Problems solved by technology

It is thus intended to achieve a more practical control of electrochromic mirrors, although it has a very specific application, which only considers the different degrees of glare-generating light signals incident on the same rearview mirror, but does not consider how to make the electrochromic rearview mirror The control of the mirror is adapted not only to the intensity of the glare-causing light but also to other characteristics of the phenomenon, such as its repetition over time

Embodiment Construction

[0046] A method is proposed to implement an improved decision algorithm to greatly improve the final function of electrochromic rearview mirrors. The key point is based on the fact that the proposed method can identify situations in which continuous glare or glare occurs, such as on arterial roads with high traffic density, secondary arterial roads with many curves (vehicles containing electrochromic mirrors) followed by a vehicle) and many other places.

[0047] In a first aspect, the invention relates to a method of controlling an electrochromic mirror applicable to a rear view mirror of a motor vehicle, the basic operation of which can be seen in FIG. 2 .

[0048] The method consists first of all of carrying out the following successive steps, which are known from the prior art and which are considered in particular by the above-mentioned "conventional decision algorithm":

[0049] a) detecting that a light signal having a light intensity exceeding a certain predetermined ...

Abstract

The invention relates to a method of controlling an electrochromic mirror and to an electrochromic system which are intended for a motor vehicle. The inventive method comprises the following steps: a) detection of the incidence on the mirror of a light signal with a light intensity above a pre-determined threshold; b) upon detection of said signal, the electrchromic mirror darkens to a pre-fixed maximum level of darkness; c) when the light signal is no longer incident on the electrochromic mirror, the mirror lightens to a minimum level of darkness, thereby improving the driver's view of the exterior of the vehicle; d) the electrochromic mirror is lightened or darkened to an intermediate level; e) detection of the incidence on the mirror of a subsequent light signal with a light intensity above a pre-determined threshold; f) upon detection of said signal, the electrochromic mirror is darkened from the intermediate level to a maximum level of darkness; and g) when the subsequent light signal is no longer incident on the electrochromic mirror, the mirror returns to the intermediate level of darkness.

Description

technical field [0001] In a first aspect, the present invention generally relates to a method for controlling an electrochromic mirror suitable for use in a rearview mirror of a motor vehicle, and more particularly, to a method for improving the anti-repeatability of an electrochromic mirror. The method of blinding potency. [0002] In a second aspect, the invention also relates to an electrochromic system suitable for a rear view mirror of a motor vehicle utilizing the proposed control method. Background technique [0003] The problem of dazzle while driving is very important as it affects the ability of the driver of the vehicle. Dazzle can be caused by vehicles approaching the mentioned vehicle from the front and by vehicles behind the mentioned vehicle. The vehicles described are causing the dazzle because they are driven with high beams or with the wrong low beam adjustment. Furthermore, this problem increases significantly due to the increase in the number of four w...
