METHOD FOR DETERMINING THE FUEL CONSUMPTION OF A COMBUSTION ENGINE POWER TRAIN OF EQUIVALENT POWER TO THAT OF A HYBRID POWER TRAIN

摘要

Method for determining the fuel consumption of a combustion engine power train of equivalent power to that of a hybrid power train comprising a combustion engine and an electric machine. The method involves the following steps: calculating an equivalent combustion-engine torque equal to the sum of the combustion engine torque of the hybrid vehicle and of the product of the torque of the electric machine of the hybrid vehicle times the drive ratio, then determining the instantaneous fuel consumption of an equivalent vehicle fitted only with a combustion engine developing the determined equivalent combustion-engine torque.
