Abstract:

The presented diploma thesis deals with the measurement of car deceleration during engine braking from different starting speeds and different speed gears with a sample of vehicles. This piece of work consists of a theoretical part, where problem background is defined, selected driving parameters including the manner how to measure them are explained and the facts in the field of structural characteristics of the vehicle are given, further from a design of measurement methodology that gives an overall plan of implementation, all the respective information and a description of handling with decelerometer, further from a real measurement of the deceleration including an interpretation of partial obtained values and finally from the evaluation of all results with appropriate conclusions.

Keywords:

Motion resistances, gear ratios, deceleration, engine braking, decelerometer.
