Vehicle diagnosis method, joint and system

Abstract

The embodiment of the invention discloses a vehicle diagnosis method, joint and system; the method comprises the following steps: the diagnosis joint receives a plurality of diagnosis orders respectively sent by a plurality of diagnosis hosts, and stores the diagnosis orders to a data receive queue; the diagnosis joint extracts the plurality of diagnosis orders in sequence from the data receive queue, communicates and diagnoses the vehicle according to the diagnosis orders, obtains a plurality of diagnosis results in order, and stores the diagnosis results into a data transmit queue in sequence; the diagnosis joint respectively transmits the plurality of diagnosis results from the data transmit queue to the plurality of diagnosis hosts. The diagnosis joint is wirelessly connected with the plurality of diagnosis hosts in the same time, thus realizing the diagnosis mode using one diagnosis joint to match with the plurality of diagnosis hosts, allowing the diagnosis hosts to simultaneously diagnose the same vehicle, and improving the diagnosis efficiency.

Description

technical field [0001] The invention relates to the field of automobile diagnosis, in particular to an automobile diagnosis method, a diagnosis joint, and a diagnosis system. Background technique [0002] Automobile is the most familiar and common means of transportation for people, and it plays a very important role in people's life.
