    Abstract: A control apparatus (64) for a transmission. The transmission includes first and second transmission lines (7 8), (10, 11) disposed in parallel between an upstream transmission shaft (2) for receiving power from an engine (1) and a downstream transmission shaft (4) for transmitting the power to a traveling unit (53, 54); a hydraulic multiple disc transmission clutch (6) disposed transmission-wise upstream or downstream of the first and second transmission lines, the power of the upstream transmission shaft being transmitted via one of the first and second transmission lines to the downstream transmission shaft; a first gear change-speed mechanism (13) disposed between either the upstream transmission shaft or the downstream transmission shaft and the first transmission line, the first gear change-speed mechanism having a plurality of speed positions; a first actuator (35) for operating the first gear change-speed mechanism; a first friction clutch (9) incorporated in the first transmission line; a second gear change-speed mechanism (15) disposed between either the upstream transmission shaft or the downstream transmission shaft and the second transmission line, the second gear change-speed mechanism having a plurality of speed positions; a second actuator (37) for operating the second gear change-speed mechanism; and a second friction clutch (12) incorporated in the second transmission line. When the power is being transmitted via the first transmission line, a first controlling means operates the second gear change-speed mechanism into a predetermined speed position by means of the second actuator and operates the first friction clutch from a transmitting state to a non-transmitting state and simultaneously operates the second friction clutch from a non-transmitting state to a transmitting state, thereby to realize a progressive shifting of the transmission clutch from a transmitting state to a semi-transmitting state.

    Abstract: An automatic transmission control system for a transmission which is installed in a vehicle and whose torque converter is provided with a lockup mechanism; comprising a vehicle weight estimation device for estimating the weight of the vehicle; a gradient estimation device for estimating a gradient on which the vehicle is running; a standard lockup line selector for storing therein standard lockup lines which correspond respectively to the specified gear shift ratios of a speed change gear included in the transmission, and for selecting that one of the stored standard lockup lines which corresponds to the gear shift ratio in the present state of the vehicle; a lockup line corrector for correcting the selected standard lockup line in accordance with the estimated vehicle weight and the estimated gradient; and a lockup signal output device for deciding a timing of lockup "ON" or lockup "OFF" by the use of the corrected lockup line, and for delivering a lockup signal to the lockup mechanism (a lockup solenoid) at the decided timing. Since the lockup timing is varied in accordance with a running resistance, the drivability of the vehicle is enhanced.
