Abstract

The invention provides a vehicle-mounted bus simulation model self-generating method and system. According to the vehicle-mounted bus simulation model self-generating method and system, a full-simulation or semi-physical simulation model is generated based on vehicle data information; and CANoe software-based simulation model or test model automatic generation is realized through steps such as electronic control module attribute definition, bus behavior logic strategy database entry and bus database file loading, and therefore, bus behavior full-simulation and bus semi-physical test environment construction can be realized. The system has the advantages of simple and convenient operation, fast script generation, stable performance, excellent operation, high extensibility and high flexibility. The system is provided with a comprehensive and extensible logical database and is suitable for all kinds of model detection of passenger vehicles; and the system is provided with an expert experience library, so that performance evaluation can be completed through direct or indirect information read service relationships.

Description

technical field [0001] The invention creates the field of vehicle simulation, and in particular relates to a method and system for self-generating a vehicle bus simulation model. Background technique [0002] At present, in the process of bus architecture development and physical testing of new models, there are mainly the following requirements: (1) Parametric evaluation of bus behavior architecture design. (2) When testing a single ECU / missing part of the ECU, simulate the bus behavior of the disconnected ECU to realize the integrity test of the bus behavior. (3) Indicative evaluation of the impact of gateway forwarding logic on bus behavior. At present, although the above requirements have been met, the customized simulation / test scripts for each model are basically written manually, with low efficiency, heavy workload, long cycle, and lack of consistent script design, so there is a certain risk of script writing errors. The comprehensiveness of the evaluation cannot be...
