Abstract:
1. An automatic transmission control system comprising: a throttle operating amount detecting means for detecting an operating amount of a throttle due to a depression of an accelerator pedal by a driver; an engine rotating number detection means for detecting a rotating number of an engine in accordance with the operating amount of the throttle; and an automatic transmission means having therein a shift map defined by the operating amount of the throttle and the engine rotating number, for automatically controlling an actuation of upshift or downshift of a transmission based on the shift map, wherein the automatic transmission control system is provided with a depressing force changing means configured to provide a changing point of a depressing force in a midway of depression stroke of the accelerator pedal, the shift map including a changing point of the engine rotating number located at a boundary where an operating amount of the throttle corresponds to the depressing force changing point by the accelerator pedal, and wherein actuation of either the upshift or the downshift is controlled according to the shift map upon depression of the accelerator pedal beyond said depressing force changing point.
