Opis:: The paper describes systems responsible for driving safety of vehicles weighing up to 3.5 t. It is focused on selected failures (fouling) of braking systems that are typical during motor cars operation. Simulation testing regarding effect of selected failures (fouling) of braking system elements on braking force and braking efficiency were performed. In order to perform such testing, author of the paper worked out the methodology of testing which is also described here. The test results (partial) are displayed as tables and charts. The negative effect of selected failures on braking force and braking efficiency index is influencing directly on motor cars driving safety. It is also emphasized that it is important to maintain and observe automotive manufacturers’ technical requirements regarding braking system elements such as tyre pressure, tyre tread condition, brake shoes wear, etc. Basing on the test results it is found that excessive wear of tyres and brake shoes wear could be the reason of significant WSH index decrease resulting in faulty car. This can be visible through lower than allowable level of braking efficiency index WSH, which is the basic legal diagnostic parameter of break system condition assessment. Replacing such elements significantly improves braking efficiency index WSH.

Opis:: In this paper, selected elements of the theory of the car's motion were presented. It was emphasised that it is extremely important to know the rules of behaviour of a car in curvilinear motion, an example of which is a curve, especially when driving in adverse weather conditions resulting in the significant reduction of the car's traction to the surface. The active electronic stability programme (ESP) of the car's trajectory, its principle of operation and benefits of use were briefly discussed. The next part was to present the basics of the mechanics of a vehicle's motion, especially the forces acting on a car during its stop phase, the forces acting on the curve of the road. On this basis, the basic equilibrium equations were presented, which in turn led to defining the correlation for determining the so-called safe speed of driving in circular motion, which also guarantees the impossibility of the cars skidding. In the further part, the calculations, in accordance with the BMW 320d car's data were made. Hypothetically, it was assumed that this car might have only a front-wheel drive, only a rear-wheel drive or a four-wheel drive. The idea was to check to what extent the type of drive has an impact on the achieved value of the safe speed of driving in the circular motion with a minimum turning radius for this vehicle. The article was completed with short conclusions, in which the importance of the electronic stability programme (ESP) of the car's trajectory was emphasised.

Opis:: Selected experimental research results of truck tire in steady-state side cornering and transient cornering conditions are presented in this paper. Experimental research results of the tire have been used in simulation research of medium duty truck in nonlinear driving conditions. The paper presents the structure of the vehicle dynamics model and a description of applied tire-road interaction model. Simulation research of the vehicle lateral dynamics has been performed in two variants: without and with the model of tire relaxation. During research, the tire relaxation length has been also changed. The steering wheel angle changes were forced as continuous sinusoidal excitation signal with a constant amplitude and with continuously increasing frequency. There have been analysed basic physical quantities characterizing the vehicle lateral dynamics connected with the vehicle active safety, especially including body yaw velocity and lateral acceleration in the centre of the truck body mass. An analysis of research results have been performed in the time and frequency domain. Time courses of analysed physical quantities and their frequency spectrum, obtained for tire-road interaction model without and with the tire relaxation (with different values of relaxation length) have been compared. Based on the simulation research results there have been considered the influence of tire relaxation on the vehicle performance. There have been shown that the tire relaxation can significantly change courses of observed physical quantities connected with vehicle lateral dynamics connected with vehicle driving safety.

Opis:: The article deals with the problems connected with road traffic safety highlighting driver’s ability to notice an untypical obstacle in the light of low beam headlights while driving in the night. Visibility of an unlit object during the night is not only related to its motion but also to the necessity of its being lit to up to the required minimum height. On the basis of a study of a road accident, it was found that the standards accepted in reconstruction of the accident for determination of the light beam height to be used for lighting an obstacle should not be taken for granted. The driver’s surprise at the sight of an unlit obstacle is accompanied with the need to direct the light beam higher, which causes shortening of the distance available for a driver to react in an attempt to avoid hitting into an obstacle. An analysis of this case shows that verification of road accidents involving a crash with an untypical, incompatible obstacle that happen during the night needs to be carried out with attention and care. A simulation program V-SIM4 version and Ratschbacher AutoView database was used for calculation of the possibility to avoid an accident. The results obtained on the basis of the authors own investigations can also be used in information campaigns, education for road safety improvement and development of proper attitudes of the road traffic users.

Opis:: The aim of the paper is to present the European Project "MODULE CLOSE TO". The project is executed in eleven European Union countries. The paper describes main objectives and guidelines of the project. The project's main result in the final stage should be the development of conditions for unification of drivers''training system across Europe by introducing into drivers' training new educational module. The module consists in realization of educational method called "peer-to-peer" during drivers' training, which is taken from addiction treatment prevention in which a peer reports on a problem to another peer. In drivers' training, the course participants are confronted with road accident offenders (course participants' peers) and their stories, which should lead to positive changes in attitudes and behaviours of young, beginning drivers and therefore to permanent reduction in number of both road accidents and their victims. The preliminary research confirmed that classes with road accident offenders have a positive influence on developing proper attitudes of young drivers. A discussion concentrated on offender, his/her susceptibility to risky behaviours, accident's circumstances, confrontation with its consequences and on serving an adjudged sentence makes an impression on young course participants. The project anticipates introduction of pilot classes in driving schools, high schools, etc. within the framework of drivers' training with participation of road accident offenders and also evaluation of its influence on course participants. The final effect of the project will be the development of conditions for introducing a new educational module into existing drivers' training system as well as developing conditions for recruiting accident offenders and actions motivating them to join the project realization.

Opis:: There are a lot of activities world-wide, aimed at increasing road safety. According to the statistics, young novice drivers are at the highest risk of being involved in crashes, and more often than other age groups, cause danger on the road. A proper driving education of teenagers and young persons may contribute to a decrease of accident risk. One of the solutions is accompanied driving, which currently exists in 17 European countries, USA, Canada, Australia, New Zealand. It allows a driver to start driver training before he or she has reached the legal age for receiving a driving license. Currently, a draft of national law concerning drivers, which introduces accompanied driving, is being considered in Poland. This study concerns drafting of the new regulations, and it constitutes a proposal of methodological and organizational solutions of accompanied driving, trainings and preparation of people participating in it in Poland. The study describes the role of accompanying person as a lay instructor and as a model for road traffic behaviour.
