CONTROL DEVICE OF AUTOMATIC TRANSMISSION

摘要

PROBLEM TO BE SOLVED: To prevent a driver from feeling discomfort or having a sense of incongruity by controlling the switching between activation and non-activation of lockup in a follow-up travel control function. SOLUTION: A lockup control part 15 refers to the characteristic map I which is a characteristic map of lockup control at normal time preliminarily set in response to a vehicle speed V and a throttle openingθth when an automatic travel control device 23 is not actuated, and refers to the characteristic map II which is a characteristic map of lockup control preliminarily set through a change to the higher speed side than the characteristic map I when the automatic travel control device 23 is actuated so that a lockup activation vehicle speed Von and a non-activation vehicle speed Voff in the throttle openingθth at that time are set. Activation and non-activation of a lockup clutch 6 are controlled by the lockup activation vehicle speed Von and non-activation vehicle speed Voff read from the characteristic map I or characteristic map II.
