HYBRID VEHICLE AND ITS CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To sufficiently suppress the generation of shock caused by release of fixing of rotation with a fixing means. SOLUTION: This hybrid vehicle is equipped with an engine 11; a dynamo motor 16; an output shaft 14 connected to a driving wheel; a differential gear device; a fixing means for mechanically fixing the rotation of the dynamo motor 16; a correction value calculation processing means 91 for calculating the correction value, based on estimation engine torque calculated by estimation and dynamo motor torque; and an engine torque correction processing means 92 for correcting the estimation torque with the correction value. Since the correction value is calculated, based on the estimation torque calculated by estimation and the dynamo motor torque and the estimation torque is corrected with the correction value, addition of the utilization environment of the engine to a rotor of the dynamo motor after the fixing of rotation with the fixing means is released can be prevented.
