Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] One, the design of the technical solution of the present invention

[0030] The present invention relates to a test system and method for the combination of automobile wind noise, fuel consumption and exhaust emissions. The testing method of emission data finally realizes that once one of the data (wind noise data or fuel consumption and exhaust emission data) is known, the other data (fuel consumption and exhaust emission data or wind noise data) can be estimated.

[0031] 2. Concrete implementation of the test method based on vehicle wind noise data and the test method process of fuel consumption and exhaust emission data

[0032] The automobile wind noise test method is firstly equipped with a wind noise test system, as attached figure 1 As shown, the system is mainly composed of American NI (National Instruments) data acquisition card, LabVIEW 2014 enginee...

Abstract

The invention discloses a system and a method for testing automobile air noise and fuel consumption and automobile exhaust emission. The system comprises US (national instruments) data acquisition card, LabVIEW 2014 engineering software, BSWAMPA466 model acoustic pressure meter, a vehicle-mounted tail gas detection device, a notebook computer and other equipment. According to the invention, the automobile wind noise test and the PEMS test are combined for the first time. Firstly, a vehicle-mounted emission testing system is built to obtain second-by-second automobile emission data, and a multi-element nonlinear data model with the wind-noise data acquired by the NI is then established. If one of the data (the air noise data or the fuel consumption and the tail gas emission data) is obtained, the other one data(fuel consumption and tail gas emission data or wind noise data) can be estimated.

Description

technical field [0001] The invention relates to a test system and method for combining wind noise, fuel consumption and exhaust emission of automobiles. Background technique [0002] According to statistics from the Traffic Management Bureau of the Ministry of Public Security, as of the end of 2016, the number of cars in the country has exceeded 194 million, that is to say, one out of seven people owns a car. For a large number of cars, its exhaust emissions and wind noise problems are enough to attract people's attention. Automobile emission test equipment (PEMS: PortableEmission Measurement System) is currently quite expensive, and the process of loading it on the car is also relatively complicated. The testing technology of automobile wind noise has been particularly mature, and all major automakers have related equipment and technology. At present, no one has done research on the relationship between wind noise and exhaust emissions. If a mathematical model between th...
