Indicating device

The process for the control and activation of vehicle dashboard indicators () consists in distributing the indicators into x groups () of indicators () and in performing a time division multiplexing of the groups (), by determining an actual value of instantaneous excitation of the indicators () and by regulating a shape factor for multiplexed control and activation of the indicators () as a function of the deviation between the actual excitation value and a preset value.
