Abstract

A method for reducing or mitigating the effects of vibration in a vehicle brake system, particularly those that can lead to brake groan or other unwanted noise. According to an exemplary embodiment, when the vehicle brake system detects certain vibratory conditions, it makes slight braking adjustments (e.g., adjustments to fluid pressure, brake force, brake torque, etc.) that are aimed to address the brake groan. The vehicle brake system can then determine the effectiveness of the braking adjustments and, if need be, make additional braking adjustments. The method is particularly well suited for use with brake-by-wire systems, but can be used with a number of different vehicle braking systems.
