Control system for automatic transmission

摘要

A control system for an automatic transmission comprises a constant mesh type gear speed change mechanism for transmitting the output torque of an engine, and a plurality of frictional engagement elements adapted to be separately applied/released for switching torque transmission passages of the gear speed change mechanism to set a predetermined gear stage. The control system is provided with a torque control function to control the drive force of a vehicle by slipping the frictional engagement elements other than those setting a gear stage while the vehicle is running in the state with the predetermined gear stage being set by applying predetermined ones of the frictional engagement elements.
