A lubricating system 42 and a method for lubricating a vehicle transmission, the system comprising a lubricating circuit 44 for supplying lubricant to a transmission component such as a final drive unit 26, the circuit 44 including a reservoir 46, a supply line 48 for supplying lubricant from the reservoir 46 to the transmission, a return line 50 for returning lubricant from the transmission to the reservoir 46 and an electrical pump 52 for pumping lubricant from the reservoir 46 to the transmission. A controller 56 is arranged to monitor a vehicle condition and configure the electrical pump 52 to pump a predetermined flow rate of lubricant to the transmission based on a current driving condition and or lubricant temperature, the driving condition including one or more of, speed, torque, lubricant temperature, vehicle inclination and fuel cut signal. The lubricating system may be a dry sump configuration and the transmission include one or more of, pinion bearing, differential case bearing or a pinion/ring gear mesh point of a final drive unit. The lubricating system may further incorporate an oil contaminant measuring sensor 58 that through the controller 56 emits a warning if the contaminant exceeds a threshold level. |
