Abstract

The invention provides a diesel engine electronic control system CAN bus simulation platform comprising a computer simulation terminal and a CAN interface card, wherein database editing software and bus network simulation analysis software are installed on the computer simulation terminal. According to the platform provided by the invention, a CAN bus communication environment between a diesel engine electronic control system and a whole vehicle system can be simulated, the CAN bus communication design, simulation verification and communication test taking the diesel engine electronic controlsystem as a core are completed, the test of a network state between the electronic control system and other CAN bus nodes is brought to the linked test of the whole vehicle system, a communication fault is positioned during a development stage, an application risk is effectively avoided, and the development time and cost are saved.

Description

technical field [0001] The invention belongs to the technical field of diesel engine testing, and in particular relates to a CAN bus simulation platform of a diesel engine electric control system and a testing method thereof. Background technique [0002] The diesel engine electronic control system is a system with very complex functions. As a core subsystem, it exists in the vehicle network, shares information with the vehicle electrical system and propulsion system, and exchanges data in real time. CAN bus has become an important means of vehicle networked comprehensive control because of its advantages of stability and reliability, simple connection, and low implementation cost. The electronic control system also uses CAN bus communication with the requirements of the vehicle system. [0003] At present, in the CAN bus communication design process of the electronic control system, the communication code is mainly written manually, and the point-to-point data sending and r...
