背景技术
随着网联技术和自动驾驶技术的发展,多家企业的相关产品纷纷“装车”,对于相同场景或者功能,各家制定的安全策略都不尽相同,例如,限速预警场景,有的厂家的策略是超速10%以后才会提醒,有的厂家的策略是预测其可能会超速时就会提醒,前者有超速被罚的风险,后者则有可能会影响用户体验。从市场多样性的角度考虑,没有必要统一所有厂家的安全策略,因此,只需要制定最低要求即可。
由于标准中只定义最低要求,如最晚触发时机,本车辆在获取周围车辆信息时,只能得知周围车辆的最晚触发时机,无法判断其实际的触发时机,甚至无法获知其触发时机的范围,因此本车辆一般会针对所有车辆执行统一的策略,这样,存在一定的安全隐患,且会影响协作效率。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。在下面的描述中,提供诸如具体的配置和组件的特定细节仅仅是为了帮助全面理解本公开的实施例。因此,本领域技术人员应该清楚,可以对这里描述的实施例进行各种改变和修改而不脱离本公开的范围和精神。另外,为了清楚和简洁,省略了对已知功能和构造的描述。
应理解,说明书通篇中提到的“一个实施例”或“一实施例”意味着与实施例有关的特定特征、结构或特性包括在本公开的至少一个实施例中。因此,在整个说明书各处出现的“在一个实施例中”或“在一实施例中”未必一定指相同的实施例。此外,这些特定的特征、结构或特性可以任意适合的方式结合在一个或多个实施例中。
在本公开的各种实施例中,应理解,下述各过程的序号的大小并不意味着执行顺序的先后,各过程的执行顺序应以其功能和内在逻辑确定,而不应对本公开实施例的实施过程构成任何限定。
在本公开所提供的实施例中,应理解,“与A相应的B”表示B与A相关联,根据A可以确定B。但还应理解,根据A确定B并不意味着仅仅根据A确定B,还可以根据A和/或其它信息确定B。
在进行本公开实施例的说明之前,首先对与本公开实施例相关的技术或问题进行说明:
目前各车辆可获取到的周围车辆的信息主要包括车辆的实时行驶信息(速度、位置等)和车辆的基本属性信息(如尺寸、车辆类型等),这些信息可通过如下两种方式获取:
(1)通过网联方式获取,如基础安全消息(Basic Safety Message,BSM): 包括车辆的实时行驶信息(位置、速度、加速度),车辆的属性信息(如车辆类型:轿车/货车等、车辆尺寸)等;
通过(1)网联方式获取信息后,可用于安全和效率类的网联场景,目前业内公认的网联场景包括17个一阶段场景和12个二阶段场景,具体如下表1所示:
表1一阶段和二阶段应用场景列表
(2)通过传感器感知方式获取:包括车辆的实时行驶信息(速度、加速 度、与自车位置关系),车辆的属性信息(如车辆尺寸)等。
通过(2)传感器感知方式获取信息后,可用于安全类的自动驾驶功能,目前主要的已经标准化的功能如下:
表2标准化功能列表
针对不同的网联场景和自动驾驶功能,相关标准中一般只会定义最低要求,如最晚触发时机等,实际的参数则由各家自行实现。此外,标准定义的这些要求会普遍适用于M类汽车(至少有四个车轮并且用于载客的机动车辆)和N类汽车(至少有四个车轮并且用于载货的机动车辆),但是,虽然同属于M类或N类汽车,其车型、车辆尺寸、车辆制动能力等都有较大区别,各种车型在商用之前,可能会在满足标准的前提下,根据车辆的安全行驶参数(车型、车辆尺寸、制动能力等影响车辆安全行驶的所有相关参数),调整不同网联场景或自动驾驶功能的安全和效率策略,如触发时机等,但这些信息是目标车辆无法获知的。因此,目标车辆也无法针对不同的车辆制定不同的安全策略,多是执行统一的策略,但是,统一的策略,要么会有安全风险,要么会影响场景/功能执行的效率。
