车和物的相关智能算法训练的问题。

需要说明的是,如果当前执行场景的设备是车端(即车载设备),则车端对脚本数据进行解码、与交通道路网络或其他设备元数据建立关联关系等预处理;如果场景事件造成了汽车必须更改行驶路径,则车端通过仿真规划出不同于预设脚本、新的行驶路径(包括GPS点位、转向角、行驶速度等);采用算法进行场景事件的处理,例如,采用深度学习、强化学习等方法不断改进事件处理的最优解。如果当前执行场景的设备是路端(即路侧设备),则路端对脚本数据进行解码、与交通道路网络或其他设备元数据建立关联关系等预处理。
