Abstract
A work vehicle locking differential energy management system includes axle speed sensors for monitoring the rotational speeds of axle half-shafts. The axle half-shafts are coupled through a locking differential, which contains a differential clutch mechanism. A processing subsystem is configured to: (i) when the locking differential is placed in a locked state, calculate a differential lock force applied to the clutch mechanism, and calculate a differential slip speed from a disparity in the rotational speeds of the axle half-shafts; (ii) estimate an internal temperature of the clutch mechanism based, at least in part, on the differential lock force and the differential slip speed; (iii) detect differential overtemperature events during which the internal temperature of the clutch mechanism exceeds a first critical temperature threshold; and (iv) perform at least one differential overtemperature action in response to detection of a differential overtemperature event.
