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.
(FR) Le mode de réalisation de la présente invention appartient au domaine technique du diagnostic de véhicule. L'invention concerne spécifiquement un procédé de transmission de données dans un appareil d'interface de communication de véhicule, et un appareil d'interface de communication de véhicule. L'appareil d'interface de communication de véhicule comprend un premier dispositif de commande et un second dispositif de commande. Le procédé de transmission de données comprend : un premier dispositif de commande recevant une instruction de diagnostic envoyée par un ordinateur supérieur, et stockant l'instruction de diagnostic dans une première file d'attente ; un second dispositif de commande acquérant l'instruction de diagnostic à partir de la première file d'attente, et envoyant l'instruction de diagnostic à une unité de commande électronique dans un véhicule connecté à un appareil d'interface de communication de véhicule ; et le second dispositif de commande recevant des données de diagnostic provenant de l'unité de commande électronique, et stockant les données de diagnostic dans une seconde file d'attente, de telle sorte que le premier dispositif de commande acquiert les données de diagnostic à partir de la seconde file d'attente, et envoie les données de diagnostic à l'ordinateur supérieur. À l'aide de la solution technique précitée, le mode de réalisation de la présente invention peut répondre à l'instruction de diagnostic et recevoir simultanément les données de diagnostic.
