Abstract: Technical solutions are described for facilitating intra-vehicle wireless communication among a plurality of electronic control units. An example method includes determining, by a first electronic control unit in a vehicle, a wait-time for a message, which is to be transmitted to a second electronic control unit in the vehicle via a wireless channel. The first electronic control unit executes a first availability-check, by determining availability of the wireless channel. In response to the first availability-check indicating that the wireless communication channel is available, the method includes delaying transmission of the message by the wait-time. The method also includes executing, by the first electronic control unit, after passage of the wait-time, a second availability-check. In response to the second availability-check indicating that the wireless communication channel is still available, the method includes transmitting the message for receipt by the second electronic control unit.

Abstract translation: 描述了用于促进多个电子控制单元之间的车内无线通信的技术方案。 一种示例性方法包括通过车辆中的第一电子控制单元通过无线信道来确定要发送到车辆中的第二电子控制单元的消息的等待时间。 第一电子控制单元通过确定无线信道的可用性来执行第一可用性检查。 响应于指示无线通信信道可用的第一可用性检查，该方法包括延迟消息的等待时间的传输。 该方法还包括由第一电子控制单元执行等待时间之后的第二可用性检查。 响应于指示无线通信信道仍然可用的第二可用性检查，该方法包括发送消息以供第二电子控制单元接收。
