1. A distance control apparatus for controlling a space between two traveling vehicles, said control apparatus comprising:
- acceleration/deceleration means for accelerating and decelerating a vehicle;
relative speed detecting means for obtaining a relative speed between two traveling vehicles;
control ratio detecting means for obtaining a control ratio of an actual value to a target value;
target control value generating means for generating a target control value required for controlling the space between said two traveling vehicles based on said control ratio obtained by said control ratio detecting means in addition to said relative speed obtained by said relative speed detecting means; and
control means for activating said acceleration/deceleration means in accordance with said target control value generated by said target control value generating means.

Abstract
A control ratio (γ) of a distance deviation (Δd) to a target distance (dm) is obtained to control a space between two traveling vehicles. The distance deviation (Δd) is the difference between an actual distance (d) and the target distance (dm). A target control quantity, such as acceleration, engine torque or vehicle speed, is determined in accordance with the obtained control ratio (γ) so as to equalize the actual distance (d) to the target distance (dm).
