Correlation of Electric Power Steering Vibration to Subjective Ratings 2000-01-0176

A study was conducted to investigate the subjective responses to steering wheel vibration caused by the electric power steering. The objective was to correlate the subjective responses to a measurable parameter that can be used to assess various design alternatives. Evaluations of six steering wheel vibration levels were performed in a stationary vehicle. Two rating methods were used. Results showed a wide range of acceptability of steering wheel vibration over the conditions evaluated. RMS angular acceleration and peak to peak torque at the steering wheel shaft correlated best with subjective ratings.
