Vehicle dynamics

Vehicle dynamics refers to the dynamics of vehicles, here assumed to be ground vehicles. Vehicle dynamics is a part of engineering primarily based on classical mechanics.

This article applies primarily to automobiles. For single-track vehicles, specifically the two-wheeled variety, see bicycle and motorcycle dynamics. For aircraft, see flight dynamics. For watercraft see Hydrodynamics.

Components, attributes or aspects of vehicle dynamics include:

Some attributes or aspects of vehicle dynamics are purely aerodynamic. These include:

Some attributes or aspects of vehicle dynamics are purely geometric. These include:

Some attributes or aspects of vehicle dynamics are purely due to mass and its distribution. These include:

Some attributes or aspects of vehicle dynamics are purely dynamic. These include:

Some attributes or aspects of vehicle dynamics can be attributed directly to the tires. These include:

Some attributes or aspects of vehicle dynamics can be attributed directly to the roads on which they travel. These include:

Driving techniques which relate to, or improve the stability of vehicle dynamics include:

The dynamic behavior of vehicles can be analysed in several different ways. This can be as straightforward as a simple spring mass system, through a three-degree of freedom (DoF) bicycle model, to a large degree of complexity using a multibody system simulation package such as MSC ADAMS or Modelica. As computers have gotten faster, and software user interfaces have improved, commercial packages such as CarSim have become widely used in industry for rapidly evaluating hundreds of test conditions much faster than real time. Vehicle models are often simulated with advanced controller designs provided as software in the loop (SIL) with controller design software such as Simulink, or with physical hardware in the loop (HIL).
