Ushbu maqolada shahar sharoitida avtomobillarning harakat rejimlarini optimal tanlash orqali yonilg‘i sarfini
kamaytirish masalasi o‘rganilgan. Tadqiqotda bir o‘rkachli trapetsiyasimon tezlik profili asosida Nexia avtomobili uchun 30,
40, 50, 60 va 70 km/soat maksimal tezliklarda, turli tezlanish (0,5–3,0 m/s²) va sekinlanish (0,3–4,0 m/s²) qiymatlarida 240
dan ortiq harakat profillari hisoblab chiqilgan. MATLAB/Simulink dasturida teskari yondashuv (backward model) asosida
yonilg‘i sarfini aniqlovchi model ishlab chiqilgan. Natijalar asosida har bir maksimal tezlik uchun eng tejamkor (eko)
rejim aniqlangan. Eng past yonilg‘i sarfi 50 km/soat maksimal tezlikda, a = 2,5 m/s² tezlanish va j = 0,3 m/s² sekinlanish
qiymatlarida kuzatilib, 6,60 l/100 km ni tashkil etgan. Muhim ilmiy natija sifatida aniqlanishicha, ma’lum chegaragacha
tezroq tezlanish yonilg‘i sarfini kamaytirishga yordam berishi mumkin, silliq va nazoratli sekinlanish esa samaradorlikni
oshiradi. Olingan natijalar haydovchilarga optimal tezlanish va silliq sekinlashuv orqali yonilg‘i sarfini sezilarli darajada
kamaytirish mumkinligini ko‘rsatadi.
