Nonlinearity of acceleration influences sensitive passengers, who experience nausea while in a moving vehicle. This control system implements advanced engine torque management for control of the pulling force, which defines vehicle acceleration dynamics with regard to passenger comfort. A theoretical model for the linear acceleration of the vehicle was developed. The function was defined to control acceleration intensity, and it determines conditions for acceleration properties to be linear. Programming code was written to manage engine charge according to acceleration function. A controller has been developed to be the executive device of the programming code, and to manage engine charge. In the experiments, the variable acceleration is converted to constant with the choice of acceleration intensity value, as the driving parameterNamen članka je izboljšanje udobja potnikov, ki med vožnjo trpijo za slabostjo (morsko boleznijo). Glavni vzrok slabosti potnikov med vožnjo so nihanja sistema vzmetenja vozila ter spremenljiv pospešek vozila. Spremenljivi pospešek je bil zato pretvorjen v konstanten pospešek na najdaljšem delu razdalje, ki jo vozilo prevozi med pospeševanjem. V raziskavi sta bila postavljena fizikalno-matematični model dinamike pospeševanja vozila in programski model za upravljanje s pospeševanjem vozila. V prvi fazi raziskave so bile opravljene računalniške simulacije skladno s programskim modelom. V drugi fazi raziskave so bili opravljeni eksperimenti z vozili v realnih pogojihTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
