Abstract

The invention provides an automated test system and test method based on AUTOSAR network management, including a PC host, an oscilloscope, a program-controlled regulated power supply, a bus simulation acquisition tool VN1640A, a relay board, and a regulated power supply; KL31, KL30, KL15 is respectively connected to the relay board, the CANH and CANL of the ECU under test are respectively connected to the oscilloscope and the DB9 of one CAN channel of the bus simulation acquisition tool VN1640A; the DB9 of the other CAN channel of the bus simulation acquisition tool VN1640A is connected to the relay board; The positive and negative wiring harnesses of the piezoelectric power supply are connected to the relay board; the positive and negative wiring harnesses of the regulated power supply are connected to the relay board; the bus acquisition simulation tool VN1640A, the program-controlled regulated power supply and the oscilloscope are respectively connected to the PC; There are upper-level software and lower-level software running, and the upper-level software is an automated test operating system for managing the test process; the lower-level software includes test sequence engineering and equipment program-controlled drive instruction library. The invention can realize efficient testing with high real-time performance and rapid execution.

Description

technical field [0001] The invention belongs to the field of vehicle bus testing, and in particular relates to an automatic testing system and testing method based on AUTOSAR network management. Background technique [0002] At present, with the development of automotive electronic control modules (ECUs) and the urgent requirements for energy saving and emission reduction of vehicles, in the design and development of vehicle electronic and electrical architectures, the sleep and wake-up strategy of vehicle ECUs, that is, network management strategies, directly affects static power consumption. A series of problems such as the size, how to ensure the normal execution of the function of the ECU when the power-on working time of each partner node is unknown. In order to ensure that each ECU can timely and correctly implement the sleep wake-up strategy and send relevant status messages and signals, it is necessary to complete the test and verification of the ECUs participating i...
