  • Patent number: 9026393
    Abstract: A High Voltage Interlock Strategy (HVIS) uses feedback current to detect cable connectivity status for a high-voltage cable configured to connect a power conversion circuit with a remote permanent magnet synchronous machine (PMSM). One or more feedback factors are calculated based on detected feedback current. Various algorithms for calculating a feedback factor, and for determining connectivity status based on calculated feedback factors, can be practiced, according to the PMSM operational mode. Fault detection action can be performed in response to detecting a cable disconnect. The HVIS can be implemented by software, making it a safe, economical solution for cable connectivity detection.

  • Patent number: 8527123
    Abstract: 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.
