Abstract

A control configuration for a motor vehicle includes an engine control and a transmission control which are connected to one another through a communication channel. A transmission is shifted by using electrohydraulic pressure control valves for actuating friction elements in the transmission. The transmission control is mounted at a transmission housing. Solenoids of the electrohydraulic pressure control valves are integrated into the transmission control. Sensor signals which are to be evaluated by the transmission control are transmitted by sensors to the transmission control wirelessly.
