The main idea from this paper is show a method to correlate the driver's subjective vibrational perception to numeric values of acceleration measured in the steering wheel. These studies came from a task realized during the development of a vehicle current in production. During the development period of this vehicle, a specific vibration was verified by subjective evaluations in the steering wheel, presenting a rotational movement. The intensity of this vibration is considered not acceptable considering the final consumer perception. From this assumption, a simplified method was used to measure this vibration and after this correlate it to the drivers' perception. The method consists in measuring the acceleration in the Y axis, tangent to the steering wheel, with the accelerometer at 12:00h position.
