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.
