The introduction of autonomous cars will help to improve road traffic safety, and the use a cargo trailer improves energy efficiency transport. One critical (collision) situations has been considered, where immediate counteraction is required in space that only partly defined. This research work was aimed at determining impact trajectory planning method values some parameters control system on feasibility safe avoidance an obstacle suddenly appeared. assumed be motor vehicle moving...

Abstract The effects of a road accident where one vehicle hits its front on the side another are explored. In such cases, impacted vehicle’s is usually significantly deformed, which causes risk serious injury to occupants. An analysis front-to-side collision covers many nonlinear and highly complex processes, especially when it based energy balance. For analysis, model motorcar dummy representing driver was prepared. simulations carried out were supplemented with important experimental test...

The fundamentals of modelling the processes that take place between motor cars during their front-to-side collision have been analysed. This type predominates in vehicle accidents occurring road traffic Poland. kinematics contact phase and deformation develop collisions is based on findings from numerous tests, results which provide grounds for construction physical models formulation analytical descriptions these phenomena short duration. analysis changes angular positions relative...

Abstract The kinematics of the process deformation motorcar body side in culminating phase a front-to-side vehicle collision has been examined as possible basis for analyzing and modeling emergence hazard to car occupants during road accident. course such accidents complex nature their models are necessarily based on approximation non-linear elastoplastic characteristics impact processes, especially transition from compression restitution process. For be obtained, lot experimental tests have...

The safety of road users is one the priority issues taken into account in both operation and design vehicles. presented work part a study that aims to develop method for parametric assessment driver behavior. driving style depends on their skills psychophysical characteristics, type performance vehicle used by driver, road. This involves continuous measurement longitudinal lateral acceleration values body. paper analyzes how influences structure maneuvers undertaken driver. formulates...

Front-to-side collisions of motor vehicles very often occur on Polish roads. Every fourth road accident may be defined as a collision this kind between moving vehicles. The analysis effects, including the reconstruction process, is usually based results measurements post-accident vehicle deformation and information about body stiffness. Unfortunately, characteristic curves that would represent car side hardly available.

The results of the analysis operation heavy-duty vehicles with high load capacity (tractor units trailers) have been presented. road transport cargo relies heavily on this type. Performing role is associated energy consumption. Laden and unladen driving were investigated. collected data guaranteed constancy numerous parameters, including investigation same model under both loaded unloaded conditions identical roads. assessment focused changes in techniques consumption during significant...

Abstract A vehicles’ collision is a complex energy process, determined by many factors. In the front-to-side collision, hazards for he occupants of struck vehicle results from inertial loads they are subjected to together with and excessive deformation bodywork, often involving space occupied people. Action needed reduce this hazard. One such actions increase stiffness side part body in order limit range its deformation. However, an activity that requires compromise approach, because as...

Extensive environmental protection activities include the promotion of alternative drive systems for motor vehicles. An important role in this field is played by hybrid vehicles, with their low operation costs being a strong marketing argument. Can such economies be conducive to intensity use vehicles compared conventional systems? To answer question, was observed few different countries. The attention focused on occurrence extreme (very and very high) mileage values within comparable...

Abstract Independent transport of people with special needs often requires the adaptation a motorcar to increase comfort use and enable proper operating vehicle. This involves, for example, mounting devices on steering wheel. violates so-called survival zone, defined by (UN/ECE) regulation No. 21. can deteriorate occupant’s safety. study shows risk driver caused an additional knob mounted Model tests were prepared carried out PC-Crash program environment. The simulations frontal collisions...