下面结合附图,通过具体的实施例及其应用场景对本公开实施例提供的信息传输方法、装置、车辆及车联网设备进行详细地说明。

b)在所述网联化渗透率大于预设渗透率的情况下,根据所述第一车联网设备的智能化等级调整所述第一消息;
这里,需要说明的是,该预设渗透率例如为0,也就是说,在第一车辆周围具有网联功能的车辆或设备时,第一车辆可以基于该具有网联功能的车辆或设备的智能化等级调整该第一消息中的内容,以确保该具有网联功能的车辆或设备能够识别该第一消息中的内容;
c)在所述网联化渗透率小于或等于所述预设渗透率的情况下,停止发送所述第一消息。

作为一个具体的实现方式,所述根据所述第一消息,获取第二信息,包括以下至少一项:
(1)基于预先配置的对应关系表,获取所述第二信息;也就是说,车联网设备中预先配置有车辆特征信息与第一信息、第一信息的类别、第一信息的等级中的至少一个的对应关系,通过查表的方式,可以直接获得与第一消息中的车辆特征信息对应的第一信息、第一信息的类别和第一信息的等级中的至少一个;
(2)基于预先配置的计算规则,获取所述第二信息;也就是说,车联网设备可以基于预先配置的计算规则,基于第一消息中的车辆特征信息获得第一信息、第一信息的类别和第一信息的等级中的至少一个;
(3)将所述第一消息上传至第四设备,并从所述第四设备获取所述第二信息,其中,所述第四设备用于根据所述第一消息生成所述第二信息。
这里,需要说明的是,第四设备可以为云服务器或移动边缘计算(Mobile Edge Computing,MEC)服务器等,也就是说,在车联网设备在本地不能基于车辆特征信息获得第二信息的情况下,车联网设备可以将车辆特征信息发送给第四设备,由第四设备协助获取该第二信息。具体的,第四设备基于该车辆特征信息,查询或计算获得第一车辆的第一信息,并按照行业管理对第 一信息进行分类/分级,确定其类别和/或等级后,将第一信息、第一信息的类别和第一信息的等级反馈给车联网设备。
这里,还需要说明的是,在车联网设备为车辆的情况下,该第四设备还可以为RSU。
以车联网设备为第二车辆为例,车联网设备接收到第一车辆发送的第一消息后,在确定第一消息进包括车辆特征信息的情况下,第二车辆通过查表的方式或按照预配置的计算规则,根据车联网特征信息得到第二信息,或者,若第二车辆在确定无法在本地获得第二信息,则将车辆特征信息发送给第四设备,由第四设备协助确定该第二信息,并接收第四设备发送的第二信息;然后,第二车辆基于该第二信息生成与该第一车辆相关的安全策略。
承接上例,对车联网设备为第二车辆的情况下的具体实例进行说明:
实例一,第一车辆发送的第一消息包括车辆特征信息,第二车辆直接获取该第一消息,并决定是否触发场景的过程如下:
第一车辆和第二车辆都为L3级+的自动驾驶车辆,第一车辆计划触发协作式变道场景,在场景触发时或者在场景触发前,第一车辆发送车辆特征信息(车辆生产厂、出厂日期、自动驾驶系统版本、车型等),第二车辆接收到车辆特征信息后,将上述信息上传至云端服务器,云端服务器返回上述车辆特征信息所对应的车辆安全行驶相关的信息(整车制动参数、制动系参数等),判定第一车辆需要的安全变道间隙为Ds,而当前第二车辆与其前后方车辆的间距较小,很难满足间隙Ds的需求,则第二车辆决定不参与协作第一车辆的协作式变道场景。
实例二,第一车辆发送第一信息、第一信息的类别/第一信息的等级,第二车辆直接获取这些信息的具体实现过程:
第一车辆发送车辆安全行驶相关的类别/等级信息(制动等级为Hard,安全策略类别为激进),第二车辆获取该类别/等级信息后,判定第一车辆需要制动的距离较长,制动难度较大,且其行驶过程中的安全策略为激进型,即场景触发时机较晚或提醒频次较少,则第二车辆应适当扩大与第一车辆的安全距离,以及调整与第一车辆相关的场景的预警时机等。
