Abstract
A vehicle speed control method comprises the steps of calculating a time difference between a predetermined period of time corresponding with a desired speed and the actual period of time corresponding with the actual vehicle speed, calculating a time difference between the respective actual periods of time, detecting each value of the calculated time differences in its low resolution related to a predetermined low speed range when the actual period of time represents a value in the predetermined low speed range, detecting each value of the calculated time differences in its high resolution related to a predetermined high speed range when the actual period of time represents a value in the predetermined high speed range, and producing a correction signal related to one of the detected values such that an output signal is produced to actuate a control element so as to control the quantity of fuel supplied into a combustion engine.
