Travel control system for vehicle
First Claim
1. A travel control system for a subject vehicle, comprising:
- a radar device for detecting preceding vehicles with respect to the subject vehicle;
controlling means for detecting, among the preceding vehicles detected by the radar device, an interested preceding vehicle which immediately precedes the subject vehicle, and for accelerating and decelerating the subject vehicle in response to a condition of the interested preceding vehicle; and
relative speed calculating means for calculating a relative speed between the subject vehicle and a next-lane preceding vehicle among the preceding vehicles detected by the radar device, the next-lane preceding vehicle being a preceding vehicle in a lane next to a lane where the subject vehicle exists;
wherein the controlling means comprises means for executing one of (1) suppression of acceleration of the subject vehicle and (2) deceleration control of the subject vehicle when the relative speed calculated by the relative speed calculating means is smaller than a prescribed negative value.

Abstract
A travel control system for a subject vehicle includes a radar device for detecting preceding vehicles with respect to the subject vehicle. A controlling device operates for detecting, among the detected preceding vehicles, an interested preceding vehicle which immediately precedes the subject vehicle, and for accelerating and decelerating the subject vehicle in response to a condition of the interested preceding vehicle. A relative speed calculating device operates for calculating a relative speed between the subject vehicle and a next-lane preceding vehicle among the detected preceding vehicles. The next-lane preceding vehicle is a preceding vehicle in a lane next to a lane where the subject vehicle exists. The controlling device also operates for executing one of (1) suppression of acceleration of the subject vehicle and (2) deceleration control of the subject vehicle when the relative speed calculated by the relative speed calculating device is smaller than a prescribed negative value.

9. A vehicular travel control system comprising:
-
first means for automatically accelerating a first vehicle;
second means for detecting a second vehicle preceding the first vehicle and being in a lane next to a lane where the first vehicle exists;
third means for detecting whether or not a speed of the first vehicle is higher than a speed of the second vehicle by more than a given value; and
fourth means for suppressing the automatically accelerating of the first vehicle by the first means when the third means detects that the speed of the first vehicle is higher than the speed of the second vehicle by more than the given value.
