The invention discloses an in-vehicle wireless communication system which comprises a vehicle body domain controller which is connected with other controllers through wireless communication. After the vehicle is powered on and runs, the vehicle body domain controller and other controllers confirm to establish communication in a sequential polling mode; when a substantial communication demand exists, the vehicle body domain controller sends the same control demand to the target controller at different frequencies for multiple times, and each controller determines whether the control demand needs to be executed by itself and whether the control demand is a safe request by judging a message; if the target controller needs to execute by itself and the request is safe, the target controller continuously sends the execution state of the current instruction at different frequencies for multiple times in the execution process and feeds back the execution state to the vehicle body domain controller, and the vehicle body domain controller judges and memorizes the current working state of the system after receiving the information and provides a basis for next execution. According to the system, the constraint of wire harness design, deployment and maintenance on innovative vehicle-mounted application is broken, cost is reduced, efficiency is improved, and novel vehicle-mounted application and market are further catalyzed.

    本发明公开一种车内无线通讯系统,该系统包括车身域控制器,其通过无线通讯与其他控制器连接;车辆上电运行以后,车身域控制器与其他控制器通过顺序轮询的形式确认建立通讯;当有实质通讯需求时,车身域控制器分多次以不同频率发送同一控制需求给到目标控制器,各控制器通过判断报文确认是否需要自己执行以及是否是安全的请求;若需要自己执行且请求是安全的,则目标控制器在执行过程当中持续分多次以不同频率发送当前指令的执行状态,反馈给车身域控制器,车身域控制器收到信息后判断并记忆当前该系统的工作状态,并为下次执行提供依据。本系统打破了线束设计、部署、维护对于创新车载应用的束缚,降本增效并进一步催化新型的车载应用和市场。
