The present invention relates to a management method of the functioning mode of a hybrid drive assembly for vehicles, in particular scooters, and a hybrid drive assembly, comprising at least one internal combustion engine and an electric machine, using the method. The method according to the invention comprises the phases of determining a desired torque and a vehicle state on the basis of a set of received input parameters and/or commands and is characterized in that it comprises the phases of operating the internal combustion engine so that it does not provide torque and operating the electric machine so, that it functions as generator for charging an accumulator, when the torque requested is negative; operating the internal combustion engine and/or the electric machine so as to satisfy the required torque, and/or bring the accumulator to a pre-established charge level and/or run the internal combustion engine under maximum efficiency regime conditions, when the torque required is positive and lower than the maximum torque which can be supplied by the internal combustion engine; and operating the internal combustion engine and/ or the electric machine with the supply of a propulsive torque so as to satisfy the torque required, when the desired torque is positive and higher than the maximum torque which can be supplied by the internal combustion engine. Furthermore, when requested by the pilot and in accordance with the charge level of the batteries, the control method switches off the internal combustion engine and drives the electric engine only so as to supply the torque requested. |
