This article presents a straightforward and effective way of adding the Internet Vehicles function to vehicles with different drive systems. By equipping vehicle transmission device that communicates vehicle’s on-board diagnostics system, current parameters operation can be read. allows for wireless application installed on mobile device. The related together location data from Global Positioning System are transferred cloud server. In this way, each system acquires function. Using setup, short trips in urban conditions were carried out an internal combustion engine plug-in hybrid vehicle. then processed using KNIME analytical platform. Signatures characterizing two types systems created. obtained results analyzed various tools experimentally validated. presented method is universally applicable quick recognition based signatures implementing k-means analysis. Acquiring processing used obtain important information about itself, road infrastructure, immediate surroundings, which translate into increased safety.

The article presents an algorithm for selecting electric vehicle your photovoltaic system. Generating electricity by distributed systems is a very visible trend across Europe. Individual and institutional owners are looking opportunities to save large amounts of money spent on the purchase electricity. Many times they have built system larger than their current energy needs. author suggests solution increase produced own needs instead giving it power grid at unfavorable prices. Such that will be charged with surplus energy. Research selection should start precise profile consumption from grid, production transferring its excess grid. next step characterize potential vehicle. characteristics include determination capacity traction battery methods charging. final stage analytical confirmation choice made. For this purpose, Metalog family distributions was used determine probability generating appropriate hourly amount needed charge

The following paper presents an innovative approach to determining vehicle precrash velocity when hitting immovable obstacle facing forward. Precrash is necessary in order perform a crash reconstruction. It needed for the time-space analysis of events, as well assesscrash mitigation and evaluate drivers’ technique tactics. For this task, authors are using Gaussian Process Regression (GPR). Such offers number advantages over currently used methods that prove be outdated considering modern vehicles. mathematical model was trained on database shared by National Highway Traffic Safety Administration.. This covers large tests different kind, however focus frontal collisions subcompact car class. Due low accuracy linear up till now, Authors developed determine EES parameter utilizing process regression. newly method effective accurate way vehicle’s shows promising results, demonstrated paper.

Our calculations show that despite higher costs ownership, case 7 years use (among Hungarian conditions), total cost Battery Electric Vehicles (BEV) is lower than Internal Combustion Engine (ICEV) each four segments analysed. purchasing power population regions EU clearly compared western regions, yet people this spend beyond financial means on motorization. Despite its unfavourable position, Hungary a particularly advantageous position other countries per capita terms spread BEVs. In long run, even taking prices into account, cars, general, has significant advantages from an point view; maintenance fuel (especially increased use) make EVs more cost-effective overall.
