ABSTRACT:
The invention relates to a drive train controller of a motor vehicle which has an engine and an automatic transmission. The drive train controller has an engine controller for controlling variables affecting engine torque and a transmission controller for controlling shifting events of an automatic transmission. There is an interface interconnecting the transmission controller and the engine controller for allowing constant communications between the transmission controller and the engine controller. The transmission controller transmits a correction term M.sub.kor to the engine controller over the interface for controlling a magnitude of the engine torque. The transmission controller transmits a time constant to the engine controller via the interface for controlling the dynamic behavior of the engine torque. In this manner, the transmission shifts smoothly between gears.
