Embodiment Construction

[0029] As mentioned in the background technology, the vehicle test method for the engine in the prior art requires vehicle resources and test road or drum equipment, and the test cost is high; the control of test conditions is not accurate enough and the repeatability is poor; the measurement of engine-related environmental parameters is inconvenient And the number is limited; drivers and test personnel are required to operate, the automation level is low, and it is greatly affected by human factors such as drivers, and the test quality and efficiency are not high enough.

[0030] In view of the technical problems described above, the embodiment of the present invention proposes a test method for a complete engine vehicle, which can control and generate the environmental parameters of the engine based on the set test data; A test environment, the test environment is used to simulate the functions of other equipment running in conjunction with the engine; thus, by generating a t...

Abstract

The invention relates to a method and device for testing an engine in a complete vehicle and an engine bench. The method for testing an engine in a complete vehicle comprises the steps of controllingto generate environmental parameters of the engine according to set test data; generating a test environment of the engine in the complete vehicle according to the environmental parameters, wherein the test environment is used for simulating functions of other equipment matched with the operation of the engine; and controlling the engine to operate in the test environment based on the set test data. The technical scheme reduces the cost of testing the engine in the complete vehicle, and improves the test quality and efficiency at the same time.

Description

technical field [0001] The invention relates to an engine bench test technology, in particular to an engine vehicle test method, device and engine bench. Background technique [0002] In the later stage of development, the engine needs to be loaded on the whole vehicle for a series of engine vehicle tests, mainly including durability, emission and fuel consumption tests. This test is completed on the vehicle road or drum, and needs to be repeated many times. [0003] However, the vehicle test method for the engine in the prior art requires vehicle resources and test road or drum equipment, and the test cost is high; the control of the test conditions is not accurate enough and the repeatability is poor; the measurement of the relevant environmental parameters of the engine is inconvenient and the number is limited; The driver and test personnel operate, the automation level is low, and it is greatly affected by human factors such as the driver, resulting in inaccurate test r...
