Device for detecting the presence of moisture, water or black ice on the tread (21) of a motor vehicle tyre (27) and device for warning the driver of this detection, characterized in that it comprises at least two temperature sensors of which one, known as the dry sensor, through its configuration and/or type, measures a tyre temperature T1 that is insensitive to the presence of water, and the other, known as the wet sensor, through its configuration and/or type, measures a tyre temperature T2 that is sensitive to the presence of water, said device also comprising a means of comparing the two temperatures picked up by the sensors, and a warning means for alerting the driver if such a detection is made. |
