Black box testing method and system for functions of electronic body control module of automobile

Abstract

The invention discloses a black box testing method and a system for functions of an electronic body control module of an automobile. The system comprises a PC (Personal Computer), an interface board card and a connecting box, wherein the PC is connected with the connecting box; the connecting box is communicated with the body control module of the automobile; and the PC is connected with the body control module of the automobile by the interface board card. The method and the system provide a method guide for the design of testing cases of the control module and ensure the testing integrity. As the testing cases are designed based on a state transition table, each state and state transition of the control module are covered by testing, and the testing integrity is ensured. With the adoption of enumeration and testing of conflict events, each state and state transition of the control module are covered by the testing even when multiple events happen simultaneously.

Description

technical field [0001] The invention specifically relates to a black-box testing method and system for the function of an electronic controller of an automobile body. Background technique [0002] More and more electronic control units are used in automobiles to control mechanical and physical components to achieve the goals of environmental protection, driving safety, comfort and convenience. The body electronic controller is the most common controller on the car, which controls the body components, provides safety alarms and friendly human-vehicle interaction functions. For different brands of cars, the scope definition of body control functions and the definition of each function are often not exactly the same. Generally speaking, the body electronic controller mainly includes the following control functions: centrally controlled door locks, exterior lights, interior lights, wipers, anti-theft alarms, remote control and window lifts, etc. [0003] There are three ways t...

Problems solved by technology

However, there are several problems in using these platforms to build test systems: First, these platforms cannot replace the design process of test cases, and they do not provide guidance on how to design test cases and how to ensure test integrity; secondly, the equipment costs of these platforms High, and all have restrictions on usage rights, usually bound to a specific PC, it is difficult to carry out multi-user parallel development, and it is also difficult to transplant; finally, these platforms have complex functions and complex operations, and what we want is only It is a test function and does not require other functions
