SYSTEM AND METHOD FOR BRAKING OF MACHINE

摘要

SYSTEM AND METHOD FOR BRAKING OF MACHINE 5 A method (700) of braking a machine (100) having an electric retarding system (214) and a friction brake system (302) is disclosed. The method (700) includes determining a desired retarding torque (400) based at least in part on an operator input (404). The method (700) further includes determining a maximum retarding torque (502) of the electric retarding system 10 (214) based at least in part on a maximum grid fan speed. The maximum grid fan speed is predetermined according to a noise requirement of the machine (100). The method (700) also includes actuating the electric retarding system (214) to supply an output torque (520) based on the desired retarding torque (400) and the maximum retarding torque (502). The method (700) includes actuating the 15 friction brake system (302) to supply a friction braking torque (600) if the output torque (520) is lesser than the desired retarding torque (400).
