    Opis:
    The article presents the results of investigations concerning the relations between the technical state of cars and the exhaust gasses emission for different groups of vehicles. First, the measurements of the test group of4000 different vehicles have been made. Those measurements have been elaborated in order to define typical damages of vehicles. The percentage of faulty vehicles and the type of faults was estimated. The damages of vehicles have been carried out using typical diagnostic methods, electrical value measurements and exhaust gasses analysis. Those measurements also provided information about the number of vehicles with high level of gas emission. The results of investigations were compared to the requirements of each model of a given year. Next, the measurements of the test group of 1000 vehicles have been made in accordance with ECE Regulations and the methodology of periodical car inspection. Those measurements also gave information about the level of emission from each vehicle. The results of investigations were compared to the requirements of each model of a given year and the percentage of high polluting vehicles has been presented. The vehicles have been divided into different exhaust emission legislation classes. Next, the relation between the number of faulty vehicles and the level of exhaust emission for the first and the second group of vehicles has been elaborated and presented. The results of investigations and analysis show the number of faulty vehicles and its influence on the level of emission.

    Opis:
    This paper considers the results of studies on examination methods in scope of environmental protection such as exhaust emission, fuel consumption and noise emission. The reduction of exhaust gas emission of modern compression and spark ignition engines requires an optimization ofexisting diagnosing methods as well as the investigation of new approaches. The results of car inspections regarding environmental protection for more than four thousand vehicles have been compared to the requirements of ECE regulations and those of particular car producers. Eight hundred cars with a fault of gas emission and fuel consumption were examined in order to define typical damages. The possibilities of diagnosing the damages of mechanical and electrical systems of the engine have been carried out using electrical value measurements and exhaust gases analysis. The test results show that there is a necessity of elaborating new diagnosing methods enabling to find damages regarding exhaust emission and fuel consumption at their initial stage. One of the possible methods which could be applied is the evaluation of the quality of combustion process considering the values of parameters of engine performance coming from the detectors mounted to the engine. The so far carried out examinations have revealed that some mechanical damages of engines such as operating wear or unexpected faults do not make the diagnosing system react to the information.

    Opis:
    This article presents the results of investigations regarding the use of on-board diagnostic systems to assess the technical state of automotive vehicles, and the possibilities of early fault detecting. The examinations were carried out in order to establishifit is possible to evaluate the level of compatibility between diagnostic test units and on-board diagnostic systems in over three hundred models of vehicles which were produced by different manufactures. The investigations concerning the influence of examination conditions, the type of faults and the vehicle age upon the results and reliability of diagnostic tests were carried out. The suitability of fault codes which were recorded in the memory of diagnostic system while the vehicle was operating have been determined as far as the recognition of the type of faults is concerned. Additionally, the examinations of engine on a test stand were carried out as well. Sensitivity of diagnostic systems was tested regarding the changes of work parameters of the engine. The faults of engine were deliberately provoked and were examined at the early stage by on-board diagnostic systems. The test results show that there is a necessity of elaborating new diagnosing methods enabling to find damages regarding safety in road traffic.

    Opis:
    The article presents the concept of a maintenance-free inspection station intended for conducting drive-thru tests of commercial vehicles. The main purpose of building this type of diagnostic line is to carry out non-invasive, preliminary tests of heavy-duty vehicles entering the vehicle service area in terms of parameters affecting the safety of their operation in relation to the applicable standards. The main parameter to be assessed will be the concentration of toxic exhaust components, measured using remote sensing methods. In addition, the proposed diagnostic line can be supplemented with additional remote measurement systems, such as, for example, systems for assessing the condition of vehicle lighting, loads on individual axles and individual wheels of the vehicle, tire pressure, thermal load of the brake system, as well as a system for detecting leaks of fluids from the vehicle. Based on the carried out work, it has been shown that using the current specialist knowledge and the components of measurement systems available on the market, it is possible to develop an innovative diagnostic line using remote measurement methods.

    Opis:
    Every year too many people lose their lives and health on Polish roads. At best, it only ends with damage to their cars. The number of accidents is very high. Despite the construction of new, safer roads, the number of collisions continues to rise, and death, every year, is suffered by about three thousand accident participants. On average, forty-one thousand people are injured annually. The main causes of accidents are failure to adjust speed to prevailing conditions or traffic regulations, driving under the influence of alcohol and random events, as well as the technical condition of the vehicles. The purpose of the article is to answer the question of how the technical condition of the vehicles affects traffic safety. For this reason, an assessment of the technical condition of vehicles during a periodic examination at a vehicle inspection station was made. Based on the study, it can be concluded that the largest percentage of defects detected during the examination is in the tire 40% and steering 40%, defects that are particularly important from the point of view of traffic safety, which were demonstrated during the examination.

