Vehicle speed control system

A vehicle speed control system comprising:

• vehicle speed-detecting means for outputting a vehicle speed detection signal indicative of a vehicle speed which is a speed of a vehicle;
• display vehicle speed-calculating means for calculating a display vehicle speed for display on a vehicle speed-displaying section of the vehicle, based on the vehicle speed detection signal;
• controller vehicle speed-calculating means for calculating a controller vehicle speed which is distinct from the display vehicle speed, based on the vehicle speed detection signal;
• corrected vehicle speed-calculating means for calculating a corrected vehicle speed by correcting the controller vehicle speed with a correction value;
• correction component-updating and storing means for updating and storing a correction component with a predetermined control algorithm while causing a correlation between the corrected vehicle speed and the display vehicle speed to be reflected thereon in association with a vehicle speed parameter indicative of the vehicle speed, such that an error between the corrected vehicle speed and the display vehicle speed is reduced, and storing the updated correction component;
• correction value-calculating means for calculating the correction value using the stored correction component;
• target vehicle speed-determining means for determining a target vehicle speed which is a target of the corrected vehicle speed;
• and
• cruise control means for performing cruise control for controlling a motive power source of the vehicle, such that the corrected vehicle speed becomes equal to the target vehicle speed.
