The Parameters of Agricultural Vehicle Active Safety

Abstract

In this paper the problems of the agricultural vehicle active safety are discussed. The parameters of active safety are defined with respect to vehicle stability and controllability. In this sense a vehicle train model has been developed to study system response. The yaw rates of the two vehicle units, tractor and trailer, then, the sideslip angle of tractor and articulation angle tractor – trailer at step steering input is determined. The results are presented and discussed as base to development of the vehicle safety assessment criterion.

U ovom radu su diskutovani problemi aktivne bezbednosti poljoprivrednih vozila. Parametri aktivne bezbednosti su definisani sa aspekta stabilnosti i upravljivosti vozila. U ovom smislu, razvijen je model sprega vozila za proučavanje odgovora sistema. Određene su ugaone brzine zaokretanja dva spregnuta vozila, traktora i prikolice, zatim, ugao skretanja traktora, i ugao između prikolice i traktora, pri naglom zaokretanju točka upravljača. Rezultati su prikazani i diskutovani kao baza za razvoj kriterijuma procene aktivne bezbednosti vozila.
