methods and systems are provided for controlling braking to avoid groan noise in a braking system. the system has a brake actuator configured to apply a friction force to a moving member, a conduit system coupled with the brake actuator, an inlet valve in the conduit system configured to control fluid pressure delivered to the brake actuator, and an outlet valve in the conduit system configured to control fluid pressure released from the brake actuator. the system includes a controller to monitor for an upper target pressure condition in the braking system, wherein the upper target pressure condition is associated with a noise zone; and operate, when the upper target pressure is detected and in a noise zone avoidance mode, the inlet valve and the outlet valve to avoid brake pressures that generate a brake noise from the friction force. | |||
