Multimode electrically variable transmission having a ferrite magnet motor and method of operating the same |
摘要 |
A hybrid vehicle includes an internal combustion engine, a ferrite magnet motor and a rare earth magnet motor. When the vehicle is cruising at a steady speed, an electrically variable transmission mode of a transmission configures the rare earth magnet motor to provide a reaction force to the ferrite magnet motor so that the ferrite magnet motor operates at a high speed/low torque condition to minimize torque dependent losses in the ferrite magnet motor. When the vehicle is accelerating at higher speeds, a first torque transmitting mechanism provides a reaction torque to the ferrite magnet motor to eliminate the torque dependent losses in the ferrite magnet motor. |
