Abstract: A system includes a drive system (e.g., a vehicle drive system) and a controller. The drive system includes a motor and/or engine and a rotational component (e.g., gear or bearing) that is rotated during operation of the drive system. The controller is configured to receive operational information of the drive system and to determine an estimated lifespan of the rotational component based at least in part on torque, speed, and time information associated with the rotational component. The controller is further configured to control the drive system or another vehicle system based on the estimated lifespan. For example, for a bearing, the controller may be configured to track time of operation in different speed ranges and/or torque ranges, for determining a corrected speed and/or a corrected force, respectively, that is used for determining the estimated lifespan.
