Abstract

The invention provides an automobile decoder and an automotive type recognition method thereof. The method includes the steps: the automobile decoder establishes diagnosis communication connection with an electronic control unit of a current automobile through a diagnosis port of the automobile decoder; the automobile decoder acquires feature information of the current automobile by means of diagnosis communication connection, and feature information of various types of automobiles is stored in the automobile decoder; the automobile decoder compares the feature information of the current automobile with the stored feature information of various types of automobiles and recognizes the type of the current automobile according to comparison results. After the decoder is mounted on a corresponding type of automobile by a user, the decoder starts self-learning during electrification for initialization for each time so as to acquire automobile information to automatically recognize various automobile types, and the whole process is simple, quick and effective.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile decoder and a method for identifying vehicle types thereof. Background technique [0002] With the rapid development of automotive electronics technology, in-vehicle information communication and infotainment systems are gradually becoming hot spots pursued by auto manufacturers. The bus signal and diagnostic information are indispensable for the realization of in-vehicle entertainment information, which brings certain challenges to the popular car decoders in the aftermarket. [0003] At present, most of the decoders on the market are only limited to OBD (On-Board Automatic Diagnosis System) information, or only limited to decoding information of a certain model. Because the in-vehicle networks of different models are different, their bus databases and diagnostic databases are also different, so the decoder can only be developed independently for a certain mod...
