Simulation testing method and device of whole vehicle electrical system

Abstract

The invention relates to a simulation testing method and device of a whole vehicle electrical system, and aims to solve the problems that in the prior art, the testing is incomplete and the testing cost is high due to the real object-based testing of the whole vehicle electrical system. According to the simulation testing method of the whole vehicle electrical system, the whole vehicle electricalsystem comprises a plurality of independent subsystems. The method comprises the steps of performing equivalent circuit simplification on each subsystem; classifying all parts; performing model building on the parts in each subsystem, and dividing part models of each subsystem into a plurality of part model libraries according to a classification result; assigning a value to each part model in thepart model libraries; establishing a plurality of model testing racks according to the classification result; and applying all the value-assigned part models in each type of the part model library tothe model testing rack of the corresponding type, and performing part model testing, subsystem model testing and system model testing.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a simulation test method and device for a complete vehicle electrical system. Background technique [0002] The electrical system test of the whole vehicle is generally carried out in the physical stage, and the correctness of the electrical system design is verified through a series of tests such as yellow board test, engine bench test, vehicle overload test, open circuit and short circuit test, ground loss and power loss test, etc. This traditional method consumes huge material costs and labor costs, and the test cycle is quite long. (Two rounds of bench tests for each model, 15 days per round, 4 people, the test cost and material cost add up to nearly 50,000. Each project costs 100,000 yuan, and 10 projects cost 1 million yuan a year. There is also an overheating test. The test cost for each project is 1 million yuan. 10 cars for each project are 10 million yuan, and 10 projects are ...
