Prediction of Fuel Consumption Reduction of a Recreational Vehicle by Electrification of Its Clutch Transmission

Automated Manual Transmission based on hydraulic clutch actuation gives high performances and comfort to a recreational vehicle. However, its continuous power consumption is too high to be considered in a hybrid version of a recreational vehicle. Hence, the objective is to evaluate the fuel consumption reduction achieved by the clutch electrification. The method is based on numerical models of energy consumption comparison between an actual hydraulic clutch actuator and a new electrified clutch actuator. Both simulated technologies are evaluated for preestablished clutch operational cases and a normalized driving cycle. Relative power consumption of each technology on this last cycle predicts a fuel consumption reduction of 6.2% thanks to the clutch electrification.
