Seat sides are made from durable material – leather. The theoretical part describes the use of skin-vehicle Origins: Sled horse ammunition, the use of skin carriage, the first car and the interior of the first motorcycle seat. It also provides an overview of the Lithuanian and foreign companies engaged in the vehicle interior "tuning" and a brief mention of their specific activities, materials used, contacts and other information. These companies include not only cars, motorcycles and finish. They can update and airplanes, boats, campers, buses, coaches and most other vehicles. Business activity is detected updating almost any vehicle interior components: seats, panels, door panels, gear lever, steering wheel, floor and ceilings.

Emergency braking of a vehicle is bound with many factors, such as the behaviour of the driver, the drive of the vehicle braking system, the braking mechanisms, the condition of the tyres, and the properties of the pavement. This process involves all parameters of the system “the driver – the vehicle – the road”. In order to investigate the efficiency of braking process upon specific conditions, it is necessary to examine all physical processes that take place in the vehicle on pressing the brake pedal. Upon the completion of the experimental and theoretical investigation on emergency braking of vehicles a general mathematical model of vehicle with hydraulic braking system on its emergency braking had been developed. The dynamic, thermodynamic in solid systems and fluid hydrodynamic processes were assessed. The model enables to examine various cases of emergency braking with assessment of the driver’s reaction, parameters of the vehicle’ technical condition and the pavement condition. A general mathematical model of vehicle with hydraulic braking system that’s computing is realized in the system of the applied software Compaq Visual Fortran Professional system provides possibilities for research the hydrodynamic processes that take place in the system of braking; enables to define more closely the movement parameters of the vehicle in the emergency braking mode and may be applied for analysis of traffic events, improvement of vehicle braking systems as well as a manual for...

Šiame darbe aprašytas automobilio numerio identifikavimo uždavinys, šio uždavinio skaidymas į smulkesnes užduotis, tokias kaip numerio lokalizavimas nuotraukoje, numerio suskaidymas į atskirus simbolius, bei rastų simbolių identifikavimas. Kiekvienai šiai užduočiai realizuota po du algoritmus. Numerio lokalizavimo algoritmai remiasi kontūrų išskyrimu ir spalvų intensyvumu, bei morfologinėmis operacijomis nuotraukoje. Surasto numerio skaidymo į simbolius algoritmai remiasi statistiniu pasiskirstymu bei objektų išskyrimu. Simboliams atpažinti panaudota koreliacijos skaičiavimas tarp šablonų ir atpažįstamojo simbolio, bei dirbtinis neuroninis tinklas. Taip pat apžvelgta šiuo metu pasaulyje naudojamas technologijas ir algoritmai, sprendžiantys šį uždavinį bei palyginti rezultatai su savais. / This paper describes the task of vehicle number identification. It is further divided into smaller tasks, such as the localization of the number in the picture, the splitting of the number into individual symbols and the identification of the located symbols. Two algorithms were allocated for each task. The number localization algorithm is based on the exclusion of the contours, colour intensity and morphological operations in the picture. The algorithms used to divide the symbols of the identified number are based on the statistical distribution and object separation. Correlation calculation is used between the templates, identifiable symbol and artificial neural network. Moreover, the paper discusses the technologies and algorithms currently used across the world when dealing with such task, and compares it with the results of this paper.

The suspension of the motor vehicle is one of the most important elements of the flexible mounted and inflexible mounted masses of the vehicle bodywork, and most attention is paid to its exploration and improvement. Analysis of models of equivalent oscillation systems of motor vehicles testifies that the evaluation of motor vehicle oscillations and modelling of its motion modes is still very topical and requires further research. Suspension models of motor vehicles offered in publications regard only the influence of road irregularities, and the modernisation of these models is directed towards the improvement of passengers’ comfort. However not much research has been done on the influence of oscillations of flexible mounted and inflexible mounted masses of the bodyworks of vehicles in the process of braking; also there is not much investigation of the post-accident identification of the vehicle’s movement mode corresponding to the deformations of the suspension and the longitudinal pitch of the bodywork. Research of oscillations in the conditions of emergency braking is primarily important for the work in two practical directions: 1) improvement of calculation methods of motor vehicle’s response to external impact in the conditions of real operation; 2) further improvement of research methods on the road, and analysis of fait accompli road accidents related to oscillations in the emergency braking. Methodology defining the oscillations occurring in the braking may be applied... [to full text]
