Hybrid vehicle
First Claim
1. A hybrid vehicle propelled by drive wheels and comprising:
- (a) an internal combustion engine for generating torque in a driving state and for operating in a non-driving state;
(b) a drive shaft for, in the driving state, transmitting the generated torque from the engine to the drive wheels;
(c) an electromechanical unit, which is connected to said internal combustion engine for rotating said internal combustion engine, while operating in the non-driving state, to provide engine braking;
(d) an electric motor which, in a first mode, is driven by current supplied thereto and, in a second mode, receives torque from said drive wheels to produce a regenerative current;
(e) decelerating operation detecting means for detecting that a decelerating operation has been performed;
(f) a differential gear unit having at least a first gear element connected to said electromechanical unit, a second gear element connected to said drive shaft and a third gear element connected to said internal combustion engine, whereby said electromechanical unit is connected to said internal combustion engine through said differential gear unit;
(c) an engine controller for bringing said internal combustion engine into the non-driving state responsive to detection by said decelerating operation detecting means that a decelerating operation has been performed; and
(h) electromechanical unit control means for controlling said electromechanical unit when said internal combustion engine is in the non-driving state.

Abstract
A hybrid vehicle is provided which can produce a decelerating force without detriment to drive quality. The hybrid vehicle includes an internal combustion engine, an electromechanical unit, an electric motor, a decelerating operation detecting unit for detecting that a decelerating operation has been performed, a differential gear unit having at least a first gear element connected to the electromechanical unit, a second gear element connected to an output shaft and a third gear element connected to the internal combustion engine, an engine controller for bringing the internal combustion engine into a non-driving state when it is detected by the decelerating operation detecting unit that a decelerating operation has been performed. When it is detected by the decelerating operation detecting unit that a decelerating operation has been performed, the internal combustion engine is brought into the non-driving state, and the electromechanical unit control unit controls the electromechanical unit so as to compulsorily rotate the internal combustion engine.
