Domain controller test system

Abstract

The invention provides a domain controller test system, which comprises a test device and a domain controller, and is characterized in that the test device comprises a task scheduling module, the domain controller comprises a task execution module, and the task scheduling module is used for sending a test instruction to the domain controller; the task execution module is used for analyzing the test instruction, determining a to-be-tested link and a test case according to the test instruction, sending an action instruction to an external device connected with the to-be-tested link according to the test case, obtaining an execution result of the external device, determining a detection result of the to-be-tested link according to the execution result, and sending the detection result to the to-be-tested link. According to the domain controller testing system provided by the invention, the testing device only needs to send the testing instruction to the domain controller, the domain controller can automatically complete link detection, a testing system for detecting the link does not need to be specially built, and the testing time and cost are saved.

Description

technical field [0001] The invention relates to the technical field of automobile equipment testing, in particular to a domain controller testing system. Background technique [0002] With the increasing degree of automotive electronics, the electronic control unit (ECU) has become one of the most common components in the car, and dozens or even hundreds of electronic control units have proposed the traditional automotive electronic and electrical distributed architecture. In order to meet the challenges, a domain-based automotive domain control unit (DCU) integrated architecture came into being. One of them is the intelligent cockpit domain controller, which utilizes powerful multi-core CPU / GPU chips to centrally control panoramic surround view. (AVM), in-vehicle data terminal (T-Box), in-vehicle infotainment (IVI) and driver monitoring (DMS) systems to meet the increasingly intelligent and humanized interaction / entertainment needs. [0003] In order to ensure the reliabil...

Problems solved by technology

[0003] In order to ensure the reliability of the smart cockpit domain controller and its external links, a large number of tests need to be done. Under the guidance of the "new four modernizations" in the automotive industry, the smart cockpit domain controller is no longer limited to multi-screen interconnection (LCD Instrument + HUD + central control screen + rear entertainment) interactive experience, augmented reality head-up display, driving monitoring, streaming media rearview mirror, transparent A-pillar, gesture recognition, face recognition, sound source positioning, fabric interaction, holographic image The multi-channel integration and interaction methods are also developing rapidly. The rich cockpit functions and the differentiated requirements of different models lead to a variety of cockpit system configuration solutions, which also brings more challenges to the test.

[0004] The traditional test methods for the smart cockpit domain controller and its external links include real vehicle testing and testing based on the controller area network (CAN) bus, but these two methods are more effective in testing the smart cockpit domain controller and its external links. During the test process, additional instruments and meters are required to build the test system, which is time-consuming and labor-intensive, and there are supply chain risks
