1. A variable transmission comprising: an input shaft;a planetary gear set drivingly engaged with the input, shaft;a first brake mechanically coupled to a ring gear of the planetary gear set;a variator comprising a variator carrier assembly, a first ring assembly, and a second ring assembly, the var
1. A variable transmission comprising: an input shaft;a planetary gear set drivingly engaged with the input, shaft;a first brake mechanically coupled to a ring gear of the planetary gear set;a variator comprising a variator carrier assembly, a first ring assembly, and a second ring assembly, the variator carrier assembly mechanically coupled to the ring gear of the planetary gear set;and a second brake mechanically coupled to a sun gear of the planetary gear set and to the first ring assembly of the variator;the second ring assembly of the variator drivingly engaged to an output of the variable transmission. 2. The variable transmission of claim 1, comprising a continuously variable mode and an infinitely variable mode. 3. The variable transmission of claim 1, wherein when the first brake is engaged and the second brake is disengaged, the ring gear of the planetary gear set and a carrier of the variator are held fixed, thereby engaging a continuously variable mode. 4. The variable transmission of claim 2, wherein power passes through the sun gear of the planetary gear set to the first ring assembly when the transmission is in continuously variable mode. 5. The variable transmission of claim 1, wherein when the second brake is engaged and the first brake is disengaged, the sun gear of the planetary gear set and the first ring assembly are held fixed, thereby engaging an infinitely variable mode. 6. The variable transmission of claim 5, wherein power passes through the ring gear of the planetary gear set to a carrier of the variator in the infinitely variable mode. 7. The variable transmission of claim 1, wherein in the infinitely variable mode, the variator provides a reverse function, a standstill function and a low speed function. 8. The variable transmission of claim 2, wherein a transition between continuously variable mode and infinitely variable mode is accomplished by simultaneously releasing one of the first brake and the second brake while applying the other of the first brake and the second brake. 9. The variable transmission of claim 1, wherein the first brake is an electric brake. 10. The variable transmission of claim 1, wherein the second brake is an electric brake.
