ABSTRACT:
A data handling system for an automobile comprises an odometric data generator which provides odometric data corresponding to the travel distance of the automobile. A nonvolatile memory stores total odometric data, an adder receives the odometric data provided from the odometric data generator and the previous total odometric data provided from the nonvolatile memory, and a control circuit controls the writing of data into the nonvolatile memory in accordance with the state of a key switch. The adder receives the present odometric data and the previous odometric data, to thereby provide total odometric data up to the present time. This total odometric data is displayed by an appropriate display device. In response to the turn-off of the key switch, the total odometric data provided from the adder is written into the nonvolatile memory. Thus, an odometer can be implemented in electronic circuit form.
