Title:
CONTROL DEVICE OF DISC BRAKE
Document Type and Number:
Japanese Patent JP2019138433
Kind Code:
A
Abstract:
To provide a control device of a disc brake which can elongate a life of a disc rotor by polishing the disc rotor on the basis of a wall thickness of the disc rotor.SOLUTION: A control device of a disc rotor for generating a brake force by pressing a brake pad to a disc rotor by an actuator comprises: a disc rotor wall thickness calculation part for calculating a wall thickness of the disc rotor at each rotation position; and a control part for controlling brake pressure being pressure for pressing the brake pad to the disc rotor by the actuator. When a minimum value of the wall thickness of the disc rotor is not smaller than a prescribed first threshold, and when a wall thickness difference of an entire face of the disc rotor is larger than a prescribed second threshold, the control part polishes the disc rotor by boosting the brake pressure according to a change of the wall thickness of the disc rotor.SELECTED DRAWING: Figure 1
