Abstract This paper proposes a novel hybrid power-split transmission to drive hydraulic implements in construction machinery. The highly efficient power-split hybrid transmission is combined with displacement controlled (DC) actuators to eliminate throttling losses within the hydraulic system and achieve higher fuel savings. The architecture design, sizing and power management are addressed. Simulation results considering a realistic truck-loading cycle on a mini excavator demonstrate the feasibility of the idea. A systematic comparison between the proposed system and the previously developed series-parallel hybrid is also carried out. The paper compares engine operation and fuel consumption of the previously mentioned hybrid system with the original non-hybrid load-sensing machine. It is shown that by implementing an efficient engine operation control, the proposed system can achieve up to 60.2% improvement in fuel consumption when compared to the original machine and consume 11.8% less than the previously developed series-parallel hybrid with DC actuation. Other advantages of the proposed solution include a much steadier engine operation, which opens to the possibility of designing an engine for optimal consumption and emissions at a single operating point as well as greatly reduce pollutant emissions. A steadier prime mover operation should also benefit fully electric machines, as the battery would not be stressed with heavy transients.

Abstract This paper presents a novel transmission mechanism for use in a parallel hybrid vehicle. A parallel hybrid vehicle typically employs two or more power sources to drive a vehicle. For such a vehicle to function properly, a non-conventional transmission mechanism and a microprocessor-based controller are needed to manage the power flow among the various power sources. The transmission mechanism described in this paper can provide a parallel hybrid with thirteen clutching conditions that can be grouped into five major modes of operation, namely, electric motor mode, power mode, CVT/charging mode, engine mode, and regenerative braking mode. The kinematics, statics, and power flow of each mode of operation are analyzed. A numerical example is used to illustrate the principle of operation. Furthermore, a clutching sequence control logic is developed.
