  • Virtual vehicle transmission test cell
    Patent number: 6754603
    Abstract: The virtual vehicle transmission test cell includes an electric motor which simulates a fuel driven engine, an output motor which simulates the load a transmission experiences in a vehicle, and an environmental element which controls the ambient environment of the transmission and the temperature of the transmission oil within the transmission. The virtual vehicle transmission test cell reduces in-vehicle testing, reduces testing with fuel-driven test cells, and enables development of a transmission design before a corresponding engine is completed and built for testing.
