Title:
TRAFFIC VEHICLE ANTI-COLLISION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/1995/006305
Kind Code:
A1
Abstract:
A method and apparatus are provided for preventing traffic vehicle from collision with an obstacle, in which the distance between the controlled vehicle and the obstacle is dynamically detected by a distance detector (1) using visible light, that is, an auto-focusing device which has been widely used now, in more detail, the signal when object is in in-focus is output as distance signal; the detected distance and the speed of vehicle detected in other way are input into a microcomputer (3), and are compared with a predetermined speed-distance relation by the microcomputer and determined, then the computer outputs the determined signal to control a speed control system (4). The present invention can automatically limit the speed or brake according to the vehicle speed and the distance between the vehicle and the obstacle to keep some distance between the vehicle and the obstacle during cruising and avoid collision.
