Abstract

The embodiment of the invention relate to a method and device for establishing logical channels, and a vehicle communication interface (VCI). The method comprises receiving at least two first instructions sent by a vehicle diagnostic device, wherein the first instructions are used for instructing the vehicle diagnostic device to establish a connection to the electronic control unit (ECU) of the vehicle; establishing at least two logical channels according to the at least two first instructions, wherein the first instructions correspond to the logical channels one by one, the logical channels are used for transmitting the data between the vehicle diagnostic device and the ECU. The embodiment of the present invention establishes the at least two logical channels for transmitting the data between the vehicle diagnostic device and the ECU in accordance with the at least two first instructions so as to form a plurality of channels for accessing each ECUs. Through the at least two logical channels, the vehicle diagnostic device can simultaneously get access to at least two ECUs, thereby improving diagnostic efficiency.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of automobile diagnosis, and in particular to a method and device for establishing a logical channel and a vehicle communication interface VCI. Background technique [0002] At present, the automotive diagnostic system for detecting vehicle faults and performance is more and more widely used. It mainly connects the automotive network and the diagnostic software in the automotive diagnostic equipment through the automotive communication interface VCI, and uses the diagnostic software to control the electronic control unit (Electronic Control Unit) in the automotive network. , ECU) for diagnosis. At present, automobiles rely more and more on ECUs. A car can have as few as a dozen ECUs, and as many as dozens or hundreds of ECUs. [0003] During the process of realizing the present invention, the inventors found that there are at least the following problems in the related art: the cur...
