ABSTRACT:
A throttle valve control system for a vehicle-mounted internal combustion engine, whereby engine operating parameters relating to engine load are detected, and a target value of a first engine operating parameter is established in accordance with an engine rotational speed, for example a target value which will endure minimum fuel consumption. The throttle valve is driven towards a control opening angle which is determined such as to reduce an amount of deviation of an actual value of the first engine operating parameter from the target value, but is held below an upper limit opening angle which is determined in accordance with an engine operating parameter.
