Creep-groan in vehicles is a low frequency vibration problem that occurs at low brake pressures and extremely low speeds. Noise, Vibration and Harshness (NVH) problems in brakes in general and creep-groan in particular manifest in different forms. Creep-groan is an example of self-excited vibration caused by stick-slip phenomenon. Most researchers to date have been concentrating on the characteristics between the friction material and the contacting surfaces and its effect on creep-groan vibration. This paper, instead, describes creep-groan and its relationship to vehicle dynamics by looking at the suspension response to creep-groan and presents a solution to reduce effects due to creep-groan vibrations.
