Method for controlling an opacifying glazing for a motor vehicle

A method for controlling an opacifying glazing unit for a motor vehicle, the glazing unit comprising:

• at least two partitions, an opacity level of each of the partitions being commanded autonomously to change between a minimum value and a maximum value,
• wherein each of the partitions takes a number n of levels of opacity that are numbered in an order of increasing opacity, where n=3 or n=4 or n=5,
• wherein a first type of command for the opacity level of a partition that takes a value of the opacity level of rank j, involves:
• a unit reduction in the value of the opacity level of the partition to a value of the opacity level of rank j−1, or
• a unit increase in the value of the opacity level of the partition to a value of the opacity level of rank j+1,
• and
• a second type of command for the opacity level of a partition that takes a value of the opacity level of rank j, involves:
• a multiple-unit reduction in the value of the opacity level of the partition or a reduction in the value of the opacity level of the partition to a minimum value, or
• a multiple-unit increase in the value of the opacity level of the partition or an increase in the value of the opacity level of the partition to the maximum value, and
• wherein the first type of command is a first press on a control button and the second type of command is a second press on the control button, the first press being shorter than the second press.
