Claim:
1. A planetary differential continuously variable transmission, comprising: a first drive input ring gear having internal teeth; a planetary differential connected to the first drive input ring gear, the planetary differential including a planet gear carrier, first planet gears, second planet gears, a first sun gear, and a second sun gear, teeth of each of the first planet gears are engaged with the internal teeth of the first drive input ring gear and the teeth of each of the first planet gears engage teeth of the first sun gear, and the teeth of each of the first planet gears also engage teeth of corresponding ones of each of the second planet gears, and the teeth of each of the second planet gears engage teeth of the second sun gear; a first electric machine having a first stator and a first rotor, the first rotor is connected to the first drive ring input ring gear; a second electric machine having a second stator and a second rotor, the second rotor is connected to the planet gear carrier that acts as a second drive input; and a one way clutch located between the second stator and the second rotor to limit a reverse rotation of the second rotor.
