A method and a system exchange data between a program-controlled device, in particular a microcontroller, and a logic circuit. A control signal is transmitted from the program-controlled device to the logic circuit along a first line. A bidirectionally usable, second line is placed in the dominant state by the logic circuit if a data transmission is to be made by the logic circuit.

Method and system for exchanging data

In a method for the production of actuator signals as a function of sensor signals in an open-loop and/or closed-loop control system, the sensor signals are read into a data processing device and converted into internal input signals. The internal input signals are evaluated together with stored status information with the use of predetermined functions, whereby internal output signals and possibly new status information to be stored result. Actuator signals are derived from the internal output signals and fed to at least one actuator.
