Title:
ELECTRIC-POWERED VEHICLE AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2012/029170
Kind Code:
A1
Abstract:
A hybrid vehicle (20) is provided with a plurality of motor generators (MG1, MG2) for generating vehicle driving force and an engine (22). A motor ECU (45) controls the motor generators (MG1, MG2) in accordance with the respective torque command values thereof. The motor ECU (45) selects a motor generator for executing vibration damping control on the basis of the operating states of the motor generators (MG1, MG2). The output torque of the motor generator which executes the vibration damping control is controlled such that compensating torque corresponding to a periodic vibration damping torque component for cancelling a periodic fluctuation component of the rotation speed of drive wheels (39a, 39b) is superimposed on torque for generating the vehicle driving force.
