Abstract
A running state control system for a motor vehicle comprises a traction control apparatus for controlling the traction of the motor vehicle, and a speed control apparatus for regulating a vehicle speed to a setting. The speed control apparatus is connected with the traction control apparatus via a signal line, and includes speed control correcting means. The speed control correcting means inhibit the speed control apparatus from outputting an opening operation signal to a mechanical throttle valve, and a down-shift signal to an automatic transmission while the traction control apparatus outputs a traction control signal. Additionally, the speed correcting means command the speed control apparatus to output a signal so as to slowly return the mechanical throttle valve when the operation of the speed control apparatus is interrupted while the traction control apparatus outputs the traction control signal.
