Title: Controller of automatic transmission in power train
Inventor: TAKATORI KAZUHIRO
IPC: B60W10/10
Filed: 1997-11-04
Abstract: PROBLEM TO BE SOLVED: To eliminate a shock due to the simultaneous change-over of output characteristics of an engine and a transmission condition of an automatic transmission by inhibitting the change-over of a transmission condition of the automatic transmission while the engine is changing over the output characteristics. SOLUTION: An engine controller 8 sends an engine output characteristic change-over signal SF displaying the transition between stoichiometric air-fuel ratio operation and lean combustion operation to a transmission controller 14 while it is changing over these operations. The transmission controller 14 inhibits gear shift and a condition change of a torque converter to generate a signal inhibitting the change-over of a transmission condition of a transmission based on this engine output characteristic change-over signal SF. Consequently, even if it is judged that up shift transmission must be started and the torque converter must be moved to a lock up condition while engine output characteristics are being changed over, these processings are not done during the change-over of engine output characteristics, thereby preventing the occurrence of a shock.
