CONTROL SYSTEM AND CONTROL METHOD FOR REDUCING RATTLE NOISE OF BRAKE CALIPER

摘要

A control system for reducing rattle noise of a brake caliper may include a wheel speed sensor configured to detect a wheel speed of each wheel to which a caliper device is mounted, a controller configured to determine a vibration level value according to a road surface state by processing and analyzing a wheel speed signal received from the wheel speed sensor, and, when the road surface state of the road is determined as one in which unevenness exists, output a control signal for applying oil pressure for preventing rattle noise to a wheel cylinder of a brake device, a braking driver configured to generate and supply the oil pressure for preventing rattle noise according to the control signal output from the controller, and the wheel cylinder of the brake device, to which the oil pressure for preventing rattle noise, which is supplied by the braking driver, is applied.

1. A control system for reducing rattle noise of a brake caliper, the control system comprising:
a wheel speed sensor configured to detect a wheel speed of each wheel to which a caliper device is configured to be mounted; a controller configured to determine a vibration level value according to a road surface state of a road on which a vehicle is driven by processing and analyzing a wheel speed signal received from the wheel speed sensor, and, when the road surface state of the road is determined as a road surface state in which unevenness exists from the determined vibration level value, output a control signal for applying oil pressure for preventing rattle noise to a wheel cylinder of a brake device provided to the wheel; a braking driver configured to generate and supply the oil pressure for preventing rattle noise according to the control signal output from the controller; and the wheel cylinder of the brake device, to which the oil pressure for preventing rattle noise, which is supplied by the braking driver, is applied.
