CLAIMS

1. An onboard data handling unit for a vehicle comprising;
means receiving vehicular operating data;
means recording said data having first and
second sections;
prerecorded instructions contained in said first section;
means preselecting said data, in accordance with said prerecorded instructions;
means processing said preselected data;
means recording said preselected data in said
second section;
whereby said recording means provides pre- determined recorded vehicular operating data.

2. The onboard unit of claim 1 wherein the first recording section includes unique identification for said unitary recording means.

3. The onboard unit of claim 1 wherein the unitary recording means includes a magnetic tape recorder and . removable cassette.

4. The onboard unit of claim 1, 2 , or 3, wherein the processing means is a micro-processor.

5. The onboard unit of claim 1, wherein said pre-recorded instructions include critical values of predetermined data, and said recorded data is identified when varying therefrom.

6. In a data handling unit for use in a vehicle providing dynamic operating data from preselected input information at any point of a predetermined path, of the type utilizing magnetic tape recording, and a microprocessor for information handling, the improvement comprising;
a removable magnetic tape cassette' having fir and second protions;
prerecorded instructions and identification o said first portion;
a plurality of transponders located at known intervals along the vehicular path;
means identifying said transponders;
means . measuring vehicular travel;
means correcting said travel measurements
relative said transponder location;
means recording said operating data on said
cassette second portion,
wherein, initial unit operation utilizes the
prerecorded instructions to record uniquely ident fied data relative to vehicular travel.

7. In a data handling unit for use in a wheeled vehicle providing dynamic operating data from preselecte input information at any point of a predetermined path, the type utilizing magnetic tape recording, and a microprocessor for information handling, the improvement comprising;
means generating a pulsed signal correspondin to the rotational speed of at least one wheel of
said vehicle;
means determining the period of at least two
said speed pulses;
means generating a pulse train having a predetermined frequency;
means counting said predetermined pulses duri said period;
means enabling said counting means on alterna periods of said speed pulses, generating first an second counts;
means determining vehicular speed correspondi to said counts;
means averaging said speeds;

OMPI WIPO wherein the speed of said vehicle is determined for a predetermined amount of wheel rotation.

8. The improvement of Claim 7 , further comprising;
means responding to said enabling means pro- viding a pulsed signal corresponding to said predetermined pulses during said periods;
means resetting said counting means on
enablement;
means responsive to said pulsed signals;
wherein on cessation of said speed pulses, said responding 'means indicates a stopped vehicle.

9. The improvement of Claim 7 further including display means responsive to said averaged speed, wherein

" said display is updated after said second count.

10. Improvement of Claim 7, wherein the determining means is a table lookup contained in the random access memory of a microprocessor.
