CONTROL DEVICE FOR AUTOMATIC TRANSMISSION

摘要

PURPOSE:To suppress production of slip even if a throttle opening becomes large during TRC, in a control device for automatic transmission which is used in combination with an accelerating slip control device to prevent an excessive slip in starting and accelerating of a vehicle. CONSTITUTION:In a control device for automatic transmission which is provided on an internal combustion engine M4 with TRC(Traction Control) unit M3 which drives a throttle valve M2 to the closer side than a throttle position corresponding to the operation of an accelerator pedal M1, and performs gear- change processing of an automatic transmission M5 based on the opening of the throttle valve M2, a gear-change point alteration means M6 to change a gear-change point to a low engine speed side when the amount of operation of the accelerator pedal M1 comes over a specified limit during TRC is provided.
