Opis:
Communication infrastructure of vehicles sub-assemblies has undergone three phases of development. The first phase was initiated by the need to reduce emission levels. The function of vehicle sub-assemblies health monitoring was introduced simultaneously. This phase took place in the 70s and 80s of the 20th century. The second phase was focused on the elimination of redundant sensors and implementation of new functions of the vehicle. This phase has been particularly noticeable since the beginning of the 21st century. At the moment, there are 2 directions of development. On the one hand, the works are being continued in the scope of autonomous movement of vehicle and, on the otherhand multimedia solutions are being introduced in order to make the time spent in a vehicle more attractive (multimedia, the Internet, …). The present study is focused on the mechanisms of protection applied in communication protocols used in vehicles. Furthermore, it contains the classification of communication methods, characteristics of the basic methods of protection incorporated in the described protocols and the practical cases of security breach. Therefore, it is possible to answer the question why it is possible for third persons to interfere into the communication network of a vehicle and to indicate potential methods of protection against the functioning disturbance in such communication networks.

On-board Diagnostics
Diagnostic Trouble Codes DTC
Opis:
Volkswagen model launched in 1968 is deemed as the first motor vehicle provided with on-board diagnostics functions. However, the introduction of systems for the monitoring of vehicle sub-assemblies contributing to emission levels in all vehicles was enforced by environmental protection requirements. The California Air Resources Board (CARB) introduced the necessity to use the basic functions of on-board diagnostics (OBD) in all the motor vehicles sold in California since 1991. The article presents the results of practical tests in the scope of on-board diagnostics for “premium” class vehicle. The tests were carried out by means of 4 diagnostic interfaces. Data volume obtained from motor vehicles varied depending on the applied device, although OBD II standards should be introduced in an identical manner by the manufacturers of motor vehicles and diagnostic devices.

Opis:
Energy harvesting consists in the processing and storage of energy which is normally dissipated to the ambient environment. This study presents two solutions using two methods of energy generation: conversion of solar energy into electricity on the road surface and energy recovery from road surface vibrations and displacements. The description of configuration of testing stand dedicated for road surface vibrations energy harvesting has been also included. Described testing stand will make it possible to verify the possibility of application of piezoelectric transducers in road pavement in terms of occurrence of damages and the value of generated energy.

Opis:
The Liquified Petroleum Gas (LPG) is currently the only widespread and available alternative fuel used in Poland for motor vehicles equipped with spark-ignition engines. Until the end of the 1980s, the monopoly on the fuel market had belonged to petrol and diesel oils. In the 1990s this monopoly was broken by LPG. The important impulse causing increase of concern with using alternative driving fuels by drivers has always been economy issues. The Liquified Petroleum Gas has been presented as an eco-friendly fuel, and with an attractive price it has also gained the title of an economical one. Over the last three decades, The Liquified Petroleum Gas has become an important player in the fuel market. The article presents current trends observed in the fuel market (LPG fuel and gasoline U95) used to power motor vehicles equipped with spark ignition engines, and analysis of the price volatility of these fuels in the period 2005÷2016.

Opis:
This article presents the use of GIS system for the construction of a hydraulic model in the network enterprise. The model has been built on the basis of data associated with the objects existing in the network and with their spatial relations. The data describing the network objects are usually transferred from existing technical documentation. The local stocktaking of networks is carried out in case of any doubts regarding data update status. The preparation of properly processed data, as well as verification of their correctness while entering them into a database is the most difficult and labour consuming phase of network modelling. A properly configured network model should incorporate at least the following features: the possibility to perform comprehensive analyses of the existing system functioning as well as analyses of the system modernization and extension variants in order to optimize technical solutions.