作为一个可选的实现方式,所述第二车辆的安全策略包括以下至少一项:
(1)第二车辆的触发时机,所述触发时机为与所述第一车辆请求的业务相关联的触发时机;例如,前向碰撞预警场景下,第一车辆在第二车辆前方,第一车辆紧急制动时,第二车辆应结合第一车辆的第二信息,预测第一车辆的运行轨迹,进而决定自身给驾驶员发送提醒或给控制器发送控制指令的触发时机;
(2)所述第二车辆与所述第一车辆的安全距离;例如,根据第一车辆的第二信息,确定第二车辆与第一车辆的安全距离,并在行驶过程中低于安全距离时给驾驶员发送提醒或给控制器发送控制指令;
(3)所述第二车辆能否协助所述第一车辆完成所述第一车辆请求的业务的指示信息;例如,协作式车辆汇入场景下,第一车辆位于匝道,第二车辆位于主路,二者相近时间到达汇入口时,第二车辆根据第一车辆的第一信息,确定当前是否让行第一车辆;
(4)所述第二车辆协助所述第一车辆完成所述第一车辆请求的业务的操作,例如,协作式变道场景下,第一车辆向第二车辆发送变道请求,第二车辆应结合第一车辆的第二信息,预留出第一车辆变道所需要的安全间隙。
作为另一个可选的实现方式,所述协同策略包括以下至少一项:
第三车辆的触发时机,所述触发时机为与所述第一车辆关联的业务的触发时机;
所述第三车辆与所述第一车辆的安全距离;
所述第三车辆能否协助所述第一车辆完成请求的业务的指示信息;
所述第三车辆协助所述第一车辆完成所述第一车辆请求的业务的操作;
车辆通行次序;
车辆通行间隔;
其中,所述第三车辆用于协助所述第一车辆完成所述第一车辆请求的业务。
也就是说,在车联网设备为第三方设备的情况下,第三方设备可以基于第一车辆周围的交通情况确定与第一车辆的行驶相关的第三车辆,从而使得第三方设备基于该第二信息和第三车辆的相关信息确定协同策略,使得第三车辆协助第一车辆通行。
在车联网设备为第三方设备的情况下,第三方设备接收第一车辆发送的第一消息,第三方设备根据该第一消息,获取第二信息,并基于该第二信息指定协同策略,其中,该协同策略可以是针对第一车辆的,如:第一车辆变道、通过路口或砸到汇入口的时机等;该协同策略也可以是针对第一车辆在内的所有车辆的安全策略,如:交叉路口的信号灯控制/车辆通信、匝道口的车辆汇入顺序、优先车辆的管控间隙、动态车道控制策略等。
承接上例,第一车辆发送车辆行驶安全相关信息,第三方设备制定针对第一车辆的安全策略的过程如下:
第一车辆通过汇入口,主路上车流量较大,第三方设备如RSU负责该汇入口主路和匝道车辆的协同。第一车辆发送第一消息,第一消息中包含第一车辆的安全策略(协同场景下的安全间隙Ds),RSU接收到第一车辆的第一消息后,判定主路一定范围内,哪两辆车之间的间隙满足第一车辆安全间隙Ds的需求,并据此判定第一车辆的汇入时机,并向第一车辆发送具体的的汇入指令。
进一步地,作为一个可选的实现方式,所述方法还包括:
在所述车联网设备为第三方设备的情况下,向所述第一车辆和/或第三车辆发送所述协同策略,所述第三车辆用于协助所述第一车辆完成所述第一车辆请求的业务。
也就是说,在第三方设备制定协同策略之后,第三方设备将该协同策略发送给对应的车辆,以实现车辆的协同。
本公开实施例的信息传输方法中,第一车辆在不同场景下触发第一消息的发送,并根据第一车辆当前的环境信息和/或业务情况调整发送的第一消息的内容,使得接收方能够基于接收到的第一消息,获得车辆更精准或更贴近实际的性能或策略信息,在进行车辆轨迹等预测时,可得到更贴近实际的预测结果,避免预测和实际结果的较大偏差对安全策略的影响,如此,能够针对不同车辆制定不同的安全策略,最大化的保证车辆的安全性,使协作过程更高效,避免了不必要的交通资源浪费。
