ABSTRACT:
A control system for an automatic transmission includes a torque converter having input and output members through which driving power is transmitted. A lock-up clutch is provided in the torque converter for connecting the input and output members without intervention of hydraulic fluid. A multiple stage transmission gear mechanism is connected with the output member of the torque converter and has a plurality of shift gear stages. A shift control device shifts the shift gear stage in accordance with a vehicle operating condition. An engaging force control device controls an engaging force of the lock-up clutch in a manner such that a slip rate of the lock-up clutch is changed. Finally, an acceleration judging device judges a required acceleration, and the engaging force control device reduces the engaging force as the required acceleration is increasd. The control is made in a manner such that the driving power transmitted through the automatic transmission is continuously changed in accordance with the required acceleration. Both acceleration performance and fuel consumption performance can be improved.
