具体实施方式
目前,自动驾驶应用程序通常是基于ROS、Adaptive AotoSAR等平台开发。如图1所示,为现有技术中自动驾驶应用程序与不同开发平台对接的示意图。基于ROS平台开发的自动驾驶应用程序与基于AP平台开发的自动驾驶应用程序通信时,或者将基于ROS平台开发的自动驾驶应用程序迁移到AP平台运行时,需要将基于ROS平台开发的自动驾驶应用程序中的底层用于通信的接口代码进行修改,修改成如图1中的通信网关message gateway。同时,还需要在AP平台增加消息转换机制的代码,如图1中的人机交互接口(human machine interface,HMI)服务。其中,通信网关能够将AP平台的自动驾驶应用程序的消息转换为ROS平台支持的格式,也能够将ROS平台的自动驾驶应用程序的消息转换为AP平台支持的格式,HMI将AP平台的自动驾驶应用程序的消息通过接口发送给 通信网关,将通信网关的消息通过接口发送给AP平台的自动驾驶应用程序。
所以,目前的不同平台的自动驾驶应用程序之间的通信方式需要修改人员具有代码开发或修改能力,且修改工作量较大,实现较为复杂。
鉴于上述技术问题,本申请这里提供一种自动驾驶应用程序在不同开发平台间对接的方法。当然,本申请实施例的技术方案可以应用于各种自动驾驶开发平台,例如:AP平台、ROS平台,未来的自动驾驶开发平台等。本申请实施例的技术方案可以应用于将基于第一开发平台开发的自动驾驶应用程序迁移到第二开发平台运行时的场景,其中第一开发平台不同于第二开发平台;或者,还可以应用于第一自动驾驶应用程序运行在第一开发平台时,与运行在第二开发平台的第二自动驾驶应用程序通信时的场景,其中第一自动驾驶应用程序是基于第一开发平台开发的,第二自动驾驶应用程序是基于第二开发平台开发的。
为了能够降低自动驾驶应用程序与不同开发平台对接时的代码修改量,本申请实施例提供一种自动驾驶应用程序在不同开发平台间对接的方法,通过该方法,在目的开发平台预先设置N个接口对接功能,其中第i个接口对接功能用于处理基于第i个平台开发的自动驾驶应用程序的消息,i取遍1到所述N中的任意一个正整数。针对任一自动驾驶应用程序,在所述N个接口对接功能中,确定所述任一自动驾驶应用程序对应的目标接口对接功能,基于目标接口对接功能实现所述任一自动驾驶应用程序与目的开发平台的对接。
为便于理解本申请实施例,首先以图2中示出的自动驾驶应用程序在不同开发平台间对接的系统为例详细说明本申请实施例所应用到的场景。不失一般性的,以将基于第一开发平台开发的自动驾驶应用程序迁移到第二开发平台运行时的场景为例进行说明。如图2所示,该系统中包括AP平台的应用程序(application,APP)APP1,ROS平台的APP2,XX平台的APP3。其中,需要将APP2和APP3迁移到AP平台运行。因此,在AP平台预设的N个接口对接功能中查找所述APP2对应的接口对接功能1,以及查找APP3对应的接口对接功能2。其中,接口对接功能1用于与基于ROS平台开发的自动驾驶应用程序对接,接口对接功能2用于与基于XX平台开发的自动驾驶应用程序对接。故此,可以基于接口对接功能1将APP2迁移到AP平台运行,基于接口对接功能2将APP3迁移到AP平台运行。或者,还可以基于接口对接功能1实现APP2与APP1的通信,基于接口对接功能2实现AAPP3与APP1的通信。
本申请实施例描述的系统架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案,并不构成对于本申请实施例提供的技术方案的限定,本领域普通技术人员可知,随着系统架构的演变和新业务场景的出现,本申请实施例提供的技术方案对于类似的技术问题,同样适用。应理解,图2仅为便于理解而示例的简化示意图,该系统中还可以包括其他的自动驾驶平台,图2中未予以画出。
以下对本申请实施例中出现的词语进行解释,以便理解本申请实施例提供的技术方案:
1)对接,包括将自动驾驶应用程序迁移到一开发平台上运行,或者还包括自动驾驶应用程序与一开发平台或一自动驾驶应用程序进行通信。例如,将基于a平台开发的自动驾驶应用程序迁移到b开发平台上运行,或者基于a平台开发的自动驾驶应用程序与b开发平台进行通信。其中,a平台与b平台为不同平台。
