ABSTRACT:
Apparatus for controlling an odometer and speedometer system of a vehicle, adjustable for vehicle parameter variations, such as tire size and axle ratio, including a transducer for generating a plurality of initial pulses in response to vehicle movement which pulses control both the vehicle odometer and speedometer. The initial pulses are multiplied by a multiplying factor to produce a train of pulses for each initial pulse. The multiplying factor is in binary form and is selected either according to the position of an array of switches or according to a number retained in a programmable downcounter. The train of pulses is divided by a fixed number to create a driving signal for the odometer and is converted by a frequency converter to drive the speedometer.
