PROBLEM TO BE SOLVED: To provide a hybrid-vehicular control method enabling improvement in an energy regeneration efficiency at deceleration without compromising the drivability.SOLUTION: In a hybrid vehicle 1 in which one end of a crank shaft 3 of an engine 2 is connected to a pair of drive wheels 6, 6 via a clutch 4, having a lockup mechanism, and an automatic transmission 5, with the other end of the crank shaft 3 connected mechanically to a motor-generator 9, an HCU 18 locks up the clutch 4 when an accelerator is turned off, calculates vehicular travel resistance force F from air resistance force Fa exerted to the hybrid vehicle 1, rolling resistance force Fr and engine-brake force Fe, multiplies with a pre-set determination factor kand then calculates regenerative torque Trequired to the motor-generator 9.SELECTED DRAWING: Figure 2 |
