First Claim
1. A vehicle comprising:
- a vehicle control system that includes processor circuitry, a system memory, and a system communications interface; and
a vehicle component, having a component memory and a component communications interface communicatively coupled with the system communications interface, wherein the component memory is configured to store a plurality of different accumulated wear parameter values for the vehicle component and an operating age that is indicative of a duration of use of the vehicle component, each of the accumulated wear parameter values representing an amount of accumulated wear of the vehicle component while the vehicle component operates in a respective operating range of a plurality of different operating ranges,wherein the system memory stores instructions that, while executed by the processor circuitry of the vehicle control system, direct the vehicle control system to;
update the accumulated wear parameter value for one or more of the different operating ranges and the operating age of the vehicle component during operation of the vehicle component;
determine projected wear parameter values of the vehicle component for the operating ranges, the projected wear parameter value determined for each of the operating ranges based on the operating age of the vehicle component that is updated and a designated growth rate of wear for the vehicle component that is associated with the respective operating range;
determine available wear parameter values for the vehicle component for each of the operating ranges based on the accumulated wear parameter value of the respective operating range and the projected wear parameter value of the respective operating range; and
perform a first corrective action for the vehicle based on at least one of the available wear parameter values,wherein the vehicle component comprises an alternator;
wherein each of the plurality of operating ranges comprises a range of pole bolt speeds, andwherein each of the available wear parameter values comprises a number of available pole bolt speed cycles of the alternator.

Abstract
Aspects of the subject technology relate to systems and methods for monitoring component wear to prevent premature component failure. A control system for a system having one or more mechanical or electronic components may include a life manager that monitors accumulated wear of the one or more components. The life manager may provide an alert and/or limit system operations when the accumulated wear exceeds a limit. The limit may be dynamically determined based on an operating age of the component. The limit may also be defined as a matrix of limits, each defined for a range of a particular operating condition of the component. Operating conditions may include an applied torque range for a vehicle wheel or a thermal cycle temperature range for an electronic switching component.
