example 1

[0021] refer to figure 1 As shown, the vehicle test system based on OSEC network management includes CANoe software, including human-computer interaction interface, OSEC network management mechanism processing module; CAN transceiver; gateway; two CAN buses, including body CAN bus and power CAN bus , where the controller is a controller with network management functions. Described CANoe software is used to provide the programming environment of programming language CAPL; Utilize the Panel plug-in in CANoe to carry out editing control and information display interface during man-machine interaction interface; end.

[0022] Such as figure 2 The schematic diagram of the network constructed by ECU nodes shown is a logical ring token network structure diagram constructed by ECU nodes according to OSEC network management standards. Each ECU with OSEC network management functions needs to construct a logical ring token, and then according to each The number of each ECU node, that...

Abstract

Provided in the invention is an OSEC-network-management-based complete vehicle test system comprising a man-machine interaction interface, a CAN transceiver, a gateway, and a complete vehicle controller. The system is characterized in that an OSEC network management mechanism processing module that for unified management of sleep waking up of a complete vehicle ECU is connected between the human-machine interaction interface and the CAN transceiver. The OSEC network management mechanism processing module consists of a processing module for monitoring OSEC network management message, a processing module for monitoring OSEC network management message group ring information, a processing module for determining whether a time parameter of an OSEC network management message meets a standard, and a processing module for generating a test report. The complete vehicle test system has the following beneficial effects: with the programmable characteristic of CANoe integration, integration of a testing system of complete vehicle OSEC network management is realized; automatic testing of the complete vehicle OSEC network management is realized; a problem of low manual testing efficiency is solved; the testing cost is lowered; and the test efficiency is high and the testing period is short.

Description

technical field [0001] The invention relates to the field of automotive electronic CAN (Controller Area Network) network communication, and is a vehicle test system based on OSEC (Open Systems and the Corresponding Interfaces for Automotive Electronics) network management. Background technique [0002] With the continuous development of automotive technology, more ECUs (Electric Control Units) are required to be applied to the body network. Due to the demand for functions, most ECUs are powered by constant power (CL30 power). These ECUs need to enter a low power consumption state when they are not working, otherwise it will cause unnecessary waste of power when the vehicle is not working, thereby shortening the power supply time of the power supply battery. Based on the above reasons, it is necessary to introduce the OSEC network management system in the vehicle network. Its main function is to negotiate the sleep and wake-up of each ECU in the CAN network, provide a standa...
