description	A control system to determine a hands on wheel (HOW) condition is provided. The control system includes a sensor that monitors an amount of applied torque exerted upon a hand wheel, and a control module for monitoring the sensor. The control module includes a notch filter to attenuate a normal column mode frequency from the amount of applied torque to produce a filtered torque signal. The normal column mode frequency represents a range of vibrational modes of the hand wheel based on a hands off wheel condition. The control module includes a state detector to receive the filtered torque signal from the notch filter. The state detector determines if the HOW condition exists based on if the filtered torque signal exceeds an ON threshold torque value.
