Nowadays disabled persons are actively integrated into social life and different compensatory equipment allows them to work and travel independently. The wheelchair is one of such means; it provides mobility function for physically impaired persons. Not every disabled person has possibilities to travel by his own car, it is more convenient to use public transport facilities. Wheelchair users' transportation safety is one of the most important problems facing transit providers and engineers. Improperly or totally unsecured wheelchair can lose the stability and tip over during the emergency driving situations and result in passenger falling and becoming injured. The main object of the scientific research work is complex dynamic system "Man - Wheelchair - Vehicle", which is under action of environmental factors (road roughness, motion oscillations of vehicle). The main tasks of the work are to form and research non-linear model of dynamic system considered, to define system's stability limits and to provide means for save travel. Also to determine main characteristics of the external action and analyze its influence on to considered system; to build engineering computation methodology for estimation of the rational parameters to fasten the wheelchair to the vehicle.
