Control for a motor vehicle drive having an automatic transmission

摘要

A motor vehicle drive has an engine and an automatic transmission. A control for the motor vehicle drive includes an engine control connected to the engine for controlling the torque of the engine. A transmission control is connected to the transmission for controlling shifting operations of the transmission and is connected to the engine control for sending a tripping signal to the engine control for changing torque and effecting a jerk-free shifting operation. Data are exchanged between the engine control and the transmission control preceding the tripping signal, by transmitting a proportion from the engine control to the transmission control for maximally reducing the torque of the engine for the shifting operation.
