Title: Power output device, its control method and hybrid vehicle
Inventor: NAGAMATSU SHIGETAKA
IPC: B60L50/16
Filed: 1998-04-16
Abstract: PROBLEM TO BE SOLVED: To improve the operation efficiency of a hybrid power output device with two output shafts. SOLUTION: A part of the output power of an engine 150 is transmitted to front wheels 116 via a clutch motor CM and the remaining power is regenerated as an electric power. A motor linked with rear wheels 118 is driven by using the electric power. In a hybrid vehicle which has the fundamental construction as described and enables four-wheel drive, a DC motor is provided between the engine 150 and the clutch motor CM as a generator G. In an overdriven state, an electric power is regenerated by the generator G to suppress the power transmitted to the front wheels 116, so as to prevent the power exceeding the requested power from being outputted from the front wheels 116. With this constitution, since it is not necessary to regenerate a power from the rear wheels 118, the circulation of the power is eliminated and an operation efficiency is improved.  Furthermore, as the DC motor is employed, the improvement can be realized with a very simple construction.
