The embodiment of the invention relates to the technical field of vehicle diagnosis, and particularly discloses a data transmission method in a vehicle communication interface device and the vehicle communication interface device. The vehicle communication interface device comprises a first controller and a second controller, and the data transmission method comprises the steps that the first controller receives a diagnosis command sent by an upper computer and stores the diagnosis command to a first queue; the second controller obtains the diagnosis command from the first queue and sends the diagnosis command to an electronic control unit in the vehicle connected with the vehicle communication interface device; and the second controller receives the diagnosis data from the electronic control unit and stores the diagnosis data to the second queue, so that the first controller obtains the diagnosis data from the second queue and sends the diagnosis data to the upper computer. Through the technical scheme, the embodiment of the invention can respond to the diagnosis command and receive the diagnosis data at the same time.
本发明实施例涉及车辆诊断技术领域,具体公开了一种车辆通信接口装置中的数据传输方法及车辆通信接口装置。其中,车辆通信接口装置包括第一控制器、第二控制器,数据传输方法包括:第一控制器接收上位机发送的诊断命令,并将诊断命令储存至第一队列;第二控制器从所述第一队列中获取诊断命令,并将诊断命令发送至与车辆通信接口装置连接的车辆中的电子控制单元;第二控制器接收来自电子控制单元的诊断数据,并将诊断数据储存至第二队列,以使第一控制器从第二队列获取诊断数据,并将诊断数据发送至上位机。通过上述技术方案,本发明实施例能同时响应诊断命令并接收诊断数据。
