Suppose you have written a program on “how to add two numbers”. Now the input is the coding and the output is adding two numbers. That is the basic difference between MATLAB and Simulink. MATLAB is the programming language and Simulink is the output of the language. In this blog, we will identify the fuel economy model in MATLAB Simulink. But before that, let us get an idea about what MATLAB Simulink is and what the fuel economy model is.

MATLAB Simulink is a graphical programming environment for modelling, simulating and analysing dynamic systems. It allows users to design, simulate, and analyse systems using block diagrams, which are collections of blocks that represent different components of a system. The blocks can represent mathematical operations, physical systems, or even MATLAB code. Simulink is commonly used in the design and simulation of control systems, communication systems, and other engineering systems.

Understanding the fuel economy model

Fuel economy is a measure of how much fuel a vehicle consumes per unit distance travelled. A fuel economy model is a mathematical model that predicts the fuel consumption of a vehicle based on certain input variables. These input variables can include the vehicle’s speed, weight, engine size, and aerodynamic drag, as well as environmental factors such as temperature and altitude.

Fuel economy models can be used to estimate the fuel consumption of a vehicle under different operating conditions, and to evaluate the potential fuel savings of different design or operational changes. They can also be used to compare the fuel efficiency of different vehicles or technologies.

Fuel economy models can be developed using various methods, including experimental testing, simulation and data-driven approaches. They are commonly used in the automotive industry, transportation research, and environmental impact studies.

Identifying the fuel economy model in the MATLAB Simulink

In MATLAB Simulink, the “Fuel Economy” library provides a set of blocks that can be used to model the fuel consumption of a vehicle. This library includes blocks for modelling the engine, transmission, and other powertrain components, as well as blocks for modelling the vehicle’s dynamics, such as its speed and acceleration.

The library also includes a block called the “Fuel Consumption Block” which can be used to calculate the fuel consumption of the vehicle based on the input from other blocks in the model. This block can be configured to use different equations or data sets to model the fuel consumption, and it can output the fuel consumption as a function of time, distance, or other variables.

Simulink also provides a set of “Driveline” libraries which can be used to model the powertrain of the vehicle including the engine, transmission and other components. The library includes blocks for modelling the mechanical and thermal components of the engine, as well as the transmission and driveline. These blocks can be connected to other blocks in the model to simulate the behaviour of the entire powertrain.

The above-mentioned blocks can be combined to create a fuel economy model which can be used to predict the fuel consumption of a vehicle under different operating conditions and compare the fuel efficiency of different vehicles or technologies.
