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.

Abstract: A starter protective device is provided which is capable of accurately determining the commencement of overrunning (i.e., timing of the commencement of starting of an engine) even in the presence of variations in the cycle of fluctuations in a battery voltage, noise and so on, thereby to prevent a starter from being overrun after starting of an engine in a reliable manner. The starter protective device includes an overrunning determination section 15 for determining when the starter motor 4 commences overrunning; and a starter motor cut-off section for interrupting the main contactor 3 when it is determined that the starter motor 4 commences overrunning. The overrunning determination section 15 detects a change over time of the battery voltage BV after the starter switch 2 has been turned on, and determines that the starter motor 4 commences overrunning when the battery voltage VB remains unchanged without any increase or decrease over a predetermined time T.

The second comparator (6) outputs a field current interrupt signal (C3) when the ambient temperature (T) exceeds a second activation temperature (TP2) while resetting the signal (C3) when the temperature (T) becomes lower than the second activation temperature (TP2).
