There is provided a hybrid vehicle driving system in which both an external combustion engine and an electric motor are used as power sources for driving wheels, and an advantage of the electric motor can compensate for a disadvantage of the external combustion engine, a hybrid vehicle, and a driving method. When a driver turns on an accelerator (43), a CPU (20) permits revolution of planetary gears (33, 33, ...), and a motor (11) rotates a ring gear (31) to drive wheels (41 and 41). Then, when the driver turns off the accelerator (43), the CPU (20) calculates a target RPM to be output by a Stirling engine (12) according to a depression amount and a depression time of the accelerator (43). When the RPM output by the Stirling engine (12) reaches close to the target RPM, the revolution of the planetary gears (33, 33, ...) is inhibited, the operation of the motor (11) is stopped, and the Stirling engine (12) rotates the ring gear (31) via a sun gear (32) and the planetary gears (33, 33, ...) to drive the wheels (41 and 41). |
