Most hybrid vehicles employ the continuously variable transmission(CVT) currently as their choice of the transmissions. Recently, an automated geared transmission(AGT) or dual clutch transmission(DCT) is being tried for some hybrid vehicles for the better fuel economy than CVT hybrid. However, this AGT or DCT is using the automated clutches which require the hydraulic power in addition to the slippage in the clutch plate invoking some energy loss as well as wear. Also, they require a motor with significant power to match to the engine power.
The clutchless geared smart transmission(CGST) has no clutch and the clutch function is performed by the planetary gear system controlled by a motor/generator. The hybrid vehicles using CGST are expected to have some merit in durability, fuel efficiency, and cost as they don"t have clutches which cause wear and slippage. The motor used for the clutch function is working in synergy(power merge) with the engine in driving the vehicle. The hybrid system suggested here may use only the motor with the engine off for slow vehicle speed and the engine is mobilized only when its power is required. Also, the hybrid vehicle here can be either mild hybrid or full hybrid by adopting a different capacity of battery with much smaller motor/generator due to the planetary gear system compared to the other hybrid vehicles.
In this study, we are going to demonstrate the positive prospect of our new CGST hybrid system by comparing the system with AGT hybrid or DCT hybrid in practical aspects.
