The evolution of the vehicle industry, as well as the sudden increase in competition between manufacturing companies, dictates the increase in the obligations of manufacturers to meet the increasingly complex requirements of users, in terms of ergonomics, comfort, safety, as well as environmental protection. Researchers have investigated the factors influencing the ergonomics of the vehicle interior which is very practical to improve safety and driving performance in addition, it can significantly reduce the development costs and the development cycle of new vehicle concepts, but the concept of ergonomics was not clearly articulated from a human perspective. This study aims to interpret the definition of ergonomics in the context of the interior of the vehicles and also in the study the influencing factors of the ergonomics of the index layer of the human-machine interaction interface, in the central console of the vehicle, are identified. The influencing factors are analyzed by creating and visualizing bibliometric networks in VOSViewer. [ABSTRACT FROM AUTHOR]

Noise, vibration, and harshness (NVH) researchers spend inexhaustible resources of materials, time and money in determining the objective factors that are important in ensuring acoustic comfort in vehicles. In this paper, the factors that directly influence the interior acoustic pressure level in a heavy-duty vehicle were investigated. It was determined using specific descriptors and different units of measurement in assessment of sound levels and the impact generated by noise, the level of interior acoustic pressure and particular values of some prominent sources of noise in the operation of vehicles (engine, HVAC system), taking into account the factors of insurance and thermal comfort, with the aim of determining the cumulative impact at the board of heavy vehicles due to noise.
