Opis:
In this article we present a simplified model of centre differential control. At the beginning, the introduction highlights important role of center differential control and tests carried out using mathematical models. This work contains the full development of a model, consisting of: the equations which describe the vehicle, the structure of the model, important values and parameters used in the simulation. All these components allow you to expand an existing model, thus is not necessary to create it from the beginning. It presents detailed equations which were realized by a simulation model with a simplified block diagram illustrating the structure of the model and on the next the full structure. Then a concept of a simplified torque of split control system was described and which will be continue as the basis for the simulation model. The action of the control system is presented by the simulation model implemented in Matlab Simulink. Model refers to a linear motion in different road conditions and using the control of centre differential. In the following defines the parameters and data used in the model and the fifth chapter contains sample waveforms of model variables along with their brief description. The last two points are synthetic applications and supporting literature.

Opis:
The study examines the effect of transformation ratio in power transmission system on engine efficiency as a function of passenger vehicle velocity (m = 1400 kg) with energy-saving vehicle drive. The study also presents working range in driving phases for energy-saving speed control up to 120 km/h for a simplified overall engine performance map for SI engine. Understanding of the presented considerations can be facilitated through relating with advantages of application of non-driving phases in low engine load phases (field 4 in overall engine performance map). Working points of SI engines in engine performance maps were divided in terms of energy-saving vehicle speed control into 4 ranges. Zone l is the most economic whereas zones 3 and 4 are the least energy-saving, which was also discussed by the author in other works. The study presents the location of engine working points in overall engine performance map during energy-saving vehicle speed control within the range of 30-120 km/h using two different 6-gear gearboxes. Working range for CI engine in simplified overall characteristics in truck, the impact of speed control upon fuel consumption in real traffic conditions, sum and difference characteristics of components of drive engine unitary power, area of maximal rise in overall engine efficiency after reduction of rotational speed, simplified SI engine performance maps, covering with economic zone of working point in energy-saving drive of vehicles are presented in the paper.
