Automobile instrument cluster testing method and system

Abstract

The invention discloses an automobile instrument cluster testing method and system, and the method comprises the steps: programming a signal, needing to be simulated, of each electronic control unit in an automobile through IF statements through script writing, so as to write the signals into a script; automatically generating a job file after writing is completed; and when a click instruction forthe job file is received, executing a corresponding instrument test, and generating a corresponding test result. According to the automobile instrument cluster testing method provided by the invention, a semi-automatic instrument test is realized, each ECU signal on the whole automobile can be automatically simulated and sent to during a bench test, the instrument performs corresponding responseafter receiving the signals, manual simulation sending of the signals one by one is not needed, the time is saved, the test period is shortened, when the alarm priority is measured, the environment ofthe whole automobile can be simulated more accurately, the alarm priority of the whole automobile is displayed, and the problem of priority disorder caused by personal errors is avoided.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and system for testing an automobile combination meter. Background technique [0002] With the rapid development of automobile intelligence and electrification, there are more and more control units on the car, and the functions are more and more complex. The vehicle dashboard provides the driver with the required operation according to the signals fed back by each electronic control unit (ECU). Parameter information and working status information of each system of the vehicle. [0003] Before the mass production of the whole vehicle, in order to ensure that the instrument can normally display the working status of each system of the vehicle, it is necessary to verify the full function of the instrument to ensure that its function is completely problem-free. At present, in the field of automotive electronic and electrical instrument testing, most of them use test to...
