Abstract
This microcomputer system can be used, for example, in a regulator for internal combustion engines for controlling and regulating the fuel injection and other functions in a motor vehicle in dependence on operating magnitudes. Exemplary controlled functions include engine revolutions, charging pressure, gas pedal position, etc. The controlled functions are determined with the aid of sensors connected with the microcomputer system. The outputs of the microcomputer are connected with servo members, signal displays or the like, which may be energized by drive circuits. The system functions are distributed over the individual microcomputers (1, 2, 3), and a parameter storer (5) is provided for, for example, motor-specific and vehicle-specific data. The system includes individual microcomputers (1, 2, 3) and a parameter storer (5), preferably constructed as a pluggable module, which are connected to a combined, bidirectional address and data bus (4) isolated from the microcomputer-internal address and data buses, and is designed exclusively for the exchange of data among the digital components of the system. The system is extremely resistant to electromagnetic interference making it particularly suitable for motor vehicles.
