Abstract:
1. A continuously variable transmission, comprising: a driven element; at least one operator input device configured to transmit a transmission operating mode request; at least one other operator input device configured to transmit a driven element output request; at least one sensor configured to sense at least one parameter indicative of an operating condition of the transmission; and a controller configured to regulate an output of the driven element by selecting selection of, based on the transmission operating mode request, a map from a plurality of maps stored in a memory, and by selection of one of a plurality of sub-maps from the selected map based on the driven element output request and the at least one parameter, wherein the plurality of maps includes a forward base control map and a reverse base control map, the forward base control map includes a forward propulsion, a forward retarding, and a forward directional shift sub-map, and the reverse base control map includes a reverse propulsion, a reverse retarding, and a reverse directional shift sub-map.
