Title:
VEHICLE DIAGNOSTIC METHOD, DEVICE, APPARATUS, AND SYSTEM, AND CONNECTION DIAGNOSTIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/134706
Kind Code:
A1
Abstract:
Embodiments of the present invention relate to a vehicle diagnostic method, device, apparatus, and system, and a connection diagnostic apparatus. The device comprises: a first interface interfacing module, configured to read a user operation on the interface, and convert the operation into a corresponding diagnostic instruction; a first protocol conversion module, configured to convert the diagnostic instruction into standard transmission data corresponding to the diagnostic instruction; and a first software interfacing module, configured to send the standard transmission data corresponding to the diagnostic instruction via a first communication unit. In the embodiments of the present invention, protocol conversion between a physical layer and a data link layer that consumes memory resources and processor resources is entirely or partially run on a vehicle diagnostic apparatus, such that a connection diagnostic apparatus only needs to run a part of the protocol conversion between the physical layer and the data link layer or does not need to run the protocol conversion between the physical layer and the data link layer. Thus, hardware performance requirements for the connection diagnostic apparatus are decreased, and hardware costs of the connection diagnostic apparatus are reduced.
