Method for controlling and activating indicators on a vehicle dashboard, comprises microprocessor which receives multiplexed sensor signals and multiplexes groups of indicators in matrix array

摘要

A microprocessor (30) supplied from the vehicle voltage (Va) receives multiplexed signals (40) which indicate the state of a group of vehicle sensors. Dashboard indicators such as electroluminescent diodes are arranged as four lines of a matrix controlled by vehicle voltage switches (11-14) and earth switches (31-38). Both groups of switches are operated by microcomputer multiplex signal to activate groups of indicators
