1. A control system for a vehicle comprising,a nearby object detector which detects nearby objects existing around the vehicle and calculates distance between the vehicle and the nearby objects and relative velocity of the nearby objects;
- a velocity detector which detects velocity of the vehicle;
a velocity controller which controls the velocity of the vehicle;
wherein the velocity controller comprises a slow velocity cruising mode which is activated when the vehicle velocity is below a predetermined vehicle velocity value, and a high velocity cruising mode which is activated when the vehicle velocity is above the predetermined vehicle velocity value, and wherein during the slow velocity cruising mode the velocity controller controls a distance between the vehicle and a first object selected among the nearby objects so as to assume a predetermined distance value, and during the high velocity cruising mode the velocity controller controls a distance between the vehicle and a second object among the nearby objects having a ground velocity larger than a predetermined ground velocity value so as to assume a predetermined distance value.

Abstract
An automobile running control system having “Fast follow-up” and “Slow follow-up” modes controls so that the automobile may cruise at an optimum car-to-car space between the automobile and an object which is selected among those detected and faster than a preset ground velocity in the “Fast follow-up” mode. When the fast follow-up velocity of the automobile falls under the preset velocity, the system automatically enters the “Slow follow-up” mode.

7. A control method for a vehicle in which nearby objects existing around the vehicle are detected, distance and relative velocity between the vehicle and the nearby objects are calculated, velocity of the vehicle is detected, and the velocity of the vehicle is controlled,
wherein when the vehicle velocity is below a predetermined vehicle velocity value, a distance between the vehicle and a first object selected from the nearby objects is controlled so that the vehicle assumes a predetermined distance value, and when the vehicle velocity is above a predetermined vehicle velocity value, a distance between the vehicle and a second object among the nearby objects having a ground velocity larger than a predetermined ground velocity value is controlled so that the vehicle assumes a predetermined distance value.
