Abstract:
A monitoring system includes a hydraulic accumulator including a piston movably disposed therein. At least one seal encompasses the piston. A first pressure sensor is configured to monitor pressure of a first fluid in a first chamber. A second pressure sensor is configured to monitor pressure of a second fluid in a second chamber. A first temperature sensor is disposed in the first chamber and configured to monitor the temperature of the first fluid. A second temperature sensor is disposed in the second chamber and configured to monitor the temperature of the second fluid. An electronic control unit is in communication with the sensors and programmed to in response to receiving pressure signals from the pressure sensors and temperature signals from the temperature sensors, determine a wear volume of the at least one seal; and compare the wear volume of the at least one seal to a predetermined threshold wear volume of the at least one seal to determine the remaining useful life of the hydraulic accumulator.

Claim (Index 1):
A system for monitoring a hydraulic accumulator, the system comprising:\n a hydraulic accumulator including a first chamber and a second chamber; a piston movably disposed in the hydraulic accumulator, the piston separating the first chamber from the second chamber; at least one piston seal encompassing the piston; a first pressure sensor disposed in the first chamber proximate the piston seal, the first pressure sensor configured to monitor pressure of a first fluid in the first chamber; a second pressure sensor disposed in the second chamber proximate the piston seal, the second pressure, sensor configured to monitor pressure of a second fluid in the second chamber; a first temperature sensor disposed in the first chamber proximate the piston seal, the first temperature sensor configured to monitor the temperature of the first fluid; a second temperature sensor disposed in the second chamber psoximate the piston seal, the second temperature sensor configured to monitor the temperature of the second fluid; and an electronic control unit including an algorithm, the electronic control unit in communication with the first pressure sensor, the second pressure sensor, the first temperature sensor and the second temperature sensor, the algorithm of the electronic control unit programmed to:\n responsive to receiving pressure signals from the first and the second pressure sensors and temperature signals from the first and second temperature sensors, determine a wear volume of the at least one  - piston seal, and \n compare the wear volume of the at least one piston seal to a predetermined threshold wear volume of the at least one piston seal to determine a remaining useful life of the hydraulic accumulator,
