The driver's reaction time is one of the most important parameters for the road pre-accident analysis. There are known the results of tests, in which the value of this parameter was determined in expected and unexpected road situations. But in some cases, this time may be longer e.g. in situations in which the driver's attention may be distracted by keeping observations other than the area, in front of the car's surroundings. There are many manoeuvres, when the driver is obliged to observe many areas at the same time. Thus, his attention must be turned away from the main area – in front of the vehicle. The paper presents the results of tests involving the measurement of the driver's attention time focused on observing the surrounding other than the car's path. During the test, the driver's attention was focus on observing the side and back mirror, car radio and at the mobile phone. Certain values can be potentially considered as extending the typical driver's reaction time. The results of the presented tests have practical applications and can be used in the process of issuing opinions on traffic accidents.

“…3 In order to solve the above issues, the researches were proposed to improve trapezoidal mechanism. Kulkarniet et al 4 carried out genetic algorithm optimization of Ackermann trapezoidal steering mechanism in the hydraulic steering system of an ultralong semi-trailer, the Ackermann steering error is reduced by optimizing the length of the tie rod. Shi et al 5 designed a new six-bar mechanism fitting Ackermann steering, combining genetic algorithm, and nonlinear function programming optimization algorithm to obtain the optimal mechanism parameters.…”

Ackermann steering is important for the steering performance of heavy multi-axle vehicle. When Ackermann steering condition is not satisfied, it will lead to abnormal tire wear. Traditional trapezoidal mechanism of heavy multi-axle vehicle is a single degree of freedom (DOF) mechanism, which is difficult to completely realize Ackermann steering. In this paper, a new two DOF electro-hydraulic servo steering system (TDEHSSS) by using a variable length tie rod is proposed for solving the issue. First, a complex nonlinear dynamic model of TDEHSSS is established. This model includes the two DOF mechanical model based on a Lagrange equation, the valve-controlled double steering power cylinders model and the valve-controlled tie rod cylinder model. Then, a simulation model is built through MATLAB/Simulink and the simulation results show that TDEHSSS can realize the proposed requirement. At last, a test bench is founded to verify model. It is indicated that the simulation and experimental curves are consistent, showing that mathematical model is in accordance with the experimental system. This research is valuable for analyzing TDEHSSS, designing advanced controllers, and finally realizing Ackermann steering for heavy multi-axle vehicles.

“…From this study resulted that the articulated vehicle stability depends on the trailer parameters (e.g., mass, centre of gravity and dimensions) and on the connection to the tractor. Articulated vehicles demonstrated their economic profitability, but as the number of these vehicles grows, it is observed that there is a need to improve their performance in terms of handling and control [11]. Nowadays the towing vehicle itself is not normally a source of instability, because it is controlled by the vehicle stability controller based on the actuation of the friction brakes [20].…”

The new maintenance system of semi-trailer combination as a most used road freight transport means is the subject of interest in this article. The real experiences from practice and creation of the FMEA analysis of the system using software support are the basis of wear and damage analysis of air brake system components used on the semi-trailer combination. The desire to improve market position of the company, customer satisfaction, but also the product specifications, government regulatory requirements, agency recommendations, and legal implications are the grounds for continuous improvement of the product quality, reliability and safety. These reasons push the product manufacturers to perform risk analyses, which helps them identify and minimize system failures during the life cycle of product. One of the risk analysis techniques recommended by international standards to identify possible failure causes is the FMEA methodology. It helps to locate the failures and reduce their consequences, so that the intended function of the machine is fulfilled. In this paper was presented the wear and damage analysis of individual components of air brake system and creating of the FMECA analysis for semi-trailer combination. Base on them, new methods to detect failures of components of air systems, preventive measures and set up of a new planned preventive maintenance system for air brakes was designed. The cost of the proposed maintenance system is 2.2 times higher than the cost of the current maintenance system, but it minimizes the failures and their consequences (traffic accidents).
