Abstract
(EN)
The embodiment of the invention relates to the technical field of vehicle diagnosis, and specifically discloses a data transmission method in a vehicle communication interface device, and the vehiclecommunication interface device. The vehicle communication interface device comprises a first controller and a second controller. The data transmission method comprises the following steps: the first controller receives a diagnostic command sent by an upper computer, and stores the diagnostic command in a first queue; the second controller obtains the diagnostic command from the first queue and sends the diagnostic command to an electronic control unit in a vehicle connected with the vehicle communication interface device; and the second controller receives diagnostic data from the electronic control unit and stores the diagnostic data in a second queue, so that the first controller acquires the diagnostic data from the second queue and sends the diagnostic data to the upper computer. Through the above technical scheme, by adoption of the data transmission method provided by the embodiment of the invention, the diagnostic command can be simultaneously responded to, and the diagnostic data are received.
