NOVELTY - The hybrid drive device has combustion engine (20) and electric motor (5) that are arranged for driving drive axle (10). Electric generator (4) and closed chamber are in heat receiving contact with and surrounding the combustion engine. Piston unit (3) is arranged for driving generator. Chamber (1) has inlet (11) for receiving fluid and outlet (12) connected to piston unit for driving piston of piston unit, such that in operation fluid inside of chamber is pressurized by heat transferred from combustion engine to chamber (1). Pressurized fluid operates piston unit.    USE - Hybrid drive device e.g. hybrid motor for hybrid vehicle (claimed) and motor vehicle such as motor car, truck, motor bike used for shopping by people.    ADVANTAGE - The heat emitted by the combustion engine is used to generate electricity which is used to power the electric motor to drive the drive axle, such that heat generated by the combustion engine is effectively used, so as to increase the overall efficiency of the hybrid drive device. The chamber is constructed to surround or enclose the combustion engine, so that all the heat generated by the combustion engine is effectively utilized. The chamber is constructed in close contact with the combustion engine and exhaust of the combustion engine, for transferring the heat from the combustion engine to the chamber. The chamber has ventilator device that is arranged for circulating air inside the chamber form the outlet to the inlet to improve the heating of the fluid in the chamber. The controlling of hybrid engine saves the battery. The pollution caused by fossil fuels is prevented. The electric motor of the hybrid engine can move the vehicle without using the fuel engine at a certain speed, without too much speed loss. The hybrid vehicle comprises a chassis with a drive device compartment closable by the vehicle hood which can form portion of the chamber, to provide easy access to the combustion engine for maintenance when the hood is opened. The improved hybrid drive device or hybrid motor can be used for driving machines in a factory, for driving a propeller of a ship, for driving a locomotive or to generate electricity for general use. The electric motor is used for driving the vehicle at the portion of a journey from the current geographic position to a set destination. The operation of the electric motor for driving the vehicle can be controlled based on the available charge or electric power of the battery unit and a current geographic position of the vehicle that is distance of the vehicle to a set destination indicated by the geographic position determining system. The computer operated hybrid motor management system is arranged for controlling charging or recharging of the battery unit by the electric generator and an electric power source external of the vehicle. The hybrid motor management system is arranged for operating the inlet and outlet of the chamber for receiving fluid and driving the piston unit, and for controlling operation of the electric motor, electric generator, battery unit, and combustion engine. The hybrid vehicle is operated by the hybrid motor management system based on the geographic position determining system.
