Abstract:
1. A controller for a hybrid vehicle, the hybrid vehicle including: an internal combustion engine and a motor, which are provided as power sources for driving traction wheels of the vehicle; power split means for splitting a crankshaft power of the internal combustion engine into two drivelines to drive the traction wheels of the vehicle using one of the drivelines; and a generator coupled to the other driveline of the power split means, torque of the motor being allowed to act upon the one of the drivelines of the power split means to drive the traction wheels of the vehicle during the operation of the motor, the controller comprising: motor drive mode determination means which determines whether the vehicle is in a motor drive mode in which only the motor is used to drive the vehicle with the internal combustion engine at rest; and control means which controls the torque produced in the generator in such a manner that if it is determined that the vehicle is in the motor drive mode, the torque to act upon the crankshaft from outside the internal combustion engine is generally zero.
