Sažetak (engleski)

This paper investigates potential of energy efficiency improvement for electric ve-hicle (EV) equipped with unequal front/rear-axle e-motors and disconnect clutch-es under straight-line driving conditions. First, a static optimization of front/rear torque distribution is performed for various driving cycles, which provides in-sights into energy efficiency gains and optimal powertrain operation including op-timal torque switching curve for two- and four-wheel drive modes. Disconnect clutches enable inactive motors to be switched off when operating in the 2WD mode to avoid their drag losses. A dynamic programming (DP)-based optimiza-tion of torque vectoring control trajectories is carried out to find the globally opti-mal energy saving potential. For clutch durability reasons, the number of clutch state changes is minimized along with energy consumption. Finally, a rule-based (RB) control strategy is proposed and verified against the DP Pareto optimal fron-tier benchmark for different certification driving cycles.
