Abstract

A system for storing beginning and ending odometer readings of a plurality of individual trips made by a vehicle. The odometer readings for each trip are stored individually for future retrieval and use. The system can be directly connected to an odometer device included on the vehicle, or odometer information can be manually input by the vehicle operator. The date and other data such as the vehicle and operator identify, trip purpose, and customer identification codes, are stored for each trip. A data I/O port is provided to allow direct transfer of data from the system to a central computer where the data can be used by appropriate computer programs. The distance traveled during each trip can be calculated by a central computer, or the system can be programmed to calculate the trip distance. The apparatus is accommodated in a compact housing which slides into a cradle mounted inside the vehicle for convenient relocation from one vehicle to another or to a computer for data transfer. The apparatus is powered by the vehicle power source. The present invention provides an accurate and convenient system for logging the information associated with each trip made by a vehicle so that accurate records can be easily kept on the use of a vehicle.

automatic means for entering and storing the first operator identification character string;

wherein the operator can select between the manual means and the automatic means for entering and storing the first operator identification character string.

7. A system as defined in claim 1 further comprising means for storing a first trip purpose identification character string with the beginning and ending odometer readings of a trip.

8. A system as defined in claim 7 wherein the means for storing a first trip purpose identification character string further comprises:

manual means for entering and storing the first trip purpose identification character string; and

9. A system as defined in claim 1 further comprising means for inputting the amount of fuel consumed during the first trip and for calculating a fuel economy for the first trip.

10. A system as defined in claim 1 further comprising calculation means for calculating the distance between a first origination point and a first destination point to derive a first trip distance value.

11. A system as defined in claim 10 wherein the calculation means comprises a microprocessor.

12. A system as defined in claim 1, further including:

means for generating a signal detectable by the operator when a vehicle ignition switch is activated to thereby prompt the operator to enter a command on the touch actuated input means to produce a signal indicating whether a trip is a continuation of a previous trip;

means responsive to a signal produced by a command of the operator for causing the storage means to store a single beginning odometer reading and a single ending odometer reading for a trip comprising a series of intermediate trips.

13. The system of claim 1 further comprising

error checking means for comparing a presently entered odometer reading with a previously entered reading and for developing an error indication signal if the presently entered reading has a lower numerical reading than the previously entered reading.

14. The system of claim 1 further comprising

means for alerting the operator when the amount of data stored approaches the capacity of the storage means.

15. A system as defined in claim 14 wherein the means for alerting the operator includes means for displaying the number of trips remaining to be stored in the storage means.
