Abstract

A vehicle speed control system capable of improving all of calculation accuracy of corrected vehicle speed, controllability of cruise control, and safety and marketability of the system. Vehicle speed control system includes FI ECU and meter ECU. The meter ECU calculates meter vehicle speed, and transmits the same to the FI ECU via CAN communication network. The FI ECU calculates controller vehicle speed, calculates CC vehicle speed by correcting the controller vehicle speed with a vehicle speed correction coefficient, updates and stores local correction coefficients such that the difference between the speeds is reduced while causing correlation between the speeds to be reflected thereon according to the controller vehicle speed, calculates the vehicle speed correction coefficient using the stored coefficients, determines a target vehicle speed, and performs cruise control such that the CC vehicle speed becomes equal to the target vehicle speed.
