OSTI ID:5981393
An automatic transmission system for vehicles powered by an internal combustion engine is described which consists of: a gear-change mechanism connected to an internal combustion engine and adapted to operate in response to an electric signal; means for outputting at least one condition signal indicative of an operating condition of the internal combustion engine at each instant; a first detection means for detecting a gear position of the gear-change mechanism at each instant; a selector having at least a drive position for allowing automatic gear-change operation over a plurality of gear positions of the gear-change mechanism and a gear-holding position provided adjacent to drive position; an output means responsive to the operation of the an operation lever of the selector for outputting a command signal indicating a position at which the operation lever for selecting a desired operation mode is set; a storage means for storing a plurality of sets of map data corresponding to a plurality of gear change maps; a second detection means responsive to an output from the first detection means a map selecting means responsive to the command signal and an output from the second detection means for selecting a predetermined set of map data corresponding to the command signal; a control means responsive to the condition signal for controlling the operation of the gear-change mechanism in accordance with the set of map data selected by the map selecting means.
