Embodiment approach

[0037] Virtual reality test is a test carried out in a virtual environment. The virtual test environment is based on the simulation test system developed by software engineers. The designer installs the test product (virtual prototype) in the test environment for testing, with the help of interactive technology and test analysis technology , so that the designer can evaluate or experience the operating performance of the product during the design stage. In other words, the virtual experiment is to use software to replace part or all of the hardware in the computer system to establish various virtual experimental environments, so that the experimenter can complete various predetermined experimental items as in the real environment, so that all The experimental effect obtained is close to or equivalent to the effect obtained in the real environment. Therefore, the implementation of a virtual test system generally requires the following four steps:

[0038] 1. Establishment of v...

Abstract

The invention discloses an entire car road virtual testing system, the core of which is a three dimensional interactive computer and the user operation interface thereof. The testing system is disposed with a testing parameter loading module for loading road spectrum loading to the teste vehicle model and test road model; the testing system is disposed with a virtual testing module including peripheral auxiliary equipments; and the testing system is also provided with a estimation module. The invention further discloses a testing method adopted in the testing system. Adopting the technical scheme in the invention can greatly reduce prototype engine test times, shortens new product test period, and reduces actual test cost; applying the virtual test technology in complex product exploitation can realize the inter information feedback between the designer and product user in design phase; and replacing actual test by the virtual test can eliminate the restriction of place, time and frequency to the test, and can recover and repeat the test process.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing technology, and relates to a test system for a complete vehicle. More specifically, the invention relates to a virtual test system for a complete vehicle road. In addition, the present invention also relates to the test method adopted by the test system. Background technique [0002] As an important manufacturing industry, the automobile industry is characterized by large output, many varieties, complex product use conditions, high requirements on product performance, life and cost, and involves a wide range of technical fields, and many theoretical issues are not enough. Sufficiently, many design problems cannot establish mathematical models based on existing theories and make reliable predictions. Only through the vehicle road test, to obtain the necessary technical parameters. Therefore, the vehicle road test has become one of the most critical links in the design and develop...
