Method and device for exhaust control of intelligent numerical control valve and system thereof

Abstract

The invention relates to a method and a device for exhaust control of an intelligent numerical control valve and a system thereof. The method comprises the steps of: setting the sensitiveness of an exhaust valve and the opening time of the exhaust valve in an exhaust system; acquiring the pressure value of an automobile exhaust pipe, and comparing the acquired pressure value of the automobile exhaust pipe with the set sensitiveness of the exhaust valve; judging if the pressure value of the automobile exhaust pipe in the preset time reaches the set sensitiveness of the exhaust valve, and generating an opening signal of the exhaust valve if the pressure value of the automobile exhaust pipe reaches the set sensitiveness of the exhaust valve; and sending the opening signal of the exhaust valve to an exhaust valve execution device, opening the automobile exhaust valve through the exhaust valve execution device, and controlling the opening time length of the automobile exhaust valve according to the opening signal of the exhaust valve and the opening time of the exhaust valve. The method can automatically adjust and control the exhaust state through acquiring and analyzing the pressure value of the exhaust pipe, so that the efficiency of the exhaust system is higher.

Description

technical field [0001] The invention relates to the field of automobile and vehicle exhaust control, in particular to an intelligent numerical control valve exhaust control method, an intelligent numerical control valve exhaust control device and an intelligent numerical control valve exhaust control system. Background technique [0002] Today in the 21st century, with the improvement of people's living standards, the popularization of cars (especially private cars) has become a trend. Under this trend, in order to pursue better performance of vehicles, many car owners will give One's own car is equipped with accessories with higher performance, and the exhaust system is one of them. In the prior art, the working modes adopted by the usual exhaust system are divided into two categories: the first category is uncontrollable, and the exhaust system Although the power has been greatly improved after the installation, the exhaust system is always open when the vehicle is running...

[0002] Today in the 21st century, with the improvement of people's living standards, the popularization of cars (especially private cars) has become a trend. Under this trend, in order to pursue better performance of vehicles, many car owners will give One's own car is equipped with accessories with higher performance, and the exhaust system is one of them. In the prior art, the working modes adopted by the usual exhaust system are divided into two categories: the first category is uncontrollable, and the exhaust system Although the power has been greatly improved after the installation, the exhaust system is always open when the vehicle is running because it cannot be controlled manually, resulting in a great waste of exhaust system efficiency at low speeds or complex road conditions. Exhaust systems with high performance usually have a lot of noise, which will affect other people's daily life; the second type is controllable but not adjustable. Although this type of exhaust system can be opened or closed artificially by the driver, the exhaust state usually not adjustable
