EINRICHTUNG ZUR STEUERUNG DER KRAFTSTOFFEINSPRITZUNG EINER BRENNKRAFTMASCHINE

摘要

A device comprises two processors 11, 21, for example for controlling the injection of fuel into an internal combustion engine. Variables are detected (2) and at least one of the two processors calculates a manipulated variable for supplying (6) to a peripheral unit and controlling the fuel injection. The first processor 11 determines the manipulated variable in dependence on data, more particularly numerical data, calculated by the second processor 21. Each processor 11, 21 may comprise first and second computers 12,13; 22, 23 and a monitor computer 14, 24. The processors may be connected by a data line having a dual-port RAM 8. The manipulated variable calculated by the first computer 12 may be compared in the monitor computer 24 with the manipulated variable calculated by the second computer 23 to detect faults and actuate a warning light 10.1. A defective processor may be switched off and the other allowed to continue operation. Anti-skid braking systems and robots may alternatively be controlled by the device. <IMAGE>
