Abstract

The invention provides a method for benchmarking an engine stand based on whole vehicle simulation operation, which specifically comprises the following steps: (1) collecting data of a disclosed benchmarking engine and a carrying vehicle model, and establishing basic information of a database; (2) collecting OBD data and electrical signals of the benchmarking engine and the carrying vehicle to obtain the signal type, waveform, speed and frequency relationship; (3) removing the engine from the whole vehicle, separating the engine from a gearbox, and building a benchmarking test stand system; and (4) running the stand system to enable the whole vehicle simulation operation function to ensure the normal ignition operation of the benchmarking engine. The method for benchmarking the engine stand based on the vehicle simulation operation according to the invention effectively solves the problem that various benchmarking engines cannot be normally ignited on the stand, and ensures successfulimplementation of the benchmarking test of the engine stand. The method of the present invention is reliable and effective, and has wide versatility.

Description

technical field [0001] The invention belongs to the field of automobile testing of engine bench testing, in particular to an engine bench benchmarking method based on the simulated operation of a whole vehicle. Background technique [0002] Benchmarking test is a commonly used technical method in the process of automobile performance development. Through this test, various performance data of competing models or high-performance models can be obtained, which can be used for formulating performance indicators, performance control reference and performance horizontal evaluation of developed models. The benchmarking test of the whole vehicle is relatively easy. It does not need to make special changes to the vehicle, and the test can be carried out directly according to the test specifications. However, the benchmarking test of the engine, which is the core component of the vehicle, is very difficult. [0003] The engine test test needs to be carried out on a special bench, and...
