Vehicle emission model modeling method suitable for intelligent networked vehicle emission control

Abstract

The invention discloses a vehicle emission model modeling method suitable for intelligent network connection vehicle emission control, and belongs to the technical field of intelligent control. The invention aims at providing the vehicle emission model modeling method suitable for intelligent network connection vehicle emission control, which is used for connecting a vehicle with an engine throughdriving power and is suitable for controlling different control targets such as oil consumption and emission of the vehicle in an intelligent network connection environment. The method comprises thesteps of an engine rotating speed module (1), a vehicle power module (2), a fuel consumption rate module (3) and an emission module (4). From the perspective of an upper-layer vehicle, the vehicle isassociated with an engine through driving power according to the state of the vehicle, an engine fuel consumption rate model is established according to the power, and then a linear model of the fuelconsumption rate and emission is fitted according to data. The model established through adoption of the modeling method is simple and high in accuracy, and the modeling method is suitable for being applied to control over different control targets such as oil consumption and emission of the vehicle in the intelligent networking environment.

Description

Problems solved by technology

However, when using intelligent traffic information to plan and control vehicles, the traditional control-oriented vehicle emission model stays at the engine level, and the external performance of the vehicle is speed, acceleration, and gear. It is speed or acceleration control, so the traditional modeling method lacks the combination of the underlying engine and the upper vehicle, and is not suitable for optimal control of vehicles in an intelligent networking environment.

In addition, the traditional emission modeling is a partial differential equation of chemical reaction and thermal energy reaction, which has a strong nonlinear and multivariable coupling relationship, which is not suitable for subsequent controller design or optimization planning
