The invention discloses a traffic data verification method, a traffic data broadcasting method and a traffic data broadcasting system. The method comprises the following steps: observing detection data of an associated electronic control unit associated with a behavior instruction and/or an electronic component associated with the behavior instruction according to the behavior instruction sent bythe electronic control unit, and generating observation data associated with the behavior instruction; and performing validity verification on the behavior instruction based on the observation data soas to verify the validity of the traffic data acquired from the electronic control unit according to the behavior instruction and broadcast to the peripheral vehicles; judging whether the detection data of the other electronic control unit is valid or not through the detection data of the other electronic control unit and/or the detection data of the other related electronic components, whether the other electronic control unit is attacked by a hacker or not can be judged through the method, and then the effectiveness of traffic data source verification is guaranteed. Through validity verification of the traffic data, the authenticity of the vehicle-vehicle communication message is improved, and the authenticity of road condition information transmission is ensured.
一种交通数据校验方法、交通数据广播方法及系统,根据电子控制单元发送的行为指令观测与行为指令关联的关联电子控制单元和/或与行为指令相关的电子元器件的检测数据,生成与行为指令关联的观测数据;基于观测数据对行为指令进行有效性校验,以对根据行为指令从电子控制单元获取的并向外围车辆广播的交通数据的有效性进行校验。通过其他电子控制单元的检测数据和/或其他相关电子元器件的检测数据来判断另一电子控制单元的检测数据是否有效,通过该方法还能判断该另一电子控制单元是否被黑客攻击,进而保证交通数据源头校验的有效性。通过对交通数据的有效性校验,提高车‑车通信消息的真实性,确保路况信息传递的真实性。
