Abstract
A vehicle speed control system includes a first electronic control unit for transmitting a difference between actual and target vehicle speeds and control constants that vary depending on the vehicle speed difference when it determines fulfillment of vehicle speed control conditions, and a second electronic control unit for performing the vehicle speed control based on the vehicle speed difference and control constants received through a communication line. Change of the control constants for adjustment of a vehicle speed control function of the system can be easily carried out by changing the control constants stored in the first electronic control unit.
