摘要： An automatic transmission which includes a clutch (6); a clutch actuator (7) for detecting and controlling a position of the clutch; a transmission (1); a transmission actuator (2) for driving the transmission; a vehicle speed detector (22) for detecting a vehicle speed; a throttle opening detector (11) for detecting a throttle opening; an automatic shift unit (30) including a gear shift map (30a, 30b) having a gear shift characteristic which is determined based on the vehicle speed and the throttle opening; a computer unit (30c) for computing an instant gear position of the transmission based on the vehicle speed and the throttle opening according to the gear shift map; a gear position selector (30d) for controlling the transmission actuator based on the instant gear position to upshift or downshift the transmission; a shift prohibit unit (40) for determining whether the instant gear position matches the previous gear position from a memory (40a) for a predetermined times in a predetermined period and, if they do not match for the predetermined times, invalidating the instant gear position and prohibiting any shift operation according to the gear shift map; and a shift determination unit (41) for establishing an upshift prohibit condition when the throttle opening is equal to or less than a predetermined value while releasing the upshift prohibit condition when the vehicle speed is low or the clutch is in a position toward disengagement from a half clutch position, or with a low-speed gears even if the throttle opening is equal to or less than the predetermined value.
