CONTROL METHOD OF THE FUNCTIONING MODE OF A HYBRID DRIVE ASSEMBLY FOR VEHICLES AND A HYBRID DRIVE ASSEMBLY USING SAID METHOD

摘要

A management method of a hybrid drive assembly for vehicles, in particular scooters, comprising at least one engine (3) and an electric machine (32). The method comprises the phases of operating the engine that it does not provide torque and operating the electric machine that it functions as generator for charging an accumulator (36) when the torque requested is negative. Operating the engine and/or the electric machine to satisfy the required torque, and/or bring the accumulator to a pre-established charge level and/or run the 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 engine. Furthermore, when requested by the pilot and in accordance with the charge level of the batteries (36), the control method switches off the engine and drives the electric machine only to supply the torque requested.
