ABSTRACT:
An internal combustion engine control system for vehicle prevents an electronic device from being damaged due to over-voltage failure of a generator, and enables the vehicle to continue to travel. Over-voltage failure of a vehicle generator (3) is detected from a voltage generated by the vehicle generator (3) and a voltage of a battery (4). When detecting any over-voltage failure, a maximum engine speed limiting apparatus (13) for preventing over speed of an internal combustion engine (1) is controlled to suppress the engine speed. Any electric load that consumes a relatively large current and does not make the traveling dangerous such as headlight (5) or heater heating wire (6) is applied to suppress the over-voltage. The electric load to be applied is increased or decreased depending on magnitude of the over-voltage. Thus the vehicle can continues traveling even if any over-voltage failure occurs.
