Proactive health-based transition to redundant subsystems
First Claim
1. A method for proactively transitioning performance of a functional operation from a primary subsystem to a secondary subsystem within a system having an electronic control unit (ECU) and the primary and secondary subsystems, the method comprising:
- receiving health management information via the ECU when the primary subsystem is actively performing the functional operation within the system and the secondary subsystem operates in a standby mode, wherein the health information is indicative of a numeric state of health (SOH) of the primary subsystem;
comparing the numeric SOH to a calibrated non-zero threshold SOH; and
commanding, via the ECU, a transition of the performance of the functional operation to the secondary subsystem and placing the primary subsystem in the standby mode when the numeric SOH is less than the calibrated non-zero threshold SOH.

Abstract
A method proactively transitions performance of a functional operation from a primary subsystem to a secondary subsystem within a vehicle or other system having an electronic control unit (ECU). The method includes receiving health management information via the ECU when the primary subsystem is actively performing the functional operation within the system and the secondary subsystem operates in a standby mode, wherein the health information is indicative of a numeric state of health (SOH) of the primary subsystem. The method also includes comparing the numeric SOH to a calibrated non-zero threshold SOH, and then commanding, via the ECU, a transition of the performance of the functional operation to the secondary subsystem and placing the primary subsystem in the standby mode when the numeric SOH is less than the calibrated non-zero threshold SOH. A vehicle executes the method via the ECU.

11. A vehicle comprising:
-
a primary subsystem; a redundant secondary subsystem; and an ECU in communication with the primary and secondary subsystems, wherein the ECU is configured to; receive health management information when the primary subsystem is actively performing a functional operation within the vehicle and the secondary subsystem operates in a standby mode, the health information being indicative of a numeric state of health (SOH) of the primary subsystem; compare the numeric SOH to a calibrated non-zero threshold SOH; command a transition of the performance of the functional operation to the secondary subsystem and place the primary subsystem in the standby mode when the numeric SOH is less than the calibrated non-zero threshold SOH. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
