在图1或图2所示的网络架构中,SL为短距离通信方式,一般覆盖距离为1000米以内,可实现车辆之间、车辆与RSU、车辆与行人/非机动车等之间的通信。Uu空口是车辆与网络设备或其它实体之间的通信接口,可以实现车辆与网络设备的通信。比如,车辆可通过接入网络设备与核心网设备进行通信,车辆与接入网设备之间可通过Uu空口进行连接,接入网设备与核心网设备之间可通过有线方式进行连接。通过接入网设备,核心网设备可以实现和任一车辆或路边基础设施之间的通信,实现车到网络到一切(vehicle to network to everything,V2N2X)的场景。
基于图1或图2所示的网络架构,提供一种应用场景:在辅助驾驶或自动驾驶场景中,行驶车辆需要对周边的环境进行感知。为了能够保持安全的行车环境,行驶车辆需要了解周边车辆的状态信息,如速度、位置等。一方面,行驶车辆可通过安装在车辆上面的车辆传感器探测得到周边车辆的状态信息。另一方面,行驶车辆可以通过V2X的方式获取周边车辆的状态信息。之后,驾驶车辆基于获取到的周边环境的速度和距离等信息,结合自身车姿等相关信息,可以为辅助驾驶或自动驾驶的功能规划出可能的行驶路径,并结合车辆 动力学模型给出相应的控制命令,并交给执行器来执行,从而完成辅助驾驶和自动驾驶的功能。
在一种可能的方案中,车辆可周期性广播基础安全消息(basic safety message,BSM),将自身的状态信息告知其他车辆,其他车辆可以通过BSM消息可以获知相关车辆的状态信息,比如实时的位置、速度以及加速度等,从而通过上述信息可以进行动力学方案的考虑,进行路径规划和控制等。
其中,在对当前车辆进行路径规划和安全威胁分析等过程中,当前车辆除了需要使用环境中车辆的速度和位置等信息外,还需要获知环境中车辆的最大制动能力等其它相关信息。但在上述可能的方案中,BSM中仅仅包括当前车辆的实时速度和实时加速度等信息,并没有包括车辆能够支持的能力,特别是安全相关能力(比如最大加速度和最大制动能力)等,这会导致在进行安全威胁分析和/或路径规划的时候,无法准确的评估环境风险,从而导致潜在的安全隐患。
基于上述方案,本申请实施例提供一种通信方法及装置,该方法的原理为:第一终端设备获取周边终端设备(例如第二车辆)的能力信息,所述第一终端设备根据第二终端设备的能力信息,进行路径规划和/或安全威胁分析等相关的操作,从而准确的评估环境风险,满足安全驾驶的需求。