另外,本申请实施例中的术语“系统”和“网络”可被互换使用。“至少一个”是指一个或者多个,“多个”是指两个或两个以上。“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B的情 况,其中,A,B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。以下至少一项(个)下或其类似表达,是指的这些项中的任意组合,包括单项(个)或复数项(个)的任意组合。例如,a,b,或c中的至少一项(个),可以表示:a,b,c,a-b,a-c,b-c,或a-b-c,其中a,b,c可以是单个,也可以是多个。
除非有相反的说明,本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分,不用于限定多个对象的顺序、时序、优先级或者重要程度。
此外,本申请实施例和权利要求书及附图中的术语“包括”和“具有”不是排他的。例如,包括了一系列步骤或模块的过程、方法、系统、产品或设备,不限定于已列出的步骤或模块,还可以包括没有列出的步骤或模块。
通过本申请实施例中上述应用场景的介绍,下面针对所述自动驾驶应用程序在不同平台间的对接方法进行具体介绍。
如图3所示,为本申请提供的一种自动驾驶应用程序在不同开发平台间对接的方法的落成示意图,可以包括以下步骤:
步骤301:接收将至少一个自动驾驶应用程序与目的开发平台对接的指令,所述目的开发平台上预设有N个接口对接功能。
其中,第i个接口对接功能用于将基于第i个自动驾驶平台开发的自动驾驶应用程序与所述目的开发平台对接;所述i取遍1到所述N中的任意一个正整数。
一种可能的实现方式中,可以接收所述任一自动驾驶应用程序的属性消息。其中,属性消息中可以包括开发所述任一自动驾驶应用程序的源平台信息,则可以在N个接口对接功能中查找所述源平台信息对应的目标接口对接功能。其中,目的开发平台可以是AP平台,源平台可以是ROS平台。
基于该方案,能够通过自动驾驶应用程序的源平台信息,自动生成用于进行消息格式转换的代码,降低修改人员对自动驾驶应用程序的底层代码的修改量,降低修改人员的工作量,实现简单,提高自动驾驶应用程序在不同平台间对接的效率。
另一种可能的实现方式中,属性消息中可以包括自动驾驶应用程序的服务等级,自动驾驶应用程序对应的服务等级越高,则对应的待处理的数据的优先级越高。举例来说,在将ROS平台的APP1和APP2迁移到AP平台运行时,可以选择APP1的服务等级为a级,APP2的服务等级为b级,a级高于b级,则在APP1的待处理的数据的优先级高于APP2的待处理的数据的优先级。
一示例性的,针对任一自动驾驶应用程序,可以将自动驾驶应用程序的待处理的数据发送至不同的服务级别协议(service level agreement,SLA)队列中。其中,不同的SLA队列用于分别存储不同服务等级的待处理的数据。举例来说,一般SLA队列可以存储服务等级为中的待处理的数据,如服务等级为b或服务等级为c的自动驾驶应用程序的待处理的数据。低时延SLA队列可以存储服务等级高的待处理的数据,如服务等级为a的自动驾驶应用程序的待处理的数据。
需要说明的是,在处理待处理的数据时,可以优先处理低时延SLA队列中的待处理数据。一示例性的,在低时延SLA队列中不为空时,在低时延SLA队列中获取待处理的数据并进行处理,在低时延SLA队列为空时,在一般SLA队列中获取待处理的数据并进行处理。
另一示例性的,可以根据预设的规则从不同的SLA队列中获取待处理的数据。例如,可以是在低时延SLA队列中获取第一预设数量的待处理的数据并处理后,在一般SLA队列中获取第二预设数量的待处理的数据并处理。其中,第一预设数量和第二预设数量根据经验值预先确定。
基于该方案,在实现多个自动驾驶应用程序与目的开发平台的对接时,由于自动驾驶应用程序的待处理的数据较多,对不同自动驾驶应用程序区分服务等级,则可以根据服务等级处理自动驾驶应用程序的待处理的数据,能够确保低时延的数据被优先处理。
再一种可能的是实现方式中,属性消息中还可以包括自动驾驶应用程序的发送端口和接收端口,以及发送端口的类型和接收端口的类型。举例来说,自动驾驶应用程序的通信端口可以包括端口1、端口2、端口3和端口4。可以在各通信端口中选择发送数据的发送端口,例如发送端口为端口2和端口1,以及在各通信端口中选择接收数据的接收端口,例如接收端口为4。则,自动驾驶应用程序通过端口2和端口1将数据发送给目的开发平台,通过端口4接收目的开发平台发送的数据。其中,发送端口的类型和接口端口的类型可以包括单播、广播、多播等。
