Method and System for Improving the Monitoring of the External Environment of a Motor Vehicle
First Claim
1. A method for improving the monitoring of the external environment of a motor vehicle, of the type which comprises using a detection system to detect the presence of objects which are susceptible to collide with the mentioned vehicle, in a determined surveillance area, covering at least one blind spot, said detection system comprising at least one capturing device suitable for acquiring images representative of one or more objects located within said surveillance area, and an electronic system with at least one system for processing and analyzing input signals obtained by means of said at least one capturing device, and which generates output signals according to the result of said analysis, said method comprises automatically activating an infrared light source to emit infrared light towards the surveillance area to be covered by the capturing device when the images acquired by said capturing device don'"'"'t make possible a processing and an analysis providing a result that would reliably detect a determined object, and deactivating, also automatically, said infrared light source when the electronic system determines, after processing and analyzing the images acquired by the capturing device, that a determined object in said surveillance area can be reliably detected without the need for infrared light.

Abstract
The invention relates to a method and system for improving the monitoring of the external environment of a motor vehicle. According to the invention, the vehicle comprises a built-in system for detecting objects with which it is likely to collide, within a monitored area covering a blind spot, comprising a capturing device for acquiring images that are representative of one or more objects located within said area and an electronic system for processing and analysing input signals. The inventive method comprises the automatic activation of an infrared light source in the direction of the monitored area when the images acquired cannot be processed and analysed in order to provide a result that would reliably detect a determined object and the automatic deactivation of said infrared light source when the acquired images produce the correct result without the need for infrared light. In addition, the system comprises a model with an infrared light source.
