摘要

A device for monitoring an electronic control system, for an internal combustion engine comprises two computers 1, 2 at least one of them having a monitoring device 5, 6 to detect abnormal operation. in accordance with the output signals from the monitoring device (3), a logic circuit 7 is influenced so that the output signals of either the main computer or the subsidiary computer are fed to an actuator 8. The monitoring device output is also connected to an input of the second computer so that it can react appropriately in the event the monitor detects a failure. The monitor output can be fed back to its own computer to initiate a reset routine, the computer may be connected directly together 12 or via a storage device 9, 10 for data exchange, and further internal monitors 13, 14 may also be provided. <IMAGE>
