An electric power steering system for a vehicle includes a motor for providing assistance in turning the wheels of the vehicle. The motor is electrically connected to a controller. The controller includes a power device, such as a power transistor, electrically connected to the motor to variably provide electric power to the motor as needed. The controller also includes a gate drive device electrically connected to the power device for regulating operation the power device. A shutdown mechanism is electrically connected between the gate drive device and a power input. In the event of a fault, the shutdown mechanism isolates electrical power from the gate drive device. This prevents the power device from providing electric power to the power steering motor.
An electric power steering system for a vehicle comprising:
A controller for an electric power steering system having an electric power steering motor, said controller comprising:
An method of operating an electric power steering system for a vehicle, the system having an electric power steering motor, at least one power device electrically connected to the motor for providing electric power to the motor, and a gate drive device electrically connected to the at least one power device for regulating operation of the at least one power device, said method comprising the step of:
