Innovations in electric vehicle technologies are offering promising low pollution solutions and advanced propulsion architectures that are especially interesting for the use in niche vehicles operating in a natural environment. In contrast to various hybrid solutions with central electric motors, the in-wheel propulsion system offers unique vehicle efficiency and driving performances. In this paper, a design process of in-wheel motors for a compact low pollution "all-terrain" vehicle with four in-wheel motors is presented. Each motor should reach a peak torque between 600 to 800 Nm. The demands for the vehicle are translated to the required motor characteristics which served as the input to the specially developed software for the Elaphe electromagnetic topology parameters selection. In addition, the motor was analysed from the thermal point of view. This specific Elaphe motor can obtain 600 Nm of continuous torque and over 1000 Nm peak torque with active mass of 15.6kg only.

COBISS.SI-ID: 12281627Due to increasing demand for reduced gas and noise emissions from vehicles in urban traffic, in the following years more focus will be placed on comprehensive and economically efficient solutions. Numerous vehicle manufacturers already offer good solutions such as use of CNG in propulsion systems, hybrid vehicles and even highly revolutionary solutions with 100 % electrification. Another important aspect are users who have specific demands, technical concerns as well as financial capabilities. Herein presented is the concept of a city hybrid bus which can be developed and manufactured in a local environment. The vehicle will have suitable functionality and it will enable optimization for a local user and infrastructure.

COBISS.SI-ID: 12276507Technical specification prescribes construction (shape, optical characteristics, adjustability) and material (resistance to loads and elements) properties of traffic mirrors. It also includes criteria for placement and procedures for their verification. An appendix to the specification contains forms for entering and archiving the results of individual test.
F.23 Development of new system-wide, normative and programme solutions, and methods
COBISS.SI-ID: 12631067The project includes production of technical documentation for the purpose of a tender for the manufacture of crash cushions, which help protect vehicles and vehicle occupants in the events of impacts with tunnel walls of SOS niches. The technical documentation is produced based on the results of the research project No. 2403001444/S entitled »Comparative traffic safety study of the tunnel niche wall protection by means of steel safety barrier (SSB) or crash cushion« and includes an assembly drawing of the crash cushion as well as a description of all compund elements of the crash cushion. The documentation relates to the attachment of the crash cushion to the tunnel niche wall as well as to an additional beam.
F.07 Improvements to an existing product
COBISS.SI-ID: 12419611The paper discusses the issue of vehicle impacts with trees. Real-life situations of accidents have shown that in the event of a vehicle impact with a tree the tree functions as a rigid obstruction. In such events, high vehicle decelerations occur as well as penetration of a tree and vehicle parts into the passenger compartment, which may cause critical injuries to vehicle occupants. Under conditions determined by the EN 1317 standard, FEM simulations were performed of vehicle impacts with trees of different sizes. Also determined were maximal tree sizes which according to the EN 1317 standard still enable passenger safety during vehicle impacts.
