ABSTRACT:
The process for the control and activation of vehicle dashboard indicators (121, 122, 221) consists in distributing the indicators into x groups (1, 2, 3, 4) of indicators (121, 122, 221) and in performing a time division multiplexing of the groups (1, 2, 3, 4), by determining an actual value of instantaneous excitation of the indicators (121, 122, 221) and by regulating a shape factor for multiplexed control and activation of the indicators (121, 122, 221) as a function of the deviation between the actual excitation value and a preset value.
