Modern mobile phones with advanced functionality, known as smartphones, have many applications. A triaxial accelerometer is used to determine the current position of the smartphone in space and therefore the screen orientation. It is known that accelerometers are used to determine important operational properties of vehicles, such as dynamics and acceleration. In this regard, the purpose of this paper is to study the possibility of using a smartphone to measure the vehicle acceleration.

The objective of this study is investigation possibilities to obtain main parameters of road vehicle ride comfort using formal matrix approach. The automobile is modeled as a dynamic system consist masses interconnected by springs and dampers with linear characteristics. The procedure is applied about four to eight wheel models. The engine, transmission, passengers and loads are presented like a simple masses suspended on a single springs. In the paper are written the main principles of calculation procedure for formal modeling typical vehicle dynamic system.
