摘要： A vehicle electric power steering (EPS) control system includes a motor (48) operatively coupled to an EPS linkage arrangement (14), the motor comprising a first winding (72) and a second winding (84). Also included is a power source (68) for the motor. Further included is a controller (62) in operative communication with the motor and the power source. The controller includes a microprocessor (76) configured to receive input from a torque sensor (80) and a motor sensor (82). The EPS controller also includes a first field-effect transistor (FET) driver (74) in operative communication with the microprocessor and a first plurality of FETs (70) operatively connected to the first winding of the motor. The EPS controller further includes a second FET driver (88) in operative communication with the microprocessor and a second plurality of FETs (86) operatively connected to the second winding of the motor.

摘要： Provided is an electric drive device which controls a current supplied to coils during normal operation so as to be less than a current limit value when normal, which is determined from heat generating properties and heat radiating properties of a thermally coupled body that includes the coils and an inverter circuit. When an abnormality in each group or each phase of the coils and the inverter circuit is detected, the supply of current to all phases of a group suffering an abnormality in the coils, or to a phase that is not capable of continuous operation, is stopped or reduced; and the limit value of the current supplied to a coil that is capable of continuous operation is reset to a current limit value in the event of abnormality, which is larger than the current limit value when normal, within the range of improvement of the heat generating properties of the thermally coupled body due to the stopping or reduction of the supply of current.
