ABSTRACT:
A controlling system for a vehicle-carried internal combustion engine which prevents the rotational speed of the engine from rising excessively high even when an accelerator pedal is operated in a condition of a power transmitting system wherein it does not transmit the driving force of the engine from a transmission to a wheel of the vehicle whether the vehicle is in a stopping condition or in a driving condition. Such condition of the power transmitting system is detected by a driving force transmitting condition detector, and when such condition is detected, a controller controls a throttle valve of the engine so that the opening of the throttle valve may not exceed a predetermined throttle opening greater than an idling throttle opening irrespective of an operation amount of the accelerator pedal.
