Abstract
A method of detecting a failure of a brake actuator is provided. The method includes monitoring an angular position of a motor controlling the brake actuator. Also included is monitoring a linear position of a linear translation arrangement of the brake actuator, wherein the linear position of the linear translation arrangement is controlled by a gear assembly in communication with the motor and the linear translation arrangement. Further included is comparing the linear position of the linear translation arrangement with the angular position of the motor. Yet further included is determining whether the linear position of the linear translation arrangement is within a predetermined range of linear positions corresponding to a plurality of angular positions.

A method of detecting a failure of a brake actuator comprising:
- monitoring an angular position of a motor controlling the brake actuator;
- monitoring a linear position of a linear translation arrangement of the brake actuator, wherein the linear position of the linear translation arrangement is controlled by a gear assembly in communication with the motor and the linear translation arrangement;
- comparing the linear position of the linear translation arrangement with the angular position of the motor;
- and
- determining whether the linear position of the linear translation arrangement is within a predetermined range of linear positions corresponding to a plurality of angular positions.
A braking system comprising:
- a support plate;
- at least one brake actuator operably coupled to the support plate, the at least one brake actuator including an actuator plate in communication with a gear assembly for converting rotational motion to linear motion of a linear translation arrangement;
- an angular position sensor for determining an angular position of a motor of the at least one brake actuator;
- a linear position sensor for determining a linear position of the linear translation arrangement;
- and
- a controller for determining whether the linear position is within a predetermined range of linear positions corresponding to a plurality of angular positions.
