METHODS AND APPARATUS TO MONITOR A CONDITION OF A BRAKING SYSTEM

Disclosed examples include measuring, via a sensor, a brake torque generated by a braking system; determining an energy output of the braking system based on a mechanical power output of the braking system, the mechanical power output based on the brake torque; determining an efficiency based on the energy output and an energy input, the energy input corresponding to an electrical power input of a motor of the braking system; detecting a condition of the braking system based on the efficiency; and outputting an indication representative of the condition.
