Patent number: 8527123Abstract: In a hybrid electric vehicle (HEV), the available energy from a battery may be inadequate to drive a motor to generate additional torque sufficient for driveability upon a request for an increase in wheel torque. The motor may then be operated in a lossy, inefficient mode. When the motor operates in the lossy mode, engine power can be increased such that the sum of the engine power and the maximum available battery power may exceed requested wheel power. The increased engine power may be dissipated as heat in the motor until an increase in wheel torque is requested, whereby the motor may switch from the lossy mode back to a normal, efficient mode. By switching back to the normal mode, the excessive engine power that was being dissipated as heat in the motor may contribute to the output torque of the motor.Type: GrantFiled: September 29, 2010Date of Patent: September 3, 2013Assignee: Ford Global Technologies, LLCInventors: Thomas Chrostowski, Joseph Youqing Xiang
