Abstract: Systems and methods for fault toleration actuation include an actuator with a position. A first sensor measures a first parameter associated with the actuator. A second sensor measures a second parameter associated with the actuator. A sensor fusion module receives data from each of the first and second sensor and executes a sensor fusion process on the data received to estimate the position of the actuator. A fault detection module is configured to receive data from the first and second sensor, to receive sensor fusion data from the sensor fusion module, to compare the data received from the first and second sensor with the sensor fusion estimate, to identify an error in the data received from either of the first or second sensor based on the comparison, and to determine a fault exists in the first or second sensor based on the error.

Abstract: An insert for a casting mold used to produce a sound dampening rotor of a caliper disc brake is provided. The insert includes a ring having an inner diameter, an outer diameter and at least one tab. The insert also includes an inner core made from a refractory material, the inner core being adjacent to the ring. The tab of the ring is operable to position the ring relative to the inner core. Furthermore, the ring and the inner core together can be placed within the casting mold and afford for the desirable and accurate placement of the sound dampening ring within a cast sound dampening composite rotor of a caliper disc brake.
