Rearview system with controllable reflectance of a rearview mirror and / or a display for motor vehicles, motor vehicles and method for controlling a reflectance of a color display of a rearview mirror

摘要

The invention relates to a rearview system (1) for a motor vehicle (2), comprising at least one rearview mirror (3, 4) and / or a display, the degree of reflection (R) of which can be controlled by means of an electrical control signal (5); an ambient light detection means (6) which is configured to detect ambient light (7) and to generate an electrical ambient light signal (8) which indicates an intensity (Ia) of the detected ambient light (7); a glare detection means (9) which is configured in such a way that it detects glare light (10) striking the at least one rearview mirror (3, 4) and / or the display and generates an electrical glare light signal (11) which has an intensity (Ig ) the detected glare (10) indicates; and an electronic control unit (ECU) which is configured to receive the electrical ambient light signal (8) and the electrical glare light signal (11) and a light intensity difference between the received ambient light intensity (Ia) and the received glare light intensity (Ig) to determine and the reflectance (R) controlling the at least one rearview mirror (3, 4) by means of the electrical control signal (5) as a function of the determined difference in light intensity; wherein one or more of the ambient light detection means (6) and the glare light detection means (9) is / are at least one photovoltaic cell (13, 14, 17, 18) for generating electrical energy. The invention also relates to a motor vehicle (2) with such a rearview system (1) and a method (100) for controlling a reflectance (R) of a rearview mirror (3, 4) and / or a display for a motor vehicle (2).
