ABSTRACT:
In apparatus for controlling speed of a vehicle having an internal combustion engine and a power transmission mechanism as a controlled object, intake airflow, vehicle speed are detected and then an air-fuel mixture supply is controlled so that the vehicle travelling speed approaches a given cruising speed. The cruising speed is set in accordance with detected vehicle speed, while a target intake airflow is set to correspond to minimum fuel amount capable of maintaining the cruising speed on the basis of a pattern of correlation between fuel amount and intake airflow predetermined in correspondence with the cruising speed. The apparatus comprises an integral-added optimal regulator for determining feedback amount(s) of controlled variable(s) of the air-fuel mixture supply unit on the basis of operating equation(s) used for estimating internal state of the controlled object predetermined in accordance with a dynamic model of the system relating to the controlled object.
