Abstract
A method and system for controlling an electrical steering system supports both manned and unmanned operation of a steering system for a vehicle. A steering wheel is coupled to an electric motor shaft for rotation with the steering wheel. A torque transducer senses a torque level for any application of rotational force applied to the steering wheel. An operator detector detects a presence or absence of an operator based on the sensed torque. The steering is controlled based on the detected presence or absence of the operator.
