The invention discloses a vehicle exhaust pipe valve control method, a vehicle comprises a first exhaust pipe, a second exhaust pipe and a silencing structure, the first exhaust pipe is provided with a valve, and the second exhaust pipe is connected with the silencing structure; the method comprises the steps of determining an area where a vehicle is located by obtaining a geographic position of the vehicle, obtaining a linear distance between the vehicle and a noise reduction point in a first noise adjustment area range when the vehicle is in the first noise adjustment area range, and adjusting the noise reduction point in the first noise adjustment area range when the linear distance is not greater than a preset first distance threshold value. And when the linear distance is larger than a preset first distance threshold value, the opening degree of a valve of a first exhaust pipe in the vehicle is controlled to be a preset first opening degree, and when the linear distance is larger than the preset first distance threshold value, the opening degree of the valve is controlled to be a preset second opening degree. The invention further discloses a vehicle exhaust pipe valve control device, system and equipment. According to the embodiment, the opening degree of the valve of the vehicle exhaust pipe can be adjusted according to the vehicle position, then the exhaust noise of the vehicle is controlled, and the driving experience feeling is improved.
Description
technical field [0001] The present invention relates to the technical field of automobile control, and in particular, to a method, device, system and equipment for controlling a vehicle exhaust pipe valve. Background technique [0002] The vehicle exhaust system is an important part of the car. The exhaust system exhausts the exhaust gas and also brings the combustion noise to the rear of the vehicle, producing high-order noise and friction noise with a high sound pressure level at the rear. With the improvement of people's living standards, People's requirements for the whole vehicle have changed from the original means of transportation to a comfortable household necessities, so in addition to the stricter requirements for the power of the vehicle, the noise requirements for the vehicle have also increased. In areas that require a quiet environment, the exhaust noise should be kept low to avoid noise pollution, while in the suburbs and other areas, it is suitable to increa...
