FIELD: indication of operation characteristics of transportation vehicles.
SUBSTANCE: indicator is intended for usage at representation at least one parameter of motion of transportation vehicle and/or state of its systems. Indicator is connected with embedded network of power supply of transportation vehicle and has control electric signal source, indicator to represent mentioned parameter, and control signal converter to preset modes of operation of indicator. Indicator is made for estimation of change in data, which it provides during driver's perception, by peripheral vision of at least one object of indicator at changes in brightness of luminescence, which accompanies change in electric signal coming from converter. Control electric signal source has electric inductive and/or capacitive coupling with embedded network of power supply, which is made for selection of noises of variable character. The noises are induced in embedded network due to operation of units and assemblies of transportation vehicle at frequency that doesn't exceed 100 MHz. Dynamic range of mentioned controlled signal is provided for taking estimations.
EFFECT: widened area of application of digital indicator.
