Abstract
A machine can include an electric powertrain configured for electrical power and which includes a transmission. The transmission may be operatively associated with a hydraulic system that includes a hydraulic pump and a pressure relief valve disposed between the pump and the transmission. To reduce noise generated by the pressure relief valve, operation of the pressure relief valve may be regulated according to a pump function that relates operation of the pressure relief valve with a sensed pump operation associated with the hydraulic pump.
