Abstract
A vehicle speed control method comprises the steps of dividing a frequency corresponding with the actual speed by a frequency divisional ratio determined inversely proportional to a desired speed, producing a timing signal with the divided frequency, calculating a time difference between a predetermined time period corresponding with a desired speed and the total of constant time periods defined by a time period of the timing signal, calculating a time difference between both the totals of constant time periods defined by respective time periods of the preceding and following timing signals, and producing a correction signal related to the calculated time differences such that an output signal is produced to actuate a control element so as to control the quantity of fuel supplied into an engine.
