ABSTRACT:
A vehicle is equipped with a combination meter system including a plurality of gauges or meters, comprising a plurality of sensors for detecting various characteristics for the operation of a vehicle and a plurality of analog switches operatively connected to the sensors, respectively. A pulse control circuit transmitting pulse signals is connected to the analog switches for selectively operating the analog switches and a decoder circuit is operated responsive to the pulse signals from the pulse control circuit for producing a signal indicating one of the analog switches to which the pulse signal is applied. A distribution circuit is connected to the analog switches and responsive to the signal from the decoder circuit for dividing a signal from the one of the analog switches into two kinds of signals based on the characteristic of one of the sensors corresponding to the one of the analog switches. A plurality of sample and hold circuits are connected to the voltage distribution circuit and respectively corresponding to the analog switches for sampling and holding the two kinds of signals from the distribution circuit, the sample and hold circuits being connected to the gauges or meters, respectively, for driving the same.
