Under the environment with increasingly severe environmental protection, not only the automobile discharges harmful gases to pollute the environment, but also the noise pollution of the automobile is an important factor for the automobile to influence the environment. One of the important acoustic indicators for measuring the influence of the running of the automobile on the surrounding environment is the noise outside the automobile when the automobile runs in an accelerated manner. The external noise of the automobile during accelerated running is a mandatory detection item of the state for the newly delivered automobile, has a certain limit value, and if the produced automobile cannot be lower than the limit value, legal sales and production permission cannot be obtained. Therefore, the vehicle exterior noise detection item is particularly important for the whole vehicle factory.
At present, new energy automobiles in China are rapidly developed. Besides the traditional middle and large-sized whole vehicle manufacturing enterprises, emerging internet vehicle enterprises are briskly rising. Wherein, emerging automobile enterprises are basically producing new energy automobiles, and most of them are pure electric vehicles powered by lithium batteries. The electric vehicle has the advantages of environmental protection, comfort, quick acceleration and the like. However, the acceleration of the accelerator pedal during full-throttle acceleration greatly exceeds the acceleration specified in the new national standard GB1495-2020 limit value and measuring method for the noise outside the accelerated running vehicle of the automobile which is issued due to the acceleration characteristic formed by the motor drive. This results in the test conditions not completely meeting the legislative requirements during the test of the entire vehicle. In fact, the tires may have significant slip, so that the measured noise does not truly reflect the off-board noise conditions of conventional acceleration. Therefore, a tester needs a device capable of limiting the accelerator pedal of the automobile, so that the opening degree of the accelerator pedal during automobile testing is moderate, the acceleration accords with the regulation, and the testing result is more reasonable.
