1. A brake energy management system onboard a work vehicle having a work vehicle axle, the brake energy management system comprising:
an axle speed sensor configured to monitor a rotational speed of the work vehicle axle;
at least one friction brake mechanism controllable to slow rotation of the work vehicle axle;
a brake pressure sensor configured to provide data indicative of a brake apply pressure of the friction brake mechanism;
a computer-readable memory; and
a processing subsystem coupled to the axle speed sensor, to the brake pressure sensor, and to the computer-readable memory, the processing subsystem configured to:
utilize data from the axle speed sensor and from the brake pressure sensor to detect brake overtemperature events during which an internal brake temperature of the friction brake mechanism exceeds at least a first critical temperature threshold stored in the computer-readable memory;
perform at least one predetermined brake overtemperature action in response to detection of a brake overtemperature event; and
determine whether an autobraking system is presently automatically braking the work vehicle axle utilizing the friction brake mechanism and, if the autobraking system is automatically braking the work vehicle axle, command the autobraking system to reduce the brake apply pressure of the friction brake mechanism when the internal brake temperature of the friction brake mechanism exceeds at least the first critical temperature threshold.
