(EN) DATA TRANSMISSION METHOD IN VEHICLE COMMUNICATION INTERFACE APPARATUS AND VEHICLE COMMUNICATION INTERFACE APPARATUS
Abstract
(EN)

Embodiments of the present invention relate to the field of vehicle diagnosis technologies, and specifically disclose a data transmission method in a vehicle communication interface apparatus and a vehicle communication interface apparatus. The vehicle communication interface apparatus includes a first controller and a second controller. The data transmission method includes: receiving, by the first controller, a diagnostic command sent by an upper computer, and storing the diagnostic command into a first queue; obtaining, by the second controller, the diagnostic command from the first queue, and sending the diagnostic command to an electronic control unit (ECU) in a vehicle connected to the vehicle communication interface apparatus; and receiving, by the second controller, diagnostic data from the ECU, and storing the diagnostic data into a second queue, to make the first controller obtain the diagnostic data from the second queue and send the diagnostic data to the upper computer. Through the foregoing technical solution, the embodiments of the present invention can respond to the diagnostic command and receive the diagnostic data simultaneously.
