摘要 |
A safety device for a controlling unit of an internal combustion engine controlled by a microcomputer includes the following circuits: (a) a source of stabilized voltage which may be subject to fluctuations; (b) a first monitoring circuit responsive to voltage breaks in the voltage source to block the controlling unit for the duration of respective voltage breaks; (c) a second monitoring circuit responsive to the operability of the microcomputer to block the controlling unit for the duration of the resetting time of the microcomputer when a non-operative condition of the microcomputer is detected.
