Abstract
An electronic trip meter with a correction circuit for an automotive vehicle comprises a counter for producing an ouput signal indicative of a measured distance, an error detector for deriving an error factor of the measured distance with respect to a reference distance, a correction circuit for correcting the measured distance by the error factor, and a display circuit for displaying the corrected distance.
