Abstract:
1. A hybrid system for a vehicle comprising an engine, a transmission device for changing the speed of rotation of an input shaft and transmitting the rotation to vehicle wheels via an output shaft, a clutch for engaging or disengaging the output shaft of the engine with or from the input shaft of the transmission device, a rotational electric device serving as an electric motor and an electric generator, a power transmission mechanism for coupling the input and output shafts of the rotational electric device with the input shaft of the transmission device, and an accumulator element for accumulating electrical power supplied by the rotational electric device, comprising: means for calculating the required driving force of a vehicle; means for determining the output load allotted to the rotational electric device and the output load allotted to the engine in accordance with the accumulated charge in the accumulator element, in such a manner that the aforementioned required driving force is satisfied, wherein said determining means sets the ratios of output loads allotted to the rotational electric device and the engine are set in such a manner that, if the accumulated charge exceeds a prescribed value, the ratio of output load allotted to the rotational electric device is control means for controlling the outputs of the rotational electric device and the engine in such a manner that the respective allotted output loads are achieved, and engaging said clutch.
