Title:
HYBRID VEHICLE AND METHOD OF CONTROLLING THEREOF
Document Type and Number:
WIPO Patent Application WO/2011/155015
Kind Code:
A1
Abstract:
Provided is a hybrid vehicle, wherein a crankshaft (26) of an engine (22), an output shaft of a first motor generator (MG1), and an output shaft of a second motor generator (MG2) are mechanically interconnected with each other, directly or indirectly. Upon starting an engine, vibration restraining torque to be set periodically on the basis of the crankshaft angle is made to act upon the crankshaft (26), so that torque pulsation of the engine (22) is restrained. The output torque of the first motor generator (MG1) is controlled according to the sum of the motoring torque and a portion of the vibration restraining torque. The output torque of the second motor generator (MG1) is controlled according to the sum of a torque for assisting the insufficient torque worth of the portion of the vibration restraining torque outputted by the first motor generator, and the essential output torque for driving the vehicle.
