ABSTRACT:
A mile post and mileage indicator for maintaining the exact mile post position of a vehicle while said vehicle is travelling upon a roadway containing designated mile post signs, which increase or decrease in a particular direction. This indicator may also be used to indicate exactly how far the vehicle has travelled or how much further it must travel before it reaches a certain destination. The indicator contains electronic circuits for presetting a specific mileage onto a display and for increasing or decreasing the mileage display in conjunction with a pulser unit placed in the speedometer cable of the vehicle. A calibration unit is utilized which corrects minor errors in signals received from the vehicle transmission.
