Abstract:
1. An internal combustion engine control system for vehicle comprising: power generation information monitor means for monitoring a power generation information including a voltage generated by a vehicle generator driven by means of an internal combustion engine; maximum engine speed limiting means for imposing a limit on a maximum engine speed of said internal combustion engine using a command signal; and secondary failure avoiding control means for feeding said command signal to said maximum engine speed limiting means and maintaining the voltage generated by said vehicle generator at a normal value to avoid a secondary failure due to abnormality in said generated voltage in the case where it is determined that said generated voltage exceeds a predetermined value, wherein the system includes electric load control means for ON/OFF controlling an electric load that receives a power supply from said battery; and said secondary failure avoiding control means controls said maximum engine speed limiting means and said electric load control means thereby controlling a revolving speed of said vehicle generator and an electric load, and maintains said generated voltage at a normal value to avoid the secondary failure, in the case where it is determined that said generated voltage exceeds a predetermined value.
