Abstract: A control for a motor vehicle includes a transmission control and an engine control which are connected to one another through a communication channel. Functional units of the transmission control which are dependent on data of an engine and of a chassis of the motor vehicle, so-called engine-specific and chassis-specific functional units, are integrated into the engine control. Functional units having a function which is dependent on data of the transmission, so-called transmission-specific components, are contained in a computer-controlled gear shifting configuration. Data which are necessary for controlling the transmission are exchanged between the engine control and the gear shifting configuration through the communication channel 6. A shift point selection control, which can be constructed as a fuzzy control, is contained in the engine control.

Abstract: A control unit includes a transmission control unit and an engine control unit which are connected to one another through a communication channel. Functional units of the transmission control unit which are dependent on data from the engine and the chassis of the motor vehicle, so-called engine-specific and chassis-specific functional units, are integrated into the engine control unit. Functional units performing an operation that is dependent on data from the transmission, so-called transmission-specific components, are contained in a computer-controlled transmission ratio changing device. Data which are necessary for controlling the transmission, data for selecting or determining the transmission ratio of the transmission and configuration parameters for adapting the control unit to the respective motor vehicle, are exchanged between the engine control unit and the transmission ratio changing device through the communication channel.

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.
