VEHICLE ELECTRIC POWER STEERING CONTROL SYSTEM

摘要

A vehicle electric power steering (EPS) control system includes a motor operatively coupled to an EPS linkage arrangement, the motor comprising a first winding and a second winding. Also included is a power source for the motor. Further included is a controller in operative communication with the motor and the power source. The controller includes a microprocessor configured to receive input from a torque sensor and a motor sensor. The EPS controller also includes a first field-effect transistor (FET) driver in operative communication with the microprocessor and a first plurality of FETs operatively connected to the first winding of the motor. The EPS controller further includes a second FET driver in operative communication with the microprocessor and a second plurality of FETs operatively connected to the second winding of the motor.
