US 2023/0406273 A1 · WORK VEHICLE BRAKE ENERGY MANAGEMENT SYSTEM

Abstract

A work vehicle brake energy management system includes an axle speed sensor for monitoring a rotational speed of a work vehicle axle, a friction brake mechanism controllable to slow rotation of the work vehicle axle, a brake pressure sensor for measuring a brake apply pressure of the friction brake mechanism, and computer-readable memory. A processing subsystem is coupled to the axle speed sensor, to the brake pressure sensor, and to the computer-readable memory. The processing subsystem is configured to: (i) 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; and (ii) perform at least one predetermined brake overtemperature action in response to detection of a brake overtemperature event.
