Problems solved by technology

[0003] The purpose of the present invention is to solve the problem of relative wind force in the wind-making system of the existing simulated experimental cabin, which only considers the speed of the wind itself and does not combine the speed of the vehicle under actual driving conditions, and realizes a vehicle speed that can be intuitively displayed. The relative wind speed between the wind speed and the test system for the stability of the vehicle

Abstract

An all-weather environment simulation system for vehicle testing comprises a sunshine simulation system, a rain simulation system, a wind creating system, an exhaust emission treatment system and a testing chamber. The wind creating system comprises multiple air outlets and four groups of blowers, the air outlets are uniformly distributed in the four side walls of the testing chamber, the air outlets formed in the four walls of the testing chamber are connected with the blowers respectively, and the blowers are connected with control units respectively. Accordingly, various weather conditions such as temperature, humidity, sunshine and rain can be simulated, the wind speeds of the front wall, the rear wall, the left wall and the right wall can be controlled, the influence of the wind speeds in actual vehicle operation is fit, the road test frequency is greatly reduced, and the cost is greatly lowered.

Description

technical field [0001] The invention relates to a test system for vehicle performance, in particular to an all-weather environment simulation system for vehicle test. Background technique [0002] At present, in the process of automobile research and development, it is necessary to carry out simulated monitoring of the new automobile developed in an all-weather environment in the stop state and running state, so as to understand the performance of the automobile in all aspects. The most common test method is to test on the real road. However, the road test is greatly affected by time and place, the environmental factors are not easy to control, and the repeatability is not good. It is impossible to conduct in-depth research on the vehicle and subsystem technology, and it is difficult to provide the necessary technical reserves for newly developed vehicles. Therefore, with the rapid development of computers and related technologies, people have gained more and more benefits f...
