They imaged the possibility but didn't have the electronic controls to make it work outside of a lab.

TRW tested a hybrid with a power-split device very similar to the Toyota Hybrid Synergy Drive way back in the 60's. It was granted a patent in 1971: US 3566717A. It has an ICE engine, two motor / generators and the same power modes as the Toyota system.
