Summary:

We have developed a new type of system to prevent disc brake squealing. The rotor vibration radiates the squeal noise, therefore if the rotor vibration can be stopped electronically, no squeal is generated. Based on this concept, the Electronic Control Canceling System for a Disc Brake Noise ( ECCN ) was developed for the opposed type brake which has four brake pistons. The ECCN consists of four piezoelectric elements and one electronic control unit, and can stop the low-frequency squeal of 24kHz by using a small amount of energy with the noise dynamometer and the test vehicle