    Opis:
    Road freight transport is one of the main modes of transporting goods in the European Union. This reality puts pressure on carriers to make every transport of goods fast, safe, cheap, and efficient. Based on these requirements, lorry drivers are often forced by their employers to break the current social legislation in the European Union and the rules of the road. Compared to the current social legislation in force in different parts of the world, the European Union rules on driving times, breaks and rest periods for drivers engaged in road haulage and passenger transport are the strictest. An important factor and reason of serious and fatal traffic accidents, extensive damage to goods or property in road freight transport is a driver. This article presents three different types of experiments that were carried out, and the results may help to improve the current situation. The main aim of this study was to verify whether the actual regulations are safe and suitable and compare the results of daily work of professional drivers in two different measurements. Last measurement was conducted with using Eye-tacking technology, which aimed to verify impact of experiences on the reaction times of drivers. The authors believe that the results of individual measurements can contribute to increasing safety in road freight transport with preparing future extended studies and proposing the possible changes of current regulation.

    Opis:
    It is impossible to implement very tasks by diver, because of complexity of underwater environment and high pressure in the deep sea. These tasks can just be done by a vehicle that includes all special requirements such as: high maneuverability, precise controllability, and especially hovering capability. Underwater robots are integral parts of the industry and marine science. The application of the underwater vehicles has increased with the development of the activities in deep sea. This paper presents a special Hovering type Autonomous Underwater Vehicle (HAUV) for underwater missions. To provide the most suitable and efficient formation of vehicle thrusters for reduction of complexity of control strategies and control of the most degrees of freedom, in this paper, a new thrusters’ configuration is investigated, in terms of number of the thrusters, position and the thrust direction of the thrusters. The state feedback controller is designed according to the linear dynamic model and then applied to the non-linear model to validate the controller performance. Designed controller consists of three controllers: horizontal plane controller, vertical plane controller and surge controller. The last controller is developed to control the forward speed. For examination of the system behavior in presence of environmental disturbance and hydrodynamic coefficients uncertainty, the robustness of controller is also investigated.

    Opis:
    A few systems, such as steering, brakes or suspension, critically affect the vehicle's safety. In light of this, it is necessary to check these elements up to a certain age in order to maintain the vehicle in optimal safety conditions. This study is part of a project about effectiveness of Periodic Motor Vehicle Inspections (PMVI), in order to suggest metodologies, instruments and criterions to inspect the vehicle´s safety. It´s well known the relationship between steering geometries and the force in contact patch. The measurement of these geometries is important to evaluate the vehicle dynamic performance. The main objective is to evaluate the steering inspection method at low speed, current rejection criteria in order to analyze the effect of these results in vehicle´s safety behaviour in real dynamic conditions. The angle that has more influence on the PMVI inspection is the toe angle, being this one the principal parameter of analysis. Experimental force in contact patch with dynamometer plate and simulation results with CarSimTM have been carried out in order to validate the methodology of steering inspection and to check the information obtained in these tests.

    Opis:
    The solid particle number method was introduced in the European Union (EU) light-duty legislation for diesel vehicles to ensure the installation of the best-available technology for particles (i.e., wall-flow diesel particulate filters) without the uncertainties of the volatile nucleation mode and without the need of large investment for purchasing the equipment. Later it was extended to gasoline vehicles with direct injection engines, heavy-duty engines (both compression ignition and positive ignitions) and non-road mobile machinery engines. Real Driving Emissions (RDE) testing on the road with Portable Emissions Measurement Systems (PEMS) for particle number (and NOx) during type approval and in-service conformity testing was recently (in 2017) introduced for light-duty vehicles, and is under discussion for heavy-duty vehicles in-service conformity testing. This paper will summarize the existing legislation regarding solid particle number and discuss the on-going activities at EU level. The main focus at the moment is on improving the calibration procedures, and extending the lower detection size below 23 nm with interlaboratory exercises. In parallel, discussions are on-going to introduce testing at low ambient temperature, regeneration emissions in the light-duty regulation, a particle limit for other technologies such as gasoline port-fuel injection vehicles, and the feasibility of particle measurements to L-category vehicles (mopeds, motorcycles, tricycles and minicars). A short overview of periodical technical inspection investigations and the situation regarding non-exhaust traffic related sources with special focus on brakes and tyres will be described.