举例来说,可以选择前述自动驾驶应用程序的端口2为广播,端口1为单播、端口4为单播。相应的,AP平台可以订阅自动驾驶应用程序的消息,并在自动驾驶应用程序通过端口2广播数据后,AP平台可以接收端口2广播的数据。AP平台还可以接收端口1单播的数据。另外,AP平台可以通过单播的方式,将数据通过端口4发送给自动驾驶应用程序。
本申请实施例中还可以选择自动驾驶应用程序的数据的数据结构。一示例性的,可以预先设置不同的数据结构。例如,可以设置数据结构A为“int a;sting b”,数据结构B为“int c;string d”等。并在属性消息中携带自动驾驶应用程序的数据结构标识。例如,自动驾驶应用程序的端口2的数据结构标识为数据结构A,端口1的数据结构标识为数据结构B,端口4的数据结构标识为数据结构A。
另一示例性的,可以在选择自动驾驶应用程序的发送端口和接收端口时,设置发送端口发送的数据和接收端口接收的数据的数据结构。例如,自动驾驶应用程序的端口1的数据结构为“int a;int b”,端口2的数据结构为“int c;string d”,端口4的数据结构为“int e;string f”。
基于该方案,能够选择自动驾驶应用程序的数据结构,并通过选择的数据结构接收和发送自动驾驶应用程序的数据,实现自动驾驶应用程序与不同自动驾驶开发平台的对接。
本申请实施例中接收到上述说明中的属性消息后,目的开发平台能够将在预设的N个接口对接功能中获取目标接口对接功能。
步骤302:针对任一自动驾驶应用程序,在所述N个接口对接功能中查找所述任一自动驾驶应用程序对应的目标接口对接功能。
一种可能的实现方式中,在所述N个接口对接功能中,查找所述任一自动驾驶应用程序的源平台信息对应的接口对接功能模板;将所述属性消息添加至查找到的接口对接功能模板,作为目标接口对接功能。
一示例性的,可以通过目的开发平台中的配置工具预设N个接口对接功能的代码模板。在接收到自动驾驶应用程序的属性消息后,从预设的N个接口对接功能的代码模板中查找属性消息中的源平台信息对应的目标接口对接功能的模板。以及,将属性消息中的自动驾 驶应用程序的属性消息添加到查找到的代码模板中,从而生成自动驾驶应用程序的目标接口对接功能的代码。
如图4所示,目的开发平台为AP平台。需要实现XX平台的自动驾驶应用程序APP2与AP平台的自动驾驶应用程序APP1的通信。图4中的配置工具(define services)接收XX平台的自动驾驶应用程序的属性消息,并在N个预设的接口对接功能中查找XX平台的目标接口对接功能的代码模板。并通过应用服务界面(service interface description)以及APP2的属性消息生成自动驾驶应用程序的目标接口对接功能的代码。XX平台的自动驾驶应用程序可以通过自动生成的代码实现与APP1的通信。
步骤303:基于所述目标接口对接功能,将所述任一自动驾驶应用程序与所述目的开发平台对接。
如图5所示,为本申请实施例中基于目标接口对接功能实现与目的开发平台对接的示意图。图5中,目的开发平台为AP平台,需要实现ROS平台的APP2与AP平台的APP1的通信。通过接收上述说明中的APP2的属性消息,自动生成如图5中的接口对接功能mgw service的代码。其中,mgw service通过ROS消息接口1接收APP2的数据,并根据APP2的服务等级将接收到的数据存储至低时延SLA队列。mgw service从低时延SLA队列中获取APP2的待处理的数据,并将待处理的数据的格式转换成AP平台的期望格式。mgw service将格式转换后的待处理的数据通过Rport发送给APP1。相应的,mgw service通过Rport接收APP1的数据,并根据APP1的服务等级将接收到的数据存储至一般SLA队列。mgw service可以在低时延SLA队列中的数据为空时,从一般SLA队列中获取APP1的待处理的数据,并将获取的数据的格式转换成ROS平台的期望格式。mgw sevice将格式转换后的数据通过ROS消息接口2发送给APP2。
