Abstract

The invention provides an exhaust noise regulating system, an exhaust noise regulating method and a vehicle. The exhaust noise regulating system is applicable to an automatic transmission vehicle with an S gear mode, and comprises a silencer, a control valve and a control unit, wherein the silencer is arranged in an exhaust system and comprises a silencer body, a gas inlet pipe component and an exhaust tail pipe; the gas inlet pipe component is arranged at the gas inlet end of the silencer body; the exhaust tail pipe is arranged at the gas outlet end of the silencer body; the control valve is arranged on the gas inlet pipe component; and the control unit is used for controlling both the opening of the control valve and the gas circulation section area of the gas inlet pipe component and regulating the noise of the exhaust tail pipe and is connected with the control valve. According to the exhaust noise regulating system provided by the invention, the valve opening of the control valve on the exhaust pipe component can be controlled through the control unit, so that the regulation of the gas circulation section area is realized to regulate the noise characteristic of the exhaust tail pipe in a moving mode and improve the roar and the growl of the tail pipe and the subjective feeling of a driver.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an exhaust noise adjustment system, an exhaust noise adjustment method and a vehicle. Background technique [0002] At present, many automatic transmission models on the market have sports mode (S mode), which can bring drivers a more intense driving experience (low gear, high speed, stronger power output), and is popular with some special driving habits. The driver's favorite, but in this mode, the exhaust noise of the vehicle has not been adjusted to the sports mode, so the driver's subjective experience (exhaust noise hearing and NVH experience) in the sports mode is not strong enough. [0003] The muffler is installed in the exhaust system of the vehicle to reduce the noise of the exhaust system. The muffler usually includes a muffler body, an air intake pipe installed at the inlet end of the muffler body, and an exhaust tailpipe installed at the outlet end of the muffle...
